The images beamed back to Earth of the first civilian spacewalk have prompted a very pertinent question from one Inside Science listener: What effect is space travel having on our climate? We're used to delving into the carbon footprint of Earth-bound travel – so this week we’re going to explore the impact of the rapidly growing space industry on our climate. How does a rocket launch compare to a flight taking off? Do we even know the true cost yet – and if it’s significant, what might the solution be? Also on the programme, a personal perspective from a remote island on worrying seabird declines, the results of a project to refreeze Arctic sea ice, and why new evidence unearthed about the Falkland Islands suggests it may once have looked very different...

Lab-grown meat, cultivated meat, cultured meat, in-vitro meat - whatever you call it, the industry claims it could be a game changer. Not just economically, but for feeding the planet in a sustainable way.But is it too good to be true? And will people even eat it? In this special episode of Inside Science, we take a deep-dive into lab-grown meat; visiting a production facility to see how it's made, hearing about the nuanced perspectives of British farmers, asking if this new industry can learn from the failings of GM foods, and trying to figure out what the true environmental costs of entirely new way of producing food really is.

Today incredible images were beamed around the world of civilians walking in space – for the very first time. All eyes were on businessman Jared Isaacman and engineer Sarah Gillis as they ventured outside a Space X capsule. But is this an historic space exploration milestone - or just a very exciting holiday for a billionaire? We'll find out more from the BBC’s own expert space-watcher Jonathan Amos. Also this week, we visit Sellafield which processes and stores more radioactive material per square metre than any other site in Europe. But it is getting full. So where is our nuclear waste going to go in future? As the UK searches for a new potential site, we look at the science of what we do with nuclear waste and why. We’ll also delve into the fascinating world of nuclear semiotics. How can we communicate the dangers of nuclear waste to people living 100,000 years from now? Presenter: Vic Gill Producers: Sophie Ormiston & Gerry Holt Editor: Martin Smith Studio manager: Cath McGhee Production Co-ordinator: Andrew Rhys Lewis

As the long-awaited final report into Grenfell Tower is made public, we look at the cladding that has been at the centre of the story for seven years.

Space junk. It might sound like an out-of-this-world problem that we don’t need to worry about here on Earth – but is it? As we send more and more metal in the form of satellites up into space, scientists are warning it is becoming more of a risk both here – and up there. We dig into the problem and what’s being done to clean it up. Also this week, we answer a listener question about oceans and their influence on global temperatures, and we ponder the use – and sometimes abuse – of scientific language. And with the Paris Olympics well under way, how much does sex affect sporting performance? Presenter: Victoria Gill Producers: Ella Hubber & Gerry Holt Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth

CERN’s plans to build a bigger, faster particle collider, with a hefty 17 billion Euro price tag, are in question. Physicists Andrew Pontzen and Harry Cliff discuss if the new machine is really worth it. A place on the podium or disappointment in the Olympics can come down to the precise position of a foot or angle of the hips. Science reporter Ella Hubber visits the University of Bath to check out the motion capture tech that makes these measurements. New research suggests our close cousins, the chimpanzees, chat just as fast as humans. Professor Cat Hobaiter from the University of St Andrews tells us what chimp chats can teach us about the evolution of language. 75 years after making a groundbreaking discovery, Rosemary Fowler has finally been awarded with an honorary doctorate. University of Bristol chancellor, Sir Paul Nurse, shares how important it is to celebrate and recognise Rosemary’s achievements.Presenter: Victoria Gill Producers: Ella Hubber and Sophie Ormiston Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth

Antarctica is a 'natural reserve, devoted to peace and science' - that’s according to an international treaty. But with visitor numbers at a record high, how does tourism fit into that – and what kind of impact is it having on its fragile ecosystem? We discuss whether tourists – and even scientists – should be allowed to go at all. Swimming in the Seine has been banned for more than a century because of pollution concerns. The main culprit? Human waste. We find out if it really will be safe in time. And every summer we ready ourselves for 'flying ant day' – that one day where winged ants take to the skies across Britain. Or do they? Presenter: Victoria Gill Producers: Sophie Ormiston, Ella Hubber and Gerry Holt Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth

The looming danger of antibiotic resistance may have fallen out of the public consciousness but is still very much in the mind of those in public healthcare and research. As promising new research is published, the University of Birmingham’s Laura Piddock and GP Margaret McCartney get to the bottom of why antibiotic resistance is still so difficult to tackle. Marine biologist Helen Scales joins us in the studio to talk about her new book “What the Wild Sea Could Be” which uses changes in the Earth’s past to predict what we can expect to happen to our oceans in the coming years. Cosmologist Andrew Pontzen speculates on what happens in and around the extreme environment of a black hole as news of the first observations of the “plunging zone” comes to light. And as the EU head to ban smoky flavoured crisps we ask what the science behind this decision is with Food scientist Stuart Farrimond.

Guest presented by Liz Bonnin.We all instinctively know that sleep is incredibly important but science doesn’t actually have a satisfying answer for why we need to sleep. There are multiple theories, but now, new research from Imperial College London has suggested that the leading idea might actually be incorrect. Science journalist Ginny Smith explains.Nearly 80 years ago, one of the rarest elements in the world, promethium, was first discovered, but it’s properties have only now been revealed. Andrea Sella, Professor of Chemistry at University College London, tells us what this means.What’s the scariest animal on the planet? Lions, crocodiles, or maybe tigers might come to mind. Yet a recent study has found that animals around the globe fear our voices far more than sounds of any other predators. Professor Liana Zanette explains how her research could help conservation efforts.Finally, we answer one of your questions. Listener Mary Evans got in touch to ask: ‘do you think it's likely that people who are widely travelled and used to eating local food and drinking tap water would have more diverse bacteria in their gut?’ Expert on all things microbiome, Megan Rossi, joins us in the studio to answer Mary’s query.

Guest presented by Liz Bonnin. As the UK strives to achieve net zero by 2050, nuclear energy is looking more and more likely as a key player in reaching this goal. But it’s not just massive power plants like Hinkley point C - there’s are newer smaller reactors on the scene: small and micro modular reactors. 100 to 1000 times smaller than a conventional reactor, faster to build, and put together entirely in a factory before being shipped out, theoretically, anywhere: are micro modular reactors the future of nuclear energy or too good to be true? Dean of Engineering at the University of Liverpool, Eann Patterson, has just published a paper proposing a fleet of micro modular reactors to bear the burden of our energy load and he joins us to discuss the reality. What came first, the chicken or the egg? Science writer, broadcaster and now egg expert Jules Howard joins us to answer this age old question. His book Infinite Life tells the story of how the egg propelled evolution – whether it’s bird, insect, or mammal. This month, scientist Alexandra Freeman’s appointment to the House of Lords was announced. With a background in risk and evidence communication, Alexandra tells us why she applied, what she hopes to achieve, and how the public can get involved.

Last week, a girl who was born deaf had her hearing restored following gene therapy. In the US, the first commercial gene therapy for sickle cell disease has just begun. And Great Ormond Street Hospital has found great success in their trials and a gene therapy for children lacking an immune system. Gene therapy is clearly having a moment. But how do these groundbreaking therapies actually work? And will they ever be truly accessible to everyone? Geneticist Professor Robin Lovell-Badge answers all. Also this week, atmospheric scientist Laura Wilcox answers an interesting listener question about the effect volcanoes can have on the weather and sticks around to dig into the connection between aerosols and weather in different regions. The exhibition “Bees: A Story of Survival” opened at the World Museum in Liverpool this month. Part of the show explains the how honeybees communicate through vibration. Physicist Martin Bencsik, who collected and studies these vibrations, plays us a few and explains their meaning. And did you get a chance to see the auroras that covered a large part of the Northern Hemisphere last weekend? The intense solar activity that caused them has some people alarm. Jim Al-Khalili, who has written a science fiction novel based on the concept, talks what is protecting us from solar flares and what could go wrong. Presenter: Marnie Chesterton Producers: Ella Hubber, Sophie Ormiston and Hannah Robins Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth

There has been increasing public outrage at raw sewage discharges into our rivers and seas, but new research at Lake Windermere suggests that treated sewage is as much to blame. Wastewater experts Simon Evans and Ali Morse get into the nitty gritty of sewage treatment and why it might be causing so many problems. Last week, the Sumatran orangutan Rakus made headlines when he was spotted by researchers treating a wound with a medicinal plant. A first for a wild animal. But he’s not the only animal to show self-medicating behaviour. Biologist and author of Wild Health, Cindy Engel, talks healing in the wild and what we can learn from the animals that do it. And it’s that time of year again: the Eurovision Song Contest. In fact, this year marks the 50th Anniversary since ABBA won the 1974 contest with the iconic track Waterloo. Psychology and behavioural researcher Harry Witchel tells us what gives songs at Eurovision a winning edge and tries to predict a winner based on his criteria.

One year ago, the World Health Organisation declared that COVID-19 would no longer be categorised as a global health emergency. But the pandemic has left us with a new normal in all areas of our lives. From vaccine rollout to wastewater monitoring, we’re asking: how has COVID altered the scientific landscape? Marnie Chesterton is joined in the studio by Linda Geddes, science journalist, and Barbara Kasprzyk-Hordern, Professor in Environmental and Analytical Chemistry at the University of Bath, to discuss.Are ugly animals getting the short end of the conservation stick? Whilst a few beautiful creatures, like tigers and panda bears, get good marketing and attract the most conservation efforts, comedian and biologist Simon Watt argues that the endangered animals which are less pleasing to the eye are being forgotten.Also this week, we answer a listener’s question about the accuracy of using bug splats on cars to measure insect populations. Lead data analyst from the Kent Wildlife Trust, Lawrence Ball, gives us the details about the national citizen science survey, Bugs Matter, which sees people around the country measure insect splats on vehicle number plates as a marker of insect abundance.And science journalist Roland Pease discusses the unprecedented scientific opportunity hurtling towards Earth in the form of asteroid Apophis. It will just miss our planet – in astronomical terms at least – but its proximity has astronomers excited.

As the UN tries to get a global agreement on plastic waste we hear from two delegates at the conference in Ottawa; John Chweya, a Kenyan waste picker, and plastics scientist, Steve Fletcher, discuss the impacts of plastic pollution and the possible solutions. Taylor Swift’s new album, The Tortured Poets Department, exposes the pain a break up can cause. Heartbreak is a common theme in music and art – but what does science have to say about it? Florence Williams, science journalist and author of Heartbreak: A Personal and Scientific Journey, talks us through the research on what actually happens in our bodies when we go through a break-up. The nomadic Avar empire ruled over eastern and central Europe from the sixth to the ninth century but very little was known about them – until now. From studying ancient DNA, researchers have discovered a wealth of information about how the Avars lived. Dr Lara Cassidy, Assistant Professor in Genetics at Trinity College Dublin, explains the findings, and how it’s even possible to learn so much from ancient DNA. We all know how bees great are – but what about all the other pollinators? Dr Erica McAlister from the Natural History Museum in London speaks out in defence of the fly. Presenter: Victoria Gill Producers: Hannah Robins and Sophie Ormiston Editor: Martin Smith

Earlier this week, some of the world's leading astrophysicists came together at The Royal Society to question the very nature of our Universe. Does the Lambda Cold Dark Matter model, which explains the evolution of the cosmos and the Big Bang, need a rethink? Dr Chris North, an astrophysicist from the University of Cardiff, joins us in the studio to explain what this model says, and why it might need to be changed. The last few weeks seem to have been a non-stop cycle of depressing climate stories, with floods in Pakistan, mass coral bleaching and last month being the hottest March ever recorded. It's perhaps no surprise that many people are anxious about the news. Vic Gill is joined by Prof Lorraine Whitmarsh, an environmental psychologist at the University of Bath, and Tom Rivett Carnac, an author, political strategist and co-host of the podcast Outrage + Optimism. Together they discuss climate anxiety, and how to stay engaged with the news without feeling overwhelmed.And with all this wet weather, how are our precious insects faring? It turns out, bumblebees might have a trick up their fuzzy sleeves when the ground gets flooded - at least according to a new experiment led by Sabrina Rondeau from the University of Ottawa. We also get bumblebee expert Dave Goulson on the line to tell us more about these charismatic insects.

A strain of highly pathogenic bird flu, H5N1, has been spreading unchecked through wild bird, and some mammal, populations for the past few years. Last week, news of a large number of dairy cows in the USA being infected with bird flu has alarmed the public and virologists alike. One farm worker has also picked up the virus and although they are not seriously ill, the jump between cattle and humans raises serious concerns over how the virus is moving and adapting. Virologist Dr Tom Peacock has the details. Also this week, thousands of eyes across America were turned to the skies to catch a glimpse of the total solar eclipse. But this event isn’t just a spectacle for the eyes – it’s a real scientific opportunity. Space physicist and electrical engineer Dr Nathaniel Frissell reveals his unusual approach to studying the eclipse via radio. And BBC reporter Georgina Rannard, who has been following the eclipse this week, tells Vic what other research scientists investigated during the four-minute window of darkness. And don’t turn your eyes away from the sky just yet, as another celestial spectacle is set to occur. About 3,000 light-years away, a pair of orbiting stars called T Coronae Borealis are not normally visible from Earth. But every 80 years or so, one of the stars in the binary system explodes, creating a ‘new’ star in our night sky. But you’ll only have a day or two to spot it. Astrophysicist Dr Rebecca Smethurst joins Vic in the studio to talk about this once-in-a-lifetime star explosion. And to close the show, the life and work of a legend. Nobel Prize-winning physicist Peter Higgs has died at the age of 94. Higgs’s biographer Professor Frank Close tells us how Higgs predicted the existence of a particle that’s fundamental to our understanding of the Universe and reveals the legacy he’s left behind. Presenter: Victoria Gill Producers: Alice Lipscombe-Southwell and Ella Hubber Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth

In 1824, 200 years ago, Megalosaurus was the first dinosaur to ever be described in a scientific paper. William Buckland studied fossils from Stonesfield in Oxfordshire in order to describe the animal. In this episode, Victoria Gill visits palaeontologist Dr Emma Nicholls at the Oxford University Museum of Natural History, who shows her those very fossils that launched the new science of palaeontology. Danielle Czerkaszyn then opens the archives to reveal the scientific illustrations of Megalosaurus by Mary Morland, which helped shape Buckland's description.But this was just the beginning. Over the coming decades, remains kept being discovered and scientists were gripped with dinosaur mania, racing to find species. Now, in 2024, we're finding new dinosaurs all the time. Victoria travels to the University of Edinburgh to meet Professor Steve Brusatte and Dr Tom Challands as they start extracting a dinosaur bone from a piece of Jurassic rock - could this be a new species? Together, they reflect on how palaeontology has changed over the last 200 years and ponder the ongoing mysteries of these charismatic animals.Presenter: Victoria Gill Producers: Alice Lipscombe-Southwell and Hannah Robins Production Co-ordinator: Jana Bennett-Holesworth  Editor: Martin Smith

Microbiomes are a multi-million-pound industry. Every week, many people send off poop samples to be examined so we can learn about our own ecosystems of bacteria, virus and fungi that live in our guts, with a view to improving health. But how accurate are these tests? Microbiologist Prof Jacques Ravel is calling for better controls in what is currently an unregulated industry. He joins us along with Prof Tim Spector, scientific co-founder of personalised nutrition app ZOE, to discuss the areas of concern, and potential benefits, of this direct-to-consumer model. Nobel prize-winning psychologist Daniel Kahneman has died at the age of 90. Widely acknowledged as one of the world's most influential psychologists, his many years of study centred on how and why we make the decisions we do. In 2011, his book Thinking, Fast and Slow, which summarizes much of his research, was published and became a best seller. We’re joined by presenter and author Claudia Hammond to unpick his legacy. The price of lab monkeys has plummeted. Used for drug development and testing, their value skyrocketed during the vaccine development period of the pandemic. But when the boom for vaccines died, the demand for (and value of) these monkeys plunged. Journalist Eleanor Olcott provides the full picture.  Are there alternatives to animal testing? Marnie visits a lab in Cambridge to find out about neural organoids, cellular clumps grown from stem cells made to replicate the brain. Developmental biologist Prof Madeline Lancaster shows her around and Dr Sarah Chan from the University of Edinburgh digs into the ethics of this cutting-edge branch of science.Presenter: Marnie Chesterton Producers: Florian Bohr, Hannah Robins, Louise Orchard and Imaan Moin Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth  BBC Inside Science is produced in collaboration with the Open University.

Professor and presenter, Chris Lintott, talks about his new book Our Accidental Universe; a tour of chance encounters and human error in pursuit of asteroids, pulsars, radio waves, new stars and alien life. Even with incredible technological developments, the major astronomical events of the past century are largely down to plain ol’ good luck; discovered not, as you might assume, by careful experiment, but as surprises when we have been looking for something else entirely. For instance, the most promising habitat for life beyond Earth turns out to be Saturn's tiny moon Enceladus, whose oceans were revealed when NASA's Cassini probe did a drive-by and, we get the most from the Hubble Space Telescope by pointing it at absolutely nothing! A new company has launched which aims to mine Helium-3 on the moon to sell on Earth. This rare isotope is used for supercooling quantum computers and some scientists dream of using it in nuclear fusion as a new source of renewable energy. But is this ambition realistic and, if so, could it be within reach anytime soon? Planetary scientist Sara Russell of the Natural History Museum explains all. There are many moons in our solar systems, but one of the strangest is Titan; the largest moon of the Saturn system. It gets colder than 100 degrees Celsius and has a thick atmosphere that creates weather. But its biggest mystery is the enormous, coffee-coloured dunes that cover a large part of its surface. Where did they come from? Planetary scientist Bill Bottke has a cunning theory. In our universe, some stars are twins. They originate from the same molecular clouds and should be identical, but some pairs are not as similar as you’d expect. Marnie speaks to astrophysicist Yuan-Sen Ting about his new paper which illuminates how this difference might occur. His theory is that one of the stars, perhaps the evil twin, has been busy eating up vulnerable planets...  Presenter: Marnie Chesterton Producers: Louise Orchard, Florian Bohr and Imaan Moin Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth  BBC Inside Science is produced in collaboration with the Open University.

The world’s oldest fossilised forest was uncovered in Somerset last week. We head to palaeobotanist, Dr Christopher Berry’s, lab at Cardiff University to learn about these cladoxylopsids. They lived 390 million years ago and although they are not the ancestors of today’s trees, they reveal some extraordinary evolutionary secrets. Also, Marnie speaks to Dr Chris Thorogood of the University of Oxford Botanic Gardens about his new book Pathless Forest: The Quest to Save the World’s Largest Flowers. Called “Rafflesia” plants and found in the remotest parts of South East Asia, their flowers burst from the rain forest floor the size of pumpkins and are critically endangered. Chris talks of his world of extreme fieldwork and hair-raising expeditions, braving leeches, lizards and lethal forest swamps, to discover the rarest of rare blooms. Plus, the Wildlife Trust’s Making Friends with Molluscs campaign starts today, and I’m sure many gardeners will declare this an impossible task! We visit some allotments in Bristol to find out how people are managing slug and snail populations. And chat to Brian Eversham from the Trust of Bedfordshire, Cambridgeshire and Northamptonshire, who explains why these garden creatures should be considered our friends, not foes. And finally, Dr Stewart Husband from last week’s programme returns to answer more of your burning questions about your tap water.

A recent study on how to get rid of microplastics in water sparked presenter Marnie Chesterton’s curiosity. When she turns on the tap in her kitchen each day, what comes out is drinkable, clean water. But where did it come from, and what’s in it? Dr Stewart Husband from Sheffield University answers this and more, including listener questions from around the UK. Is water sterile? Should I use a filter? And why does my water smell like chlorine? Also, new research indicates that bumblebees can show each other how to solve puzzles too complex for them to learn on their own. Professor Lars Chittka put these clever insects to the test and found that they could learn through social interaction. How exactly did the experiment work, and what does this mean for our understanding of social insects? Reporter Hannah Fisher visits the bee lab at Queen Mary University in London. And finally, more than 20 million years ago, our branch of the tree of life lost its tail. At that point in time, apes split from another animal group, monkeys. Now, geneticist Dr Bo Xia at the Broad Institute of MIT and Harvard thinks he may have found the specific mutation that took our tails. Marnie speaks with evolutionary biologist Dr Tom Stubbs from the Open University about why being tail-less could be beneficial. What would a hypothetical parallel universe look like where humans roam the earth, tails intact? And what would these tails look like?

Switzerland has submitted a proposal to create a United Nations expert group on solar geoengineering to inform governments and stakeholders. The idea was discussed at the UN Environment Assembly in Nairobi, Kenya, this week. Professor Aarti Gupta shares how, after tense negotiations, the different member states could not agree, and the proposal was withdrawn. Why is solar geoengineering a controversial issue? How would dimming the sun even work? And should we consider it a genuine option in our fight against climate change? Dr Pete Irvine and Professor Joanna Haigh join presenter Marnie Chesterton in the studio to discuss. Animal welfare charities have been celebrating a ban on donkey skin trade, agreed to this month by 55 African countries. This will make it illegal to slaughter donkeys for their skin across the continent, where around two thirds of the world’s 53 million donkeys live. Victoria Gill tells Marnie that the demand for the animals' skins is fuelled by the popularity of an ancient Chinese medicine called Ejiao, believed to have health-enhancing and youth-preserving properties and traditionally made from donkey hides. Lastly, Dr Jess Wade, physicist and science communicator at Imperial College London, discusses Breaking Through: My Life in Science. It’s the memoir of Nobel Prize-winning biochemist Dr Katalin Karikó, whose passion and dedication to mRNA research led to the development of the life-changing COVID mRNA vaccines.

Professor Ben Garrod guest presents. As a new 'meaty rice' is created and Fortnum & Mason launch a scotch egg made with cultivated meat that they hope to have on sale as early as next year, we investigate the world of laboratory-grown meat. Mark Post made the first ever synthetic meat in 2012 to the tune of £200,000. He tells us how these lab-grown meats are made and how, he thinks, they could play an important role in reducing greenhouse gas emissions and feeding a growing population. Jenny Kleeman, author of Sex, Robots and Vegan Meat, is more sceptical, citing concerns over food security and if the public really want to eat this stuff. A stingray called Charlotte has become pregnant, despite there being no other stingrays in her tank at the Aquarium & Shark Lab in North Carolina. Marine biologist Dr Helen Scales considers how this may have happened. And cosmic minerologist Sara Russell from the Natural History Museum tells us how astronomers tracked and found a particularly unusual asteroid entering Earth’s atmosphere and what we might learn from it.  Presenter: Professor Ben Garrod Producers: Hannah Robins, Florian Bohr, Alice Lipscombe-Southwell and Jonathan Blackwell Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth  BBC Inside Science is produced in collaboration with the Open University.

The Gulf Stream, also known as the Atlantic Meridional Overturning Circulation (AMOC), is essential to stable global climate, and the reason we have moderate temperatures in Northern Europe. Now, a new modelling study suggests that this circulation could, at some point, be at a tipping point and collapse. We hear from one of the minds behind the model, post-doctoral researcher René van Westen from Utrecht University. But how likely is it that this will actually happen in the real world? Presenter Victoria Gill speaks to Jonathan Bamber who cautions that a gulf stream collapse is not imminent, and that it may just weaken slowly over time. Every summer in the Hudson Bay, on the Eastern side of Arctic Canada, the sea ice melts and the region’s polar bears head inland. But that ice-free season is getting longer, depriving the bears of that frozen platform that they use to pounce on their favourite prey – seals. So what do the bears do all summer? Research Wildlife Biologist Karyn Rode shares how she and her colleagues put a collar with video cameras on 20 polar bears, and what it revealed about their lives. Is CERN finally going to get a gigantic new particle accelerator? Almost exactly one decade ago, Roland Pease reported from Switzerland about the very first meeting about the successor of the Large Hadron Collider which was used to discover the Higgs Boson. Now there’s an update to the story. Roland is back to tell Vic how far along CERN is with their plans, and how much more time and money it will take to build the Future Circular Collider. Lovers of certain famous, creamy French cheeses could be in for a bit of a shock. Camembert and Brie are facing extinction as we know them! The Centre National de la Recherche Scientifique (CNRS) in Paris has stated that, over the last 100 years, the food and farming industry has placed too much pressure on the production of these types of cheeses. Now, the fungus traditionally used to grow the famous, fluffy white rinds has been cloned to a point where the lack of diversity in its genetic makeup means it can no longer be reproduced. Turophiles must learn to appreciate more diversity of tastes, colours and textures to protect the cheeses’ future.

As part of the Vesuvius Challenge, computer scientists have used machine learning to successfully reveal 2,000 characters from the Herculaneum scrolls. These artefacts were charred to a crisp following the eruption of Vesuvius in 79 AD. Papyrologist Federica Nicolardi has been translating the writings, and tells us what exactly has been deciphered. Following this week’s launch of NASA’s PACE satellite, NASA scientist Dr Susanne Craig tells us how the mission will be giving our planet a health check. Bird flu is still an issue. This month, scientists have reported that hundreds of penguin chicks have died from the virus in the Falklands. Meanwhile, in Argentina, avian flu has killed huge numbers of elephant seal pups. Professor Wendy Barclay, a virologist from Imperial College London, tells us more about the virus and how it can jump between species. Sunday 11th February is International Day of Women and Girls in Science. Physicist Dr Jess Wade, who has written hundreds of Wikipedia biographies of women and underrepresented scientists, reveals one of her favourite scientists that people haven’t heard of.

Are cyborgs now reality? Elon Musk certainly thinks so. His company, Neuralink, has successfully implanted one of its wireless brain chips in a human. Although billed as a breakthrough, they’re not the first to do it. In fact, similar devices have already been implanted, all with the aim of connecting our brains to computers with the aim of tackling complex neurological conditions. Joining Inside Science is neuroscientist and author, Dean Burnett. In this episode, Dean helps to break down the technology behind the brain-computer interface and digs into the ethical implications. Plus, game changing smart technology gets a run out as Rugby Union’s Six Nations Championship kicks-off. This year, all players will be wearing “Smart Mouth Guards.” These are intelligent gum shields containing miniature gyroscopes, accelerometers and Bluetooth, which provide - with incredible accuracy - a measure of the magnitude and frequency of forces experienced by players. An athlete making their international debut in this competition could have their entire collision history mapped from now until retirement, providing invaluable information for training and treatments. Crucial not only for elite squads, but ultimately for community and schools rugby where the technology will eventually land, leading to a safer game. And finally, it turns out that we can actually understand chickens even if we’ve never met them before! After assessing a group of around 200 volunteers, a team at the University of Queensland has discovered that humans with no experience of chickens at all, could understand the birds’ calls of satisfaction, or frustration. The research has serious implications for what’s known as precision farming, an area of livestock farming with little, to no, human interaction that requires automated systems of welfare detection using sound recognition.

Hydrogen has long been touted as a potential wonder gas that could play a significant role in our race to net zero. Now, planning permission has been granted for the UK’s largest production hub of its kind, and one of the most advanced in the world. Located in Cheshire, it bills itself as a vital piece of Northwest England’s mission to help manufacturers in the region decarbonise their processes and support UK jobs. We speak to chemical engineer and the plant’s site manager, Richard Holden, and we also catch up with Mark Miodownik, Professor of Materials and Society at University College London, about hydrogen and our future energy economy. Almost 25 years ago, Dr Marc Lammers stumbled across a mystery. The humpback whale singing he was recording via an underwater microphone near the shore was quieter during the day than at night. But he wasn’t able to answer why. Many years later, a PhD student, Anke Kuegler, joined his research team and took on the task of uncovering what was really going on. Using multiple ways of listening to and tracking the whales, she found out that the singing humpbacks were moving off-shore during the day, and closer to shore at night. Part of the mystery was solved, but it raised an even bigger question: what is driving this behaviour? Plus, a recent study has shown that terrestrial hermit crabs around the world are using non-organic materials, like plastic bottle caps, as their homes. Professor Marta Szulkin and her team at the University of Warsaw looked through social media photographs and videos (known as iEcology, or Internet Ecology) to find evidence for this new behaviour. Marta has theories about why the crabs are doing this, but it will take many years of research to uncover the long-term effects on hermit crab populations and their evolutionary trajectory. And, resident materials expert, Mark Miodownik, chats to Viv about what we can, and cannot, solve about the global plastic emergency.

As lava consumes homes on the Reykjavik Peninsula in Iceland, evacuated communities have been witnessing eruptions shifting and intensifying. We take a look at the latest science that’s helping teams on the ground accurately predict where the danger is coming from, helping people to stay safe. Our go-to volcanologist, Dr Evgenia Ilyinskaya, and her colleague, Professor Andrew Hooper, from the University of Leeds tell presenter Victoria about these new technological advancements, and ask the crucial question: are we entering a new millennium of volcanic activity in Iceland? When looking at clear ocean water, you might assume that, aside from fish and some algae, there isn’t much living in it. But Prof Carlos Duarte knows it is full of life. In fact, his new study shows just how many different microbes – bacteria, viruses & fungi – live in all parts of our ocean. He and his team at King Abdullah University of Science and Technology in Saudi Arabia have created the largest ocean genome catalogue to date. Prof Mark Blaxter from the Wellcome Sanger Institute joins us to discuss this new study, the benefits of hypothesis-free science, and why he believes cataloguing the code of life of all the species on earth is an important endeavour. And, lastly, an old dinosaur fossil in New Mexico has been re-examined. What was believed to be of the infamous Tyrannosaurus rex may have been a different species all along. But not all palaeontologists agree. How do scientists even tell a dinosaur species from a fossil? Prof Stephen Brusatte tells Vic that it’s all about comparing bones.

When Lois Pryce arrived at her boat in Berkshire, the area was already completely flooded. The only way to get to it was via a small pontoon. She is one of many across the UK that have been affected by the current floods, and is very familiar with the flood warning system accessible to the public. But how exactly does this system work? What information is taken into account? Marnie Chesterton speaks to Dr Linda Speight about flood forecasting, and the delicate balance of when to send out flood alerts and warnings. Plus, a supersized spacecraft is launching this October. Europa Clipper will assess whether the most intriguing of Jupiter’s 95 moons is habitable, meaning, could it support life? The evidence is tantalising. Jenny Kempmeir, Science Systems Engineer at NASA’s Jet Propulsion Laboratory, tells us why Europa might be the second body in our solar system on which life could exist. And, if you’ve been procrastinating over the housework – or should we say, mousework? - take a leaf out of a little rodent’s book. Apparently, mice do like to keep things clean, but a video that went viral this week seemingly takes this idea to another level entirely! You may well have seen the footage of a Welsh mouse gathering up objects in a shed and placing them neatly inside a box, night after night. It’s certainly very cute - Tidy Mouse carrying out its mousekeeping..but what’s the scientific explanation behind this curious behaviour? Finally, how do exercise and video games affect cognitive performance? Professor Adrian Owen is launching a new experiment to find out and he needs your help.

2024 is an exciting year for lunar exploration. For Inside Science this week Marnie Chesterton investigates the planned missions to the Moon over the next twelve months. It’s been more than fifty years since the last manned mission to the Moon was completed. But that’s about to change with NASA’s upcoming Artemis II mission. This will not only be the first manned lunar flyby of the Moon since 1972, but also the first mission to have a woman and person of colour on board. Reid Wiseman, Commander of the Artemis II manned mission explains more about the mission and even lets us into a few secrets about what culinary delights await astronauts in space. But it’s not just NASA going to the Moon in 2024. China’s Chang’e 6 mission is lifting off in May, aiming to collect samples of rock from the far side of the moon. Quentin Parker, Director of the Laboratory for Space Research at the University of Hong Kong has a unique insight into China’s mission and has been following progress.

Marnie Chesterton & Victoria Gill embark on a science-themed version of the classic Christmas song ‘The 12 Days of Christmas’ in this festive edition of BBC Inside Science. Twelve of the biggest moments of the year in science include discussion about a very special treefrog discovered in the Ecuadorian Andes. We also hear about two new promising drugs for Alzheimer’s disease. An astronomer and visualisation scientist tells us about three new sonifications of space data. There’s more on the discovery of a 476,000 year-old wooden structure found earlier this year in Zambia and how it has changed archaeologists' understanding of ancient human life. The year has also seen 5,000 new species discovered in a deep ocean abyssal plain. Saturn has 62 new moons and is now the planet with the most moons in our solar system. A report was published deeming 75% of UK rivers as posing a risk to human health. We gathered together experts from Natural Resources Wales, Cardiff University, Bangor University and the Wye and Usk Foundation who discussed why the help from citizen science is essential for their work. And a new record has been set which is really worrying scientists - the highest average global ocean surface temperature, which reached 20.98 degrees centigrade. Other notable moments from the year include: a Japanese twelve-legged robot, eighteen video-calling parrots, proposals for the 10km long Einstein telescope and the theory behind why one player in every football team views the world slightly differently. To help us along the journey the BBC’s Radio Drama Company put all the science together into a brand-new rendition of the well-known 12 days of Christmas song.

We’re on board the RSS Sir David Attenborough for the vessel’s first big science season in the Antarctic, since it launched in 2020. It’s crewed by scientists involved in Project Biopole, a 5-year mission attempting to better understand carbon cycle at the poles. Nadine Johnston, a microbiologist with the British Antarctic Survey, joins Inside Science to talk about her work on copepods; zooplankton that build up huge fat reserves over the spring and summer months, then hibernate at 3000m during winter, taking carbon with them which is then locked-up in the deep ocean for up to 600yrs! Her research is a world first in the Southern Ocean and could help improve global carbon modelling of the earth system. Staying in the South Pole, neuroscientist John-Antoine Libourel, talks about his latest research into the surprising sleeping habits of chinstrap penguins. And after weeks of intense earthquake activity, the volcano on the Reykjanes peninsula of south-west Iceland has erupted. Dr Evgenia Ilyinskaya, our go-to volcanologist, provides an update. Plus, a nod to the festive season, as composer and AI artist, LJ Rich, explains why Christmas music makes us feel all fuzzy.

COP 28, the largest climate summit in history, has drawn to a close. Marnie Chesterton examines some of the main stories to emerge from this lengthy conference. The way we look after our oceans, measures needed to ensure food security and an agreement to transition away from fossil fuel dependence were some of the big themes of the summit. The BBC’s climate reporter Georgina Rannard takes us through the final agreement. We hear from Glada Lahn, senior research fellow at international affairs think-tank Chatham House, who explains how we might one day wean ourselves off so-called ‘brown energy’. Farming is also a source of greenhouse gases. Growing, processing and packaging food account for a third of all greenhouse gas emissions. How we feed the 8.1 billion of us on the planet continues to be a contentious issue. Casper Chater from Royal Botanic Gardens Kew explains what we can do to adapt our existing crops to cope with more frequent flood and drought events. Oceans are warming, losing oxygen and acidifying. Sea levels are rising. We speak to Ko Barrett, a senior climate advisor at the US's National Oceanic and Atmospheric Administration, about the role oceans have played so far in helping us mitigate the worse effects of climate change. And we meet Mervina Paueli, a 25-year-old Tuvaluan negotiator, whose small archipelago in the South Pacific is on the frontline.

Vagrant birds are those that appear in locations where they are not usually found. They might have been blown off course by a storm or have been affected by changing weather patterns due to climate change. Although a treat for birders, these visitors can also have a big impact on their new environments as Victoria Gill finds out when she heads to Burton Mere Wetlands on the Dee Estuary with Dr Alexander Lees, reader in biodiversity at Manchester Metropolitan University.As former Prime Minister Boris Johnson gives his testimony, we hear the latest from the UK Covid-19 Public Inquiry with BBC Health Reporter Jim Reed. A new study reveals that, contrary to a commonly-held view, the brain does not have the ability to rewire itself to compensate for the loss of, for example sight, an amputation or stroke. This is despite what most scientists believe and teach. Moreover, the assumption that it has this ability has led to all manner of erroneous treatments for amputees, stroke victims and other conditions, the study suggests. We’re joined by the study’s authors, Professor John Krakauer from Johns Hopkins University and Professor Tamar Making of the University of Cambridge. We’ll also hear from one of Tamar’s key case studies, Kirsty Mason, an amputee from the age of 18 who advanced the scientists’ experiments exponentially.   Presenter: Victoria Gill Producers: Hannah Robins and Louise Orchard Editor: Richard Collings Production Co-ordinator: Jana Bennett-Holesworth  BBC Inside Science is produced in collaboration with the Open University.

Tunnels have been the focus of much attention this week as the war in Gaza continues and 41 workers were rescued in India, after 17 days trapped underground. Forensic geoscientists Jamie Pringle and Ruth Morgan explain the science behind identifying what’s beneath the surface, from above ground, and how you might work out what a tunnel is being used for. This winter, the Northern Lights are going to be the most spectacular they’ve been in twenty years. With the aurora borealis already appearing as far south as Stonehenge, Katie Herlingshaw, a space physicsist from the University Centre in Svalbard, explains what’s happening. The Conference of the Parties, or COP28, begins in Dubai. BBC’s Georgina Rannard gives us the rundown of which countries are the best and worst for sticking to climate goals and assesses the UK’s own standing after Rishi Sunak rowed back on key climate commitments earlier this year.   The UK Covid-19 Inquiry hears from some of the most important ministers this week as key government ministers give evidence.

Key scientific witnesses including former Chief Scientific Adviser Patrick Vallance and Chief Medical Officer for England Chris Whitty are called to the UK Covid-19 Inquiry. The BBC’s Jim Reed brings us his three key moments from the evidence heard over the past few days that have been dubbed “science week”. NASA has managed to let loose a tool kit in the Earth’s orbit -- and you can even see it in the night sky with binoculars. Lucinda King explains how this is possible and if space junk is getting out of control. The United Nations has warned we’re heading towards 3 degrees warming and another Conference of the Parties, known as COP, is about to take place. The BBC’s Georgina Rannard reminds us there is still hope for our planet to curb global warming. The winner of the 2023 Royal Society Trivedi Science Book Prize was announced on Wednesday night. It’s Ed Yong for his book ‘An Immense World: How Animal Senses Reveal the Hidden Realms Around Us’. Marnie Chesterton was at the ceremony and nabbed Ed as well as Chair of the Judges Alain Goriely to find out what made this book the winner.

An underground river of magma and thousands of tremors have been observed across the Reykjanes peninsula in Iceland. We speak to the scientists monitoring the Fagradalsfjall volcano who explain how this might be ushering in a new era of huge volcanic activity in the country. Sir Chris Whitty, Chief Medical Officer for England and Sir Patrick Vallance, former Chief Scientific Adviser to the UK government are due to appear at the Covid-19 Inquiry next week. It’s the next stage of the public inquiry that began proceedings in July last year. Now it’s focussing on the key questions surrounding how science and the scientific community informed government strategy before, during and after the pandemic. BBC Health Reporter Jim Reed has been attending the inquiry and explains what we know from the evidence that’s been given so far – and what to expect next week. David Quammen discusses his book ‘Breathless: The Scientific Race to Defeat a Deadly Virus’. It's a thriller-style narrative revealing how scientists responded to the coronavirus pandemic. It’s our final shortlisted book for the Royal Society Science Book Prize. The winner will be announced next week.

Professor Saleemul Huq, director of the International Centre for Climate Change and Development in Bangladesh, has died. He was instrumental in pushing for a loss and damages fund for vulnerable countries affected by climate change. Last year’s COP27 climate conference made a pledge to set up this fund. But, as yet, there is not one in place. Marnie Chesterton speaks to BBC climate reporter Esme Stallard about Professor Huq’s legacy, and where the money will come from for a loss and damages fund. We also hear about an unusual snail that’s looking for love, with the help of matchmaking academic Dr Angus Davison. He’s hoping to find a suitor for the mollusc. Marnie talks to Lev Parikian, author of Taking Flight: The Evolutionary Story of Life on the Wing, which has been shortlisted for this year’s Royal Society Trivedi Science Book Prize. Geneticist, Professor Giles Yeo, who recently cycled from Land’s End to John O’Groats with two glucose monitors attached to his arms, gives us an update on his research.

PFAS chemicals, also known as forever chemicals, don’t break down in the environment. They can accumulate in the body and are found to have an array of harmful effects on human health. A major mapping project has revealed worryingly high levels of PFAS across thousands of sites in the UK. Experts are concerned that not enough is being done to reduce these chemicals from drinking water. They’re urging the government to re-evaluate current regulation. This week we dive into the properties of these chemicals: how dangerous are they and what can be done to protect public health? Professor Crispin Halsall, an environmental chemist from Lancaster University, tells us more. As charges are brought against four people for stealing and selling on US$1 million of dinosaur bones, we find out about the illegal – and legal – trade in fossils from palaeontologist Professor Steve Brusatte. New research has discovered the Moon is 40 million years older than we previously thought. Professor Sara Russell, a cosmic mineralogist and planetary scientist from the Natural History Museum, tells us more. And is there something we can we learn from animals about how to age better? Nicklas Brendborg discusses his book, Jellyfish Age Backwards: Nature’s Secrets to Longevity, which has been shortlisted for the Royal Society Trivedi Science Book Prize.

White phosphorous is an incendiary material and if it were to be used in any built-up civilian areas, the practice would violate international law. We find out what makes white phosphorus so dangerous, and we ask how easy is it to identify? Andrea Sella, professor of chemistry at University College London, grants access to his laboratory and conducts an experiment with this highly flammable and volatile substance. Whole words and phrases from crushed and carbonised scrolls can be read for the first time in almost two thousand years. The documents, uncovered from Herculaneum, an ancient Roman town close to Pompeii which was buried under volcanic ash, have been made legible thanks to 3D scans and artificial intelligence. Dr. Federica Nicolardi, a papyrologist at the University of Naples, tells us more about this exciting discovery. Kate Zernike discusses her book The Exceptions, which tells the story of a group of 16 women who used their scientific know-how to inspire radical change. It’s been shortlisted for this year’s Royal Society Science Book Prize. And finally, this month marks exactly a year since beavers became a protected species in England. BBC Inside Science goes to Devon in search of these charismatic animals and we ask what effect they have been having on the countryside.

A paper recently published in the journal Nature claimed that assembly theory could help explain and quantify selection and evolution. But what exactly is assembly theory? In this episode Marnie Chesterton speaks to science writer Philip Ball and zoologist and writer Professor Matthew Cobb. They dig into the science behind this tricky concept and figure out why it makes people so angry. A sample recovered by NASA from the Bennu asteroid hurtled back to earth recently. This week we saw what’s been retrieved from 200 million miles away. Studies on the dust and rock are just getting underway. Professor Tom Zega, one of the mission scientists, reveals why this sample will be important for many years to come. We also hear from Ed Yong who has been shortlisted for the Royal Society Trivedi Science Book Prize. He tells us about his book, An Immense World, where he encourages us to think beyond the confines of our fleshy bodies. People experience the world in many different ways. It all comes down to perception. We speak to Professor Fiona Macpherson who, along with neuroscientist Professor Anil Seth, are co-leads of The Perception Census which aims to document the differences. Fiona reveals how this could help shine a light on consciousness and what it means to be human. The census closes at the end of the month and everyone’s welcome.

UK Prime Minister Rishi Sunak gave a hastily arranged press conference this week in which he confirmed he would be rowing back on some previously made government commitments regarding net zero - the point at which we remove as much carbon from the atmosphere as we put in. The reaction has been mixed, ranging from endorsements from fellow politicians in the Conservative Party to criticism from opposition parties and environmental groups. The business community is also split. So why has Mr Sunak changed his policies on climate change - and why now? Gaia Vince speaks to Ian Dunt, editor of politics.co.uk We hear about an astonishing finding by archaeologists who have discovered expertly manufactured interlocking wooden structural parts that are half a million years old. What do they tell us about our early human ancestors in Africa? Gaia speaks to Professor of Archaeology Laurence Barham and Professor of Geography Geoff Duller about their extraordinary discovery. Approximately two billion tonnes of dust is lifted into the Earth’s atmosphere each year and it is both dangerous to human life and essential to the oxidisation of our oceans and rivers. We relentlessly attempt to rid our homes of dust but it always seems to come back. Why do we hardly ever discuss dust? A new book by Jay Owens, ‘Dust: The Modern World in a Trillion Particles’ does just that. Jay talks to Gaia about why we should we be as fascinated as she is by tiny airborne particles. As we emit CO2 into the atmosphere, a significant amount - around a third - is taken in by the oceans. With growing interest in carbon removal interventions, ocean scientist Dr David T. Ho tells Gaia about undertaking an exciting experiment. Listen to this bonus content in the podcast.

In 2015 the UN adopted 17 sustainable development goals aiming to end poverty, protect the planet and ensure people everywhere enjoy peace and prosperity by 2030. Ahead of a summit next week in New York marking the half way point, presenter Gaia Vince speaks to Saleemul Huq, director of the International Centre for Climate Change and Development in Bangladesh, and Olive Heffernan, a science author and journalist focused on oceans and climate to find out how the world is doing. In July, a new chair was elected to the Intergovernmental Panel on Climate Change which is the United Nations body for assessing the science related to climate change. Professor Jim Skea is a leading figure in the global push to decarbonise, adapt and innovate our way to net zero, and previously led Scotland’s Just Transition Commission. He speaks to Gaia about his new role and the importance of the IPCC. And this week we mark the death of renowned embryologist Professor Sir Ian Wilmut, who led the team that created Dolly the sheep in 1996. Gaia is joined by Roger Highfield, Science Director of the Science Museum Group, to discuss the scientific and cultural impact of the world’s first cloned mammal from an adult animal cell.

Humans have introduced more than 37,000 alien species to places they do not naturally occur. A report launched this week by the Intergovernmental Platform on Biodiversity and Ecosystem Services revealed the shocking extent of the damage. Gaia Vince speaks to one of the report’s chairs, Helen Roy. Also this week, the UK has now rejoined Horizon Europe, the EU’s £85bn flagship research funding programme. Gaia caught up with the Royal Society’s vice-president Linda Partridge to find out what this means. Early this week, the Indian space agency, ISRO, launched its solar mission to study space weather. But in addition, its lunar mission, Chandrayaan-3, also powered down. Gaia speaks to Mahesh Anand, a planetary scientist at the Open University, to find out more about India’s space ambitions. Meanwhile, here on Earth, many of us have been sweltering in heatwave conditions and communicating weather dangers have become a key focus for forecasters. Helen Roberts, the Met Office’s first ever sociometeorologist, explores how cognitive biases affect our responses to warnings.

Extreme weather is forcing communities to leave their homes and it's becoming a bigger and bigger issue. What can we do about it? In this edition of BBC Inside Science, Gaia Vince and her guests discuss what climate displacement means for people all over the world. We hear from Diwigdi Valiente, a member of the Guna Yala people of the San Blas Islands in Panama, where whole communities have already begun to evacuate. Closer to home the experts consider the impact of rising sea levels on British coastal communities. Guests are: Richard Betts, head of climate impacts at the UK Met Office and a professor at the University of Exeter; Lucy Easthope, professor in practice of risk and hazard at the University of Durham and a leading adviser on emergency planning and disaster recovery; Professor Guillermo Rein, an expert in fire science at Imperial College London; and Michael Szoenyi, head of flood resilience at Zurich Insurance. He explains why climate change has become such an important factor for business and individuals planning for the future – and why it’s essential we don’t leave big decisions about where we should live to the last minute. Presenter: Gaia Vince Producer: Clem Hitchcock Content Producer: Alice Lipscombe-Southwell Editor: Richard Collings

River health has captured the public imagination, particularly as overspills from sewers have been getting more attention in the media. But the condition of a river is so much more complicated than what flows into it from our water treatment systems. Agriculture, roads, how we use our drains, what we buy and even the medicines and drugs we take can all have an impact on our rivers and the plants and animals that call them home. So how are UK rivers doing? And what needs to happen to help those waterways that are drowning in pollution? Joining the BBC's Marnie Chesterton on stage at Green Man Festival in Wales to discuss all this is: Dave Johnston, team leader of environmental reporting at Natural Resources Wales, whose responsibility it is to monitor Welsh rivers. Joanne Cable, head of organisms and environment division at Cardiff University, whose focus is on biodiversity and what we at home can do to support our rivers. Simon Evans, chief executive of The Wye and Usk Foundation, who runs citizen science projects to support these two rivers local to the festival. Christian Dunn, wetland biologist at Bangor University, who is keen to explain the power of wetlands and has also done some surprising research into the river near Glastonbury Festival.

Two plucky spacecraft, one Russian and one Indian, are currently blasting towards the Moon’s South Pole. Both Russia’s Luna-25 and India’s Chandrayaan-3 are due to touch down next week. They’re heading to that particular region of the Moon in order to hunt for water, the presence of which could have huge implications for our further exploration of the Solar System. Victoria Gill talks to Dr Becky Smethurst, an astrophysicist at the University of Oxford, to find out more. Victoria then heads to the Lake District to witness the release of water voles into the ecosystem. Next up, Professor Lewis Griffin, a computer scientist from University College London, tells us how bad we are at distinguishing between real and deepfake voices. He then reveals what implications this might have for scams. Finally, Dr Helen Pilcher tells us all about the intriguing ways that animals can bend time. You can find out more in her book, How Nature Keeps Time. Presenter: Victoria Gill Producer: Hannah Robins Content producer: Alice Lipscombe-Southwell Research: Patrick Hughes Editor: Richard Collings

After decades of exploitation, time is running out for the Amazon rainforest. Eight South American nations came together this week for the first time in 14 years in an attempt to draw up a plan for a more sustainable future. The BBC’s South America correspondent Katy Watson sends us an update on the summit from Belém, Brazil. We also hear from Brazilian scientist Joice Ferreira who tells us why the Amazon is so important for the entire planet. Next up Victoria Gill finds out more about how British Sign Language is adding key scientific concepts to its dictionary in order to open up science communication to a broader community of people. There are still many words and phrases that have not yet been ‘signed’. Now did you know that the inhalers used by asthmatics emit a tiny amount of greenhouse gas with every puff? Victoria speaks to Dr Veena Aggarwal, a GP registrar and former member of Greener NHS, about whether the government’s new plan for environmentally friendly inhalers will help. Finally Victoria catches up with palaeoanthropologist Lee Berger. He’s written a book that tells a harrowing tale about his trip into a labyrinth of underground tunnels to find out more about an ancient human-like creature called Homo naledi. Presenter: Victoria Gill Producers: Hannah Robins and Harrison Lewis Content producer: Alice Lipscombe-Southwell Research: Patrick Hughes Editor: Richard Collings

This week the UK government announced that around 100 new oil and gas licences for the North Sea will be issued. At the same time the Prime Minister said the government would back two new carbon capture and storage plants, one in Aberdeenshire and one in the Humber. Victoria Gill speaks to Angela Knight, former chief executive of Energy UK, about what this decision means for the UK’s aim of reaching net zero carbon emissions by 2050. She then discovers more about the capabilities of carbon capture and storage from Paul Fennell, a professor of clean energy at Imperial College London. Next Victoria travels to the sunnier shores of Spain where orcas have been ramming fishing boats. She speaks to one of the sailors who witnessed an attack. To find out more about the orcas’ behaviour, she interviews Dr Luke Rendell, a whale and dolphin expert from the University of St Andrews. We then move to Skomer, off the coast of West Wales. This important seabird colony has recently recorded an avian flu outbreak. Reporter Roland Pease speaks to Lisa Morgan from the Wildlife Trust for South and West Wales. To finish the show Dr Stuart Farrimond is back with the final instalment of his science of gardening series. Presenter: Victoria Gill Producers: Alice Lipscombe-Southwell, Hannah Robins Research: Patrick Hughes Editor: Richard Collings

We're in the heart of summer in Europe, where extreme heat has spiralled into out-of-control wildfires across the Mediterranean, leading thousands to flee their homes. Previously on Inside Science we've looked at how and why temperatures are soaring across the globe. Now we're homing in on one of the most visible effects of that. First, BBC climate and science reporter Georgina Rannard paints a picture of the link between these fires and climate change. Next up we hear from Professor Stefan Doerr, director of the Centre for Wildfire Research at Swansea University, on whether Europe is prepared for a future where these blazes are more frequent and intense. Another effect of climate change you might have heard about this week is the potential collapse of the Gulf Stream. Georgina explains why leading researchers have reservations about the science behind that claim. We investigate a sometimes overlooked and under-reported source of pollution: particles from vehicle tyres. Dr Marc Masen from Imperial College London tells us about the impact they’re having on our health. And pollution from tyres is affecting flora and fauna too. Dr Paul Donald, senior researcher at Birdlife International, explains how vehicles on our roads have impacted wildlife in the environment. Finally, from four wheels to two wheels! Geneticist and body weight scientist Dr Giles Yeo is cycling from Land's End to John O'Groats with two glucose monitors on his arm. He tells us what he's hoping to learn. Presenter: Marnie Chesterton Producer: Hannah Fisher Content producer: Alice Lipscombe-Southwell Research: Patrick Hughes Editor: Richard Collings

This week China hit a record high temperature, a scorching 52.2°C, while Death Valley in California measured 53.9°C. Elsewhere, Europe has been battling searing heat and raging wildfires. In previous editions of Inside Science we’ve explored the effects of heat on our health. This week we’ve zoomed out to get a wider perspective on the impacts of soaring temperatures. First up, Rebecca Tobi from the Food Foundation reveals how this weather will impact the range of foods we are used to seeing on supermarket shelves. Next we hear from Hayley Fowler, professor of climate change impacts at Newcastle University. She explains how the jet stream – which plays a large role in the UK’s weather – is affecting extreme weather patterns. Another country experiencing particularly extreme weather at the moment is China. BBC correspondent in Hong Kong, Danny Vincent, tells us how record temperatures could have wide-ranging effects beyond China’s borders. Changing heat patterns could even unlock new habitats for wildlife. Jo Lines, professor of malaria and vector biology at the London School of Hygiene & Tropical Medicine, says that we need to be aware of mosquito-borne diseases that could take hold in Europe. Then it’s off to Reading University, where reporter Harrison Lewis chats to meteorologist Dr Rob Thompson and senior researcher Dr Natalie Harvey, to find out more about how weather balloons can help with storm forecasting. Finally, we’re heading back to Trowbridge, near Bath, where Dr Stuart Farrimond explains exactly how our gardens can help in the battle against climate change. Presenter: Marnie Chesterton Producer: Harrison Lewis Content producer: Alice Lipscombe-Southwell Assistant producer: Robbie Wojciechowski Editor: Richard Collings

The Threads social media app launched on 5th July. Instagram users were able to sign up with just a few clicks. It joins a plethora of other social media apps like Snapchat, Twitter and TikTok, all of which are readily accessible on our phones. With all these apps at our fingertips, it’s never been easier for us to discover new people to follow, keep in touch with our friends and stay up to date with the latest news about our favourite celebrities. But Professor Devi Sridhar, the chair of global public health at the University of Edinburgh, is concerned about the harmful effect that all these apps could potentially be having on the health of young people. She talks to Marnie Chesterton about why they should be better regulated in order to protect our children. Marnie is then joined by Professor Andrew Przybylski from the University of Oxford who says that more studies need to be carried out. Next up we find out more about phages – ‘good’ viruses that infect and destroy bacteria and could hold the key to fighting disease. Tom Ireland, author of a new book, The Good Virus, tells Marnie about the history of phages and their potentially exciting future. This week the European Court of Human Rights ruled in favour of middle-distance runner and Olympic champion Caster Semenya in a case related to testosterone levels in female athletes. Marnie speaks to developmental biologist Dr Emma Hilton about what causes differences in sexual development and the impact they can have. We also hear from Dr Stuart Farrimond who explains how the microclimates in your garden can affect the plants you can grow. Presenter: Marnie Chesterton Producer: Harrison Lewis Content producer: Alice Lipscombe-Southwell Assistant producer: Robbie Wojciechowski Editor: Richard Collings

A rocket launch, super-massive black holes and ghost particles! This past week’s scientific findings are testament to how hard-at-work cosmologists and physicists have been seeking out the fundamental building blocks of our universe and the rules that govern it. Professor of Cosmology at UCL, Andrew Pontzen, joins Marnie Chesterton to discuss the lot of them. Euclid took to the stars on Saturday, carrying a wide-angle space telescope that promises the opportunity to create a far larger and accurate 3D map of the universe to anything ever seen before. Gravitational waves detected by the North American Nanohertz Observatory for Gravitational Waves (NANOgrav) provide insight into the role black holes play in galaxy formation. And neutrinos recorded in the remote ices of Antarctica have been detected from the centre of our Milky Way. Dr Stuart Farrimond also joins us for the next few weeks with his pitch on the science of gardening. He’ll be digging up facts and tips that will help make the most out of summer blooms. This week Stu unearths how the pH of your soil could be hindering the flowerbeds. And visit a Welsh quarry with reporter Ella Hubber to hear how a mere 462 million years ago new species were exploding onto the scene. Palaeontologists Dr Joe Botting and Dr Lucy Muir stumbled across the most abundant and rare deposit of soft bodied fossils on record, scoring an archaeological jackpot! Presenter: Marnie Chesterton Producer: Harrison Lewis Content producer: Alice Lipscombe-Southwell Assistant producer: Robbie Wojciechowski Editor: Richard Collings

Last summer saw intense heatwaves across the world. And already this year, global air, surface and sea temperatures have hit the highest levels on record. China, India and the US are currently experiencing heatwaves. In June, the UK’s Met Office released a health warning because of the high temperatures. In this episode Gaia Vince investigates what causes heatwaves and how hotter weather impacts our health. She finds out how we can prepare ourselves as the temperatures rise. Gaia is joined by Peter Stott at the Met Office Centre for Climate Prediction, who reveals more about the forecast and what causes heatwaves. She also speaks to Bob Ward, policy director at the Grantham Research Institute on Climate and the Environment, who gives us the lowdown on the UK’s heat health warning system and says what the future could look like if we continue to miss climate targets. In addition, Dann Mitchell, professor of climate science at the University of Bristol, discusses the health impacts of extreme heat. Guillermo Rein, professor of fire science at Imperial College London, explains what sparks wildfires and how they spread. Elsewhere, Germany has launched a high-tech heat health warning system to warn people when the temperatures are rocketing. Gaia speaks to Andreas Matzarakis, from Albert Ludwig University in Freiburg, who developed the system. Presenter: Gaia Vince Producer: Harrison Lewis Content Producer: Alice Lipscombe-Southwell Assistant Producer: Robbie Wojciechowski Editor: Richard Collings

Scientists, conservationists and other researchers are using audio soundscapes in innovative ways to record the natural world in rich detail and help develop strategies to preserve it. Gaia Vince visits the Dear Earth exhibition at London’s Southbank Centre where she interacts with the ‘Tell It To The Birds’ artwork by Jenny Kendler. This piece transforms spoken word into birdsong, which Jenny hopes will help raise awareness of threatened species. She is joined by Dr Patricia Brekke from the Zoological Society of London who reveals more about the threats faced by birds. We then visit the Knepp Estate to meet ecologist Penny Green, who reveals more about the value of audio for her work. Gaia then speaks to Dr Alice Eldridge, an acoustics expert from the University of Sussex, who has spearheaded the Wilding Radio project at the Knepp Estate in Sussex. She was curious to find out whether the sounds in the environment would change following the introduction of beavers to the estate. In collaboration with arts cooperative Soundcamp, she built high-quality, solar-powered equipment to continuously broadcast the soundscape from above and below the water. While we can record animals which we currently share the world with, what about those that have been lost forever? Cheryl Tipp, the British Library’s curator of wildlife and environmental sounds, looks after the library’s audio collection of more than 250,000 species and habitat recordings. She shares the heartbreaking tale of a now-extinct bird and explains why sound is such a valuable resource. Finally, Dr Tim Lamont, a marine biologist from Lancaster University, tells us why a degraded coral reef sounds different from a healthy one. He explains how broadcasting the sounds of a healthy reef can help attract more marine wildlife to an area. Presenter: Gaia Vince Producer: Hannah Fisher Content Producer: Alice Lipscombe-Southwell Editor: Richard Collings

On Tuesday, the United Nations reported that the breach of the Nova Kakhovka dam on the Dnipro River in Ukraine will impact heavily on global food security, causing a rise in food prices and leaving many without access to clean drinking water. Nine days after the disaster Gaia looks to the future alongside Kira Rudyk, Ukrainian MP who is also leader of the opposition party Golos and Laura Wellesley, senior research fellow in the Environment and Society Programme at Chatham House. Earlier this week the three-year inquiry into COVID began, seeking ‘to examine the UK’s response to and impact of the COVID-19 pandemic and learn lessons for the future.’ Eyes are on the inquiry from many angles. Inside Science looks at what scientists hope to contribute and learn from it, with author and broadcaster Philip Ball. Also, a spike in North Atlantic sea temperatures has sparked concern among scientists. Richard Betts, head of climate impacts at the Met Office, talks through the factors that have coincided to form the anomaly. Presenter: Gaia Vince Producer: Harrison Lewis Assistant producer: Robbie Wojciechowski Editor: Richard Collings

For World Ocean Day, Gaia Vince finds out how the planet’s seas could help us to generate clean power, capture CO2 and feed the world. Gaia is joined in the studio by science journalist and marine biologist Olive Heffernan. She dives into the controversy regarding the potential of mining in deep oceans and discusses whether the seas could become the location for Industrial Revolution 2.0. We’re used to seeing seaweed wrapped around our sushi rolls but it’s so much more than that. As well as being a tasty addition to what we eat, seaweed plays a vital role in absorbing CO2. Gaia speaks to Vincent Doumeizel, a senior adviser on oceans to the UN Global Compact; he’s also the food programme director at the UK-based charity Lloyd’s Register Foundation. He’s confident that seaweed could enable us to sustainably feed a growing global population in the coming decades. Phytoplankton – microscopic species of algae that exist on the surface of the sea – also absorb huge amounts of carbon from the atmosphere. Sir David King, founder and chair of the Climate Crisis Advisory Group and former chief scientific adviser to the UK Government has the radical idea that artificial whale poo could boost phytoplankton growth, leading to an increase in fish stocks and, consequently, improved biodiversity in the oceans. He tells Gaia about his project and the potential it has for carbon capture. When we think of energy generation from the oceans, we tend to think of offshore technology such as wind turbines. But what about generating electricity using the water itself? Gaia speaks to Eco Wave Power’s Inna Braverman who reveals how her project harnesses the power of the waves by attaching to existing coastal structures such as piers and jetties, to provide a source of clean, renewable energy. Presenter: Gaia Vince Producer: Hannah Fisher Content Producer: Alice Lipscombe-Southwell Editor: Richard Collings

In the headlines this week eminent tech experts and public figures signed an open letter that read “Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war.” One of the signatories was Geoffrey Hinton, the so-called ‘godfather of AI’. He’s become so concerned about the risks associated with artificial intelligence that he recently decided to quit his job at Google, where he had worked for more than a decade. But are these concerns justified, or is it overblown scaremongering? And should we start prepping for a Terminator-style takeover? To get the answers, presenter Gareth Mitchell is joined by computational linguist Prof Emily M. Bender from the University of Washington along with Dr Stephen Cave, Director at the Leverhulme Centre for the Future of Intelligence (CFI). Next up, we hear from Prof Carl Sayer at UCL, along with Dr Cicely Marshall and Dr Matthew Wilkinson from the University of Cambridge, to dig into the science behind wildflower meadows and whether they can boost biodiversity and even help ease climate change. Finally, have you heard about Balto the sled dog? He was part of a life-saving mission in the 1920s and now he has the chance to be a hero once more. His DNA has been studied by the Zoonomia project, which is using databases of genomes from hundreds of mammals to build a better picture of evolution. This data could then be used help identify those animals that are at the greatest risk of extinction. Presenter: Gareth Mitchell Producer: Harrison Lewis Content Producers: Ella Hubber and Alice Lipscombe-Southwell Editor: Richard Collings

This week, we hear from the University of Florida’s Dr David Duffy. He heads up a team of researchers who are studying sea turtles. In order to track the animals and their diseases, the scientists devised a method of collecting fragments of DNA from tanks at the university’s turtle hospital, as well as from sand and water in the local environment. While they found plenty of turtle DNA, they were surprised to uncover large amounts of high-quality human eDNA. Duffy tells us all about the study and his surprising findings, but also highlights the ethical problems this could raise. We are then joined by Dr Matt Clark from the Natural History Museum, and Sir Jonathan Montgomery from University College London, to discuss the ins and outs of eDNA – how it can be beneficial for conservation, forensics and healthcare, but could also be problematic from a privacy perspective. Muriel Rabone and Dr Adrian Glover from the Natural History Museum have compiled an extensive checklist of all the species present in the remote Clarion-Clipperton Zone, which is an area twice the size of India, five kilometres deep in the Pacific Ocean. While you might expect this part of the sea to be devoid of life, the organisms that live there are surprisingly diverse, and we still know little about them. But the region is also chock-full of in-demand rare-earth metals. And we are joined by Dr Katie King to talk over some of her favourite science stories of the week, followed up by Helen Keen, who gets the kettle on to reveal more about the surprising physics behind a cup of coffee. Milk and two sugars for us, please. Presenter: Gareth Mitchell Producer: Hannah Fisher Content Producer: Alice Lipscombe-Southwell

The Royal Society is the oldest scientific academy in the world. Since being established in 1660, it has painstakingly archived thousands of papers, letters, manuscripts and illustrations from some of science’s most enquiring minds. In this episode, Victoria Gill takes a trip to the society to pore over some of the most intriguing artefacts within its vaults. While there, she finds out more about the formation of the Royal Society and how science has been shaped over the centuries. Along the way, she considers the role of women in science, and asks whether their contributions have been historically overlooked. She is joined by the Royal Society’s Louisiane Ferlier and Keith Moore, along with Prof Uta Frith, a Royal Society Fellow and psychologist, and Dr Stephen Webster, a senior lecturer in science communication at Imperial College London. As part of its Science in the Making project, the Royal Society is currently digitising all of its collections, for everyone to browse through and enjoy. You can find out more on the Royal Society website. Presenter: Victoria Gill Producers: Harrison Lewis, Hannah Fisher Content Producer: Alice Lipscombe-Southwell

Natural disasters such as earthquakes, tsunamis, volcanoes and hurricanes all have the power to cause deadly destruction. One event can lead to another, causing a chain reaction of devastation that can take years to rebuild from. But do all natural events have to turn into a disaster? Is there anything we can do to mitigate their impacts? Gaia Vince speaks to Anastasios Sextos, Professor of Earthquake Engineering at the University of Bristol to find out how we can engineer buildings to withstand earthquakes, and Bruce Malamud, Executive Director of the Institute of Hazard Risk and Resilience at Durham University, to learn how we can build models to forecast the risk of a natural disaster occurring. Lucy Easthope is a leading advisor on emergency planning and disaster recovery and a Professor in Hazard and Risk at Durham University. She joins Gaia in the studio to discuss her experience of being one of the first responders to disasters and how in fact, the way they unfold is more predictable than we might think. Ilan Kelman, Professor of Disasters and Health at UCL, also joins them to discuss the importance of social resilience, long-term planning and effective alert communication in managing and mitigating the aftermath of these events. Presenter: Gaia Vince Producer: Hannah Fisher

In 2020, the UK government committed to protecting at least 30% of land and sea for nature by 2030. Step seven years into the future with Gaia. The UK has achieved its biodiversity goal, but what does wild Britain look like? Richard Benwell, CEO of wildlife and Countryside Link, Meredith Whitten, a researcher and urban environment planner at LSE, Hugo Tagholm, CEO of Oceana and George Monbiot, an environmental writer whose book Regenesis explores sustainable agriculture, describe this radical new world. Presenter: Gaia Vince Producer: Harrison Lewis

James Watson and Francis Crick, who detailed the double-helix structure of DNA in 1953, are perhaps two of the most iconic scientists of the 20th Century. Yet the story of how they made their incredible discovery is perhaps equally famous, with a notorious narrative suggesting that they only identified the structure after taking the work of Rosalind Franklin and using it without her permission. Now, 70 years after the discovery of DNA’s structure, it is perhaps time to rewrite the tale. New evidence has now been unearthed, in the form of an overlooked news article and an unpublished letter, that shows that Franklin was truly an equal contributor to the discovery, and Watson and Crick were not as malicious as previously assumed. Together with Matthew Cobb of the University of Manchester, Nathaniel Comfort from Johns Hopkins University, and Angela Creager of Princeton University, Gaia Vince discusses this tantalising tale and finds out more about how this discovery could bring a whole new twist to the story of DNA. Presenter: Gaia Vince Producer: Harrison Lewis Assistant Producer: Jonathan Blackwell

Whilst the globe struggles to shift to green sustainable energy sources, one industry has its sights set solely on the stars. Space X just launched the biggest rocket the world’s ever seen, and it won’t be their last even if it did end its test flight with a bang. As we enter a new golden age of space travel, Vic asks Associate Professor in Physical Geography Dr Eloise Marais if we are paying enough attention to the environmental impacts posed by a rapidly growing space industry. Have viruses, bacteria, and microorganisms influenced humanity more than we know? Author of new book, Pathogenesis: How Germs Made History, Dr Jonathan Kennedy discusses how germs and disease have shaped human evolution, history and culture and what we can learn from the COVID pandemic. And from unconventional life in space to psychoactive spinning apes, Vic and BBC Climate Reporter Georgina Rannard bring you the best scientific stories from the past couple of weeks. Presenter: Victoria Gill Producer: Harrison Lewis Content Producer: Ella Hubber BBC Inside Science is produced in collaboration with the Open University.

When was the last time you had to use your negotiating skills? Did you walk away satisfied? This week junior doctors are half way through their 4 day walkout, with senior NHS figures suggesting the cancellation of between 250,000 and 350,000 appointments/operations. Victoria Gill is preparing to debate her way through the science of disagreement and identify what qualities make for the perfect negotiator. Associate Professor Sunny Lee, Deputy Director of Equality, Diversity, and Inclusion at University College London helps guide Victoria through the basic building blocks that help resolve conflict, with expert commentary from Camilla Born peeking behind the curtain of COP26, and finally negotiating with elephants? Dr Josh Plotnik at City University of New York suggests that some animals may be actively seeking out conflict with humans. Presenter: Victoria Gill Producer: Harrison Lewis

In this special edition of Inside Science, Vic Gill prepares to rummage through our rubbish, to peek behind the curtain of the UK's recycling habits and see how well prepared we are as a nation to further our efforts of sustainable waste management. Presenter: Vic Gill Producer: Emily Bird

Far away and not enough, those are criticisms of the government’s latest net zero initiative – a plan to reduce emissions . We ask Jim Watson Professor of Energy Policy and Director of the UCL Institute for Sustainable Resources for his assessment. And there’s money to be made from private health testing, the growth of Covid testing has been followed by an upsurge in private screening for cancer in particular, but how useful is it really? BBC Health correspondent Matthew Hill takes a look. Every cell in out body carries an electrical charge. In her new book, We Are Electric: The New Science of Our Body’s Electrome, Sally Adee discusses how this facet might be harnessed for the detection of illnesses, medical treatments and whether it will allow us to develop hidden powers. The World Wood Web is a concept showing how trees communicate with each other through an underground fungal network. The idea was first proposed by Suzanne Simard, Now professor of Forest Ecology at the University of British Columbia, who tells us how she came up with the concept and about her work on the hidden relationships of trees.

Data collated from swab samples taken in Wuhan’s market in the early days of the Covid pandemic suggest animals sold in the market were carrying the virus at the time. It’s the strongest evidence yet for an intermediate species – one which passed the virus on to humans after becoming infected by bats carrying the virus. Dr Florence Debarre from the Institute of ecology and environmental sciences, in Paris and Professor Eddie Holmes from Sydney University discuss the findings. Beethoven’s genome has been reconstructed from samples of his hair. It reveals some of his medical history, but also unexpected findings on his paternity. We discuss the ethics of such genetic analysis with Tom Booth who studies ancient DNA at the Francis Crick institute. And microbes may help us survive and thrive in space according to Astrobiologist Rosa Santomartino, not only that but their recycling capabilities could also help us on earth

Researchers from London’s Francis Crick Institute have found a type of artificial sweetener is able to dampen down immune system responses - at least in mice. Karen Vousden and Fabio Zani tell us about the implications. And Ronan McCarthy from Brunel University has found a range of different artificial sweeteners have antibacterial properties. We discuss the connections between these two areas of research and the prospect of developing drug treatments from artificial sweeteners. Penny Johnes from Bristol University discusses the use of phosphorus in agriculture, it’s a key component of fertilisers, but global supplies may run out in a few years, despite this overuse of phosphorus in agriculture is also creating problems. And Chat GPT has had a makeover, a new version of the chatbot was rolled out this week. Chatbots seem to be getting a lot of press at the moment, but are they really something we will all be using in the future? Technologist and composer LJ Rich who works with the UN on artificial intelligence gives us her analysis. BBC Inside Science is produced in collaboration with the Open University.

The government has launched a new 10-point plan designed, it said to “cement the UK’s place as a global science and technology superpower”. We speak with Sir Paul Nurse, director of the Francis Crick Institute, for his take on the government's plan and the findings of his own review of the UK’s research landscape. In 1963, in a now famous speech at the Labour Party conference in Scarborough, Labour leader and soon to be Prime Minister Harold Wilson promised a new Britain would be forged in the “white heat" of a "scientific revolution". Nick Thomas Symonds, Labour MP and political biographer, discusses how that idea was put into action. Scientists in Bristol have published a detailed "future flood map" of Britain - simulating the impacts of flooding as climate change takes its toll. Paul Bates from Bristol University explains how the new flood risk maps give a level of detail that could help people to plan and adapt. Vic Gill visits the Calder Valley in West Yorkshire, a place that’s suffered repeated flooding in recent years, where the community is taking matters into its own hands. New fossil findings from China have led scientists to re-evaluate their classification of tiny tentacled sea creatures from half a billion years ago and declare that they are in fact seaweeds says Martin Smith, a paleobiologist from The University of Durham. And this re-classification isn't unusual, fossils are constantly re-examined in light of new evidence and insights. Susie Maidment a paleobiologist at the Natural History Museum takes us through some of her favourite contentious fossils. Presenter: Victoria Gill Producers: Julian Siddle and Emily Bird BBC Inside Science is produced in collaboration with the Open University

Science writer Philip Ball has followed the relationship between government and its scientific advisors throughout the pandemic. He discusses the role of scientific advisors in the light of conflicting information following the leak of a number of former Health Minister Matt Hancock’s WhatsApp messages. Phil tells us why he believes greater transpearency is needed around the advice offered to government. The head of the US FBI has suggested the Covid 19 pandemic may have been started through a leak from a laboratory. No evidence has been offered. The ‘lab leak ‘ theory is the counter idea to Covid having a natural origin. We hear from three scientists who have been to China to investigate different aspects of the virus origins story. Journalist and microbiologist Jane Qui visited the Wuhan Institute of Virology – the lab at the centre of the lab leak theory. Marion Koopmans from Erasmus University in Rotterdam was a member of the WHO mission to China to investigate the origins of Covid 19. And Eddie Holmes from the University of Sydney visited the market in Wuhan, the epicentre of the outbreak. Besides inflating party balloons helium gas has a vast range of industrial uses, particularly as a coolant. There’s a world shortage, and helium is only extracted with fossil fuels such as coal and methane gas. Earth scientist Anran Cheng at the University of Oxford has developed a method to look for helium deposits without the fossil fuel connection. And ever wondered how heavy all the animals in the world might be ? We have the answer thanks to Ron Milo and Lior Greenspoon from the Weizmann Institute of Science in Israel. BBC Inside Science is produced in partnership with the Open University. Presenter: Victoria Gill Producer: Julian Siddle

Sea ice coverage hit a recording-breaking low in the Antarctic this week, but what does this mean for the rest of the world? Why is the region so difficult to predict? And what could further changes in climate mean for the South Pole? Often the Arctic dominates conversations around polar warming but this week, with the help of climate modelling expert Tamsin Edwards, Kings College London, we’ll be tackling these questions and more. We’ll hear from British Antarctic Survey researcher Nadia Frontier, a marine biologist spending the summer at Rothera research base in the Antarctic. We join her as she traverses snow and ice to study the inhabitants of Adelaide island and the surrounding waters. Rachel Tilling from the Cryospheric Sciences Lab at NASA’s Goddard Space Flight Center helps us explore the continent from a different vantage point, explaining her work using satellite data to understand sea ice thickness. And climate reporter Georgina Rannard takes us through an artistic interpretation of polar sounds, Dr Geraint Rhys Whittaker uses underwater microphones to capture the impact of human activity on polar wildlife. Presenter: Victoria Gill Producers: Julian Siddle and Emily Bird BBC Inside Science is produced in collaboration with The Open University.

Chinese biophysicist He Jiankui caused international outrage when in 2018 when he used the gene-editing tool known as CRISPR Cas-9 to edit the genomes of two human embryos. That experiment, described by the Chinese Academy of Science and Technology described as ‘abominable’, resulted in the birth of twin girls. The experiment also landed Dr He in prison for three years. Now, out of prison and working for a company in Beijing that proclaims to offer “affordable gene therapy” – He Jiankui has been speaking in public. At an open bioethics event at the University of Kent last weekend, organisers invited the scientist to present his research and to face questions about his past experiments and his future plans. We spoke to event organiser Dr Joy Zhang about the reaction to event and to Professor Robin Lovell-Badge at the Crick Institute about the implications of CRISPR-CAS9 technology. A Hippo butchery site reveals that distant human ancestors have been using stone tools far longer than researchers previously thought. This archaeological site in Kenya revealed that ancient hominins Paranthropus have probably been using stone tools to prepare food and weapons since 2.9 million years ago. Professor Tom Plummer at Queens College, City University of New York take us through the discovery and what it reveals about hominin evolution. A study released this week reveals just how much of a burden sons are on killer whale mothers. Michael Wiess, research director at the centre for whale research, fills us in on their findings which are a product of nearly 40 years studying the southern resident Orca population. This long-term Whale census project began in the 70s, championed by researcher Ken Balcomb, who was passionate about understanding and protecting killer whales and who sadly passed away late last year. We hear from Ken and his team out on the water studying the southern residents, more of which can be found in BBC Radio 4 documentary The Whale Menopause.

This week’s programme is a thought experiment: What would the world be like if energy became superabundant and very cheap? Energy is vital for every aspect of our society, and the energy cost of extraction, processing, manufacture and transport is priced into every product we buy. Today’s energy crisis is having a huge impact, from affecting diplomatic relations between nations to the availability of food. How can our energy systems evolve and what could cheap abundant energy mean for us, our relationship to the natural world, and each other? We discuss these issues and more with; Rachel Kyte CMG, Dean of The Fletcher School at Tufts University, who has previously worked for the UN on sustainability issues. Jim Watson, Professor of Energy Policy at UCL. He’s advised government on the low carbon energy transition. And Dr Hannah Richie, Head of Research at Our World in Data, based at Oxford University, who looks at food, agriculture and energy in relation to global development trends. BBC Inside Science is produced in partnership with the Open University.

Defra, the department for Environment, food and Rural affairs, released its latest Environmental Improvement plan this week. Many environmental groups have criticised the plan for having vague commitments, and landowners are asking where the money is going to come from if say farmers are going to move land out of production and into conservation. For a view away from these vested interests we’ve turned to the Office of Environmental protection – the body set up after Britain left the EU to scrutinise government environmental policy. Chief Executive Dame Glenys Stacey, and Chief Insights Officer, Professor Robbie McDonald. Last week the UK passed an emergency exemption allowing sugar beet farmers to use a controversial neonicotinoid pesticide called Thiamethoxam. This is the third year in a row that the exemption has been in place and the decision came just days after the EU banned such exemptions across Europe. A discussion in parliament yesterday saw MPs criticise the move due to the impacts of neonicotinoids on already crashing Bees populations. We spoke to Dr Richard Gill at Imperial College London about exactly how these insecticides impact bees. There are volcanic islands dotted across the globe but exactly what caused their formation and how might they change in the future? Professor Ana Ferreira at University College London is a seismologist leading an ambitious study to measure deep vibrations and disturbances around volcanic islands in the Atlantic Ocean. She told us about the challenges of recording from the ocean floor and the other unexpected disturbances they detected. As humans our eyes are one of our most valuable and expressive social tools. The whites of our eyes or sclera enable us to follow each others gaze and look our for minute changes in mood, a feature that until recently was thought to be unique to humans setting us apart from animals in our ability to communicate. But Anthropologist Aaron Sandel at The University of Texas in Austin has noticed that white sclera is in fact present in one of our closest relatives; the chimpanzee.

What if all schools offered only plant-based options for 3 out of 5 lunches a week? Would that be enough to trigger a broader societal shift to eating less meat, and allow us to meet our sustainability commitments? We’re not talking about making school dinners entirely vegetarian — just 3 lunches a week. We discuss the benefits and practicalities of such a shift with : Tim Lenton, Professor of Climate change at the University of Exeter. Economist Marco Springmann Senior Researcher, Oxford Martin Programme on the Future of Food, University of Oxford. Nutritionist Collete Fox from Proveg international an organisation working directly with schools in the UK to encourage the provision of healthier school meals. And Henry Dimbleby founder of the Leon fast food chain is now an advisor to government, responsible for drawing up national rules on school dinners. We also visit Barrowford primary in Lancashire, which has successfully rolled out more vegetarian school dinners. BBC Inside Science is produced is partnership with the Open University.

Former Energy Minister Chris Skidmore’s report into Net Zero calls for ambitious policies to drive energy transition, framing it as a huge economic opportunity to drive national growth. Using and conserving energy in the home is one theme the report tackles. We discuss home insulation with Colm Britchfield , policy advisor at E3G. His recent report found those in some of the worst housing , in the private rented sector could save hundreds of pounds a year if their homes were properly insulated. But what is the incentive for landlords to pay for insulation? Electric heat pumps have been heralded as an alternative to gas boilers, but they are currently more expensive and finding an installer is not easy. Rebecca Dibb-Simkin from Octopus Energy tells us how they are working to make the technology more available. And what is the role of local authorities in the strive for net zero? We hear from Polly Billington, chief executive of UK 100 – a network of local government leaders committed to sustainability policies. How do you catch a poacher? One way might be through their own mobile phone. Another is using a camera trap which sends a signal to game wardens. These are technologies developed by Tim Van Deursen and Thijs Suijten from Hack the Poacher. And we look at new findings on one of Australia’s Iconic species – Echidnas. Dr Christine Cooper at Cutin University in Western Australia, found this marsupial is actually remarkably heat tolerant, and capable of handling temperatures which were previously thought to be lethal.

ChatGPT (Generative Pre-trained Transformer) is an online conversational chatbot, launched by OpenAI in November 2022. To date it remains an online sensation, allowing users to generate poems, essays, code and images in seconds. But fear bubbles in academic circles that artificial intelligence could promote plagiarism in secondary and tertiary education. Technology writer and broadcaster Bill Thompson, and teacher of 20 years digital philosopher Rebecca Mace from University of West London suggest the news headlines may be sensationalising the impact this chatbot will have on student learning. The 1922 backbench committee on business, energy and industrial strategy is recommending free electricity for locals residing within 1 mile of onshore wind farms. Richard Black, senior associate at Energy and Climate Intelligence Unit, joins Marnie to discuss whether or not there is evidence of residents requiring incentives to accept renewable developments whilst governments strive to increase the implementation of green technologies. Do you tap your toes to Paul Simon or rock out to Led Zeppelin? Even if you have two left feet, your ability to recognise rhythm is unique in the animal kingdom. To help determine the human origins of musical appreciation, Teresa Raimondi and her team at Turin University, have been researching primates. Their singing lar gibbon, appears to share similar traits to us that might shed light on where our ability to keep the beat evolved from. And finally, figures from the water regulator suggest that in England and Wales 1 trillion litres of water was lost last year to leaks. BBC Inside Science presenter, Vic Gill, goes in search of what might be a robotic solution. This programme was made in partnership with the Open University.

The UK's first satellite launch faced several delays in 2022, but Virgin Orbit's Cosmic Girl is prepped for imminent take off. BBC science correspondent Jonathan Amos has been following the activity in Newquay and, alongside Melissa Thorpe head of Spaceport Cornwall, describes the potential this launch has to promote and bolster the UK's space industry. Is laziness a particularly human trait? Apparently not according to Dr Daniella Rabaiotti from the Zoological Society of London. Her research shows many animals engage in behaviour akin to laziness even within groups where others might be very active. There’s evidence for this from animals as diverse as wolves, frogs and pheasants. Dani says it’s a factor worth considering in animal behaviour studies, simply are we biased towards the more active and outgoing animals as they are the ones we tend to see? Victoria Gill speaks to the founder and CEO of Nature Metrics Dr Cat Bruce and Katie Critchlow about the tools they use to help companies measure biodiversity at their worksites. From taking water or soil samples it’s possible to detect the DNA of a multitude of organisms from large animals down to microbes. The technique should help map the biodiversity of a given area and inform decisions on development and conservation. BBC Inside Science is produced in collaboration with the Open University

Nations are racing to protect 30% of the planet by 2030 in an attempt to halt biodiversity loss, but one novel approach may be able to safeguard species under threat of imminent extinction. Vic visited Nature’s Safe in May, a cryogenic biobank, storing the genetic information of at risk species in futuristic biological freezers. But will it serve as a viable tool to bring wildlife back from the brink if the ecosystems in which these animals reside are degraded beyond repair? The Greenland ice sheet is melting, raising global sea level at an alarming rate. Marnie took to the ice with researcher Jason Box in September, and questions how current carbon emissions will influence melting in the future. Gaia revisits UN talks from March that attempted to put in place regulations capable of protecting the marine biodiversity of the high seas. Negotiations were unsuccessful at the time, but further talks have been held since. How much progress has been made? BBC Inside Science is produced in collaboration with the Open University.

How many Scientists does it take to cook Christmas dinner? Marnie seeks help from a food scientist, a geneticist, a doctor and a botanist to create the perfect festive feast.

Base editing is a technique for substituting the building blocks of DNA. It has only been around for a few years, so its use to apparently cure cancer was all the more remarkable, as BBC Health Correspondent James Gallagher tells us. We take a trip down the river Wye with ecologist Steve Ormerod who tells us why the river is a microcosm for some of the global issues being discussed at the UN Biodiversity summit in Montreal. BBC Environment Correspondent Victoria Gill gives us the latest on the state of negotiations there. And the current surge in infections associated with the streptococcus bacteria has led to deaths in a few cases. It is usually a seasonal infection, worse in the spring. We ask microbiologist Dr Claire Turner from Sheffield University why we seem to be seeing a surge of infections now and her research on strep vaccine targets. BBC Inside Science is produced in collaboration with the Open University.

The UN Convention on Biological Diversity summit, currently taking place in Montreal Canada, intends to develop ways of reducing the global loss of biological diversity by drawing up a series of international commitments to help humanity to live more harmoniously with nature. The scientific evidence paints a grim picture of species decline and extinction, pollution and destruction of natural habitats. The aim of the meeting is to find ways to stop and even reverse such decline. We meet leading figures involved in the negotiations, including: Elizabeth Mrema, the Executive Secretary of the UN Convention on Biological Diversity Inger Andersen Executive Director of UN Environment Programme Indigenous leaders Viviana Figueroa and Lakpa Nuri Sherpa And scientists Professor Sandra Diaz from the University of Cordoba Dr Marla Emery Scientific Advisor with the Norwegian Institute for Nature Research.

For a week at the beginning of December 1952, London was under a blanket of deadly smog. As a result, the Clean Air Act came into force a few years later banning smoky sulphurous fuels. However air pollution researchers are now concerned that rising emissions from wood burners may be undoing many of the gains from the Clean Air Act. We hear from Dr Gary Fuller, air pollution scientist at Imperial College London and author of The Invisible Killer, the Rising Global Threat of Air Pollution and How We can Fight Back. We also discuss emissions we can’t see, bacteria and even microplastics which are now present in the air. Catherine Rolph from the Open University tells us where we might find them. And we reveal the winner of the Royal Society Insight Investment Science Book Prize. You can find interviews with all the shortlisted authors in our previous programmes. BBC Inside Science is produced in partnership with the Open University.

The UK has the opportunity to access European science funding. However disagreements over the Northern Ireland protocol are preventing the UK from joining the multi billion pound Horizon Europe project which funds scientific partnerships between European institutions. BBC Science correspondent Pallab Ghosh has been following developments. Spending time in green spaces has been linked to mental and physical health benefits. But just how green is your nearest city centre? New research has ranked urban centres in the UK based on their ‘greenness’ and Jake Robinson, from Flinders University in Australia, revealed who came out on top. We hear about initiatives to enhance ‘greenness’ including the citizen-science led GroundsWell programme with Elly King, from the University of Liverpool, and living walls with Brenda Parker, at UCL. And from the Royal Society science book prize, we’re talking sex and gender with primatologist Frans De Waal whose new book is entitled Different: What Apes Can Teach Us About Gender.

As the COP27 environment summit draws to a close we look at some of the issues still to be resolved. BBC Environment correspondents Victoria Gill and Georgina Rannard join us from the meeting. And we head to the houses of parliament in the company of a group of teenagers who are putting their concerns over climate change to a panel of politicians. Julia Ravey went to meet them. We hear from author Nick Davidson about how the discoveries of 3 unlikely characters in the 19th century formed the basis of geological science. His book The Greywacke is shortlisted for the Royal Society Science Book Prize. And a scientific analysis of the Winchcombe meteorite gives us some clues as to the possible origins of life on earth. Natasha Stephen from Plymouth University is one of the many scientists who analysed the composition of the rock fragments.

One key issue on the agenda at the COP27 environment summit in Egypt is how to fund damage from the effects of man made climate change. Often the effects of climate change are felt the strongest in countries least responsible for creating the emissions. This year we’ve seen a range of extreme weather events including drought and flooding which scientists have attributed to man-made climate change. The idea of providing funding for such human-induced disasters has long been discussed informally at COP summits. Finally the issue is formally on the table. It's fraught with diplomatic difficulties, not least over who should pay and how much. We discuss some of the issues in getting a solution on this initiative known as ‘Loss and Damage’ with contributions from Josh Gabbatiss from the website Carbon Brief, Rachel Kyte, the Dean of Tufts University, Linnéa Norlander Assistant Professor of human rights and sustainability at the University of Copenhagen and Hyacinthe Niyitegeka, coordinator of the Loss and Damage Coalition. And we look at methane with Drew Shindell, professor of Climate science at Duke University and Author of the UN Environment Programme’s Global Methane Assessment, who tells us a reduction in methane could give us a quick fix in terms of efforts to stabilise global temperatures.

A new study published in the British Medical Journal suggests monkey pox might be passed from person to person before symptoms show. Esther Freeman, Assistant Professor of Dermatology at Harvard Medical School and Director of Global Health Dermatology at Massachusetts General Hospital, has been following the current wave of transmission and gives us her analysis of this latest finding, The COP 27 climate summit kicks off next week. To discuss some of the issues we are joined by Simon Lewis, Professor of global change science at University College London and Swenja Surminski, Professor in Practice at the Grantham Research Institute and a member of the UK's Committee on Climate Change. Mark Miodownik, the UCL Professor of Materials & Society, tell us the results of his citizen science project looking at composting plastics. And from the short list for the Royal Society Insight Investment Science Book Prize, we hear from Professor Rose Anne Kenny on her book Age Proof: The New Science of Living a Longer and Healthier Life.

New recordings featuring the voices of 53 species of turtle, caecilian and tuatara previously thought to be silent have illuminated the evolutionary origins of vocal communication. Gabriel Jorgevich-Cohen a PhD student at the University of Zurich has travelled the world collecting recordings and summarised his findings in Nature Communications this week. He spoke to BBC science correspondent Georgina Rannard who explains his findings, what they mean, and shows us some of her favourite turtle sounds. What was it like to advise the government during the height of the pandemic? How soon did experts realise the colossal impact Covid would have? Were mistakes made? The latest in our series of interviews with those shortlisted for the Royal Society Insight Investment Book prize, Vic sat down with co-authors Sir Jeremy Farrar and Anjana Ahuja to talk about their book Spike: the Virus vs the People. Anne-Claire Fabre Assistant Professor at the University of Bern and Curator of mammals, Natural History Museum Bern turns her scientific curiosity toward a surprising and perhaps perturbing behaviour in one of her research animals as she spoke to us about her paper published in the Journal of Zoology this week. Whilst investigating the Aye Aye, a nocturnal primate with two long thin fingers Anne-Claire witnessed the creature putting them to good use picking its nose and went on to uncover a big gap in our understanding of this icky behaviour.

Recorded in front of an audience at Bradford’s National Museum of Science and Media, we’re delving into the next 100 years of broadcasting, examining the science and technology behind what we’ll watch and listen to. And what the seismic technological shifts mean for all of us. Victoria Gill is joined on stage by four people who give us an audio tour of that media future. Lewis Pollard the curator television and broadcast at the museum. Dr Karen Thornton programme leader teaching film and television production at the University of Bradford. Bill Thompson technology commentator. Gemma Milne writer and researcher interested in how science and technology impacts all of us. And author of Smoke and Mirrors - how hype obscures the future and how to see past it. BBC Inside Science is produced in partnership with the Open University

Avian or bird flu is normally seasonal, disappearing as migratory birds leave for winter. However a new strain which seems to spread more easily between wild birds and into poultry has led to the deaths of far more birds than usual. David Steel, Nature Reserve Manager on the Isle of May relates his observations of the effects on seabirds. And Nicola Lewis, Director of the Worldwide Influenza Centre at the Francis Crick Institute tells us why this particular stain is so severe. Climategate was a strange kind of scandal, based entirely on misinformation pushed by climate change deniers. In his new book Hot air, shortlisted for the Royal Society Insight Investment science book prize, Climate scientist Peter Stott assess the impact of their campaign. Pong was a very basic video game developed in the 1970s, now Australian researchers have trained human brain cells in a dish to play the game, Dr Brett Kagan from Cortical Labs explains why.

The virus which causes Covid 19 is continuing to evolve, but into several different closely related strains rather than more new variants such as Delta and Omicron. Ravi Gupta, Professor of Clinical Microbiology at Cambridge university gives us his assessment of the current picture, and Jeremy Farrar, Director of the Welcome Trust, comments on global efforts to counter the virus. The Nobel prizes were awarded this week. Science Journalist Philip Ball looks at the winning discoveries and the scientists behind them. And shortlisted for the Royal Society Insight Investment Science book prize, we hear from Henry Gee, author of A Very Short History of Life on Earth.

The government has lifted a moratorium on fracking imposed in 2019 following a series of small earthquakes caused by exploratory drilling. The British Geological Survey was asked to investigate, we speak to two of the authors of their new report into fracking and earthquakes, seismologist Brian Baptie and Geologist Ed Hough. We also look at more practical aspects of fracking in the UK with Professor Richard Davies from Newcastle University, asking how to viably extract shale gas in the UK and whether, with concerns over climate change, we should really be contemplating this at all. The production of Bitcoin consumes as much energy as a medium sized European country. Benjamin Jones from New Mexico university and Larisa Yarovaya from Southampton Business School explain why generation of the cryptocurrency has come to require such huge amounts of energy. And we hear from Maria Fitzgerald, chair of the panel for the Royal Society book prize on what makes a good science book Inside Science is produced in partnership with the Open University

The sub Arctic boreal forests stretch across the northern hemisphere. They represent a huge carbon sink , but are also vulnerable to climate change. Most of the forest is in Russia and most of what we know about its current state comes from long running international field studies. The Scott Polar Institute in the UK has been studying these forests for years in collaboration with Moscow university, but this year’s field work has been cancelled. We spoke to Olga Tutubalina and Gareth Rees who have been running the collaboration since the 1990s. Will the cost of living crisis lead to an increase in food poisoning ? it’s a concern for food researcher Ellen Evans from Cardiff Metropolitan University, in particular the potential for listeria to grow in our fridges if we don’t have the temperature low enough. And if you like maths how can you get better? Mathematician and Author Simon Singh, tells us about his new global Maths Circles initiative to connect maths enthusiasts around the world.

The James Webb Space Telescope continues to beam exciting data back to earth from exoplanet systems, galaxies and stars further away than we’ve ever seen before. But what happens to that data when it reaches us? We spoke to Julien De Wit from MIT about how exactly we process the vast amounts of information sent back to us from the telescope and how sometimes our computing systems just can't keep up. The British Science Festival is taking place in Leicester this week, and diversity and inclusion is one of the top priorities. Many groups are still alarmingly under-represented in STEM including women, Black and Minority Ethnic people Angela Saini and Dr Kate Clancy explain how we got here and just how alienating science can feel. To explore possible solutions we spoke to the incoming president of the British Science Association and CEO of Stemettes Anne-Marie Imafidon MBE, Early career Engineer and Chairperson of Stemette Futures Youth Board Floriane Fidegnon-Edoh and Physicist Dr Jessica Wade who works in public engagement in STEM and advocacy for women in physics. Finally, are colourful birds more vulnerable? Researcher Dr Rebecca Senior from Durham University takes us through how the pet trade affects bird conservation. Presenter: Victoria Gill Producers: Emily Bird, Julian Siddle and Harrison Lewis

The discovery of a body missing a foot in a thirty one thousand year old grave suggests our ancient ancestors may have been capable of performing complex surgery. The foot seems to have been cleanly amputated, and the patient survived for several years afterwards. Dr Tim Maloney from Australia’s Griffith University made the find and Charlotte Roberts Emeritus Professor of Archaeology at Durham University who researches the evolution of medicine gave us her analysis. Craters from meteorites aren’t always easy to find, they can look similar to other geological features. However techniques more closely associated with forensic science are helping to provide clues. it’s all in the way the incoming asteroid or meteorite burns everything in its path says Dr Ania Losiak from the Institute of Geological Sciences, Polish Academy of Science. The Greenland ice sheets are melting, a new analysis paints a concerning picture about the impact on sea levels. Researcher Jason Box takes us out onto the ice to see this process in action. And why do chimpanzees drum? Language researchers Catherine Hobaiter and Vesta Eleuteri have been following them around the jungles of Uganda to find out.

As parts of England enter drought conditions we ask what are the drivers for drought and what can we do about it? With Dr Jess Neumann, Hydrologist at Reading University, Aidan McGivern meteorologist at the Met Office and Professor Richard Betts, Chair in Climate Impacts at University of Exeter. What influence do Scientific Advisors really have on government? We explore the tricky issue with science writer Philip Ball. Are there just too many satellites now orbiting the earth? Astronomers are increasingly finding their presence is interfering with astronomical observations. Jane Chambers reports from Chile. And what is mucus actually for and how did it evolve? Omer Gokcumen, Associate Professor of Biological Sciences and Stefan Ruhl, Professor of Oral Biology at the University at Buffalo reveal its origins in our aquatic ancestors and its vital role in mouth hygiene. Presented by Alex Lathbridge Produced by Julian Siddle Assistant Producer Emily Bird

Research on recent extreme fire events shows they have a direct effect on the size of the seasonal ozone hole over Antarctica. Climate scientist Jim Haywood is concerned more frequent and extreme fires predicted by climate models could negate all the work done to reduce the ozone depleting chemical pollutants which became such a concern more than 30 years ago. We look at two very different approaches to marine conservation , and discuss how the combination of monitoring and surveillance technology and engaging with local people could help preserve many marine species . And it's festival time in Edinburgh , but we take a look at its more sinister side. How when the city became a centre for the study of anatomy it also developed a dark underbelly of serial killers and body snatchers. A new exhibition clears up some of the myths associated with this period. And the Royal Society has announced its annual medals, a variety of awards for leading scientists. This year there is a special award for Laboratory technicians, the unsung heroes of science experiments. We speak to the winner and also the BBC journalist who as a student destroyed one of his experiments.

Did the Chicxulub meteor that did for the dinosaurs have a smaller companion? Dr Uisdean Nicholson and Professor Sean Gulick talk to Vic Gill about the newly discovered Nadir Crater. Located on the other side of the Atlantic, it’s raising questions about whether Earth was bombarded with not one, but two, meteors on the day the dinosaurs were wiped out. Back in January, the Hunga-Tonga Hunga-Ha’apai volcano in Tonga erupted explosively, triggering a massive tsunami across the Pacific. Now, engineers are remotely scanning the volcano from 16,000km away in Essex. Ashley Skett from SEA-KIT International and Dr Mike Williams from NIWA describe how a robotic vessel is mapping the Tongan seabed. And we get to the bottom of the mystery surrounding a 500-million-year-old fossil…quite literally. The microscopic, fossilised beast, which has no anus, was previously thought to be our earliest known ancestor. Emily Carlisle from the University of Bristol explains how the theory was debunked. Presented by Victoria Gill Reporting by Emily Bird Produced by Alex Mansfield

Professor Anna Hogg joins us on today’s programme for some polar explorations, we speak to one team recalculating arctic warming estimates and another who are storm chasing in Svalbard. Antii Lipponen from the Finnish Meterological Institute talks us through how quickly the arctic is really warming and Professor John Methven and PhD student Hannah Croad from the University of Reading send greetings from Svalbard where they’re chasing arctic storms. Also, new evidence for a possible biomarker of ME/Chronic Fatigue Syndrome - a condition associated with debilitating tiredness and brain fog similar to Long Covid. The microclots, described by Professor Doug Kell at the University of Liverpool and Professor Resia Pretorius of University of Stellenbosch, suggest a possible inflammatory cardiovascular element to the disease which might one day forge a path towards new treatments. And how can trees help us in a heatwave? Vic joined Dominik Spracklen from the University of Leeds on a stroll around a Cumbrian forest to explore the cooling potential of forests. Presented by Victoria Gill Reporter Emily Bird Produced by Alex Mansfield

ESA announce that Shaun The Sheep will fly around the moon this month aboard Artemis-1 mission. Philippe Deloo tells Gaia Vince what's in store for the woolly astronaut this month. Philippe is the team lead on the European Service Module, the part of NASA's Orion spacecraft which will be the workhorse of the new moon missions, ferrying four astronauts at a time to the moon and perhaps even beyond one day. This first Artemis mission, slated for launch 29th August, will check all the engineering bravado of the new launch and orbital systems ready for subsequent human passengers in a couple of years. Christiana Scheib, of the Universities of Cambridge and Tartu, is part of a team who seem to have pinpointed in time the moment the Herpes virus that causes cold sores first spread across human populations. By obtaining genomes of HSV1 from four individuals who died between the iron age and medieval times, their analysis suggests an initial emergence sometime in the Bronze age. The intriguing hypothesis that accompanies the discovery is that the variant's emergence was facilitated by a new trend among bronze age folk of romantic kissing. But as she describes, it's hard to be certain for "there is no gene for kissing". One way of restricting the spread of many viruses is of course various forms of PPE. The last few years have seen billions more items of PPE used on our planet, often without a clear plan for their disposal, and they get accidentally dropped and even deliberately dumped all over the world. Alex Bond of the Natural History Museum at Tring observes and catalogues rubbish affecting wildlife. He took the BBC's Victoria Gill on a walk down a canal in Salford to discuss the issues with the tissues. Presented by Gaia Vince Produced by Alex Mansfield

The severity of last week's heatwave is changing the narrative. Gaia Vince talks to Simon Evans, deputy editor of the climate publication Carbon Brief, who has been following the media coverage of this heatwave, and Lorraine Whitmarsh, professor of environmental psychology at the university of Bath. What has the recent hot weather done to the plants in our gardens, and the crops in our fields? Dr Nicola Cannon from the Royal Agricultural University in Cirencester tells us the low-down. Expect your potatoes to get more expensive this autumn. The RHS want to know about how the heatwave has affected YOUR garden. You can help science by answering on this survey https://www.surveymonkey.co.uk/r/NVNH5FN What if we could use all the excess heat from summer, and store it to heat our homes in winter. It's something a team in the Netherlands and Austria have been looking at, using a thermochemical battery. Wim van Helden from AEE Institute in Gleisdorf in Austria explains how they made a prototype, and what the stumbling blocks are to widespread use of their system. Is this thermal battery the holy grail of heat supply? We run it, and other options, past Michael de Podestra. An ex-measurement scientist at the National Physics Laboratory until his retirement two years ago, he has since become an expert in retrofitting his house to try and make it carbon-neutral.

The Multiverse Laura Mersini-Houghton is an internationally renowned cosmologist and theoretical physicist and one of the world's leading experts on the multiverse and the origins of the universe. She talks to Gaia Vince about finding evidence that supports her multiverse theory as more than just a hypothetical collection of diverse universes, including the one that houses our planet. She also shares her story of growing up with the horrors of a brutal Albanian communist regime. Glacier Collapse In Italy this month eleven people were killed when Marmolada glacier collapsed. A few days later, hikers recorded another huge glacier collapse in Kyrgyzstan. Is there any way of monitoring glaciers to give us a warning of these events? Glaciologist Liam Taylor, a researcher at Leeds University explains to Gaia our options for monitoring vulnerable glaciers, and why a black spot in those observations is about to open up. Pees and queues. Lower urinary tract symptoms are common and affect an estimated 60% of men and 57% of women. These can be detected using a gadget called a uroflowmetre, but patients often face delays getting to clinics to use one. Dr Lee Han Jie and Professor Ng Lay Guat, with colleagues at Singapore General Hospital and the Singapore University of Technology and Design have developed an artificial intelligence algorithm that is trained to listen to patients pass urine. From just the noise of peeing, the AI is able to identify abnormal flows and could be a useful and cost-effective means of monitoring and managing urology patients at home. Heatwave Records Richard Betts from the Met Office explains why the official highest temperature is only 40.3C, whereas many of us have clocked temperature in the mid forties in our cars and on patios.

The James Webb Space Telescope is finally in business - what further treasures will it find? Also, the origins of the International Moratorium on Whaling, 40 years old this month. This week NASA invited President Joe Biden to help them publish the first of five images of full scientific value from the newest super telescope now operating a million miles away from us. It is capable of gazing as far deep into the sky as humans have ever gazed. That first image, an upgrade of one of the Hubble Telescope's "Deep Field" shots from some years ago, shows some of the oldest matter ever seen, including light distorted into smudges and whorls by the gravitational field of galaxies in line of sight from us, much nearer and younger than the light being bent around them. The other images show even more of what the telescope is capable of seeing. Dr. Stefanie Milam of Nasa's Goddard Space Flight Centre in Maryland, US and BBC Science correspondent Jonathan Amos talk to Gaia about this new, exciting phase in astronomy. This month marks 40 years since the International Whaling Commission decided to pursue a moratorium on commercial whaling. Many whales are still struggling, but scientists have seen several species recover since then. The moratorium followed campaigning in the 1970s by such groups as Greenpeace, and even the commercial success of audio recordings of humpback whales, released by Drs. Roger and Katy Payne. Greenpeace co-founder Rex Weyler describes to Gaia the motivations behind the original Save the Whale campaign, and some of his memories of intercepting a Russian whaling ship in 1975. Since 1982, cetacean science has come a long way, and scientists know far more about whale's behaviour, vulnerabilities and interaction with ocean climate and ecosystems than we did back then. Dr. Asha De Vos of the University of Western Australia describes the science, including some recent findings on the continued perils of anthropogenic noise to these giants of the deep.

Gaia Vince takes you for a mosey around his year's Summer Science Exhibition, held by London's Royal Society. Along the way, PRS Sir Adrian Smith talks of reforming A-Levels and a sorry international science collaboration situation as many european research grants are terminated amidst a Brexit withdrawal agreement stand-offs. The Royal Society Summer Science Exhibition is on until Sunday 10th July, it is free to attend and there are many activities and events online too. Presented by Gaia Vince Produced by Alex Mansfield

In 1964 a theoretical physicist called Peter Higgs suggested a mechanism via which elementary particles of a new theoretical scheme could obtain mass. It had been a thorny mathematical stinker in the framework that today we now call the standard model of particle physics. Ten years ago this July, the particle this mechanism predicted, the Higgs Boson, was confirmed to exist in experiments conducted at the Large Hadron Collider at CERN. Prof Frank Close, whose new book - Elusive - is published this week, is a friend of Peter's. The book describes the background to Higg's idea, and how a generation of physicists worked to test it and identify it. He and Prof Malcolm Fairbairn of King's College London discuss the significance at the time, what we we've learned since, and what we might in the future. As covid cases are on the rise again in the UK, Prof Jonathan Ball gives Marnie his observations on the current variants. Prof Trevor Cox, acoustician at Salford University describes his part in a collaboration to design a new type of DIY facemask that still allows people to see your lips moving as you speak, whilst also muffling your words far less. It was developed with collaborators at University of Manchester, and also by Salford's Maker Space, and you can download plans and a video and have a go yourself at the link from our programme page. An article in Nature food recently suggested that our estimates of food miles, the carbon footprints we assign to the foods we eat, may have been underestimated and could be 3.5 times what was previously thought. But does that change the choices we make in what we buy? Presented by Marnie Chesterton Produced by Alex Mansfield

How hard is it to get to Mercury and why are we going? Also, do science festivals work? And why did mammals survive when dinosaurs died? Marnie Chesterton and guests dissect. As this programme went out, scientists and engineers eagerly wait for new images of the planet Mercury to arrive, snapped from a speeding probe passing just 200km from the surface, as it desperately tries to shed some velocity on its seven-year braking journey. ESA/JAXA's BepiColombo mission to Mercury is using gravitational swing-shots (just four more to go) to lose enough energy to eventually, in Dec 2025, enter orbit around the planet closest to our sun. Dr Suzie Imber of Leicester University has skin in the game, being co-investigator on one of the instruments that will eventually be able to teach us more than we've ever known about this bizarre world. Suzie is also last year's winner of the Royal Society's Rosalind Franklyn Award, and works hard doing science outreach talks and events to help inspire the next generation of scientists and engineers. Thurs 23rd June is International Women in Engineering Day, celebrating remarkable engineering as a career option. Report Emily Bird goes along to the Great Exhibition Road Festival to see how science festivals such as this one can help raise the profile of engineering and scientific endeavours in the society of tomorrow. One thing most kids like is Space. The other is dinosaurs. But what about long-dead Mammals? Prof Steve Brusatte of Edinburgh university is a palaeontologist and author whose last book on dinosaurs even led to him being consulted for the latest film in the Jurassic Park franchise. Why then does his new book focus on furrier beings in The Rise and Reign of The Mammals? He tells Marnie of the exciting millions of years of evolution that led to us, after the dinosaurs croaked their last,.

Marnie Chesterton and guests mull over the saga of an AI engineer who believes his chatbot is sentient. Also, climate scientists propose a major leap in earth system modelling, that might cost £250m a year but would bring our predictive power from 100 km to 1km. And the story of a Malaysian Breadfruit species that turns out to be two separate strains - something locals knew all along, but that science had missed. Philp Ball's latest book, The Book of Minds, explores the work still to be done on our conception of what thinking is, and what it might mean in non-human contexts. Beth Singler is a digital ethnographer - an anthropologist who studies societal reaction to technological advancement. They discuss the story this week that a google AI engineer has been suspended on paid leave from his work with an experimental algorithm called LaMDA. He rather startlingly announced his belief that it had attained sentience, publishing some excerpts from interactions he has experienced with it. Prof Dame Julia Slingo this week has published a proposal in Nature Climate Change, co-authored with several of the world's greatest climate scientists, for a multinational investment in the next generation of climate models. Currently, models of the global climate have a resolution of something like 100km, a scale which, they suggest, misses some very fundamental physics of the way rain, clouds and storms can form. Zooming into 1km resolution, and including the smaller physical systems will allow scientist to better predict extreme events, and crucially how water interacts in a real way with rising temperatures in different climes. And can zooming in on taxonomy reveal insights in conservation and biodiversity? Researchers in the US and Malaysia have described a species of breadfruit that has hitherto been considered one species by mainstream science. Locals have long described them as different species, and the genetics proves that view correct. Can more local, granular knowledge help us get a better handle on the conservation status of our planet's biodiversity? Emily Bird Reports.

This week on inside science Marnie Chesterton is looking at how companies measure and account for their use of renewable energy, how politics is impacting science funding in the UK and the technology behind the Queen’s holographic stand in at jubilee celebrations. Dr Anders Bjorn from Concordia university in Montreal talks us through ‘Renewable Energy Certificates’ explaining how they can sometimes be disconnected from real-life reductions in emissions. As he explains in a paper in Nature Climate Change this week, this is a problem, with businesses buying renewable energy certificates that may, even with the best of intentions, mean that corporate estimates of how much they have transferred to renewable energy could be out by as much as two-thirds. For example, in Poland, where much of the grid is powered by fossil fuels, a company can buy RECs from energy producers in Norway, where so much of the grid is de-carbonised and users feel no need to purchase such a certificate. As negotiations on the New Greenhouse Gas Protocol get underway, and delegates in Bonn discuss COP 26 progress, yet more food for thought. In the UK, some long term collaborations and research structures are under threat as the ratification of UK membership of Horizon Europe continues to be delayed. This has led to some researchers running out of funds, some having to relinquish membership, and others moving to different institutions in Member Countries. Professor Nicky Clayton at the university of Cambridge has for many years run a “Corvid Palace” where she keeps very clever birds and examines their thinking. It is threatened with closure, and she is searching for funding to keep the research going, even setting up an open letter from academics around the world in support of this globally renowned facility. Carsten Welsh, a physicist at Liverpool University has also been impacted, facing a difficult decision about whether to give up leadership of his newly funded project or leave the country to pursue it. EU Horizon is one of the most ambitious and well-funded research and international collaboration schemes in science and with every EU nation signed up and countries like Canada and Japan keen to join too, it's no wonder the UK wants to take part. Martin Smith, head of policy lab at the Wellcome Trust explains what’s getting in our way and what might happen next for British scientists who rely on Horizon to fund their research. And finally, celebrations last weekend for the celebration of Her Majesty’s Platinum Jubilee were seemingly led by a holographic queen riding in the Golden State Coach at the head of the pageant in London. At least, that was how it was reported. But was it really? BBC Inside Science managed to track down the leader of the team that made it – whatever it was – happen, and in a generous world exclusive, Willie Williams, head of Treatment Studio, kindly spills the magic beans on quite how you make a Royal Hologram. Presenter: Marnie Chesterton Assistant Producer: Emily Bird Producer: Alex Mansfield

Society itself and the ways we live have been transformed in 70 years of science. Marnie Chesterton, Andrea Sella, and Gemma Milne take a tour of the archive to evaluate some of the biggest hits on Inside Science's jubilee list. What did we miss? Presented by Marnie Chesterton. Assistant Producer Emily Bird Produced by Alex Mansfield

Why are non-African monkeypox cases causing concern? Also, the first complete human genome from a Pompeiian cadaver, and how YouTube is aiding animal behaviourists. As cases of monkeypox appear strangely dispersed around Europe and elsewhere in the world outside of Africa, BBC health and science correspondent James Gallagher outlines to Vic the symptoms and some of the mysterious elements of this outbreak. In Pompeii, scientists have for the first time managed to sequence the whole genome of an individual killed by the eruption of Vesuvius in 79AD. Serena Viva of the University of Salento describes the site of two individual's tragic demise all that time ago, one female aged around 50 years, and a younger male, both leaning on a couch in a dining room. Geneticist Gabriele Scorrano describes how the ancient DNA (aDNA) was preserved and extracted, and how the male individual's genome was so well preserved it could be sequenced in full. As they suggest this week in Nature, there weren’t too many surprises in what they found, but the ability to do this sort of science opens up a new era of Pompeiian archaeological treasure. Faced with covid lockdowns and unable to observe in the wild, elephant conservationists Nachiketha Sharma and Sanjeeta Sharma Pocharel decided to see if videos uploaded to YouTube could enlighten science on rare behaviours of Asian elephants. African Elephants are known to have a strange fascination, even respect, for the death of other elephant individuals, especially those near to their families such as calves and parents. Asian elephants’ thanatological (death related) behaviour is less well observed however. But the researchers turned to videos of strange grieving-like behaviour to begin a catalogue of the different reactions such as carrying dead calves, standing guard, or vocalizing. They dedicate their work, published by the Royal Society, to the elephants involved. This sort of research, using video observations captured and shared by members of the public are proving rather useful to zoologists and animal behaviourists. Ximena Nelson of the University of Canterbury in New Zealand was one of the first scientists to suggest the usefulness of trawling the internet for odd video of animals and explains a bit more to Vic.

Since 2018, Nasa's InSight Mars lander has been sitting on the surface listening to the seismic rumbles of the red planet's deep interior. But this week, plans were announced to finally phase down its activity, as martian dust obscures too much of its solar panels to power it through the forthcoming winter. Jon Amos tells Vic Gill of some of its many successes, and quite why it didn't fly with a duster on board. 50 years of observations across Australia's northern tropical forests suggest yet more bad news for the climate. Trees’ mortality has, it seems, doubled since the 1980s. As Oxford University's David Bauman tells Vic, it seems to be linked to a drying of the air as temperatures rise, and if the trend is also true across the world's other moist tropical forests, they could rapidly slip from being carbon sinks, to carbon sources. Conservationists say we’re losing animal species faster today than at any point in the last 10 million years of Earth’s history. And one approach aims to save as many of those lost animals as possible – after they’ve died. Biobanking – saving frozen tissue from dead animals for future cloning or other reproductive technologies could buy us time to prevent extinction - or even reverse it. Vic visits Nature's Safe, where technology used in pedigree breeding is being deployed to preserve the cells and tissue of endangered species when individuals die or are euthanised, for possible research in the future, or even cloning. Meanwhile, 2.5 miles off the coast of Jersey, archaeologists are holing up in a medieval fortress waiting for the few lowest tides of the year to give them access to the Violet Bank - an area of reef thought once to have been home to Neanderthal populations, but which now is for most of the year submerged by the sea. Marnie Chesterton has been talking to UCL’s Matt Pope between the ebbs and flows. Presented by Victoria Gill Reporters: Marnie Chesterton and Jonathan Amos Produced by Alex Mansfield

Astronomers have captured the first image of Sagittarius A*, the gargantuan black hole at the centre of our galaxy. Dr Ziri Younsi, University College London, shares what it took to capture a picture of a supermassive black hole that is 26,000 light-years away and from which (almost) nothing, not even light, can escape. The world’s largest and most powerful particle accelerator, the Large Hadron Collider, is restarting after three years of upgrades. Roland Pease visits the European Particle Physics Laboratory, CERN, to see how things are going, and looks back on some of the team's past successes. Also, how do you investigate the mysterious deaths of the world’s biggest fish when their bodies sink without trace? That’s the quandary facing marine scientists who’ve been trying to figure out what exactly is killing whale sharks. Freya Womersley, UK Marine Biological Association, shares how satellite tracking technology is helping us solve the mystery. And finally, what’s in a name? As our inventory of Earth’s biodiversity progresses, the number of species given a Latin name is also growing. So, where do scientists find their naming inspiration? In Royal Society Proceedings B this week, an analysis of nearly 3,000 parasitic worm species uncovered some intriguing patterns and worrying biases. Samara Linton reports.

With the cost of living spiralling, many are probably thinking more about the price of food than lithium, titanium, copper or platinum. But the volatility in the global market for these materials - partly because of the pandemic and geopolitical unrest - is causing 'chaos' in the technology supply chain. Elizabeth Ratcliffe, Royal Society of Chemistry, tells Vic that many of us are unwittingly stockpiling these precious metals in our homes, in our old phones and defunct computers, because we don't know what to do with them. Reporter Samara Linton visits N2S, a company in Bury St Edmunds which has found a way to recycle the precious metals and other scarce elements in discarded circuit boards using bacteria. This week more evidence that spring is springing earlier, as Vic heads to what might be the most studied woodland in the world: Wytham Woods in Oxfordshire. Ella Cole, Oxford University, explains how climate change is causing birds to lay eggs three weeks earlier than they did in the 1940s. And Chris Perrins, of Oxford University, shares his thoughts on the changing woodland. And from new life to the very stuff of life. Could the building blocks of DNA have first been delivered to earth on a meteorite? In a paper in Nature Communications, scientists announce the discovery of the last two of the five key nucleobases locked in meteorites dating to the formation of the solar system. Samples of the Murchison Meteorite, a specific type of soft, loamy rock (CM2 carbonaceous chondrite) that fell to earth in 1969, have been re-examined, and the confirmation extends the ongoing debate around the nature and composition of terrestrial life's original crucible. Sara Russell, Professor of Planetary Sciences at London's Natural History Museum, helps Vic unravel the complicated and surprisingly controversial history of space rocks and primordial soup. Presented by Vic Gill Producer: Alex Mansfield Reporter: Samara Linton

This week, we begin with a disturbing medical mystery. Since the start of the year, almost 200 children worldwide have fallen ill with hepatitis—or liver inflammation—without any apparent cause. Most of the children are under five, and nearly half of the cases were in the UK. Vic Gill asks clinical epidemiologist Deepti Gurdasani, Queen Mary University of London, what we do and don't know about these rare cases. Also on the programme, with a huge tidal range, Wales and the west coast of England have become the focal point for a new generation of tidal power plans. So, is the tidal energy revolution finally happening? Roger Falconer, Emeritus Professor of Water and Environmental Engineering at Cardiff University, and Andrew Scott, CEO of Orbital Marine Power, which has demonstrated a working tidal stream turbine - called O2 - off Orkney, share their insights. And fancy eating an insect burger? Or how about adding seaweed smoothies or mycoprotein meatballs to your diet? Fellow BBC science correspondent Helen Briggs shares how lab-grown proteins could make our diets much kinder to the planet. And a recent study has found that a fifth of reptile species are at risk of extinction. Conservation scientist and study co-author Monika Bohm, Indianapolis Zoo in the US, tells us how, despite the gloomy findings, she remains hopeful.

Victoria Gill and guests ask why does scientific communication matters in society and how it might be done better, with Sam Illingworth, Berry Billingsley and Ozmala Ismail. The climate crisis and Covid-19 have shown over the recent years the importance of reliable, relatable, transparent and trusted science communication. But just like science itself, it comes in different forms and takes different approaches. Always keen to keep you up to date, BBC Inside Science takes a moment to discuss good practice and how it might be done better. Dr Oz Ismail is a dementia researcher who also finds time to do stand-up, public engagement and a podcast called Why Aren’t You A Doctor Yet? Sam Illingworth is an Associate Professor at Edinburgh Napier University who investigates science and communication between disciplines. He is also a poet and writer, and has a podcast called The Poetry of Science. And Berry Billingsley is Professor in Science Education at Canterbury Christchurch University. Erstwhile science broadcaster, she looks at ways science education could be enhanced through building what her team call Epistemic Insight - transforming the nature of science education in society's younger members. Presented by Victoria Gill Produced by Alex Mansfield and Samara Linton

Could magic mushrooms be the key to a revolution in treating depression? Professor David Nutt, director of the Imperial Centre for Psychedelic Research, thinks so. He tells Vic Gill about recent research suggesting that psilocybin - the psychedelic compound found in magic mushrooms - triggers rewiring of the brain in people with treatment-resistant depression. Vic Gill speaks with trial participant Steve Shorney who was diagnosed with depression 30 years ago. Nanobodies. That's the name scientists have given to the tiny antibodies found in the blood of camelids like llamas, alpacas and camels. Reporter Samara Linton heads to Berkshire to meet the llamas whose nanobodies were recently found to neutralise the Covid-19 virus. We hear from Professor Gary Stephens, University of Reading, who is responsible for the llamas' safety and well-being, and Professor James Naismith, director of the Rosalind Franklin Institute which is carrying out the pioneering research with engineered nanobodies. And just as the James Webb Space Telescope is poised to peer deep into the universe, we look at a recent image captured by its great predecessor, Hubble, which has thrown down a telescopic gauntlet. Astronomer Dr Emma Chapman, author of the book “First Light” guides us through these incredible pictures of the furthest, faintest, most ancient of stars yet seen. Presented by Victoria Gill Reporter: Samara Linton Producer: Alex Mansfield

Covid-19 infections in the UK are at an all-time high. But most people in England can no longer access free Covid-19 tests, and the REACT-1 study, which has been testing more than 100,000 individuals since the pandemic began, ended last week after its funding stopped. Martin Mckee, Prof of European Health at the London School of Hygiene and Tropical Medicine, shares his insights on what these changes might mean for ambitions to 'live with the virus'. This week, the UN's latest Intergovernmental Panel on Climate Change (IPCC) report has unveiled a to-do list of ways to save the planet from climate catastrophe. How do scientists reach a global consensus on climate change amid war, an energy crisis, and a pandemic? Vic Gill speaks to report co-author Jo House, University of Bristol, and Ukrainian climate scientist Svitlana Krakovska who took part in signing off every line of the report while sheltering from the war in Kyiv. And from our planet's present and future to its ancient past. Scientists working on the Tanis fossil site in North Dakota in the US have dug up a dinosaur's leg, complete with skin and scales. Is this 66-million-year-old fossil, alongside similar nearby victims, the key to unveiling those transformative minutes after the infamous Chicxulub asteroid struck the earth and ended the era of the dinosaurs? BBC science correspondent Jonathan Amos has seen the fossil and speaks with Paul Barrett of London's Natural History Museum about the significance of this un-reviewed new finds. And from earth to Mars. After a year of analysing audio recordings from NASA's Perseverance rover, scientists have found not one but two speeds of sound on Mars. Trevor Cox, Professor of Acoustic Engineering at the University of Salford, guides us through this sonic wonder, and how sound may become a key tool for exploring distant worlds.

Energy is essential: every living thing needs energy to survive, and today’s industrialised societies consume enormous quantities of it. At the moment, the vast majority of this comes from burning fossil fuels that emit carbon. But the government is committed to reaching net zero carbon emissions by 2050. Meanwhile, oil and gas prices are rocketing, exacerbated by the ongoing war in Ukraine. And the energy price cap is being raised on April 1st, hitting millions of householders in the UK. While we await the government’s energy strategy, Inside Science looks at how to solve the problem, finding the best possible ways to meet our energy needs while slashing our carbon emissions. Joining us to discuss this are Alice Bell, co-director of the climate charity Possible, and Jan Rosenow, director at the Regulatory Assistance Project. We also hear from Chris Stark of the Climate Change Commission on how the government might meet its decarbonisation targets, visit a Cornish field that might be a rich source of homegrown lithium for batteries, and talk to Jonathan Atkinson from People Powered Retrofit about how to make our homes greener and warmer.

This month the Royal Society of Chemistry released a shocking report on racial inequality at all stages of academia, from research funding to career progression. Black scientists in particular are unfairly disadvantaged when it comes to funding allocation. This is bad for them, bad for science, and bad for society. So how do we change things? Dr Diego Baptista from the Wellcome Trust, Professor Melanie Welham from the UKRI, and Dr Addy Adelaine, from the non-profit organisation Ladders4Action, join us to discuss the issue. Both of Earth’s poles were hit by heatwaves this week. The Arctic was 30 degrees above average for this time of year, and the Antarctic was an unprecedented 40 degrees above average. We are seeing more extreme temperatures everywhere on earth, but for both poles to experience such heatwaves at the same time is highly unusual. Ed Blockley of the Met Office’s Polar Climate Group explains what’s going on. One of the simplest ways to improve your local environment is to plant a hedge, which not only helps wildlife but can reduce flooding and pollution. But what kind of hedge should you plant? Scientists at the University of Reading and the Royal Horticultural Society are beginning a two year experiment to see which combinations of hedges bring the most benefits. Dr Tijana Blanusa tells us why planting hedges and generally greening our gardens is so important in the current climate. Presented by Gaia Vince Producer Cathy Edwards Assistant Producer Emily Bird

The Russian conflict in Ukraine is already causing hunger there, and as Ukraine and Russia are huge grain exporters, the crisis will be far reaching. Food prices everywhere are expected to rise, and there’s fear that the war could affect food supplies in some of the poorest parts of the world. Tim Lang, Emeritus Professor of Food Policy at City University of London, and Dr Hannah Ritchie, Head of Research at the website Our World in Data, join us to discuss food security. Lead is highly toxic to humans and other animals. One source of lead in the environment is the bullets and shot used to hunt wild game, and new research shows that lead shot has a significant effect on birds of prey such as eagles, buzzards and vultures across the whole of Europe. One of the study’s authors, Professor Debbie Pain, explains the research. Many of us have spent the past two years anxiously following Covid graphs, but from next month the government is cutting funding to several surveillance programmes. Mass free testing will also end, though the Office for National Statistics survey will continue. Given that case numbers are rising, is reduced monitoring wise? Professor Adam Kucharski from the London School of Hygiene and Tropical Medicine discusses how important surveillance has been in the pandemic. The last crewed mission to the Moon was half a century ago, and no one has made that one small step since. But a new NASA programme aims to change that, and tonight is the rollout of Artemis I, the first stage on a journey to return humans to the moon, including the first woman on the moon and the first person of colour on the moon. BBC science correspondent Jon Amos paints a picture of what we’ll see tonight.

The High Seas make up most of our oceans but belong to no-one and are largely unregulated, leaving them at risk of plunder. UN talks start afresh this week with the aim of protecting the marine biodiversity of these vast swathes of living ocean. Covid-19 can shrink our brains and lead to cognitive decline, even in mild cases, according to a new study out this week. Professor Gwenaëlle Douaud, who led the research, explains how they used hundreds of brain scans to discover the effects of Covid infection. A completely different discovery this week was made at the bottom of the sea; we hear how, after 107 years, scientists have finally found The Endurance, the lost shipwreck of Antarctic explorer Sir Ernest Shackleton. How might the Russian invasion of Ukraine affect international space exploration? After a Twitter spat between a former NASA astronaut and the Russian space chief, we’re joined by BBC science correspondent Jonathan Amos and BBC Russian’s Nikolay Voronin to discuss how science in Russia and the rest of the world may be impacted by the current conflict. And finally, the stunning discovery of a 330 million-year-old vampyropod fossil, the earliest known relative of modern-day octopuses and vampire squids, gives us an opportunity to imagine the world it inhabited, a third of a billion years ago.

As conflict continues in Ukraine, there are invisible ‘cyber frontlines’ running in parallel to the physical fighting. We hear how the country’s tech scene is responding to the Russian invasion, as Mike Sapiton, Tech Editor at Forbes Ukraine gives us a view from the ground, and Professor Madeline Carr explains why cyber warfare can be particularly dangerous. A major report published this week speaks to a different kind of crisis: climate change. There are stark warnings for humanity and the planet, with the Intergovernmental Panel on Climate Change assessing the impacts of global heating on people and places, as well as how we can adapt to a drastically changed world. One of its lead authors, Professor Richard Betts, reflects on the report. Russia is one of the world's biggest producers of coal, gas and oil, so what might their invasion of Ukraine, and the ensuing sanctions, mean for global energy supplies? Simon Evans, deputy editor of the climate website Carbon Brief, discusses whether we're more likely to see a push towards renewables and energy efficiency, or further reliance on fossil fuels.

In a week of exciting fossils finds we get up close to a 170 million year old pterosaur, found on the Isle of Skye. And over in the States, some fossilised fish hold the clue to what time of year the dinosaurs, along with three quarters of life on Earth, met their end. We hear from researcher Melanie During who tells us how growth patterns in sturgeons' bones reveal the season of this mass extinction. Predictions for how our climate will change over the coming years are essential in setting and meeting emissions targets, however human behaviour is usually left out of climate model equations. Fran Moore and Katherine Lacasse explain why and how they factor public opinion, habits and political trends into their climate model. And finally, why is it so important we clean up after our pets? Dog poo is incredibly nutrient rich, and Professor Pieter de Frenne has been looking into the surprising negative effect any waste left behind can have on woodland and nature reserves. Presented by Marnie Chesterton Producer Cathy Edwards Assistant Producer Emily Bird Made in association with The Open University

With the prime minister proposing an end to self-isolation requirements as early as the end of the month, we thought we would check in with all things pandemic-related this week. We hear from mathematical biologist Dr Kit Yates from the University of Bath and UCL’s Professor Christina Pagel, who, like many scientists, are concerned about the consequences of relaxing protective measures. However, epidemiologist Professor Irene Petersen tells us why she feels it is the right time to loosen restrictions. A new omicron sub-variant has been making headlines this week. Professor David Male takes us through what we know about omicron BA.2 so far. And from possible endings to the pandemic’s origin story. Roland Pease spoke to Beijing-based journalist Jane Qiu who’s gained unprecedented access to the Wuhan scientist at the centre of lab leak theories.

This week the UK-based JET Laboratory broke its 25-year-old record for energy extracted by nuclear fusion - the process that powers the stars. Using temperatures 10 times hotter than the sun, nuclear fusion has the potential to provide vast amounts of energy at a very low carbon cost. But re-creating the power of the stars here on earth is no easy feat, and Roland Pease has been in Culham, speaking to the scientists at the forefront of this breakthrough. We discuss the Advanced Research and Invention Agency ( ARIA. The ARIA bill is about to go through the final stages of parliamentary approval and will have a budget of £800 million to play with over four years. But it’s not without its critics. Many in the science community have questioned ARIA’s transparency and accountability to the public, because the government have decided to exempt ARIA from Freedom of Information Requests. We hear from UKRI head Professor Dame Ottoline Leyser and Professor of Research Policy James Wilsdon. And from blue skies research to blue seas research, scientists have found a surprising seabed community that lives in the cold nutrient-sparse waters under the central arctic ocean: giant sponges. And it turns out these resourceful organisms have been feasting on the thousand-year-old remains of now-extinct worms. We hear from Teresa Maria Morganti from the Max Planck Institute for Marine Microbiology and Autun Perser from the Alfred Wegener Institute, Helmholtz Center for Polar and Marine Research.

Whilst energy prices are shooting up due to gas demand, in the UK the plans for the next generation nuclear reactors are moving ahead. The costs of eventually decommissioning these, and the spent fuel products they will create is all part of the new contract. But what is to be done, and how far have we got with the 70 years of legacy waste piling up in the UK? Claire Corkhill of Sheffield university helps advise the government about nuclear waste disposal. As she tells Marnie, it's a long-term problem that must be dealt with some day, and even future nuclear fusion plants will have radioactive parts when they need replacing. You may feel that spring seems to come earlier each year. Ulf Buntgen and colleagues at the University of Cambridge have been using data from "Nature's Catalogue", a database of observations going back as far as the c18 to determine the dates each year that certain species of UK native plants first flower. And they have found a clear signal that plants are indeed flowering earlier due to climate change, some as much as a month earlier, on average, since the pre-1986 average. Aaron Rice of Cornell University speaks fish. But not fluently. His field of marine bioacoustics is growing fast. The oceans are, it seems, babbling with fish and other animal chatter. But does everything down there make a noise? In a paper published recently his team have traced evolutionary patterns in the ray-finned fish (which means nearly all the things most people would think of as a fish) and found that the ability to produce fishy sounds, be it bone vibrations, swim bladder vibrations or various other techniques, has likely emerged 33 times in this clade alone. Such convergent evolutionary history clearly suggests a strong selective pressure to do so. Aaron describes how much work there is to be done listening to fish, and how it can be used to help find out how life works, and how it may help us preserve it.

Prof Onur Boyman, Director of department of Immunology at University Hospital, Zurich, this week published a paper in the journal Nature Communications that presents a way of quantifying the risk of a Covid patient going on to develop Long Covid (or PACS as some call it) based on certain symptoms, but crucially also two key biomarkers in the blood. As he explains to Gaia, combining the levels in the blood of two key immunoglobulins (IgM and IgG3) with other pointers, first identified last year, allowed him and his team to make successful predictions as to the relative likelihood his sample group of patients might go on to still be exhibiting symptoms beyond four weeks after infection. Asthma is of particular interest to these researchers, partly because it can share this blood signal of Ig markers. Might it even also shed any light on things such as Chronic Fatigue Syndrome? Dr Claire Steves, of Kings College London, whose previous work on symptom gathering Onur's team have built upon, agrees this is a promising bit of work, and also discusses some other potential clues to the Long Covid mystery. But Covid of course is not the the only major cause of death in the world today. A major paper in the Lancet recently is one of the first deep estimates of the global health burden of Antibiotic Microbial Resistance. And it suggests that 1.25 million people died in the world in 2019 because many bacteria are evolving a resistance to our favourite antibiotics. As Prof Chris Murray, Director of the Institute for Health Metrics and Evaluation at the University of Washington who led the massive collaboration explains. The surprisingly huge number points to a massive and growing problem that political and health leaders around the world must address. And finally, the genetics of fingerprints might be a bit better understood thanks to work published in Cell recently. Dr Denis Headon of the Roslyn Institute at the University of Edinburgh talks to Gaia about a huge survey he and colleagues have done looking at the hints certain genes can give as to the types of fingerprints you grow. The genes that seem to govern the general form of your prints are the ones that shape your limb development, rather than skin patterns as perhaps might be expected. And a pro-tip if you want to search the literature for more info on this: use the word "dermatoglyph" rather than the overused and progressively meaningless word "fingerprint".

Why was the blast from the Hunga-Tonga-Hunga-Ha'apai volcano so explosive? Where are we on the global climatic thermostat? And how you can get involved in the Big Repair Project. Gaia Vince speaks with Auckland University volcanologist Prof Shane Cronin, one of the few human beings to have visited the now-disappeared volcanic land bridge that stretched until last week between the islands of Hunga-Tonga and Hunga-Ha'apai. It was destroyed in the disastrous eruption of the volcano beneath it last week that has wrought such devastation to the nation of Tonga, and whose effects were felt in the Americas and detectable all around the world. Why was this submarine eruption quite so explosive, given that the eruption itself was not one of the biggest or longest in living memory? Previous eruptions - notably Mount Pinatubo in the Philippines in 1991 - released huge amounts of particles and sulphates into the stratosphere such that they had a cooling effect on the atmosphere globally, lasting 2-3 years. Prof Richard Betts, Head of Climate Impacts at the UKs Met Office tells Gaia how current estimates of the recent eruption's emissions suggest it will not have such an affect, their being around ten times less than the 1991 event. Richard was one of the contributors to the UK Government’s Climate Risk Assessment 2022 which was published this week. He describes to Gaia some of the modelling that went into it, and the urgency of cutting CO2 and similar emissions it describes. Last year Prof Mark Miodownik, head of the Institute of Making at UCL made a series for Radio 4 called Dare to Repair, looking at the vanishing art and practice of repairing our old and malfunctioning consumer devices, rather than binning them and buying new ones as most of us do these days. At the end of 2021 Mark, together with representatives from manufacturers, consumers, and other groups, took part in a round-table meeting to discuss possible challenges and measures to increase the so-called Right to Repair, towards building a circular economy in the UK for recycling plastic and metals. In this week's show he launches a new citizen science project aimed at gathering granular data on UK citizens views and practices when it comes to "disposable" electronic devices. To take part in The Big Repair Project, to record successes and failures, even to share how impossible it can be sometimes to change a battery, follow the link on the BBC Inside Science homepage.

After 20 years of planning, preparation and a nail-biting build up fraught by delays The James Webb Space telescope finally launched on Christmas day 2021. Anxious astronomers across the globe looked on as the JWST then completed even riskier manoeuvres to unfurl the 18 hexagonal components that make up its 6.5 meter diameter primary mirror. Cosmologist Dr Sheona Urquhart from the Open University tells us about the astronomical community’s tense Christmas day. Fresh from a TV spot on BBC Two’s Digging for Britain this week, Dr Dean Lomax and PhD candidate Emily Swaby share their excitement unearthing Rutland’s ‘Sea Dragon’ and explore what this find could tell us about Ichthyosaurs. At over 10 meters long this ancient ocean predator is the largest complete fossil of its kind to be discovered in the UK. Ichthyosaurs are commonly associated with Dorset and Yorkshire coastlines where fossils are often revealed as surrounding rock is eroded by the elements. Finding an ichthyosaur fossil inland is unusual but not unexpected as the higher sea levels 200 million years ago would put the east midlands underwater. And whilst the palaeontologists have been struggling through the Jurassic mud, cognition researchers at the University of Cambridge have been wowing their birds with magic tricks. Professor Nicky Clayton FRS, Professor of Comparative Cognition, explains what we can learn about the way jays think by assessing their reaction to different sleight-of-hand tricks. Corvids, the family to which these feathered friends belong, have long interested researchers due to their impressive cognitive abilities and Nicky’s team has shown that their Jays are not fooled by all of the same mis-directions as we are, but are fooled by some. And it could be down to not being able to tell the difference between a finger and a feather.

UCL oceanographer Helen Czerski explores life in the ocean depths with a panel of deep sea biologists. They take us to deep ocean coral gardens on sea mounts, to extraordinary hydrothermal vent ecosystems teeming with weird lifeforms fed by chemosynthetic microbes, to the remarkable biodiversity in the muds of the vast abyssal plains. Helen's guests are Adrian Glover of the Natural History Museum in London, Kerry Howell of Plymouth University and Alex Rogers, scientific director of REV Ocean. They discuss the dramatic revelations made by deep ocean explorers in just the last forty years, and the profound connections that the deep sea floor has with life at the Earth's surface. They also consider the threats to the ecosystems down there from seabed mining and climate change. Producer: Andrew Luck-Baker BBC Inside Science is made in association with the Open University.

Dr Kevin Fong convenes a panel of astronautical minds to discuss the next decade or two of space exploration. 2021 was an eventful year in space. Captain James Kirk a.k.a William Shatner popped into space for real for a couple of minutes, transported by space company Blue Origin's tourist rocket New Shepard. Elon Musk's Space X ferried more astronauts and supplies between Earth and the International Space Station, using its revolutionary resuable launchers and Dragon spacecraft. On Mars, the latest NASA robot rover landed and released an autonomous helicopter - the first aircraft to fly on another planet. 2022 promises even more. Most significantly NASA plans to launch the first mission of its Artemis programme. This will be an uncrewed flight of its new deep space vehicle Orion to the Moon, propelled off the Earth by its new giant rocket, the Space Launch System. Artemis is the American space agency's project to return astronauts to the lunar surface and later establish moon bases. China has a similar ambition. Are we at the beginning of a new space age and if so, how have we got here? When will we see boots on the Moon again? Could we even see the first people on Mars by the end of this decade? Even in cautious NASA, some are optimistic about this. Kevin's three guests are: Dr Mike Barratt, one of NASA's most senior astronauts and a medical doctor, based at the Johnson Space Center in Houston, Texas Dr Anita Sengupta, Research Associate Professor in Astronautical Engineering at the University of Southern California Oliver Morton, Briefings editor at The Economist and the author of 'Mapping Mars' and 'The Moon' Producer: Andrew Luck-Baker BBC Inside Science is made in association with the Open University

Victoria Gill hears of ancient DNA evidence for an unrecognised mass migration from continental Europe 3,000 years ago that may even have brought the Celtic languages with it. In a paper in the journal Nature, an international team of researchers have gathered hundreds of middle-late Bronze Age DNA samples to identify a moment in pre-history when half the ancestry of people living in southern Britain became continental European. Sometime around 1000 BC, continental Europeans living in Kent spread rapidly into what is now England and Wales. As Prof Ian Armit tells Vic, the spread need not have been one event, and likely spanned around 200 years, but by the start of the Iron Age, Britons' DNA was 50% changed. The researchers suggest further that this may have been the time when Celtic languages spread from the continent into the islands too. Data are starting to be published that suggest the Omicron variant of SARS CoV-2 may be a little less awful than was first feared, though it clearly is still a lethal foe. Prof Penny Moore, one of the scientists in South Africa who helped alert the world to the new virus is very tentatively relieved that death and hospitalisation numbers there and in the UK are beginning to show clinically some of the resilience that earlier strains and vaccines may have bestowed on populations. Three "Glimpses of Spike", either through prior infection and survival or vaccination and boosting seem to be accompanied by improved survival rates. Gaia Vince has been to the Arctic Circle to talk climate change and reindeer. Sami language and culture in Lapland is under strain as climate change rapidly changes alters the predatory threats reindeer farmers face, increasing numbers of wolves and even sea-eagles that prey on young reindeer calves. And over at UCSC in California, recordings of elephant seal pups have been played to maternal harems to ascertain how well mothers recognize their own. Caroline Casey and colleagues report in Royal Society journal Biology Letters, how they can spot their own offspring from their call alone in as little as two days after birth. But if they can do that, why then do so many lactating females feed pups that aren’t their own? Elephant seal mothers fast throughout lactation and lose a huge percentage of their own body weight, quite what the evolutionary driver is for this behaviour remains uncertain, but it can’t now be a case of mistaken identity.

The launch of the James Webb Space Telescope is only days away. Scheduled for lift off on 24 December, the largest and most complex space observatory ever built will be sent to an orbit beyond the moon. James Webb is so huge that it has had to be folded up to fit in the rocket. There will be a tense two weeks over Christmas and the New Year as the space giant unfurls and unfolds. Its design and construction has taken about 30 years under the leadership of NASA’s Goddard Space Flight Center. With its huge 6.5 metre-wide primary mirror, the giant observatory promises to extend our view across the cosmos to the first stars to shine in the early universe. That’s a vista of Cosmic Dawn: the first small clusters of stars to form and ignite out of what had been a universe of just dark clouds of primordial gas. If the James Webb succeeds in capturing the birth of starlight, we will be looking at celestial objects more than 13.5 billion light years away. Closer to home, the telescope will also revolutionise our understanding of planets orbiting stars beyond the solar system. BBC science correspondent Jonathan Amos reports from the European Space Agency’s launch site in French Guyana from where James Webb will be sent into space. He talks to astronomers who will be using the telescope and NASA engineers who’ve built the telescope and tested it in the years leading to launch.

T-Cells in vaccinated people may be holding the fort, or at least fighting serious illness, against the latest SARS CoV2 variant. Also, how the briefest of sleeps aids creativity. Prof Penny Moore, of South Africa’s National Centre for Infectious Disease and Witwatersrand University in Johannesburg, joins us again this week to give us an update from the front line of scientists trying to get the data we need to try to predict the seriousness of the omicron variant. These early data, published as pre-prints and not yet peer-reviewed, seem to suggest that for those in the world lucky enough to have "seen a spike" three times (double vaccination plus booster, or double vaccination plus recovered from infection) the chances of serious illness remain similar to earlier variants. One chink of hope continues to be the fascinating response of the "killer" T-Cells. Prof Danny Altmann of Imperial College London attempts to give us a T-Cell 101 course. This other division of the body’s defences, besides the binding antibodies of which we hear so much, may be more resilient to the sorts of mutations the virus has shown so far, and also perhaps have a slower waning in their ability to recognize it at all. What did Salvador Dali and Thomas Edison have in common? A fondness for the occasional creative nap. And this week scientists suggest they weren't wrong. Delphine Oudiette, a sleep researcher at the L’Institut du Cerveau et de la Moelle épinière in Paris, has been experimenting with the idea that just a small nap, where you doze off for a few seconds but don't fall into deep sleep statistically helps you solve creative or mathematical problems. Her results are published in the journal Science Advances. Meanwhile, in shallow seas off Indonesia, attempts to regrow coral reefs previously pounded to rubble by fishing with explosives, really sound like they are recovering. How do scientists know? By swimming about with microphones of course. Dr Tim Lamont, a marine Biologist at the University of Exeter has been listening to thousands of recordings of fish and other marine animal noises and talks Vic through some of the odder ones that so far can't be recognized. He says the sheer number and frequency of the odd sounds point to an ecosystem beginning to thrive. The coral rebuilding strategy there won't work for all the world's dwindling corals, but this new way of monitoring success or failure makes for a great listen.

As virologists around the world race to investigate the latest SARS CoV2 variant of concern, the UN’s World AIDS Day this week reminds us of the other global pandemic raging for some 40 years. Much of the work achieved over the last two years on SARS CoV2 has been achieved because of the investment made into, and the understanding gained from, HIV research over the last two decades. But to what further extent do they overlap in the population? There is a theory that the omicron variant, displaying so very many mutations compared to previous variants, might well have been incubated in a person suffering from a compromised immune system, possibly due to HIV, in whom the covid virus was able to linger longer than in fitter individuals. Prof. Penny Moore, of South Africa’s National Centre for Infectious Disease and Witwatersrand University in Johannesburg, is one of many virologists who transferred from HIV to coronavirus research, and hers, like hundreds of labs around the world, is racing to clone the parts of the omicron virus to enable research into its transmissibility and severity as soon as possible. She describes to Vic what we yet know and what we don’t about it, and also how it is high time to bring the same sense of urgency back to HIV research. Nottingham University’s Prof. Jonathan Ball is another virologist who suddenly transferred experience over to coronaviruses early on. He outlines something of what is really happening when viruses mutate, and how the arms race between host and invader can play out. Our regular Inside Science listener will be interested to know that this week Merlin Sheldrake was awarded the Royal Society’s Science Book Prize, sponsored by Insight Investment, and the hefty cheque that accompanies it, for his book Entangled Life: How Fungi Make Our Worlds, Change Our Minds and Shape Our Futures. Merlin is one of several high profile advisors to something called the Society for the Protection of Underground Networks - SPUN. They have received funding recently to begin an international mission to map the world’s subterranean fungal mycelial networks, including the infamous Wood Wide Web. SPUN Co-Founder Prof. Toby Kiers of VU University in Amsterdam tells Vic about the need to preserve, map and cherish this unseen yet essential part of the global ecosystem. And could rising sea levels paradoxically be used to help fight climate change? Researchers up in St Andrews took Vic for a squelch about the salt marshes reclaimed recently by the sea in an estuary near Grangemouth, where flora and fauna are thriving just a few years since the seas were allowed back in. Finally, you may have thought that wasps eat meat whereas bees eat honey and nectar. But this week we learned that some bees eat meat, preserving it in honeycombs to feed young and augment their own nutrition. Intrepid field entomologist Laura Figueroa of Cornell University describes to Vic her work in the jungle with Vulture Bees, social bees that over evolutionary time seem to have rescinded their vegetarian instincts and now are happy to enjoy a bit of “chicken on the side”. Laura found that they can digest their flesh because of big adjustments to their gut microbes, including acid-loving bacteria also found in other carnivorous animals.

Malaria, a disease that infects hundreds of millions of people and kills hundreds of thousands each year. It is caused after a plasmodium parasite is passed from a blood-feeding mosquito into a human host. Subject to much research over hundreds of years, of both host and parasite, one of the evolutionary mysteries has been why the plasmodium so prospers in the mosquito populations in infected areas. Why haven’t mosquitoes’ immune systems learned to fight back for example? In short, what’s in it for the mozzies? Ann Carr, working with Laurence Zwiebel at Vanderbuilt University, reports in the journal Nature Scientific Reports how they managed to discover a mutual symbiotic relationship between the plasmodium and the mosquito. Using advanced sequencing technology they discovered that the infected insects can live longer, and have enhanced sensing (olfaction) and egg positioning than their uninfected brethren. This, in turn, could help them finds meals better, bestowing higher numbers of infection opportunities for the parasite, and benefitting both. NASA this week successfully launched its DART mission, which will next year attempt to nudge an asteroid in its orbit by smashing a mass into it. Could this method allow future humans, endangered by an impending collision push an asteroid out of the way to save the planet? It is billed as human’s first ever “earth-defence mission”, but as relieved-sounding mission leads Nancy Chabot and Andy Rivkin of Johns Hopkins University told the BBC, it is perhaps finally time to stop talking about these sorts of things and have a go. Less relieved perhaps are astronomers around the world, as the James Webb Space Telescope team announce a further small delay to its launch to sometime after December 22nd. The BBC’s John Amos a few weeks ago stood in the presence of the telescope before it was coupled to the launch vehicle, and spoke with ESA’s Peter Jensen about its cost and complexity. BBC Inside Science is planning a special episode devoted to the instrument to accompany the launch of this successor to the Hubble Space Telescope. Watch, as they say, this space... And finally an insight perhaps into the origin of words and language. Apart from onomatopoeia, where a word can sound like the noise of a noise-making thing, can a word sound like other properties, such as for example its shape? In the late 1920s psychologists found that different people would match certain made-up words with the same abstract shapes. This “Bouba/ Kiki” effect has been studied since, where the word “Bouba” is associated with rounded blobby shapes, and “Kiki” with spikier, angular forms. But there wasn’t so much evidence whether or not the effect worked across different languages or different written alphabets, until now. Aleksandra Ćwiek of Leibniz-Zentrum Allgemeine Sprachwissenschaft in Berlin tells Gaia of her international study (published in Royal Society Phil. Trans. B) looking at the effect in 25 different languages and cultures. The effect is robust across the different writing systems and locations, so the link is not simply about the shape of a letter b or letter k when written in a latinate alphabet, but could allude to something much deeper.

Earlier in the week the current ISS crew had to prepare to evacuate after Russia tested an anti-satellite weapon, spreading thousands of high velocity shards of ex-satellite into a reasonably low-earth orbit and potentially endangering many other earth observation and communication satellites of all nations. How can we clear this and all the other debris? BBC Space Correspondent Jonathan Amos tells Gaia Vince about the Russian test and of efforts to de-orbit some other deceased orbital vehicles. Simon Evans, deputy editor of the website Carbon Brief, was one of many attending the COP26 summit which ended at the weekend. How do all the declarations, promises and the "Glasgow Pact" itself add up in the great carbon ledger we all need to worry about? And the last of BBC Inside Science's Royal Society book prize nominees, Jessica Nordell talks to Gaia about writing her book "The End of Bias: A Beginning: The Science and Practice of Overcoming Unconscious Bias". Her investigation into the science of all of our preconceptions and unacknowledged prejudices surprized even herself.

How propane might prevent air conditioning and refrigeration becoming an even bigger burden as our planet warms. Also, covid antiviral pills, and how we forgot to breathe properly. The Montreal Protocol is famous for reducing CFC emissions to help protect the Ozone Layer. We only started using things like CFCs as refrigerants in our fridges and air-conditioning because they weren't as flammable as many alternatives. They were mainly replaced by HFCs, though these are also on the way out. The reason? Their huge greenhouse warming potential (or GWP). Propane has long been thought to be an alternative because of its comparatively tiny GPW, but the safety standards haven't been in place in much of the world for many of the types of application that would make the big difference. Sophie Geoghegan, Climate Campaigner at the Environmental Investigation Agency, and Asbjørn Vonsild who has been working on some of the new standards, due to become normal in Europe next year tell Gaia what greenhouse savings there are to be made, both in terms of efficiency and the contents of the systems themselves. If public opinion and consumer choice can drive the transition as our cities heat up. This week two new Anti-viral pills that are designed to fight SARS CoV2 infections have made headlines in the UK. Professor Penny Ward is Chair of the Faculty of Pharmaceutical Medicine’s Policy Expert Group, and explains how they work, how they were developed, and when they will be properly available. And in the penultimate of our 2021 Royal Society Insight Investment Science Book Prize shortlisted authors, science journalist James Nestor describes his book, Breath: The new science of a lost art. The book documents James’s journey around the world investigating traditional eastern practices, the latest pulmonology research, and learning from the palaeontology of ancient skulls, and he attempts to cure himself with better breathing habits.

Gaia Vince hears how blue whales' huge appetites and energetic eating behaviours helped generate more food for themselves. Also, an update from COP26, and Emily Levesque on The Last Stargazers. New research published this week in the journal Nature reveals new insights into blue whales eating habits. Matthew Savoca and colleagues suggest these biggest of marine animals actually eat up to three times the mass of krill previously estimated. And they do this by finding the blooms of krill and using a spectacular lunging approach to open their massive mouths and filter the gulp of seawater for tonnes of food. But how come, since the near destruction of their population by commercial whaling in the twentieth century, are current krill populations lower than when the voracious whales themselves were far more numerous? Shouldn't there be more krill now than then? The answer, as Victor Smetacek, of the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research in Bremerhaven, describes to Gaia is that whales themselves help to keep iron in the upper waters of the southern oceans, re-fertilizing it for the lower ecosystem member like phytoplankton, and their powerful diving lunges and defecation effectively plough the waters, akin to herds of bison treading manure into prehistoric grass plains. Former GSO David King, of the Centre For Climate Repair at Cambridge University, is beginning experiments next year that seek to mimic this whale-defecation effect to bring about eventual repopulation of whales and fish to allow the oceans to restart this historical cycle. From Glasgow, above the hubbub of delegates and dignitaries CarbonBrief's deputy editor Simon Evans talks to Gaia about his perceptions of progress so far at the COP26 climate summit. Amongst the flurry of declarations so far this week, what are the details and how do they add up towards our eventual recovery back down to the 1.5C rise everybody is talking about? And in the latest of Inside Science's interviews with shortlisted finalists of this year's Royal Society Insight Investment Science Book Prize, Prof Emily Levesque, an astronomer at Washington State University tells Marnie Chesterton of her adventures and astronomical anecdotes at some of the world's most famous observatories. Researching her book, "The Last Stargazers: The Enduring Story of Astronomy’s Vanishing Explorers", she interviewed hundreds of practicing and practical astronomers, many of whose jobs, she suggests, will soon be transformed as the act of observation becomes more remote, automated, and data-heavy.

This week London's Ultra Low Emission Zone was extended to 18 times its previous size. In an effort to cut levels of various nitrogen oxides and other gases dangerous to humans from urban air, cities encouraging lower emission vehicles is a trend soon stretching across the UK and other European countries. But some are sceptical as to their efficacy. Dr Gary Fuller of Imperial College London is author of The Invisible Killer, and has been studying the air in London and elsewhere since these zones began. As COP26 begins in Glasgow, a wealth of climate science is being published and publicised. Victoria Gill describes a couple of stories this week that point out quite how complex the science is, let alone the diplomacy and economics. Whilst the world's forests taken as a whole undoubtedly still capture more CO2 than they release, research this week shows that ten of Unesco's World Heritage Forests - making up for an area twice the size of Germany - have in the last ten years actually moved from being a carbon sink to a carbon source. There are several reasons, land use pressure being one of them, but also extreme climate events like wildfires (and even a hurricane in one instance) have tipped the balance, and show what how sharp the knife edge is for natural resilience. Meanwhile, the Financial Times reports that scientists have found an unexpected outflow of methane into the atmosphere from a site very close to the COP26 conference centre in Glasgow, highlighting just how great a challenge net zero will be. Alongside some of humans' most earth-changing achievements, the domestication of the horse stands as something outstanding in human history. Without it, war, traded and culture would be unrecognizable. But quite when and where the modern horse originated has been something of a mystery. In Nature this week, researchers have published an extensive study into ancient DNA that seems to pinpoint finally a moment and a place where this happened, 4,200 years ago. Geoff Marsh takes Marnie for a canter through the mystery. Presenter: Marnie Chesterton Producer: Alex Mansfield Made in association with The Open University

As many as 43,000 PCR tests for people living in and around the South West of England could have been wrongly returned as negative recently, thanks to a seemingly unknown error, or errors, at a laboratory near Wolverhampton. For an extraordinarily long time the mistakes went undetected, and every day many hundreds of people who really had Covid, were told they hadn't. To discuss the numbers and difficulty in calculating the full tragic consequences of the events, Marnie Chesterton speaks to Dr Deepti Gordasani of Queen Mary, University of London, and Dr Kit Yates, of Bath University. How many people may have died as a result of this? BBC Inside Science's back-of-the-envelope suggests 500-1000 preventable deaths, and counting.. As accusations of fossil fuel lobbying begin to encircle the pre-negotiations of the COP26 negotiations, we heard last week of the sad death of Dutch climate scientist Geert Jan van Oldenborgh. Listeners to BBC Science programmes will recognise his work from earlier this year, as flash floods and heatwaves ravished Europe and North America, when he and his colleagues at the World Weather Attribution Initiative were able to say unambiguously that these events could only have happened because of anthropogenic climate change. Roland Pease looks at Geert Jan's work and legacy. And the latest of the Royal Society Book Prize finalists to speak to BBC Inside Science is Stuart Ritchie, a psychologist at Kings College London. His book explores the murkier corners of science as a process. Certainly the so-called replication crisis has dogged psychological sciences for several years, but in "Science Fictions: How Fraud, Bias, Negligence, and Hype Undermine the Search for Truth" Stuart outlines quite how deep some of the flaws in the modern experimental reporting and publishing model go, and in almost all fields. However, as he explains to Marnie, there may be ways of rescuing the great achievement of the scientific method by tweaking some of our peer-review norms.

Marnie Chesterton hears of a simple test for the earliest signs of Alzheimer's disease. She finds out about UK scientists using robots to map radiation at Chernobyl, and talks to Merlin Sheldrake about fungi. Roland Pease travels to Bath University to meet scientists who may have developed a way to diagnose Alzheimer's in the earliest stages of the disease. Dr George Stothart, has led the team in the development of this simple 2 minute test. Prof Thomas Scott of Bristol University and team develop robotic techniques to scan areas of high radiation that would otherwise be unsafe for humans to enter. Their rolling, quadruped or even flying robots have recently been deployed in and around the reactor building at the Chernobyl disaster site. Authorities there have recently been licensed to begin disassembling remains inside the vast concrete shield, but as they do so, areas of intense radiation are likely to shift from day to day. Being able to map these changes in 3D at the end of each working shift should enable workers to avoid the areas of biggest danger. Dr Merlin Sheldrake is one of the nominees for this years Royal Society Insight Investment Book Prize. "Entangled Life - How Fungi Make Our Worlds, Change Our Minds, & Shape Our Futures" is a rich tale of interconnectedness and subtle intrusion and extrusion between different living things, and particularly fungi's huge influence on human existence, from beer, bread and psychedelia to the whole history of life on earth.

This week saw the announcement of the Nobel prizes for physiology or medicine, chemistry and physics. None of them reward research connected with Covid. Roland Pease, science journalist and Nobel watcher, and Gaia Vince discuss the decisions, which some have said are controversial in this pandemic year. The BepiColombo space craft, a joint European and Japanese mission, has just completed its first fly-by of Mercury, after a three year journey. Professor Dave Rothery, a planetary geologist at the Open University, who’s been involved since the early days of the mission in the 1990s, talks about what Mercury's cameras have seen and what the mission aims to find out when it finally gets into orbit around the planet in 2026. Plants remove carbon from the air during photosynthesis, and forests will be a key part of meeting our climate goals. But there’s a lot of uncertainty about how forests will react as temperatures and CO2 rise. Now researchers at University of Birmingham have bathed ancient oak trees in the sort of carbon dioxide concentrations we expect in 2050, and measured the impact. Anna Gardner led the research from a forest in Staffordshire. The shortlist for the Royal Society Insight Investment Science Book Prize for 2021 was announced last week. Inside Science will be featuring the six authors. The first is The Sleeping Beauties: And Other Stories of Mystery Illness by Suzanne O’Sullivan. She's a consultant neurologist at the National Hospital for Neurology and Neurosurgery in London, who’s been described as “a detective of the mind”. Suzanne O’Sullivan specialises in epilepsy but this leads her to see a number of patients with symptoms such as unexplained paralysis or blindness. For The Sleeping Beauties, she travelled around the world investigating what is often referred to as psychosomatic illness. Sometimes whole groups of people have been affected in mysterious ways. Claudia Hammond spoke to her about the strange case of refugee children in Sweden who fell asleep for years at a time.

Booster vaccines are now being offered to people in England most at risk of Covid, who had their second jab at least 6 months ago. Most people are getting an mRNA vaccine as a booster, mainly the Pfizer one. Dr Andrew Ustianowski, national clinical lead for the UK COVID Vaccine Research Programme, and infectious diseases consultant in Manchester, explains why people are not being offered new vaccines, specifically tweaked to prevent the current highly transmissible delta variant. And he talks about a trial with a new vaccine that works against more than just the spike protein. Why don’t we have a tail? We share that absence with our primate cousins, the great apes. What made the difference genetically speaking has eluded scientists, until now. Professor Jef Boeke of NYU Langone Health tells Gaia Vince why it was a change in just one gene that caused us to lose our tail. New research just published in PNAS pushes back the origins of farming by thousands of years. Professor Kristina Douglass of Penn State University and team studied 18 000 year old eggshells of cassowaries, found in human shelters in New Guinea. She explains how the finds suggest that these Pleistocene people had domesticated these large flight less birds. And six authors this week learned that their books have made the shortlist of the Royal Society Insight Investment Science Book Prize for 2021. Chair of the judges, Luke O’Neill, Professor of Biochemistry at Trinity College Dublin, tells Gaia how the panel made their choices from the 350 books entered.

Thousands of people have been forced to flee the path of the lava that has been spewing from the Cumbre Vieja volcano on La Palma since Sunday 18th September. Dr Rebecca Williams of Hull University is an expert on the geology of the Canary Islands and tells Gaia Vince that eruptions are regular events on the islands. There's been much discussion about where we are going to get our energy from in the UK. Gas prices are soaring, a fire has knocked out a key power cable, and the weather has affected the amount of power that can be generated from our wind turbines. And to meet our climate targets we're going to become ever more dependent on renewable, and variable, sources. Tom Butcher from the Met Office talks about wind forecasting. He says that the winds have been between 10% and 20% lower in intensity this summer. Professor Deborah Greaves, of Plymouth University and Head of the Supergen Offshore Renewable Energy Hub, explains how the UK is planning to increase the number of wind turbines, moving into deeper waters. A team from the Institut Pasteur in Paris, investigating bats in caves in Northern Laos, has found bats that are infected with a coronavirus that’s genetically almost identical to the one now causing Covid in humans. Lead researcher Dr Marc Eloit discusses what they have discovered and how coronaviruses could move from bats to humans. Lewis Hamilton and Max Verstappen had what looked like a very serious crash at their recent Formula 1 race in Italy. Max Verstappen’s car landed on top of Lewis Hamilton’s, but amazingly Hamilton got out unscathed. The safety features on these cars which can travel at more than 200 mph, are very sophisticated. Nick Wirth, a Fellow of the Royal Academy of Engineering who has many years experience of engineering in the F1 world, describes the Halo which saved Lewis Hamilton's life.

NASA's Perseverance rover has been trundling around the Jezero crater since it landed successfully in February 2021. A few weeks ago it made its first attempt at collecting a sample of rock. Unfortunately the rock turned out to be so crumbly it disintegrated away. But Perseverance lives up to its name and has been drilling elsewhere and has now collected two samples. The rover has stored them in special canisters for later collection. Katie Stack-Morgan, Deputy Project Scientist of the Mars 2020 mission at NASA, tells Gaia Vince what they've found out so far. The Inspiration 4 mission has just blasted off from the Kennedy Space Center with 4 civilian astronauts on board. Unlike previous billionaire space flights, which have shot up far enough to officially cross into space before immediately returning, these four are going further out than the International Space Station, where they will orbit the earth for three days. BBC Science Correspondent Jonathan Amos talks about the recent boom in space tourism, and about the Chinese rover on Mars. The terrible Australian wildfires of the summer of 2019/20 had a devastating impact, burning across more than 18 million hectares and causing loss of life and livelihoods.. Now, it turns out the impacts stretched far beyond Australia. Climate scientists have been looking at satellite images of the vast Southern Ocean, which plays a major role in controlling the global climate, and found massive algal blooms, fertilised by debris blown thousands of kilometres from the fires. Gaia discusses the observations with Nicolas Cassar of Duke University, one of the authors on a recent Nature paper, and what they tell us about geoengineering to cool down the earth. This month India licensed the world’s first DNA vaccine against Covid. Jonathan Ball, Professor of Virology at the University of Nottingham, is involved with a DNA vaccine that is just starting in clinical trials. He explains the pros and cons of this kind of vaccine. It could be of benefit to those who are needle phobic.

We’re just weeks away from the big international climate talks in Glasgow, where governments will be trying to figure out a workable plan for how to keep global temperature rise below 1.5 degrees. Gaia Vince explores a couple of strategies to tackle climate change. By far the biggest source of the rise comes from the release of greenhouse gases when we burn fossil fuels, like coal, oil and gas. So it’s no surprise that we need to cut back on this habit - but much of the discussions are over how much of our reserves countries can continue to burn. Earlier this year, a landmark report from the International Energy Agency said there must be an immediate end to new fossil fuel exploration, and that current production must drop by 75% by 2050 if we are to stay within emissions targets. Daniel Welsby from UCL talks to Gaia about his just published massive analysis of fuel reserves and extraction. His study doesn’t go as far as the IEA’s, but still says that 60% of the remaining oil and gas, and 90% of coal reserves must stay underground if we are to keep below that 1.5C temperature rise. Natural gas, or methane, has a much stronger effect on temperature than carbon dioxide, but because it doesn’t last very long in the atmosphere before converting into carbon dioxide, it’s been a bit overlooked by governments. Two recent reports, from the IPCC and the UN, have pointed out that cutting methane emissions would be a quick win in reducing global heating. Most of our methane emissions are because of leaks from the oil and gas industry, or from landfill sites and agriculture. Gaia discusses tackling methane with Drew Shindell, of Duke University in North Carolina, the author of the Global Methane Assessment from the UN Environment Programme. Climate change is already having an impact on life everywhere. We’ve all seen the powerful pictures of polar bears on melting ice, but global warming is also causing problems for species in the tropics. Dani Rabaiotti of the Zoological Society of London explains how climate change is having an impact on African wild dogs, a species which is already endangered. This week the Human Fertilisation and Embryo Authority A recommended that the time limit for using frozen eggs, sperm and embryos, should be extended from 10 years to 55 years. Shahnaz Akbar, a fertility expert at Luton and Dunstable Hospital, explains what has changed in the science of preserving eggs from when the law was originally passed.

Victoria Gill talks to Professor Damian Bailey who's leading research at the University of South Wales into the potential risks to brain health in contact sports players, from impacts to the head and body sustained during play. His latest study found that over the course of a 31 game season, the brains of members of a professional rugby union team underwent measurable changes, particularly the forward players who sustained most tackles, knocks and falls. The findings may help to identify why professional players of some contact sports are at an increased risk of dementia later in life. Also in the programme: How food waste may help with the development of a more sustainable generation of batteries, with Imperial College chemist Magda Titirici. Professor Titirici was awarded this year's Kavli Medal by the Royal Society for her research on new sustainable energy materials. The bones of people who died in 79 AD during the eruption of Vesuvius have revealed in extraordinary detail what the citizens of Herculaneum ate, and how the diets of men differed from those of women in the town. With bioarchaeologist Oliver Craig of the University of York. How the babbling of baby bats is comparable to babbling in human babies. Both are about learning the skills of communication, according to zoologist Ahana Fernandez of the Museum of Natural History in Berlin.

Virologist Marion Koopmans is one of the independent researchers appointed by the World Health Organisation to investigate the origins of the coronavirus pandemic. The team visited China in January this year as a first step to answer how, when and where SARS-Cov-2 first infected humans. Professor Koopmans tells Victoria Gill that time is beginning to run out to launch the next phase of studies, to trace the first people in China to be exposed and identify the animals from which the virus jumped the species barrier. Also in the programme: Is the practise of feeding the birds in our gardens creating losers as well as winners, and causing the numbers of some woodland birds to decline? Conservation biologist Alexander Lees visits Victoria in her garden to discuss the question, and reveal the truly dark side of the Great Tit. A new study of the impact of street lighting on nocturnal insects shows that the local impacts on moths can be dramatic. According to entomologist Douglas Boyes, street lights deter female moths from laying their eggs and make them more vulnerable to predation by bats. He's found that artificially illuminated areas are home to half the number of moth caterpillars compared to dark areas.

A 17,000 year old tusk contains a remarkable story of the lifetime travels of a woolly mammoth which roamed the grasslands of Ice Age Alaska. The animal travelled 70,000 kilometres over the course of three decades before his premature death north of the Arctic Circle. The University of Alaska's Matthew Wooller tells Victoria Gill how his team pieced together the mammoth's life from isotopic clues captured in the tusk. Also in the programme: The search for storage capacity underground for all the hydrogen we'll need for a net zero carbon economy, with geoscientists Katriona Edlmann and Eike Thaysen of the University of Edinburgh. How the 1987 Montreal Protocol (which phased out CFCs) saved us from an even worse climate crisis than the one we're facing, with climate scientist Paul Young of the University of Lancester. Probiotics may protect corals from death by bleaching, with marine biologist Raquel Peixoto of King Abdullah University in Saudi Arabia.

Victoria Gill talks to climate scientist Friedericke Otto about the Intergovernmental Panel on Climate Change's new landmark report. The report this week states that the evidence for humanity's role in changing global change is now unequivocal. Dr Otto was a lead author on the chapter on extreme weather events and explains how human influence can be attributed to the increasing incidence and intensity of heat waves and heavy rainfall events. Also in the programme: Immunological evidence to support a covid vaccine booster programme in the UK, with virologist Jonathan Ball of the University of Nottingham. Faecal transplants that rejuvenated the memory and the brains of elderly mice, with neuroscientist John Cryan of University College Cork. A website for the public to report their sightings and upload their videos of ball lightning, with electrical engineer Karl Stephan of Texas State University, San Marcos.

Victoria Gill looks at the latest stories from the world of science. In this week's episode: the threat to bees from multiple pesticide exposure, how bee colonies can evolve defences against the varroa parasite, more problems for the Starliner space capsule, and what may be the oldest fossil animals yet found.

In the UK we have seen a recent fall in Covid 19 cases. Good news, but we don’t know yet if this will be sustained. The virus is now thought to be spreading predominantly amongst the under 30s, most of whom remain unvaccinated. Young adults are the demographic most likely to be vaccine hesitant or vaccine averse. Kavita Vedhara from Nottingham University discusses the delicate balancing act of managing personal choice and collective responsibility needed to persuade people to get vaccinated to help stop the spread of the virus. Forget lab rats, how about lab cats? Leslie Lyons from the University of Missouri says we’ve long neglected the genetic similarities between cats and humans. And that understanding how the diseases we share in common affect our feline friends will help with treatments for ourselves. If you take lots of medicines wouldn’t it be great to have them all in one pill? That’s the aim of Ricky Wildman’s project at Nottingham University – a personalised pill that can be 3D printed to order, And we look at the life of Nobel prize winning physicist Steven Weinberg, famed for his beautifully simple explanations of complex science and also his love of a good argument.

Proteomes, the sequences of protein within the DNA of every living thing, are notoriously difficult to model. The usual chemical methods can take months, but a new computational model using the ability of artificial intelligence to learn the complex sequences is able to predict structures within a matter of hours. Thousands of protein structure predictions are now available on a public database for anyone to access. Understanding such proteins is seen as key to treating nearly all disease. It also hold the potential for improvements in fields as diverse as increasing crop resilience to climate change and biodegrading plastic on an industrial scale. Marnie Chesterton speaks with Demis Hassabis from Deepmind which developed the protein structure prediction system, and Janet Thornton from the European Bioinformatics Institute which holds the database. Genetic engineering, the promise and perils, is the subject of a new series with Matthew Cobb on Radio 4, called Genetic Dreams, Genetic Nightmares. He tells us about the dilemmas now faced by researchers who on the one hand have the potential to send terminator genes into malaria spreading mosquitoes – but who are also aware of the huge unknowns surrounding the release of such technology. Extreme weather events are becoming more frequent. Hayley Fowler has been researching the links between weather systems, climate change and the heat and floods we are currently experiencing. And could we reduce the incidence of SARS-Cov2 with a different vaccination strategy? Julia Gog has modelled different scenarios, as the number of infections continues to rise. A strategy to target those who are mixing the most, whether socially or through their employment, may be more effective than one targeting the most vulnerable.

Epidemiologist Julian Peto is advocating mass testing as the key part of a plan to stop the virus spreading. Studies where everyone has been tested have picked up asymptomatic cases. With the addition of isolation and contact tracing this method of testing has been able to massively reduce the spread of the virus. The hope is such a coordinated scheme implemented nationally could help bring the numbers down. There’s a question over which type of test is best to use for mass testing. At the moment many of us do lateral flow tests at home. Although they give instant results their accuracy has been shown to be strongly linked to how well the tests are conducted - hence the need to back up any positive findings with the more accurate PCR test. PCR takes longer and needs sophisticated lab equipment. However a compromise could be to use RT Lamp tests, they are accurate, give results in around 20 minutes, do require a very basic lab, but without the expensive equipment of PCR. A number of RT lamp tests have now been developed for SARS-Cov2. Kevin Fong has been to see the developers of one of them, the OxLAMP test. And with the lifting of restrictions how are you going to judge your own personal risk from Covid? It’s a question that interests philosopher of science Eleanor Knox. She says government mandates on mask wearing and social distancing have allowed us to avoid tricky questions around our own potential risk from the virus and risks our own behaviour might pose to loved ones. Now there’s a lot more to think about in terms of balancing our desires to return to some semblance of normality while levels of Covid infection continue to rise. One area that’s come into sharp focus over lockdown is exercise. Some people have been unable to exercise due to Covid restrictions while others have discovered a whole new interest in moving more. A new book ‘Move’ by Caroline Williams explores the links between brain function, evolution and movement. She says staying active is a fundamental part of what makes us human.

A global project looking at the genomes of over 2 million people has found a number of distinct genetic markers which seem to either make Covid infection more likely or the symptoms more severe. Some of these markers are known to be associated with susceptibility to cancer and lung disease. However the researchers say on their own these genetic factors are not determinants of how sick people will become. Underlying health, age and sex and a range of environmental and social factors are likely more important says Andrea Ganna from Finland’s Institute of Molecular Medicine who crunched the numbers. The Royal Society Summer Exhibition has just opened. And this year its an opportunity for more people to get involved than ever before – the event is taking place online. There are a number of workshops and interactive games. We speak to a couple of the participants. Caroline Orr from Teesside University talks about research using supercomputers to make microbes produce a range of biofuels that could replace petrol and diesel, and Tony Peyton from Manchester University tells us how the electromagnetic properties of materials are bring harnessed to improve mine clearance in former war zones. And we go to another exhibition, the Royal College of Art graduate show, and ask the age old question - is it art ? Students Kukbong Kim and Bahareh Saboktakin show us their work with recycled concrete and 3d printing - which looks more like science to us.

For the first time the gene editing technique CRISPR has been used by injecting the CRISPR instructions into the bloodstream rather than directly into the affected organ. In a trial, six adult patients showed improvements after the treatment was used to prevent the expression of deformed proteins associated with a genetic disease. The hope is this method could treat a range of other genetic diseases, says Megan Molteni from Stat News. In the near future domestic gas boilers may be replaced by heat pumps. However, a district heating system in London is already installing the pumps in a scheme which should see 50% reductions in their carbon emissions. We visited the Citigen site to see how the plan would work, and discussed the potential for domestic heat pump roll out with Simon Evans from Carbon Brief. And why watermelons, wildflowers and pollinating insects can benefit from less attention. Evidence from Florida on how reducing methods associated with intensive farming chime with initiatives here in Britain to replace grass verges with banks of wildflowers. Researcher John Ternest picks up the story.

The Prime Minister has announced his desire for the UK to become a 'science superpower'. A new office within the cabinet to look at science will work alongside existing science strategy and funding structures. So far it's unclear where the responsibilities between the various science policy bodies lie. James Wilsdon, Professor of Research Policy at the University of Sheffield, helps Gaia Vince pick her way through the spaghetti of overlapping organisations and Dame Ottoline Leyser, UKRI Chief Executive, gives her her take of the impact of the reorganisation. A major new trial has been announced into the effectiveness of the drug Ivermectin for the treatment of Covid-19. There's controversy surrounding the drug, which was designed to kill parasitic worms. It showed some promise against the virus in very limited lab studies. For many reluctant to vaccinate these studies seemed to suggest an alternative way to treat the virus. However, regulatory bodies disagree. It's hoped the new study and a range of other wide scale trials will give a more rounded view on the potential if any for Ivermectin as a Covid 19 treatment. Jack Goodman from the BBC News Misinformation Unit has been looking at the controversy surrounding Ivermectin. Scientists researching it have been subject to abuse and in some countries it has been rolled out as a treatment despite the lack of evidence on its effectiveness. There have been reports of a number of cases of Black Fungus in patients with Covid-19 in India. What exactly is this unusual but life threatening fungal growth? Dr Nitin Gupta, Assistant Professor in Infectious Diseases at Kasturba Medical College in Manipal, South West India, explains why this previously rare infection is now on the rise.. Gaia Vince talks to Elena Zavala of the Max Planck Institute for Evolutionary Anthropology, Leipzig, Germany about how she and her team have managed to extract DNA from samples of earth from the Denisovan cave in Siberia. Some years ago fragments of bone recovered from the cave revealed a new hominin species, called the Denisovans. Now DNA analysis of the layers of earth built up over hundreds of thousands of years are painting a picture of the vast variety of early people who used the cave, which included Neanderthals and early humans as well as Denisovans.

Scientists are now looking at the question of third doses of vaccines against SARS-Cov2, and this week the Cov-Boost trial was launched. It’s being run from University of Southampton and is going to be using seven different vaccines, some at half doses, in people over the age of 30 who were early recipients of their two doses. The Chief Investigator, immunologist Professor Saul Faust explains the aims of the trial. Once we've breathed the coronavirus into our lungs, how does it spread through our bodies, despite our immune defences? Remarkably, scientists have managed to film the virus in the act of infecting lung cells and spreading between them. They then added some antibodies and watched what happened. Alex Sigal of the Africa Health Research Institute tells Gaia Vince what they saw. The UK government has pledged to plant some 2 billion trees to help get us to net zero – and that’s an awful lot of plastic casing to be littering the countryside with. A team at the Institute of Making at UCL decided to look at the overall environmental impact of these tree protectors. This is quite a complicated calculation as it involves looking at the entire life cycle of the trees and the plastic, including the carbon and water and energy used. Gaia finds out from Charnette Chau, the life cycle assessment expert on the team, and Professor Mark Miodownik what they found. Across the US, people have been reporting ponds full of dead tadpoles: mass mortality events. It seems that a parasitic infection previously associated with disease in marine oyster populations, may be to blame: severe Perkinsea Infection. The big fear is that it will spread further, to places like Panama in Central America, which has seen such a drastic decline in frog populations that researchers have begun captive breeding some species as “assurance populations” to protect them from extinctions. Tom Richards, Professor of Evolutionary Genomics at the University of Oxford, reports on what he discovered when he went to Panama to see if the infection had reached its precious hoppers.

Should we be vaccinating children in the UK against SARS-Cov 2? Children are rarely seriously ill if they catch Covid but infections mean missed school, and they can pass it onto older vulnerable people. The US, Canada, Israel and Dubai are some places that are already vaccinating the under 18s and Pfizer has recently published data from a trial of its mRNA vaccine in just over 2000 12-15 year olds, showing no safety concerns. Gaia Vince discusses the issue with Professor Beate Kampmann, consultant paediatrician and Director of the Vaccine Centre at the London School of Hygiene and Tropical Medicine. Dengue fever is a widespread tropical disease caused by a virus spread by the Aedes aegypti mosquito. Until now, there’s also been no way of preventing dengue aside from trying to get rid of mosquitoes, which is pretty tricky. Gaia hears from the World Mosquito Programme’s Dr Katie Anders about some positive news from a large trial in Yogyakarta in Indonesia, where mosquitoes infected with a harmless bacteria called Wollbachia, were deliberately released. The researchers found a 77% drop in cases of dengue in the areas where the infected mosquitoes were released. Hospitalisations were 84% lower. This week the first attempt to map algal blooms globally has been released, and it also charts how blooms have changed over the last thirty years. And the news isn’t good. Henrik Enevoldsen of the UN who’s based at the University of Copenhagen, has spent thirty years studying these phenomena and he explains how the growth in aquaculture has had an impact on the rise of algal blooms in some parts of the world. Nearly twenty years after Concorde last flew, a company called Boom is promising to bring back supersonic passenger flights in the next few years. They say it’ll all be environmentally sustainable. The company has sold some new jets to the US airline United. Gaia talks to Dr Guy Gratton, an engineer and pilot at Cranfield University, about how green supersonic flight can be.

Sars Cov2, as the Covid19 coronavirus is called, probably began as the vast majority of new diseases do, when an animal virus infected a person – perhaps in a market or farm. There’s a large animal market in the city of Wuhan that sold wild as well as farmed animals, and studies have shown that different species of animals can infect each other with coronaviruses on their journey to market. But there’s also a possibility that the virus originated in one of two government laboratories in Wuhan. After all, we know that other viruses have escaped from labs, including the original Sars virus, which escaped multiple times from different Asian labs. Jonathan Ball, Professor of Virology at the University of Nottingham, discusses with Gaia Vince why the lab leak theory is again in the news. We know that obesity runs in families but because parents and children live in the same environment and eat the same food it is difficult to tease out how much of this relationship is inherited genetically. Researchers at Cambridge University have been working with the Children of the 90s cohort of people based in Bristol, and they’ve have found that a mutation in a single gene drives obesity in some families. The gene in question is called MC4R. Professor Stephen O’Rahilly, who is one of the researchers, explains that the mutation is remarkably common and has a significant impact on individuals, from an early age. Last week, researchers released the biggest and most detailed map of how matter and dark matter have spread across the universe since the Big Bang. The problem, is that the dark matter is more smoothly distributed than expected according to Einstein’s theory. Some are now saying physics is broken. Was Einstein wrong? Astrophysicist Catherine Heymans, who is a Dark Universe expert, and has just been appointed Astronomer Royal for Scotland, the first woman to hold the role, talks about the implications of the new map of dark matter and her plans to encourage the public to appreciate the night sky. For the first time figurative rock art over 4000 years old has been discovered in Scotland. Up till now all that’s been found have been marks such as cups and rings. The new images are detailed portraits of deer, with antlers, on a capstone of a burial mound, or cairn, in Kilmartin Glen on the west coast. It’s a well-studied archaeological site but the rock art hadn’t been spotted before. Gaia asked Tertia Barnett, Principal Investigator for Scotland’s Rock Art Project at Historic Environment Scotland, about who may have produced this art.

Human impact on planet earth’s plant life might be detectable several thousand years back in fossil pollen cores taken from mud columns around the world. As Suzette Flantua and Ondrej Mottl describe in a paper published in the journal Science, a rapid acceleration in the changes in pollen species goes back further than we might have expected. This matters particularly when it comes to decisions around re-wilding and re-planting areas today in the name of conservation. As they hope to build on in future work, learning more about the state of ecosystems further back into the past might prevent us making the mistake of simply recreating different types of post-agricultural situations which might not solve the problem we are trying to fix. One of the biggest impacts on the earth’s flora today is of course influenced by our meat consumption. The BBC’s Melanie Abbott has been to see a new exhibition opening at Oxford University’s Musuem of Natural History. Produced in association with the University’s Livestock, Environment and People research programme, this exhibition “Meat the Future”, seeks to raise awareness of the issues for health and the environment around eating – or not eating meat - and is open until January 2022. At the same time, a travelling interactive experience called Meat Your Persona will be moving around the UK, starting in Cardiff. And there's an online interactive questionnaire you can try from home. See the links at the bottom of the BBC Inside Science programme page. Researchers in the US are working on devices that might be able to connect with people’s brains to allow them to manipulate robotic or digital devices to regain abilities lost to disease or injury. As Dr Frank Willett and Prof Krishna Shenoy - both at Stanford University’s neural prosthetics translational laboratory - describe in the journal Nature, they have managed to create a device that allows one patient to create text using just thought. Rather than trying to guide a cursor over a keyboard, their technique works by learning which letter the patient is thinking of drawing by hand, despite being unable to wield a pen. And Jacob Dunn, associate professor at Anglia Ruskin University describes his team’s work which finds that tamarin monkeys will use the “accent” of another species when they enter its territory to help them better understand one another and potentially avoid conflict. His paper, published in the journal Behavioral Ecology and Sociobiology, describes findings in the Amazon rainforest near Manaus where a species that ordinarily use quite distinct long distance calls subtly change their call to sound more like a neighbouring species’ equivalent call when they are sharing the same area of forest. Not so much an aggressive intrusion as a polite lingua franca, it may be that the shared understanding reduces unnecessary and costly territorial fights between the two species.

Vic Gill talks to scientists who have cured a vaccine-induced blood clot patient, and meets a former top F1 chief engineer who wants to transform the fuel industry. Scientists in Vienna have been continuing to look at the rare blood clots associated with the AZ Covid-19 vaccination. Paul Knoebl describes to Vic his paper describing the diagnosis and successful treatment of a patient who developed a fever whilst skiing six days after taking it. Whilst the side effect is still condsidered incredibly rare, Paul tells Vic that a relatively simple cure - after early diagnosis - should remove any lingering hesitancy of taking a vaccine. The Science Museum reopened this week with a new exhibition looking at the science of Carbon Capture. Inside Science took former Formula One technical champ Paddy Lowe to have a look round. He is interested in Carbon Capture because he has started a new company - Zero Petroleum - that aims to do nothing less than kick start a synthetic (hydrocarbon) fuel revolution. Using carbon dioxide captured from the atmosphere, he and colleague Prof Nilay Shah believe they can use renewable electricity and other feedstocks to tranform captured carbon into fuels, and create a whole new petrochemical supply that could close the loop on the industrial revolution - especially for those energy uses where batteries could not currently work, such as jet engines and heavy remote machinery. Meanwhile, up in the north east of England, Charlotte Adams of the UK's Coal Authority describes progress on measures to convert disued Coal mines to geothermal heatpumps, providing reliable steady heating for new-build homes across many parts of the UK, and taking strain off the elictircal grid. Presenter Victoria Gill Producer Alex Mansfield

Untreated wastewater "routinely released into UK rivers" is creating microplastic hotspots on riverbeds. That is the conclusion of a study in Greater Manchester, which revealed high concentrations of plastic immediately downstream of treatment works. The team behind the research concluded: untreated wastewater was the key source of river microplastic. Jamie Woodward takes Vic Gill wading in the River Tame in Greater Manchester to show some of the sites they studied, while co-author Rachel Hurley talks from Norway on the wider global questions of where microplastics get into our environment and what harm they do. The origin and location of the radioactive pollution that so devastated the lives and livelihoods of those affected by the Chernobyl disaster 35 years ago is not a mystery. But recently it has become apparent that in one small inaccessible room within the massive sarcophagus at the ill-fated power station, the nuclear fission still happening is getting slightly faster. As Neil Hyatt describes to Vic, the reason may be because the new concrete shell, unlike its predecessor, is doing a better job at keeping the rain out, and nothing to worry about for the time being. Meanwhile, Jim Smith and colleagues have been trying to demonstrate that agricultural products could help the besieged economy of surrounding areas. Using apples grown in regions where investment is illegal, they have developed a spirit drink - called Atomik - with which they hope to demonstrate a viable market outside of the Ukraine, perhaps providing jobs and export business, and maybe even useful profit with which to help the area. And finally, Dr Kim Dienes describes from Swansea the health and psychological benefits of something so many hundreds of millions of people in the world have been missing this year: a nice hug. Presenter: Vic Gill Producer: Alex Mansfield Assistant Producer: Samara Linton.

Despite being home to our early ancestors, attempts to find evidence of early burials in Africa have proved unsuccessful. That is until now. Professor María Martinón-Torres explains how findings from a 78,000-year-old Kenyan grave shed light on how our ancestors related to the dead. In keeping with the theme of clues from the past, Cardiff University academics have been studying the remains of crew who drowned on King Henry VIII’s favourite ship, the Mary Rose. As it turns out, Tudor England was more ethnically diverse than we previously thought. Victoria Gill speaks with University of Oxford researcher Dr Mehreen Datoo about a promising new malaria vaccine which was shown to be 77% effective in early trials. And Dr Nir Grossman, explains how his team at Imperial College London has been synchronising electrical pulses with rogue brain waves to treat tremors.

Now that NASA engineers have successfully flown a helicopter remotely on Mars planetary scientists are exploring how to use the technology elsewhere. Marnie Chesterton talks to Elizabeth "Zibi" Turtle, from Johns Hopkins University who is working on a mission to fly a drone, called Dragonfly, above Titan, one of Saturn's moons. A new report that has measured the state of over 200 000 of the world's glaciers has just been published. Bob McNabb of the University of Ulster explains why it's not good news as glaciers are melting at a faster pace than before. He says it could have a particular impact on people who live in low lying areas. At the start of April cases of the South African variant of SARS-Cov 2 were found in a number of London boroughs. In order to stop the further spread of these variants, a programme of surge testing was announced. It’s just come to an end and Marnie finds out from Public Health England’s regional director for London, Professor Kevin Fenton, how it worked. Birds aren’t very good at adapting to human additions to the landscape, particularly tall buildings. Could extra sonic elements - so-called acoustic lighthouses - help? From William and Mary University in Virginia, Timothy Boycott and John Swaddle joined Marnie to explain how these can make a difference.

This week has seen a huge surge in Covid- 19 in India leading to concern of a "double mutant" variant, but what do we know about this B.1.617 as it is otherwise known. It was first described in October and is now in other countries including the UK. Virologist Dr Muge Cevik looks at the emerging evidence around vaccines and new variants. Climate change threatens coffee crops so it's exciting to know that researchers have found an ancient coffee variety that is drought resistant and can tolerate higher temperatures than the highly prized Arabica coffee used to make your latte - but it wasn't easy to find. In Sierra Leone Daniel Sarmu spent 4 years searching for it and Dr Aaron Davis from Kew helped to track it down using historic samples from the Herbarium at the Royal Botanic Gardens. Clothes moths do enormous damage to our jumpers and carpets, Marnie finds out how best to protect your clothes. And we hear from Mark Miodownik about the right to repair.

The story of what we understand about the rare cases of blood clots associated with certain Covid-19 vaccines is constantly evolving. In today’s programme Professor Beverley Hunt looks at the emerging evidence. How have the restrictions due to Covid 19 affected how we grieve? Professor Claire White, an expert in grief and mourning, is investigating what it means to the grief process when the traditional ways of acknowledging death are changed. Sascha Fruholz has the unenviable task of listening to people scream all day, but he has made some surprising discoveries about which types of scream people are best able to identify.

In 2016, an accelerator physics centre called Fermilab acquired a massive circular 50 foot magnet from a lab in New York. Too big for the roads, the magnet had to take a 2000km detour via New Orleans to get to its new home. This was the start of the “muon g-2” experiment. Last week, Fermilab announced some of their results, and they don’t quite add up. UK experiment lead Professor Mark Lancaster from Manchester University tells us what they have discovered about the tiny particle that is disobeying the laws that govern how our entire universe fits together. Mountain gorillas are among the most impressive and powerful primates alive today. Living in the dense forests of eastern and central Africa, they are able to communicate with other gorillas a mile away by cupping their hands and beating their chests. Primatologist Edward Wright and colleagues have been studying male silverback gorillas and explains how gorillas use chest beating to attract potential mates and suss out competitors. And Professor Corey Bradshaw from Adelaide, South Australia sheds light on a more fearsome animal: sharks. His research has investigated the likelihood of shark attacks around the Australian coast into the future, up to 2066, and asked what would happen to those figures if everyone wore an electrical emitter that interferes with the sharks electrical senses. He finds that shark attacks are remarkably low already, but these emitters could reduce bites by up to 3000 over the next 50 years. Super fans around the world have learned to speak fluent Klingon, a fictional language originating from Star Trek. In a quest to understand the science behind these languages often dismissed as gobbledygook, Gaia Vince has been speaking to some of the linguists responsible for creating these languages. It’s time for her to relax the tongue, loosen those jaw muscles and wrap her head around the scientific building blocks embedded in language and what languages like Klingon tell us about prehistoric forms of communication. Presented by Marnie Chesterton Produced by Rory Galloway

Scientists were delighted earlier this year to find they would still have access to the EU Horizon 2020 funding and collaborations. Now, it has been revealed that membership of this group, which was previously paid for through fees to the European Union, may come directly from the science budget, at a cost of about £15 billion over the next 7 years. That’s £1-2 billion a year. Marnie Chesterton speaks with Beth Thompson, head of policy at the Wellcome Trust about the implications, and Roland Pease asks scientists working around the world how the previously announced ODA cuts are affecting their work. Native oysters help to filter coastal waters of the UK of pollutants including nitrates, while also providing habitat for other species. But their numbers have declined by 95% throughout their British range. Now, the Zoological Society of London is placing thousands of mature oysters under pontoons in marinas across the UK to let them breed, and encourage the return of the species to their former numbers. And the new coronavirus mutations that are worrying us all have been found to affect mice in experimental studies at the Pasteur Institute in France. Marnie asks if this change to the infectivity of the new variants has implications for human health and our ability to combat the virus. Presented by Marnie Chesterton Produced by Rory Galloway

The UK is reportedly halfway towards meeting its 2050 target of "net zero" carbon emissions. How did we get there and how will we achieve the next stage? ‘UK greenhouse gas emissions in 2020 were 51% below 1990 levels, according to a new Carbon Brief analysis. This means the UK is now halfway to meeting its target of “net-zero” emissions by 2050.’ Simon Evans explains his predictions from the report, outlines how we define net zero and what is required from the next few decades to ensure that the UK meets its 2050 goal. Much of Europe is attempting to replace fossil fuels, transforming transport and domestic heating to run on electrical alternatives, such as batteries and heat pumps. But where electrification isn’t possible or cost effective, such as in many homes, an alternative is still needed. Natural gas is responsible for over 30% of the UK’s total carbon emissions. Hydrogen would, theoretically, appear to be the perfect alternative, as combustion only produces water as a by product. Gaia discusses the options with hydrogen strategist, Dr Jenifer Baxter, and Dr Angela Needle of Cadent explains the pilot projects the company is carrying out to introduce 20% hydrogen into gas going into our homes. Last Friday, Fragradalsfjall began erupting for the first time in 800 years. The volcanic system is located in the West of Iceland close to the capital city of Reyjkavik. Dr Evgenia Ilynskaya of Leeds University has been out measuring the gases emitted by the eruption and she describes the experience of working on an active volcanic system.

We still know very little about exactly how the embryo forms out of a mass of dividing cells in those crucial first weeks after conception. This is also the time when many miscarriages occur, and scientists want to understand why. Couples going through IVF donate spare embryos for research and scientists are permitted to study them in a test tube, or in vitro, allowing them to grow and develop for up to 14 days. This 14 day rule is abided by globally, and it’s enshrined in the Human Fertilisation and Embryology Act in the UK. Thirty years ago no-one could keep these embryos alive for more than a few days but recently the techniques have moved on and they have been cultured for nearly 14 days. So should the 14 day rule be extended? Gaia Vince discusses this question with bioethicist professor Insoo Hyun of Case Western University and Harvard Medical School. There are other ways of studying this early development that don’t involve growing an actual embryo, and that’s by using just a few stem cells from it. These are cells that haven’t yet specialised into any type of body cell and so they have the potential to become any cell type. Researchers can grow these cells into structures that resemble embryos, although they could never survive inside a woman’s womb, and these artificial embryos aren’t subject to the 14 day rule. Gaia talks to Dr Naomi Moris of the Crick Institute in London about her work on what she calls gastruloids. Whaling was a huge industry in the 19th century, and populations of sperm whales plummeted, as hunters sought the oil in their heads that was used everywhere for lighting. The whalers who were hunting in the North Pacific kept meticulous records that have been recently made public. Biologists have been studying them, and picking out unexpected changes in the patterns of whale capture. Dr Luke Rendell of St Andrews University explains how he and his colleagues worked out that that the whales seemed to be learning from each other how to avoid the boats. A piece of intricate Ancient Greek engineering called the Antikythera mechanism, that was found by sponge divers in 1901 in the Mediterranean, has fascinated many people. Last week a team from University College London published the latest explanation of how the device worked. Science writer Jo Marchant herself became so obsessed with the mechanism that she published a book on it called Decoding the Universe and she talks to Gaia about the object and what the new research tells us about how the Greeks understood the cosmos two thousand years ago.

On Friday 5th March China published a draft for its 14th five-year plan in Beijing. The document acts as a national economic blueprint and was expected to provide an outline as to how the world’s biggest emitter of greenhouse gas emissions planned on tackling its target of reaching net zero emissions by 2060, put forward by President Xi Jinping last September. It appears that greenhouse emissions could continue to increase by 1% or more each year up until 2021. Sam Geal, acting CEO at China dialogue, explains how influential Chinese efforts are when combatting climate change. Since the late 1980s conservationists have used captive breeding to prevent the extinction of North America’s only native ferret species, the black footed ferret (Mustela nigripes). Now, an individual called WIlla, who died without leaving any offspring over 30 years ago has been cloned. Her genes represent 300% of the current genetic diversity of the species, and could help boost the chances of these animals. Dr Bridget Baumgartner works with one of the teams that took part in the successful cloning project, she describes how this novel process could bolster and prop up the genetic diversity of the dwindling population. How does one get a closer look at nutrient cycling and water temperature in marine Antarctic conditions? You could always recruit some of the local inhabitants, elephant seals! That’s exactly what Yixi Zheng at the University of East Anglia did. Her furry research assistants have revealed that surface water temperatures around the ice shelves and glaciers of Antarctica are warmer than expected in winter, and this holds implications for nutrient cycling and the productivity of the southern ocean. And finally, after an ancient rock seized the attention of the residents of Winchcombe in Gloucestershire, Professor Sara Russel discusses the rarity of finding meteors here on earth, let alone finding one early in the morning sat on your driveway. We hear what the nearly 400g of space rock that's been found this week could reveal about the origins of our solar system.

With global warming continuing to increase at an alarming rate, we need all the help we can get to lock up the carbon that we’ve released into the atmosphere. Fortunately, plants have evolved to do just this, but there’s a whole class of plants that often get forgotten: the mangroves and seagrasses that grow between land and sea, which are among the planet’s most effective carbon sinks. Gaia Vince talks to Fanny Douvere, head of the marine programme at UNESCO, about its new report that shows the importance of blue carbon locked up in its marine World Heritage Sites. And Professor Hilary Kennedy, of Bangor University, explains why seagrasses are so effective at locking up carbon. Roland Pease reports on the secret journey made by one of the most valuable of human fossils, Little Foot, from Johannesburg to Oxfordshire, where it was scanned at the Diamond Light Source facility – one of the most powerful X-ray machines in the world. He talks to some of the main players about the hush hush voyage, and what they’re hoping to discover. There are few things more intriguing than an unopened letter, but what about one from 300 years ago? The Brienne Collection is a Postmaster's trunk containing more than 2000 letters sent to the Hague between 1680 and 1706, and more than 600 are still unopened. In the days before envelopes, people used elaborate folding techniques to secure letters, even tearing off a bit of paper and using that to sew the letter shut, effectively locking it. It makes reading those letters very tricky indeed, especially as antiquarians don't want to risk opening them. Instead, researchers hatched a plan to scan the letters in their untouched, still folded state, and generate a 3D image of their insides of such detail it could be used by an algorithm to unfold it virtually. David Mills from Queen Mary University London tells Gaia about how he used a microtomography scanner to peek inside the unopened letters. Presented by Gaia Vince.

On Thursday, The UN Environmental Programme published a report called Making Peace With Nature. It attempts to synthesise vast amounts of scientific knowledge and communicate “how climate change, biodiversity loss and pollution can be tackled jointly within the framework of the Sustainable Development Goals”. But it also offers clear and digestible messages that governments, institutions, businesses and individuals can act upon. Concluding BBC Inside Science’s month-long look at some of the challenges ahead of COP26 in Glasgow later this year, and its sister biodiversity meeting in China, Vic speaks with the report’s co-lead Prof Sir Robert Watson FRS and the Tyndall Centre’s Prof Rachel Warren, also a contributing author. Can all the ills of the natural world really be tackled at once? Game-shooting, for sport and food, has traditionally used the toxic metal lead for ammunition. In other parts of the world its use has been banned for the dangers to the human food chain and to the pollution in natural environments, and even deaths of wildfowl from poisoning. But not so in the UK. A year ago, as reported on Inside Science at the time, the shooting community announced a voluntary five year transition period to alternative shot materials. But researchers including profs Rhys Green and Debbie Pain from Cambridge University have discovered that a year on, little seems to have changed. Gathering game sold for food across the UK, they found that all but one bird in their sample of 180 contained lead shot. Meanwhile, up in the Himalayas, Smithsonian scientist Dr Sahas Barva was enjoying the scenery on a cold day off in 2014 when he saw and heard a tiny Goldcrest, thriving in temperatures of -10C. Wondering how such a tiny thing could keep its body insulated, he decided to investigate feathers, and utilizing the huge numbers of specimens in the Smithsonian’s collection he found some striking commonalities in the thermal properties and adaptations of birds everywhere. The higher up they live, the fluffier their coats. Presented by Victoria Gill Produced by Alex Mansfield Made in association with The Open University.

On Thursday 18th Feb 2020 Nasa’s Perseverance Rover is due to touch down – gently and accurately – in the Jezero crater on Mars. Using similar nail-biting Sky Crane technology as its predecessor Curiosity, if successful it will amongst many other things attempt to fly the first helicopter in the thin Martian atmosphere, and leave small parcels of interesting samples for future missions to collect and return to earth. Unlike previous Martian landings of course, there are no mass-landing parties to be held because of Covid. So Vic Gill invites you to join her and current Curiosity and future Rosalind Franklin (ESA’s 2023 Rover) team scientists in nervously awaiting the signal of success. Dr Susanne Schwenzer was so tense during Curiosity’s final approach in 2012 that she managed to draw blood from her own hand from clutching her mobile phone too hard. BBC Inside Science expects nothing less this time round. Dr Peter Fawdon has been part of the team seand examining the landing site for ESA’s Martian lander and Rover, currently slated to launch in 2022. The project has had a complicated history, having been delayed several times. But with so much at stake, it’s worth getting right. Meanwhile, at Liverpool University, computer scientist Dr Maya Wardeh and virologist Dr Marcus Blagrove have been collaborating to see if Machine Learning and AI can help predict which mammalian species are more likely to harbour the next big coronavirus. Pitting traits and genomes, species similarities, lifestyles and ecosystems of mammals and viruses, they highlight in a paper published in Nature Communications some of the potentially most potent combinations where different coronaviruses could meet and spawn a new breakout. Not just looking for the more quotidian viral mutations the world is increasingly and unfortunately aware of, they have been looking instead for those species where something called homologous recombination between two different viruses, producing a third completely novel type, may occur. It turns out there are many possibilities beyond just bats, which are highly suspected of being the crucible in which SARS-CoV2 was smelted. To spot whatever comes next we should keep an eye on camels, rabbits, palm civets and even hedgehogs, according to the algorithm.

Victoria Gill and guests discuss the signs and symptoms of melting ice and anthropogenic climate warming, illicit CFC production and the racket we make in the seas. As two robotic missions from UAE and China arrive at Mars , and a third from NASA arrives next week, UK astronaut Tim Peake talks of the international collaboration in Mars research that is to come. And continuing BBC Inside Science's look at some of the issues facing COP26 delegates to Glasgow this autumn, Victoria is joined by cryosphere scientist Dr Anna Hogg, Anna studies – sometimes from space - how polar and Greenland ice sheets are melting and shifting as our climate warms. But those giant volumes of ice and concomitant rising sea levels might not be the only threat to people’s lives. It may be that the recent deadly flash flood in India was a result of a swiftly melting Himalayan glacier. The Montreal treaty - prohibiting the production of CFCs to allow the man-made polar hole in the Ozone layer identified back in the 1980s to repair - has long been cited as the classic example of an effective international agreement to protect earth's environment. But just a few years ago in 2018 Luke Western and colleagues identified not just that CFC production was suddenly and unexpectedly rising, but that it was mainly emanating from an area in eastern China. It was speculated then that their use in foams for buildings was happening illicitly on a large scale. This week, they happily announce that those emissions seem to have ceased, and that the target of a healthy ozone layer is back on track. The oceans are, since man first took to the waves, a noisy place. In a comprehensive paper published last week in the journal Science Carlos Duarte and colleagues describe how huge an impact the many anthropogenic noises that echo for miles across the sea beds have on virtually all aquatic life. He argues that it is one stressor, rather like CFCs, that we could and should take swift and effective action to address, that the time for that is ripe, and that doing so will see a swift rebound in many aquatic ecosystems. Humans are not naturally adapted to hear the noise underwater, but to illustrate the point, co-author digital artist Jana Winderen has made an acoustic demonstration for your benefit, of quite how noisy neighbours we are Also, for listeners on BBC Sounds, the BBC's Roland Pease gives an update on where and how scientists think the covid-19 epidemic began, after a WHO team of scientists report on their recent mission to Wuhan and the infamous market. As Roland and WHO delegate Peter Daszak surmise, we still don't quite know, but it wasn't in a lab. Presented by Victoria Gill Produced by Alex Mansfield Made in Association with The Open University.

Ahead of the COP summit in Glasgow at the end of the year, this week an important study was published that attempts to enumerate the value of biodiversity in the economics of humankind. Prof Sir Partha Dasgupta's review makes it clear how essential and yet vulnerable it is. Trees play a large part in the biosystems of the planet, and replanting them is often touted as a solution to many of the carbon challeneges of the next century. But a paper and forthcoming conference hosted by Kew points out just how carefully reforestation - let alone afforestation - must be conducted. Kew tree expert Kate Hardwick tells Victoria about their 10 golden rules of planting trees. In a forest in Borneo, trees have been planted that will extract the high levels of Nickel from the local soil. It is hoped that the biomass from the trees can then be used to harvest the nickel. It is an attempt to commercialize successfully the dreams of "phytomining" - finding specific crops or traits in plants that can act to "hyperaccumulate" minerals and metals from soils. BBC Inside Science's Harrison Lewis reports how, after some intrepid botany, the idea might just now be bearing heavy fruit. But finding the plants that do some of what you want them to does not mean they should be planted just anywhere. Lulu Zhang from United Nations University in Dresden, Germany tells Victoria about the Chinese experience of a few decades ago when the Black Lotus tree seemed to be just the ticket for newly foresting huge areas of China to stabilize and neutralize soils. Unfortunately, nobody realized how thirsty the monocultured forest would be, and the thirsty trees deprived the area of much of the rainwater from humans and agriculture. Meanwhile this week scientists have published work looking at how even the noise from traffic on the roads can disrupt animal behaviour. Chris Templeton of Pacific University in Oregon has been studying how some bird's cognititve abilities can be affected. And Adam Bent describes work at Anglia Ruskin University into how crickets' mating choices can be adversely affected by recordings of the A14 near Cambridge.

A year after the first SARS-Cov2 sequences were received in the vaccine labs, Dr Alex Lathbridge and guests look into ongoing development and what next year's booster shots might be like. Prof Robin Shattock's team at Imperial College are still working on their vaccine technology - called 'Self Amplifying RNA' or saRNA. A little bit behind their well financed corporate colleagues, this week they announced that instead of pressing ahead with a phase III trial, they will instead look to developing possible boosters and alternative targets just in case more and more serious mutations happen. But as Prof Anna Blakney explains from her lab at University of British Columbia, the possibilities of saRNA don't stop with coronaviruses. Researchers in the journal PNAS report this week a new theory as to when and where dogs were first domesticated by humans, and suggest that they accompanied the first humans across the Bering straight into America. Inside Science's Geoff Marsh has a sniff around. And Dr Dean D'Souza from Anglia Ruskin University describes in Science Advances work he has done looking at certain kinds of development in children who grow up in bilingual households. His work suggests a slightly faster and keener observation of detailed changes in visual cues, and that this seems to be a trait that survives into adulthood.

Reports this week talk of some BAME ethnic minorities being significantly less likely to take a covid vaccine if offered. Vittal Katikireddi and Tolullah Oni both sit on the SAGE ethnicity subgroup, and they discuss with Alex Lathbridge where the figures come from and quite what they might mean. Some of these same groups have suffered some of the worst outcomes from infection. Addressing any underlying problems that bely the figures will take a nuanced approach. Researchers in Japan and Liverpool have been investigating cat's prediliction for the herbs Catnip and Silver Vine. It turns out that there may well be a deep evolutionary reason they have evolved to love rubbing it in their fur so much: a key ingredient is a good mosquito repellent. As Professors Masao Miyazaki and Jane Hurst describe. It could help keep the mozzies away but you might end up being tailed by cats. And researcher Iestyn Woolway of the European Space Agency Climate Group, at Didcot UK, describes his work modelling the world's lakes' reaction to a warming climate over coming decades. It's not very comforting, with increased duration and intensity of what he calls "Lake Heatwaves". Presented by Alex Lathbridge Produced by Alex Mansfield Made in associataion with the Open University. Note: This podcast has been edited since the original broadcast to prevent any possible inference that the Tuskegee syphilis study involved the deliberate infection of subjects. In the Tuskegee study, African American patients who were already infected with syphilis had diagnosis and treatment deliberately withheld from them in order to observe the progression of the lethal disease over several decades (even after a perfectly simple treatment - penicillin - became available).

In the new EU-UK deal, the UK is to be an associate member of the latest EU research funding round, known as Horizon Europe. Costing around £2bn to take part, what can UK scientists now do and what has changed? UKRI CEO Otteline Leyser and the Wellcome Trust EU specialist Beth Thompson discuss ways in which UK researchers are breathing a sigh of relief. Of all the ways the UK can now diverge from the EU, DEFRA is currently holding an open consultation on whether to tweak the current GMO regulations so as not to include CRISPR-style Genetic Editing. The EU is coincidentally looking at the same issue. John Innes Centre's Janneke Balk works on making strains of wheat that have a higher level of iron for nutritional fortification. Interim head of the Roslin Institute in Scotland Bruce Whitelaw thinks developing disease resistance in farm animals is a potentially profitable area. Both agree the GMO regulations should be more tightly specified to bring clarity and opportunity for innovation. In Iceland, Kari Stefansson's company Decode Genetics analyze the genetic codes of most of the population of Iceland. This has allowed them to look at the parents, siblings, and offspring of identical twins, and identify how early genetic differences between them develop. And it's very early indeed. Given that identical twins studies are so often used to address issues surrounding the so-called Nature-vs-Nurture debate, the findings, published in the Journal Nature, are striking. Presenter by Marnie Chesterton Produced by Alex Mansfield Made in association with the Open University.

After the decision by the UK government last week to change the spacing between dosings of vaccine from the recommended 3 weeks to 12 weeks, immunologists around the world have been discussing with some urgency the wisdom of such a move. The FDA and the WHO are deeply sceptical, and the manufacturers have distanced themselves to some extent, by cautioning not to deviate from the regime tested in last year's phase III trials. The thinking behind the move is to get more people injected with a single dose in a shorter time, and that the longer wait for the second shot is worth the risk, if it means more people receive some level of protection in the short term. Clinical Epidemiologist Dr Deepthi Gurdasani and Immunoligist Prof Danny Altmann of Imperial College describe to Marnie how evidence, experience and hunch are combining in the face of the covid crisis, and quite what we know, what we don't and what we could, about this nationwide experiment. Increasingly, ecologists wanting to monitor remote areas are relying on such things as solar powered audio recorders to measure biodiversity in the sounds of the wild. But how to scrutinize years and years worth of 24 hour, multi-site recordings? Sarab Sethi and colleagues have not only been leaving solar-powered Raspberry Pi recorders out in the jungles of Borneo, they've been using machine learning techniques to look out for species and biodiversity changes from afar. You can listen to some of the Borneo work at the SAFE acoustic website (link on BBC page below).

As a new decade ticks over, Dr Adam Rutherford, Professor Alice Roberts and Professor Brian Cox look back on a decade of science that has transformed perceptions of our medicine, our history and our universe. From advances in genetics that have brought personalized medicine to reality, and revealed the ghosts of ancestral human species never before identified, to quantum computing lessons that hint at the nature of existence and causation throughout the universe, it has been an interesting time. New observational technologies have revealed fresh windows in time and space. And all of it has been reported by BBC Inside Science. But what of the next decade? Programme may contain traces of informed speculation, but (almost) no references to Covid. Presented by Adam Rutherford Produced by Melanie Brown Made in association with The Open University.

Nobody could have failed to notice the one story dominating the science news this year - but what about the discoveries that have been overshadowed in 2020? This week, Dr Adam Rutherford eschews all mentions of the pandemic as he invites dinosaur researcher Dr Susie Maidment, climate scientist Dr Tamsin Edwards and astrophysicist Dr Emma Chapman to share their science highlights of the year. We journey to the moon and beyond to discuss the many missions that have been blasting and grabbing bits of space rock to bring back to earth and tackle the ongoing debate about whether signs of life have been found on Venus. Back down on earth, this year could be one of, if not the, hottest years on record, with particularly high temperatures in the Arctic Circle. What might a warming world mean for ice-shelf collapse in Antarctica and how are governments responding? We discuss Joe Biden’s presidency, UK carbon emissions and what China’s recent announcements of net zero by 2060 might mean for the future of the planet. And despite limitations on travel this past year, exciting discoveries in the dinosaur world have nonetheless continued with what is believed to be the first aquatic dinosaur. The detection of soft shell eggs is also changing understandings of how dinosaurs reared their offspring. And if that wasn’t enough, Dr Adam Rutherford challenges our experts to predict what big science stories might lie on the horizon in 2021.

Dr Alex Lathbridge with your peek at the week in science. This week in the House of Commons Matt Hancock announced a new variant in the Covid virus, discovered to be spreading through the south east of the UK. As Professor Jonathan Ball of the University of Nottingham describes, there have been many slight mutations and changes to the DNA in the virus since it first emerged, and most are of no added danger. But it is important that new ones - and new combinations of them - are tracked through collaborations and networks such as COG-UK, who provide an almost real-time track of the spread of new mutations. The new one this week is of some interest as it involves a slight change to the protein of the binding area on the virus, but much lab work remains to be done, Is an angry face always an angry face? A paper in the Journal Nature this week uses Machine Learning to scan millions of videos of faces on YouTube to shed light on an old problem - the universality of facial expressions in people. The authors - working with Google - suggest that broadly speaking, in a number of contexts such as weddings and sporting events, people in much of the world tend to pull the same faces. But as Lisa Feldman Barrett - who wrote an accompanying commentary in the same journal - suggests, the way Machine Learning approaches in this area require very human perceptions to train the algorithm in the first place, means care must be taken before inferring too much. This year BBC Inside Science has been showcasing some of the mystery objects the Science Museum has uncovered in the course of moving its collections to a new home in Wroughton, Wiltshire. Jessica Bradford talks to Alex about our next one.

Dr Alex Lathbridge brings you the week in science. As the first COVID vaccines are delivered this week hastening the first glimmers of a return to normal life, is it too soon to be thinking about other future threats to humanity? James Arbuthnot, chair of a House of Lords select committee tasked to look at risk planning, and fellow committee member Martin Rees discuss their meeting this week and the assessment of the scientists invited to share their interpretations of future threats like AI, solar flares and volcanic eruptions. They are inviting evidence submissions until January 28th 2021. The Millennium Seed Bank was setup as a safety net to protect and conserve rare, threatened and useful wild plants for generations to come. As it celebrates 20 years of operation it can claim to host 16 per cent of the world’s bankable flora in its sturdy underground vaults. Alex heads down to the Royal Botanic Gardens in Wakehurst, Sussex, and meets the team coaxing seeds to life to check their viability or using cryopreserving on those seeds less convivial to being preserved. One key project is protecting farmed crops that have lost genetic diversity over time and are at risk from climate change. Through collecting and researching the wild ‘cousins’ of our modern day crops Wakehurst, Kew Gardens and its partners are researching and harnessing the resilient traits found in these less pampered crop relatives. Treezilla.org is a citizen science project designed to increase understanding of all the urban tress in the UK. Scientists, together with the public, are getting their tape measures out and cataloguing the trees to better ascertain how they influence the environment in towns and cities across the UK, to map their ages, species, sizes and health, and to help future planners to put the knowledge to work. Kate Hand is a researcher at the Open University who is looking at ways to increase our knowledge of the values trees bring to our urban environments – specifically through the lens of Milton Keynes which, it transpires, is quite the urban arboretum.

Has one of the biggest problems in biology been solved by AI? Dr Alex Lathbridge brings you the week in science. This week google's Deep Mind team presented results of their latest efforts at cracking the 50 year old problem of Protein Folding. AlphaFold has built on previous success at predicting the 3D structures of biological proteins from just knowing the sequence of amino acids of which it is made. It is a computational problem that thousands of researchers around the world have been trying to solve for decades. There are millions of different proteins doing all the work in living cells, but simply knowing what their constituent chemicals are is not enough to understand how they are shaped, and therefore how they work. Scientists are optimistic that solving the problem will herald a new era in medicine, agriculture and even sustainable recycling. Prof John Moult, founding chair of CASP - the international body that monitors progress in the field, tells of the remarkable breakthrough being discussed this week. Whilst China is trying to bring back samples of the moon this week, a much longer-lived space mission to an asteroid hopes this weekend to return samples of the earliest bits of the solar system to earth. Hyabusa 2 will complete a 6 year mission, Japanese scientists hope, this weekend when a small package of asteroid sample drops into the atmosphere above Australia on Sunday morning. And as students across the UK prepare to make their ways home for the holidays, GP Margaret McCartney and Kavita Vedhara of Nottingham University discuss some of the challenges of fast mass covid testing and false negatives. Presented by Alex Lathbridge Produced by Alex Mansfield and Melanie Brown.

Last weekend a joint European-US satellite blasted into space to begin its mission - monitoring the oceans back here on earth. Sentinel 6 Michael Freilich is one of a long line of satellites and has a striking design – appearing like a bright gold farmyard barn with a big pitched roof. Anand Jagatia speaks to Dr Ralph Cordey at Airbus Space and Defence about the latest design iteration and the technology on-board. Oceanographer Professor Penny Holiday from the National Oceanography Centre explains how Sentinel 6’s readings will enhance understanding of sea-level rises and give more detail about the currents in our oceans. We journey back to the cosmic ‘Dark Ages’, a period of time that we know hardly anything about. Dr Emma Chapman is an astrophysicist at Imperial College London who has written a book ‘First Light: Switching on Stars at the Dawn of Time’ to throw light on this illusive chapter in the history of our universe. How close are scientists to finding the first stars? With ambitious new government targets to end the sale of petrol and diesel cars by 2030 how ready are electric cars to fill the gap? One key area many companies are trying to improve are the batteries powering electric vehicles. Peter Bruce, professor of materials science from Oxford University and chief scientist at the Faraday Institution has been working on rechargeable lithium ion energy storage since the 1990s. He speaks with Anand about the current limitations and the most recent developments in battery research and development. Presented by Anand Jagatia Produced by Melanie Brown

Earlier this month, the government rolled out a pilot in Liverpool for ‘Operation Moonshot’, their proposal to spend £100 billion pounds to regularly test the entire UK population for SARS CoV 2. Anand Jagatia speaks to screening expert Dr Angela Raffle and medical test evaluator Professor Jon Deeks from the University of Birmingham. They share their concerns about the scheme and the benefits it may bring. A year ago, BBC Inside Science helped launch the Big Compost Experiment, a citizen science project run by a team at UCL. They asked the public to get involved by providing information about the matter that’s rotting in compost piles around the UK. What do people think about biodegradable plastics and what actually happens to them – do they break down like they are supposed to? Anand finds out about the results so far .from Mark Miodownik, one of the creators of this project, We travel back in time to 66 million years ago, when a massive meteorite smacked into the Gulf of Mexico bringing the reign of the dinosaurs to a cataclysmic conclusion. It was also the beginning of a new chapter in the history of life on Earth. The impact may have caused an apocalypse of earthquakes, tsunamis, volcanic eruptions and the darkness of a nuclear winter; but it may also have created a haven for new life forms to emerge. Roland Pease has been talking to two geologists, David Kring and Tim Bralower, who have found evidence for the return of life in the crater after the carnage of the meteorite strike. Presented by Anand Jagatia Produced by Melanie Brown

Scientists this week announced hopeful results in two of the big COVID-19 vaccination trials. Trudie Lang, Professor of Global Health at the Nuffield Department of Medicine, Oxford, describes some of the methodology used, what the efficacy statistic means, and how the novel approach of inserting mRNA rather than deactivated virus parts, is so exciting. Prof Charles Cockell has been investigating how bacteria might be grown in space on lumps of asteroid to extract precious minerals, and as Kim McAllister reports, his lab is itself in orbit. And it is just a few weeks since the UK, and several other countries, signed up to a set of bilateral agreements with the US called the Artemis Accords. These are an attempt to update previous outer space treaties on how countries - and indeed companies - might mine and use resources in space, given that no-one can currently legally claim sovereignty. As Dr Thomas Cheney of the Open University and Prof Jill Stuart of the LSE describe, the Accords have been greeted in certain quarters with some discord. Presented by Marnie Chesterton Produced by Alex Mansfield Made in collaboration with The Open University.

We know that children can catch the SarsCov2 virus, even though adverse side effects are incredibly rare. But what isn't clear is how likely they are to transmit the virus? If you’re a parent, are you in danger of catching the virus, maybe brought home from school by your child? A large study, using the anonymised health experiences of around 12 million adults registered with GPs in England, has just been published that explores that question. Dr Laurie Tomlinson, of London School of Hygiene and Tropical Medicine, explains the findings. On October 30th a magnitude 7 earthquake under the Aegean Sea created devastation when it struck Turkish city of Izmir. Marnie discusses the nature of the earthquake and why this area is so seismically active with Dr Laura Gregory, a geologist at Leeds University who has studied the rocks in the region. Professor Tiziana Rossetto, an expert in earthquake engineering at UCL, talks about a recent survey and intervention she carried out with the residents of Izmir to help them prepare for earthquakes. In the last of our interviews with the authors shortlisted for the Royal Society Insight Investment Science Book Prize 2020 Adam Rutherford meets the winner, Dr Camilla Pang. At the age of eight she was diagnosed with autism spectrum disorder. Struggling to understand the world around her, she went in search of a blueprint or a manual that would help her navigate the curious world of human social customs. Nearly two decades on, Camilla has produced one herself, entitled: Explaining Humans: What Science Can Teach Us about Life, Love and Relationships. Presenter: Marnie Chesterton Editor: Deborah Cohen

Marnie Chesterton presents an update on the week's science. Behind your eyes, above your mouth but below the brain, two 3cm saliva glands have been hiding since anatomy began. So reports a new study by Matthijs Valstar and Wouter Vogel of The Netherlands Cancer Institute. They describe to Marnie how they found these hitherto unnoticed glands, and importantly how knowledge of these will help people treated for head and neck cancers to get on with their lives in the future. It may be that radiotherapies have been inadvertantly destroying the glands in the past, leading to difficulties eating and breathing. Bill Bryson is the latest in BBC Inside Science's flick through 2020's Royal Society Book Prize shortlisted authors. He talks to Adam Rutherford about his work, The Body: A Guide for Occupants, and his continuing awe at its complexity. And Roland Pease reports on evidence of a return to the Dust Bowl conditions that so devastated agriculture and livelihoods in the US mid-west during the 1930s. This time, we can see the dust storms gathering from space. But that doesn't mean that intensive agriculture, extreme weather and climate change aren't combining to do what might be a re-run of some of the disastrous issues from those years. Presented by Marnie Chesterton Produced by Alex Mansfield Produced in collaboration with The Open University.

If you contracted COVID will you then be protected from further infections and illness from SARS-CoV-2 in the future? We’re starting to hear about cases of people being infected by the novel coronavirus for a second time. A handful of these cases have been published in peer reviewed journals. Nottingham University’s Professor of Virology Jonathan Ball discusses how big the problem of reinfection might be. Is it likely to be a common event which could hamper efforts to bring the pandemic under control? In the latest in our series interviewing the shortlisted authors from this year’s Royal Society Insight Investment Science Book Prize, Susannah Cahalan talks to Adam Rutherford about her investigative journalism into the scientific mystery that is mental illness. Her book ‘The Great Pretender - The Undercover Mission that Changed our Understanding of Madness’ focuses on a fundamental experiment carried out in the 1970s by renowned Stanford University Professor of Psychology David Rosenhan. His famous study was published in Science under the title ‘Being Sane in Insane Places’ and describes using ‘pseudo-patients’ to test whether they would be spotted presenting at psychiatric institutions in the US. They weren’t! His findings proceeded to shape modern psychology and psychiatry. It has been a study that Susannah, has come to find rather mysterious, with elaborate descriptions that don’t always seem to add up. Mental illness and applied neuroscience remain tricky disciplines to navigate, but Susannah has had personal experience with her own misdiagnosis of schizophrenia when she has an autoimmune brain disease. COVID does funny things to your sense of smell: Adam got a heightened sense of smell, producer Fi totally lost her sense of smell, and Inside Science reporter, Geoff Marsh – well… his sense of smell just got weird. To find out why, Geoff called in Professors Mathew Cobb, an expert on smell at the University of Manchester, and Tim Spector from Kings College London whose symptom tracker app was instrumental in getting changes to sense of smell on the symptom list for COVID.

From the very start of the COVID pandemic, test and trace has been the mantra. But here in the UK it was started, then abandoned as the number of cases rose too high to manage. It’s now been reintroduced and we’re all being encouraged to download the ‘NHS COVID-19’ phone app which can detect whether you’ve been near an infected person using Bluetooth technology. How have other countries around the world been managing to find, test, trace, isolate and support (FTTIS) their COVID patients? And what lessons can we learn from them? Professor Michael Hopkins at the Science Policy Research Unit (SPRU), University of Sussex Business School is part of an international team of experts in science policy, social science, medicine, epidemiology and global health that has analysed and compared national testing systems in 6 countries: Spain, South Korea, South Africa, Ireland, Germany and us, in June, July and August. Michael Hopkins told Marnie Chesterton that we all have something to learn. Over the last few weeks, we’ve been stealing a glimpse into this year’s shortlisted contenders for the annual Royal Society’s Insight Investment Science Book Prize. Linda Scott is an Emeritus Professor from the University of Oxford and a consultant to the World Bank Group on gender economics. Her book, The ‘Double X Economy - The Epic Potential of Empowering Women ’ analyses the economics of gender inequality and the hidden economics which is foundational to the more recognised and acknowledged global economics, that is, the work - much of it unpaid - done by women.

Claudia Hammond looks at the neuroscience behind our sense of touch. Why does a gentle touch from a loved one make us feel good? This is a question that neuroscientists have been exploring since the late 1990's, following the discovery of a special class of nerve fibres in the skin. There seems to be a neurological system dedicated to sensing and processing the gentle stroking you might receive from a parent or lover or friend, or that a monkey might receive from another grooming it. Claudia talks to neuroscientists Victoria Abraira, Rebecca Bohme, Katerina Fotopoulou and Francis McGlone who all investigate our sense of emotional touch, and she hears from Ian Waterman who lost his sense of touch at the age of eighteen. Producer: Andrew Luck-Baker

There are few images as awe-inspiring as those of the deep cosmos. Photos of the stars, galaxies, constellations and cosmic nebulae are difficult to improve on, but a new book might have done just that, by making them stereoscopic. David Eicher, Editor-in-Chief of Astronomy Magazine teamed up with astro-photographer J. P. Metsavainio, all engineered by astrophysicist and stereoscope enthusiast Dr Brian May, and they’ve created the first ever book on nebulae in 3-D, It’s called ‘Cosmic Clouds 3-D’, and is published by The London Stereoscopic Company. Have you ever thought about how fish arrive in a new pond or lake? Birds fly, other animals walk, or crawl, but fish are somewhat restricted to watery routes, and new lakes don’t necessarily have watery routes that fish can swim down. This question has been puzzling biologists for centuries. Andy Green, professor at the Doñana Biological Station in Spain has finally come up with the answer – a small number of fish eggs can survive in the guts of birds such as ducks. The Royal Society’s Insight Investment Science Book Prize shortlist was announced last week. And as every year, Inside Science is previewing each of the books, and talking to the six authors in line for this most prestigious literary prize. This week, physicist and Radio 4 brethren Jim Al-Khalili talks to Adam about how his book The World According to Physics shines a light on the most profound insights revealed by modern physics. Presenter – Adam Rutherford Producer – Fiona Roberts Produced in partnership with The Open University

The Royal Society’s Insight Investment Science Book Prize’s shortlist has just been announced. Over the next few weeks, Marnie and Adam will be chatting to the six authors in line for the prestigious prize. They’ll be getting a guided tour of ‘The Body – a Guide for Occupants’ with Bill Bryson; Discussing ‘Life According to Physics’ with Jim Al Khalili; Explaining Humans: Discovering ‘What Science Can Teach Us about Life, Love and Relationships’ with Camilla Pang; Linda Scott will be exploring ‘The Epic Potential of Empowering Women’ in her book ‘The Double X Economy’ and Susannah Cahalan will grapple with the definition of mental illness and what counts as insanity in ‘The Great Pretender: The Undercover Mission That Changed Our Understanding of Madness’. This week Gaia Vince discusses her shortlisted book Transcendence - How Humans Evolved through Fire, Language, Beauty, and Time. Last week the non-COVID news was all about how we’d failed yet again to halt the rate of biodiversity loss. The 2020 Living Planet Report showed that across the globe, the populations of mammals, birds, fish, amphibians and reptiles have declined on average by 68% since 1970. These declines, and the less well-documented loss of abundance of many plants and invertebrates, mean that our ecosystems are less diverse, less resilient and less able to provide the ecosystem services that we rely upon. Add to this that The Convention on Biological Diversity’s Fifth Global Biodiversity Outlook reports that we have failed to meet in full any of the 20 ‘Aichi Targets’ adopted by the world’s governments a decade ago. We haven’t reduced the loss of biodiversity, addressed the pressures, adequately tackled the underlying drivers or effectively facilitated the enabling conditions. We are not currently on track to meet the Convention on Biological Diversity (CBD)’s Vision of a world living in harmony with nature by 2050. If all this is making you feel depressed and despondent, be reassured that it's is not all doom and gloom, as there are still plenty of reasons for hope and optimism, according to Dr. Stuart Butchart, chief scientist at Birdlife International. The Science Museum group look after over 7.3 million items. As with most museums, the collection you see on display when you visit is only the tip of the iceberg of the entire collection. Up until now, many of the remainder (300,000 objects) has been stored in Blythe House in London. But now the collection is being moved to a purpose-built warehouse in Wiltshire. The move is a perfect opportunity for curators to see what’s there, re-catalogue long hidden gems and to conserve and care for their treasures. But during the process they have discovered a number of unidentified items that have been mislabelled or not catalogued properly in the past and some of them are just so mysterious, or esoteric, that the Science Museum needs the aid of the public to help identify them, and their uses. This week, Jessica Bradford, the keeper of collection engagement at the Science Museum is asking Inside Science listeners if they recognise, or can shed light on the possible use of the brass object with a folding fan at the end’ in the picture above.

As it starts to get colder and we crank up the central heating in our homes, what will the effect be on the SARs-CoV-2 virus? As a respiratory virus like the common cold and influenza, will the coronavirus have a distinct season and will the incidence of COVID get worse in the winter? A pre-print study of over 7000 hospitalised patients across Europe and China during the early days of the pandemic plotted severity of the disease with outside temperature. In European countries as we came out of winter, into spring and then summer, Professor Gordan Lauc, lead researcher on the study, found that the severity decreased as it got warmer outside. He took outside temperature as a proxy for indoor humidity (as it gets colder, we turn on our heating, stay indoors more and the humidity in our homes, and especially our bedrooms drops). He explains to Marnie Chesterton that the subsequent drying out of our mucosal membranes in our noses and throats could be the reason we might expect things to get worse over the winter. We learn a lot about what our ancestors got up to by visualising a scene. Take Stonehenge for example, years of detective work has ascertained that 4,000 years ago, Stonehenge was made up of an outer circle of 30 standing stones called ‘sarsens’, which surrounded five huge stone arches in a horseshoe shape. There were also two circles made of smaller ‘bluestones’ – one inside the outer circle and one inside the horseshoe. But what did it sound like if you were in the middle of all these stones in prehistoric times? Last year, acoustic engineer at the University of Salford, Trevor Cox, and his team built and measured a 1:12 acoustic scale model of Stonehenge to find out. They've now completed the full analysis of those first measurements and Trevor caught up with Adam Rutherford to find out whether knowing the acoustics of a monument can tell us anything about how it might have been used. If you own a dog and like to calculate the equivalent human age of your pup, you might think that every year of your dog’s age equals 7 years in humans. So a one year old hound is 7 years old. Not so! As Geoff Marsh investigates - it’s much more complicated than that. Of course it is! Presenter – Marnie Chesterton Producer – Fiona Roberts

Vaccination has eradicated smallpox, a disease that decimated populations through the 20th century. Polio is almost gone too, and measles is no longer the pervasive childhood threat it once was. It’s clear that vaccination is our best tool to halt the threat of SARS CoV 2, and allow the return to a less restricted way of life. But it takes time to develop and test vaccines although the technologies used to create them have moved on significantly over the last few decades. Professor Jonathan Ball, a virologist at Nottingham University, talks Adam Rutherford through the several types of vaccine that are being explored in the effort to stop the coronavirus pandemic, and how they work. These include live attenuated virus vaccines that are genetically modified to appear to be SARS CoV 2 to the immune system, and RNA subunit vaccines that trick the body into recognising the virus. He discusses the way different vaccines work against disease, and how they trigger different types of immune response. Before a vaccine is approved for general use it has to pass through three trial phases, and Jonathan discusses the vaccines that are already going through phase 2 and 3 in the UK. If and when a vaccine gets approved, it needs to be produced to exacting standards and in quantities great enough to immunise the whole population. The UK Vaccine Manufacturing Taskforce was set up in May to coordinate the effort to make a vaccine. Steve Bagshaw, part of the Taskforce, explains that some vaccines have already been produced around the UK, prior to clinical approval in an effort to ensure that any approved vaccine is ready to be distributed as fast as possible to those at risk. This is unprecedented, and means the pathway to vaccine distribution could be faster than any that have gone before. Presented by Adam Rutherford Produced by Fiona Roberts and Rory Galloway

Skulls give researchers a great deal of insight into how an animal might have evolved, and skulls can be sensibly compared between species and groups of animals. The 10,000 species of bird around the world are what’s left of an even more diverse group, the dinosaurs. But research on their skulls has revealed that despite the birds’ exceptional diversity, they evolve far more slowly than their dinosaur relatives ever did. This is one of the findings of a huge skull mapping project at the Natural History Museum led by Anjali Goswami. Marnie Chesterton delights Adam Rutherford with what she has recently learned about the single-celled fungus that is yeast. She recently visited the National Collection of Yeast Cultures in Norwich, which stores hundreds of thousands of strains of yeast. She discovered that yeast is not only responsible for the production and subtle flavours of bread, yeast and chocolate, but also that some species of yeast can actually clean carbon dioxide from the air and can be used to feed livestock. The Science Museum Group looks after over 7.3 million items. As with most museums, the objects you see on display when you visit is only the tip of the iceberg of the entire collection.

Over the next couple of weeks almost all children in the UK will be back to school. But the pandemic hasn’t ended, and we are far from having a complete understanding of how this virus works, including how it is transmitted and how it affects younger people. Pretty much everyone is in agreement that kids need to be back at school, as the costs of not being physically in classrooms are great - for the education of kids, for their mental health, and for the finances of parents needing to work. But what does the science say about the risks for schools reopening? Will we see a rise in infections in younger people, and hot-spots for the wider community? Adam Rutherford discusses these issues with Paul Hunter, Professor of Medicine at Norwich Medical School, and he finds out from Professor Tim Spector if his Kings College COVID symptom tracker app can shed any more light on whether children display the same COVID symptoms as adults, or could we be missing infections in the young? Marnie Chesterton eavesdrops on an aquatic autopsy. We pollute the oceans with noise that has some serious effects on marine life. Remotely via video link up, Marnie witnesses a complex autopsy on the inner ear of a dolphin. She discovers how accurately the death of the sensory hair cells in a cetacean’s ear records the time of damage. Presenter – Adam Rutherford Producer – Fiona Roberts

Red clay bricks are among the most ubiquitous building materials worldwide. Julio D'Arcy, a chemist at Washington University in St. Louis, Missouri, describes to Adam Rutherford how he and his team have turned ordinary house bricks into energy storage units that can power home electronic devices – thanks to the red iron oxide (rust) pigment and a conductive plastic nano-material infused into the bricks These new ‘smart bricks’ can be charged to hold electricity a bit like a battery. As the pandemic continues, we continue to try to find ways to manage it, treat the disease, detect it and cure it. As necessity is the mother of invention, we're currently witnessing some of the most intense periods of scientific innovation in the 21st century. And there have been some incredible discoveries, innovations and inventions in just the last 6 months. The Royal Academy of Engineering announced a special round of awards this week, to recognise the heroics of engineers, designers and scientists to help tackle this pandemic. Professor Raffaella Oconé is Chair of the Awards Committee at the Royal Academy of Engineering, and she told Adam about the range of much needed inventions to tackle COVID19. The current mantra of 'test, track and trace has so far had limited success in the UK. In part because of the difficulty of testing enough people, tracking their movements and tracing the spread of the virus. By the time someone is displaying symptoms and then being one of the few people to then get a test, they may have spread the virus to many people. But scientists across the UK and abroad are beginning to realise that maybe there might be a cheaper alternative, that gives even earlier warning of a spike in infection - by detecting the virus in sewage.

COVID19 is a chilling reminder of how pathogens from animals can jump into humans. But it’s not the first time. SARS, Ebola, West Nile virus and bubonic plague are all serious infectious diseases that sat in a host species before crossing to us. But what causes this to happen? Individual case studies suggest that we are partly to blame in the way we use the land, either through urbanisation or agriculture. But how widespread is this, and do our global patterns of land use systematically put us at risk? Adam talks to environmental biologist David Redding from the Zoological Society of London, and his team, whose new study suggests they do. Jessica Bradford, the Keeper of Collection Engagement at the Science Museum, asks for your help with another mystery object that they’ve uncovered during their recent collection move. Roland Pease reports on the chain of interconnected faults which has stimulated Los Angeles' preparation for “the big one”, after southern California was hit by one of the biggest earthquakes in the area for decades. Adam also asks Neil Gemmell from the University of Otago in New Zealand about the weird and wonderful Tuatara, whose colossal genome he’s just sequenced. Presenter: Adam Rutherford Producer: Beth Eastwood

Adam reveals new research which overturns received wisdom about how sperm swim. More than three centuries after Antonie van Leeuwenhoek peered down his early microscope to observe human sperm or ‘animalcules’ swimming with a ‘snakelike movement, like eels in water’, high-tech observations now reveal that this was, in fact, an optical illusion. Hermes Gadelha from Bristol University used 3D microscopy, a high-speed camera and mathematics, to reconstruct the true movement of the sperm tail. Much to his amazement, sperm have a highly sophisticated way of rolling as they swim. They do this to counter the numerous irregularities in their morphology which would otherwise send them swimming in circles. In doing so, they are able to propel themselves forwards. This highly complex set of movements, seen in 3D, is obscured in 2D when sperm appear to use a symmetrical eel-like motion to swim. Also on the programme, Adam gets an update from Mark Miodownik on the Big Compost Experiment, the citizen science project that wants to know what you compost, how you do it and, most importantly, how quickly the stuff breaks down. Mark reveals how confused participants are, about what they can compost, and explains why items marked ‘compostable’ or biodegradable’ won’t compost at home. Staying with soil, healthy soil is being lost at an alarming rate due to intensive agricultural practices. In England and Wales, a recent survey found that nearly forty percent of arable soils were degraded. Inside Science reporter Madeleine Findlay visits Andrew Neil from Rothamsted Research who has devised a new way of thinking about soil. They’ve solved the mystery of why adding carbon through organic material, like compost, improves soil health. PRODUCERS: Beth Eastwood & Fiona Roberts

We’ll be showcasing items over the next weeks and months, but this week, Jessica Bradford, the keeper of collection engagement at the Science Museum is asking Inside Science listeners if they recognise, or can shed light on the possible use of the ‘scoop’ in the picture above. Send suggestions to Email: [email protected] or [email protected] People install and use home security cameras for peace of mind. But the very behaviour of the commonly used IP home security cameras (internet-connected security cameras) could be giving away important information about your household to potential burglars. Gareth Tyson, at Queen Mary University London, has been working with researchers in China to explore how we use these home security camera systems and to look for flaws in the security of security cameras. Last Saturday, 25th July, was a hundred years since the birth of chemist Rosalind Franklin. She is perhaps most famous for her work using X-ray crystallography which helped lead to the discovery of the double helix structure of DNA, a contribution for which she was not credited at the time. But there’s so much more to the scientific story of her life than just being the wronged woman in the DNA story, who died tragically young at the age of just 37. She pioneered work in the coal industry and on the structure of viruses, including the polio virus. And Franklin’s work has resonance today, in this era of COVID-19. Baroness Nicola Blackwood, chair of Genomics England thinks Rosalind Franklin’s legacy is something we should be very proud of today.

A pre-print is a way for scientists to get their work out quickly for other scientists to comment on and debate. But pre-prints are not peer reviewed; they have not undergone the scrutiny of reviewers and journal editors. They're generally seen as a good thing, but are just a step on the way for science to be verified and published. But it's important to note that the science can be wrong or sloppy in pre-prints, so they have never really been part of the process by which science is disseminated to the general public. That is, until the COVID pandemic. The speed at which the science can be shared has led to pre-prints becoming more and more scrutinised by journalists and used to inform the public about this terrible disease. Fiona Fox, CEO of the Science Media Centre, which is an independent press office for the scientific community, discusses the potential pitfalls of using pre-prints with Adam Rutherford and with Dr Jonathan Read from Lancaster University, who himself got caught up in a pre-print firestorm at the start of the pandemic. The UK has the 12th highest road density in the world, but very little is known about the impact of roads on our wildlife. Now conservation scientists are starting to look at their effects on our bird populations. They call it ‘road exposure’ because they can’t directly measure the impact of road noise, but the noise pollution aspect is very much to the fore. Cambridge University's Sophia Cook has found that roads have a mostly negative effect on most birds in Great Britain. And with that negative effect being stronger in rarer birds this could be adding to the 'simplification' of bird populations and a reduction in biodiversity.

Science is all about self-reflection. Scientists constantly check themselves, share their work, and check each other’s data. But how robust is the science upon which civilisation is built, the science which has mapped genomes, cured diseases, split atoms and sent people to the moon? Adam talks to Stuart Ritchie, a psychologist from Kings College London, about his new book Science Fictions which explores everything from biases and human fallibility, to outright fraud. He also talks to microbiologist turned image sleuth, Elisabeth Bik, whose work is revealing that manipulated images appear in scientific papers shockingly often. Now we are several months into the COVID pandemic, scientists are beginning to share their first insights into whether people retain immunity to SARS-CoV-2 after they've had the disease COVID-19. At Kings College London, Senior Lecturer in Infectious Diseases, Katie Doores and her team tracked the antibody levels over the first months after infection with COVID-19. Their first preprint findings suggest a worrying pattern – antibodies against the virus begin to wane within months of being infected. However it is too early to say if and when a person who’s had COVID-19 could be vulnerable to reinfection. Early findings from Marcus Buggert, at the Karolinska Institute in Sweden, suggest that another part of the immune system, the memory T-cells, are active in those who have had the disease, even if they lack antibodies against the virus.

Is the UK losing its way when it comes to satellite navigation? There's GPS from the US, but other countries and regions, including Russia, China, India and Japan, either have, or are building, satellite navigation systems of their own. The EU has Galileo, but with Brexit, Britain is no longer involved. The Government has announced that it’s just acquired a satellite technology company called OneWeb. It’s primary role is enhanced broadband, but there’s talk of adding in a navigation function to the constellation of satellites. But how feasible will that be? In an era of cyber-crime, misinformation, disinformation, state-sponsored attacks on rival countries’ infrastructure, government-imposed internet shutdowns in places like Eritrea and Kashmir, the World Wide Web is an increasingly dark and troubled place. Making sense of how the internet has changed from the democratic, sharing, open platform it was designed to be, and predicting what’s next, are the web scientists. Professor Dame Wendy Hall, Regius Professor of Computer Science at the University of Southampton, and a co-founder of the whole field of web science, is hosting an online, annual conference this week. The theme this year is 'Making the web human-centric'. Communal burial sites tend to suggest an egalitarian society, where everyone is considered equal. And this is what we expected the Neolithic societies that spread across Europe with the birth of agriculture around 6000 years ago would be. But DNA evidence from a single human, NG10, buried in 3200 B.C.E in the vast tomb of Newgrange, 25 miles north of Dublin, in Ireland, shows very strong inbreeding. Couple this with the fact the body was buried and not cremated and placed in a highly adorned chamber. Does this indicate an elite ruling class where marrying one’s close kin was the order of the day? Dr. Lara Cassidy, palaeogeneticist at Trinity College Dublin, decoded NG10’s DNA and she tells Adam Rutherford the story. Presenter - Gareth Mitchell Producers - Fiona Roberts and Beth Eastwood

As we’re beginning to understand more about SARS-CoV-2, the virus that causes COVID-19, we’re hopefully starting to get some clues on how to deal with the next viral pandemics, and even look at ways of stopping them from happening. To do this, we have to go back to where the virus jumped from its animal host into humans. Like this current coronavirus, many of the pandemic viruses (SARS, MERS HIV, Ebola…to name a few) are zoonotic diseases. They start in wild animals and evolve to jump to humans (sometimes via another animal species). It’s not the animal’s fault. It’s evolution. But has our tangled, often exploitative relationship with wild animals made it harder to stop future pandemics? A paper just published asks these questions and tries to figure out how to prevent future zoonotic epidemics. Dr. Silviu Petrovan (Researcher in the Department of Zoology in Cambridge) and Associate Professor Alice Hughes (Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences) highlight some of the 161 possible actions we should be taking to protect ourselves from the next pandemic. The current pandemic may have curtailed a lot of holiday plans but we are still more global than ever before. Food is coming to the UK from all over the world. With movement comes the opportunity for unwelcome hitchhikers to tag along. A new study, published in Biological Reviews, by a team of researchers from 13 different countries warns that alien species invasions are on the rise. Professor Tim Blackburn from University College London talks to Marnie about this increasing threat. Also on the programme, inspired by a listener question, Marnie asks whether there's any truth behind the idea that susceptibility to COVID-19 could be linked to blood type. Associate Professor of Venom Pharmacology at Reading University, Dr Sakthivel Vaiyapuri, explains what the science says so far. Producers: Fiona Roberts & Beth Eastwood

Adam Rutherford is back to celebrate the 20th anniversary of one of the most ambitious and revolutionary scientific endeavours of all time - the Human Genome Project. Its scope and scale was breath-taking, set up to read every one of the 3 billion nucleotides, or letters of genetic information, contained within the DNA in every cell of the human body. It took seven years, hundreds of scientists, cost almost $3 billion and, amazingly, came in under budget and on time. Adam reflects back on that momentous time with Ewan Birney, Director of the European Bio-informatics Institute, part of the European Molecular Biology Laboratory. Twenty years ago, he was a PhD student working on the project, in the months leading up to the first draft. The Human Genome Project underpins many branches of science, from human evolution and synthetic biology to forensic genetics and ancestry testing. But a key motivation for the project was to alleviate human suffering. While the ‘cures’, hyped by the media back in 2000, were not realistic our understanding of disease has been revolutionised. Adam talks to Cancer Research UK Scientist, Dr Serena Nik-Zainal, from Cambridge University, who explains why the sequencing of the human genome has been so crucial to the diagnosis and treatment of breast cancer. The Human Genome Project is also playing a crucial role in the COVID-19 pandemic. Dr Kenneth Baillie has been treating critically ill patients at Edinburgh’s Royal Infirmary since the pandemic started. As the Lead on GenOMICC, a global collaboration on genetics and critical illness, he has joined forces with Genomics England and the NHS, to pinpoint genetic signals in these patients to help identify the best treatments. Producers: Beth Eastwood & Fiona Roberts

Throughout the pandemic, we've seen an explosion in information about the science of the virus, SARS-CoV-2, and the disease it causes, COVID-19. An article online, or a text forwarded, could be true and sounds about right, but how do you know that it's accurate? When scrolling through your social feed, how do you decipher fact from fiction? A new report, by Kings College London and Ipsos MORI, reveals that those of us who get our news from social media are more likely to believe misinformation about the pandemic. Marnie talks to Jack Goodman of the Anti-Disinformation Unit at BBC Online, a new team set up to tackle the problem. She finds out how science fact turns to science fiction online, and what the team is doing to try to counter this. Now that wearing face masks are now mandatory in a number of situations, a lot of us are making our own. BBC Inside Science listeners sent in lots of ideas about the design, maintenance and durability of face masks, and other ways to protect against spreading the coronavirus. We asked Professor of Materials & Society at UCL Mark Miodownik in to comment. In February this year, the European Space Agency’s Solar Orbiter, SolO, successfully launched, escaping this planet before most of us went into lock-down. Professor Lucie Green from the Mullard Space Science Lab at University College London, is a solar scientist and part of the team that will be using a telescope to take images of the Sun in extreme ultraviolet light. The orbiter is now in it’s ‘Cruise Phase’ which means most of its instruments have now been tested and calibrated, but aren’t yet up and running. One instrument that has been operational since just after launch is the magnetometer, which will collect data on the Sun’s complex and dynamic magnetic field.

As the UK gradually begins to ease out of lockdown, Marnie explores how engineers are hoping to reduce the spread of Covid-19. We’ve learned how infected people exhale droplets and aerosols, containing the virus, and how we can then either inhale them, or transfer them to our faces by touching contaminated surfaces. Many shops already have screens and physical barriers, while schools and offices are re-configuring desks and walkways. What role does the environment play in our overall risk of becoming infected and what can we do about it? This is the focus of the SAGE Environmental Working Group. Marnie talks to its Chair, Catherine Noakes, Professor of Environmental Engineering for Buildings at Leeds University. Minimising the risks that contaminated surfaces pose is a key challenge that engineers are now trying to address. Marnie asks Birmingham University Research Scientist, Felicity de Cogan, about the surface she created which kills bacteria in seconds. She's now re-purposing the technology to kill the virus that causes Covid-19. If her laboratory studies prove that it kills the virus as quickly, as she hopes, the technology could be used to create antiviral PPE that can be re-used rather than thrown away. Epidemiology has been thrust into the spotlight in recent months, helping us track the viral threat facing all of us. But companion animal epidemiology - which studies disease in pet populations - is a much younger field. It’s one that’s starting to search for the answers to another puppy-related conundrum that’s been puzzling BBC Inside Science reporter Geoff Marsh - should he get puppy Kevin castrated? Neutering has become a cultural norm in the UK. But the health risks to neutered male dogs include cancers and joint disorders in some breeds. The operation and anaesthetic carries some risk as does the age of the dog when the operation is carried out. The risk of dog populations exploding with hundreds of un-neutered dogs is low, because most owners control their dogs to such a degree the chance of unplanned mating doesn't come up. But neutering can help with some behavioural problems in pet dogs. So what is the answer? Will Kevin remain intact? Presenter - Marnie Chesterton Producers - Beth Eastwood and Fiona Roberts

As the lockdown eases and some children, in preschool and primary years, start heading back to school, what impact will this have on the pandemic, how will we know and is there anything we can do about it? Marnie Chesterton talks to Professor of Mathematical Biology at Cambridge University, Julia Gog, who co-chaired the group that advised the government on the impact of easing school closures. She explains why the limited opening of schools provides a golden opportunity to learn about its impact on the pandemic, and inform what happens in September when the new school year begins. Marnie also talks to Tim Spector, Professor of Genetic Epidemiology at King’s College London, to find out what parents can do to help control the spread of the virus in their communities. He runs the COVID Symptom Study, a huge citizen science project that’s pinpointing the symptoms most closely associated with Covid-19. Millions of British adults have downloaded the app, to take part in the study, logging how they feel each day and adding symptoms when they feel unwell. The breakthrough that losing your sense of smell, or anosmia, is a common symptom in Covid-19, arose from this app. While children with Covid-19 tend to have mild or no symptoms, Tim Spector believes that some cases are being missed because many of the symptoms we’re told to look out for in adults, such as fever, are transient or absent in children. Tim explains which symptoms parents should look out for in children, including anosmia and a range of rashes such as ‘covid toe’. If parents log their children’s symptoms each day, the hope is he’ll have enough data to further refine the symptoms most closely associated with Covid-19 in children. Parents will then be better placed to spot them, if they occur, and keep their children at home. You might be forgiven for thinking that Ordnance Survey (OS), the national mapping agency for Great Britain, would be having a quiet time during the lockdown. But its online OS Map apps have seen a 300% increase in use, with users not only checking out new places and walks in their local area, but using the virtual maps to plan and imagine themselves on walks in more remote and far flung parts of Great Britain. But Ordnance Survey is so much more than just leisure maps. It runs the Master Map of Great Britain, a massive, interactive, geospatial database which can be interrogated by anyone in the public sector with questions on geography, planning, logistics, addresses and more. The list is long. And during the coronavirus pandemic, the Mapping for Emergencies service has been busy helping the NHS find places for blood testing facilities and PPE storage; working out which walkways are wide enough to allow social distancing, working out where the nearest pharmacies to vulnerable people are and much more.

Inside Science this week is all about our information - the stuff we volunteer and the traces our everyday movements leave behind. With the launch of NHS Test and Trace across England, if you start to feel unwell with suspected Covid-19 and call a new NHS hotline 119, you’ll be tested for the virus. Your close contacts will be traced and, if you test positive, you'll be asked to self-isolate for 7 days, and your contacts asked to quarantine for 14 days. The route to those close contacts is currently through manual tracing - you have to give the details of everyone with whom you’ve been in close contact. But in the coming weeks, the plan is to integrate the NHSX app, currently being trialled on the Isle of Wight. This will pick up close contacts with people you don't know, on public transport, for example, provided they also have the app. It’s a new way to fight a pandemic, but the pioneers here are the residents of the English town of Haslemere in Surrey who, back in 2017, were tackling a terrifyingly contagious and, thankfully, hypothetical virus spread by ‘patient zero’ Hannah Fry. Created for the BBC4 documentary: Contagion, it was an experiment to see how we could fight the next pandemic. The BBC built an app, which residents downloaded and, crucially, it created a data-set. Evolutionary Biologist Dr Lewis Spurgin, from University of East Anglia, has used this data-set to explore the impact that different control strategies could have on the spread of the virus that causes Covid-19. In a different case of tracking and tracing, involving some policing by members of the public and journalists, Dominic Cummings’ comings and goings have consumed the nation this week. Just how much are our everyday movements being clocked, monitored and recorded? What traces do our phones, cars and even our faces leave behind? And who gets to see this information? Marnie talks to researcher and broadcaster Stephanie Hare, author of the forthcoming book Technology Ethics. Presenter: Marnie Chesterton Producers: Beth Eastwood & Fiona Roberts

In response to listeners who have expressed coronavirus fatigue in recent weeks, Marnie Chesterton brings us up to date on some of the best and brightest breaking science we might have missed, with BBC’s Non-Covid-19 Science Correspondent Jonathan Amos. Inching back to pandemic news, Marnie investigates the fallout of the lockdown from a climate perspective. In many countries, citizens have been asked to stay at home and not to travel unless it’s strictly necessary. As a result, the hubbub of normal life has slowed to a trickle. What impact has this had on levels of carbon dioxide in the atmosphere? Corinne Le Quéré, the Royal Society Professor of Climate Change Science at the University of East Anglia, explains just how dramatically these emissions have been affected around the world. And the chances that intelligent life exists on other planets. David Kipping, Assistant Professor of Astronomy at Columbia University in the US, has calculated the odds of both life and intelligent life existing if he were to re-run earth’s history. Presenter - Marnie Chesterton Producer - Beth Eastwood

R seems to have found its way into the newspapers and on Radio 4 as if it’s a word, or a letter, that we should all be familiar with and understand. As part of the government’s briefing on Sunday, it appeared in a pseudo-equation, the infographic - 'COVID alert level = R + number of infections' - the Government called R the 'Rate of Infection', but it is commonly known as the 'Reproduction Number'. So what exactly is R, and what does it do? Mathematical Biologist, Kit Yates, from the University of Bath, clears up the confusion, and explains how R was first calculated for covid-19. And one of the scientists tracking R in the UK is Petra Klepac, who is Assistant Professor in Infectious Disease Modelling at the London School of Hygiene and Tropical Medicine. She explains how crucial R is in tracking the pandemic and how it’s now being used to shape the way we get out of lockdown. There are so many variables about who will survive Covid-19 and who, unfortunately, will not. Many people will only experience mild symptoms, but a minority will have a severe or even life-threatening response. Whilst some of the difference can be explained by age, or underlying health conditions, the reasons why men and some ethnic minorities and a number of apparently fit younger people become so ill, is one of the great puzzles of this pandemic. Some of the uncertainly is down to environmental effects. But a lot of the variability could be down to our genomes. To try and find out, this week Genomics England announced funding for a study - The GenOMICC - COVID Genomics UK (CoG-UK) Partnership for Severely Ill Patients to sequence the whole genomes of 20,000 severely ill and 15,000 asymptomatic or very mild patients. Led by Genomics England, these genomes will be compared with those held in the 100,000 Genomes Project dataset. The coronavirus pandemic is really highlighting the need for fast, accurate ways to analyse data on a global and national scale. Be that data on the number of people dying or track and trace data from various apps. But do we realise how much data we leave about ourselves online even in normal times? This is something Professors Tobias Preis and Suzy Moat in the Data Science Lab, at the Warwick Business School get very excited about. They use rapid analysis of big data to try and understand our behaviour as a way to rapidly inform economists and policy makers on how the world works. They have been looking at alternative data sources to give us quicker estimates of what’s happening in the world – travel patterns, economic indicators, how many people have a given disease. This is going to become invaluable both during and in the aftermath of the pandemic, when understanding the economic fallout will be key to helping the economy recover. Take their latest work – where they’re gathering much quicker estimates on the contributions of air travel to the UK’s GDP. Presenter – Marnie Chesterton Producers – Fiona Roberts and Beth Eastwood

Advice about whether the public should wear face masks, to protect against infection by the coronavirus, differs around the world. In Europe, policy recommendations are mostly geared towards homemade masks. As this country waits to find out how we’ll venture out of lock down, should we be wearing face masks out in public too? The government’s mantra throughout the pandemic has been “follow the science” but on this issue there is ongoing debate, with strongly held and differing views. The Royal Society’s DELVE Initiative (Data Evaluation and Learning for Viral Epidemics) put out a report this week to try to bring some clarity to the issue. Marnie Chesterton asks Professor of Primary Care Health Sciences at Oxford University, Trisha Greenhalgh, and microbiologist and Professor of Environmental Healthcare at the University of Southampton, William Keevil, why there is so little science to inform the policy-makers. If the government recommends that we all wear cloth masks, we'll be wearing them for the common good - they’re better at stopping the wearer from spreading the virus than protecting him or her from catching it. Choosing one that fits, made from the right material, and keeping it clean is also crucial. If you’re not really up to making your own mask, Professor Mark Miadownik at UCL’s Institute of Making warns against the single-use surgical masks, now a common addition to the litter scene and a bane to the environment. As the SARS-CoV-2 virus that causes COVID-19 continues to spread at an alarming rate in the United States, with well over a million confirmed cases and over 70,000 deaths, attention in the White House has been turning to suggestions that the virus originated in the Institute of Virology Laboratory in Wuhan, China and not in the wild where bats are the ultimate suspected source. For years, a group there led by “bat woman” Jungli Shi, have been collecting virus samples and studying them to see if they could infect us humans. This is standard virology, trying to understand where the next pandemic viral threat might come from. But conspiracy theorists have been suggesting that there’s more going on, such as deliberate genetic manipulation of the viruses, weaponising them, or just unsafe management. These ideas have been taken up by President Trump and his team. BBC Inside Science reporter Roland Pease asks the experts what they think. Is there any place for this sort of politics in the pandemic? Presenter - Marnie Chesterton Producers - Fiona Roberts and Beth Eastwood

This week, the Government’s target to be testing 100,000 a day for COVID-19 looks like it won’t be met. But we’ve heard about many people who experienced the virus mildly, or who’ve tested positive with no symptoms at all. If you really want to know who has had the virus, the only way to tell for certain is with an antibody, or serology, test. Describing how they work is Professor of Virology at Nottingham University, Jonathan Ball. Eleanor Riley, Professor of Immunology and Infectious Disease at Edinburgh University, explains why its so important to get the specificity and sensitivity of these tests right, and reveals what they can and can't tell us about individual and population-wide exposure to the virus. We like citizen science on BBC Inside Science, it’s an opportunity for anyone and everyone to try their hand at some scientific projects, learn about the scientific process and help researchers crunch through masses of data. Professor Chris Lintott co-founded Zooniverse, the biggest citizen science platform over a decade ago. He’s a regular on the programme telling us about the latest Muon-hunting, Penguin-counting, galaxy-searching opportunities they offer. But they’re not the only ones, Butterfly Conservation want you to help them track the timing of butterfly emergence in the UK and Fold.it are asking people to play their protein folding online game to help them find a possible cure for Covid-19. But back in the 1930’s BBC radio producer Mary Adams was running a series called ‘Science in the Making’, where listeners were invited to participate in, what would now be called ‘citizen science’ experiments. With topics as diverse as charting the timing of blackbird egg laying and deciphering the meaning of dreams, a scientist would explain their hypothesis and ask the audience for help. Allan Jones, a senior lecturer in computing and communications from the Open University has been digging into the BBC’s earliest public science experiments, and the woman who decided to broadcast them.

Every death is a tragedy for grief-stricken families, but every set of statistics is an opportunity to understand the virus and the disease Covid-19 a bit more. In fact gathering these data, quickly and accurately, is a priority at the moment, up there with developing a vaccine and rolling out widespread testing. Gareth Mitchell discusses, with, David Spiegelhalter, who is the Winton Professor of the Public Understanding of Risk in the Statistical Laboratory at the University of Cambridge, why it’s so hard to measure coronavirus fatalities. The Covid-19 pandemic is unprecedented in modern times. There will no doubt be years of debating over who managed the outbreak the best, which tools and actions were implemented at the right time and in the right way. One small, but important part of dealing with the viral outbreak is contact tracing – discovering who is infected and who they might have come into contact with. This has to be done quickly, so the people an infected person had contact with, can be found and informed to isolate, before they themselves spread the virus further. Some countries used this early on in the pandemic (Singapore and South Korea, have successfully used it to contain their outbreaks, while Germany, which has a far lower case and death rate than the UK, has also worked hard on contact tracing.) Others are hoping to implement contact tracing as a means of easing social distancing or coming out of lockdown. To do this public health agencies will have to start aggressively contact tracing and at a much higher level than they were a few months ago. The UK started using contact tracing then stopped, they are now looking to restart it. A plausible way of doing this is to make use of the fact that a lot of people carry a mobile phone, so apps that can help are being developed and used. There are biological factors that need to be taken into account (reliable, accessible testing in the first place) but also logistical, practical and security issues… who are we giving our data to? And what are they doing with it? Could it be used to restrict my freedom in ways other than just managing the spread of the virus? Timandra Harkness author of Big Data, Does Size Matter? and Fellow of the Royal Statistical Society, and a member of their working group on Data Ethics helps answer these questions. Finally, a small bit of good that’s come out of another dark time in our recent history. Atomic bomb tests during the Cold War. The nuclear fallout, doubled the amount of an isotope called carbon-14 in the atmosphere. And that has turned out to be very useful for scientists working on a crucial conservation effort – to age and safeguard the world’s largest fish - the Whale Shark. Presenter - Gareth Mitchell Producer - Fiona Roberts

While the world is dealing with the coronavirus outbreak, those who are concerned about the environment are saying that an arguably bigger crisis is being side-lined. Climate change, or climate breakdown, is still happening. Just like the Covid-19 pandemic, it will be the poorest people in the poorest countries that pay the highest price for the breakdown in our climate. But can we learn something from the current lockdown that can be applied to climate change? Can it provide the impetus for us to do things differently. Writer and environmentalist George Monbiot thinks so. He recently wrote that coronavirus is ‘a wake-up call for a complacent civilisation’, and he discusses with Marnie Chesterton whether there is some hope that can be taken from the current crisis. Last year, it was announced that a new coal mine in Cumbria was given backing in parliament. The Woodhouse colliery would be Britain’s first new deep coal mine in 30 years, bringing much needed jobs to the community. The colliery, along the coast from Whitehaven, is planned to be producing coking coal for the steel industry. Cumbria County Council claimed the mine, which aims to process 2.5m tonnes of coking coal a year, would be carbon neutral, as locally produced coal, negates the need to ship it in from as far afield as the US, Canada, Russia and Colombia. It’s perhaps unsurprising that climate campaigners think this is a huge step back and that the mine is unnecessary and incompatible with UK climate ambitions and that it will hold back the development of low-carbon steelmaking. BBC Inside Science sent reporter Geoff Marsh to explore the story that highlights the difficulties of balancing carbon costs and accounting, with employment and self-sufficiency. Presenter - Marnie Chesterton Producer - Fiona Roberts

You can’t build up a picture of Covid-19’s spread throughout the UK without testing those who might have it and those who might have already had it. Britain currently is only testing people who are hospitalised, some healthcare workers and a handful of exceptions. The upshot is that we don't have reliable numbers on how many people in the community have, or have had, Covid-19. Even self-reporting doesn’t pick up those who carry the virus, but do not show any symptoms. Professor Mike Bonsall is part of a team at Oxford University running a new project that seeks to change that. They want to estimate how common the coronavirus causing disease is in the UK, using a new diagnostic tool called nanopore sequencing. If you want to take part, have not had any symptoms and live in the Oxford area - https://covidstudy.zoo.ox.ac.uk/ You probably think you know your body like the back of your hand, but given that it’s made up of an average of about 37 trillion cells, some sort of guide book might be helpful. This is what the Human Cell Atlas, an international project, is doing. By providing a map of human cell types, aims to help researchers fight diseases, from cancer to covid19. Although every cell in our bodies has the same genetic code – the same DNA; the differences between, for example, muscles cells, brain cells, and fat cells – come down to which bits of the DNA each cell uses - which genes are switched on and off. This gives cell types their different characteristics. The Atlas not only helps scientists understand the precise nature of each cell type but also how they interact with other cells in the body. There are a lot of myths surrounding the source of the rose-necked parakeets in south east England. The introduction of these noisy green alien invaders have been attributed to Jimi Hendrix, George Michael and even Humphrey Bogart. But where did they really come from? Presenter - Marnie Chesterton Producer - Fiona Roberts

Marnie Chesterton reveals how important the models and graphs are in informing government strategies for the Covid-19 pandemic. Christl Donnelly, Professor of Statistical Epidemiology at Imperial College London and Professor of Applied Statistics at the University of Oxford, and Dr Kit Yates, Senior Lecturer in Mathematical Biology at the University of Bath and author of 'The Maths of Life and Death', explain what epidemiological models can and can’t tell us about the progression of the disease, infection rates and death rates, and how testing will provide the essential data to make these models more accurate. They also give their take on the current inundation of social media with graphs and infographics created by non-epidemiologists - the ‘epidemic of armchair epidemiologists’. The European Space Agency’s Diego Urbina was one of the Mars500 participants. He spent 520 days in a human mission to Mars, shut up in a fake spacecraft with his fellow astronauts. So who better to get tips for home isolation from? Are you stuck in with the kids and want to try some science experiments that you can do at home? The Royal Institution is about to launch ExpeRimental Live - a live stream of home science experiments, designed to educate, entertain and inform your children with some cheap and easy science. And its existing ExpeRimental series of short films for parents are already available online. They were produced and directed by science teacher and writer Alom Shaha, who helps BBC Inside Science producer Jennifer Whyntie to have a go at making singing wine glasses with her children.

Last week, we promised we’d tackle your coronavirus and associated Covid 19 questions and you came up trumps. So this week we’re be talking about the latest from the lockdown, why there are bottlenecks in the testing system, how long the virus lives on your door handles and whether your dog can spread coronavirus. Joining us to answer your questions are Jonathan Ball, Professor of Virology at the University of Nottingham, and BBC Radio Science presenter and reporter Roland Pease. On Monday evening, Prime Minister Boris Johnson told the British people to ‘stay at home’. How stringent is the UK’s lockdown compared to other countries, and is it likely to be effective? The only real way we can know about the incidence and prevalence of the coronavirus is to test. Listener Andrew in Didcot wants to know more about testing and when antibodies appear in us. We discuss how the current testing system works, and why there are limitations on testing. One question that lots of scientists have been asking is: can people with mild or no symptoms spread the coronavirus? And so we delve into the evidence for asymptomatic spreading. Listeners Eleanor and Andy have been wondering about passing the virus from person to surface to person. Roland Pease looks into the virus’ survival on surfaces and elsewhere, and asks how that might be affecting spread. Finally, reporter Geoff Marsh tackles a quandary facing dog owners: Is it safe to walk your pet? Can dogs spread the virus? Presenter: Marnie Chesterton Producers: Fiona Roberts and Jennifer Whyntie

The government have announced that the controversial cull of badgers across England will begin to be phased out in the next few years. It will be replaced by vaccinating badgers for bovine TB. The cull is intended to cut tuberculosis in cattle and has killed at least 100,000 badgers since 2013. TB in cattle is a severe problem for farmers and taxpayers, leading to the compulsory slaughter of 30,000 cattle and a cost of £150m every year. However culling is thought to have failed because frequent trading of cattle and poor biosecurity on farms severely hampering efforts to tackle the crisis. Expert and ecologist Rosie Woodroffe at the Institute of Zoology, the research division of the Zoological Society of London, who has been trialling vaccinations for the past few years in Cornwall explains to Marnie Chesterton why it is highly desirable to move from culling to vaccination of badgers. Plus they discuss the parallels between this and the coronavirus outbreak in humans. Evolutionary biologist Neil Shubin at the University of Chicago, is also the author of the best-selling book on evolution – ‘Your Inner Fish’. In his new book, out this week, ‘Some Assembly Required – Decoding four billion years of life from ancient fossils to DNA’, Neil revisits the topic of evolutionary development and explains to Adam how we have now arrived at a remarkable moment—prehistoric fossils coupled with new DNA technology have given us the tools to answer some of the basic questions of our existence: How do big changes in evolution happen? Is our presence on Earth the product of mere chance? This new science reveals a multi-billion-year evolutionary history filled with twists and turns, trial and error, accident and invention. Presenter - Marnie Chesterton Producer – Fiona Roberts

Adam Rutherford explores what makes the new coronavirus so effective at making us ill. Jonathan Ball, Professor of Virology at Nottingham University, explains the structure of the virus and how it gets into our lungs. Evolutionary virologist at Cambridge University, Dr Charlotte Houldcroft talks to Adam about how labs are detecting the virus and how they are studying the way it mutates to understand how it's moving around the world. Kate Jones, Professor of Ecology at UCL, tells Adam how bats live with coronaviruses, but they don't get sick. She says the reason they have moved from bats to humans is because we have taken them out of their natural habitat into places like the wet markets of East Asia. Sarah Gilbert at Oxford University explains how her team is developing vaccines, and Jonathan Ball looks at work to repurpose existing drugs that may be used as treatment for Covid-19.

We have known for centuries about the toxic properties of lead, and we have known since at least 1876 that birds die of lead poisoning when they eat lead gunshot (which they do, thinking its grit). To address this, in 1999, the use of lead ammunition in England was restricted. These Regulations prohibit the use of lead ammunition in certain habitat (predominately wetlands) and for the shooting of all ducks and geese, coot and moorhen. However compliance with these Regulations is low. And what about other animals (game birds and game animals) hunted with lead ammunition? It’s only been since 2008 that it’s been demonstrated that that animals shot with lead were a risk to the health of people who ate them. Tiny particles of the toxic metal remain in the meat and are consumed. Children are especially vulnerable to lead toxicity, which causes problems with brain development. Leading Cambridge conservation scientist Professor Debbie Pain, has been studying lead in the environment for her entire career. So it’s good news to her that, 8 of the main UK shooting organisations have voluntarily agreed to ban lead shot for all live quarry by 2025. But is a voluntary ban is enough? And what are the Department of Food and Rural Affairs (DEFRA) doing to monitor and manage the problem? It can be a real treat to watch a meteor shower in the night sky and you can consider yourself lucky if you get to witness a fireball streaking through the atmosphere. But what the scientists in the Global Fireball Observatory really want is to find these fist-sized extra-terrestrial meteoroids where they land on Earth. One of the Fireball UK Network’s leaders, Luke Daly at the University of Glasgow, explains how, if we know where in the Solar system these rocks came from and we can analyse their make-up, we can learn a lot about how our Solar System was made. However surprising few of the 5000 tonnes of meteorites that land on our planet every year are retrieved. Most are sand-sized grains and many fall in the sea. But even tracking down these precious rocks on land is extremely difficult. So the Network has a suite of cameras watching the sky, and together with some clever number-crunching algorithms, they can track these events and narrow down where to search. But they still need the good citizens of Britain to help find them. If you want to get involved (and this is a good one for schools to take part in) email [email protected] or follow @fireballsUK on Twitter. We are fast learning that elements at the nanoscale have vastly different properties than they do in the form we can observe them. It’s proving to be a rich field for changing the properties of materials, and inventing new substances that might be of use in medicines, in electronics, and much more. Inside Science’s Maddie Finlay went to meet Stephen Evans from the University of Leeds, where they have been tinkering with a substance that definitely doesn’t glister even though it’s gold. Producer: Fiona Roberts

Composters - we need you! Or rather materials scientists at UCL, Mark Miodownik and Danielle Purkiss, need you to take part in their Big Compost Experiment. Launched back in November, the team asked members of the public to fill in an online questionnaire about their composting and recycling habits. With special reference to plastic packaging labelled as 'compostable', they want you to see whether your compost bin at home can break down these products. Despite starting in the coldest season, where compost production really slows down, they've had some success. To take part, go to https://www.bigcompostexperiment.org.uk/ One particular infectious disease (Covid-19) is dominating the headlines, but it's by no means the only one we should be concerned about. There's an infectious disease crisis that is longstanding, and one of the most significant threats to global health. It’s the on-going antibiotic resistant crisis. Antibiotics kill bacteria, but bacteria evolve resistance very quickly, and because of overuse of antibiotics, we’ve effectively driven the evolution of many disease causing bacteria to be resistant to our best antibiotics, thus rendering them redundant as drugs. On top of that, we haven’t found any new classes of antibiotics for many years. And the cost of developing new drugs is very high – billions, and the financial incentive for developing antibiotics is low. So this is a perfect storm. A new study this week shows a glimmer of light in the quest to find new antibiotics, via artificial intelligence. Lena Ciric, a microbiologist at University College London, explains how the new drug Halicin was found and the promise it holds as a new antibiotic. Slapstick is one of the most universally appreciated comedy styles. The physical comedy that made Charlie Chaplin, Laurel & Hardy and even Mr Bean so popular has transfixed and entertained generations. But how has it endured the test of time? Why do we enjoy seeing characters in pain? Or is it something deeper rooted that it tells us about the human condition? Laughter is a social action – we do it to show we understand a joke and to signal to people that we get along with them. 'Told By An Idiot' is a theatre company exploring the divide between comedy and tragedy who are currently performing a slapstick style show about the relationship between Charlie Chaplin and Stan Laurel, who had been his understudy. Hannah Fisher has been to see the show. Producer - Fiona Roberts

Adam Rutherford is joined by Professor of Virology at Nottingham University, Jonathan Ball, to help answer some of your questions on the latest coronavirus outbreak. Will it become endemic, and once infected and recovered how long are we resistant to the virus? And can face masks and alcohol hand gels help prevent infection? In the 1870's the scientific research ship, HMS Challenger, sailed all the world's oceans measuring sea temperatures, ocean depths and sampling the geology of the seabed. But it's the seawater samples, containing microscopic zooplankton, preserved for 130 years which intrigued climate scientist Dr. Lyndsey Fox. She has been measuring the thickness of the shells of Foraminifera - tiny single-celled organisms - as a way of measuring how much the ocean has acidified over time. The shells are made of calcium carbonate, that is much harder to accrete when the pH drops. Theoretical physicist Sean M. Carroll is very good at explaining the unexplainable. He chats to Adam about his latest book - Something Deeply Hidden: Quantum Worlds and the Emergence of Spacetime. Producer: Fiona Roberts

For the past 220 years, Ordnance Survey have been mapping Great Britain with extraordinary accuracy. But as Gareth discovers when he visits their HQ in Southampton, GB's master map is not a static printed document. It's a 2 petabyte database which is updated up to 20,000 times a day. This adds up to 360 million updates a year. Since the development of the theodolite and the first detailed map in 1801 of the county of Kent, Ordnance Survey have used cutting edge technology, not only to map our lands, but to manipulate, understand and ask questions of the geography of our natural landscapes and built environment. Voices on the train, public address announcements at the station, automated telephone banking, Alexa and Siri. We are surrounded by electronic voices. But very little research has been done of how we respond to synthetic speech. To investigate the impact of artificially generated voices in our lives, BBC R&D together with our favourite acoustic engineer, Professor Trevor Cox of the University of Salford, has just launched a study. The Synthetic Voices and Personality Test, is an online test we want you to take part in.

The latest space mission to the Sun is due to launch on Sunday. SolO, the European Space Agency's Solar Orbiter, will loop around our star in an elliptical orbit, sling-shotting around Venus. Professor Richard Harrison at the Rutherford Appleton Laboratory has been on the mission from its conception, he details the instruments and what they're hoping to discover about the Sun and its impact on space weather back here on Earth. If chemicals in cigarette smoke or exposure to UV light played a role in causing a cancerous tumour, we can now see this evidence in the DNA. These and other causes of cancer are being catalogued by a huge international study revealing the genetic fingerprints of DNA-damaging processes that drive cancer development. Professor Mike Stratton, is director of the Wellcome Sanger Institute and author of one of many papers released in Nature and associated journals this week that detail the results of the Pan-Cancer of Whole Genomes Consortium. Cancer is not a modern disease. Evidence in bones and remains reveal our ancient ancestors also suffered. Dr. Kate Hunt is a paleo-pathologist studying paleo-oncology, a very specific, very recent branch of archaeology, looking through ancient burial sites, artefacts and literature for signs of cancer. Presenter - Marnie Chesterton Producer - Fiona Roberts

With the recent coronavirus outbreak spreading around the world, and concerns about people being infectious before they exhibit any symptoms. Professor of Virology at Nottingham University Jonathan Ball explains infection rates, quarantines and why he's worried about it spreading to the developing world. 'Alice in Typhoidland' is a new exhibition in Oxford recording how that city dealt with typhoid. It’s called that after one of its 19th century residents, Alice Liddell (the girl after whom Alice in Wonderland was named). Her father Henry Liddell was the Dean of Christchurch College and together with his friend Henry Ackland was instrumental in closing off Oxford's open sewers and thereby combating some of the causes of the disease. The exhibition also explores the fate of Typhoid Mary – one of the most famous asymptomatic disease carriers in history. Exactly 200 years ago, 30th January 1820, at 3:30 local time, the continent of Antarctica was spotted for the first time by a British expedition captained by Edward Bransfield, on the Merchant Ship The Williams. But they weren’t the very first: 3 days earlier - on 27 January - a Russian expedition led by Fabian Gottlieb von Bellingshausen and Mikhail Lazarev spotted what is now known as the Fimbul Ice Shelf. The UK Antarctic Heritage Trust is spearheading celebrations.

With news reports moving as quickly as the virus may be spreading, the latest coronavirus outbreak which is thought to have started in Wuhan in central China is fast becoming a global health concern. Adam Rutherford speaks to BBC Inside Science's resident virologist Professor Jonathan Ball from Nottingham University, who says one of the most urgent things to do is to find out where the virus came from, and what animal it jumped to humans from. The Anabaptist Amish communities are some of the fastest growing populations on the planet. They came to the US from the Swiss-German border in the 18th and 19th centuries and have maintained their plain, simple community-minded way of life. Partly because they all descended from the same geographical area and partly because they tend to marry within their own communities, they can suffer from a particular spectrum of genetic disorders. Professor Andrew Crosby and Dr. Emma Baple from Exeter University have been studying these diseases, including a number new to medicine, and in return they are helping the Amish to understand and treat some of these debilitating diseases. He may currently sound more like a sheep baa-ing, but in a proof of concept experiment, Professor David Howard, an electrical engineer at Royal Holloway University of London, has been able to scan, 3D print and electronically reanimate the vocal tract of Nesyamum, a 3000 year old Egyptian mummy. The eventual hope is to recreate his tongue and try to get him to sing. Producer - Fiona Roberts

Science is built upon the idea that results can be verified by others. Scientists do their experiments and write up their methods and results and submit them to a journal that sends them to other scientists, who check them and if they pass muster, the study gets published for further scrutiny. One of the keystones of this process is that results can be reproduced. If your results can’t be replicated, something is amiss. Over the last few years, particularly in the field of psychology, many high profile findings have not been reproduced. Now, the same problems that have plagued psychology are spilling over into other areas. This week, a study showed that ocean acidification does not significantly alter fish behaviour, as had been reported several times before. Adam Rutherford discusses the crisis with Matthew Cobb, Professor of Zoology at Manchester University. ESA’s Aeolus mission was launched in August 2018. It’s one of the European Space Agency’s Earth Explorer satellites. The Aeolus satellite uses lasers to monitor the wind by firing an ultraviolet laser beam into the atmosphere and catching the light’s reflection as it scatters off molecules and particles carried along in the air. It was planned to be very much a proof of principle mission, testing the science, with longer-term plans for a whole constellation of wind monitoring satellites. But Aeolus has performed so well in the tests that, unusually for meteorological science, the results are now considered robust enough to be inputted into the European Centre for Medium-Range Weather Forecasts models. The UK is aiming to phase out conventional combustion engines in favour of more energy-efficient, less polluting electric vehicles by 2040. In response to a listener’s question on the cleanliness of these machines, BBC Inside Science reporter, Tristan Varela, conducts an investigation in the streets, garages, and laboratories of London. He finds that electric cars are relatively clean in the UK, where energy generation from renewable sources has recently overtaken fossil fuels. However, sales of new electric cars are still heavily outweighed by large, fossil fuel hungry, SUVs. But some people are instead converting existing cars to make their vehicles more environmentally-friendly. Producer - Fiona Roberts

2019 was the hottest and driest year on record in Australia. The Indian Ocean Dipole and the Southern Annular Mode weather systems, plus existing drought conditions, all primed the continent for the horrific fire season currently raging in the east and south east of the country. Climate scientist at the University of New South Wales Sarah Perkins-Kirkpatrick is in no doubt global warming played a role in making these the worst fires in recent history. Making matters even worse is that the ferocity of the bush-fires is creating its own weather. Nicholas McCarthy at the University of Queensland studies fire-induced weather and he explains how this can help spread the fires further. January is also Veganuary, a chance for you to try being vegan for 31 days. The reasons for giving up animal products in your diet are varied, from reducing your carbon footprint to not eating animals and getting healthy. Reporter Geoff Marsh is interested in the evidence in favour for and against a vegan diet. A signal in April 2019 picked up by the LIGO Livingston Observatory has been confirmed as the gravitational ripples from a collision of two neutron stars. LIGO Livingston is part of a gravitational-wave network that includes LIGO (the Laser Interferometer Gravitational-wave Observatory), and the European Virgo detector. Producer - Fiona Roberts

Our genomes are more than just an instruction manual for our bodies. They are maps, diaries, history books and medical records of our and our ancestor's lives...if you know how to read them. In the second part of BBC Inside Science's special, series, Adam Rutherford, UCL geneticist Lucy van Dorp and other scientists discover how travel and even culture of our ancestors can be decoded in our DNA today.

Our genomes are more than just an instruction manual for our bodies. They are maps, diaries, history books and medical records of our and our ancestors' lives.....if you know how to read them. In this programme and the next Adam Rutherford is joined by UCL geneticist Lucy van Dorp and other scientists who are cracking these genomic codes to tell the human story. This week they explore how sex and disease over the past few thousand years has left indelible marks on our DNA.

Adam Rutherford talks to Chris Lintott about the citizen science platform he set up ten years ago. Zooniverse is a place where the public can help scientists analyse huge swathes of data. Projects such as spotting distant galaxies, counting penguins and tagging WW2 diaries have all has a huge boost thanks to the people-power of the Zooniverse. The Indonesian volcano Anak Krakatau, which means 'Son of Krakatoa', was born out of the ashes of the mega volcano which erupted and collapsed in the 1880s. Last year the island volcano Anak collapsed, causing a tsunami which killed 400 people. The collapse of millions of tonnes of rock into the ocean has now been mapped and chunks of rock, the size of office blocks, have been found tossed kilometres from the island. It really brings home how dangerous these volcanoes can be. BBC Inside Science producer Fi is always scribbling and doodling during interviews. It turns out she is a visual thinker and she compulsively draws the science being discussed. She is not alone: many scientists working in fields involving complex maths and physics resort to pictures to illustrate what's happening. But not everything in science can be reduced down to a 2D sketch and not everyone needs a visual aid. Marnie Chesterton finds the scientists who can look at an equation, and 'see' in their heads, the graph it describes. Others get intensely annoyed at analogies that just aren't quite right - like spacetime being a ball on a rubber sheet. She asks a physicist, a philosopher and a mathematician about the relationship they have between maths, reality and our senses. Producer - Fiona Roberts

A cave painting in Sulawesi, Indonesia, has been dated and is at least 43,900 years old. The mural portrays a group of part-human, part-animal figures (called therianthropes), hunting large mammals with spears and ropes. It is thought to be the oldest representation of a hunting scene in human history, and perhaps Homo sapiens' oldest known figurative rock art. Adam Brumm at Griffith University in Brisbane is part of an international team that has been exploring this cave complex. He speculates with Adam Rutherford about who the artists were and what they were trying to depict. A famous Russian farm fox study has been running since the 1950’s. The researchers essentially took foxes bound for the fur trade and selected for tameness by choosing to keep and breed from the animals that showed less fear and more friendliness towards humans. After years of selection, the tamer foxes also showed physical changes (floppier ears, curlier tails, white spots, redder fur) as well as changes in breeding times. As a way to study the evolution of domestication of animals, this study is taught to students all over the world. However a chance discovery at a Fox Museum on a Canadian Island, shows the original foxes were taken from fur farms in Canada and had already been bred for tameness. Elinor Karlsson at the Broad Institute at MIT and Harvard University discusses with Adam whether we have to rethink the Animal Domestication Syndrome. Producer - Fiona Roberts

Reports from the UN Climate Change Conference (COP 25) in Madrid are saying that global warming is increasing and that we're not doing enough, fast enough, to change things. The World Meteorological Organisation's provisional State of the Climate 2019 report lists atmospheric carbon dioxide reaching record levels. Global mean temperatures for Jan-Oct 2019 were 1.1+/-0.1 degrees Celsius above pre-industrial levels. The Arctic ice extent minimum in Sept 2019 was the second lowest on satellite record. Tropical cyclone Idai was the strongest cyclone known to make landfall. These are all concerning statistics. According to the Global Carbon Emissions figures that have just been released, carbon dioxide in the atmosphere is still increasing: the slightly good news is that the rate of increase has slowed. Adam Rutherford talks to climate expert at the Tyndall Centre at the University of East Anglia, Corinne Le Le Quéré, to find out more. “Safe as houses" is a cliché built on the solidity of the buildings we put up. But at Bath University engineers are working in the opposite direction. They are asking just how strong does a building have to be - especially in an age of ever taller sky-scrapers, which inevitably sway, particularly when the wind picks up. It's not that there's any danger they'll fall down - but the movement can be unsettling to the occupants. So they've developed a virtual tower - a windowless cabin not much bigger than a caravan stuck on top of a set of hydraulic pistons with virtual reality screens to mimic window views that allow psychologists to monitor volunteers' experiences of living and working in high, flexible spaces. Our Sun is so much more than a giant ball of burning gas. Its core is a nuclear reactor which creates billions of looping and tangling magnetic fields. Its layers are puzzling variations of hot temperatures and its solar wind has some very peculiar properties. These are just some of the reasons NASA launched its Parker Solar Probe in August 2018 on a mission to get close (3.8 million miles) to our star’s surface and study its properties. The first scientific reports from the mission are out and solar expert Professor Lucie Green at UCL reveals what the car-sized, armour-plated craft has been finding out so far. She says "our Sun is more dynamic than expected and we might be getting clues to why the sun spins more slowly than theory predicts." Producer - Fiona Roberts

Palm oil is now such a dirty word for household products and processed food, that it often hides behind a list of dozens of pseudonyms (from the ubiquitous sodium laureth sulphate to the slightly more obvious palm kernel oil, to the totally opaque vegetable oil). It’s becoming a major global concern, and there is on going debate between enforcing a ban or shifting to more sustainable production. It’s always complicated, but as we’ve learned so many times in the past, we have to tread carefully to avoid the unintended consequences of making snap environmental decisions. Indications that an outright ban might be more environmentally harmful because of the lower yield and more land needed by alternative vegetable oil crops, so should we be paying more attention and even championing sustainably sourced palm oil? In the UK, Chester has become the first city to source its palm oil entirely from sustainable sources. Cat Barton and Simon Dowell from Chester Zoo have recently returned from the EU where they were advising on the creation of more sustainable palm oil cities on the continent. Alongside Indonesia, Malaysia is one of the biggest producers of palm oil. As of 2015, the country was covered in over five and a half million hectares of oil palm, nearly a third of which is found in Sabah, the north eastern state in Borneo. Sabah is home to many endangered species, like pygmy elephants and orang-utans. Many of them are found in reserves but they often need to move between these national parks to ensure they have enough food or to find new territories but also to ensure a healthy mix of genetics within populations. To do this, they need to travel through plantations, which can cause many human-wildlife conflicts, especially when they can sometimes cause thousands of dollars worth of damage in one night as they pass through. This is particularly true of elephants, who love to eat the oil palm fruit bunches, but it isn’t isolated to palm oil. Elephants can frighten people or knock down trees in softwood plantations. Graihagh Jackson reports from Sabah. Virtual Reality has come on leaps and bounds for the visual and auditory senses, but in the realms of haptics, or touch, it’s had to rely on wiring up the user with electrodes which produce vibrations to simulate sensory experiences. But now John Rogers and his team at Northwestern University have developed a wireless soft, flexible ‘skin’ which can be layered gently over the wearer’s own skin to produce a more comfortable and realistic haptic interface with applications not just for gaming, but for tactile social media applications and even for controlling prosthetics.

The effects of human-made noise on the natural world has been surprisingly little studied. Hanjoerg Kunc at Queen's University in Belfast has collected all experimental data on the effects of anthropogenic noise on wild animals and found it to be overwhelmingly harmful., And Cambridge University's PhD student Sophia Cooke is looking at the impact of roads, including road noise on British birds, and the impact could be huge. Last week we spoke to Jane Rickson at Cranfield University about how healthy soils are a good defence against the effects of, and indeed the process of, flooding. Many farmer listeners emailed in to tell us about their experiences with no till and minimum disturbance agriculture. Simon Jeffery at Harper-Adams University takes Adam through some of the points raised. Last November, drilling began in Redruth, Cornwall to see if geothermal heat could be tapped from the hot rocks below. Graihagh Jackson went to catch up with the project and met with Lucy Cotton – the project geologist for the United Downs Deep Geothermal Power project. Producer: Fiona Roberts

The UK's soils are the first line of defence against flooding, but the condition of the soil is vital to how well it can soak up and slowly release rainwater. Jane Rickson, Professor of soil erosion and conservation at Cranfield University, explains to Adam what makes a healthy soil and what farmers can do to try to prevent floods. "Spice" is a catch-all phrase for a large variety of psycho-active compounds - commonly called legal highs. They interact with the same receptors in the brain as cannabis does. They're commonly sold sprayed onto common herbs that users smoke, so that dose, as well as variety and purity are completely uncontrolled by the time they're taken. And that's where the problems start in A&E departments and the blue-light services, because patients can show up with severe symptoms of psychosis with little clue as to what's caused it. And until now there's been no quick and easy test. Roland Pease went to Bath University where biochemist Chris Pudney and his team have developed some portable kit using ultraviolet to throw light on the spice users are smoking. The Ultra Low Emission Zone (ULEZ) was brought in in London in April 2019 to improve air quality in the centre of the city. In 2020 cities including Bath, Leeds and Birmingham are also bringing in ‘Clean Air Zones. Alastair Lewis is professor of atmospheric chemistry at the University of York and he explains what these schemes are targeting and whether we can measure whether they are working.

The Prime Minister Boris Johnson announced an indefinite moratorium this week on mining of shale gas by hydraulic fracturing, aka fracking, in the UK, citing fears of earthquakes and seismic activity caused by fracking in the past. In August this year, a 2.9 magnitude earthquake was recorded at the Preston New Road fracking site in Lancashire, which prompted an immediate shutdown, as required by the strict protocols that we have in place. Adam Rutherford talks to Dr James Verdon, a geophysicist at Bristol University and a co-author of one of the Oil & Gas Authority studies on the Preston New Road, about the science of fracking. Bloodhound is the latest British attempt at the supersonic land speed record. All this week Wing Commander Andy Green has been burning across a dried out lake in the Kalahari Desert, as he and his team are building up to break the sound barrier at 740mph, and his own land speed record of 763 mph. BBC science correspondent Jonathan Amos reports from the trackside. The Big Compost Experiment is a new citizen science project about the wonderful, rich, fruity and essential substance you can produce by doing not that much at all. Architect Danielle Purkiss and Mark Miodownik, material scientist at UCL tell Adam why they are launching this experiment. The planet Mercury, messenger of the Gods, passes between us and the Sun on average just thirteen times a century. This astronomical event will be visible in the UK – weather permitting – next Monday, 11th November. Solar physicist Lucie Green explains how to see the transit of Mercury.

Since the human genome was first sequenced nearly 20 years ago, around a million people have had theirs decoded, giving us new insights into the links between genes, ancestry and disease. But most of the genomes studied have been in people of European descent. Now a decade-long collaboration between scientists in the UK and in Uganda has created the largest African genome dataset to date. Dr Deepti Gurdasani discusses her research with Gaia Vince. After 7 years of orbiting the Earth and sending us important information about space weather, NASA’s Van Allen Probes are retiring. Professor Lucie Green from UCL explains how the sun can spit out superhot plasma and streams of high energy particles in our direction. We are mostly protected by the Earth’s magnetic field - but not always. The worst-case scenario is that the radiation could disrupt navigation satellites and bring down electrical power supplies. Professor Green will be keeping an eye on space weather with a new spacecraft. Growing evidence shows that repeatedly getting your head knocked around during competitive sports can lead to long-term serious consequences. The head doesn’t necessarily need to be the target of the blow – a hard tackle can ricochet through your body giving your head a jolt.

Switching to 100% organic food production in England and Wales would see an overall increase in greenhouse gas emissions. Although going fully organic would produce fewer direct emissions than conventional farming, researchers say it would limit food production. Making up the shortfall with imports from overseas would increase overall emissions. But is the sustainability of our food production about more than greenhouse gas emissions alone? Professor Dave Reay is Chair in Carbon Management & Education at the University of Edinburgh, and has recently acquired a smallholding in Scotland. He discusses the study and answer your questions about sustainable food and population growth. Seagulls have become notorious food thieves in recent times as they move into towns to find new habitats and sustenance. Scientists at the University of Exeter have found that if you stare at a herring gull, it’s much less likely to steal your chips. Reporter Graihagh Jackson went to Falmouth to meet with researchers Madeleine Goumas and Neeltje Boogert to see the tactic in action. More than 800,000 people in the UK live with dementia, which is an umbrella term for over 200 specific diagnoses that all involve some form of neurodegeneration. Epidemiological evidence has suggested that high dietary salt intake may somehow be linked to developing cognitive impairment. A study released this week shows a mechanism for how this might occur biologically in the brains of mice who were fed a high salt diet. Professor Carol Brayne is Director of the Cambridge Institute of Public Health at the University of Cambridge, and she explains how this new research fits into the field and our understanding of dementia’s causes.

Zoonotic diseases are infections that transfer from animals to people, and include killers such as bubonic plague, malaria, ebola and a whole host of others. Trying to understand how diseases make the leap from animals to humans – so called spillover – and how outbreaks occur is a crucial part of preventing them. But outbreaks are complex and dynamic, with a huge number of factors playing a role: What animal is hosting the disease, the environment in which it lives, the changing climate, human presence and impact on the local area and many other factors. Kate Jones is professor of ecology and biodiversity at University College London, and has been tracking ebola in Africa. Her team has just published a new study that models how and when spillover might happen in the future. On the lushly forest islands of French Polynesia, there lives a very special snail. Partula are around 100 species of tiny snails who give birth to live young and feed on decomposing plants. Each species is uniquely adapted to a particular ecological niche. But in 1967, the highly edible Giant African Land Snail was introduced to the islands as a source of food. They quickly became pests, and in response, the French Polynesian government then introduced carnivorous Rosy Wolf Snails - aka Euglandina rosea - to quell the spread of the introduced Giant Land snails. Reporter Naomi Clements-Brode picks up the story with scientist Ann Clarke, along with Dave Clarke and Paul Pearce-Kelly at ZSL London Zoo. Finally this week, malaria is, as best we can account for it, the single greatest killer in human history. The vast majority of malaria is caused by a type of single celled protozoan called Plasmodium falciparum, carried by mosquitos. But according to new research published this week, it started out around fifty thousand years ago not in us, but as a gorilla disease, and in one particularly unlucky gorilla, two simultaneous infections prompted the mutation and rise of the plasmodium parasite that would go on to kill millions. Dr Gavin Wright from the Wellcome Sanger Institute in Hinxton lead the team behind this molecular archaeology.

Extinction Rebellion is in the news with its stated aim of civil disobedience and protest, and goal to compel governments around the world to act on the climate crisis. Meanwhile, the UK government this week announced that it was overruling its own Planning Inspectorate, by approving in principle new gas-fired turbines at the Drax power station in North Yorkshire. The Inspectors had advised that the new developments would undermine UK climate policies on carbon emissions. In the UK we are committed to reaching net zero carbon emissions by 2050, in order to comply with our ratification of the Paris agreement, which aims to limit global temperature rise to 1.5 degrees. So what are we to do? Are the government policies and commitments enough, and are we sticking to them? Adam Rutherford discusses these questions with Jim Skea, Professor of Sustainable Energy at Imperial College, London, and co-chair of the Working Group tackling reducing emissions of greenhouse gases, part of the Intergovernmental Panel on Climate Change. This week has been the annual jamboree and drama of the Nobel Prizes: the announcements of the biggest gongs in science. The Physiology or Medicine Prize went to William Kaelin from Harvard University, Sir Peter Ratcliffe from the Crick Institute in London and Gregg Semenza from Johns Hopkins University for their work on how the body responds to changing oxygen levels. The Physics Prize went to James Peebles of Princeton for cosmological discoveries, and Michel Mayor and Didier Queloz, then at the University of Geneva, for the 1995 discovery of the first exoplanet, 51 Pegasi b. And the Chemistry Prize was awarded for the invention of something that we utterly rely on every day, the lithium battery. The winners are John Goodenough, University of Texas at Austin, Stanley Whittingham, State University of New York, and Akira Yoshino of the Asahi Kasei Corporation in Japan. These awards offer plenty to discuss, so Adam is joined by Lisa Kaltenegger, Director of Carl Sagan Institute & Associate Professor of Astronomy, Andrew Pontzen, Professor of Astrophysics at University College, London, and reporter and presenter Marnie Chesterton, who spent some time with chemistry laureate John Goodenough.

In November 2018 news broke via YouTube that He Jiankui, then a professor at Southern University of Science and Technology in Shenzhen, China had created the world’s first gene-edited babies from two embryos. The edited gene was CCR5 delta 32 - a gene that conferred protection against HIV. Alongside the public, most of the scientific community were horrified. There was a spate of correspondence, not just on the ethics, but also on the science. One prominent paper was by Rasmus Nielsen and Xinzhu Wei’s of the University of California, Berkeley. They published a study in June 2019 in Nature Medicine that found an increased mortality rate in people with an HIV-preventing gene variant. It was another stick used to beat Jiankiu – had he put a gene in these babies that was not just not helpful, but actually harmful? However it now turns out that the study by Nielsen and Wei has a major flaw. In a series of tweets, Nielsen was notified of an error in the UK Biobank data and his analysis. Sean Harrison at the University of Bristol tried and failed to replicate the result using the UK Biobank data. He posted his findings on Twitter and communicated with Nielsen and Wei who have now requested a retraction. UCL's Helen O'Neill is intimately acquainted with the story and she chats to Adam Rutherford about the role of social media in the scientific process of this saga. The Herculaneum Library is perhaps the most remarkable collection of texts from the Roman era. Discovered two centuries ago in the villa of Julius Caesar’s father in law, many of the papyrus scrolls bear the writings of the house philosopher, Philodemus. Others are thought to be the works of the philosophers and poets he admired. However, the big drawback is that the villa was buried in the eruption that engulfed Pompeii, and the heat from the volcanic ash turned them all to charcoal. To make life even more difficult, the ink the scribes used was also made of carbon – think black on black. However, now a team from the University of Kentucky are hoping to decipher the texts using X-rays, and have just scanned two complete scrolls, and some fragments at the Diamond Synchrotron in near Oxford. When renowned author Bill Bryson decided to apply his unique eye for anecdote and trivia to the human body he thought he's start at the head and work down. But as he reveals to Adam, it's a lot more complicated and interconnected than that. His book "The Body - A Guide for Occupants" is an indispensable guide to the inner workings of ourselves.

The Intergovernmental Panel on Climate Change's special report on the oceans and cryosphere makes pretty grim reading on the state of our seas and icy places. Ocean temperatures are rising, permafrost and sea ice are melting, sea levels are rising and marine life is either moving or suffering the effects of temperature changes and acidification. Dr Phil Williamson, research fellow at the University of East Anglia, worked on the report and he explains to Adam Rutherford how the watery and icy parts of the planet connect to the atmosphere and climate. It's a good job the small, round, spouted clay vessels found in 3000 year old baby graves in Bavaria weren't washed up very well. Crusts of food deposits have shown that these early baby bottles were used to give infants milk from ruminants such as cows, goats and sheep. This discovery, and previous discoveries of even earlier spouted vessels in Europe, indicate that settling down from hunter-gathering to agriculture in prehistoric Iron and Bronze-Age people impacted all ages. Dr Julie Dunne, organic geochemist at the University of Bristol, thinks that this more settled lifestyle with domesticated animals and cereals to supplement a baby's diet, led to earlier weaning and maybe more babies. Caroline Criado Perez’s ground-breaking gender bias exposé wins the 2019 Royal Society Science Book Prize. 'Invisible Women: Exposing Data Bias in a World Designed for Men' by writer, broadcaster and feminist campaigner Caroline Criado Perez, becomes the 32nd winner of the prestigious Royal Society Insight Investment Science Books Prize. Caroline explains to Adam how a range of case studies, stories and new research highlights ways in which women are ‘forgotten’ on a daily basis. From government policy and medical research to technology, media and workplaces, she exposes the lack of gender-specific data that has unintentionally created a world biased against women Producer - Fiona Roberts

On Friday, 20 September, a powerful icebreaker called The Polarstern will set sail from Tromsø, Norway, with the aim of getting stuck into the polar ice. The plan is for the ship to spend the next year drifting past the North Pole, and this should enable scientists to collect unprecedented data on the Arctic. The Polarstern is the ‘mothership’ of a substantial international collaboration called the Multidisciplinary drifting Observatory for the Study of Arctic Climate (or project MOSAiC). Scientists from over seventy research institutions across 19 different countries are involved, and a total of six hundred experts will be aboard throughout the expedition. They plan to construct a ‘research city’ around the vessel with different neighbourhoods, each focused on a particular scientific area including: ecosystem, bio-geo-chemistry, ocean, atmosphere and sea ice. Adam spoke to UCL’s Professor Julienne Stroeve, who will be aboard The Polarstern for two months during the Arctic winter, looking at the depth and density of snow in order to improve our understanding of the Arctic, and enhance our ability to predict effects of global climate change. The residents of the Bahamas are still struggling to come to terms with the devastation of Hurricane Dorian (which hit 2 weeks ago) and also with the additional impact of Tropical Storm Humberto which reached the islands on Friday night, bringing more heavy rain and more strong winds. But the human population is resilient and they will eventually rebuild and resume their lives on the Caribbean islands. But for the Bahama nuthatch, it’s thought that Dorian was the final straw. The endemic bird, is (or was) one of the rarest birds in the western hemisphere, in fact it was already thought extinct (after the damage wrought by Hurricane Mathew in June 2016) until last year when Professor Diana Bell and her team of conservationists from the University of East Anglia rediscovered it. But now, after the hurricane it is feared lost forever, and it may not be the only irreversible ecological loss for the Bahamas. Tim Smedley's book 'Cleaning the Air: The Beginning and End of Air Pollution' is shortlisted for the Royal Society's science book prize. Tim tells the full story of air pollution: what it is, which pollutants are harmful, and where they come from. It's scary stuff, but there is good news that air pollution can be avoided and drastically reduced with sensible measures. Producer - Fiona Roberts

One of the most fundamental developmental stages we humans go through is extremely poorly understood. The first few days of the embryo, once it's been implanted in the womb is incredibly hard to study. Yet it's the time when the majority of pregnancies fail. Professor Magdalena Zernika-Goetz at Cambridge University is a leader in the field of making 'model embryos' in both mice and humans. Model embryos until now have been grown in the lab from donated fertilised eggs, but these are hard to come by and governed by strict laws and ethical guidelines. Now researchers in the University of Michigan have used human pluripotent stem cell lines (originally isolated from embryos, but kept and nurtured as clumps of dividing cells in petri-dishes for many years) to make a model embryo that has shown signs of development and organisation in the crucial 7-10 day window. Magdalena and Gaia Vince discuss how helpful these will be to understanding crucial early stage pregnancies and as a tool to test drugs, treatments and disease processes. The ethical side of growing human embryos from stem cells is addressed by Stanford University ethicist Professor Hank Greely. Physicist Paul Steinhardt has spent a great deal of his career trying to understand crystals with seemingly impossible five fold symmetries. Most of this was with pen and pencil in his Princeton laboratory. But in his Royal Society Science Book Prize shortlisted book, 'The Second Kind of Impossible', he documents his adventurous quest for these 'quasicrystals' in the wilds of Russia's Kamchatka Peninsular. In 1957 the River Thames was so polluted it was declared ecologically dead. But since then The Zoological Society of London in partnership with over 30 conservation and research organisations have been working to improve the health of the River Thames and bring back the plethora of life and biodiversity. They are set to publish the first complete analysis of the river in over 60 years this Autumn. They're calling it 'Mother Thames' in recognition of the now nurturing nature of one of Britain's biggest rivers. Presenter - Gaia Vince Producer - Fiona Roberts

Global Positioning System, or GPS is perhaps the best known of the satellite navigation systems, helping us find our way every day. Back in the 1970's Bradford Parkinson and Hugo Fruehauf were two of the inventors who miniaturised atomic clocks and launched them in Earth orbit satellites. This was part of the US Department of Defense's plan to track ships and aircraft and guide targeted missiles. In the intervening years, Brad and Hugo had no idea just how far the civilian applications of GPS would go. Alongside Richard Schwartz and James Spilker, they have just been awarded the prestigious the Queen Elizabeth Prize for Engineering. The age of silicon chip based computing could be coming to an end. Difficulties in shrinking silicon transistors, or switches, into ever smaller processors led researchers at MIT to search for alternative semiconducting materials to replace them. Cue carbon nanotubes, tubes of carbon atoms many tens of thousands of times narrower than a human hair. Electrical engineer Max Shulaker and his team have overcome spaghetti-like tangles of CNTs and varying levels of conductivity to create a 16bit processor. He says that rather than a straight forward replacement to silicon, the initial hope is that CNT chip technology can be added to existing silicon wafers. Steven Strogatz and Monty Lyman have been shortlisted for the Royal Society Insight Investment Science Book Prize this year. In "Infinite Powers", Professor of applied maths at Cornell University, Steven Strogatz tells Adam Rutherford the story of calculus and why his book has a warning saying "this book is dangerous, it will make you love mathematics!" And in "The Remarkable Life of the Skin" Dr. Monty Lyman takes Claudia Hammond on an intimate journey across our surface. They discuss advances in skin treatments, new research on the importance of our diet and our skin and the vital role our largest organ plays in our lives.

Satellite data has shown an 85% increase in the number of fires across Brazil this year. There are more than 2,500 fires active across the Amazon region. This represents the most active number of fires since 2010. The increase in fires has been attributed to deliberate deforestation and clearing for agriculture or mining. The new president of Brazil, Jair Bolsanaro, supports the commercialisation of the Amazon forest and this is said to have encouraged the wide scale burning. Professor of Earth System Science at the University of California Irvine, Jim Randerson and Luiz Aragão of Brazil’s National Institute of Space Research are just two scientists concerned about the destruction and carbon emissions from the extensive burning.

Perhaps you’ve been lucky enough to spot the uncommon black grey squirrel in the UK. The bizarre mutation that causes a change in fur colour has finally divulged its historic evolution. Dr Helen McRobie at Anglia Ruskin University studies the black version of the introduced grey squirrel. She explains to Gareth Mitchell how the grey squirrel might have got the genetic mutation for black fur back when it was in North America. She describes how she stumbled across a finding that questions how we define a species. Nuclear fusion – it’s the energy source of the future, and always will be! Yes, it’s one of those technologies that was about thirty years away in the 1980s when they built a massive fusion lab in Culham in Oxfordshire. And, thirty years on, they’re still trying to crack it. Part of the challenge is building containers that can handle some of the hottest, and trickiest, matter known to humans – plasma. At the Joint European Torus (or JET), they’ve been busy revamping their thirty-five-year-old kit. It’s to keep the fusion research going whilst the scientists wait for a shiny new facility to open up in Southern France. It’s all about working on reactions like those that fuel the Sun – squashing atoms together rather than pulling them apart. A brand new series of landmark tests at JET is kicking off in the months ahead. Roland Pease went to the labs to find out just where the UK is in fusion right now. The 2019 Royal Society Insight Investment Science Book Prize winner will be announced in late September. The shortlisted authors will be announced next week but before then Adam Rutherford chats to two of the judges, Professor Sir Nigel Shadbolt, and best selling fiction author, Dorothy Koomson, about what makes a great popular science book and what in particular the judges are looking for in this year’s competition.

Following the simultaneous outages of two UK power plants last Friday, affecting nearly 1 million people across the country, we at Inside Science wanted to get back to the basics of electricity and get our heads round how the National Grid keeps the nation running. Keith Bell explains the difference between AC and DC (Alternating and Direct current), and why it's essential to keep the frequency of the grid steady at 50Hz. They’re calling it ‘Mission Jurassic’. A site so full of dinosaur bones that it would most probably keep a thousand palaeontologists happy and enormously busy for a thousand years. The Children’s Museum of Indianapolis (TCMI) has signed a 20 year exploration lease on a parcel of the Wyoming dinosaur site, calling on the help of UK associates from the University of Manchester and London’s Natural History Museum (NHM) to assist with the excavations. BBC science correspondent Jonathan Amos was invited to the top secret location to take part in what is arguably the country’s biggest dino dig in decades. There's now good evidence that micro-plastics are present in our oceans and are accumulating in our food chains, but surely they aren’t present in the last pristine environment on Earth? Melanie Bergmann and her team based in Germany compared snow samples from two dozen locations, ranging from the Arctic ice floes and the Norwegian archipelago Svalbard to the north of Germany. Surprisingly, they found 10,000 plastic particles per litre in Arctic snow. But how is the plastic getting there? Melanie provides insight into her ground breaking research unearthing how micro-plastics are capable of travelling such great distances. Producer: Fiona Roberts

In the light of the evacuation of the Derbyshire town of Whaley Bridge due to damage to the Todbrook reservoir dam and the threat of a catastrophic collapse, questions inevitably arise as to how ‘future proofed’ UK dams are? This is doubly worrying in light of climate change and the increasing likelihood of extreme weather events. With the average age of UK dams being over 100 years and the UK climate forecast to become wetter and warmer, should we be concerned? Gareth Mitchell speaks to Rachel Pether from the British Dam Society and Craig Goff, Technical Lead, Dams and Reservoirs from HR Wallingford, who explain the science and engineering involved in monitoring and safely managing UK dams in a changing climate. When someone smiles at you, how can you tell whether that smile is genuine or fake and why would you want to know? According to Professor of visual computing at the University of Bradford, Hassan Ugail, it’s all in the eyes! Humans are notoriously bad at picking up fake smiles, because we tend to focus our vision on the upturned corners of the mouth. Focus on specific movement of the eyes and the dynamic progression of a smile, however, and that’s when a genuine smile is evident. Hassan explains how computers are over 90% successful at being able to detect fake smiles, and examines the purposes to which this facial recognition technology may be applied in our daily lives. Inside Science listener, Thomas from New Zealand, has noticed the sudden surge in nations encouraging mass tree planting and reforestation. But how much of a difference is it all making? Professor of Agriculture, policy and development at the University of Reading Dr Martin Lukac discusses the impacts of, the soot and ash from the recent forest fires in Siberia, deforestation and even makes an educated guess at much forest you would have to plant to counteract the CO2 emissions emitted after using your family car for the year.

James Lovelock is one of the most influential thinkers on the environment of the last half century. His grand theory of planet Earth - Gaia, which is the idea that from the bottom of the Earth's crust to the upper reaches of the atmosphere, Earth is one giant inter-connected and self-regulating system, has had an impact way beyond the world of science. As Lovelock celebrates his hundredth birthday (he was born on 26th July 1919) he is still writing books and thinking about science. Science writer Gaia Vince spoke to him about his work and how he came to his famous but controversial theory. Most hydrothermal vents are in deep water far from land, making them incredibly inaccessible to divers. But in a fjord known locally as Eyjafjörður, off the coast of Iceland, is the hydrothermal vent Strytan. It's close enough that it can be accessed by scuba divers, and the algae and animals living in the hot chemical-laden plumes can be sampled. Geoff Marsh heads out with a team of scientists from the Natural History Museum in London and the University of Southampton to collect creatures living both in the hot vent water and in the icy cold fjord. The idea is to sample the genes to see what adaptations to temperature are evolving. We are hearing more and more about antibiotic resistance. Overuse of antibiotics has led to more and more bacteria evolving and adapting ways to survive antimicrobial treatments. But did you know that the genes coding for this resistance can also float freely in water and on surfaces in the environment? A couple of recent studies have been sampling freshwater bodies and commonly touched surfaces (like handrails and toilet seats) in and around London and the amount of antibiotic resistance genes (either freely floating or in bacteria) is quite alarming. Environmental engineer at UCL, Professor Lena Ciric, explains to Marnie Chesterton what this means and whether we should be concerned. Producer: Fiona Roberts

Dr Adam Rutherford uncovers the worrying number of false positive results that the DNA sequencing technologies used by 'direct to consumer' genetic test kits are producing. Many of these tests offer analysis on your ancestry, but some also offer to check you out for the likelihood of you being at risk of some genetic diseases like cystic fibrosis or certain types of breast cancer. The tests look for variants in your genome, little changes in your DNA that alter the risk of developing a number of genetic diseases. The trouble is the rarer the variant, the more likely it is to be disease-causing. But the rarer the variant, the more likely the simple genetic tests are to get it wrong. And with more and more people sending off their raw genetic data to third-party websites for analysis and annotation, the risk of a false positive result increases to up to 80%. It's a small number of people affected, but a serious one if you're told out of the blue that you are at extreme risk of a serious disease. The advice is to keep an eye on family disease traits and if you are worried, go and see your doctor and get a proper diagnostic test. Deep sea pelagic sharks, like the great white, silky, tiger, porbeagle and blue are much more vulnerable than their scary reputation suggests. In fact, many shark species are in decline as a result of industrial fishing rapidly encroaching upon their territories, and an increased value of the sharks themselves. The oceans are big and sharks range far and wide, so understanding these movements is not easy. Professor David Sims, from the Marine Biological Association of the UK and the National Oceanography Centre in Southampton, is part of a huge international consortium of marine biologists who have been tracking 11 species of shark all over the high seas using satellite technology. We’ve been fishing for more than 40,000 years, but our exploitation of the seas got serious in the last 50 years. In nature, sex can be quite fluid, and in some species, sex changes are just a normal part of every day life. Especially in fish. This type of behaviour is called sequential hermaphroditism, and is common in fish. It's been known about for years, but the underlying genetic mechanisms are mysterious, which is strange for such a radical transformation. In the Blueheaded wrasse, when a dominant male is lost from the shoal, the largest female will immediately begin transforming into a male. Neil Gemmell from the University of Otago in New Zealand has lead a study which for the first time has uncovered the genetics of how the sex change happens. Producer: Fiona Roberts

Code-breaker and father of computer science, Alan Turing has been chosen to celebrate the field of science on the new £50 note. Adam Rutherford asks Chief Cashier at the Bank of England, Sarah Johns how and why he was selected and he asks Sue Black, Professor of Computer Science and Technology Evangelist at Durham University, who campaigned to save Bletchley Park, what this accolade means. In 1969, while millions watched the Apollo 11 moon landing on the television, BBC radio was providing scientific and engineering commentary throughout the day. One young scientist brought in to help interpret the lunar landscape was Lionel Wilson, at the time he had just finished his PhD on the mechanics of the Moon's surface. But after seeing evidence of ancient lava fields in the pictures beamed back to Earth, he changed the course of his career and spent the next 50 years studying volcanology on Earth and in space. 25 years ago, the planet Jupiter was peppered with over 20 cometary impacts, this had never been seen before. The comet was Shoemaker Levy 9, which had already broken into icy pieces. Its fiery death had been foretold a year earlier when calculations showed its orbit was due to cross Jupiter's. As D-day approached, July 16 1994, experts wondered whether there would be fireworks, or a fizzle, they weren't disappointed. Producer - Fiona Roberts

A new study shows that 210,000-year-old skull found in Greece is the earliest evidence for modern humans in Eurasia. A second skull found in the same site is found to be a Neanderthal from 170,000 years ago. These findings suggest that modern humans left Africa earlier and reached further than previously thought. Analysing moon rocks The Apollo missions were scientific explorations, bringing back hundreds of kilograms of moon rock to help us understand the formation of the Moon, the Earth and life itself. We are still studying the rocks that were bought back from between 1969 and 1972. Roland Pease went to the Diamond Light Source Syncotron in Oxfordshire, where scientists are still studying these moon rocks. Viruses lurking in our genomes When it comes to our genomes, there is no such thing as 100% human. Our genetic code is a patchwork of DNA that we have picked up or lost along the way. 8% of our DNA comes from viruses. So what does this mean? Much of the viral DNA is thought to have been involved in forming our immune systems, fighting against pathogenic viruses. But it's not all good news, new work suggests that these human endogenous retroviruses or HERVs might also be the missing causative link in major 'unsolved' neurological diseases such as multiple sclerosis [MS], amyotrophic lateral sclerosis, or Lou Gehrig's disease [ALS] and schizophrenia [SCZ].

The 2019 Royal Society Summer Science exhibition in London is free to enter and continues until Sunday 7th July. BBC Inside Science this week comes from the Society’s HQ in central London. BepiColombo and the X-rays from Mercury Prof Emma Bunce, has been part of the team that last year launched an x-ray telescope on a space probe to Mercury. It will be a long journey, not arriving until 2025. As Emma describes, the MIXS instrument, designed and built in the UK, will analyze the x-rays emitted by the different chemicals on the planet’s surface, and so build a map of the abundancies of different atoms across the terrifyingly hostile world. This is only possible because of the strength of the x-rays coming from the sun that strike the atoms on the surface, eliciting a distinctive signature re-emitted back into space. Capuchin Monkeys and their Tools Tomos Proffitt and colleagues announced in a recent paper in the journal Nature Ecology and Evolution their study of archaeological evidence of Brazil’s capuchin monkeys using stones and anvils to smash cashew nuts for at least the last 3000 years. It is not the oldest evidence of non-human primate tool use but it is the oldest for monkeys, and suggests tantalisingly that tool use may have emerged in hominin species independently and on numerous occasions. Molecular Music Chemistry and music pupils at Ilkley Grammar School in the UK have been working together with The University of Bradford to create music specific to different molecules. As A-Level students Amelia Milner and Matthew Hodson describe to Adam, they took the distinctive frequencies of the bonds in certain molecules found in nature and transposed them onto the chromatic musical scale. Then the musicians composed pieces using only that set of notes that evoked some of the properties of the molecules. AI Drivers and Machine Learning Genovefa Kefalidou shows Adam a self-driving car circling a track at the exhibition. The technology to identify and track different objects is getting better, and machine learning algorithms can map human actions onto different scenarios to find appropriate responses, but is society ready to trust and accept the benefits they might bring?

On the day that the UK government launches a year long “food-to-Fork” review of food production in the UK, we present a food themed special edition. Global Food Security Maia Elliot is an analyst and writer for Global Food Security, who recently held a competition for young food researchers to present their work in a compelling way in less than 3 minutes. Maia and the winner, Claire Kanja of Rothamstead Research discuss with Adam the broader issues “Food Security” seeks to address, and also how best to communicate often esoteric specialized interest to a broader audience that includes food-consuming tax-payers. A Threat to Wheat Claire’s work is looking into a threat to world wheat harvests known as Fusarium Head (or Ear) Blight. She is trying to categorize the proteins that the fungus uses firstly to evade Wheat’s defences, and then to kill the plant cells for its own food. Food Freshness Sensor Meanwhile, at Imperial College, Hannah Fisher reports on new work to make cheap-as-chips gas sensitive food labels that could detect levels of gases inside a food packet that indicate it is gone off or decayed. You could even read them with the NFC chip in most smartphones. The Origins and Adaptations of the European Potato Talking of chips, published this week is a genetic history of the cultivated European potato. Using DNA from museum specimens going back centuries, the authors describe a very complicated to-and-froing between continents that enables modern varieties to avoid certain blights and even to form decent sized potatoes when growing in different day-lengths. Sandy Knapp of the Natural History Museum in London was one of the authors. Presenter: Adam Rutherford Producer: Alex Mansfield

Rinderpest – Sequence and Destroy Last week the UK’s Pirbright Institute announced that it had destroyed its remaining stocks of the deadly cattle virus Rinderpest. This repository was one of the biggest remaining stores of it since it was announced in 2011 that vaccines had eradicated it in the wild. Dr Michael Baron, amongst others, has been arguing for years that because we can now obtain a full sequence of such viruses, we no longer need to run the risk of such scientific samples ever being released, through accident or malice. As such, for Pirbright at least, the rinderpest virus that once killed millions of cattle and starved similar numbers of humans now only exists as a digital memory. Oi, You Singin' at My Bird? The delightful song of the European Robin is actually a fierce territorial warning between males that functions to avoid costly mismatched conflict. In fact, the complexity of the song seems to represent the fitness of the singer. Gareth Arnott of Queen’s University in Belfast talks about his investigation into whether noise – including anthropogenic noise interferes with this life-or-death conversation. It sounds like it does. Science as Entertainment All this week and next BBC2 is hosting a new programme called The Family Brain Games. The games are designed not to test merely general knowledge or conventional measures of IQ, but rather a functional, communicative sort of intelligence that competing families display amongst themselves as a team. But can this sort of nuanced science be properly communicated on TV? Host Dara Ó Briain and neuroscientist Prof Sophie Scott discuss the ins and outs of making science entertaining. Presenter: Adam Rutherford Producer: Alex Mansfield

Net-Zero Carbon Target The UK is set to become the first member of the G7 industrialised nations group to legislate for net-zero emissions after Theresa May’s announcement this week. The proposed legislation would commit the UK’s greenhouse gas emissions to ‘net-zero’ by 2050, which would mean that after reducing emissions as much as possible, any remaining emissions would be offset through schemes such as planting trees or investing in renewable energy infrastructure. Dr Jo House, from the department of Geography at Bristol University, has spent time advising the government on previous carbon budgets and was there in the build-up to the signing of the Paris Agreement in 2016. She talks to Gareth Mitchell about the proposal, what it means for the UK’s climate future and how realistic she thinks the targets are. Science Policy Under Thatcher 30 years ago a new Prime Minister, Margaret Thatcher, told her officials - in a break from the norm - that she would keep a personal eye on science policy in her government. By 1987, the relationship between government, university research and industrial research would be changed utterly. Prof Jon Agar has been scouring The National Archives and a wealth of hitherto private communications that shed light on how her approach to science policy formed. His new book is out this week and he discusses the events with Prof Dame Wendy Hall, a young scientist in the 80s but now fresh to the programme from hearing announcements at the London Technology Week regarding large investment and an industrial strategy towards Artificial Intelligence and Machine Learning. Screen Time Measures If you are using evidence to inform your policy, you need to make sure that evidence is as robust as you think it is. David Ellis of Lancaster University tells Gareth about his team’s recent work to evaluate a certain type of self-reporting, particularly involving studies into our well-being with regards to technology use. How much time do you spend with your device? Your answer might not be completely aligned with reality, as revealed by actual screen-time data. Unfortunately, many of the headline-grabbing papers we read regarding health and screen time are based on self-reporting questionnaires, which David suggests might require more scepticism. Presenter: Gareth Mitchell Producer: Alex Mansfield

Some people have a genetic mutation in a gene called CCR5 that seems to bestow immunity to a form of HIV. This is the mutation which controversial Chinese scientist Jianqui He tried to bestow upon two baby girls last year when he edited the genes in embryos and then implanted them in a mother. A paper in the journal Nature Medicine this week uses data from the UK Biobank to look at the long term health patterns associated with this gene variant. It suggests that whilst the HIV-1 immunity may be considered a positive, having two copies of the gene also comes with a cost. It seems that it may also lower our immunity to other diseases and shows in the database as a 21% increase in mortality overall. Author Rasmus Nielsen talks about how important this gene is to evolutionary biologists trying to find signs of natural selection in humans. Adam discusses the ethical implications of the research with Dr Helen O’Neill. The Surrey Earthquake Swarm Over the last year several small earthquakes have been detected in one part of Surrey. Many have surmised that these may be caused by oil drilling taking place nearby, but it might be simpler than that. So the British Geological Survey has been monitoring the region. Roland Pease joined Imperial College seismologist Steven Hicks out in the countryside inspecting his detectors to find out more. Mama’s Last Hug Frans de Waal, one of the world’s leading primatologists talks to Adam about his latest book, and the difficulties we as human observers have with studying emotion in animals. Prof de Waal coins a neologism ‘anthropodenialism’ to describe the belief that emotions in animals are incommensurable with human experience. He thinks most mammals, and certainly primates, experience pretty much the same emotions as we do, for similar reasons. Feelings, however, are a different matter. Producer: Alex Mansfield

Adam Rutherford and guests at the Hay Festival discuss how maths underwrites all branches of science, and is at the foundation of the modern world. His guests are the following. Professor Steve Strogatz, of Cornell University, the author of a new book on calculus, Infinite Powers. He’s worked on all kinds of problems including some biological ones such as the shape of DNA, how fireflies create light and the grandness of small world theories. Dr Emily Shuckburgh, is a climate change scientist at University of Cambridge, who has a PhD in maths studying fluid dynamics. She is the co-author of the Ladybird book on Climate Change with Prince Charles, Sir Venki Ramakrishnan, is President of the Royal Society, and was originally a physicist, who moved into biology, to study the 3-dimensional shape of one of the most important biological structures, the ribosome, for which he won the Nobel prize winner.

New CFC emissions Researchers say that they have pinpointed the major sources of a mysterious recent rise in a dangerous, ozone-destroying chemical. CFC-11 was primarily used for home insulation but global production was due to be phased out in 2010. But scientists have seen a big slowdown in the rate of depletion over the past six years. This new study published in the Journal Nature says this is mostly being caused by new gas production in eastern provinces of China. Dr Matt Rigby of the University of Bristol and the BBC’s Matt McGrath, who has also been following the trail, tell Gareth about the mystery. Yeast to make cannabinoids In California, where cannabis has become a major cash crop since legalisation there, researchers are trying to evaluate the environmental impacts of large scale agricultural planting. But, as Geoff Marsh reports, other researchers are finding other ways to produce various cannabinoids for potential future sale. Can humble yeast be modified to produce the active substances that some believe to have therapeutic benefits? Hearing aids for cocktail parties One of the most impressive properties of the human auditory system is the way most of us can overhear or eavesdrop on specific voices in an otherwise crowded room. Most hearing aids can’t help with that: they can sometimes filter out noises that are not human voices, but cannot do the very human trick of sorting one voice from a sea of others. Nima Mesgarani from Columbia University reports in the journal Science Advances a proof of principle for a device that might be able to do just that. Firstly, a new algorithm can separate out one voice from another. Then brain waves from the wearer could be used to recognise which of those voices they are trying to hear. Then it’s a simple case of turning that voice up, and lowering the volume of the others, all in nearly real-time. Automatic face recognition So called Neural Network computing techniques are revolutionising our lives. They are able to perform a host of tasks that not so long ago would be the preserve of human brains, and to process huge sets of data and “learn” very quickly. One of the things they are proving exceptional at is face recognition; being able to identify faces in a crowd, or on a street, from a set of images provided by a user. But with great computing power comes great computing responsibility. What are the implications for policing and personal privacy? Gareth discusses these issues with Stephanie Hare. Producer: Alex Mansfield

The Hubble Constant The Hubble constant is the current expansion rate of the universe but it seems to have changed over time. Hiranya Peiris, Professor of Astrophysics from University College London and Adam Riess, Professor of Physics and Astronomy from Johns Hopkins University, are both using different methods to obtain a value for the Hubble constant. But there is a discrepancy in their values. It used to be that the error bars on the two values overlapped, and so cosmologists thought they would converge as the experiments got more precise. But instead, as the error bars have shrunk, the discrepancy is getting more serious, and something must be wrong. They chat to Adam about potential reasons for this difference in calculations and what it could mean for our cosmological model of the universe. Is new physics required to evolve the description of the age of the universe as we know it to be more accurate? A synthetic E. Coli genome Jason Chin and Colleagues at the Laboratory of Molecular Biology in Cambridge have published this week in the Journal Nature their latest work to completely synthesise a new genome of an E. coli bacteria. Not only was the genome designed and manufactured by human means, it was also recoded in a way not used by nature, involving some 18000 edits. In natural DNA, several different codes can do the same job. As Roland Pease reports, the new genome instead uses fewer of these duplicates, demonstrating all sorts of possibilities for future designs of synthetic cells. Von Humboldt Friedrich Wilhelm Heinrich Alexander von Humboldt was a celebrated Prussian geographer, naturalist and explorer. He influenced Darwin and was the first person to describe human-induced climate change, based on his observations from his travels. Yet he has slipped into relative obscurity, at least in the English-speaking world. Andrea Wulf is an acclaimed author who has previously written about Alexander von Humboldt and is now back with another book about the explorer: The Adventures of Alexander von Humboldt. It’s a graphic novel (illustrated by Lillian Melcher) that celebrates the 250th anniversary of Humboldt’s birth and depicts his adventures on his 5 year expedition through South America. Adam Rutherford chats to Andrea about her book, why she chose to make it a graphic novel and how Humboldt’s views on the environment can be interpreted today. Producer: Alex Mansfield

A damning House of Lords' report into the provision of forensic science in England and Wales makes for uncomfortable reading for some but is broadly welcomed by those in the field. Prof. Niamh Nic Daeid, one of many who gave evidence to the Science and Technology Committee, gives her reaction and suggests how a combination of unsatisfactory regulation, profit and austerity pressures in a uniquely commercialised sector, and some surprising gaps in the science knowledge base has lead to a sorry situation. Spring has sprung and it's probably not too late to get the tomato plants in, but should you water them little and often, or more but less often? Madeleine Finlay reports from Wisley, where The Royal Horticultural Society's Janet Manning has set up a new experiment this year to answer that question. Janet is the first Garden Water Scientist at the RHS, and hopes to demonstrate that giving plants less frequent, but more generous, bouts of hydration encourages deeper root growth, building in resilience for those periods when water is harder to come by whilst also allowing gardeners ultimately to use less. Do you have a fabella? Or maybe two fabellae? Michael Berthaume, "Anthroengineer" at Imperial College London tells us about a curiously under-studied bone that some people have in their knees. Present in certain primates and quadruped mammals, but thought to have disappeared from human anatomy, it seems to have made a bit of a comeback in certain populations around the world over the last century or so. Quite why, quite how, and quite what it's for, seems something of a mystery.

In 2018, the International Association of Athletics Federations (IAAF) introduced new eligibility regulations for female athletes with differences in sex development (DSDs). These regulations are based on the contention that women with high levels of endogenous testosterone and androgen sensitivity have a performance advantage over their peers. South African middle distance runner, Mokgadi Caster Semenya, who won two Olympic gold medals in 2012 and 2016, and Athletics South Africa, are contesting the legality of these new regulations. The basis of their objection, at the Court of Arbitration for Sport, is that there is a lack of scientific evidence showing that endogenous testosterone concentrations substantially enhance sports performance. Caster, who is DSD herself, has lost her case and Adam turns to expert in sport, exercise and genomics at Manchester Metropolitan University, Dr. Alun Williams to explain the implications. Less than a decade ago, an entirely new branch of the ancient human tree was discovered. These new hominins were named the Denisovans, after the Denisova cave in the Altai Mountains in Siberia where fragments of finger bone and teeth were discovered, and genetic sequencing of a finger bone revealed that they were a new hominin group, an extinct sister group to Neanderthals. This exciting find contained a tantalising puzzle. Traces of Denisovan DNA are found in modern-day population groups like Sherpas, Tibetans and some other neighbouring populations and this includes genetic variants which help them to survive at high altitudes where the oxygen levels are low. The original Denisovan cave is only around 700 metres, so why would such an adaptation be necessary at these altitudes? This week a new paper in Nature slots a big piece into the puzzle. Teams from the Institute of Tibetan Plateau Research and the Max Planck Institute for Evolutionary Biology have found another Denisovan fossil – this time a mandible, a lower jawbone, still containing teeth – from the vast Tibetan plateau in China. At 2.3 Km above sea level, it’s very high and the air is thin, and 160,000 years ago, which is when the fossil has been dated to, it would have been a very challenging place to live indeed. In fact this jawbone is the earliest known hominin fossil found on this enormous plateau. Adam calls in Professor Fred Spoor, from the Centre for Human Evolution Research at the Natural History Museum in London, to examine the facts and to see if we can work out how far and wide these hominins travelled.

Patients who suffer neurological impairments preventing them from speaking potentially face a severely limited existence. Being able to express yourself in real time is a large part of our identity. In the journal Nature this week, scientists from the University of California, San Francisco, report a new technique for synthesising speech based on measurements of neural signals taken from the brain. Author Dr Gopala Anumanchipalli tells Adam about how this proof of principle could one day form the basis for a speech prosthesis for patients who have lost the ability to converse. Around the world this weekend (April 26th-29th 2019) people are being encouraged to participate in the City Nature Challenge, a global effort to catalogue urban wildlife using a free mobile app. Reporter Geoff Marsh travelled to the California Academy of Sciences, home of the initiative, to meet those behind it and how we might all take part. The third act in our drama is a chat with journalist and writer Will Storr about his new book - the Science of Storytelling - which explores the structure of stories with relation to our evolution and brain structure. Primeval instincts of expectation, subversion and causation intertwine with camp-fire sagas from the beginning of conversation. What can this science of storytelling contribute to the art of telling stories about science? A ripping yarn indeed. Producer: Alex Mansfield

The horror of the blazing Notre-Dame cathedral in Paris has been slightly quenched by the fact that so much of the French landmark has been saved. But what was it about the structure of the roof, with some the beams dating from the 13th century, that meant it burned like a well-stacked bonfire? Guillermo Rein is Professor of Fire Science at Imperial College London , and he explains to Adam Rutherford how wood burns and how it was the intricate mixture of large and small beams, and very poor fire protection measures that made the iconic roof, so vulnerable. An experiment to see whether isolated dead pig brains could be preserved at the cellular level in order to study post mortem brains, had a surprising outcome. The BrainEx technology of perfusing the brains with chemicals that should have just halted the rapid degradation of cellular structure in the brain, that occurs soon after death, actually caused them to start firing neurons, reacting to drugs and generally behaving as if they were alive. Although, it has to be stressed, there was no whole-brain connectivity or consciousness achieved, it does raise ethical questions about death, if this method was to be developed for use in humans. Bioethicist at Kings College London, Silvia Camporesi explores the facts that reveal that death is a process rather than a single event and what this might mean for patients that are diagnosed as brain dead. Where is the Martian methane? This is the question Mannish Patel at the Open University has been left pondering after the ExoMars Trace Gas Orbiter came up empty handed in detecting the gas on Mars. Methane could be a signature of past of present life on the Red Planet, it's been measured by NASA's Curiosity rover and by telescopes on Earth, but the far more sensitive and specialised TGO has so far failed to detect the gas. It could be because methane levels in the thin Martian atmosphere is a seasonal event, we'll just have to ait for an entire Martian year of surveys to be able to solve this mystery. Our faces are incredibly important in our lives, we feed through them, they are the conduit for our sensory interaction with the universe, via smell, hearing and vision; we speak, and we convey the subtlest emotions with a raised eyebrow, a wry smile, a clenched jaw or eyes wide open. It is the central importance of these features that has meant we’ve been intensively studying the evolution of the face for decades, to work out why we look the way we do, and how much of our looks reflects adaptations that enhanced our survival, and how much is just down to quirks of evolution. Anatomist, Paul O’Higgins from York University is interested in how all that has influenced our faces. Producer: Fiona Roberts

"We have now seen the unseeable" according to scientists who are part of the Event Horizon Telescope group. The international team has released a picture of the first black hole. Data gathered from an array of over 8 radio telescopes has been crunched to create a picture of the super-hot plasma surrounding the black hole M87. It shows extremely excited photons on the brink of being swallowed up by the supermassive black hole, 500 million trillion km away. Marnie Chesterton, asks UCL cosmologist Andrew Pontzen what the glowing doughnut-shaped image can tell us about the laws of gravity and relativity. A new species of hominin has been discovered in caves at the northernmost tip of the Philippines, on the island of Luzon. The discoverers have called this creature Homo luzonensis, and it's thought to be 50,000 years or older. The teeth, hand and foot bones suggest it could have been a mixture of early modern humans - Homo sapiens- and older ancestors like the Australopithecines. Cambridge University's Leverhulme Professor of Human Evolution, Robert Foley suggests some caution with calling this a new species, and explains how populations of hominins isolated on islands could evolve to be different by a mechanism called genetic drift. The world is facing an antimicrobial crisis. The global fight against infections is looking worrying as more and more strains of bacteria emerge which are resistant to our stocks of antibiotics. Marnie visits to Tblisi, in Georgia to meet scientists who are looking at a different way to fight infections, collecting and using the microscopic phage viruses which infect the bacteria which infect us. Another way to try and beat antibiotic resistance was the focus for Susan Rosenberg at the Baylor College of Medicine in Houston Texas, when she thought it might be clever to try and stop microbes evolving resistance to antibiotics . She discovered that when microbial cells are stressed, a number of them actually start to mutate at a greater rate. This means they stand a greater chance of mutating into a form that has some resistance to our drugs. But by learning about the finer details of this mechanism, and finding a drug that can halt it. She and her team hope to skew the evolutionary arms race between microbes and antibiotics and our immune systems in our favour. Producer: Fiona Roberts

About 66 million years ago an asteroid at least 6 miles wide crashed into the Earth, in the shallow sea that is now the Yucatan Peninsular in Mexico. It gouged the Chicxulub crater 18 miles deep; threw 25 trillion tonnes of debris into the atmosphere, much of which was hotter than the Sun, created huge seismic waves and massive tsunamis churning the Gulf of Mexico, tearing up coastlines and peeling up 100’s of metres of rock. 75% of the Earth’s forest burned. Debris was thrown out across the Solar System and North America was showered by a fan of glassy molten rock droplets. This geological event marked the end of the Cretaceous period and the start of the Palaeogene. Most people accept that this massive event caused the last great extinction, the end of the dinosaurs and a period of intense cold. Many fossil finds back this theory up. But very little fossil evidence showing the impact of the actual event has been found. Until now. Hundreds of miles from Chicxulub in a fossil site called Tanis, in North Dakota, part of the vast Hell Creek formation, is a fossil find that depicts the turmoil 10's of minutes after the asteroid hit. Marine and freshwater fish are found tangled together with these glassy droplets crammed in their gills, Charred trees are mixed up with hundreds of mangled animal bones, amber perfectly preserving drops of what was molten Earth. It's got palaeontologists including Professor Phil Manning at Manchester University very excited. The gravitational wave detectors LIGO and VIRGO have been recently upgraded and made more sensitive to the miniscule signals that denote ripples in gravity - gravitational waves. Professor Sheila Rowan of the University of Glasgow explains to Gareth Mitchell that she hopes that with this third run of the detectors, they will be finding not just one or two signals that provide evidence of massive events in our universe, but hundreds, maybe even thousands. In the quest to understand how corals are affected by rising sea temperatures we need to understand the symbiotic relationship they have with dinoflagellates, the single-celled algae that live in, and use photosynthesis to make food for the coral. When coral gets too hot and undergoes 'bleaching', this is the algae leaving the coral. Yixian Zheng at the Carnegie Institution of Washington takes Roland Pease on a tour of her coral tanks and explains that she's hunting for a model coral organism to study this process at the genetic and molecular level. A crime has been committed in the studio. Gareth's tea has been drunk and his biscuits have been nibbled. Luckily evidence was left at the scene of the crime - a shoeprint with distinctive wear patterns. One quick phone call and the director of the Leverhulme Research Centre for Forensic Science at the University of Dundee, Professor Niamh Nic Daeid is on the case. She's asking the public to help build up a database of footwear prints. The project is the largest ever study into the variation in footwear marks made by the same shoes across different surfaces and activities so that the variation observed can be used to explore links between the shoe and the mark it makes. In order to do this, she's asking thousands of individuals to take part in a large-scale citizen science project by taking pictures of their footwear and the marks they make. This will help the Dundee team build a substantial database for use in their research to aid the scientific validation of footwear marks as evidence for use in the criminal justice system.

One of the longest running insect pollinator surveys in the world, shows that a few generalist pollinators are on the increase, whereas specialist insects are declining. Using data collected by volunteers across Great Britain to map the spatial loss of pollinator insect species, the study by the CEH (Centre for Ecology and Hydrology) measured 353 wild bee and hoverfly species across the country. The results showed that on average, each 1km2 survey patch lost an average of 11 species from 1980-2013. CEH's Professor Helen Roy and Dr Claire Carvell explain to Marnie Chesterton how volunteers can take part in the next survey. Want to know where a whale has been? Just ask the barnacles on its head! Barnacles hitchhike on whales, and they’ve been doing this for millions of years. When barnacles grow they add to their carbonate shells using compounds from their surroundings. As the whales migrate, the barnacles take up compounds from the different oceanic locations. A bit like filling in a travel diary, or collecting passport stamps. If you can decipher the chemical code laid down in the barnacle shells, you can work out where the whale has been on its oceanic migrations. This is what researcher Larry Taylor, at University of California Berkeley, has been doing and he says that the information can even be found in fossilised whales (and barnacles.) The patterns signals in our brain make when we are falling asleep are quite hard to study. But thanks to a few people who manage to fall asleep in an FMRi scanner, we now know there are multiple stages of sleep. Professor Morton Kringlebach, a professor of neuroscience at the University of Oxford likens the pattern of brain activity, as it enters the various sleep stages, to the choreography of a dance. His friend, Dr. Milton Mermikides at the University of Surrey, goes one further. As a composer and academic expert in jazz, he thought the pattern of brain activity was like chord changes in jazz music. So he put the sleepy brain to music. Marnie listens to the soporific tones and asks if people with disordered sleep, such as insomnia or restless leg syndrome would make different music? Producer: Fiona Roberts

30 years ago Tim Berners-Lee invented the World Wide Web as a way to let physicists share their papers and data on a distributed network. It's changed a lot since then and not all for the better. Dominant technology companies monopolise our data and many, including Berners-Lee are worried about the growth of state sponsored hacking, misinformation and scamming. One solution is to re-decentralise the web, giving us more control of our information and what is done with it, but at what cost? Founder and director of Redecentralize.org, Irina Bolychevsky and technology guru Bill Thompson discuss the future. BBC Space Correspondent Jonathan Amos has news on some space rocks this week. Ultima and Thule, make up a bi-lobe comet out in the far reaches of the Solar System in the Kuiper Belt. Ultima-Thule was visited by the New Horizons mission in January. More data is being analysed and giving scientists insight into how these two planetary building blocks collided and merged and also on how it got its strange flattened shape. Another rock seems to be a rubble pile. The asteroid Ryugu is currently hosting the Japanese Space Agency's Hayabusa 2 spacecraft and landers. Jonathan explains to Gareth what stage the missions' audacious sample collect and return is now at. And there's a shock discovery by spacecraft OSIRIS-REx from asteroid Bennu. The NASA spacecraft analysing the asteroid has observed it shooting out plumes of dust that surround it in a dusty haze. It's a phenomenon never seen in an asteroid before. Back down on Earth and under the surface of the earth are the earthworms. As any savvy gardener will know, earthworms make a big difference to the health of soil and plants. What isn’t as well understood is how changes to the soil - like climate change and the intensification of agricultural practices - have impacted on the all-important worm population. In fact, scientists don’t even know what’s down there, wriggling underneath the surface. To find out, farmers recently undertook to the first worm survey in the UK. Finding that 42% of fields had very few or completely lacked key types of earthworm, the results suggest that over-cultivation has led to poor soil health in significant amounts of farmland.

When the news broke last December that Chinese biophysicist He Jiankui had successfully edited the genomes of twin girls using the technique known as CRISPR-Cas9, scientists and the public were rightly outraged that such a procedure had taken place. Jiankui is currently being investigated by Chinese authorities for breaking legal and ethical guidelines on human genome editing. This week, in the journal Nature, several top scientists have called for a global moratorium on gene editing in the clinic. Which might be surprising, because we thought these rules were already in place. Dr. Helen O’Neill, a Lecturer in Reproductive and Molecular Genetics at UCL explains to Adam Rutherford what the current rules are, and they debate whether we need a ‘voluntary moratorium’. It’s hard to miss the current discussions on sex, gender, and biology. One arena where debates are getting quite heated is sport. In 2016, the International Olympic Committee announced that male-to-female transgender athletes will be allowed to compete in the Tokyo Olympics in 2020, without having gender reassignment surgery. They do have to demonstrate reduced blood testosterone levels (usually achieved through hormone therapy). Female-to-male transgender athletes can compete ‘without restriction’. Gerard Conway, Professor of Reproductive Endocrinology at the Institute for Women’s Health at University College London, joins Adam to help us understand many of the issues concerning testosterone and its putative effect on athletic performance. The festival hog roast has been happening for more than four and a half thousand years. Hundreds of pig bones have been unearthed from henge sites including Durrington Walls near Stonehenge in Wiltshire – and these have helped put together a picture of life in Neolithic Britain, especially when people came together from all over the country, and brought pigs with them for big feasts. Dr. Richard Madgewick at Cardiff University carried out isotopic analysis on the pig bones to work out just how far people travelled with their pigs to attend these social events.

An HIV-1 sufferer, who had developed aggressive cancer, and underwent a revolutionary stem cell transplant, has been declared HIV resistant. It's been 18 months since the 'London patient' underwent a stem cell transplant of donated HIV resistant cells. This has only happened once before, in the case of the ‘Berlin Patient' – who, after two transplants, has now been HIV and cancer free for 10 years. Professor Ravindra Gupta at Cambridge University is careful not to say the work carried out at UCL has ‘cured’ the patient, but it’s very promising. They say they have made the patient’s cells ‘resistant’ to infection by the HIV virus. There are no animals that do not need sleep, yet we're still not sure why we need to sleep. Giorgio Gilestro at Imperial College has been trying to find out more about whether lack of sleep shortens lifespan, by bothering fruit flies and stopping them dropping off. In a carefully designed experiment, he has devised a way of shaking the flies as soon as it looks like they are dropping off. He tells Gareth Mitchell that he's 98% certain the flies were kept awake day after day and discovered that there was no life-shortening effect due to lack of sleep. He cannot rule out the benefit of micro-sleep, but it provides tantalising results which could point us in the direction of finally discovering whether we need those 8 precious hours a night. Eight years ago, on 11th March 2011, three of the nuclear reactors overheated and exploded at the Fukushima nuclear plant in Japan. This was following the tsunami that killed around 19,000 people. The essentials are known – the reactors overheated when the cooling circuits failed. The overheated steam then broke down into hydrogen and oxygen, which then caught fire and blew the reactor vessels apart. But the details aren’t known. And there’s no way of getting inside the reactors to learn them. So instead researchers are doing a forensic analysis of the radioactive debris scattered around the reactor sites – some of it at the Diamond X-ray facility just outside Oxford. Roland Pease was waiting in the experimental area as one grain of Fukushima dust was brought in from safe storage. Concerned about a growing number of spurious scientific claims on products and campaigns against vaccinations and the shape of our planet, climate scientist Ben McNeil decided to do something about it. He has come up with a website where anyone can pose a question for scientists to answer. MetaFact.io is just starting up, but Ben's hope is to put the public in direct contact with the scientists with some, if not all, of the answers.

Efforts to cut emissions of carbon dioxide (CO2) and tackle climate change in many developed economies are beginning to pay off, according to research led by Corinne Le Quere at the Tyndall Centre at the University of East Anglia. The study suggests that policies supporting renewable energy and energy efficiency are helping to reduce emissions in 18 developed economies. The group of countries represents 28% of global emissions, and includes the UK, US, France and Germany. The research team analysed the various reasons behind changes in CO2 emissions in countries where they had declined significantly between 2005 and 2015. They show that the fall in CO2 emissions was mainly due to renewable energy replacing fossil fuels and to decreasing energy use. Methane is many times more potent a greenhouse gas than carbon dioxide. However, it breaks down much more quickly than CO2 and is found at much lower levels in the atmosphere. During much of the 20th century levels of methane, mostly from fossil fuel sources like coal and gas, increased in the atmosphere but, by the beginning of the 21st century, they had stabilised. Then, surprisingly, levels starting rising in 2007. That increase began to accelerate after 2014 and fast growth has continued. Studies suggest these increases are more likely to be mainly biological in origin. However, the exact cause remains unclear. Some researchers believe the spread of intense farming in Africa may be involved, in particular in tropical regions where conditions are becoming warmer and wetter because of climate change. Rising numbers of cattle – as well as wetter and warmer swamps – are producing more and more methane. This idea is now being studied in detail by a consortium led by Professor Euan Nisbet, at Royal Holloway, University of London. Another, more worrying source for the increase in methane could be that it’s not been broken down in the atmosphere as efficiently. Natural chemicals in the atmosphere, which help to break down methane, may be changing because of temperature rises, causing them to lose their ability to deal with the gas. The Francis Crick Institute is a biomedical discovery institute researching the biology underlying human health. This vital research is carried out by some of the best scientists in their field. However, many, many more people are involved behind the scenes. ‘Craft and Graft’ is a new exhibition at the Francis Crick Institute celebrating these ‘unsung heroes’, and opens on 1 March, focusing the spotlight on the technicians, engineers and support staff that are vital in supporting the scientists and their work by ensuring the glassware is washed, the equipment runs smoothly and the cells are all looked after and categorised correctly. Hannah Fisher was granted special access behind the scenes to meet some of the people who inspired the exhibition. Producer: Fiona Roberts

Nasa have called time on the 14 year mission with the Mars Opportunity rover. Curiosity is still there. But what's next for our exploration of the Red planet? Adam asks Senior Strategist in Space Systems at Airbus, Liz Seward and BBC space correspondent, Jonathan Amos. Airbus are working with the European and Russian Space Agencies on the next rover, part of the Exomars mission. This new rover is called the Rosalind Franklin, after the UK scientist and when it hopefully lands in 2021, it'll be drilling down, deep into the surface of Mars to look for evidence of past life. We know that trees help mitigate the effects of greenhouse gases on climate change by sucking up carbon dioxide from the atmosphere. In fact forests are estimated to lock up 2 of every 10 carbon molecules released. But which forests do it best? Tom Pugh at the University of Birmingham has been looking at the age of forests to try and see if this is a factor. It turns out the pristine, ancient tropical forests like the Amazon, although doing a good job, just aren't as good as the younger, regrowth forests of the Boreal and Temperate zones in the northern hemisphere. It's all down to demographics and the balance between new trees and dying trees. We keep hearing that this, or that, species is being threatened by climate change, but often the mechanisms are not that obvious. One particularly intriguing example comes in the form of the Ethiopian bush crow. An intelligent, seemingly adaptable bird, living in what seems like a general, widespread habitat in Southern Ethiopia, eating a wide and varied diet. Yet it's range is restricted to tiny pockets of land in a huge area of, what seems like a similar habitat. Ecologist, Andrew Bladon at Cambridge University thinks he has the answer to what's restricting this bird's range and how is a warming climate pushing this bird to extinction.

A very strongly worded, meta-review paper (looking at 73 historical reports from around the world published over the past 13 years) has just been published looking at the fate of insects around the world. The researchers have collated other people’s research, including the big 27 year study from Germany, that showed 75% loss of insects by weight (biomass). The basic headlines are quite scary: 40% of insect species are declining; 33% are endangered; we’re losing a total mass of 2.5% of insects every year. The reviewers blame habitat loss by conversion to intensive agriculture as the main driver for the declines, plus agro-chemicals, invasive species and climate change adding to the burden. Adam Rutherford speaks to insect expert Professor Adam Hart from the University of Gloucestershire to discuss numbers and consequences. It’s quickly being realised that the composition of microbes in our guts is vital to our health. Scientists working on the gut microbiome have discovered and isolated more than 100 completely new species of bacteria from healthy human intestines. It’s hoped that these new techniques to isolate and grow these novel bugs, will give us insight into how our microbiome keeps us healthy. After covering the story about the Earth’s early core accretion and the clues found in rocks about the early magnetic field, listener Neil Tugwell emailed BBC Inside Science to ask for more information about geomagnetic switching. Are we heading for another flip of the magnetic poles? And what might be the impact on GPS? Adam gets the answers from Dr. Robert Wicks, lecturer in space risk in the UCL Institute for Risk and Disaster Reduction. Producer: Fiona Roberts

In 2016 some scientists suggested that with climate change so much ice in Antarctica could melt that the global sea level could rise up to a metre. There would be an "ice apocalypse". Now another group has refined the models and in a paper published this week has concluded that the rise will be lower. Adam Rutherford and lead author Dr Tamsin Edwards of Kings College London discuss the latest research and how policy makers and the public should react to changing results from ice sheet studies. All race meetings in the UK have been cancelled today following the discovery that three horses have been diagnosed with equine flu, despite having been vaccinated. Expert on equine flu at the University of Nottingham, Dr Janet Daly, talks to Adam about the disease, how the outbreak has come about and the process of making a new vaccine. What if the walls of your house generated their own electricity? It may sound far-fetched, but one team in the chemistry department of King’s College London is trying to do just that. Reporter Hannah Fisher went to visit Dr Leigh Aldous to discover his invention – a brick, which is hoped to be made out of recycled plastic, that can generate its own electricity. While the project is still in its early stages, it is hoped that the brick will be able to be used in off-grid and remote locations, as well as those affected by natural disasters. Scientists have analysed DNA samples from people living on the Iberian Peninsula to determine their genetic heritage. Results revealed near vertical stripes running from the north of the peninsula to the south, indicating that at this fine resolution, Spanish people are more genetically similar from north to south as opposed to east to west. Dr Clare Bycroft of Oxford University chats to Adam more about how this fits with what we know about Spanish history.

Many physical features of Neanderthals might not be for cold climate adaptation as previously thought. They may be for types of locomotion. Which, according to paleo-ecologist, John Stewart at Bournemouth University, makes the long thigh to calf ratios more likely that Neanderthals were adapted to fast, powerful sprints, as part of their hunting and survival. The clues to this lie less in the bones and more in the evidence that Neanderthals lived in wooded areas rather than tundra. Earth’s solid iron inner core, liquid outer core and interactions between the two give us our protective magnetic field and are responsible for the ‘geodynamo’ that drives this, as well as volcanism and Earth’s tectonics. But we don’t yet know when the solid core formed. It’s hard to find paleo-magnetic records from early in Earth’s history. But now a group at Rochester University in New York have discovered magnetic particles from 565 million year old Ediacaran Period rocks in Canada and they say that at the time lots of life was evolving on our planet, the geodynamo was low and wobbly. This leads them to believe the solid core formed two to three times later than previously thought. A typical sneeze will throw out 40,000 tiny droplets loaded with viruses or bacteria, which can hang in the air like a cloud until someone else comes along and inhales some. To a scientist, this suspension is an aerosol, and what goes on inside a tiny droplet can be very different from what happens in a beaker of fluid. But studying those conditions, which can alter whether a germ can survive its aerial journey is hard. Which is why at Bristol University they’ve developed an aerosol trap that can hold droplets mid-air, without contact, with an electric field. Rabbits and hares across Europe have been declining rapidly over the past few decades. There are a number of factors involved (Agricultural intensification, climate change, hunting and a whole host of infectious diseases.) Myxomatosis in rabbits, which has now jumped into hares, is fairly well known by the public, but there are other viral and bacterial diseases that are jumping between the species and the most recent one Rabbit Hemorrhagic Disease Virus 2 (RHDV2) is of particular concern right now. Very little is known about this disease in wild populations. It was seen in hares in Europe a few years back, but it’s now just been identified in the UKs native brown hare population. Biologist Diana Bell at the University of East Anglia wants the public to contact her if they see any hares that look like they’ve died from the disease. Producer - Fiona Roberts

2019 means the opportunity to explore the most distant object yet encountered in our solar system – the brilliantly named Ultima Thule as Nasa’s New Horizons spacecraft hit the headlines this week when it flew past an object 4 billion miles away, took photos and sent them back to earth. The stunning images confirmed that Ultima Thule looks a bit like a snowman, only several miles in length and orbiting somewhere much colder than any earth winter. Inside Science talked to Dr Carly Howett, a member of the New Horizon’s team and deputy principle investigator of the RALPH instrument, which will send back data on Ultima Thule’s form and structure later this year. And For many of us, January is a time to try a bit better. And millions of us decide to give up alcohol. It’s called Dry January. But what does this alcohol break actually achieve? Has anyone scientifically researched the results of a month off the sauce? Marnie Chesterton spoke to liver specialist and senior lecturer at university college London, Dr Gautam Mehta. And because chemists are celebrating the 150th birthday, or rather birth-year, of the Periodic Table we thought BBC Inside Science should as well. The table is that chart on every science classroom wall. It’s a grid of small boxes, each with a symbol that represents a chemical element. And elements are the fundamental substances that make up everything you can see, and quite a few things that you can’t. We spoke to chemist Dr Eric Scerri at UCLA, who has written a book on the history and significance of the Periodic Table while Roland Pease visited the lab of Professor Andrea Sella, who is making a physical representation of the whole table, if he can find all the elements that is.

Claims by a Chinese scientist that he has gene-edited human embryos, transplanted them producing genetically edited twins, who will pass on these changes to their offspring, has the scientific community outraged. The work, which was carried out in secret, has not been officially published or peer reviewed, but if the claims are to be taken seriously, this work severely flaunts international ethical guidelines at many levels. BBC Health and Science Correspondent James Gallagher explains the story so far. Little is known about the placenta and how it works, despite it being absolutely essential for supporting the baby as it grows inside the mother. When it doesn’t function properly, it can result in serious problems, from pre-eclampsia to miscarriage, with immediate and lifelong consequences for both mother and child. Our knowledge of this important organ is very limited because of a lack of good experimental models. Animals are too dissimilar to humans to provide a good model of placental development and implantation, and stem cell studies have largely proved unsuccessful. But one group of University Cambridge researchers have now created ‘mini-proto placentas’ – a cellular model, growing long-term, in 3D of the early stages of the placenta – that could provide a ‘window’ into early pregnancy and help transform our understanding of reproductive disorders. The Woodland Trust want you to tell them when you notice a tree, you regularly see, loses all of its leaves. Its part of their long term phonological study, Nature's Calendar .

The Government's strategy to eradicate TB in cattle is a contentious topic. The disease is extremely complicated and lots of people have different ideas on how to manage it. Professor of Zoonotic and Emerging Disease at the University of Nottingham, Malcolm Bennett, helps Adam Rutherford understand just how complex the TB bacterium is, how difficult it is to test for infection and why the vaccine BCG does and doesn't work and answers listener's question of why don't we vaccinate cows? Citizen scientists and their smartphones are being recruited to test the supermassive particle theory of dark matter and dark energy. The CREDO (Cosmic-Ray Extremely Distributed Observatory) project utilises smartphone cameras to take 'dark photos' and hopefully capture a particle collision that could be from the cascaded decay of these early universe massive particles or WIMPS. Metrologists from across the world have just voted to update the metric system. With the redefinition of the kilogram, alongside the units for temperature, electrical current and amount of substance. For the first time, we now have a measurement system defined by fundamental constants of the universe and not physical artefacts made by humans. Reporter Henry Bennie travelled with the UK's kilogram to Paris for the vote. NASA's Mars InSight mission lander is expected to touch down on the red planet on Monday. BBC Science Correspondent, Jonathan Amos, explains to Adam just how this stationary science lab will explore Martian geology looking for signs that life could have existed at one time on our neighbour.

The Bovine TB Strategy Review has just been released. It contains a review of the science and offers advice and guidance to Government ministers on how to eradicate this costly and hard to manage disease in cattle. Controversially it does not include the results from the on going badger culling trials in the West of England and it states that the majority of disease transmission is from cow to cow. But it addresses the efficacy of skin TB tests and repeatedly states that the long-term aim is to end culling badgers and moving to vaccination or other non lethal methods to control the disease reservoir in wildlife. Professor Rosie Woodroffe at the Institute of Zoology, who ran the Randomised Badger Culling Trials in 2007, thinks the report is mostly a good thing. She praises the advice to find alternatives to killing British wildlife, but explains to Adam Rutherford that trialling vaccinations for badgers after culling could be problematic. Monitoring the health of estuarine and coastal water ecosystems usually relies on the expensive and time-consuming practice of catching fish to get a view on the health of entire ecosystem. New methods are starting to be used called Environmental DNA sampling, using DNA barcoding techniques. As everything sheds fragments of DNA into the environment, by sampling water or sediment, you can use High Throughput DNA analysis, using special probes to pull out and identify the species you want. It’s a lot quicker and cheaper, but you still have to deal with problems of collection, filtration and contamination. But Professor of Conservation Genetics, Stefano Mariani at the University of Salford, has found an even better way. He's recruited the European brown Shrimp, which eat everything, are found everywhere and can do all the filtering and storing of the DNA for him. All Stefano has to do is catch the shrimp and analyse their stomach contents to get a picture of what is in the environment. PhD student at Sheffield University, Rory Cooper explains to Adam how mathematical patterns that Alan Turing worked on late in his career are found in abundance in the natural world. The genetic mechanisms of switching on cellular processes that lead to feather or hair emergence have now been found in the formation of shark scales. The pattern relies on genes to switch on a function, such as feathering, but diffuse out to surrounding cells and switch the function off, leading to a uniform, spaced out pattern. As shark species split off from other vertebrates around 420 million years ago, it therefore proves that Turing’s pattern is recycled through other vertebrates. Producer: Fiona Roberts

What could be the oldest figurative cave paintings in the world have been found in a cave complex in remote Borneo. A reddish orange depiction of an animal that could be a Banteng (wild cattle found in the region) is at least 40,000 years old. Humans are now the greatest force in shaping the surface of the Earth. We now move more than 24 times as much rock, rubble and sediment than all the world’s rivers. Dr Anthony Cooper of the British Geological Society has been weighing this anthropogenic global force. Closer to home, Adam Rutherford speaks to Professor Colin Waters at the University of Leicester, about the weight of human-created rubble he’s found under the City of London. When the new polymer £50 note is introduced in around a year’s time, it’ll have a scientist on the reverse. Industrialist Matthew Boulton and engineer James Watt will step aside for a British scientist nominated by the public. Sarah John, Chief Cashier at the Bank of England, explains the rules to Adam and science experts, Emily Grossman and Alice Bell debate the merits of some of the more popular front runners.

Potholes are one of the biggest frustrations to any road-user, but why do they keep occurring? Following Philip Hammond’s announcement of £420 million for councils to tackle potholes, Malcolm Simms, Director of the Mineral Products Association’s Asphalt & Pavement group, explains how potholes form and why they continue to occur. Alvaro Hernandez of Nottingham University chats to Marnie about new solutions he is investigating to improve our roads and reduce the number of potholes. Roland Pease meets John Able and Professor Simon Potts, to discuss the value of ‘big data’ – in this case, for honeybees. Using a ‘buzz box’ to detect conditions inside and out of the beehive, this data can be transmitted to the cloud and used to keep track of beehive health. This is termed the ‘internet of hives’ and provides a huge amount of high quality data to discover the key indicators of beehive health. Back in the 1980s, the world discovered that CFCs were destroying the ozone layer, which protects the earth, and us, from being fried by the sun’s rays. The 1987 Montreal Protocol banned the use of CFCs, and as we stopped emitting them, the ozone layer started to recover. But there are other gases like carbon tetrachloride that destroy the ozone layer and are also restricted. But Dr Matt Rigby, an atmospheric chemist from Bristol University, has been discovering that there are still sources of carbon tetrachloride. Testing for illicit drugs usually needs a blood or urine sample, but now it can be done from a sweaty fingerprint. And not only on a living suspect, but on a corpse. Adam Rutherford speaks to the developer of this smart chemistry , University of East Anglia’s David Russell.

How might Brexit affect UK Science? Why is feeding a 'last resort' antibiotic to farm animals not a good idea? Why is space probe Bepicolombo going to Mercury? Adam Rutherford is your host. This week, leading British and European scientists wrote to the British Prime Minister and European Commission President. They expressed their concerns about the potential impact if there is a no-deal departure by the UK from the European Union. We hear from one of the signatories Professor Venki Ramakrishnan, President of the Royal Society and from UK Science Minister Sam Gyimah. Roland Pease reports on the use of the medically valuable last-resort antibiotic, colistin, as a growth promoting substance in agricultural livestock feed in India. He speaks to infectious disease consultant Abdul Ghafur in Chennai, India and microbiologist Tim Walsh at Cardiff University. The space probe Bepicolombo has begun its 7 year voyage to the planet Mercury. Suzie Imber of the University of Leicester and David Rothery of the Open University tell Adam why the journey will take so long and why Mercury is such an intriguing planet, worthy of exploration by this new probe.

How far back can we trace the ancestry of dogs? For just how long have they been following us around? The answer is for a very long time - long before humans settled down and developed societies. Scientists in France have been looking at ancient dog DNA to try and work out whether people tamed and domesticated local dogs as they migrated across the planet, or brought dogs with them. The answer tells us much about the relationship - or rather lack of it, between early farmers and the hunter gathers they replaced throughout Europe. And how many Bosons can you fit in a rocket? As they are rather small particles the answer will be quite a lot, but a team from Germany has succeeded in making a form of mater known as the Bose Einstein Condensate in a small rocket which they launched into the Earth’s upper atmosphere. Potentially the success of their experiment could lead to new ways of detecting gravitational waves in space. Back on earth a group of ‘A’ level students have been looking at or rather listening to data from space, and published a scientific paper on their observation of a solar storm. In a unique partnership with university physics researchers, information on electromagnetic waves around our planet has been turned into audible data. The keen ears of the students identified events that had not previously been detected. And how incriminating is your washing machine? Digital forensics, the unpicking of the data trails on our digital devices, from phones to TV tuners, even baby monitors and washing machines are now playing a part in criminal investigations, not just cases involving online fraud or cybercrime, but any investigation looking at what suspects were doing and when. A digital trail can act as evidence for time and place.

Adam Rutherford speaks to Dr Tamsin Edwards, a lecturer in Physical Geography at Kings College London and a lead author for the latest IPCC report. Dr Edwards describes what happens in the making of the report, including the summarising of the wealth of scientific literature available into an understandable document for the policy makers. Cairngorms National Park in Scotland is part of an ambitious project to restore the habitat to its former natural state. Four organisations have joined together as the 'Cairngorms Connect’ project – Scottish Natural Heritage, the Royal Society for the Protection of Birds, Wildland Limited and Forest Enterprise Scotland. Graeme Prest of Forest Enterprise Scotland explains how the project team will start to restore the habitat. The grass pea is a resilient and highly nutritious legume but it contains varying level of toxins. Marnie Chesterton visits the John Innes Centre in Norwich to meet the researchers working on making the grass pea less poisonous, which could aid food security, particularly in sub-Saharan. The Sun is technically a G-type main sequence star, which means it’s a giant continuous nuclear fusion reaction plasma, spewing out extremely dangerous matter and energy in every direction, and when it hits the Earth, this can cause all sorts of problems. Adam visits the Science Museum in London to meet Harry Cliff, a physicist and curator of a new exhibition: ‘The Sun: Living With Our Star’, which explores our relationship with the closest star to earth. Adam also finds out from Professor Chris Scott of Reading University about a citizen science project called Protect our Planet from Solar Storms.

Adam Rutherford reviews this year's Nobel science prizes, and talks to Professor Venkatraman Ramakrishnan, a 2009 laureate and president of the Royal Society, about the experience of being tipped as a Nobel winner. This can included a stressful condition known as Pre-Nobelitis and having unidentified Scandinavians turn up in the audiences of your scientific talks. The Japanese space probe Hayabusa 2 dropped an exploratory robot onto the surface of the asteroid Rguyu early on Wednesday morning. The autonomous probe is called MASCOT. With 16 hours of battery life, it landed at one spot on the asteroid's southern hemisphere, took a slew of data and then jumped to another location for more image-taking, temperature and magnetic measurements and chemical analyses of the rocks. MASCOT project manager is Dr Tra-Mi Ho of the German Space Agency. A critical meeting of the International Panel on Climate Change is underway in South Korea. Scientists and government representatives aim to finalise a policy road map to limit global warming to a 1.5 degree C increase by the end of the century. BBC News environment correspondent Matt McGrath is reporting from the meeting and explains why 1.5 degree C and not 2 degrees is the new preferred target for many scientists and nations. But will scientists and policy makers from around the world see eye to eye? Physicist Helen Czerski provides Adam with a final report at the end of her 8 week expedition at the North Pole which aimed to explore the interactions of water, ice, atmosphere and life in shaping Arctic weather and climate. The adventure ended with a crunch and the loss of thousands of pounds worth of scientific kit. Producer: Andrew Luck-Baker

Japan’s Hayabusa-2 spacecraft has arrived after more than a three year journey at the Ryugu asteroid which is just over half a mile long. It has successfully sent probes onto the surface and is sending pictures back to Earth. Gareth Mitchell discusses the achievement with BBC Science Correspondent Jonathan Amos. A hundred years ago, the 1918 flu pandemic killed between 50 and 100 million people worldwide and infected around half a billion. Seasonal flu accounts for about 650,000 deaths per year. As this year’s flu season approaches, there are new insights into how the influenza virus causes disease and why some strains like the 1918 one (a subtype of the avian strain H1N1) are so deadly compared with the seasonal kind. In the most serious cases, there’s an extreme immune reaction in the lungs, and people can effectively suffocate. The latest research from the universities of Cambridge and Oxford has uncovered a molecule that might be behind that immune overreaction. Dr Aartjan te Velthuis explains the findings and the implications for novel treatments. The massive bombing raids on cities in World War Two lead to terrible human tragedy, Now a historian and a physicist have been looking at how shock waves from some of the major bombing over Berlin caused the upper atmosphere above Slough to wobble. Specifically they’re interested in the layer eighty to a thousand kilometres up that reflects radio waves, the ionosphere. Historian Patrick Major and meteorology expert Christopher Scott, both professors at the University of Reading, tell Gareth about their collaboration and how monitoring changes in the ionosphere today can reveal both man made and natural explosive events. And Adam Rutherford talks to Professor Sarah-Jayne Blakemore of UCL about her book, Inventing Ourselves: the Secret Life of the Teenage Brain, the last on this year's shortlist for the Royal Society Insight Investment Science Book Prize.

The Science Gallery London at Kings College London, right under the Shard, is a brand new venue for the collision of art, science and culture, and its opening exhibition is called Hooked, a series of installations and works by people who have experienced addiction. Adam Rutherford explores the neuroscience, the psychology and the epidemiology of addiction; what the latest research says about what addiction is, and how that can help us treat people experiencing addiction. He discusses these questions with psychologist Dr Sally Marlow and neurologist Professor Mitul Mehta who are both at Kings College and have been involved in the exhibition, and Dr Suzi Gage from Liverpool University who studies the epidemiology of addiction. He also talks to the curator of Hooked, Hannah Redler Hawes, and to two of the Science Gallery Young Leaders, Elly Magson and Mandeep Singh, who show him a couple of the exhibits.

A new discovery of abstract symbolic drawings on a rock has been found in the Blombos Cave, about 300 km east of Cape Town in South Africa. The fragment - which some say looks a bit like a hashtag - puts the date of the earliest drawing at 73,000 years ago. As archaeologist Chris Henshilwood tells Adam Rutherford, the discovery is a "a prime indicator of modern cognition" in our species. Nearly half the human genome contains genes that regulate what your organs should be doing at a specific time of day, This has enormous potential importance to the efficacy of drugs - what time of day you take them could be a real issue. John Hogenesch from Cincinnatti Children's Hospital has been studying the genes that cycle with our daily lives. His new database of cyclic genes could help plan the best timing for a host of therapeutic interventions Physicist Helen Czerski has been in the Arctic for the last five weeks, aboard the Swedish research vessel and ice breaker Oden. As the expedition comes to a close we hear about the team's attempts to elucidate the driving forces behind the unusual weather patterns around the North Pole. Inside Science has been profiling authors shortlisted for the prestigious Royal Society science book prize. This week it's mathematician Hannah Fry's new book, Hello World: How to be human in the Age of Machines. You can hear extracts from it on Book of the Week on Radio 4 all this week too. Producer Adrian Washbourne.

Adam Rutherford takes the show to Dublin this week, to wrestle with great matters of biological complexity. Trinity College Dublin has organised a mass gathering of some of the world's leading researchers in the life sciences to mark the 75th anniversary of one of the most influential series of lectures in the 20th century. The talks were delivered by the celebrated physicist Erwin Schrodinger in 1943 who applied his mind to a fundamental biological question: what is life? Some of his ideas were an influence on Francis Crick as he worked on the structure of DNA. Seventy five years on, Adam is joined by four of the many scientists delivering their own lectures this week. They tackle subjects of complexity in biology, ranging from the origin of complex life, the increasingly messy structure of life's evolutionary tree, the functioning of the human brain as a network of many component parts, and the place of neuroscience discoveries in the building of artificial intelligences. The guests are: Nick Lane, evolutionary biochemist at University College London, Beth Shapiro, evolutionary geneticist of the University of California Santa Cruz, Danielle Bassett, physicist and neuroscientist at the University of Pennsylvannia, Murray Shanahan, artificial intelligence researcher at Imperial College London and Google's DeepMind The podcast version ends with a question and answer session with the show's audience who include a surprise celebrity guest. Producer: Andrew Luck-Baker.

Scientists have shown how an electronic gadget, implanted in the brain, can detect, treat and even prevent epileptic seizures. Epilepsy is usually treated using anti-epilepsy drugs, but can cause serious side-effects. Researchers at the University of Cambridge, are aiming to create something more specific to the part of the brain with the problem. Professor Malliaras tells Marnie Chesterton about the unique properties of this new implant, which could be used for a range of brain-related conditions from Parkinson’s tremors to brain tumours. Many of Britain’s cleaner urban rivers are home to levels of biodiversity not seen for decades. But rural rivers, even in places without pollution, tell a different story. Up in the hills of central Wales, just north of the Brecon Beacons, lies the Llyn Brianne observatory and its surrounding system of beautiful streams. Professor Steve Ormerod from Cardiff University has been taking stock of the dwindling number of specialist invertebrates and the subtle ways the decline is happening which points to an extinction crisis that has gone unnoticed. Marnie Chesterton checks in with bubble physicist Dr Helen Czerski. She’s part of a team of researchers aboard the icebreaker Oden research vessel, which is trying to understand arctic weather patterns and how the contents of open water between ice flows influence cloud behaviour. It’s a race against time to gather data before any water refreezes as the arctic winter approaches. Inside Science has been profiling authors shortlisted for the prestigious Royal Society science book prize. This week it’s the turn of materials scientist Mark Miadownik, His new book “Liquid: The delightful and dangerous substances that flow through our lives” is about fluids and how their particular properties allow life to flourish. Presenter Marnie Chesterton Producer: Adrian Washbourne

The last banana you probably ate was a type called Cavendish. But this, our last commercially viable variety is under severe threat, as the fungus, called Tropical Race 4, is laying waste to swathes of Cavendish banana plants across China, Asia and Australia. Recently, scientists & horticulturalists gathered in Istanbul to discuss the best ways to fight the threat. Professor James Dale from the Institute of Future Environments at the University of Queensland has been conducting successful field trials in previously infected areas with impressive results. Could gene editing provide the solution? The extraordinary shape of the guillemot egg is one of ornithology’s great mysteries. This seabird lays something twice the size of a hen’s egg, which looks a bit like an obelisk, blue, speckled and weirdly elongated at one end, with almost flat sides. There have been a handful of theories to explain why it’s evolved. Professor of behaviour and evolution Tim Birkhead, at the University of Sheffield shows in his new research that the answer lies in allowing the birds to successfully breed on the steep slopes of cliff ledges. Marnie Chesterton meets the next in Inside Science’s series of writers shortlisted for the very prestigious Royal Society’s Book Prize : Lucy Cooke, zoologist, author and broadcaster discusses The Unexpected Truth About Animals which flies the flag for some of the lessons learnt from mistakes made in understanding animal behaviour. Could the Tambora volcanic eruption in April 1815 be responsible for Napoleon’s defeat at Waterloo? A rain-soaked battlefield in June 1815, stopped Napoleon deploying his military might although many have questioned how a volcano could have such an effect on the weather so soon. How was it to blame for a Belgian rainstorm just several weeks after the end of the eruption? Dr Matt Genge from Imperial College, in a new paper out this week, says the answer lies in the phenomenon known as electrostatic levitation. Presenter: Marnie Chesterton Producer: Adrian Washbourne

Researchers have found a way to produce a naturally occurring mineral, magnesite, in a lab, that can absorb CO2 from the atmosphere, offering a potential strategy for tackling climate change. They've accelerated a process that normally takes thousands of years to a matter of days, using panels made from tiny balls of polystyrene. Gareth Mitchell meets Ian Power of Trent University in Ontario who led the research. Could this be a viable technology for tackling global warming and carbon dioxide in the atmosphere? What if something as natural as beetroot - or specifically defined doses of beetroot juice - could help alleviate cardiovascular disease and improve the pumping function of failing hearts? That's the idea behind a major trial underway at the Barts Heart Hospital and Queen Mary University in London. Amrita Ahluwalia, co-Director of the William Harvey Research Institute and Christopher Primus a specialist in heart failure, are interrogating the natural nitrates in foods like beetroot and how they could be beneficial to our cardiovascular system. Cells in our bodies can go wrong and end up proliferating into cancers. Intuition might say the bigger something is, the more cells it has and thus, greater is its risk of developing cancer. But elephants have somehow re-awakened a gene that kills cells that could be cancerous before they have time to cause any damage. Vincent Lynch of the University of Chicago has been looking at the genetics that keeps these giants virtually, immune which could hold clues for tackling cancers in humans. And we hear from Simon Winchester, the next in our series of interviews with the shortlisted authors for this year's Royal Society Insight Investment Science Book Prize. Exactly, is an intriguing history of precision, the search for ever greater engineering accuracy and how it changed the world. Presenter: Gareth Mitchell Producer: Adrian Washbourne.

Astronomers this week have been warming up for an encounter as far from the Sun as ever attempted. It's the finale of the New Horizons mission which successfully passed Pluto in 2015 and is now on its way to Ultima Thule - a Kuiper belt object on the edge of the solar system. Marc Buie is just back from Senegal where he and a team of fellow astronomers have been observing this ancient rock to get a final look at its size and shape, before the momentous flyby on Jan 1st 2019. He explains why the encounter will be so valuable in unlocking key secrets in the formation of our solar system. It's the 150th birthday of the discovery of helium, which, after hydrogen is the second most abundant element in the universe. It's surprisingly rare on Earth, but it makes up much of the content of the gas giants in our local neighbourhood, Jupiter and Saturn. Adam Rutherford hears from particle physicist and Science Museum curator Harry Cliff on how it was first discovered through a telescope rather than in a lab, and Jessica Spake of Exeter University who after an 18-year search has used similar techniques to discover helium around an exoplanet 200 light-years away. We hear from scientist and author Dan Davis from the University of Manchester, the next in our preview of authors shortlisted for this year's Royal Society book prize. The Beautiful Cure, is the rollicking story of how the intricate immune system came to be understood. And there's an update from physicist Helen Czerski. She's part of a 40-strong team of field scientists on board the Oden, a Swedish ice breaker and research ship. They're set to find a suitable iceberg, and moor to get to grips with the factors that guide the arctic weather patterns. Producer: Adrian Washbourne.

The sun still has many mysterious properties. The Parker Solar Probe, launched next week will be the closest a spacecraft has ever flown to our star. It's a mission that's been on the drawing board for decades which space scientists have only dreamt of. It will fly into the mysterious solar corona, where so much of the action at 3 million degrees centigrade takes place. Nicola Fox from Johns Hopkins University is the Parker Probe Project Scientist. Adam Rutherford speaks to her from Cape Canaveral, where they are making the final adjustments for the most ambitious journey ever, to the Sun. We meet two scientists who are making a real difference in promoting diversity and equality in the lab. Physicist Jess Wade has been chipping away at this issue, most recently in a heroic project to write up a Wikipedia entry for a scientist who is also a woman every day for the last 270 days and counting. Emma Chapman is an astrophysicist, and last month won the prestigious Royal Society Athena Prize for her work in driving policy changes about sexual harassment at universities. Today the shortlist of the most prestigious of the literary prizes for the sciences was announced - the Royal Society Insight Investment Science Book Prize. This is the 31st prize, and previous winners are a who's who in truly great science writing. Frances Ashcroft, Professor of Physiology at Oxford is the chair of the judges and discusses the books they have selected. Physicist Helen Czerski and 40 colleagues are now aboard the Oden, a Swedish icebreaker and scientific research vessel that set sail earlier this week. They are en route to spend a month anchored to arctic sea ice to elucidate the mysterious behaviour of arctic weather. Before she set off she gave Adam Rutherford a preview of the research trip. Producer Adrian Washbourne.

The European Space Agency's satellite Mars Express has identified what we think is a subterranean lake of liquid near the south pole of the red planet. The question of water on Mars has been around for years, and we've known about water ice, and there's been the possibility of seasonal flowing water on Mars for a while. But if this result is right, this is the first case of a substantial stable body of liquid water on Mars. Adam Rutherford talks to Roberto Orosei of the Radio Astronomy Institute in Bologna whose team made the discovery. Where should scientists be directing their efforts next in the light of this new finding? We hear from NASA's Chief Scientist Jim Green. We've been growing embryonic cells in petri dishes for a few years now, to try to fill in the gaps in our understanding of early development, but the tissue that grows never really resembles an actual embryo. Magdalena Zernicka Goetz is a developmental biologist from Cambridge University and in a paper out this week has leapt over this hurdle in developmental biology using three types of stem cell, which - unlike previous efforts - push a ball of cells to becoming an embryo, which could help us understand why pregnancy can fail. The Earth Biogenome Project aims to sequence the DNA of all the planet's eukaryotes, some 1.5 million known species including all known plants, animals and single-celled organisms. The project will take 10 years to complete and cost an estimated $4.7 billion. Harris Lewin from UC Davis is spearheading this scheme. How will he meet his ambition to curate all the DNA of life on Earth? For the first time, scientists have assessed how much of the seas are untouched by the impact of human activity. They're referred to as Marine Wilderness, and qualify as such by being relatively untouched by things like fishing, pollution or agricultural run-off. According to the survey, published today, only 13% of the world's oceans remain as wilderness. James Watson from the University of Queensland discusss the action that needs to be taken if these precious ecological areas are to survive. Producer : Adrian Washbourne.

The wildfires on Saddleworth Moor may well be the most widespread in modern British history. Thanks to herculean efforts by Greater Manchester Fire and Rescue Service and the military, they are now extinguished, though the peat continues to smoulder. Now the longer term ecological impact is being assessed. Adam Rutherford talks to geochemist Chris Evans from the Centre for Hydrology and Ecology about what's been unleashed into the environment from the burning of the peat and lessons we've learnt in maintaining peatlands. Coral reefs are noisy places filled with the clicks, pops, chirps and chattering of numerous fish and crustaceans. But a new study conducted on Australia's Great Barrier Reef shows that this noise has been quietened in areas damaged by bleaching and cyclones. Marine biologist Tim Gordon of Exeter University has examined how the changing coral acoustics are impacting on fish communities and whether a "choral orchestra" could help reduce the decline in local reef systems. Adam Rutherford meets Magdalena Skipper, the new Editor-in-Chief of the journal Nature. It's a longstanding publication, founded in 1869 and is the cornerstone of scientific endeavour. But how will Nature evolve as the demands on research change and scientific publishing continues to undergo a revolution in the digital age? In order to go very far in space, future astronauts will need some means of creating their own air and fuel. Katharina Brinkert at California Institute of Technology has succeeded in harvesting hydrogen from water in microgravity - overcoming a huge hurdle in the weightlessness of space, that may one day lead to a way to acquire fuel during a long-distance, crewed space mission. Producer: Adrian Washbourne.

Scientists have found the earliest known evidence of a human presence outside Africa. A set of 96 stone tools has been found in the mountains of south-east China, which is the furthest afield this type of tool has been located. The scientists who found them have put the date of these tools at 2.1 million years old, which is at least 300,000 years earlier than the current evidence for early human presence outside of Africa. John Kappelman, a paleoanthropologist at the University of Texas, discusses how we're now moving beyond a Eurocentric view of human evolution in Eurasia. Much of northern Europe has been experiencing a heatwave - notable for its intensity and duration. It's caused by "atmosphere blocking". Can we predict when these blocks will come and how long they will last? Adam Rutherford talks to Jana Sillmann, director of the Centre for International Climate Research in Oslo, Norway, author of a new study that has modelled 40 years' worth of heatwaves and blocking, and looked to the end of the century in attempting to predict blocking patterns as the climate changes. How can researchers get to grips with the shape of molecules in the digital world? Chemists have for years used ball and stick representations of the shapes their molecules come in. But when they publish, they have to flatten it all down onto a 2D a piece of paper losing crucial information. Bristol University's David Glowacki has put the power of virtual reality into the hands of the molecular magicians. Inside Science's Roland Pease went to his virtual lab, to see atoms dance in a molecular space odyssey. Given that half the world is in the dark half of the time, and the depths of the oceans are perpetually hidden from sunlight, there's lot of darkness to explore. For those of us drawn to the shadows, a new exhibition at the Natural History Museum in London does exactly that. Geoff Boxhall, professor of invertebrate biology, gives Adam Rutherford a tour of Life in the Dark. Producer Adrian Washbourne.

The northern white rhinoceros is the world's most endangered mammal. The death earlier this year of the last male of this rhino subspecies leaves just two females as its only living members. New research out this week has adopted new techniques in reproductive medicine as a last ditch attempt to preserve these animals. Thomas Hildebrandt from Leibniz Institute for Zoo and Wildlife Research and Terri Roth, Director of Conservation Research at Cincinnati Zoo, discuss the ambition, and how realistic this approach is in future animal conservation. Earthquakes are scientifically measured with seismometers, but few are present on the sea floor, where earthquakes that can cause tsunamis originate. But could communication cables traversing the oceans fill in the gaps? Giuseppi Marra from the National Physical Laboratory in Teddington, discusses his accidental discovery that fibre-optic cables might be registering the earth's vibrations. For the first time in the annals of science, a tweet was the key reference in a paper reporting on a discovery that a rare wild variety of the gardener's favourite - Heuchera, thought to be limited to a few rocky outcrops in Virginia - is actually abundantly present 100km away. It's all come about because of a picture shared on Twitter. Reporter Roland Pease retraces the tale of the tweets with the key players. Can the size of a roar be used to accurately determine physical strength?' Or can a roar deceive, and make you sound tougher than you actually are? That's what Jordan Raine from the University of Sussex decided to find out, not with lions or tigers or bears but in us. Producer Adrian Washbourne.

Yesterday a small Japanese ion-thruster spaceship arrived at its destination after a three year and half year, 2 billion mile journey. Hyabusa2 is currently floating alongside the asteroid known as 162173 Ryugu. BBC Science Correspondent Jonathan Amos dissects the aims of this audacious sample-return mission and the initial images that have just arrived back on earth. There's a plethora of neutrinos flowing through your body right now. Adam Rutherford goes inside 'protoDune', the world's latest and largest neutrino detector whose prototype is about to be filled with over 700 tonnes of liquid argon and hopefully pick up a few signals generated by interactions from these elusive particles. We hear from project leader Christos Touramanis who is a particle physicist from Liverpool University. Caledonian crows craft tools with greater sophistication than most animals, and can learn to modify their tools to make them gradually more effective. This "cultural accumulation" is commonplace amongst humans - where we pass on information socially. But it's extremely rare in other animals to see them passing on knowledge in this way. Sarah Jelbert from Cambridge University discusses her new evidence that suggests crows manage to transmit their tool designing skills from one bird to another in this sophisticated way Our gut bacteria are emerging as key determinants of our health and the microbiome may even influence our behaviour. The interaction between ubiquitous bacteria and the food wild animals eat is beginning to be studied all over the world. Could manipulating the microbiome prove a new tool for conservation in animals whose food supply is under threat? Ecologist Ben Moore from Western Sydney University has been studying the eating habits of koalas and whether faecal transplants could alter the eating habits of this highly fussy herbivore. Producer Adrian Washbourne.

It's been 8 years since the Large Hadron Collider went online and started smashing protons together at just below the speed of light. CERN announced this week that they're ready for a massive upgrade, and on Friday last week, there was a ceremony to break ground on what is being called the High luminosity LHC. Particle physicist Jon Butterworth from UCL discusses the next generation of particle accelerators that are undergoing early trials and what the newly announced upgrade means for particle physics. Medical surgeons routinely stitch or pin organs and blood vessels with needle and thread and secure medical devices like pacemakers with hooks. But what if you could just use glue? Material scientist Terry Steele from Nanyang Technological University in Singapore has devised Voltaglue, a flexible adhesive that works in wet environments by putting an electric current across an inert substance. He explains how this new kind of chemistry could revolutionise many medical procedures. This weekend Sir David Attenborough will reopen The Museum of Zoology at Cambridge University. It's undergone a five-year redevelopment, showcasing thousands of incredible specimens from across the animal kingdom, and exploring stories of conservation, extinction, survival, evolution and discovery. Adam Rutherford visits the new displays under the watchful eye of conservator Natalie Jones and zoologist and museum manager Jack Ashby. And Professor Tim Birkhead of the University of Sheffield discusses The Wonderful Mr Willughby - his fascinating new account of 17th century ornithologist Francis Willughby who together with the celebrated naturalist John Ray pioneered the way we think about birds in science. Producer Adrian Washbourne.

Adam Rutherford goes totally polar this week with news of accelerating ice melt in Antarctica, two visions of the continent's future, and the sounds of collapsing icebergs and the songs of narwhals. Two hundred billion tonnes of Antarctic ice are now being lost to the ocean every year, pushing up global sea level by 0.6 millimetres a year. This is a three fold increase since 2012. This finding comes from IMBIE, the Ice Sheet Mass Balance Intercomparison Exercise. Leeds glaciologist Andy Shepherd and Durham earth scientist Pippa Whitehouse tell Adam how the project made this startling finding and what it may mean for global sea level rise in the future. Glaciologist Martin Siegert of Imperial College London has co-authored an unusual Antarctic paper in the journal Nature this week, with other leading south polar researchers. It is a history of the frozen continent, looking back from the year 2070 and charts two different courses that we could be on today. Satellites above the Antarctic and Arctic can only tell us so much about the melting and collapse of the ice sheets. Oskar Glowacki of the Scripps Institution of Oceanography is exploring what extra insights might come from recording the underwater sounds that ice sheets make when they collapse and melt in Arctic seas. The narwhal, sometimes known as the unicorn of the sea, is one of the world's most elusive and poorly studied cetaceans, primarily because it spends much of its life underwater and under ice in the Arctic. Marine biologist Susanna Blackwell led a team which used sound recorders and satellite tags attached to several narwhals in Eastern Greenland, to follow their lives continuously for an unprecedented length of time. Producer: Andrew Luck-Baker.

A spectacular predatory dinosaur fossil was auctioned this week in Paris. It was bought by a private collector at the cost of about 2 million Euros. Academic palaeontologists are not happy about the sale. Anjali Goswami of the Natural History Museum and Steve Brussatte of Edinburgh University air their views to Adam Rutherford on the legal and illegal markets for premium vertebrate fossils. Who owns the genetic biodiversity of the oceans? One single multinational corporation - the chemicals giant BASF - has registered almost half of all known patents on genetic sequences from marine organisms. This is the headline finding of a survey of marine genetic resource ownership by David Blasiak of the Global Resilience Centre at Stockholm University. Immunotherapies for cancer have been in the news in the last week. Adam talks to cancer researchers Sophie Papa of Kings College, London and Samra Turaljik of the Royal Marsden Hospital about the principles behind immunotherapy and the different approaches in the clinic and under clinical trials. Producer: Andrew Luck-Baker

Adam Rutherford and his guests at the Hay Festival, neurologist Dr Suzanne O'Sullivan, acoustic engineer Professor Trevor Cox and science writer Dr Philip Ball discuss what scientists learn when things go wrong. Suzanne O'Sullivan, author of Brainstorm, talks about how she helps her patients with strange and unusual forms of epilepsy; Trevor Cox, whose new book is called Now You're Talking, describes cases where our voices change, such as stammering and foreign language syndrome; and Philip Ball, who is part of Created out of Mind, a Wellcome funded project about dementia and the arts, explores what happens when our brains age.

New research suggests that rice will be depleted in important B vitamins and minerals by rising CO2 levels in the atmosphere. Adam Rutherford to talks to Kristie Ebi of the University of Washington, one of the scientists behind the finding, and consults Marco Springmann of the Future of Food project at the University of Oxford. Is the future of farming subterranean? Marnie Chesterton visits a farm called Growing Underground for some answers. Specialising in salad and herbs, it is located beneath Clapham Common in South London in an old Second World War air-raid shelter. Has an interstellar asteroid been lurking in our solar system for more than four billions years? It's a possibility according to the astronomers who've watched and plotted its strange orbit. It travels around the Sun in the opposite direction to most of the planets, asteroids and comets. Asteroid specialist Alan Fitzsimmons of Queens University Belfast talks to Adam about this astronomical oddity and assesses the evidence for it being a traveller from the stars, captured by our solar system during its early childhood. Stephanie Wright of Kings College London explains about what we do and don't know about the abundance and health risks of microplastic particles in the air we breathe. Producer: Andrew Luck-Baker.

Facial recognition technology is on the rise and in some places used to fight crime. In the UK the police have been heavily criticised for falsely identifying people using the technology. But are their results really that bad? Professor Hassan Ugail tells Adam Rutherford that – though there is room for improvement – the results may not be as catastrophic as critics claim. Wild flowers are being outcompeted by ‘thug’ plants on our roadside verges, a study by the charity Plantlife has found. Pollution from cars and poor management practices by local councils has meant that nitrogen-loving plants outcompete wildflowers. Dr Trevor Dines explains to Adam Rutherford what actions can be taken to help our verges regain their natural biodiversity. A new study reveals that for every pound a female scientist receives for her cancer research a male scientist will get one pound and forty pence. This gender imbalance in cancer funding highlights wider issues around women in science and how funding councils operate. Adam Rutherford discusses the problem with chief scientist at Cancer Research UK, Karen Vousden, and Professor Henrietta O’Connor, who co-authored the study. This week Adam Rutherford marks the birthday of one of the greatest of all physicists: Richard Feynman. Professor Jonathan Butterworth talks about Feynman’s legacy as a scientist and science communicator but also about his highly problematic views on women.

On the remote island of South Georgia, the invasion of rats from passing ships has wreaked havoc on the local wildlife. But the South Georgia Heritage Trust announced this week that all rats have been eradicated thanks to an extensive project. Adam Rutherford speaks to chairman Professor Mike Richardson about the achievement and how the wildlife is already healing. Elephants don’t only communicate using their trunks but also their feet. A new study taps into this underground communication using seismic equipment to detect the vibrations. Dr Beth Mortimer explains how the technology may help to react in real-time to elephant distress such as panic running – for example – when being hunted by poachers. We all know how dinosaurs became extinct but how did they rise to prominence? Author of the new book “The Rise and Fall of the Dinosaurs” Steve Brusatte talks about how the beloved creatures came to dominate the Earth and the new technologies being used to discover even more about them. How does science help us understand snooker? From the importance of chalking cues to how physics explains extraordinary snooker shots. Adam Rutherford tries to find out how he can up his game with the help of physicist Dr Phil Sutton.

The Thwaites glacier in Western Antarctica is twice the size of the UK and accounts for about 4% of sea level rise, but what is unknown is whether the glacier will collapse as a result of environmental change. Adam Rutherford speaks to 2 scientists from a major new study who with the help of seals and Boaty McBoat face will be investigating what goes on under the glacier and what drilling into the rocks under the sea can tell us. And while the work of the new Antarctic team-up is studying the impact of the rise of sea levels, here in the UK, researchers are similarly concerned about the warming of the oceans, but on the specific effect it could have on sea birds. Inside Science's Jack Meegan reports from the Yorkshire coast. The Temperate House at Kew has undergone a 5 year restoration and now is about to open to the public, Adam goes along to get a preview. Who owns ancient DNA? A recent article in the journal Science argues that we need to think harder about the living relatives of indigenous people and not simply treat their human remains as "artifacts".

As the field of neuroscience advances, scientists are increasingly growing brain tissue to study conditions like autism, Alzheimer's and Zika virus. But could it become conscious? And if so, how far away is that scenario? Wind, changing water temperatures and salt are all factors known to control ocean currents. But new research suggests there's another element in the mix. When sea monkeys amass, the thousands of swimming legs can create powerful currents that mix hundreds of meters of water. Whenever a baby is born, we ask whether it's a girl or a boy. But when it comes to puppies, the question is often about the breed, especially with mongrels. And when we think we know what it is, we make assumptions about how that dog will behave. For instance, if you think there's some golden retriever parentage, you may expect it to be good at playing fetch. But do our perceptions of dog breeds change the way it behaves? That's the question of a new citizen science project called MuttMix, which asks you to guess the ancestry of various mongrels. Finally, Charles Dickens is known as one of the best novelists of the Victorian era but a new exhibition is questioning whether he should be also known as a man of science. Dickens campaigned for paediatrics and his powers of description lead to a new conditions being medically recognised. The exhibition will be at the Charles Dickens Museum and it opens in May.

A breakthrough for closed loop plastic recycling? Two years ago Japanese scientists discovered a type of bacteria which has evolved to feed on PET plastic - the material from which fizzy drink bottles are made It was isolated at a local recycling centre. An international team has now characterised the structure of the plastic-degrading enzyme and accidentally improved its efficiency. John McGeehan of the University of Portmouth led the team and talks to Adam about where the discovery may lead. If you can't recycle plastic, you can re-use. Sheffield University chemist Tony Ryan is working to convert old polyurethane foam mattresses into hydroponic allotment beds so that people at a Syrian refugee camp in Jordan can grow their own crops. Roland Pease reports. How southeast Asian sea nomads evolved the life aquatic. The Double Helix, fifty years after its 1968 publication. Biologist and historian Matthew Cobb and science writer Angela Saini discuss the place of James Watson's compelling and controversial memoir in the annals of popular science writing. His account of the discovery of the DNA's structure was unlike any science book that had come before. Does it stand the test of time and what of its blantantly sexist treatment of the gifted X-ray crystallographer Rosalind Franklin? Her work was crucial to Crick and Watson's 1953 model of the DNA molecule.

A few weeks ago, Inside Science featured an item on neonicotinoids and the negative impact these pesticides have on insects like honey bees. The discussion turned to alternatives, including organic farming. Many listeners wrote in about some issues that went unchallenged. So this week, Adam returns to the subject to get into the nuts and bolts of both organic and conventional farming. Next week sees the launch of a NASA mission called TESS. The Transiting Exoplanet Survey Satellite is surveying the brightest stars near Earth and looking for habitable planets. Roland Pease reports. Traditionally, the move from Bronze Age to the Iron Age is estimated to be around 1200 BCE. But recent excavations of smelting sites in Uttar Pradesh in India suggest that this date might be a few centuries late and that it might even originate in Asia. Adam visits The Rutherford Appleton Laboratory in Oxfordshire to see how a particle accelerator is revealing the details of the Indian Iron Age. Our ancestors bore a very prominent brow ridge, which scientists think was a symbol of dominance. Modern humans, however, have lost this ridge in favour of a flatter forehead. Why? Dr Penny Spikins and her colleagues think the answer lies in social interaction and in particular, the ability to raise your eyebrows.

Adam Rutherford presents a special tribute to the science of Stephen Hawking. He is joined by Fay Dowker, a former PhD student of Hawking and now a professor of theoretical physics at Imperial College, Professor Carlos Frenk, a long-time colleague and friend and fellow physicist and science communicator Professor Brian Cox. They look at the scientific legacy of Stephen Hawking and the role that his work played in bringing us a step closer to a single grand theory that explains how the universe works.

A widely reported study published last week suggests that on average children at selective schools have more gene variants associated with higher educational attainment than children at non-selective schools. It also suggests that selective schools achieve better GCSE exam results because their selection procedures favour children with those genetic variants, and not because of the teaching and facilities at private and grammar schools. Adam Rutherford talks to the senior researcher Robert Plomin of the Institute of Psychiatry in London, and Ewan Birney, director of the European Bioinformatics Institute near Cambridge. John Goodenough invented the lithium ion battery, the power pack that makes our smart phones, tablets and laptops possible. At the age of 95, in his lab at the University of Texas, he's now working with colleagues such as Portuguese physicist Helena Braga on an even better next generation battery technology: one that could transform the prospects for electric vehicles and renewable energy storage. Roland Pease meets the jovial battery pioneer and his team. Hunting regulations in Sweden are having a profound effect on the behaviour of brown bears in the country. Since the 1980s, hunters are not allowed to shoot female bears with cubs. Historically, mother bears stayed with their cubs for 1.5 years but as hunting rates increased, mothers began to keep their offspring with them for an additional year. Now more than a third of mothers look after their cubs for 2.5 years. According to Andreas Zebrosser of the University of Southeastern Norway and Joanie van der Walle of the Universitie de Sherbrooke, hunting appears to be acting as a powerful evolutionary force on the species' reproductive behaviour.

The story of how Cambridge Analytica had scraped Facebook data in its attempt to influence voting behaviour has been reported widely this week. Andrew Steele, a medical researcher at the Crick Institute in London, explains how data mining or scraping actually works and how it is used by many scientists to find ways of improving human health. The Government Office for Science published a massive report this week, entitled the 'Future of the Sea' which sets out the UK's stall with regard to our future relationship with the seas, and to put science front and centre in that plan. Professor Ed Hill, Executive Director at the National Oceanographic Centre in Southampton, is one of the authors and tells Adam Rutherford about future exploitation of the sea. Debris in space is a huge issue - it's estimated that there are more than 170 million fragments of satellites, rockets and other stuff that we've sent up, all orbiting the Earth at ballistic speeds. All of these have the potential to lethally strike a working satellite or worse, a crewed space station. Graihagh Jackson met Professor Guglielmo Aglietti at Surrey University who's researching the best technology to safely remove space junk. Dinosaurs were incredibly successful and lived on earth for over 150 million years. Francois Therrien from the Royal Tyrrell Museum of Palaeontology in Alberta, Canada, and colleagues explored how living crocodiles and birds, the descendants of dinosaurs, rear their eggs. Dr Therrien told Adam how their findings have suggested that dinosaurs used a variety of ways to hatch their eggs in the many environments on earth.

As spring and Brexit loom, Adam Rutherford examines what stance the UK might take on neonicotinoids. The pesticide has been shown to harm bee populations by many scientific studies. Now, the largest report of its kind has put pressure on the EU to vote on whether three types of neonics should be banned. Will the UK follow Europe's lead if the ban is legislated? Fly tipping is a problem faced by most authorities. But conservationists at the Creekside Discovery Centre in Deptford are embracing the carpets and shopping trolleys that have washed up in their creek in south-east London. They even argue that the rubbish provides a safe haven for wildlife. Graihagh Jackson investigates. Graphene is often touted as a wonder material but now this carbon sheet could be making an unexpected appearance in your bathroom cabinet as hair dye. The world-renowned physicist Stephen Hawking has died at the age of 76. The British scientist was famed for his work with black holes and a general relativity. Inside Science examines his scientific legacy.

A former Russian spy, Sergei Skripal, and his daughter Yulia are in a serious condition after being exposed to a nerve agent on Sunday. The first police officer to attend the scene also remains in hospital. It is being treated as 'a major incident involving attempted murder.' We ask what happens next: what antidotes are available, how do they work and what's the prognosis? Today marks International Women’s Day. Its aim is to celebrate the social, economic, cultural and political achievements of women. But there’s also a strong call for change, especially in the tech industry where women are vastly underrepresented. Discussions on how we could achieve gender equality have been ongoing for years, so why has there been so little change? And how can this bias affect the technology we all use? Scientists are warning of an infertility 'crisis' among men. Sperm counts have been falling for over 40 years and now, 1 in 20 men have low sperm counts. The cause is unknown and this week, doctors are calling for more funding to better understand the issue. The red squirrel has found an unlikely ally: the pine marten. Grey squirrels were introduced to the UK in the late 1800s from America and have since caused the native red population to diminish. However, with the reintroduction of a predator, the mal-adapted greys are being hunted and as a result, red squirrels are bouncing back.

With many parts of the country seeing large snowfalls we ask what's driving our current weather? What factors need to be in place to create snowfalls, and how do these differ from sleet or frozen rain? And we address the impact of climate change, while a series of weather events might show a pattern, at what point should we go looking for explanations beyond natural events? Dutch Elm Disease laid waste to millions of British Elm trees back in the 1970's, Now a new tree bacteria which mimics the effects of drought has spread from the Americas to Europe. It has already been detected in some tree imports to the UK. Unlike Dutch Elm Disease it affects a huge variety of trees and shrubs, from mighty oaks to fruit trees and Lavender bushes. New directives have just been introduced to try and halt its spread. Can we beat dementia? Research from the US amongst people in their 80's and 90's provides grounds for optimism, showing that elderly people with good memories have brain structures which can be more developed than those of people 30 years younger. And yet at the same time they may carry factors usually associated with dementia. And how violent are we? Compared with our past that is. Research from collections of gruesome medieval remains paint a picture of a violent society, where men and women commonly carried weapons and inflicting or receiving severe wounds may have been a part of daily life. And yet other studies suggest this level of violence is actually lower than that experienced in some societies today. Marnie Chesterton presents.

The UK is one of the largest recipients of research funding in the EU. Marnie Chesterton discusses what the future of UK science funding will look like with MP Norman Lamb, who chairs the House of Commons Science and Technology Committee, and Ed Whiting, Director of Policy and Chief of Staff at the Wellcome Trust. Around 4,500 years ago, 90% of the British population was replaced by incomers known as the Beaker people. Across Europe archaeologists have uncovered elements of the Beaker culture - bell-shaped pots, copper daggers, arrowheads, stone wrist guards and distinctive perforated buttons -it's always been a mystery as to whether these finds represent a wave of mass migration or the sharing of ideas between peoples. Now ancient DNA studies show it was both, and for Britain reveal a huge population change which still resonates today. A new collaboration between an artist and a cyclone physicist commences this week.They joined forces to model Hurricane Katrina and cast its shape into six brass bells. Each bell represents a key moment from the category 5 storm, as it progressed across the Gulf of Mexico and made landfall in the United States in 2005. The finished collection will feature in a BBC Radio 4 documentary later this year. And how does the moon affect life on earth? specifically worms - we unearth a species of worm that times its mating ritual by the waxing and waning Moon.

Sulphur belched out of vessels' smokestacks is a serious health problem for coastal communities around the world. Four hundred thousand premature deaths from lung cancer and cardiovascular disease and around 14 million childhood asthma cases annually are reckoned to be related to shipping emissions. The International Maritime Organisation has finally agreed to drastically reduce polluting emissions from 2020. Gareth Mitchell discusses with James Corbett of the University of Delaware the impact of the emissions reduction on health. The nearly complete skeleton of Cheddar Man was found in a cave in Somerset in 1903. He'e been in the news because experts in human face reconstruction have created an image of what he probably looked like based on new DNA evidence. Chris Stringer, Ian Barnes and Selina Brace of the Natural History Museum have all worked with Cheddar Man and they talk to Gareth about how the study of this 10 000 year old skeleton is part of a bigger project to understand how Britain became populated with waves of peoples from Europe in the Mesolithic and Neolithic eras. Scientists at the Max Planck Institute for Intelligent Systems have invented a magnetically controlled soft robot only four millimetres in size that can walk, crawl or roll through uneven terrain, carry cargo, climb onto the water surface, and even swim in it. Professor Metin Sitti, Director of the Physical Intelligence Department at the Max Planck Institute, explains how it works and how he sees the future use of millirobots in medicine - in delivering drugs and targeting cancerous cells. Marnie Chesterton talks to Dr Lisa Wallis from ELTE University in Hungary about her work to improve the cognitive abilities of older dogs... using touchscreens.

This week a US based billionaire launched a giant space rocket and sent a car vaguely in the direction of Mars. As a space mission it was to say the least unconventional, and for those involved in promoting space science it presents a quandary. Is such a mission largely a publicity stunt or is it useful for engaging people in the potential of space exploration? Gareth Mitchell looks at one project which enables schoolchildren to programme computers on the International Space Station and he talks to the European Space Agency about why a rock concert might be a good avenue for exploring space science. As more and more of our everyday lives are conducted online we ask what are the cyber-security threats of today, and how can science be used to counter them. Do we now need new kinds of science to locate, understand and stop new kinds of threat? Can bat science help human ageing research? New findings have show that some long lived bat species do not age in the same way as other mammals. They don't even seem to posses the DNA repair enzyme most commonly found in the animal kingdom. We look at the mystery of why bats seem to have evolved in this way. And have you lost a satellite? Don't worry: a computer geek will find it for you. That's exactly what's happened - an amateur space sleuth has detected signals from a NASA satellite thought to have been 'lost' for years.

In 2016 there was an attempted coup in Turkey. This led to many people who the government saw as opposition figures being sacked from their jobs and in some cases held without trial. They include prominent intellectuals, medics and scientists. In recent days there has been a similar crackdown on people voicing criticism of Turkey's current military actions in Syria. Stephen Reichter, Professor of Psychology at St Andrews University has been to Turkey to observe the trial of one of his former colleagues. He tells us what he saw and discusses the wider issues for science. It's the 60 years since the launch of Explorer 1 and the discovery of the Van Allen Belts. This was the satellite the US launched in response to Sputnik. However unlike Sputnik it did undertake scientific exploration, its findings have been significant for every space mission that followed. Using DNA sequencing scientists have found that the 'Two Brothers' mummies at the Manchester Museum have different fathers so are, in fact, half-brothers. Khnum-nakht and Nakht-ankh - date to around 1800 BC. Ever since their discovery in 1907 there has been some debate amongst Egyptologists on whether the two were actually related at all. DNA was extracted from their teeth to solve the mystery. And the science of the Archers, a current storyline involves leaks of industrial chemicals illegally buried on a farm many years ago. We'll be looking behind the scenes to see where the story came from and how the world's longest running soap opera ensures scientific accuracy. This week's programme is presented by Gareth Mitchell as Adam is away.

What killed the Aztecs? In some areas of the Americas, as many as 95% of the indigenous population died of diseases brought in by the discoverers of the New World. Pandemics hit the population who had little immunity to diseases carried by people and livestock. One outbreak responsible for killing millions started in 1545 and was locally called 'cocoliztli'. But for the last 500 years, exactly what this deadly disease was has remained a mystery. Adam talks to Johannes Krause of the Max Planck Institute who has analysed the teeth of 10 individuals from a mass grave for pathogens and found remnants of typhoid fever DNA. Could this be, in part, responsible for the deaths of millions? Historian Caroline Dodds Pennock from the University of Sheffield discusses the difficulties of knowing for definite what killed so many millions of people. In 2015, Nick Goldman issued a challenge. If anyone could decode the information he had stored on some DNA by 21st January 2018, they could win a bitcoin. When Nick bought the bitcoin it cost about £200. To claim the bitcoin, the winner would have to sequence the DNA and then decrypt a code. In late 2017, Nick thought he would be keeping his bitcoin, now worth thousands of pounds. But PhD student Sander Wuyts got in touch with Nick to claim his prize. Marnie Chesterton follows the story. Adam talks to MIT scientist, Michael Strano about his new techniques to make plants glow in the dark. Could these plants be used as street lighting in the future? And how can sound be used to levitate humans? Professor of Ultrasonics at the University of Bristol, Bruce Drinkwater explains how his team have managed to overcome a size limit on the use of acoustic beams to trap and move objects in space. With no theoretical upper limit on the size of object which can be levitated, he explains how the technology could be used in medicine to deliver powerful drugs to a very specific place. This would leave the rest of the body unharmed or could help in the dispersal of kidney stones.

African Swine fever is deadly to pigs and is spreading west from Russia across Europe. The virus that causes it is very resilient and can stick around on clothing, hay and in infected pork products for as long as 150 days. Biosecurity is crucial to preventing its arrival in the UK. If just one pig eats some infected meat from discarded human food the disease could quickly spread causing thousands of pigs to be culled and costing the industry millions. But what is the current progress on developing a vaccine? Adam talks to virologist Professor Jonathan Ball of Nottingham University and Zoe Davies from the National Pig Association. Simon Boxall from Southampton Oceanography Centre gives an update on the sinking of the oil tanker Sanchi and its environmental impact. CRISPR is a revolutionary gene editing technique which can modify DNA and has the potential to correct genetic errors in a range of human diseases - even cancer. The technique has only been around for a few years but is already being talked about as a Nobel prize winning candidate. The market for the technology has been predicted to be worth US$ 10 billion by 2025. But stocks took a wobble last week on news that our immune system may render CRISPR useless. Is there really a big problem? Adam talks to Matt Porteus from Stanford University who did the research. 18 months ago, New Zealand announced a conservation project to exterminate all vermin that are decimating the indigenous bird population. For millions of years, the flora and fauna evolved in isolation, without predatory mammals. When humans arrived, they brought with them a host of bird-eating animals like rats, stoats and possums which now kill 25 million native birds every year. Marnie Chesterton travelled to New Zealand to report on a campaign of mass poisoning to save the kiwis and the kakapos and asks whether it’s ethical to kill one species to save another. And Cat Hobaiter from St Andrews University responds to listener questions about how chimpanzees might recognise family members.

After the Sanchi oil tanker collided with another ship it discharged its cargo of 1 million barrels of condensate oil. This could cause one of the biggest oil disasters in 25 years. What is condensate, can it be cleaned up and how toxic to marine life is it if large amounts of it leak or the tanker sinks? Adam talks to Simon Boxall from Southampton Oceanography Centre. A long-held belief that babies look more like their fathers is being put to the test by scientists at St Andrews University. They are launching an on-line citizen science experiment asking members of the public to see if they can tell from a group of chimps which are the close relations. Geoff Marsh takes the test and talks to researcher Cat Hobaiter about why it might be advantageous for a baby primate to look like its father more than its mother and what they hope to learn from humans' ability to recognise chimp family trees. A new swallow-able, electronic pill that sniffs out the gas produced in your gut could be the answer to accurately diagnosing and distinguishing between ailments of the gut. The gastrointestinal tract is hard to access so when something goes wrong, conditions like Irritable Bowel Syndrome, lactose intolerance and over production of bacteria. can be hard to distinguish from one another and so accurately diagnosed. Professor Kourosh Kalantar Zadeh from RMIT in Melbourne explains why his device, which senses gases in the gut and transmits its findings back to a smartphone in real time,, is more accurate and less invasive than current breath tests or endoscopies and colonoscopies. And Janet Kelso answers listener questions on human evolution and why modern Europeans still carry Neanderthal DNA.

Adam Rutherford talks to astronomer Tabetha Boyajian at Louisiana State University about the wierd star that's perplexed astronomers since its discovery two years ago. KIC 8462852 has the unique habit of intermittently and sometimes dramatically dimming and then brightening. Some scientists even suggested vast alien megastructures around the star might be the explanation. After twenty months of almost continuous observation, Professor Boyajian has much more information about what the star is doing. But the big mystery hasn't gone away. BBC News science correspondent Jonathan Amos joins Adam to share some highlights in space exploration for the coming 12 months. Zoologists and engineers at the University of Oxford are developing an app that identifies one species of mosquito from another by analysing the sounds their rapid wing beats make. Graihagh Jackson visits Marianne Sinka at the Zoology Department to listen to her collection of mosquito songs. Did the widespread introduction of the food additive trehalose fuel the emergence of epidemics of virulent Clostridium difficile in hospitals from the early 2000s? Microbiologist Robert Britton tells Adam about the evidence his team has gathered and published this week in the journal 'Nature'.

Twenty years ago, a revolution in the study of human evolution began. A team in Leipzig in Germany successfully extracted DNA from the bones of a Neanderthal man who died about 40,000 years ago. Thirteen years later, the same group unveiled the first complete genome sequence of another Neanderthal individual. Last year, they announced they'd retrieved DNA from much oldest archaic human bones, more than 400,000 years old. Adam Rutherford talks to Svante Paabo, the scientist has led these remarkable achievements. Professor Paabo and his colleague Janet Kelso at the Max Planck Institute of Biological Anthropology in Leipzig discuss the genes in many European people alive today that originated in Neanderthals and were passed to modern humans when the two species interbred. Adam also speaks to Johannes Krause who worked on the Neanderthal genome project in Leipzig but is now director of the Max Planck Institute of the Science of Human History. His latest research adds a new layer of intrigue and complexity to the relationship between our species and Neanderthals in deep time. David Reich at Harvard University focuses on using ancient DNA to uncover the ancestry and movements of modern human hunter-gatherers in Eurasia from about 50,000 years to the Bronze Age, a few thousand years ago. Population movements occur on a cinematic scale, he says. (Podcast only). The revelations of ancient genetics would not be possible and meaningful without the traditional disciplines of palaeoanthropology and archaeology. Adam goes to Gibraltar to seek the perspective of Clive Finlayson who leads excavations there as director of the Gibraltar Museum. Gibraltar is the most concentrated site of Neanderthal occupation in the world. As well as remains of a young Neanderthal child last year, the Rock's caves have also recently yielded the first example of Neanderthal cave art.

Promising results from a small clinical trial of Huntingdon's disease patients have led to RNA-directed therapy such as antisense RNA being hailed as possibly a turning point in the treatment of neurodegenerative diseases. Adam Rutherford discusses this class of drugs with Heidi Ledford of Nature News. At the beginning of the month, Donald Trump decreed that two national monument landscapes be drastically down-sized. Strict protections against exploitation were removed from vast tracts of land bearing some of the world's most important fossil bearing strata. President of the Society of Vertebrate Paleontologists, Professor David Polly explains why his organisation is now suing Trump. At Harvard University, bioengineers are growing parts of functioning kidneys in small chips using a form of 3D printing. Jennifer Lewis' lab is doing this to learn how kidneys function and explore the possible therapeutic applications of the mini-kidneys-in-a-chip. Roland Pease visits the team at work. The electric eel can deliver a 600 volt shock, from a stack of electrically charged cells along the length of its body. Inspired by the eel's biology, Michael Mayer and his colleagues at the Universities of Fribourg and Michigan have now created their own version of its electric organ with the help of jelly babies and clever origami. In the future, it could power devices in the human body.

Oxford is hosting the European Coral Reef Symposium this week. Climate change is seen as the number one threat to the future of coral reefs. Adam talks to Morgan Pratchett of James Cook University about the two recent coral bleaching events that hit the Great Barrier Reef, and to Barbara Brown of Newcastle University about the potential for coral species to adapt to warmer seas. After twenty years of excavation and preparation, the most complete fossil skeleton of an Australopithecine has been unveiled to the public in South Africa. Its discoverer Ron Clarke explains its significance for understanding human evolution. December 16th is the 100th anniversary of Arthur C Clarke. Science writer Marcus Chown and cultural journalist Samira Ahmed join Adam to discuss Clarke's visions and works of science fiction.

Trophy hunters are always after the lion with the largest darkest name and the stag with the most impressive antlers. Research by Rob Knell at Queen Mary University of London finds that removing a small proportion of these top males can drive whole populations to extinction, if their environment is changing. Gene drive is a new genetic technology that could be used to eradicate populations of species of 'pest' animals. The Roslin Institute in Edinburgh has just announced it is to begin research on gene drives to control rat and mouse populations. The Institute's Bruce Whitelaw and Simon Lillico explain how the approach would work and argue that it would be humane compared to traditional methods of vermin control. However there are concerns about its potential ecological consequences - namely the risk of female infertility in the targeted species spreading without no geographical limits. Kevin Esvelt of MIT voices his reservations. Bruce Whitelaw outlines how future research aims to bring gene drives under more control. Researchers in the USA and Japan talk about their discovery of nuclear reactions in lightning strikes, and Caroline Brighton and Graham Taylor of the University of Oxford explain why they have been attaching small cameras and GPS units to peregrine falcons and recording the birds chasing drones.

More than 5,000 years of heavy agricultural labour by women can be read from the bones found in ancient cemeteries from the Neolithic to Iron Age times. Cambridge University anthropologist Alison Macintosh compared the arm bone dimensions and strength of women from these times with those of modern female athletes such as runners to rowers. Her conclusion is that average upper body strength of women through the Neolithic to the Iron age times exceeded that of today's semi-elite female rowers. A laboratory at the Scripps Research Institute have created a semi-synthetic bacterium with two new man-made genetic letters in its DNA, in addition to the natural four A, G, T and C. What's more, the engineered microbe can use its enhanced genetic alphabet to build synthetic amino acids into the proteins it makes. Chemist Floyd Romesberg talks to Adam Rutherford about what we can learn from his team's extraordinary feat of synthetic biotechnology, what we might gain from it and why, in his opinion, we've no need to be worried. Adam deals with some of your correspondence on axolotls by talking to laboratory salamander breeder Randal Voss at the University of Kentucky. He also notes listeners' comparisons of the recent visit by interstellar asteroid Oumuamua with the alien vessel in Arthur C Clarke's 'Rendezvous with Rama'. Cosmologist and AI researcher Max Tegmark visits BBC Inside Science to discuss the possibility of artificial intelligence machines with super-intelligence and how humanity should be preparing for their advent. Producer: Andrew Luck-Baker.

On 19th October, a mysterious object sped through our solar system. It was first spotted by astronomers with a telescope in Hawaii. Its trajectory and speed told of its interstellar origins. It is the first body to be detected from outside our solar system. Scientists are now publishing their papers on the enigmatic visitor. They estimate that it was about 400 metres long and bizarrely elongated in shape. Adam Rutherford talks to astronomer Alan Fitzsimmons of Queens University in Belfast. Twenty years ago, geneticist Svante Paabo began a revolution in human evolution science when he extracted fragments of DNA from the 40,000 year old bone of a Neanderthal. Among other first, he went onto sequence the entire genome sequence of Homo Neanderthalenisis. Professor Paabo was in the UK this week at a conference on DNA and human evolution at the Wellcome Genome Campus to mark the anniversary. He tells Adam about one of the new directions of research for him now. What does the future hold for synthetic biology? Who will be the practitioners of this fast-growing branch of bioengineering and what will be its impact on the world - for good and possibly ill? Experts in the field have just published a horizon-scanning report in the journal eLife. One of its authors, Jenny Molloy of the University of Cambridge, talks to Adam about the nascent democratisation of the discipline and where this might lead the field and society. The paradoxical plight of the axolotl: popular aquarium pet, laboratory animal and critically endangered species in the wild. This species of salamander is a wonder of nature. It's the amphibian that never grows out of its larval stage yet it's able to reproduce. Most remarkable is its ability to regrow limbs, which is of great potential interest to researchers developing regenerative medicine. There are many thousands of axolotls in labs and homes around the world. But in the wild, in their native Mexico, they are on the very edge of extinction. Inside Science talks to conservation biologist Richard Griffiths of the University of Kent and axolotl researcher Tatiana Sandoval Guzman of the Technical University in Dresden, Germany. Producer: Andrew Luck-Baker.

What might the length of the day have to do with the likelihood of destructive earthquakes around the world? According to Professors Rebecca Bendick and Roger Bilham, there's a correlation between changes in the rate at which the Earth rotates and the incidence of earthquakes of Magnitude 7 and above. The rotation speed of the planet increases and decreases over periods of years and decades. From their research, the earth scientists say that there's an substantial increase in the number of powerful earthquakes around the world five years after the Earth attains a peak in its spin speed and enters a period of slow down. The difference in day length is tiny but it is enough, say the researchers, to trigger already stressed faults in the crust to move sooner than later. In the year that the Soviet Union launched Sputnik into orbit, the UK launched its own rocket into the Space Race. 1957 saw the launch of the first Skylark space rocket. Inside Science talks to two veterans of the Skylark programme - Professors John Zarnecki and Ken Pounds - who cut their space research teeth with some of the 440 launches. The Science Museum in London is staging a Skylark exhibition in celebration. Francis Galton was one of the UK's most influential 19th century scientists and laid important methodological foundations for genetics and other fields of science today. But he was also a racist and leading proponent of eugenics. Adam discusses Galton's legacy with historian Subhadra Das of University College London and clinical geneticist Han Brunner of the Maastricht University Medical Centre in the Netherlands. Both guests attended a meeting of the Galton Institute in London which brought together researchers of many disciplines to discuss the bad and the good in Francis Galton's legacy. Producer: Andrew Luck-Baker.

Researchers in Italy and Germany have saved the life of a boy with a life threatening genetic skin disease, using a combination of stem cell and gene therapy. 7 year old Hassan had lost 60% of his protective epidermis because of the condition, junctional epidermolysis bullosa. The severe blistering and consequent bacterial infections put his life in imminent danger. In a final attempt to save him, the scientists took a small area of unblistered epidermis from his body, separated the constituent skin cells and then engineered them with a normal version of the gene that was malfunctioning in Hassan's body. Sheets of healthy epidermis of an area of about one square metre were then grown in culture, and then grafted onto 80% of his body. Hassan is now living a normal life, back at school, playing football. Lead researcher Michele de Luca describes the remarkable recovery and Fiona Watt, director of the Centre for Stem Cell and Regenerative Medicine at Kings College London, explains how the procedure worked. Scientists at the University of York are investigating medieval livestock farming through the study of the 1,000 year old York Gospels manuscript: not by reading it but by extracting proteins and DNA from its animal skin parchment pages. Inside Science listener and Middle Eastern archaeologist Melissa Sharp takes the programme to task for suggesting that anyone can now use publically available sonar and satellite data to search for shipwrecks and other archaeological sites. It opens up the world's ancient and not so ancient heritage to looters, she says. Since the University of Cambridge made Stephen Hawkings 1966 PhD thesis free to view and download last month, more than a million people have at least looked at it. Adam Rutherford talks to cosmologist Andrew Pontzen, biologist Matthew Cobb and neuroscientist Sophie Scott about the record-breaking thesis and asks whose first research project they'd like to download. Producer: Andrew Luck-Baker

Adam Rutherford talks to researchers on a major global study that aimed to quantify how climate change has already damaged the health of millions of people. Hugh Montgomery is the co-chair of the Lancet Countdown report and says that climate change is the largest single threat to global health. Climate scientist Peter Cox talks about his stark findings on the increase in the number of vulnerable people exposed to heat waves between now and the turn of the century. We hear anecdotes and concerns from listeners following our item last week on the catastrophic decline in flying insects in the last quarter century and the disappearance of moth snow storms. What can the social lives and brains of whales and dolphins tell us about the evolution of our species cognitive capacities and white matter? Adam talks to Susanne Shultz of the University of Manchester. Everyone's favourite indoor firework, the Pharoah's Serpent, is under scientific scrutiny from chemists Tom Miller and Andrea Sella at University College London.

The total biomass of flying insects in the environment has decreased by 75% in the last quarter of a century. That's the conclusion of research published at the end of last week in the journal PLOS One. The discovery, made in Germany, has shocked many, but should we in the UK be worried too? The answer is yes, according to Adam Rutherford's guests Dave Goulson, professor of biology at the University of Sussex, and Michael McCarthy, environmental journalist and author of 'The Moth Snow Storm.' The speed and ease of precise infection diagnosis could be transformed by synthetic biologists at Imperial College, London. Paul Freemont tells Adam about a simple DNA biosensor that turns green in the presence of a pneumonia-causing bacterium that is a particular problem for people with Cystic Fibrosis. He adds that the technology is adaptable to any kind of bacteria and may also aid efforts to curb the spread of antibiotic resistance. When dogs know you are looking at them, they ramp up the expressiveness of their faces. Marnie Chesterton visits the Dog Cognition Centre at the University of Portsmouth to talk to the researchers who made this discovery, and to meet Jimmy the Staffy. Palaeontologists at the University of Bristol have figured out the colour patterning on a dinosaur that lived 120 million years ago. Sinosauropteryx was a small feathered dinosaur. Two spectacular fossils of it were found in northeast China. The specimens are so well preserved that remnants of pigment remain in the feathers. This allows Jakob Vinter and colleagues to see that Sinosauropteryx was reddish brown in colour, with light stripes on its tail, light and dark counter-shading on its body and a dashing bandit-style face mask. Producer: Andrew Luck-Baker.

Adam Rutherford talks to astrophysicists about the astronomical discovery of the year, if not the last couple of decades: the collision of two neutron stars and the cosmic gold-forging aftermath. The discovery of this long-hypothesized event on 17th August came from the much awaited marriage of the capabilities of the gravitational wave detectors LIGO and Virgo with those of ground-based and space-based telescopes. Samaya Nissanke of Radboud University, Sheila Rowan of the University of Glasgow and Nial Tanvir of the University of Leicester take Inside Science through the story. What made the infamous 1883 eruption of Krakatoa so devastating? Roland Pease meets the earth scientists trying to answer the question by recreating in the lab the conditions under the volcano prior to the eruption. Following a temperature-related faux pas by Adam in the last episode, Michael de Podesta of the National Physical Laboratory explains the difference between Celsius and Centigrade. Producer: Andrew Luck-Baker.

Gareth Mitchell talks to Gillian Foulger of Durham University about HiQuake, the world's largest database of human-induced earthquakes. Professor Foulger and her colleagues have so far compiled close to 750 seismic events for which there are reasonable cases to be made for anthropogenic triggers. Triggers include mining operations, fossil fuel extraction, reservoir filling, skyscraper construction and tunnelling. Among the surprises is the fact that the US state of Oklahoma is more seismically active than California because of quakes and tremors set off by the local oil and gas industry. The theory of plate tectonics is 50 years old. It's as fundamental to understanding the Earth as evolution by natural selection is to understanding life. Roland Pease meets geologists such as Dan McKenzie, John Dewey and Xavier Le Pichon who played key roles in proving the hypothesis in the late 1960s. The United States has removed more than half of its diplomats from its embassy in Havana, Cuba. A signficant number of staff have complained of ailments such as hearing loss, dizziness, headaches and nausea, and there has been speculation that some kind of sonic or acoustic weapon might be responsible. Trevor Cox, professor of acoustic engineering at the University of Salford, discusses the likelihood with Gareth. Stanford University's Tom Mullaney is the author of 'The Chinese Typewriter: A History'. He talks to Gareth about the great engineering and linguistic challenge in the 19th and 20th centuries of getting the Chinese language onto a table top machine. The survival of the ancient language or China's entry into the modern world depended on the success of numerous inventors. In fact one consequence was the development of predictive text in the Chinese IT world long before it appeared in the West. Note: In the podcast version of this programme, there is an additional item on new research on the role of the world's botanical gardens in global plant conservation. One of the scientists involved, Dr Paul Smith of Botanical Gardens Conservation International, tells Gareth that there's good news about these institutions' contributions and there are areas where there is room for improvement. Producer: Andrew Luck-Baker

The gravitational waves produced by two massive black holes colliding have for the first time been detected by three gravitational wave detectors. Professor Sheila Rowan of the University of Glasgow explains the importance of this new three way observation. The World Health organisation reports that there are too few new candidate antibiotics in the development pipelines to replace those becoming obsolete through the rapid spread of antibiotic resistance. Professor Willem van Shaik of the University of Birmingham and pharma-biotech analyst Dr Jack Scannell discuss where the problems and solutions might lie. Could bacteria recycle all of our waste? Waste disposal is a growing concern as nations run out of space and ecosystems are increasingly polluted. Microorganisms may hold the key for turning household waste into biodegradable plastic and perhaps one day even into food and basic chemical feedstocks. Hans Vesterhoff, Professor of Systems Biology at Amsterdam University is developing microbial networks with the aim of converting all carbon-based waste into useful or edible stuff. AI and Opera: Prof Luc Steels, an AI and language researcher at the Institute for Advanced Studies of Catalonia is also a composer. He has just had his new opera premiered. With a libretto written by a neuropsychiatrist colleague, the opera 'Fausto' is a re-telling of the Faust story. It explores the dangers and flawed thinking of silicon-based transhumanism. In the opera, the Faust character is a social media-obsessed hipster and Mephistopheles is a malevolent AI in the cloud. In a twist on the original, Fausto trades his body rather than his soul so that he can be uploaded and reunited with his lover in the cloud.

After last week's Inside Science's edition devoted to Cassini ended, the Cassini spaceship plunged into the atmosphere of Saturn, and became part of the planet it studied. But the project lives on, as the data and photos generated by Cassini right up until contact was lost will be studied and scrutinised for years to come. Linda Spilker is the Project Scientist for the Cassini mission. Adam Rutherford spoke to her to find out what was captured in the last few moments of Cassini's closest and fatal encounter with the ringed planet. The House of Commons has announced its Science and Technology Select Committee - the body of MPs that holds the Government to account on scientific matters, and offers advice on scientific issues of the day. Some controversy has followed, concerning the scientific credentials and the gender imbalance of the committee make-up so far. Norman Lamb, MP for North Norfolk was elected chair of the committee, and he came into the Inside Science studio to discuss the committee selection and its future ambitions. This week was the 60th anniversary of one of the greatest conceptual leaps in all biology, made by Crick at a lecture at University College London. Matthew Cobb, biologist and historian from Manchester University, who's written a new account of the lecture, discusses its fundamental significance. It has long been suggested that there's something about the acoustics of a cave that correlates with the location of motifs and sometimes paintings on the walls.Bruno Fazenda is an acoustic scientist at the University of Salford, and reveals how he went into the caves to conduct the first methodical study of this theory by listening to the past.

As Cassini's epic journey to Saturn finally ends tonight, Adam Rutherford celebrates the incredible discoveries of a mission that has changed the way we see our solar system. BBC Science Correspondent Jonathan Amos is at Mission Control in Pasadena as scientists assemble to witness the final few hours of the Saturnian observations beforeCassini completes its death dive into the planet. We also hear from key scientists who've played a role in capturing and interpreting the multitude of data from the last 12 years. With contributions from Michele Dougherty, Professor of space physics at Imperial College Robert Brown, Professor Planetary surface processes Arizona University Carl Murray, Professor of Astronomy, Queen Mary,University of London Ellen Stofan, former chief NASA scientist Producer Adrian Washbourne.

The Democratic People's Republic of Korea claims to have successfully tested a thermonuclear weapon, a hydrogen bomb. Tom Plant, director of Proliferation and Nuclear Policy at the Royal United Services Institute, talks to Adam Rutherford about how the boast might be proved by monitoring technology around the world. How will marine life respond to warming of the seas around Antarctica this century? Dramatically, according to the results of the most realistic attempt so far to warm the sea bed to temperatures predicted for the coming decades. The British Antarctic Survey installed gently heated panels at 12 metres depth off the West Antarctic coast to mimic rock surfaces and then over 9 months monitored how marine creatures colonised and grew on them. All creatures flourished on panels at 1 degree C above today's chilly waters and in fact grew astonishingly quickly on them. But a 2 degree increase saw some continue to flourish vigorously but many species fail. Experiment mastermind Lloyd Peck tells Adam what the findings may mean, and describes the extraordinary cold water diving skills that made the experiment a success. 'I contain Multitudes' is shortlisted for the Royal Society Insight Investment Science Book Prize this year. Its subject is the microbiome - the trillions of benign , friendly and not so friendly bacteria which inhabit our bodies and those of all other animals. For 30 years, Cambridge University zoologists have studied the evolutionary arms race between the cuckoo and the reed warbler that rears the cheating bird's offspring. They have figured out many of the deceptions and counter-tactics adopted by the two co-evolving species. The latest revelation concerns the strange chuckling call which the female cuckoo makes after laying her egg in the warbler's nest. Jenny York describes the experiments which show that the cuckoo is mimicking a predatory sparrow hawk which distracts the warblers and makes them much more likely to not recognise her egg as something they should reject from the nest.

Last weekend a chemical ‘haze’ on the East Sussex coast saw 150 people needing hospital treatment after something in the air led to streaming eyes, sore throats and nausea. Leading theories so far include a chemical spill from shipping in the English channel, a localised spike in ozone levels and an algal bloom, where algae suddenly proliferate and release harmful gasses. Dr Simon Boxall of the National Oceanography Centre at the University of Southampton tells Gareth Mitchell why he’s favouring the algal bloom theory. We know about extinct species from fossils in rocks. But in the future there will be techno-fossils too, evidence of our civilisation. Katie Kropshofer has been finding out from Professors Jan Zalasiewicz and Sarah Gabbot of the University of Leicester what we’re leaving for the hypothetical geologists of the future. Neuroscientist Joseph Jebelli's book, In Pursuit of Memory: The Fight Against Alzheimer's, is the one of the six titles on the shortlist of the Royal Society Insight Investment Science Book Prize. He explains to Gareth Mitchell that it was his grandfather's development of the condition that made him interested in Alzheimer’s. The Big Wasp Survey is a citizen project to trap wasps and send them off to teams at the University of Gloucester and University College London, so that scientists can then learn more about the distribution of different species around this land. One of the organisers, entomologist and professor of Science Communication at the University of Gloucester Adam Hart, talks to Gareth about why these unpopular insects are ecologically valuable.

Once again, the ethical side of fully autonomous weapons has been raised, this time by over 100 leading robotics experts, including Elon Musk of SpaceX and Tesla, and Mustafa Suleyman of DeepMind. They have sent an open letter to the United Nations urging them to take action in order to prevent the development of "killer robots". The letter says "lethal autonomous" technology is a "Pandora's box", once opened it will be very difficult to close - they have called for a ban on the use of AI in managing weaponry. Gareth asks AI expert, Professor Peter Bentley from University College London, if this is the right approach or is this just an attempt to delay the inevitable? When a paper titled "Fantastic Beasts and Why to Conserve Them" is printed in the journal Oryx, we had to take a closer look. Far more than a publicity stunt, this work by George Holmes, an expert in conservation and society at the University of Leeds, covers an important point. It explores the dangers of neglecting local beliefs, myths and superstitions about the natural world, and animals in particular, when trying to come up with conservation strategies. Cordelia Fine is a professor of the history and philosophy of science at the University of Melbourne. She is the third shortlisted author of the Royal Society Insight Investment Science Book Prize. Her book "Testosterone Rex" explores the science behind gender. She argues that testosterone isn't necessarily the basis for masculinity and that there is so much more to gender than merely our biological sex. 200 years ago, taxidermy was a crucial part of zoological teaching and research, and in the days before BBC wildlife films, often the only way that many people could see strange and exotic wildlife from other lands. Lots of those early specimens are incredibly valuable, and can still be found in museums around the world, although being so old they are often in need of urgent repair. Usually this happens out of sight behind the scenes, but not so at the Grant Museum of Zoology in London, which has been doing its conservation live in the gallery for all to see, to draw attention to the art and science of taxidermy. Some of the more serious repairs get sent to taxidermy conservator Lucie Mascord in Lancashire. Produced by Fiona Roberts Presented by Gareth Mitchell.

Not so much hiding in plain sight, but tucked under the ice-sheet in Antarctica are 91 volcanoes. This adds to the 47 volcanoes already known on the continent. After a graduate student posed the question,"are there any volcanoes in Western Antarctica?", Dr Robert Bingham, and colleagues, at Edinburgh University, scoured the satellite and database records to find the volcanoes. This huge region is likely to dwarf that of East Africa's volcanic ridge, which is currently the most volcano-dense region on Earth. Journalist Mark O'Connell is the second of our Royal Society Insight Investment Science Book Prize 2017 nominees. His broad-minded, yet sceptical look at the world of 'transhumanism', "To be a Machine: Adventures Among Cyborgs, Utopians, Hackers, and the Futurists Solving the Modest Problem of Death", questions how and why some of us are looking to use technology to fundamentally change the human condition. On Monday 21st of August 2017, some of the United States will go dark. This is the first total solar eclipse, visible from coast to coast in the US for 99 years. Gareth gets excited with veteran eclipse watchers, David Baron and Jackie Beucher. On the 20th of August 1977, NASA's probe Voyager 2 launched. This was quickly followed two weeks later by the launch of Voyager 1 (which was on a faster trajectory). Since then the two spacecraft have been exploring our Solar System, the Heliosphere and interstellar space. Surpassing all expectations, the probes have taught us so much about our planets, their moons and beyond. Gareth looks back at the highlights with the Voyager mission's chief scientist, Professor Ed Stone, in a celebration of the 40 year mission. Produced by Fiona Roberts Presented by Gareth Mitchell.

The current heat wave in Europe is proving deadly. High day and night temperatures, coupled with high humidity, can be a very dangerous combination. A new study has calculated the risk of deadly heat on a global basis, and shown that between 48% and 74% of the world's population will be subjected to life-threatening heat and humidity for at least 20 days a year. Ed Hawkins, Professor of Climate Science at the University of Reading, discusses the findings. Gareth also asks BBC weatherman, Darren Betts, whether the recent wave of climate trend animations, or gifs, doing the rounds on social media, are a helpful tool in communicating climate change risks. Professor of Mathematics, Eugenia Cheng, is one of the shortlisted authors for the Royal Society Insight Investment Science Book Prize 2017. She talks Gareth through the inspiration for her book "Beyond Infinity: An expedition to the Outer Limits of the Mathematical Universe". The UK Government announced last week that it was aspiring to remove all petrol and diesel vehicles from roads by 2040. Current battery technology relies on lithium-ion batteries. Are lithium, and the other metals required for batteries, sustainable for a totally electric transport system? And do they have the charge capacity to make them a reliable alternative to fossil fuels? Dr Billy Wu, of the Dyson School of Design Engineering at Imperial College London, goes through the alternatives and the next generation of battery technology. To mark the 200th anniversary of the birth of one of Victorian Britain's most important scientists, Joseph Hooker (1817-1911), Kew Royal Botanic Gardens is holding an exhibition titled Joseph Dalton Hooker: Putting plants in their place. It's a fascinating selection of his photographs, journals and paintings. Gareth is taken on a tour by the curators - historian Professor Jim Endersby of the University of Sussex and Galleries and Exhibitions Leader at RBG Kew, Maria Devaney. They explain how as a tireless traveller and plant collector, Hooker was the founder of modern botanical classification and a close friend of Charles Darwin. Produced by Fiona Roberts Presented by Gareth Mitchell.

Hypertrophic cardiomyopathy is the heart condition that can lead to seemingly super-fit athletes collapsing with heart failure. It affects one in 500 people, and is a heritable disorder. Scientists using the precise gene-editing technique, Crispr CAS 9, have identified one of the genes responsible for the disease and 'fixed' it. This is in very early stage human embryos, prior to implantation. Dr. Fredrik Lanner at the Karolinska institute, is a leader in this field and he describes the work as purely at the experimental stages, but the team have managed to overcome various issues with the technique. Despite the obvious benefits of being an astronaut... exploring new worlds, seeing Earth from space, and of course the glory and fame, it can take a real toll on the body. Astronauts' skeletons and muscles deteriorate in zero gravity, their immune system weakens, and they experience nasal congestion and sleep disturbance. Many symptoms persists once they're back on Earth. But, there's another to add to the list, space flight-associated neuro-ocular syndrome or SANS. Ophthalmologist at Houston Methodist Hospital, Dr Andrew Lee explains that the build-up of fluid in the brain can squeeze the eye and optic nerve and lead to visual disturbance and even vision loss. The shortlist for the Royal Society Insight Investment Science Book Prize 2017 has just been announced. Adam pesters judge Claudia Hammond for the name of the winner (she doesn't tell!) and discusses the criteria for this £25,000 prestigious award. The top 6 books will be featured over the next 6 weeks on BBC Inside Science. Sexual selection - who you decide to have babies with - is usually decided at the dating stage. But the choice does not have to stop at copulation. Post-mating sexual selection is a thing. Mechanisms such as sperm competition, and cryptic female choice, can happen after sex, but before the sperm fertilises the egg. It's not just an internal thing either, it happens in 'external fertilizers', where eggs are laid, and then fertilized by the male sperm outside the female's body, like come fish do in water. Professor Neil Gemmell, at the University of Otago in Dunedin in New Zealand, has been studying just such processes in Chinook salmon. His findings are surprising and could inform us about human reproduction and fertility. Produced by Fiona Roberts.

News that the Marine Stewardship Council has reopened the North Sea cod fishery is met by some concern from marine biologist Professor Callum Roberts at the University of York. He says, this may be good news for cod and cod fishermen, but other marine species getting caught up in the drag nets may not be so capable of bouncing back. In a report out this week, the UK Government announced they are funding £246 million for major changes to the way electricity is produced and stored. New rules will make it easier for people to generate their own power with solar panels, and store it in batteries. But do we have the technology to make it work in a cost effective way? Steven Harris, a consultant in sustainable energy, thinks we'll soon have smart domestic appliances in our homes which better manage the fluctuating supply and demand for power. Expert in energy systems, at the University of Newcastle, Professor Phil Taylor, is researching the next generation of smart appliances and domestic storage batteries. A new study reports that 69% of Brits feel they have lost touch with nature. Dr. Rachel Bragg, at the Green Exercise Research Unit at the University of Essex and Care Farming UK, unpicks the anecdotal evidence from the facts and explores why a connection with the natural world is so important, why the connection is being broken and what we need to do about it. Professor of Extragalactic Astronomy at the University of Bath, Carole Mundell, explains how she and other astronomers captured the most complete picture yet of the most powerful type of explosion in the universe - Gamma Ray Bursts. These short-lived bursts of the most energetic form of light, shine hundreds of times brighter than a supernova and trillions of times brighter than our sun.

Should our genomes be private? Professors Tim Hubbard and Nils Hoppe join Adam Rutherford to discuss concerns about data security and privacy of our genetic data. Once our DNA has been extracted, sequenced and stored as a digital file, what is done with it, who gets to see it and what say do we have in all this? Back in the 1950's at the dawn of the new plastic age, its everlasting properties were a major selling point. Now, we're dealing with escalating plastic pollution and bulging landfill. But how much plastic are we dealing with? Dr. Roland Geyer has calculated the production, use and fate of all plastics ever made. Chimpanzees are very communicative animals: they tend to use gestures foremost with vocalisation just to emphasise the flick of a wrist or a stretch of the hand. In an attempt to get a grasp on why, and how, we humans made the shift from gesture-led communication to talking, we need to see how well we can decipher our ape relatives. A new online study called the 'Great Ape Dictionary' wants you to have a go. The bottom of our seas remains a mysterious other world. Yet, adventuring into the deep depths of the ocean is a major challenge, which is probably why only 5% of it has ever been explored - even though it covers more than 70% of our planet. So to start learning more about our own planet, the Shell Ocean Discovery XPRIZE is awarding a total of $7 million to teams that develop autonomous, unmanned vehicles to map and image the bottom of the seas. Dr Jyotika Virmani tells Adam why ocean exploration is so important, and why it tends to take a backseat to adventuring into space. Presented by Adam Rutherford Produced by Fiona Roberts.

What can genome science do for you? Chief Medical officer Dame Sally Davies recently published her annual report, issuing a plea for a revolution in the use of genetic information in the NHS. She wants DNA tests to be as routine as biopsies or blood tests. Adam chats to geneticist Ewan Birney, head of the European Bioinformatics Institute in Hinxton, about the potential uses and limitations of genetic testing. Pugs are set to become Britain's most popular breed in the next couple of years. Together with similar dogs, like bulldogs and Frenchies, they are classed 'brachycephalic', having short snouts and compact skulls which makes them susceptible to a breathing problems. Veterinary surgeon Jane Ladlow has studied 1,000 dogs to improve their health today and in future generations. Reporter Graihagh Jackson went to visit the team at Cambridge Veterinary School. To mark the forthcoming 200th anniversary of the publication of Frankenstein, a new edition has been created especially for scientists and engineers. Adam talks to editor David Guston, from Arizona State University about the lessons this cautionary tale contains for science today. Presenter: Adam Rutherford Producer: Michelle Martin.

The results of the first large-scale field study looking at neonicotinoid pesticides and their impact on bees has caused controversy. It was carried out by the Centre for Ecology and Hydrology (CEH) and commissioned and funded by the agricultural chemical companies Syngenta and Bayer. However, both companies have expressed dissatisfaction with the paper. Adam Rutherford talks to Dr Peter Campbell from Syngenta and Dr Ben Woodcock from CEH about the results. In a separate project, beekeepers have been trying to improve hive health by breeding 'hygienic bees'. These nifty insects love to keep their homes clean and free from disease, improving colony numbers and reducing the need to use antibiotics. Reporter Rory Galloway embarks on some fieldwork at the University of Sussex, with Luciano Scandin, Honeybee Research Facility Manager and Francis Ratnieks, Professor of Apiculture. What happens when you rap inside an MRI scanner? Neuroscientist Sophie Scott wanted to find out. She's been making movies of the internal workings of some extraordinary voice boxes, owned by beatboxers, opera singers and rappers, like biochemist Alex Lathbridge aka Thermoflynamics. Presenter: Adam Rutherford Researcher: Caroline Steel Producer: Michelle Martin.

Teams from all over the world have been looking at the differences between male and female mice. They've assessed hundreds of characteristics, from weight changes to cholesterol to blood chemistry. The surprising results show huge differences between the sexes, which have great repercussions for drug development which mostly uses male mice, and humans, for testing. Medicines may be less effective in females, or have greater side-effects, due to the extent of genetic differences being found between the sexes. Adam talks to one of the authors, Prof Judith Mank from University College London. Three global engineering technologies are in the running for this year's coveted MacRobert Award, the UK's top innovation prize. Adam Rutherford talks to judge Dr Dame Sue Ion to find out more about each of the finalists - Darktrace, Raspberry Pi and Vision RT. Urban bats are getting smart - sensors newly installed at the Queen Elizabeth Olympic Park in Stratford are using machine learning algorithms to recognise and record the different colonies that emerge after dark. One in five mammal species are bats, and they are often used as an indicator to measure the health of our environment. BBC Science reporter Helen Briggs talks to Prof Kate Jones and the team involved in creating and installing these hi-tech bat phones. Anthony Warner is a chef. And he's angry. With a background in biochemistry he's pledged to fight fad diets, bogus nutritional advice and celebrity food nonsense wherever he finds it. From Clean Eating to the Paleo Diet, he busts some diet myths for us, and explains why we've unfairly demonised ingredients like gluten. Presenter: Adam Rutherford Assistant Producer: Caroline Steel Producer: Michelle Martin.

The Leverhulme Research Centre for Forensic Science at the University of Dundee has expanded to test new psychoactive substances. Adam Rutherford talks to Professors Sue Black and Niamh Nic Daeid, who jointly run the Centre, about how they can keep up with the many new illegal drugs coming onto the market and about how they intend to modernise forensics. 2017 is the centenary of the publication of On Growth and Form, the book by D'Arcy Thompson that influenced many people from mathematical biologists to architects. Adam discusses the man and the book with Matthew Jarrron in the D'Arcy Thompson Museum at the University of Dundee. Astrophysicist Sheila Rowan has been the Chief Science Adviser to the Scottish Government for just over a year. Adam asks her about the role and how she deals with controversial issues such as GM crops. And Aaron Davis of Kew Gardens explains the impact of climate change on coffee growing in Ethiopia.

Applying scientific techniques to reduce fire risk in tall buildings. We look at practical measures to prevent building fires and also how science can improve evacuation plans. Modeling the brain with maths. new research using multidimensional models is helping researchers understand the levels of complexity in brain function. Sexism in science, its as old as...science. We look at how sex bias has influenced the outcome of scientific research throughout history. And also look at how science itself is changing as opportunities for women to pursue scientific careers increase. And a unique study which turns recordings from police body cameras into empirical data that can be used to assess and improve police interactions with the public.

Early human fossils from Morocco suggest our ancestors walked the earth much earlier than previously thought. Human ancestral fossils from the area were first discovered in the 1960's, but now a re-examination of these and more recent finds suggests they are from an early form of us - Homo sapiens - living in the area around 300,000 years ago. We have news of a one in a million stellar observation: light bending around a distant star. This is the first time the phenomenon has been observed outside our solar system, and is further proof of Einstein's theory of General Relativity. It involved measurements millions of miles away and many times smaller than the width of a human hair. Gold mining is a highly polluting process involving toxic chemicals. Marnie Chesterton visits a Scottish gold mine and looks at attempts to make the extraction of gold more environmentally friendly by replacing the toxic chemicals with ingredients more commonly found in vitamins and natural fertilisers. And US President Trump has announced his intention to pullout of the Paris climate agreement. We look at the implications of the decision for global emissions reduction.

Adam Rutherford discusses the relationship between basic and applied scientific research with guests at the Hay Festival. Adam is joined by the Astronomer Royal, Lord Martin Rees, physicist Professor Robbert Dijkgraaf, the director of the Institute for Advanced Studies at Princeton University and author of a new essay introducing On the Usefulness of Useless Knowledge, behavioural psychologist Professor Theresa Marteau of Cambridge University and geneticist and writer Professor Steve Jones of University College London.

The superior performance of Sherpa guides on Mountain Everest is legendary. New findings reveal how their bodies make the most of low oxygen levels at high altitude. Presenter Gareth Mitchell also talks to the Mexican biologist heading a last ditch attempt to save the world's most endangered marine mammal - a small porpoise called vaquita. There are fewer than 30 animals left, all of them in the Gulf of California. The plan is to capture up to half of them and move them to a safe haven in the Gulf, away from the illegal fishing nets that have been trapping and drowning them. Key players in the plan are US Navy dolphins, trained to find and follow the vaquitas so the scientists can catch and move them. The idea is to keep the porpoises in a protected bay until the illegal fishing threat has been tackled. Also in the programme, white hot lavas and reporter Roland Pease asks whether quantum computing is finally coming of age.

Adam Rutherford goes the pathology archive of Great Ormond Street Hospital in London to hear how tumour samples from child patients about one hundred years ago may improve the diagnosis and treatment of very rare cancers in children today. He meets cancer geneticist Sam Behjati of the Wellcome Trust Sanger Institute and Great Ormond Street pathologist Neil Sebire in the hospital's basement archive. Africa now has its first radio telescope outside South Africa. It is located in Ghana near the capital Accra. The telescope is in fact a defunct telecoms satellite dish which was spotted on Google Earth images and then re-purposed for cutting edge astrophysics. It is hoped the dish will be the founding instrument of a pan African network of radio telescopes scrutinising exotic celestial objects in the skies above the continent. South African science journalist Sarah Wilds tells the story of how the Ghanaian dish was found and converted. Nano-engineers in California have created a device 100 times thinner than a human hair which they have used to measure the turbulence created by swimming microbes and record the sounds of heart cells contracting. Don Sirbuly is the professor of nano-engineering at the University of California San Diego who led the team. A spectacular new whale fossil unearthed Peru is the oldest known member of the evolutionary branch which gave rise to the giant filter-feeding baleen whales of today. The 36 million year old fossil provides evidence for how ancestral whales transitioned from capturing prey with their teeth to filter-feeding with baleen fibres. They may gone through a period of sucking prey from the sea bed.

Classical music fans will know well the legendary violins made by the likes of Stradivarius and Guarneri in the 17th and 18th century. But new acoustical research has found that concert goers rated the music of new fiddles higher than that from old and revered Italian violins. Dr Claudia Fritz of the Pierre and Marie Curie University in Paris explains how she did this study and what she found. Virtuoso soloist Tasmin Little plays her 260 year old Italian instrument for presenter Adam Rutherford and offers her thoughts on the findings. Adam also hears about personality and social cliques in great tits in Oxfordshire, and social networks and disease in Japanese snow monkeys. Adam chats with Leicester University geneticist Turi King and artists Ruth Singer and Gillian McFarland about their collaborative project to explore DNA through art.

Adam Rutherford talks to neuroscientist Molly Crockett about moral decision-making in the brain. She combined brain scanning with a test involving money and electric shocks. Geoff Marsh reports from Japan where stem cell research appears to be bringing regenerative medicine for a common cause of blindness ever closer. A team at the Max Planck Institute for Evolutionary Anthropology has pulled off another triumph in the study of ancient human DNA. Viviane Slon explains how they've extracted DNA of extinct species of humans from the soil in caves across Europe and Russia. Adam discusses the significance with Ian Barnes, ancient DNA specialist at the Natural History Museum in London. Dan Friess of the National University of Singapore studies mangrove forests around the coasts of tropical Pacific and Indian ocean countries. This kind of forest has turned out to store much more carbon than even rainforests, as measured by the hectare. Dr Friess talks about carbon counting in mangroves and how this research may save the forests from further destruction.

Controversy has followed the remains of a new species of human, Homo naledi, since it was described in 2015. Buried deep in a South African cave, its primitive features led scientists to believe it was up to three million years old. This week it's been revealed that this estimate was wrong. New dating evidence suggests the skeletons are only 200 000 to 300 000 years old and that means they may have lived alongside other homo species. Previously, humans were thought to have travelled to America via a land bridge between eastern Siberia and modern day Alaska, somewhere between 17 000 - 40 000 years ago when sea levels were lower than they are today. Researchers from the San Diego Natural History Museum now present evidence that suggests this transition could have been much earlier - nearly 100 000 years earlier. Adam talked to Chris Stringer, researcher in human evolution at the Natural History Museum in London, to unpick the evidence. Dark matter is a mystery that has evaded scientists for decades. Now the biggest and most sensitive detector is being built in South Dakota and scientists believe the Lux-Zeppelin experiment will soon be able to detect one of the candidates for dark matter, the elusive particle known as a weakly interacting massive particle (WIMP). Graihagh Jackson got a sneak peak of the key components, including the 'eyes' of the detector, before they're sent off for installation. Adam Rutherford talks to cosmologist Carlos Frenk from the University of Durham and learns of an alternative theory to describe this mysterious dark matter - a whole new dark sector. This sector contains a vast range of different dark particles, from photons to bosons, that could interact with normal particles.

The Cassini-Huygens mission has been monumental for science. For thirteen years the probe has gathered data on Saturn, revealing more about the gas giant than we have ever known before. But now, Cassini is running out of fuel. Adam Rutherford talks to Professor Michele Dougherty of Imperial College about the plans for Cassini's spectacular end, which will be to burn up in Saturn's atmosphere later this year. The descent begins this week and Cassini will collect exciting new data until the end. Next week, Theresa May will unveil her plans to kerb air pollution and it is believed that some diesel drivers could be paid up to £2,000 to trade in their vehicles. Diesel cars emit nitrogen oxides - a pollutant that has been linked to nearly 12,000 UK deaths in 2013. This is the second highest in Europe after Italy. However, this isn't the first scrappage scheme to be brought in. Philippa Oldham from the Institution of Mechanical Engineers and Adam discuss the merits and pitfalls of an initiative like this. Thousands of balloons are launched every day to measure temperature, pressure and humidity of the air. Kerri Nicoll from the University of Reading wants to add cheap, volcanic ash sensors to these balloons which are going up anyway. This could vastly improve the limited information we currently have on volcanic eruptions, allowing us to quickly see rises in ash particles and therefore improve ash cloud forecasting. Many of the world's volcanoes aren't monitored but a new technology from the University of Leeds should mean that scientists can keep track of all 1,500 them by the end of the year. The technology involves monitoring changes in ground deformation from satellites in space, which will give clues as to whether a volcano is about to erupt. For those living near unmonitored volcanoes, this could provide an early warning system and save their lives.

23andMe is one of the biggest providers of home genetic testing kits and if you live in the UK, it's the only one that also includes various genetic analyses relevant not just to ancestry, but also to health. After a previous ban, the Food and Drug Administration for the first time approved marketing of the 23andMe Genetic Health Risk tests for diseases in the US. Adam Rutherford talks to geneticist Professor Matthew Cobb of the University of Manchester and to medical ethicist Dr Sarah Chan of the University of Edinburgh about how useful this genetic information can be and about who owns the data. New research published this week has revealed something really quite bizarre about our own genomes: that we can survive normally with a considerable number of dysfunctional genes. We've got around 20,000 genes, and you might think that you need them all, as when they don't work, they could lead to a serious health condition. But from a study of more than 10,000 people from Pakistan more than 1300 mutations were found to have no effect on their health. Geneticist Robert Plenge explains the research. The Great Barrier Reef has taken another huge hit with a mass bleaching event occurring a second year in a row. Over two thirds of the reef is now seriously damaged. Professor Jorg Wiedenmann of the University of Southampton explains that if bleaching events continue to happen at this rate, the world's largest coral reef will never recover.

Adam Rutherford examines a new study published this week which reveals how a megaflood and giant waterfalls severed our connection to what is now France, resulting in the creation of island Britain and the watery moat of the English Channel. Jenny Collier of Imperial College London uncovers the ancient evidence dating back 450 000 years ago. The dream of unbroken sleep is a complex interaction between our environment and our genes, and new research is a step towards understanding the genetics of sleeping patterns. Jason Gerstner of Washington State University discusses his isolation of a gene that seems to play a crucial role in sleep across a number of species including humans. Turi King played a pivotal role in the identification of Richard III from bones discovered in a Leicester car park She's now involved in another infamous cold case - that of Jack the Ripper. Her interest is in the last of his five canonical victims, known as Mary Kelly, and she's authored a commissioned report on the possibility of identifying the body of Mary Kelly using DNA. And Paul Smith from Gardens Conservation International discusses the new Global Tree Survey - the biggest and the most comprehensive database of all the trees in the world - accumulated from 500 papers, and nearly four centuries of dendrology. Producer Adrian Washbourne.

Following yesterday's US House Committee on Science,Space,and Technology's controversial hearing on scientific method and climate change, Adam Rutherford meets atmospheric scientist Professor Michael Mann after he emerged from the heated debate and who's just published a new paper suggesting a direct link between extreme weather and greenhouse gases via a particular behaviour of the jet stream across the northern hemisphereHow has intelligence evolved? For over 2 decades the idea has prevailed that primate brain size and intelligence has been driven mainly by complex social hierarchies. But a new study by Alex DeCascien of New York University suggests that diet is a better predictor of brain size. This month is the 6th anniversary of the earthquake and tsunami that devastated much of Japan's coastline. Roland Pease reports on new research that aims to embrace uncertainty to improve quake forecastingAnd we hear how you can join in the search for the missing mysterious 9th planet of our solar system. Adam Rutherford hears from astronomer Brad Tucker on Walkabout at the Mount Stromlo Observatory in New South WalesProducer: Adrian Washbourne.

The recent Rosetta mission to image and land a probe on a comet was an astounding achievement. Rosetta took thousands of photos mapping the entire surface of comet 67P/Churyumov-Gerasimenko , as it dramatically changed over 2 years. This week analysis of 18000 67P pictures are out of the shade and into the sunlight. Adam Rutherford talks to study leader Raamy El Maary on the intriguing insights and what they suggests about the evolution of comets as they pass through our solar system.And while no-one has any doubt that volcanoes are extremely dangerous forces of nature, Science correspondent Rebecca Morelle was caught in an unusual and terrifying eruption last week. She tells BBC Inside Science the perils of reporting up close from the side of Etna and the rare kind of eruptions that are unique to snowy volcanoes.What are our brains doing when we're navigating through towns and cities? A new study from a team at University College London has made detailed maps of brain activity when negotiating the very windy London streets of Soho and compared it to what our brains are up to when we're simply following a sat nav. Hugo Spiers discusses the results and how this kind of neuroscience has a role to play in the future design of new street networks and cities.And we feature the private life of the octopus - a seemingly alien intelligence right here on Earth as philosopher Peter Godfrey-Smith discusses his new book "Other Minds: The Octopus and the Evolution of Intelligent Life", in which he literally dives into the oceans and delves in to the workings of the octopus mindProducer Adrian Washbourne.

The submarine famously named Boaty McBoatface is deployed this week for its first mission to examine a narrow submarine gap in the South Atlantic. Mike Meredith of the British Antarctic Survey tells Adam Rutherford how this research into the behaviour of deep water at this crucial point in the oceans will help us answer key questions about global ocean temperature flows.Some close-quarter flying in the wake of a jet has provided new insights on reducing aircraft pollution. Richard Moore at NASA Langley in Virginia describes how he's taken to the skies to measure gasses emitted by new biofuels to assess their impact in reducing carbon soot particles, aircraft contrails and climate-changing cloud formations across the skyAngela Saini visits the Bodleian Library in Oxford where the Bakhshali manuscript which contains possibly the very first graphical representation of the number zero is finally being carbon dated so we can better understand its scientific importanceAnd the habitable zones around stars in our the universe just got a whole lot bigger. Lisa Kaltenegger of the Carl Sagan Institute reveals how the presence of volcanoes pumping out hydrogen has a significant warming effect on planets, and increases the range of the so called Goldilocks Zone Producer: Adrian Washbourne.

From Skynet and the Terminator franchise, through Wargames and Ava in Ex Machina, artificial intelligences pervade our cinematic experiences. But AIs are already in the real world, answering our questions on our phones and making diagnoses about our health. Adam Rutherford asks if we are ready for AI, when fiction becomes reality, and we create thinking machines.

With Adam Rutherford and Francine Stock.

Adam Rutherford explores our relationship with contemporary humanoid robots

The idea of robots goes back to the Ancient Greeks. In myths Hephaestus, the god of fire, created robots to assist in his workshop. In the medieval period the wealthy showed off their automata. In France in the 15th century a Duke of Burgundy had his chateau filled with automata that played practical tricks on his guests, such as spraying water at them. By the 18th century craftsmen were making life like performing robots. In 1738 in Paris people queued to see the amazing flute playing automaton, designed and built by Jacques Vaucanson. With the industrial revolution the idea of automata became intertwined with that of human workers. The word robot first appears in a 1921 play, Rossum's Universal Robots, by Czech author Carel Chapek. Drawing on examples from fact and fiction, Adam Rutherford explores the role of robots in past societies and discovers they were nearly always made in our image, and inspired both fear and wonder in their audiences. He talks to Dr Elly Truitt of Bryn Mawr College in the US about ancient and medieval robots, to Simon Shaffer, Professor of History of Science at Cambridge University and to Dr Andrew Nahum of the Science Museum about !8th century automata, and to Dr Ben Russell of the Science Museum about robots and workers in the 20th century. And Matthew Sweet provides the cultural context. Show less

The World's oldest sedimentary rocks reveal traces of our earliest ancestors. New analysis shows life forms existed more than 3.7 billion years ago which were very similar to those found in our deepest oceans today, microbial life around hydro thermal vents. Some pollution might be good for the world oceans. New finding from China show how iron oxide pollution from power generation and industry has been turned into a source of nutrients for phytoplankton - by interacting with other chemical pollutants. The researchers say this is increasing the ability of the ocean to lock up atmospheric carbon dioxide and so reduce the impact of man made greenhouse gasses. They query whether reducing this kind of pollution could have a negative impact. This week The Royal Society celebrated LGBT history month and 50 years since the partial decriminalisation of homosexuality in England and Wales Rory Galloway meets Sir Dermot Turing, the nephew of renowned computer scientist Alan Turing, to discuss Alan’s Legacy for LGBT scientists today, and we look at the continued impacted of homophobia in science. And we hear about a new test for ideas in Evolution. This involves recreating the ancestors of fruit flies. The findings have overturned an established theory on genetic inheritance in these alcohol tolerant flies.

A woolly story about resurrecting mammoths raises serious questions for medical ethics. News of a scientist's plan to resurrect mammoths has spread around the world. However the story is largely untrue. We look at how this kind of 'fake science news' story can impact on perceptions of real medical research - some times with negative consequences. Almost all Europeans and Asians carry Neanderthal genes. Until recently these were thought to have little impact on us today, but new research shows they may be involved with determining height and aspects of both our physical and mental health. And what were Lennon and McCartney really thinking when they wrote their hit songs? Thanks to the number crunching power of computer algorithms the emotional content of 23 years worth of their compositions have been analysed. The results are both startling and for Beatles fans perhaps a little unsurprising.

Testing cyber security with science. The UK now has a new National Cyber Security Centre. However there is very little scientific evidence against which to test the detection of cyber attacks and effectiveness of measures to prevent them. We ask what is needed to turn cyber security into a more scientific discipline. Winston Churchill and Aliens. Throughout his life Churchill maintained a strong interest in scientific developments and wrote widely on subjects from quantum mechanics to nuclear energy. Newly discovered papers show he also had an interest in the potential for life on other planets. Dinosaurs and egg laying. A new fossil find revealing a dinosaur with an unborn baby suggests live births may have occurred many years earlier than previously thought. Turn off at level crossings. New research suggests personal messages about the impact of engine fumes on health may be the most effective way of persuading drivers to switch off their engines at level crossings.

Quantifying the impact of humanity on the earth's natural systems. Why human activity now has a larger effect on our planet than the forces of nature. We look at how mathematical equations can now be used to compare historical natural processes with contemporary man made changes. And we ask where current developments will take us in years to come.The Queen Elizabeth Prize for Engineering has been awarded to the inventors of digital imaging sensors. First invented in the 1970's, many of us use this technology everyday. These sensor can be found inside every digital camera ever made, from the devices used on space probes to collect distant images from the far reaches of the universe to the ubiquitous pocket cameras in our mobile phones.The earth is surrounded by junk - space junk. Many thousand of pieces of junk orbit the planet, left over from the history of everything we've ever sent into space. A new project has given a voice to this junk, and created a machine which plays simulated sounds of the junk as it passes overhead.Producer: Julian SiddlePresenter: Gareth Mitchell

Conservation and conflict. A year long BBC investigation has exposed an illegal animal trafficking network stretching from West Africa to the Middle East and Asia. Traffickers have used fake permits to undermine international conservation efforts. New developments in Quantum computing. Sussex University are building a new type of modular Quantum computer. We attempt to explain what Quantum computing is. A Massive citizen science project to map bird beak evolution- using records from the Natural History Museum. And the last scientific Glassblower at Imperial College gives us a demonstration of his craft.

The genes of unrelated others can influence our health and behaviour. New research suggests the genetic make up of our partners can have a profound influence on our lives. Scientists have quantified genetic influence , in mice at present but the plan is to try to extend this to human interactions. If accepted this has potentially far reaching consequences for studying heritability and also perhaps modern medicine as the findings suggest an illness can in part be influenced by those we live with. The use of DNA evidence in criminal cases has sometimes been given far more weight than it deserves. In the worst examples there have been miscarriages of justice where DNA evidence has been misinterpreted. The fiction of DNA as a 'magic bullet' pervades TV drama and films - but views of DNA evidence as infallible are also widely held amongst the public, police and lawyers. Forensic specialists explain what we can and can't find from DNA evidence. Oxford's Bodleian library has manuscripts stretching back to medieval times depicting volcanos discovered in the 6th century. These manuscripts also contain remarkable interpretations of eruptions and associated volcanic events, often mixed with mythology. Although those recording such events did not understand what they were scientifically, some of the depictions and ideas of what was happening are surprisingly accurate. Roland Pease and Professor David Pyle take a look at this remarkable collection. Nearly a hundred years ago, Oliver Lodge, eminent physicist and the first to demonstrate radio waves, published a book about life after death. It was entitled 'Raymond' after his son who was killed in the First World War. Lodge was a believer in ghosts and telepathy, and conducted experiments to test their existence. Adam Rutherford and Samira Ahmed look at how Oliver Lodge squared his scientific and spiritualist beliefs - and how the latter led to him, as Britain's most well know scientist of his time, being written out of scientific history.

Why the British Antarctic science base is being temporarily abandoned. New cracks have appeared in the Ice shelf on which the Halley research station sits. The promise of viro-therapy for treating cancer. Scientists have successfully used a virus to kill cancer cells. They say this could form the basis for a vaccine that could be injected to destroy tumours. The limitations of mouse models. Many animals are used for testing treatments intended for humans, we explain why the results of such experiments can't always be applied to people. Measuring wind speeds from space. A new satellite will lead to more accurate weather forecasts. Gene Cernan, the last man on the moon. We celebrate the charismatic astronaut who has died aged 82.

Why the simplest explanations are not always the best when it comes to science. Where you read about a scientific subject can affect not just what you learn but also how much you think you know about the subject.Quahogs are a kind of clam and they can live for hundreds of years. Analysis of their shells provides a record of historical climate change. Researchers studying their shells have found big differences between the drivers of climate change now and in the pre-industrial era. Trips to the dentist may become less frequent if an experimental treatment with stem cells becomes widespread. The treatment involves regrowing damaged dentine, bringing about a natural tooth repair. Radio telescopes have brought us signals from the far reaches of the known universe and listened in on the space race. Now a new generation will take us further than ever before. Producer Julian Siddle.

The world's oldest known killer whale is presumed dead. At an estimated age of 100 years, 'Granny' was last seen with her family in October. The scientists who've followed her and her pod for four decades announced that they believe she has died somewhere in the North American Pacific. Adam Rutherford talks to evolutionary biologist Darren Croft of the University of Exeter about this remarkable animal and the insights that Granny and her clan have provided on killer whale social life and the evolution of the menopause.Adam also hears how a 'kitchen' experiment with Silly Putty and the form of carbon known as graphene led to the creation of an ultra-sensitive electro-mechanical sensing material. G-putty may provide the basis for a continuous and wearable blood pressure monitor. It can also detect the footsteps of spiders. Professor Jonathan Coleman of Trinity College, Dublin explains how its properties arise from mixing the two materials.Reporter Marnie Chesterton tells how a 700 tonne magnet was moved 3,000 miles by road and river across the United States, inciting both conspiracy theories and adulation. Now homed at Fermilab - the US's premier particle physics lab - the magnet is about to start probing the laws of the Universe in the Muon g-2 experiment.BBC science correspondents Rebecca Morelle and Jonathan Amos pick their space and astronomy highlights for the coming year.Producer: Andrew Luck-Baker.

Adam Rutherford puts listeners' science questions to his team of experts: physicist Helen Czerski, cosmologist Andrew Pontzen and biologist Yan Wong. Queries include gravity on sci-fi space ships, how animals would evolve on the low gravitational field of the Moon, gravitational waves, mimicry in parrots, sea level rise, the accelerating universe, dinosaur intelligence, the Higgs field and concerns about oxygen levels in the atmosphere. Further questions are answered in the podcast version of the show. They cover Antarctic dinosaurs, reducing CO2 levels in the atmosphere by trapping it as limestone, and Neanderthal DNA.

Can Inuit people survive the Arctic cold thanks to deep past liaisons with another species? Adam Rutherford talks to geneticist Rasmus Nielsen who says that's part of the answer. His team's research has identified a particular section of the Inuit people's genome which looks as though it originally came from a long extinct population of humans who lived in Siberia 50,000 years ago. The genes concerned are involved in physiological processes advantageous to adapting to the cold. The conclusion is that at some point, the ancestors of Inuits interbred with members of this other species of human (known as the Denisovans) before people arrived in Greenland. Also in the programme: The woodlice which are made either female or male because of a gene that once belonged a bacterium. The gene came from a dead microbe and was incorporated by chance into the woodlouse genome. This is the first known instance of the invention of an animal sex chromosome through bacterial donation. We talk to Richard Cordaux of the University of Poitiers and Nick Lane of University College London about the discovery. Peace through particle physics. Roland Pease visits SESAME in Jordan - the Middle East's first synchrotron facility is about to start operating. The experiment brings together scientists from all over the Middle East in common cause, with for example Israeli, Palestinian, Iranian, Egyptian and Turkish scientists working side by side. Marine ecologist Autun Purser tells Adam about his European team's discovery of ghostly octopods living at 4,000 metres on the dark, cold sea bed of the Pacific ocean. Autun's camera has caught extraordinary egg brooding behaviour by this new kind of octopus. It lays its eggs half way up the stalks of dead sponges and then guards them for several years until they hatch. Unfortunately, the sponges only grow on lumps of metal-rich rock called manganese nodules which form slowly on the deep sea floor. Several companies are now exploring the possibility of extracting vast quantities of these nodules in deep sea mining, threatening the existence of the sponges and the octopods depending on them.

Could rocks studied by the Mars rover Spirit in Gusev Crater in 2007 contain the hallmarks of ancient life? Geologist Steve Ruff of Arizona State University talks about what he found in hot springs in Chile which begs that question. He says the evidence is intriguing enough for NASA to send its next and more sophisticated Mars robot back to the same spot on the Red Planet in 2020.Adam also talks to Phil Bland of Curtin University in Australia - one of the creators of the Desert Fireball Network - an array of automated cameras across Australia, built to locate where shooting stars land as meteorites and also pinpoint from where they came in the solar system. Boosting the chances of collecting these meteorites and knowing their space origins should helps us to better understand how the Earth and other planets formed 4.5 billion years ago.There's new compelling evidence that microbes in the gut play a role in the development of Parkinson's disease. Tim Sampson of Caltech in the US outlines his experiments which raise this possibility and Patrick Lewis, another Parkinson's researcher at the University of Reading, puts the new findings into a wider context.Adam takes a tour of the spectacular new mathematics gallery at the Science Museum in London. The Winton Gallery's exhibited objects and design by the celebrated architect Zaha Hadid focusses on mathematics in the real world. Adam's guide is lead curator David Rooney.

Alzheimers disease is now the leading cause of death in the UK, but there are as yet no treatments to halt or reverse it. There was huge disappointment last week when the drug company Eli Lilly announced that a large, phase 3 clinical trial had failed to show any benefit to mild dementia sufferers from its antibody therapy, solanezumab. So where does this leave our basic understanding of biology of Alzheimers disease and how we might most effectively treat or cure it? Adam Rutherford talks to Alzheimers researcher Tara Spires-Jones of the University of Edinburgh.Also in the programme: The skeleton of the world's most famous fossil, Lucy, has received a body scan which revealed she spent a considerable portion of her life climbing trees. Researchers at the University of Bath are making smart bandages for burns patients which glow when their wounds become infected. Adam also talks to the astrophysicist who gave up studying exploding stars to apply his maths to Hollywood stars in the movie business.

Bdellovibrio is a small bacterium which preys and kills other bacteria. A team of researchers in the UK has shown in animal experiments that injections of the predator microbe can successfully treat infections. So how close does this take us to Bdellovibrio therapy for human patients and what part might it play in tackling the growing crisis of antibiotic resistance? Adam Rutherford talks to Professor Liz Sockett of the University of Nottingham. The British government has announced that it will be spending an additional £2 billion on research and development by 2020. Commentators say it is the largest hike in public funding for science in a very long time. Dr Sarah Main of the Campaign for Science and Engineering, and Dr Arnab Basu, physicist and CEO of Kromek, discuss the new money and how it would be best used.Also in the programme, materials and electronics engineers in the US have devised a small wearable heart monitor - the size and thickness of a sticking plaster. Adam talks to its lead designer Professor John Rogers of Northwestern University in Chicago. And could phobias be cured without exposure to the thing which frightens people? Dr Ben Seymour outlines an intriguing experiment which involved reading people's thoughts in a brain scanner, which suggests ultimately it may be possible.

Does the distant dwarf planet Pluto have an ocean beneath its thick crust of ice? It's certainly possible, according to a group of researchers who are analysing the data from the New Horizons Pluto flyby last year. They argue that a deep ocean of water would best explain the position of the great heart shaped depression on Pluto's surface. Adam Rutherford quizzes planetary scientist Francis Nimmo about this new hypothesis.Adam also talks to glaciologist Robert Mulvaney of the British Antarctic Survey, who is now setting off for the frozen south to prospect for the oldest ice in Antarctica. He's part of a European project which aims to drill deep into the ice sheet of East Antarctica and chart the climate and atmosphere history of Antarctica back to 1.5 million years ago. Are grass-fed cattle better for the global climate than cattle fed on grain-based feeds? Dr Tara Garnett of the Food Climate Research Network at Oxford University responds to listeners comments on carbon emissions and diet.Swifts can fly for 10 months non-stop, never touching the ground. Anders Hedenstrom of Lund University discovered this remarkable fact by fitting birds with a tiny electronic backpack which recorded their location and flight activity across a whole year.

Climate change is in the news this week. The international Paris agreement to curb global temperature rise has just come into effect but President Elect Donald Trump has said he would take the United States out of the process. In BBC Inside Science, Adam Rutherford puts listener's questions and views about climate change to experts, such as the emissions reduction impact of becoming a vegan to a proposed technology to remove carbon dioxide from the planet's atmosphere. Myles Allen and Peter Scarborough of the University of Oxford, and Anna Harper of the University of Exeter are consulted.The programme also visits a lab at the Open University which studies the way animals interact with computer technology. Research includes technology to enable dogs to phone the emergency services if humans get into trouble, and using dogs to detect cancer. Reporter Marnie Chesterton meets researcher Clara Mancini and dogs Ozzie and Tory.Are there commonalities across the world's languages between the sounds in particular words and the meanings of those words? The traditional thinking in linguistics says no. But new research surveying the meaning and sounds of words across 6,000 languages from the Americas, Asia, Europe and Australasia finds otherwise. The 'r' sound is used in words for the colour 'red' all around the world at frequencies much higher than by chance. The case is the same for the words for 'nose' and other parts of the body. Morten Christiansen of Cornell University talks to Adam Rutherford about the research.

In the past three months, central Italy has been shaken by several large earthquakes. The quake near Norcia on 30th October was the most powerful for decades. In late August, another struck near Amatrice, causing 300 lost lives. Adam Rutherford talks to seismologist Ross Stein about why this part of the Italian peninsula is so prone to shaking, whether there is a pattern in the recent activity and whether the scientists are getting any better at earthquake forecasting. The recent Ebola epidemic in West Africa was the largest and most deadly of its kind so far. More than 11,000 people were killed by the virus. Now two groups of virologists have discovered that early in the epidemic's course, the Ebola virus underwent a genetic change which allowed it to infect human cells more easily. Could this mutation explain the terrible scale of the outbreak of 2013 to 2016? Also in the show, the chemists who are aiming to make ammonia fertiliser production more environmentally friendly but made rocket fuel instead; and the past and future of the Chinese space programme.

Adam Rutherford meets the Australian scientist behind a radical new technique to prevent mosquitoes from spreading the zika and dengue fever viruses to people. The method involves infecting mosquitoes with a harmless bacterium. The microbe doesn't kill the mosquitoes but stops the viruses multiplying inside them and spreads rapidly through wild mosquito populations. After 15 years of research, the mosquito control method is about to be deployed in large scale trials in urban areas in South America.Also in the programme, the world's atmosphere crosses an iconic threshold as measured by the concentration of the greenhouse gas carbon dioxide: scientists get their hands on the rocks at the centre of the extinction of the dinosaurs: and details emerge of why the European Space Agency's recent Mars lander crashed onto the Red Planet.

Biologists are to begin a 10 year international project to map the multitude of different kinds of cell in the human body. The average adult is built of 37 trillion cells and if you look in a text book, it will say there are about 200 distinct varieties of cells. But this is a grand underestimate. There could in fact be 10,000. The Human Cell Atlas project aims to identify every type and subtype of cell in every tissue of the body - a massive endeavour which, the cell mappers argue, will have profound benefits for medicine. Adam Rutherford also talks to zoological archaeologist Angela Perri whose research is aimed at discovering when our ancestors first started to use dogs as 'hunting' technology. Her work involves joining hunts with dogs in the modern day as well as traditional archaeological field work. He also explores the science behind exploding smart phone batteries and the new international climate agreement to rid the world of hydrofluorocarbons.

Mars is about to be visited by the first space mission for 40 years which is designed to seek signs of life on the Red Planet. Adam Rutherford talks to Dr Manish Patel of the Open University, a senior scientist on the European Space Agency's ExoMars Trace Gas Orbiter. Once the spacecraft starts work, it may solve the mystery of ebbs and flows of methane gas in the Martian atmosphere. It may answer whether the gas is being produced by life beneath the planet's cold dusty surface. The American space agency Nasa already has a mission well underway on the Martian surface.. For four years, Curiosity has been exploring the deep geological past of a huge Martian crater and mountain. Recently possible signs of liquid water have been seen nearby. But rather than going closer to study it, Nasa wants the rover to avoid it. Project scientist Ashwin Vasavada explains why. Carlo Rovelli is a theoretical physicist and writer. His latest book 'Reality is not what it Seems' explores the history of thought about the physical nature of the universe and one of the latest incarnations of that great quests - loop quantum gravity theory. He talks to Adam about the fine grain of space and time, and exploding black holes. Palaeontologist Julia Clarke has discovered the oldest fossil of a bird's organ of song, the syrinx. At the University of Texas, Austin the delicate structure turned up in an X ray scan of a 66 million year old bird fossil from Antarctica. The fossil syrinx is so well preserved, it is possible to say what the call of this ancient bird Vegavis would have sounded like. It's also a massive boost in the quest to discover when birds first sang and recreating the dawn chorus back in the Age of Dinosaurs.

The government has announced that tiny pieces of plastic in personal beauty products that end up in the oceans will be banned from sale in the UK. But given their size how much of a problem are minuscule bits of plastic to marine life? Gareth Mitchell meets Professor Richard Thompson of Plymouth University to uncover the marine biology concerns that have led to the micro bead ban. However much we watch animals in the wild we can't really know what they get up to. Rory Wilson, Professor of Zoology at Swansea University, has found a way to eavesdrop on animals that live in remote parts of the world and he's revealed some of his latest discoveries at the British Science Festival in Swansea today. He's developed a logging device that collects a whopping amount of data - 400 items each second. His daily diary collects amongst other measurements, location, magnetic field, temperature, and pressure. Before his talk, Adam Rutherford went along to Rory Wilson's lab and found out which animals he's attached the logger to and discovered their secret life. In the final entry of this year's shortlist for the Royal Society book prize Jo Marchant discusses Cure - which examines how the mind plays a crucial role in health. Our thoughts, emotions and beliefs, it seems, can ease pain, heal wounds, fend off infection and heart disease and even slow the progression of AIDS and some cancers. So what is the potential of the mind to heal - and what are its limits? As many as 530 key infrastructure sites across England are still vulnerable to flooding, according to a government review out today. Southampton University researchers want to understand better how floods happen and how to predict them. Beyond burst river banks and breached defences, they're building up a more detailed picture, house by house, and street by street of what happens when water levels rise. For that they need data, lots of it going back as far as possible. Ivan Haigh at the National Oceanography Centre and his colleagues are pulling all kinds of photos and records together in an interactive multi-purpose online shared database called Surgewatch. Presenter Gareth Mitchell Producer Adrian Washbourne.

The nearest habitable world beyond our Solar System might be right on our doorstep . Scientists say their investigations of our closest star, Proxima Centauri, show it to have an Earth-sized planet orbiting about it. What's more, it is moving in a zone that would make liquid water on its surface a possibility. Gareth Mitchell hears from Guillem Anglada-Escudé whose "Pale Red Dot" team made the discovery and discusses what the "earth- like" claims actually mean. The planet hunters of today search for worlds beyond our Solar System. The planet hunters of a century or so ago, were still going crazy trying to find one more planet orbiting this sun. In The Hunt for Vulcan shortlisted for this year's Royal Society Book Prize, Prof.Thomas Levenson examines the craze known as Vulcan -mania, in the desperate search for another planet in an attempt to explain the odd orbit of the planet Mercury. But why did the phantom planet theory survive for so long? We examine observations from space of fleeting blue lakes in East Antarctica. They come and go with the seasons, forming during the warmer months of the south pole summer. As Amber Leeson of Lancaster University explains, many of the lakes then drain away, an effect already been found in Greenland but never, until now, in this part of the Antarctic. And their effect is cause for concern. Deep sea sharks are nearly impossible to track around the planet, however they inherit the chemistry of the things they eat. Researchers at Southampton University have worked backwards and by examining the chemistry of the sharks, they've been able to determine what things a shark has been eating but also where in the world it has been feeding. Chris Bird and Clive Trueman discuss how they're building up the first accurate pattern of their extraordinary movements. Presenter: Gareth Mitchell Producer: Adrian Washbourne.

Ford has just announced that by 2021 it's going to have a driverless car on the road with no steering wheel. It sounds ambitious, since it is the intermediate stop on the road to full autonomy that's raising some of the big research questions at the moment. How can drivers enjoy the reduced workload of automation whilst still being alert enough to take control if something goes wrong? For a drive of the future, Gareth Mitchell went to Southampton University's simulator facility for automated vehicles to meet Professor of Human Factors in Transport, Neville Stanton.Neonicotinoid pesticides have been used widely in protecting the UK's vast acreage of oil seed rape. Research out this week claims there is a link between 'neonics' as they're known, and waning numbers of bees - with the worst affected populations declining by a third. The study has grabbed the headlines because of its scope - 18 years' worth of observations in the countryside. But how much is the link a cause for concern? Researchers Ben Woodcock and Nick Isaac of the Centre for Ecology and Hydrology discuss the results.Nestled in the Vale of Pewsey, Marden Henge is an artificial mound considered by archaeologists to be one of the best of the area's neolithic monuments. It represents the missing link between the stone circles at Stone Henge and Avebury. Teams from Reading, Historic England, and other volunteers, have been digging there this summer. Roland Pease has been along to meet them.And we've the next nomination in this year's Royal Society Science Book prize shortlist: Tim Birkhead's new book, The Most Perfect Thing, all about bird eggs. It covers how they are made, why they are the shape they are, where their patterns come from and much more.Producer Adrian Washbourne.

New results have squashed the hope that the hints of a new particle detected by the Large Hadron Collider would confirm the existence of something extremely exotic, such as a new Higgs, or even the theoretical Graviton. Instead, the intriguing data 'bump' turns out to be nothing more than a statistical fluctuation. Physicist Jonathan Butterworth of UCL discusses whether this false alarm affects the LHC's chances of finding something else.Crows, ravens and other members of the bird family we call Corvids are well known to have sophisticated skills in tool use and problem solving. Research out this week reports ravens bending wire to help forage for their food. But what constitutes intelligence in bird brains? Adam Rutherford visits the Tower of London where ravens have been permanent residents since the 16th Century, and so quite a good spot for scientists to go and put bird brains to the test. He meets Sophie Hamnett and Nathan Emery from Queen Mary, University of London.Animals evolved in the seas, but by about 400 million years ago, some fishy creatures had evolved to begin walking on terra firma. Nowadays we look at creatures like mudskippers, that can swim and wade, to see how those first crawlers might have crept up the beach. A new study has gone one step further: Jonathan Webb went to Georgia Tech in Atlanta to meet the robot mudskippers.We're profiling each of the shortlisted books for the Royal Society book prize this year, and this week it is the turn of oncologist Siddartha Muhkerjee. He has turned his attention to trying to understand the root of all cancers, and the mental health issues his own family endure. His new book, The Gene, details the central concept in inheritance.Producer Adrian Washbourne.

What should we be looking for when searching for life on other planets beyond our solar system? Scientists urgently need to come to a consensus on this as a new suite of telescopes soon begins detecting. The space agency NASA has put together a virtual institute called The Nexus for Exoplanet System Science, and they've just met to work out how we should be looking for bio signatures - on the burgeoning catalogue of worlds beyond the Solar System. Adam Rutherford hears from Sarah Rugheimer, an astrobiologist from the University of St Andrews, on why the world's astrobiologists have decided to lay down the law.The Royal Society Insight Investment Book Prize celebrates some of the best science published each year. Today the judges announced their shortlist: The Cure by Jo Marchant; The Gene by Siddhartha Mukherjee; The Hunt for Vulcan by Thomas Levenson; The Invention of Nature by Andrea Wulf; The Most Perfect Thing by Tim Birkhead; The Planet Remade by Oliver Morton. We're talking to all the authors over the next 6 weeks before the winner is announced on the 19th of September. The first is Oliver Morton's The Planet Remade: How Geoengineering Could Change the World.Bee hives have evolved to have a complex, fascinating social hierarchy, and although we know about Royal Jelly and pheromones, how exactly does the queen bee control the fertility of the rest of the hive? A team of New Zealand geneticists, Peter Dearden and Elizabeth Duncan, has finally worked it out.This Saturday's evening BBC Prom is set in space. The National Youth Orchestra performs The Planets by Holst, and Richard Strauss' Also Sprach Zarathustra. But the concert begins with a piece inspired by this year's detection of Gravitational Waves by LIGO, the Laser Interferometer Gravitational-Wave Observatory. Gravitational Waves composer Iris Ter Schiphorst discusses how she went galactic.Producer: Adrian Washbourne.

The dinosaurs met their end with a massive bang when, 66 million years ago, a 6 mile-wide rock crashed into the Gulf of Mexico. This was bad news for the dinosaurs, and consequently good news for the mammals left behind. Thomas Halliday is a palaeontologist, who specialises on the rise of the mammals, and his new work unpicks what happened to survivors after 75% of the species on earth died. The Neanderthals were found in Gibraltar back in 1848. Ever since then, teams have been exploring the caves systems on that rocky outcrop of Europe. It's known as Neanderthal City and researchers think it was home to the very last of these people, some 30,000 years ago. BBC science reporter Melissa Hogenboom has just returned from Gibraltar and talks to Adam about the recent findings of abstract art, which suggest that Neanderthals are much more like us than previously thought. We generally find the combination of notes in a consonant chord more pleasant to our ears than a dissonant one. The question is whether that reaction is learnt or simply part of our biology. It's a tricky thing to test because music is culturally ubiquitous. Neuroscientist Josh McDermott has found a way around this, by playing those tunes to members of a very remote Bolivian tribe - the Tsimane - and gauging their reactions. One year on since the New Horizons probe zoomed past Pluto, Kathy Olkin, one of the chief scientists behind the mission talks to Adam about how the team have dealt with the new data. Noah Hammond from Brown University explains how he has used photographic data from New Horizons to examine the cracks in the surface of Pluto, and has suggested how they came to be. Presenter: Adam Rutherford Producer: Adrian Washbourne.

Earlier this week, the US space agency successfully put a new probe in orbit around Jupiter. The Juno satellite, which left Earth five years ago, had to fire a rocket engine in a tricky and precise manoeuvre in order to brake and become ensnared by Jupiter's gravity. Fran Baganal is a mission scientist for Juno and tells Adam Rutherford what measurements Juno is now in position to make. Space is full of junk left over from past space missions: from flecks of paint to used rockets, dead satellites, also debris from past collisions of space junk. This junk is speeding around the Earth at several thousand miles per hour. At those speeds even small pieces of rubbish just fractions of a millimetre across can damage communication satellites which are vital for the web, mobile phones, and satellite navigation on earth. The Surrey Space centre team are preparing to launch the world's first space litter-picking mission. The RemoveDebris team share their clean up designs with Adam. Researchers have had success growing body parts like windpipes and ears in the laboratory for use in transplants. A group of scientists at Barts Cancer Institute in London are making own tumours; tissues we don't want. However, it is important to study how they grow, and co-opt other cells in the body. Reporter Anand Jagatia heads to their tissue lab to see what they've grown. All animals take risky decisions all the time. The ability to assess the potential gain from the potential harm, and make the right choice, gives the animal an evolutionary advantage. A new study suggests that plants are capable of making similar calculations, despite not having brains. Alex Kacelnik at Oxford University is one of the scientists behind the experiment that suggests that pea plants are willing to gamble. Presenter: Adam Rutherford Producer: Adrian Washbourne.

NASA's Juno Probe arrives at Jupiter on 4th July, where it will execute a daring loop-the-loop in order to get closer to the giant planet than any other spacecraft in history. Juno is constructed like an armoured tank, because Jupiter is surrounded by a belt of very intense radiation that can quickly fry most spacecraft electronics. On July 4, Juno's engines will attempt to slow the probe down so it can be sucked into Jupiter's orbit. The slightest error could mean Juno misses this window, putting an end to the $1.1 billion mission. The man in charge is Dr Scott Bolton, and he speaks to Adam from Pasadena in California. Traditional art conservation tends to focus on paintings - how to stop paint from peeling. But contemporary art uses a much broader range of materials; plastics, rubber; pickled sharks. This means that an ever-increasing array of techniques are needed to conserve those materials. A new project is looking at the role nanotechnology can play, as Rob Thompson reports. It's National Robot Week. There is a fear that robots will replace many of the jobs done by humans. But what if robots just stuck to emptying the gutters and fixing potholes; the chores that humans find tedious? Professor Phil Purnell from Leeds University has just launched a project that aims to use robots to fix bits of the city - finding and patching tiny defects before they turn into massive sinkholes. The European eel may be mysterious, and delicious but it is also critically endangered. The only reason we know this is because of organisations like the Zoological Society of London. They do the unglamorous job of monitoring these fish caught in traps in rivers around the UK. Marnie Chesterton went along to count eels in rainy Brentford with ZSL's Joe Pecorelli, who shares his knowledge of this creature's epic life journey.

This week is National Insect Week. Almost all animals on Earth are insects, and entomologist Adam Hart told us why we're celebrating and studying them in such detail - particularly diamondback moths, which have recently arrived the UK in large numbers. On the first official (and rather rainy) day of summer, we went down to Butterfly Paradise at London Zoo for the event launch. Entomologist Adam Hart tells us what the Week is all about.New research out this week suggests that a so called "electric wind" has stripped all the water away from the surface of Venus. Space scientist Glyn Collinson at NASA Goddard Space Flight Centre has led this electrical field study.Wales has 1300 rivers with illegal levels of heavy metals. Toxic metals like lead, zinc and copper are a legacy left over from when the area was heavily mined. Natural Resources Wales and Innovate UK set a competition to look for technology that would clean up these rivers. One of the winners was Steve Skill from Swansea University, who has come up with some biotechnology that uses algae to suck the poison out of the rivers.The Championships at Wimbledon start next week, and whatever the weather, the grass has to be perfect. Adam Rutherford headed to London's SW19 to find out how the ground staff are using scientific evidence to cultivate the courts.Producers: Marnie Chesterton & Jen Whyntie.

Gravitational waves have been detected for a second time. These waves are ripples in the curvature of space time, predicted by Einstein in his General Theory of Relativity in 1916. Back in February, the Laser Interferometer Gravitational-Wave Observatory (better known as LIGO) announced that they had detected the signal of gravitational waves from the collisions of two big black holes. The detection in February was the first observation of these waves, and confirmed General Relativity. This week, LIGO confirm a second detection. BBC Science Correspondent Jonathan Amos explains what is new about these new gravitational waves. We know more about the surface of the moon than we know about the ocean floor. Admittedly, the sea is much more dynamic, the scene of many chemical and biological processes, about which scientists would like to learn more. This week, cartographers meet in Monte Carlo, to discuss their plan to map the ocean floor by 2030. Roland Pease reports on the ocean-mapping options. 40 years ago, The Selfish Gene, by Richard Dawkins was published. Since then, it has been a perpetual bestseller. In it, Dawkins explains that the gene is the unit of natural selection, an idea that has become central to all biology. Adam Rutherford speaks to Richard Dawkins, and his co-author on ‘The Ancestor’s Tale’ Yan Wong, at the Cheltenham Science Festival, to discuss the impact of The Selfish Gene. The spoonbilled sandpiper is standing on the edge of extinction, but in good news, Adam hears about of a clutch of eggs laid not in their native Russia but in Slimbridge in Gloucestershire. BBC producer Andrew Luck-Baker visited the Wildfowl and Wetlands Trust’s population back in April, and describes these birds to Adam.

This week we're dedicating the whole programme to one of the biggest threats to humanity. We're already at 700,000 preventable deaths per year as a result of antibiotic resistance, and the O'Neill Report suggests that this will rise to 10 million people per year by 2050. Today, we're focussing on the attempts to discover new antibiotics, and alternative therapies for combating bacterial infection. Firstly, we wanted to know why new antibiotics aren't being produced. Dr Jack Scannell, an expert on the drug development economics, told Adam Rutherford why money has been the main barrier.Most of the antibiotics we use were discovered in the mid-20th century, but as the threat of drug resistant infections increases, the race is on to find new organisms that make novel medicines. We have only identified a tiny fraction of the microbes living on Earth and are "bioprospecting" for useful ones in wildly different locations. Microbiologist Matt Hutchings has been looking to the oldest farmers in the world - leaf cutter ants.From exotic locations to under your fridge: Dr Adam Roberts runs a scheme called Swab and Send. It's a citizen science project that asks members of the public to swab a surface and send the sample to him – he'll analyse them to look for the presence of new antibiotic-producing bacteria. We joined in the hunt by swabbing spots around the BBC: Adam's microphone, the Today programme presenters' mics, our tea kitchen's sponge, the revolving entryway doormat, and lastly, the Dalek standing on guard outside the BBC Radio Theatre.Antibiotics are not the only weapon in the war against bacteria. A hundred years ago, a class of virus that infect and destroy bacteria were discovered. They're called bacteriophages. Phage therapies were used throughout the era of Soviet Russia, and still are in some countries, including Georgia. Phage researcher Prof Martha Clokie told us whether phage therapy might be coming to the UK.

We face many global problems, such as drought, flooding and climate change. All of these issues are rooted in science. It'll take politics and people and business to fix them, or for us to manage them, but none of that can happen without a solid scientific base.In front of an audience at the Hay Festival, Adam Rutherford is joined by Steve Jones, Professor of Genetics at University College London, Marcus du Sautoy, the Simonyi Professor of the Public Understanding of Science at the University of Oxford, and science journalist, Gaia Vince, to discuss what the future holds for humanity and the planet, what we can know, what we can predict, and what is to come.Adam Rutherford talks to Gaia Vince about the new age of man, the Anthropocene, and the impact it is having on peoples' lives, to Marcus du Sautoy about chaotic systems and when maths can and cannot predict the future, and to Steve Jones about forecasting human population growth and how we are still evolving.

The topic of GM plants raises strong opinions and many questions. This week, the Royal Society published answers to some of those questions. Adam speaks to Professor Ottoline Leyser, plant science expert and Head of the Sainsbury Lab in Cambridge. She was involved in writing the responses and Adam quizzes her on the possible issues with GM crops.Institutes from around the world made deposits to the Svalbard Global Seed Vault this week. More than 8,000 varieties of crops from Germany, Thailand, New Zealand, and the World Vegetable Center arrived at the Vault, located on a remote Norwegian archipelago, to be stored deep within the permafrost. Reporter Marnie Chesterton was there to see it happen, and take a tour of this normally inaccessible place. The Vault is located within the Arctic Circle, and helps to protect the biodiversity of some of the world’s most important crops against climate change, war and natural disaster. This week Professor Frances Arnold was awarded the Millennium Technology Prize; the Finnish version of the Nobel Prize. Her work is a process called Directed Evolution, and involves creating batches of mutant proteins to see if the mutations make them better at certain functions. Dolphins use ultrasound to echolocate. Until recently, scientists did not quite know how. Making ultrasonic noises normally requires some hard surfaces such as metal, and dolphins don’t have metal in their blowholes. Acoustic scientists Aaron Thode at the Scripps Institute of Oceanography in San Diego thinks he’s solved this conundrum, and it involves snot. Producer: Jen Whyntie

Today we're asking how anyone can make sense of the deluge of climate change data that is almost continually published. By the end of last month, nearly 200 countries had signed up to the Paris climate change agreement, and in doing so they were nominally committing to keep global temperatures "well below" 2C. So now comes the tricky bit: How best to do that - and what is the scientific evidence for policymakers to decide? Climate change expert Dr Tamsin Edwards of the Open University joins Adam Rutherford to help us unpick the research. Last week a major new report on the State of the World's Plants was unveiled at Kew Gardens in London. There are some 391,000 vascular plants known to science - that's ones with vessels, xylem and phloem - and over 2000 were discovered last year alone. But just over a fifth of all plants are estimated to be threatened with extinction - and global climate change forms part of this threat. Our reporter Cathy Edwards met Professor Kathy Willis, Director of Science at Kew, to find out how plants are responding to the changing climate, and also spoke to Professor Yadvinder Malhi, Oxford University, and Kay Havens, Chicago Botanic Garden.The Review on Antimicrobial Resistance, headed by economist Jim O'Neill, was published today. Molecular microbiologist Professor Matt Hutchings from the University of East Anglia, gave us a brief summary.A new paper out this week looks into exactly what the act of making a phone call can reveal. The study, which was led by Patrick Mutchler and Jonathan Mayer at Stanford University in the States, is the culmination of work looking into what metadata really can show - you may have seen reports of some of their findings, as they've been revealing them in the public interest since 2013. They collected metadata volunteered by 823 participants, in total, more than 250,000 calls, and 1 million text messages. Steven Murdoch from the Information Security Research Group at University College London joined us to put this into context. As part of the BBC's Do Something Great season celebrating volunteers, Adam joined Professor Kate Jones from University College London on a Hampstead Heath bat watch, part of the citizen science project Bat Detective. Producers: Marnie Chesterton & Jen Whyntie.

The biggest study of the relationship between genes and educational attainment - in this case, basically the measure of how long you stay in education - has been published this week. A huge number of environmental factors influence this trait, but genes also play a small role. In the new study, a large team of researchers looked at over 300,000 people and identified 74 genetic variants, slight differences in our DNA, that do seem to associate with how long those individuals stayed in formal education. Senior author Dan Benjamin, University of Southern California, and social genetics researcher Eva Krapohl from Kings College London helped steer us through this complex quagmire.The Derbyshire village of Eyam is famous amongst Plague historians because when the disease arrived in a bale of cloth in 1665, the local vicar took a bold step and quarantined the whole village. 260 villagers died, but the sacrifice is thought to have saved surrounding populations. This noted event yielded a rich data set, which Eyam residents Francine Clifford and her late husband John meticulously mined over the last few decades. When epidemiologist Xavier Didelot of Imperial College London visited the local museum whilst on holiday, he couldn't resist investigating.Later this month, in pubs around Britain, and bars in 11 other countries, audiences will gather to hear about everything from black holes to cancer treatments - all part of a phenomenon called 'Pint of Science'. Marnie Chesterton went to The Castle in Farringdon to hear more.Finally, last week we met Poppy, one of the Labradors likely to have a newly discovered genetic reason for eating her owners out of house and home. Poppy's most notable devouring was of a large birthday cake, resulting in a trip to the vet's to get her stomach pumped. A fellow cake-eating-Lab-owning listener got in touch to ask why this procedure was necessary. It all comes down to the flavour of the cake: Chocolate.Producers: Marnie Chesterton & Jen Whyntie.

In a major advance in the field of embryology, scientists this week have kept human embryos alive in petri dishes for record amounts of time. The legal limit for keeping fertilised human embryos in the lab is 14 days, a cut-off point set in 1979. Back then, scientists were able to keep embryos alive for only a few days, meaning the limit was only a theoretical one. Advances mean that this week, in 2 papers, researchers have reached that limit. Professor Ali Brivanlou, Robert and Harriet Heilbrunn Professor of Stem Cell biology and molecular embryology at Rockefeller University is lead author on one of the papers, and Professor Bobbie Farsides is a clinical and biomedical ethicist at Brighton and Sussex Medical School. They join Adam to discuss the next steps for embryology. Should this limit curtail research? Next Monday is the transit of Mercury. 13 times a century, Mercury passes directly between us and the Sun, and creates a pinprick shadow, a pixel of black for about 8 hours. This strange planet has no atmosphere, but a lot explosive volcanic activity. It has an eccentric orbit - meaning its distance from the sun fluctuates wildly. A Mercury year is 88 Earth days, but a Mercury day lasts almost two mercury years. David Rothery is a professor of Planetary Sciences at the Open University. He reveals how scientists study this planet and explains how, and how not to view the transit of Mercury. Overfishing is one of the biggest threats to the health of our oceans. According to the UN, up to a third of the world's fisheries are overexploited or depleted. It is a huge complex problem with many inputs and outputs to compute. So who better to tackle it than a team of hackers? Recently, coders around the globe gathered to take on the challenge, in a 48-hour Fishackathon. Reporter Anand Jagatia went along and reports back to Adam Most dog lovers will know that Labradors are particularly keen to eat anything, all the time, at any time. As a result, some are a bit corpulent, even obese. The cause is likely to be in their genes. A new study in the current issue of Cell Metabolism has identified that genetic basis for the perpetual hunger. Eleanor Raffan from Cambridge University, geneticist and vet, led the study. She explains to Adam how she gathered a cohort of dogs.

30 years ago this week an explosion at the Chernobyl nuclear plant. A fire raged for 10 days, spewing radioactive materials on the surrounding area and was detected throughout much of a continent. Yet, so many decades on, why is it so difficult to accurately measure the impacts on human health? Richard Wakeford of the University of Manchester is an epidemiologist who has looked at the research done over the years, and he explains why making definitive connections between the Chernobyl explosion and long-term illnesses or premature deaths is so very difficult. In the last few days there have been reports that a drone hit a plane on its way into Heathrow. Investigators say there is so little evidence either way it is not possible to say whether it really was a drone, but either way, the story has raised concerns. BBC Inside science spoke to Dr Sue Wolfe of ARPAS, to find out how our increasingly crowded air space is regulated. And Adam goes drone flying with BBC innovations producer, Derrik Evans, to see how easy these things are to use. If the hum of drones is annoying, imagine the constant din of the rain forest, especially tricky if you're a cricket and you're trying to find a mate. We have a listen to the strategies they use to be heard above the cacophony in the company of Dr Tim Cockerill. Scientists at CERN have also been trying to sort out the wheat from the chaff, continuing their efforts to understand a blip in their data identified and scrutinised over the last few months. Jon Butterworth of UCL and CERN dons the Cloak of Speculation and talks about the possible implications for physics if it does indeed turn out to be a new, unpredicted, particle.

The UK science community draws vital benefits from EU membership and could lose influence in the event of an exit, says a House of Lords report out this week. UK researchers placed a high value on collaboration opportunities afforded by EU membership. A number also believe the UK would lose its ability to influence EU science policy in the event of leaving - something that's disputed by pro-Brexit campaigners. To debate the ins and outs of being in or out of the EU, Adam is joined by Viscount Matt Ridley, a member of the committee, and Professor Paul Boyle, the Vice Chancellor of Leicester University and former president of Science Europe. Scientists at Aarhus University in Denmark are developing a quantum computer. To help them solve a particular problem, they have turned to human brain power, harnessing our ability to play computer games. The team have designed video games, such as Quantum Moves - that are helping them to understand the problem of 'slosh'- that atoms move about, when moved, like water sloshing in a cup. Many diseases are caused by a particular type of DNA error called a 'point mutation'. In our genomes, the substitution of a single letter of genetic code can be the root cause of diseases such as Alzheimer's, sickle cell anaemia, and a whole range of cancers. Recently, a new technique for editing DNA, called CRISPR, a precise genetic engineering tool, was developed, which might help combat these diseases. The problem is that the cell often reacts to this editing; trying to mend what it perceives as damage to its DNA. This week, David Liu, from Harvard University, published new research showing how his team have managed to switch out a single letter, a base pair, whilst tricking the cell into not correcting this edit.

This week Russian internet billionaire Yuri Milner announced a project to send tiny spaceships to Alpha Centauri. Milner, alongside Stephen Hawking, announced a $100 million project to develop and launch a cloud of spaceships with sails. They'll be powered by giant lasers based on earth, and will fly at one fifth the speed of light. The Breakthrough Starshot project sounds like science fiction - Adam is joined by Professor Andrew Coates from UCL's Mullard Space Science Laboratory to sort the feasible from the fantasy. Space travel is expensive. Scientists and engineers met recently to discuss a way of making it cheaper. Sending men back to the moon to mine it may sound like a hugely costly process, but as reporter Roland Pease discovers, when it comes to future space missions, it might become an essential part of the process. Closer to home than the moon is a section of the atmosphere called the thermosphere that is poorly understood. A European project called QB50 plans to change this, by sending 50 small satellites, known as CubeSats, into orbit this summer. Most of them will sport sensors that can probe the properties of the upper atmosphere. The group building these sensors is led by UCL's Mullard Space Science Laboratory, which will build 14 spectrometers. These will analyse the relative proportions of different types of particles in the thermosphere. Marnie Chesterton finds out how scientists cope with the challenge of building their gadgets smaller and lighter. Many listeners wrote in after a recent piece on solar panels. We had queries about how to store the electricity, and whether PV panels are worth the energetic cost of producing them and what units to use. We put all these questions to Jenny Nelson, Professor of Physics at Imperial College and author of 'The Physics of Solar Cells.'.

This week a "Faraday Discussion" - a unique way of presenting and sharing cutting edge science - is underway at the Royal Society of Chemistry in London looking specifically at Chemistry in the Urban Atmosphere. As Prof Ally Lewis of York University tells Adam Rutherford, atmospheric chemistry is so complex, and detector standards so variable - in particular the cheaper commercial brands - that it can be hard to check whether our environmental policies are working. Whilst local and national governments spend precious public money checking for compliance with a number of common pollutants, atmospheric chemists would like a more investigative approach, looking at the chemistry in action, rather than the end products. Do you suffer in the spring and summer? Allergies are on the increase in the UK. And scientists don't know why. But the environment, and what we breathe from it, is thought to be key. A new app for smartphones called Britain Breathing has been developed by scientists at Manchester University working with allergy sufferers. Hay fever affects millions of Britons but is under-reported and poorly understood. Combining large numbers of reports of symptoms with their location and time could lead to valuable insights. Last December, BBC Inside Science reported on the mothballing of several Carbon Capture and Storage pilot schemes, following withdrawal of government funding. But some work continues. Doug Connelly of the National Oceanographic Centre in Southampton tells Adam about a scheme currently trialling carbon storage in the North Sea, to see whether disused oil and gas fields can be used to store our dangerous emissions. A little over 2200 years ago, Carthaginian general Hannibal Barca infamously led a huge army of elephants and horses across the Alps, almost to the gates of Rome. It has been celebrated as one of the most audacious military campaigns in history, but his exact route has always been subject to debate. This week further results from a consortium of disparate scientists have been published, supporting their preferred route taken by the grand army. Microbiologist Chris Allen from Queen's University talks Adam Rutherford through the "deposition of data", marking the passage of thousands of animals. What is the new evidence? A microbially recalcitrant, precisely dated, phylogenetically relevant layer of euphemism.

The world's second largest floating solar farm has just started generating power. Built on the Queen Elizabeth II reservoir in West London, it's the size of eight football pitches and can provides enough power for 1,800 homes. Its construction was a race against time, because the UK government cuts subsidies for new solar farms from April. Adam Rutherford talks to Leev Harder from Lightsource Renewable Energy about the project. Dr Iain Staffel is a sustainable energy expert at Imperial College London and he explains the main issue with solar: the difficulties in storing the electricity produced until it's needed. A team from Glasgow University has invented a portable gravity detector. Volcanologist Hazel Rymer from the Open University discusses how this cheap and portable device can detect tiny changes in gravity in the ground. She hopes to use this kind of device to monitor what's happening inside volcanoes soon. In New Zealand, the near-extinct kakapo will become the first species to have the genome of every single member sequenced, thanks to a crowd-funded conservation project. Adam Rutherford meets geneticist Peter Dearden, in the Zealandia conservation area in Wellington, to chat about these charming but daft birds, and efforts to save them from extinction. Producers: Marnie Chesterton and Jen Whyntie.

The flu season is running later this year. And it has been unusually virulent. Professor Wendy Barclay, virologist at Imperial College London, tells Tracey Logan about the constant race to keep up with flu mutations in order to build an effective vaccine.Wine has a microbial terroir which is thought to affect its taste. A new paper suggests coffee and chocolate might do too. Aimee Dudley from the Pacific Northwest Diabetes Research Institute in Seattle has studied global populations of yeast found on cacao and coffee beans. She explains that these yeast varieties are genetically diverse. Tracey Logan travels to coffee supplier Union, to meet scientist-turned-coffee-buyer, Steve Macatonia, and unpick the flavours of coffee.In Delft, the world's biggest artificial waves are pitted against a new kind of super-strong sea wall. The Delta Flume team, led by Mark Klein Breteler, has created a giant concrete channel with a wave generator. Reporter Roland Pease turns up in time to see the team testing their artificial waves against a 10 metre dyke.People with cochlear implants hear a degraded version of speech. Using subtitles helps train the brain to understand it faster. Matt Davis and Ed Sohoglu from the Medical Research Council's Cognition and Brain Science Unit in Cambridge suggest that this feeds into a model of how the brain learns called Perception Learning.

Research in Nature this week shows that lost memories in mice can be rescued by reactivating a group of memory cells in the brain called 'engram' cells. The team suggests that their research might prove useful for Alzheimer's patients in the future. Professor John Hardy, neuroscientist at University College London and Dr Prerana Shrestha from the Center for Neural Science at New York University discuss the work with Tracey.The migrating white stork is well-known in folklore as the bringer of babies. In recent years, large numbers of them have decided to stop flying to Africa for winter, and live all year round, feasting on food from landfills in Portugal. Dr Aldina Franco from the University of East Anglia has been studying these birds and talks to Tracey about these adapting birds.A scientist at Royal Holloway University in London has discovered the oldest-known fossil of a pine tree. Howard Falcon-Lang discovered the fossils in Nova Scotia, Canada, and brought some back to his office. 5 years later, he dissolved a sample of what looked like charcoal in acid and discovered charred pine twigs. These date back 140 million years to a time when fires raged across large tracts of land. Reporter Roland Pease visits his lab to look at the samples close up. The research suggests the tree's evolution was shaped in the fiery landscape of the Cretaceous, where oxygen levels were much higher than today, fuelling intense and frequent wildfires. UK Gardeners may have noticed summer flowers blooming at unusual times this winter. Tracey meets up with seed scientist Steve Penfield and crop geneticist Judith Irwin in a greenhouse at the John Innes Centre. They explain how seeds and flowering times are affected temperature changes.

This week in the US, public discussions are taking place into controversial Gain of Function research. Who should decide the limits of studies where scientists make new, deadlier viruses in the laboratory? Dr Filippa Lentzos, biosecurity expert from King's College, London, lists a litany of accidental security breaches from the past. Should we stop this kind of dangerous research, or encourage it, in the interests of national security?Mindfulness is a hot topic at the moment. As part of BBC School Report, students from Connaught School for Girls in Leytonstone have tested themselves to see whether meditation helps with their studies. Tracey Logan discusses the scientific research underpinning this trend with psychologist Claudia Hammond. The Royal Society released a report this week entitled "Parent, Carer, Scientist." The idea is to encourage an environment in research institutions where scientists can have a life as well as a vocation. Professor Ottoline Leyser, Professor of Plant Development and Director of Cambridge University's Sainsbury Laboratory, discusses what needs to change to ensure more female scientists to stay in science.How do snakes move across sand? BBC science reporter Jonathan Webb meets Perrin Schiebel, at the Georgia Institute of Technology. A physicist, she works with a giant sand pit and high-speed cameras, putting snakes through their paces to unpick how they can push their bodies off the sand without sinking into it.

This week is birthday time for the 3000-strong group of 70 year olds who might qualify for the title of longest-serving science guinea pigs. Participants in The National Survey for Health and Development cohort study have been closely monitored since their birth in 1946. Joining Adam Rutherford to discuss how this and other similar studies have influenced our lives, and what data we should collect on today's babies, are the Head of the National Survey for Health and Development at MRC's Unit for Lifelong Health and Ageing at University College London, Professor Diana Kuh, and Professor Debbie Lawlor, programme lead at the Medical Research Council's epidemiology unit at Bristol University. A team of British team has picked up £1 million from The Brain Prize, which is issued by a Danish Charity annually. Tim Bliss, Graham Collingridge and Richard Morris have won for their work on how memories are formed. BBC science reporter Jonathan Webb is a former neuroscientist and brings us up-to-date with the latest thinking on how we remember. Finally, grey hair and mono-brows have been all over the news this week with some follicular genetics. A team from UCL assessed the hair types of several thousand Latin Americans and cross-referenced this with their genomes to see what bits of DNA are associated with those characteristics. They found a set of gene variants - or alleles - some known to us, some new, that appear to be part of the reason we have straight hair or curly, bushy brows or mono-brows. Dr Kaustubh Adhikari from UCL is the lead author on the study. Producer: Jen Whyntie.

Britain faces a referendum on whether to leave Europe. Science, and scientists, often cross borders in collaborations, so what would the implications be for a British exit from the EU? The House of Lords Science and Technology Committee have an ongoing inquiry into how EU membership influences British science. Inside Science condenses the pertinent points. The stem cells that make up our organs 'know' whether they are 'male' or 'female', and that this sexual identity could influence how they grow and behave. Dr Irene Miguel-Aliaga, at the MRC Clinical Sciences Centre at Imperial College London, wanted to ask a very basic question: whether it is just the cells of the sex organs of a fully developed organism that 'know' their sexual identity, or whether this is true of cells in other organs too - and whether that matters. It was previously thought that non-reproductive organs are the same in both sexes, and function differently because of the differences in circulating hormones, but her new research suggests that cells know their sex. At Birmingham University, chemical engineers have built a working prototype of an artificial human colon, the first of its kind. The colon does the last bit of moving your food out of your body, mixing it, squeezing the last few nutrients and excess water out of it. The team want to use it to measure drug delivery to the colon. Talking with your mouth full is an unattractive trait, but for other, non-human, great apes it is a normal part of meal time. The noises recorded by a team at the Max Planck Institute for Ornithology are from the silverback Western lowland Gorilla. Primatologist Eva Luef explains that this humming and singing during meal time is a way of signalling without wasting valuable eating time.

Gravitational waves were announced last week, in what may be the science discovery of the decade. The Ligo detector, the most sensitive instrument on the surface of the planet, detected the ripples given off by the collision of two black holes. Adam Rutherford puts a selection of listener questions to UCL cosmologist Dr Andrew Pontzen.In March 2015, Campbeltown, Glasgow Prestwick, Stornoway, Newquay, Llanbedr and Leuchars were shortlisted by the government as possible sites for a "cosmodrome" or spaceport. With the UK space industry worth an estimated £40 billion by 2030, various stakeholders met for the UK spaceport conference at the Royal Aeronautical Society in London to discuss the progress of the project. What would the impact be for scientists, industry and the public?Big brains have traditionally been considered an advantage. Animals with larger brains are better at using tools, working as a social group and assessing how to react to predators. But when Dr Eric Abelson cross referenced relative brain size against the mammals on the endangered list, he found something surprising. Many animals with the bigger brains are threatened within extinction. He talks to Adam about why that may be.Tim Cockerill, ecologist and adventurer, returns from Papua New Guinea to discuss how one group of indigenous people have decided to work with scientists in order to conserve and study their local environment.

The universe is silent no longer - physicists at the LIGO observatory have detected gravitational waves. LIGO, the Laser Interferometer Gravitational-wave Observatory, with its giant laser beam arms totalling 5 miles across the remote Hanford desert, is the largest lab on the surface of the planet. It was constructed in the Columbia Basin region of south-eastern Washington specifically to detect gravitational waves -- ripples in the fabric of space-time. First predicted a century ago by Einstein in his theory of general relativity, gravitational waves are produced by exotic cosmic events, such as when 2 black holes collide. Scientists have hunted for them for decades with increasingly sensitive equipment. The laser beam tubes of the observatory have proved sensitive enough to detect the signal from deep space as small as a thousandth the diameter of a proton. Tracey and studio guest Dr Andrew Pontzen from UCL examine the science of gravitational waves, and how LIGO is both an eye and an ear on the motion of distant objects. They scrutinise the cutting-edge technology, which has to be of almost unimaginable sensitivity to enable detection of some of the universe's most dramatic events. Inside Science also shines a spotlight on the passion of individuals who have worked for nearly three decades on a single science experiment, inventing a whole new branch of physics in order to prove the last piece of Einstein's theory of general relativity, and to "hear" the universe in a whole new way.

Some much-needed good news for our troubled bees and other pollinators: between 1998 and 2007, the amount of nectar produced from Britain's flowering plants rose by 25%. A new study suggests this may be due to reductions in atmospheric pollution. But researchers looked at records spanning over 80 years, and also found that the UK flowers which provide nectar suffered substantial losses during the 20th century. Considering the services that nectar-feeding pollinators perform for agriculture and our ecosystems, this is something worth knowing. Professor Jane Memmott, ecologist at the University of Bristol, explains how bad things really are for Britain's pollinators and what lessons conservation could learn from her team's latest findings about nectar.In 2014, neuroscientist Dr Phil Kennedy flew to Belize and paid a surgeon to insert electrodes into his otherwise healthy brain, in order to experiment on himself. His aim was to unpick the electrical signals given from his brain during speech. BBC science reporter Jonathan Webb went to his lab in Georgia, US to meet the maverick. Jonathan and Tracey discuss the motivation, scientific outcome and ethics behind Dr Kennedy's highly unusual experiment.The aim of hologram technology, according to Birmingham University researchers, is to make it cheaper, faster and better. Holographic tattoos are a solution they are developing. Currently, holograms are made with lasers and mirrors. Roland Pease went to visit researchers Dr Haider Butt, Bader Al Qattan and Rajib Ahmed in order to make his very own hologram.On 4th February 50 years ago, the Soviet lander Lunar 9 sent a signal back from the moon. Scientists at Jodrell Bank intercepted this and realised that it sounded like a picture image. Professor of Astrophysics at Manchester University Tim O'Brien explains how, with the help of a fax machine borrowed from the Daily Express, British scientists scooped the first pictures of the moon's surface.

The Zika virus is dominating the news this week. The latest data says it's been found in 21 countries so far. The symptoms are generally mild, but the possibility of a link to microcephaly has been raised in Brazil. Microcephaly is a serious condition where children are born with abnormally small heads and sometimes incomplete brain development. Trudie Lang, Professor of Global Health at Oxford University, and virologist Professor Jonathan Ball from Nottingham University discuss what we know so far. All the way from Antarctica our reporter Victoria Gill brings us the latest news about the citizen science project 'Penguin Watch'. Victoria installed new cameras with Dr Tom Hart and collected guano with Hila Levy. Gemma Clucas (Oxford and Southampton University) gives an update on what will happen with the collected data. Back in October we featured a major paper by a team of scientists lead by Dr Andrea Manica from Cambridge University. By comparing the 4500 year-old genome of a prehistoric man called Mota to other genomes from living Africans they had mapped a migration of Middle Eastern farmers back into the whole African continent. This week, colleagues identified an error in the way the original team had processed the data, thus overturning one of the key results. But the rest of the findings remain intact. Andrea talks to us about how and why science must make corrections along the path of progress. Heard a few stories about giant dinosaur fossils lately? Usually the giant A-list superstar fossils get all the attention. But according to curator Mark Carnall, about 90% of the collections are mainly uninteresting specimens. Marnie Chesterton went out to meet Mark at the Museum of Natural History in Oxford. He celebrates fragmentary fossils in his blog 'Underwhelming Fossil Fish of the Month'. Warning: Lower your expectations! Producer: Jen Whyntie Assistant Producer: Julia Lorke.

Our ability to extract DNA from old bones is improving, giving us a much clearer picture of who our ancestors were, and what they did. Two new papers out this week in Nature Communications are filling in some gaps in our knowledge of the history of Britain. One of the pieces of research - led by Professor Dan Bradley from Trinity College Dublin - examines DNA from individuals who died in northeast England at the beginning of the first millennium of the current era. The other paper analyses the genomes of East Anglian people who lived at a similar and slightly later time, and the lead author is Dr Stephan Schiffels. He worked at the Wellcome Trust Sanger Institute near Cambridge at the time of this research, and is now based at the Max Planck Institute for the Science of Human History. Professor Mark Thomas from University College London is a co-author on Dan Bradley's paper and joins Adam Rutherford to discuss this research in the context of its rapidly changing field.Concorde flew its first commercial flight on the 21st January 1976. To mark its 40th birthday, Concorde engineer Christopher Mitchell and Concorde pilot David Rowland talk about the extraordinary aeroplane's scientific and engineering legacy.What looked like an innocent rocky outcrop in the Argentinian desert turned out to be something completely different: An eight foot long femur, belonging to the world's largest dinosaur. Ben Garrod is one of the team who has put together this as yet unnamed behemoth. He talks us through the extraordinary discovery and journey to investigate a new species - and it's only just beginning. The work has been documented as part of the TV programme 'Attenborough & the Giant Dinosaur', due to air at 6.30pm this Sunday 24th Jan on BBC One.Finally, today's headlines indicate that we might have been missing something fairly substantial in our very own solar system: A new ninth planet. However, as BBC Science Correspondent Jonathan Amos tells us, this isn't yet confirmed. With Dr Ellen Stofan, NASA Chief Scientist.Producer: Jen Whyntie.

The 100,000 Genome Project aims to sequence the DNA of 100,000 patients. One of those patients is four-year-old Georgia Walburn-Green. Her symptoms did not fit into any known disease category. Prof Maria Bitner-Glindzicz at University College London used early results from the 100,000 Genome project to diagnose Georgia's condition.Roland Pease reports on helping stem cells survive using a kind of 'blood paint'. By dipping the cells in myoglobin, researchers at Bristol University have found a way to improve both the vigour and survival of stem cells.The expanding nuclear programme in the UK will continue to produce nuclear waste - in lower volumes than previously produced, but we already have a large stockpile that has already been produced over the last 50 years. Countries around the world are facing a similar challenge: What do we do with the waste? Dame Sue Ion, engineer and expert advisor to the nuclear industry, discusses common practices and alternative approaches to nuclear waste disposal.Many dinosaurs had big, iconic features like frills, plates, horns and spines that may have been tools or weapons, but Dr David Hone's (Queen Mary University of London) research on the small, herbivorous dinosaur Protoceratops andrewsi reveals that they may also serve another purpose in the dinosaur society: sexual selection. Could these features be what attracts one dinosaur to another?Producer: Deborah Cohen and Jen Whyntie Assistant Producer: Julia Lorke.

El Niño is releasing vast quantities of heat normally stored in the Pacific, causing floods, droughts and fires. Adam Rutherford discusses the latest with our El Niño expert Roland Pease.This weather event arrives every 2-7 years but it's hard to work out how profound it will be. Back in May last year, the Met Office climate scientist Adam Scaife correctly predicted an El Niño. He returns to give an overview of this phenomenon.How does an altered weather pattern in the Pacific end up altering the weather in Cumbria. Tim Stockdale at the European Centre for Medium-Range Weather Forecasts and Richard Allan at Reading University explain the science behind the current events.The rains are coming to drought-ridden California as a result of El Niño. Jack Stewart explains why this is not entirely a good thing.Professor Sue Page from Leicester University and Professor Martin Wooster from KCL study the Indonesian fires exacerbated by an El Niño event. They describe the devastating effects of these fires. An estimated 15,000 death can be attributed to the previous El Niño burning and it has added 300 million tonnes of carbon dioxide to the atmosphere.

Adam Rutherford and guests oceanographer Dr Helen Czerski, astrophysicist Chris Lintott and zoologist Dr Tim Cockerill share their highlights of the science year and answer listeners' science questions. Producer: Adrian Washbourn.

Since the epic flyby of Pluto in July, NASA has been regularly downloading staggering images from the New Horizons mission. Pluto is not a dead rock, but a geologically active dwarf planet, with tectonic movements, ice plains, glaciers, dunes and cryo-volcanoes. For an end of year update on the observations and outstanding mysteries, Adam meets Alan Stern, the Principal Investigator on New Horizons, who is still marvelling at the success of this humble craft. Scientists have discovered how a potentially useful predatory bacterium called Bdellovibrio protects itself against its own weapons when it invades other bacteria. Professor Liz Sockett discusses how the work offers insights into early steps in the evolution of bacterial predators and how this will help to inform new ways to fight antimicrobial resistance Science stops for no one .So how are researchers nurturing their experiments over the festive period? Marnie Chesterton has gone on the hunt for scientists for whom Christmas Day will be yet another day in the lab.This year there's has been an explosion of papers of using DNA to reconstruct human history. We've invented new techniques for extracting DNA from the long dead, and for analysing ancient genomes. Professor Matthew Cobb from the University of Manchester assesses recent key developments in reconstructing the lives and population structures of ancient civilisations.Producer Adrian Washbourne

Two times shuttle captain, and with 6 months on the ISS, Commander Chris Hadfield is best qualified to pass on his advice to Major Tim Peake about the science and life in general on the International Space Station.Polar bears walk further Polar bears are having to walk further to stay in the same place. As ice melts in the Arctic, the thin ice is blown around by the wind, making it harder for polar bears to stick to their traditional hunting grounds.Elephant Deterrent By combining a seismic element to the infrasound of recordings of elephant alarm calls, researchers hope to finally develop an audio deterrent to keep marauding elephants from destroying farmland in Africa.Tracking air pollution from space The US space agency satellite, Aura has been tracking trends in emissions of nitrogen oxides for over a decade. It's seen big falls in the pollutant in the US and Europe, while at the same time recording significant increases in some developing nations, such as China and Bangladesh.Air pollution Even if the air pollution trends are getting better in the West, the picture is still very complicated. Not least in London, where nitrogen oxides are still at dangerous levels. Added to this is a rise in smoke pollution from the increasing number of wood burning stoves in the city.Human Evolution Gallery at the Natural History Museum A new gallery of Human Evolution at the Natural History Museum opens on Friday 18th December. Adam gets a sneak preview with Professor Chris Stringer and Dr Louise Humphrey. Spanning 7 million years of evolution, the gallery brings together key fossils and recent evidence such as a reconstructed skull and hand of Homo naledi. It builds up a picture of where we come from and what makes us human. And the picture is far more complex than previously thought, with multiple species living at the same time.

Flood modelling As parts of Cumbria and Somerset remain on flood alert, Adam looks at the science that predicts floods. Are our flood defences good enough and is climate change behind the recent cluster of '1 in 100 year' floods? Flood modeller Nick Reynard from the Centre for Ecology and Hydrology explains.What is a scientific model? Prompted by a listener's question, Adam asks scientists what they mean when they say they "modelled the data". He explores the strengths and weaknesses of using models to represent things as diverse as the spin of planets and field choice of skylarks.Magneto-reception Is there a 6th sense? Since the 1960s, it has been generally accepted that animals have a sense of magnetism. This may help explain how some birds are able to migrate huge distances. However, ever since this discovery, the mechanism behind the reception of the Earth's magnetic field has remained a mystery. Scientists don't know which components are responsible for detecting the magnetism, hence the search for 'a biological compass'. The quest has united people from a range of disciplines such as animal behaviourists, chemists and quantum biologists. Are scientists getting any closer to finding the biological compass?Escalator experiment Regular commuters on the London Underground know instinctively to 'stand on the right and walk up on the left' when using the many escalators on the Tube. But in a three week trial at one of the busiest stations - Holborn - Transport for London staff are asking travellers to stand on both sides. The idea is to regulate the flow of traffic. Will it work?Producer: Fiona Roberts.

Science Funding Review In the Comprehensive Spending Review last week, the Government announced its commitment to protect the science budget in 'real terms'. After five years of declining spending on science, this has been welcomed by many in the research community. But a lot of the detail is still to emerge. Adam asks Minister for Universities and Science, Jo Johnson where the extra funds are coming from? Is it a case of money being moved around, between departments or is there really an extra £1.5 billion, over the next 5 years, in the science research pot? Carbon Capture Storage Five years ago, amid much fanfare, the Chancellor of the Exchequer, George Osborne, committed £1 billion to the development of carbon capture and storage - the technology to extract carbon dioxide from the exhaust streams of power stations, and bury it underground. This technology is one strategy for reducing our impact on the climate while keeping coal, oil and gas as options for generating energy. Given the discussions going on right now over in Paris at the United Nations Climate Change Conference, COP 21, this might seem like a suitable commitment for the UK's plans to address global warming. But in the recent Comprehensive Spending Review, the Government have withdrawn the money, effectively ending the current CCS research in the UK. Graphene In contrast, one of the many recent success stories in UK science, graphene, is set to be a focus of research in the Government's plans. Graphene is the world's first truly two dimensional material; incredibly strong, very light and extremely flexible. It is also capable of conducting heat and electricity, so it is a material exciting scientists and industry alike. Since the isolation of graphene in Manchester in 2004 the UK has been at the forefront in graphene research. This year the National Graphene Institute in Manchester was opened, with a remit to link basic, fundamental research to graphene commerce and industry. Producer: Fiona Roberts.

Ancient farmers' genomes New research looking at the DNA of people who lived in Europe as early as 8500 years ago shows signs of evolution, of natural selection, and of how farming has changed Europe in the last few millennia. The huge sample of 230 ancient individuals includes 26 Neolithic people from Anatolia thought to be the very first farmers.Cern's ALICE Experiment Adam visits CERN in Geneva, to see ALICE (A Large Ion Collision Experiment). ALICE is designed to investigate one of the four fundamental forces in the Universe. The strong nuclear force is the most powerful, but only over a very short distance. It is what holds quarks together, and quarks stuck together in the right conformation make neutrons and protons. Protons and neutrons stuck together plus electrons make up atoms, which is what everything is made of.Listeners Questions on Astrophysics Space physicists, Dr. Carole Haswell from the Open University and Dr Andrew Pontzen from UCL answer your questions about the force of gravity, the size of stars, the volume of matter and more.Producer: Fiona Roberts.

Antarctic ice-sheet instability A new study models how the ice sheets in Antarctica will react if greenhouse gases rise at a medium to high rate. They predict the most likely outcome is a rise in global sea level of about 10cm by 2100. Previous research had put this figure at 30cm: this has not been ruled out by the new research, but it's been ruled much less likely. Groundwater The Earth's groundwater has been quantified - it's estimated to be 23 million cubic km. (which is equivalent to the Earth's entire land surface covered in a layer some 180m deep.) However, just 6% of the water is available for our use and to take part in the hydrogeological cycle. That small fraction is referred to as "modern" groundwater: it is extractable because it is near the surface, and can be used to supplement above-ground resources in rivers and lakes. But it's also the most sensitive to over use, climate change and to human contamination. Fluorescent coral Adam visits the National Oceanographic Centre in Southampton to see some fluorescent corals and asks how they can be utilised for medical imaging. Accents How are our accents changing? A three year study at University of Glasgow has found that Scottish accents haven't changed as much as English accents (which have become much more homogenised over the past 100 years). By listening to recordings from first World War Scottish prisoners of war, the Sounds of the City project has noticed that changes to Glaswegian accents have occurred over a much longer time frame than previously thought. But these changes have occurred locally - not in the same way or to the extent that it is thought English accents have evolved. Producer: Fiona Roberts.

Britain's oldest tree changes sex - The science behind the headlines - this week it was reported that the Fortingall Yew in Perthshire (known to be a male tree, over 2-5000 years old) had started to produce berries (female) on one of its branches. Dr. Max Coleman from the Royal Botanic Gardens in Edinburgh explains that sexuality in plants is more fluid than in animals. Cryo-volcanoes on Pluto The latest observations from the New Horizons mission to Pluto show possible volcanic-type structures made from ice. The mountains have what appear to be caldera-like depressions in the top. Unlike volcanoes on Earth, that erupt molten rock, the suspected volcanoes on Pluto, would likely erupt an icy slush of substances such as water, nitrogen, ammonia or methane. Sellafield's plutonium The nuclear reprocessing plant in Cumbria has amassed around 140 tonnes of plutonium on site. This is the largest stockpile of civil plutonium in the world. For now it is being stored without a long-term plan, which is costly and insecure. At some point a decision will need to be taken on how it is dealt with. The estimated clean-up costs are between £90-250 billion, which means the pressure to make the right decision is massive. Should we convert it into useable fuel or get rid of it? And how secure is it in its current state? Ant super-organisms Ants behave as a super-organism when under predation threat - complex chemical communication in rock ants are key to how they behave as a unit to different threats. Producer: Fiona Roberts.

Grid cells and time Animals navigate by calculating their current position based on how long and how far they have travelled and a new study on treadmill-running rats reveals how this happens. Neurons called grid cells collate the information about time and distance to support memory and spatial navigation, even in the absence of visual landmarks. New research by Howard Eichenbaum at Boston University has managed to separate the space and time aspects in these cells challenging currently held views of the role of grid cells in the brain.Boole It's the 200th anniversary of the birth of George Boole. We speak to Professor Des MacHale, his biographer at Cork University, and Dr Mark Hocknull, historian of science at University of Lincoln, where he was born, to uncover Boole's unlikely rise to Professor of Mathematics, given his lack of formal academic training. We discuss the impact of his work at the time, and his legacy for the modern digital age.How your brain shapes your life It weighs 3lbs, takes 25 years to reach maturity and, unique to bits of our bodies, damage to your brain is likely to change who you are. Neuroscientist David Eagleman's new book, The Brain: The Story of You, explores the field of brain research. New technology is providing a flood of data. But what we don't have, according to Eagleman, is the theoretical scaffolding on which to hang this. Why do brains sleep and dream? What is intelligence? What is consciousness?Producer: Fiona Roberts.

Oxygen on comet 67P Molecular oxygen (O2) detected on comet Churymov-Gerasimenko 67P, has scientists baffled. Current models of the formation of our Solar System do not predict conditions that would allow for O2. Bees and antimicrobial drugs The antibacterial properties of honey have been exploited for thousands of years, but now scientists at the University of Cardiff are using honeybees to collect and identify plant-derived drugs which could be used to treat antibiotic resistant hospital pathogens. By screening honey for these plant compounds and identifying the plant through the pollen grains in the honey, researchers can narrow down the active ingredients and even exploit this to get bees to make medicinal honey. Reproducibility of science experiments A lot of science experiments, when redone, produce different result. Professor Dorothy Bishop chaired a report, out this week, on reproducibility in science. She explains why reproducibility is important, why failures are due to many factors beyond fraud, and how measures, such as pre-registration and collaboration on large expensive experiments, can help make science more robust and repeatable. Reintroduction of beavers In National Mammal Week and the Mammal Society UK is giving a whole day of its national conference at Exeter University over to the reintroduction of European beavers. In February last year a group of beavers were spotted apparently having been living and breeding on the River Otter in Devon for quite some time. By March this year an attempt by DEFRA to remove them had been challenged by local campaigners and now a 5 year watch period has been set up over which time the effects of the beavers on the ecosystem will be monitored. But how might the renegade rodents have been influencing the ecosystem? And with another project currently underway to reintroduce the Pine Marten, a large relative of the weasel, to Wales is there a new public focus on mammal reintroductions in the UK? Producer: Fiona Roberts

Animal experiments Scientists are changing the way they measure animals used in research. The most recent Home Office report not only shows the numbers of animals used, it also grades how much each animal suffered. Dr Sara Wells from MRC talks to Adam about this new measure, and also the fact that the overall number of animals used in 2014 has declined for the first time in years. Bees and diesel The polluting power of diesel has been getting a lot of press recently. Now, new research has shown that the volatile nitrogen oxides in diesel exhaust (NOx) are preventing bees from finding their food flowers. The diesel chemically alters some of the most common floral scent compounds, rendering them unrecognisable to bees and other insect pollinators. The effect adds to the suite of environmental factors impacting bee survival. Sense Ocean Adam visits the National oceanography Centre in Southampton where they are working on Sense Ocean - A big Europe-wide project which is monitoring what is in the world's oceans. Professor Matt Mowlem, is Head of the Ocean Technology and engineering group, and he is in charge of making sensors, which measure the chemical and biological nature of sea water from small platforms and vehicles. Readability of IPCC Report A paper in Nature Climate change last week scored the IPCC Summary for Policy Makers report, very low for 'readability', Adam discusses the trade-off between writing science that is right, and writing science that is understandable. Producer: Fiona Roberts.

In a special programme to mark, amongst other things, the centenary of Albert Einstein's General Theory of Relativity, Adam Rutherford is joined by The Film Programme's Francine Stock to explore the theme of time-travel - in science, in film and as film. With studio guest, science writer Marcus Chown, they'll discuss time-machines - as imagined by scientists and film-makers; the grandfather of all paradoxes; the notion of the multiverse and how the pioneers of cinema created their own 'time-machines' through the art of editing. And to mark Back the Future Day, otherwise known as 21 October 2015, they talk to director Robert Zemeckis about how and why he imagined a future with hover-boards but, oddly, no smart phones.Producers: Stephen Hughes and Rami Tzabar.

As evidence grows about the vulnerability of our ocean corals to climate change, what's often overlooked are the more subtle changes in the ocean waters that contribute to coral resilience. Adam visits Southampton's Oceanography Centre where new research is showing how an imbalance of nutrients in reef waters is increasing the vulnerability of reef corals to high water temperatures which could help direct future coastal management.The long awaited hunt for gravitational waves gets underway as the Laser Interferometer Gravitational Wave Observatory (LIGO) in the United States begins its first observational run. The waves, generated by some of the most dramatic events in space such as the explosion of stars and the merging of two black holes, were first postulated by Einstein in 1916. So far they've never been detected but if LIGO is successful it'll not only provide proof of Einstein's Theory of Relativity but also provide the first direct evidence of the existence of black holes.And Adam meets theoretical physicist Carlo Rovelli whose new book Seven Brief Lessons on Physics examines in seven short essays how 20th century physics is shaping our world view. In Italy, it's outsold 50 Shades of Grey and the Pope's Encyclical and has now been translated into English. What's been the key to its success?

A special edition recorded in front of an audience at Write on Kew, the Royal Botanical Garden's new literary festival. Adam Rutherford examines the science behind the global challenges and innovative solutions to preserving the essential biodiversity of the planet. From new perspectives on how plant populations can be made more resilient, to the remarkable genetic diversity of plants just being revealed by new analytical techniques, to coffee - and how one of our most prolific yet threatened commodities be protected from a changing climate . Do we need a radical new approach - are the large scale climate fixes offered by geoengineering the right solution? Adam Rutherford is joined by panellists: Kew's Director of Science, Kathy Willis; evolutionary botanist, Ilia Leitch, Kew's research leader in plant resources, Aaron Davis and author Oliver Morton.Producer: Adrian Washbourne.

Adam Rutherford and panellists Helen Czerski, Andrew Pontzen and Nick Crumpton answer listeners' science questions: What's the best way to become fossilised when you die? What are the most genetically different animals than can breed, either in the wild or in captivity? Why are there no animals with green fur? If one of the fundamental constants, like the speed of light, was 50% faster how would it affect our universe and would the universe even exist? Can we infer where the edge of our expanding universe is from its age - is that even a sensible question? Would you experience zero gravity at the centre of the Earth? At a busy airport are the chances of meeting and finding each other better if one person stays put in a space while the other person searches, or if both parties wander around searching? Find out the answers to these and more.

This summer, the spaceship New Horizons sped past Pluto at 30,000mph, snapping photographs as it went. The pictures sent back this week have transformed our view of this former planet. It isn't a dead rock; it is geologically active, with ice volcanoes and plenty of terrestrial movement. Dr Cathy Olkin from the mission explains what has got her team so excited.The space elevator, first dreamt up in the 19th century, is a tower tall enough to reach space. The sci-fi concept took a step towards reality recently, when the Canadian engineering company Thoth were granted a patent for an inflatable tower 20 kilometres high. Adam speaks to Thoth's Chief Engineer Ben Quine about the viability and possibilities of this project.It's the season when 30 million European songbirds fly south for the winter. Lower profile and harder to study are the billions of insects that take a similar journey. Dr Jason Chapman from Rothamsted Research tells Adam how to study animals that are too small to tagCan you measure imagination? A team from the Hungry Mind Lab at Goldsmiths University in London thinks you can. The goal of their two year project is to produce an app that can improve imagination by training it. To improve it, first they need to reliably measure it. Adam tries out their new test.

Tracey Logan talks to Professor Chris Stringer about the discovery a new human ancestor, Homo Naledi. With ape and human like features its age isn't known yet but could it be evidence of the origin of the genus homo? Astronauts' spines can elongate as much as 7 centimetres in space because of the loss of gravity potentially causing severe back problems. Tracey talks to David Green from Kings College, London about a new elastic suit he has helped develop to mimic the effects of gravity. What exactly is quantum biology? Marnie Chesterton talks to Jim Al Khalili and Johnjoe McFadden authors of 'Life on the Edge, The coming of age of Quantum Biology which is short-listed for the Royal Society Winton Book prize. Tracey meets Dr Qadeer Arshad at Charing Cross hospital to try a new potential cure for sea sickness. By applying an electric current to the scalp is it possible to prevent the symptoms of nausea? A limited number of tickets for Write on Kew are available by emailing [email protected] with BBC Inside Science in the subject line.

Tracey Logan investigates the latest science news. Roland Pease reports on recent warnings that we're heading for one of the most severe El Ninos on record which could distort weather patterns around the world. Spongey sphagnum moss provides a protective layer to peat lands but in the bogs of the Peak District industrial and urban air pollution has killed nearly all the moss. This means the peat lands can erode releasing tonnes of ancient carbon. Tracey talks to horticultural ecologist, Neal Wright about his technique for creating tiny gel beads of sphagnum moss to spray on the moors to help restore their peat lands back to health. Marnie Chesterton talks to John Butterworth about his book, 'Smashing Physics' which is another short-listed entry for the Royal Society Winton book prize. He talks about the highs and lows of the discovery of the Higgs Boson and why CERN might soon be creating dark matter. Tracey talks to Toby Shannon, from the Institute of Physics about the International Year of Light citizen science project to measure air pollution using an iPhone.

Why the expansion of the paleolithic brain was powered by cooked carbohydrates. Gareth Mitchell talks to Professor of Evolutionary Genetics, Mark Thomas, about the difficulties of establishing what our ancestors ate. More than half the world's corals grow in deep, cold waters, many around the shores of the British Isles. But a new study shows they are under severe threat from ocean acidification caused by increased levels of carbon dioxide. Gareth talks to Professor of Marine Biology, Murray Roberts, from Heriot Watt University about why these corals could all be gone by the end of the 21st century. This week's short-listed Royal Society Winton Prize book is Life's Greatest Secret: The Race to Crack the Genetic Code. Marnie Chesterton talks to the author Matthew Cobb. BBC Science and environment reporter, Jonathan Webb, joins Gareth from the American Chemical Society meeting in Boston to talk about why the grime on buildings could be a new source of air pollution and why carbon dioxide in the atmosphere could be used to make carbon fibres.

As Scotland announces it ban on GM crops and with the current post of chief scientific adviser for Scotland vacant, Adam talks to the previous post holder, Professor Muffy Calder about the role of science advice to government and her reaction to news of the ban. The Earth's magnetic field is weakening which could be a sign that the magnetic poles are soon due to flip. Daniel Lathrop and team at Maryland University are trying to model the Earth's magnetic field using a large molten globe of sodium. Should we be worried if a flip is on the cards? Royal Society Winton book prize short-list: Science writer, David Adam, author of 'The Man Who Couldn't Stop' talks to Marnie Chesterton about his experience of Obsessive Compulsive Disorder. Adam hears about the birth of a new galaxy seen for the very first time. He talks to Chris Martin from Caltech about his latest galactic research published in Nature.

The New Horizons probe is now millions of miles past Pluto, journeying throgh the Kuiper Belt, but still sending back gigabytes of data coming in via the Deep Space Network. Its latest image of Pluto's surface was released by NASA on Wednesday, of huge mountains emerging from an otherwise flat plain, Dr John Spencer one of the lead scientists on New Horizons, a planetary geologist, discusses what's to be read into the surface images captured over the last weekA new paper just published in Nature Geoscience shows that in 2013, which was a slightly cooler summer than average, arctic ice had grown, by 41% on the previous year. The study, uses data from ESA's Cryosat 2, which incorporates not just the surface area of ice, but the all-important number - the volume Adam examines the results with Rachel Tilling from University College London.Computing has taken a Sci fI step forward this month. Professor Miguel Nicollelis of Duke University, a specialist in brain machine interface experiments, has linked together the brains of four individual rats in order to use the computational power of their brains to carry out tasks including image processing, data retrieval, and even weather predictions. But could this have a therapeutic use in brain damage? Professor Andrew Jackson from Newcastle University, an expert in called 'neural prosthetics' examines the potential.Across the animal kingdom, signals advertising when females are at their most fertile can be pretty striking. Humans are more subtle, though plenty of studies have shown that female behaviour and physiology does change during the menstrual cycle. A new study by Dr Robert Burriss from Northumbria University suggests that faces may be advertising a woman's most fertile time of the month. But are the traits too subtle for most people to notice?Producer Adrian Washbourne.

It's billed as the last great encounter in planetary exploration. For the past nine years the New Horizons spacecraft has travelled 5bn km (3bn miles) to get to Pluto On July 14th it performed its historic fly-by encounter with the dwarf planet. Adam Rutherford examines the first images from the New Horizon's probe and hears the first interpretations from mission leaders and scientists at the NASA New Horizon's space centre as the data arrives back to earth. Expect new light to be shed on the Solar System's underworld as first impression s reveal Pluto to be a champagne coloured body with 11000 ft ice mountains and surprisingly smooth surfaces that suggests recent geological activity For people who grew up with the idea that there were "nine planets", this is the moment they get to complete the set. Robotic probes have been to all the others, even the distant Uranus and Neptune. Pluto is the last of the "classical nine" to receive a visit. Dame Jocelyn Bell Burnell discusses how this 2,300km-wide ice-covered rock was demoted in 2006 to the status of mere "dwarf planet", but as "Pluto killer" Mike Brown argues, this shouldn't dull our enthusiasm. As Adam Rutherford reveals, nothing about this corner of the solar system has been straightforward. Little is known about Pluto's creation -but as the New Horizons probe passed Pluto for this first close up of the dwarf planet , scientists anticipate new insights into the evolution of our solar system and even earth's early history. With contributions from mission scientists Alan Stern, Fran Bagenell, Joel Parker and astronomer Mark Showalter. Updates too as interpretations rapidly develop, from BBC correspondent Jonathan Amos and astrophysicist Chris Lintott. Producer Adrian Washbourne.

Adam Rutherford talks to Emily Holmes from the Medical Research Council’s Cognition and Brain Sciences Unit in Cambridge, about two new studies on preventing intrusive memories. She discusses why stopping someone from sleeping after seeing a lab based film of traumatic events like a news reel or car crash may actually stop people from forming intrusive memories about those films. This offers an intriguing insight in to the role that sleep has in consolidating intrusive and possibly traumatic memories. She also explains how if memories of a traumatic event are laid down, why playing a computer game like Tetris could disrupt that memory and stop it from becoming intrusive. Silent Aircraft: The Davies report recently recommended a new, third runway should be built at Heathrow airport but as flight numbers increase how quiet can planes of the future become? Adam talks to Jeremy Astley from Southampton University and Michael Carley from Bath University about where the noise in jet engines comes from, how engineering can make them quieter and will the silent aircraft initiative ever make a truly silent aircraft. Nuclear Fusion. For decades scientists have tried to harness the power of the Sun to smash atomic nuclei together to create a clean, limitless energy source from nuclear fusion. Marnie Chesterton talks to scientists from Tokomak energy about their new design for a Tokomak machine that has already exceeded previous records. Could it be a vital step forward in the quest for nuclear fusion on Earth? New Horizons: On 14th July 2015 the spaceship, New Horizons will complete its 10 year mission to flyby Pluto. BBC Science correspondent Jonathan Amos gives Adam a preview and tells him why he's so excited about the mission and what they hope to discover about the darker regions of our Solar System.

Rothamsted Research in Hertfordshire has just finished trials of a new way to repel aphids from wheat. It's a clever system, that takes a gene for a pheromone, called E beta farnesene, from peppermint, and inserts it into wheat. Aphids let off E Beta Farnesene when they are under attack or when a dead bug is detected, and idea was to have the wheat produce the chemical alarm itself. In the lab, the plants had driven aphids away in their droves. But in the field, where controlled lab conditions are not present, there was no measurable reduction. So what's gone wrong? Adam speaks to spoke to plant geneticist to Dr Gia Aradottir who worked on the Rothamsted trial and Professor Mike Bevan of the John Innes Institute. Top biologists have recently met to launch the National Institutes for Bioscience, the N.I.B, a star-studded partnership of eight great British biological Institutes, such as the Roslin- former home of Dolly the Sheep - and the world's longest running agricultural research station Rothamsted Research. George Freeman MP, Britain's first Minister for Life Sciences, provided a bit of glamour to mark the occasion. Tracey Logan was there to meet the key scientists and to ask the Minister about the ambition and role of the N.I.B. A team of scientists has just revealed how they've used genetics to scan the peoples of the world - and amazingly of extinct people from prehistory - to see who can smell what. They've used one particular olfactory receptor, called OR7D4, to build up a global map of what people can smell. Adam Rutherford speaks to Professor Matthew Cobb, from Manchester University to discuss how the different peoples of the world - including long extinct humans - smell different things. Why are parrots such good copycats? A team in Duke University in the US thinks that they have uncovered the exact spot in the brain that gives the parrot this ability. Professor Erich Jarvis studies the genes involved in the structure of bird-brains, and discusses some ideas about how those neurons have developed through a combination of behaviour and genetics.

Malaria is the single greatest cause of death that humankind has ever experienced, and continues to be a colossal burden on the health of people all over the world. We've had various treatments over the years, but all of them have been weakened when Plasmodium - the parasite that causes the disease - evolves resistance. So the hunt is perpetually on for novel antimalarial drugs. This month, a new one is published in the journal Nature. Adam Rutherford talks to Professor Ian Gilbert from the Drug Discovery Unit at Dundee University to discuss with him how the new compound attacks the plasmodium parasite to prove effective. Radio 3 is currently in the midst of a season focusing on all aspects of the Classical Voice. Science is playing a growing insightful role in understanding how to get the best out of the singing voice. Many singers base their careers on a particular quality of voice, and that sometimes can sound as though we're imposing a lot of strain on our vocal cords. We hear from Julian McGlashan, an Ear Nose and Throat specialist at Nottingham University Hospitals who has taken singers and placed a video endoscope down each of their throats to observe how their vocal tracts behave differently according to the style they sing. And David Howard head of the Audio Lab at York University, discusses how new technology is helping us understand how it's possible for a singer's voice to cut above the sound of an orchestra and still be heard at the back of a vast auditorium. Species might seem like an obvious way to classify organisms, and one way we define species is by reproductive isolation - If you can't breed with it, it's another species. If we successfully bred with Neanderthals, and produced fertile offspring, surely that means that they must be the same species as us? Adam talks to Professor of evolutionary genetics from UCL Mark Thomas to navigate through the messy world of human species. Producer Adrian Washbourne.

The ALMA telescope array in the Atacama Desert is one of the most sensitive earth based telescopes. It has now captured images of the very first galaxies. Adam talks to Dr Mark Swinbank of Durham University who's part of the team who've unleashed data this week from that universal hinterland that's set to fill in the missing gaps in our understanding of the evolution of the universe.The European Parliament voted this week to place a moratorium on new licences for member states to frack for shale gas until proven safe for the environment. But how dangerous is fracking? A set of articles out this week in the journal Seismological Research Letters attempts to address and dispel some of the myths and misconceptions about fracking, and to get to the root of the very real, increasing frequency of seismic activity. US Geologist Justin Rubinstein and University of Strathclyde geologist Zoe Shipton discuss the evidenceAs global temperatures increase Ice Core scientists searching for clues to Earth's past climatic history face a ticking clock to gather enough core samples before they melt. Only a tiny amount of mountain glacial ice has ever been collected and studied, and in 2016 ice cores from the Alps will be moved to safer storage in Nature's freezer - a giant vault in Antarctica. Marnie Chesterton meets Ice Core researchers from British Antarctic Survey to find out why they need this archive.A new paper shows the first recorded instances of alcohol drinking in wild chimpanzees. Tanya Humle from the University of Kent describes the novel behaviour. With anthropologist Professor Catherine Hill, Dr Humle discusses whether "wild" chimp research is even possible in an age when human and chimp habitats overlap.Producer Adrian Washbourne.

Think of earthquake cities and places like San Francisco or Los Angeles spring to mind. But London is also seismically active. 200 years ago, there was an earthquake under Trafalgar Square. Dr Richard Ghail from Imperial College London meets Adam Rutherford on the banks of the Thames to discuss the fault lines under their feet and what engineering challenges this poses. In the beginning, there were chemicals. A geological blink of the eye later, there was LUCA, the last universal common ancestor; a complex cell. How the chemistry became biology is one of the biggest mysteries in science. New studies from University of North Carolina researchers chips away at this unknown, offering evidence on how the genetic code developed in two stages. Adam meets Dr Matt Powner, a chemist at University College London studying the origins of life, to find out how researchers try to answer this fundamental question. How do we know what our landscape used to landscape? Pollen, from buried mud layers, offers a picture of sorts. By gathering tiny pollen grains, and identifying the plant species at different ages, Dr Ralph Fyfe from Plymouth University builds up a picture of European landscapes thousands of years ago. Peak deforestation happened several thousand years ago, as our pyromaniacal ancestors started forest fires to clear land for agriculture. Roland Pease reports. A plague is killing thousands of common frogs in ponds across the UK. Ranavirus causes ulcers on the skin and haemorrhaging. A team at Exeter University has noticed that ponds with fish are more likely to have an outbreak of this virus. Amber Griffiths urges Radio 4 listeners to leave their ponds to the wildlife, and keep frogs and goldfish apart.

We're becoming more reliant on robots to assist in hostile zones from extinguishing forest fires to bomb disposal to decontaminating nuclear facilities. But whereas humans can quickly adapt to injuries, current robots cannot 'think outside the box' to find a new behaviour when they get damaged. Tracey Logan speaks to computer scientist Jeff Clune who's developed a new way to allow robots to adapt to damage in less than two minutes. It will enable more robust, effective, autonomous robots, and may shed light on the principles that animals use to adapt to injury.

El Nino is a weather event that happens every 5 years. It leaves Europe largely unscathed but causes havoc around the southern hemisphere. El Nino causes droughts, floods and has even been linked to an increased incidence of war. And yet it is surprisingly hard to predict. Adam speaks to Professor Adam Scaife, from the Met Office, about unpicking the science from weather chaos. Echolocation is the ability to sense objects using reflected sound. A handful of animal species do this - most bats, some whales and even a few humans. Some blind people use echolocation to navigate the world they can't see. Some make a clicking sound as they walk. Others use the sound of their footfall. In fact, all humans, sighted and unsighted, do it. Adam meets BBC's Damon Rose, who is blind, and they compare skills. Marnie Chesterton travels to Southampton University's Institute of Sound and Vibration Research to meet Daniel Rowan. His team have recently isolated some of the factors necessary to echolocate. The work involved an anechoic chamber - the quietest place on earth and the sound equivalent of nothing. Last week Adam gave the incorrect reason for why we have seasons. Dr Laura Rogers, a physics teacher, puts him right. Dr Rhys Jones, star of BBC TV's Wildlife Patrol talks to Adam about the origin of snakes. A recent paper from a team in Yale hypothesises a common ancestor with tiny hind legs and nocturnal habits. Adam questions why 3400 species of snake have evolved to not have legs, when millions of other animals find them so useful.

Many diseases strike harder and more often in the winter, including major inflammatory conditions such as Type 1 diabetes, multiple sclerosis and rheumatoid arthritis. New research out this week has uncovered the reasons why: it turns out that our immune responses are heavily influenced by the seasons. Professor John Todd who led this new global study discusses the results and how this could influence the way we administer medicines in future. Organisms generate energy in all sorts of ways and it can happen in all sorts of weird places, such as deep sea hydrothermal vents, where bacteria takes nasty stuff such as Hydrogen Sulphide, and turn it into useful stuff such as amino acids. This is called chemosynthesis. But it turns out that it doesn't just happen in dark corners of the ocean. As tubeworm expert Nick Higgs explains we are learning that chemosynthesis is everywhere. Major Tim Peake begins his six-month mission to the International Space Station in November,. Ever since its inception, the question of 'what the ISS is for?' has been asked.. So, what sort of science does it deliver? Richard Hollingham reports from Alabama, in a secret NASA research bunker. Two years ago, a team led by Nick Goldman at the European Bioinformatics Institute in Cambridge successfully took a collection of important cultural artefacts, encoded them digitally, and then wrote them in DNA. These included Martin Luther King's "I have a dream" speech, and all the Shakespearean sonnets. He's now collaborated with artist Charlotte Jarvis to encode a new musical composition which will also form a new art installation Music of the Spheres. DNA's ability to store complex digital data appears close to a reality. Could it hold the key to permanent long term storage for anything? Producer Adrian Washbourne.

Adam Rutherford investigates the news in science and science in the news.

Nepalese Earthquake The earthquake that struck central Nepal last weekend measured 7.8 in magnitude and has affected up to 1.4 million people. Inside Science reporter Roland Pease joins Adam to discuss the topography of Nepal, and its vulnerability to earthquakes. We hear from Roger Bilham, a seismologist at University of Colorado, and Alex Densmore from Earthquakes without Frontiers on seismic activity in the Himalayas and the difficulty in measuring the scale of the disaster. Monkey Nuts Capuchin monkeys use stone tools to crack open nuts they want to eat. New research by Madhur Mangalam and Dorothy Fragaszy has shown that they moderate the force they use to open these nuts based on whether the nut shows any cracks from previous strikes. This motor skill demonstrates their dexterity as they are picking the optimal way to complete their task. Scientists hope these findings could help to explain the differences in cognitive processes between non-human primates and hominids who learnt to shape stone tools. Maritime light pollution Around a fifth of the world's coasts are illuminated at night by lights and as LEDs grow in popularity we can expect to see these areas get brighter. But until recently the effects of this light on the marine ecology was a relatively unknown and understudied phenomenon. Adam talks to Thomas Davies whose research published this week has highlighted how light is affecting marine organisms; attracting organisms like keel worms whilst repelling others. Wellcome Collection & Bacteria Light Artists, microbiologists, doctors and geneticists will gather at the Wellcome Collection in London this weekend for the Bacteria Light Lab, an event exploring how light is providing the tools for discovering more about bacteria and infections, part of the 'On Light' weekend at Wellcome Collection. Inside Science went along to meet artist Anna Dumitriu and Dr Nicola Fawcett and view- what appear at first glance - somewhat esoteric looking pieces of art which are actually shedding light on the hidden kingdom of microbiology. Producer: Adrian Washbourne.

The Yanomami people are Amerindians thought to have been completely isolated since their ancestors arrived in South America after the last ice-age. Now a multinational team of scientists has more than made contact with them - it's persuaded them to donate samples of their faeces hoping to find good bacteria and useful genes that people living Western lifestyles are thought to have lost. Maria-Gloria Dominguez-Bello, a microbiologist at the New York University School of Medicine, explains how this could provide valuable insight into causes and treatment of escalating metabolic and inflammatory diseases in the western world. With news this week of a British financier's arrest over alleged involvement in the Flash Crash of 2010, what are the pros and cons of the next new era of superfast computer-led trading? It's now set to happen even faster thanks to a higher speed, transatlantic communications cable that goes live this summer. Tracey Logan discusses new technological developments that get close to trading at the speed of light with science writer Mark Buchanan and hedge fund scientist Matthew Killeya. It's thought that light and dark are the main factors influencing our body clock, but in new research published this week the blue colour of twilight could be the major factor that keeps our clocks entrained to the 24 hour world around us. Tim Brown of Manchester University discusses why it's quality rather than quantity of light that's important. And there's a visit to the Geological Society in London to mark the 200th anniversary of the first geological map of England, Wales and Southern Scotland. It was compiled by the humble canal surveyor William Smith - but as geological historians Tom Sharp and Hugh Torrens reveal, Smith's ingenuity was to revolutionise mineral prospecting and help shape the scientific and economic development of Britain in the midst of industrialisation. Producer Adrian Washbourne.

On 25th April 1990, the Hubble Space Telescope (HST) was released into space from the Discovery space shuttle. Though off to a famously bumpy start - the first images sent by Hubble were blurry due to a flaw with one of the mirrors - it has been collecting data that has been contributing towards shaping our understanding of the cosmos and it continues to do so. The HST is operated by the Space Telescope Science Institute located at Johns Hopkins University in Baltimore, Maryland. Tracey Logan speaks to Mario Livio, an astrophysicist at the institute, who shares his perspective on the Hubble mission for the last 25 years and talks about ongoing Hubble projects. At the cutting edge of cosmology research, data recorded by Hubble is used to improve our understanding of such things as the universe's rate of expansion and theories about the hitherto elusive dark matter. A team led by University of Arizona astronomer Peter Milne has found hints that cast a new light on the currently accepted view that the universe is expanding at an increasingly faster rate. Could it be that a particular type of supernova - type 1A - is not the perfect cosmological "Standard Candle" we've thus far thought it to be? Another group of astronomers, led by Dr Richard Massey at the University of Durham, used data from Hubble in their attempt to unravel the elusive nature of dark matter. Dr Massey talks to Tracey Logan about how having a particular angle on a collision between galaxies some 1.4 billion light years away has allowed for potentially the first ever observation of dark matter colliding with itself. We still don't know what the nature of dark matter is, but this could be our first knowledge of it interacting with anything, possibly implying "Dark Forces" at work. This new research is put into perspective by Dr Malcom Fairbairn, who has revived the neglected telescope on the roof of King's College London. He talks to Tracey Logan about how these recent findings could herald genuinely new areas of physics. Meanwhile, closer to earth rocks, what could or should be done about the danger of asteroid impact? This week in Frascati, Italy, the European Space Agency hosts the 2015 Planetary Defence Conference. Detlef Koschny, head of ESA's Near Earth Object section, speaks to Tracey Logan about coordinating global efforts. Producer: Marnie Chesterton.

This month sees the end of NASA's MESSENGER mission to Mercury. It's been the first mission to the sun's closest planet since Mariner 10 flew by in the mid-1970s. Lucie Green speaks to geologist Professor Pete Schultz of Brown University about the orbiter's 4 year surveillance and how new observations of this under explored world are shedding light on the planet's mysterious dark cratered surface.Virtual experiences are coming closer and closer to reality as both sound and vision, and even smell, become convincing. But without the sense of touch you'll never have the full experience. A team at Bristol University has now managed to generate the feeling of pressure projected directly onto your bare, empty hands. Its system enables you to feel invisible interfaces, textures and virtual objects through the use of ultrasound. Roland Pease gets a hands on experience.One of the biggest challenges in artificial intelligence is conquering a computer's so-called "catastrophic forgetting": as soon as a new skill is learned others get crowded out, which makes artificial computer brains one trick ponies. Jeff Clune of Wyoming University directs the Evolving Artificial Intelligence Lab and has tested the idea that computer brains could evolve to work in the same way as human brains - in a modular fashion. He shows how by doing so, it's possible to learn more and forget less.And there's a visit to the Ion Beam Centre at University of Surrey where, in conjunction with a project to restore the Rosslyn chapel near Edinburgh, scientists have provided a new development in stained glass conservation - scrutinising the glass contents at the subatomic level using a narrow beam of accelerated charged particles, to literally decode the exquisite features lost to the naked eye. Lucie Green caught up with the Centre's director, Roger Webb.Producer Adrian Washbourne.

Invasive alien species from the cursed Signal Crayfish to the scourge of gardeners, the Japanese Knotweed, are considered some of the biggest threats to biodiversity. This year the EU has launched new legislation that attempts to limit their spread. But how big a threat are they to ecosystems? Science writer Fred Pearce author of The New Wild argues that ecologists are committed to protecting pristine environments from alien invaders, when we should be embracing the changing ecology that invasive species enable. Adam Rutherford discusses the conflicting approaches to invasive species with Fred Pearce and Dr Helen Roy - a scientist at the Centre for Ecology and Hydrology. Corals make up only 0.1% of the ocean floors, but account for up to a quarter of all marine life. A new exhibition at The Natural History Museum is showcasing some of the work of the Catlin Seaview Survey, which is compiling a huge pictorial health check of various reefs to act as a snapshot against which all future reef changes can be compared. We hear from Dr Ken Johnson, the Museum's main coral researcher, and Professor Ove Hoegh-Guldberg, - Chief Scientist for the Catlin Seaview Survey. There's a big gap in understanding the evolution of our brains. But experts, from geologists to computer scientists by way of marine biologists have recently been meeting at the Royal Society, for a symposium entitled 'Origin and Evolution of the Nervous System' to assess what evidence there is. Roland Pease reports. And we explore a new advance in virtual reality. Anil Seth, professor of Consciousness Studies at the Sackler Centre at Sussex University has been experimenting with our sense of self, and our experience of the world, by using a hi tech headset combined with 360 degree cameras to transport your whole experience to a different space. Virtual reality becomes "substitutional" reality'. Producer Adrian Washbourne.

The Romans, Vikings and Normans ruled Britain for many years, but few left their genetic calling cards behind in the DNA of today's mainland Caucasian population. That's one of the insights from the most comprehensive analysis yet of the genetic make-up of the UK's white British population. As the study's lead author Peter Donnelly explains it's produced some big surprises, not least how in contrast, the Anglo Saxons invasion was to account for up to 40% of the genetic mix in much of southern Britain. Much of Britain's current historical information is from a relatively small subset of people, but a genetic study like this sheds light on the history of the masses. The Royal Botanical Gardens Kew is currently at the forefront of trialling drone technology to map and locate remote vegetation The aim is to examine plant health and deforestation in detail, particularly in inaccessible areas around the globe. The team led by Justin Moat and Oliver Whaley have recently returned from Peru, where they've examined the fragile ecosystem threatened by mining in the Lomas region. BBC Inside Science's Sue Nelson was deployed to join the Kew team for a Drone test run. As our energy needs become greater, the impetus to tap the sun's energy directly becomes ever more urgent. A new paper published this month has cracked one of the barriers to efficient conversion of water into oxygen and hydrogen, which plants of course do naturally. Adam Rutherford speaks to Nathan Lewis at California's Institute of Technology who has developed an electrically conductive film that could enable devises to harness sunlight to split water into hydrogen. Chemist Andrea Sella assesses how close we are to achieving artificial photosynthesis and solar fuels. And ahead of tomorrow's solar eclipse, Adam speaks to solar scientist Dr Huw Morgan from the University of Aberystwyth, who together with his colleagues in Svalbard is going to use those precious seconds to answer one of the great enduring mysteries of the sun: why is the corona, the fiery crown around the orb, is a great deal hotter than the sun itself? Producer Adrian Washbourne.

Today CERN announced that on 23rd March the largest single machine the world has ever seen gets plugged in, switched on, and rebooted after a 2 year rest. The Large Hadron Collider was crashing particles at energies just off the speed of light, and in doing so, simulating the universe in its neonatal form. It will be shortly achieving energies twice as great as before and as Adam Rutherford hears from particle physicists Tara Shears and Malcolm Fairbairn, vast new opportunities for discovery will open up In The Archers, the current devastation caused by the rising of the River Am is a stark reminder of the impact of last year's floods and the unpredictable nature of river channels. But a new study argues that if we're to get a better grip on the hazard posed by a river - and even predict the likelihood it will flood - an overlooked factor needs to be embraced. Louise Slater from Queen Mary University of London discusses the missing piece in the puzzle NASA's Space Launch System, or SLS, will be capable of taking astronauts beyond low Earth orbit for the first time since the end of the Apollo era in 1972.Its first - unmanned - launch is due in 2018 and yesterday the first ground test on two of the massive boosters was successfully completed . BBC Future Space Correspondent, Richard Hollingham, reports from NASA's assembly facility to get the measure of this interstellar behemoth. The golden age of violin making was dominated by master violinmaking families from the 17th and 18th centuries but what accounts for their revered acoustic power? Adam speaks to violin virtuoso Tasmin Little and hears of a new study by acoustician Nicholas Makris from Massachusetts Institute of Technology, who's scanned, measured and documented the violin's changing dimensions to try and account for the unique fullness of sound during this era. Producer Adrian Washbourne.

How does the brain lay down memory? For decades the limits of microscopes have meant that a detailed look at the way brain cells encode particular learned skills and events has proved elusive. But in a report published this week a team of researchers has identified how changes in specific connections encode a particular behavioural response. Adam Rutherford talks to Tony Zador of Cold Spring Harbour laboratories who's become the first to crack a piece of the neural code for learning and memory which could have profound medical insights. 350 years ago this week, the world's first scientific journal was published. Philosophical Transactions began by drawing together various letters and reviews that cemented the origin of modern science by publishing Isaac Newton, Christopher Wren and other founding members of the esteemed Royal Society. Historian Dr Aileen Fyfe discusses the key moments in the journal's evolution and its legacy today. There's a look at the ongoing representation of women in science following on from a recent report examining the Royal Society's 2014 university research fellows of which only 2 out of 43 were women. The Society's President Sir Paul Nurse discusses how the imbalance in this and in science more generally should be addressed. NASA's Dawn spacecraft is about to arrive in the orbit around the dwarf planet Ceres and will be the first mission ever to successfully visit a dwarf planet. As the spacecraft spirals closer, images have shown numerous craters and mysterious bright spots that scientists believe could reveal how Ceres formed and offer new clues to the origins of our solar system. Adam talks to the mission's deputy scientist Carol Raymond on the latest interpretations of what's currently being observed. Producer: Adrian Washbourne.

A computer system has taught itself how to play dozens of video games. AI researchers claim this is a significant step toward machine intelligence, because the learning process is similar to how humans learn. The program, labelled DQN by its creators at Google DeepMind, performed as well as or better than humans at assorted Atari video games, such as Breakout, and Pong. This style of "Deep learning" is useful because it can be more readily applied to real world scenarios. As Adam Rutherford discovers,it's a short step from mastering a driving simulation game to self-driving cars. Desalination to produce fresh drinking water is on the rise, but the bi-products of the process - acidic brine and carbon dioxide, are a growing environmental problem Adam Rutherford talks to Dr Philip Davies who's devised a new idea for treating brine from desalination plants that could help curb carbon dioxide emissions and go a long way towards addressing acidification of our oceans. Plymouth music festival, Biomusic, features a new work by composer Eduardo Miranda, inspired by a fungus mould. Roland Pease meets the musical pioneer who finds music in biological tissues A new exhibition at the Wellcome Foundation explores the history, science and art of forensic medicine, from the crime scene to the courtroom. Adam heads down to 'Forensics: the anatomy of crime' for a tour with forensic scientist Dr Angela Gallop, who worked on high profile cases including the murders of both Damilola Taylor and Stephen Lawrence, and also meets exhibition curator Lucy Shanahan.

Alzheimer's disease is becoming increasingly common as the global population ages. It is estimated that currently 44 million victims of Alzheimer's dementia exist in the world and that this will grow to more than 100 million cases by 2050. The announcement this week of the creation of the Drug Discovery Alliance - a network of labs to fast track dementia treatment aims to address the urgent need to identify drugs that prevent, slow the progression, or improve the symptoms of Alzheimer's. But what are the scientific hurdles and what's missing in our knowledge in fuelling an ambition to achieve a disease modifying therapy for dementia? Adam Rutherford speaks to Cambridge University neuroscientist Rick Livesey, and to Eric Karran, Director of Research at Alzheimer's UKHow is it possible to remember something initially and then change your account of the experience later on? Possibly, giant swathes of your own personal history are partially fictional if not completely false. The problem isn't that our memory is bad, but that we believe it isn't. Adam talks to forensic psychologist Julia Shaw whose astonishing new research examines the ability to implant completely made-up rich false memories into ordinary people in a lab setting and points to circumstances under which police officers can extract false confessions.There's a visit to the UK's synchrotron light source at Harwell in Oxfordshire which since it started operations in 2007 has illuminating research on subjects ranging from Egyptology to virology and this year is opening its doors to the publicAdam meets Mark Kelly, one of NASA's twin astronauts taking part in a year-long space experiment to examine the impact of space travel using identical twins as subjects. With one twin orbiting on the International Space Station whilst the other remains confined to Earth, the aim is to examine how individuals with the same genetic profile respond to radically different environments - in particular the genomics of humans as they prepare to move away from their home planet.Producer: Adrian Washbourne.

Adam Rutherford explores new insights into what lies at the very centre of the Earth. New research from China and the US suggests that the innermost core of our planet, far from being a homogenous iron structure has another, distinct region at its centre. He talks to the study's lead researcher Xiangdong Song and to geophysicist Simon Redfern about what this inner-inner core could tell us about the very long history of the Earth and the long suspected swings in the earth's magnetic field. Professor Andrea Sella, from University College London is a recipient of the Royal Society's Michael Faraday Prize, in recognition, like Faraday himself, of exemplary science communication to the lay public. Andrea gave his prize lecture this week, describing chemistry as one of the 'crowning intellectual achievements of our age'. How justified is the claim? What have chemists ever done for us? The sea forms the basis of ecosystems and industries, and so even subtle changes to the waters could have serious knock on effects. Dr Susan Fitzer from the University of Glasgow has been wading into Scottish lochs to study shelled creatures; they form a vital basis for marine ecosystems and the global food industry. But what effects could ocean acidification have on this vital organism? And to mark Darwin Day Adam Rutherford examines the origins of Creationism and its most recent variation Intelligent Design. Why do opinion polls in the US routinely find that about half of the population denies the truth of Darwin's theory and believes instead that humans were created supernaturally by God at some point within the last few thousand years? He hears from historian Thomas Dixon, and from Eugenie Scott, former director of the National Centre for Science Education - a US organisation committed to keeping evolution (and now climate change) in the US schools' curriculum. Producer: Adrian Washbourne.

As Helen MacDonald's "H is for Hawk" secures 2014's Book of the Year at the Costa Awards, a paper appears describing the hunting tactics of the Northern Goshawk, quite literally, from a birds' eye view. Suzanne Amador Kane of Haverford College in the US describes her work analyzing footage from tiny cameras mounted on the head of the predatory raptor.The Planck Consortium releases yet more findings from the very beginning of the universe. A new age for the very first stars confirms our best models of the universe. But analysis of the dust in our own galaxy edges out the possibility that last year's BICEP2 announcement did in fact represent evidence of inflation and the first observed primordial gravitational waves.And in the last two weeks, two giants of the twentieth century passed away. Science writer Philip Ball shares his thoughts on the lives of Carl Djerassi, father (he preferred mother) of the contraceptive pill, and Charles Townes, known as father of the Laser.Producer Alex Mansfield.

We all remember the floods across much of central and southern England this time last year, and the devastating effect they had on people's lives and livelihoods. Today, a group of researchers at Cardiff University published a report on how people's perception of climate change has evolved in the wake of the floods. To what extent has our belief in man-made climate change altered? Do we now regard last year's events as a sign of things to come? Adam Rutherford talks to Nick Pidgeon from Cardiff University's School of Psychology who led this UK wide study Earlier this week an international group of climate scientists, geographers and ecologists met at the Stockholm Resilience Centre in Sweden to wrangle how we can practically make the best of the Anthropocene - the new geological epoch that many consider that we now find ourselves in. Gaia Vince author of Adventures in the Anthropocene, reports from the Stockholm meeting At the UK's Satellite Application Catapult in Harwell, a project has been unveiled that seeks to offer real time data on the world's fishing fleet to help governments police illegal fishing. Pulling together data from shipping registers, satellite images, radar and ships' own transponders, Eyes on the Sea automatically scans for suspicious activity and can alert human users and allow them to see what ships are up to. The Pew Charitable Trusts hope that vessels carrying illegal cargoes can then be tracked across the ocean, and any port receiving them would know where they had been and what they had been up to. How complex cells evolved is a mystery. Current theories on the evolutionary jump, between 1 and 2 billion years ago, from life forms based on a simple prokaryote cell to the complex multiple eukaryote cells with a cell nucleus and a host of complex internal machinery, fails to explain much of what we see within animal, plant and fungi cells today. Adam talks to Buzz Baum a cell biologist at University College London who has devised a new testable model which appears to explain one of biology's most basic questions. Producer: Adrian Washbourne.

It is likely that scientists will soon engineer strains of "friendly" bacteria which are genetically recoded to be better than the ones we currently use in food production. The sorts of bacteria we use in cheese or yoghurt could soon be made to be resistant to all viruses, for example. But what if the GM bacteria were to escape into the wild? Researchers writing in the Journal Nature propose this week a mechanism by which GMO's could be made to be dependent on substances that do not occur in nature. That way, if they escaped, they would perish and die. George Church, of Harvard Medical School, tells Adam Rutherford about the way bacteria - and possibly eventually plant and animal cells - could be engineered to have such a "failsafe" included, thus allowing us to deploy GM in a range of applications outside of high security laboratories. Adam reports from this week's launch in Paris of the International Year of Light marking 100 years since Einstein's Theory of General Relativity. Amongst the cultural and scientific events at UNESCO in Paris, Nobel Prize winner Bill Philips explains how using lasers can achieve the most accurate atomic clocks imaginable and we hear how Google X is embracing new ways to manipulate light to ignite some of the team's futuristic technologies And as the global decline in coral reefs continues as a result of human activity, Adam talks to Hawaii based biologist Mary Hagedorn who is using unusual techniques normally adopted for fertility clinics, to store and regrow coral species that are in danger Producer: Adrian Washbourne.

This year is the Food and Agriculture Organisation's International Year of Soils. Adam Rutherford, ably assisted by Manchester University's Richard Bardgett, takes a look at new research seeking to further our understanding of soil behaviour that determines much of our existence. A handful of soil contains many tens of thousands of different species of microbial life, all competing to the death with each other for nutrients and resources. Yet most of those species are very poorly understood, because hitherto scientists have only been able to grow a small percentage of them in the lab. Last week's announcement of a new class of antibiotic - teixobactin - owes a lot to soil; Two buckets of it from the back garden of one of the researchers. Kim Lewis of Northeastern University in the US describes the new technique that could open up the whole biodiversity of a clump of soil to future medicines. Meanwhile, Monsanto, Novozyme and Morrone Bio in the US are just some of the big agricultural corporations exploring what useful microbes could be spread on seeds and crops to increase yields and reduce the needs for fertilizers. Soils, apart from feeding us and helping us fight disease, also have a crucial regulatory role in our climate. Sue Nelson reports on a new soil moisture monitoring network being set up in the UK that uses cosmic rays to measure the water content. The Cosmic-ray Soil Moisture Observing System, COSMOS-UK, is being set up by the CEH, based out of Edinburgh. On a global scale, soils are a hugely important reservoir of carbon. Iain Hartley of the University of Exeter talks about the vast amounts of carbon - more than all the carbon in all the trees and air - held in frozen soils in the far northern reaches of the earth. If these vast plains of permafrost were to melt in a warming world, the positive feedback loop caused by the resulting methane and CO2 released could be a bigger problem than many of our climate models allow for. But could we manage the soils beneath our feet better? David Manning of Newcastle University suggests that minerals could be added to brownfield (urban) soils to help them capture and sequester staggering amounts of CO2 from the air to help us offset anthropogenic emissions. Producer Adrian Washbourne.

Adam Rutherford investigates the news in science and science in the news. This week's announcement of the discovery of 8 planets lying within the habitable zones of their stars has again raised the prospect of an earth like planet existing outside our solar system, But if we're to understand how "earth like" these exoplanets really are, we need to gain vital clues from earth's "evil twin" Venus argues environmental engineer Richard Ghail. Adam Rutherford hears about his proposed new mission to Venus - a planet orbiter to examine the surface and atmosphere that will allow us to understand why Venus has evolved so differently from earth despite their apparent sisterlike characteristics In the more immediate future science correspondent Jonathan Amos looks ahead to some of the highlights in astronomy and physics we can expect in 2015 - from the switch on of the newly energised Large Hadron Collider, and the imminent results of the successful Rosetta mission to the comet 67P, to the long awaited flyby this summer to capture images of Pluto. Roland Pease reports on a revolutionary method of controlling microscopic objects using sonics. As we move further into nanoscale technologies - electronic, mechanical and biological, and often a combination of all three - this could potentially offer a solution to manipulating structures, many of which are quite fragile at this scale. And ten years on from the shock of the South East Asian Tsunami that was to cost the lives of over 220 000 people Adam Rutherford speaks to Dave Tappin of the British Geological Survey, one of the first marine geologists who went to assess the cause of this seismic event. What have we learned in the intervening years? Producer Adrian Washbourne.

Microplastics For the first time, scientists have studied the abundance of microplastics in deep sea sediments They have found that tiny fibres of plastic are everywhere and that levels found in the ocean sediments are 4 times higher than in contaminated sea-surface waters. Marine debris, mostly consisting of plastic, is a global problem, negatively impacting wildlife, tourism and shipping. However, despite the durability of plastic, and the exponential increase in its production, there was a considerable proportion of the manufactured plastic that was unaccounted for. But now scientists have found that deep-sea sediments are a likely sink for microplastics. Holey Ice You'd have thought, given how much water and ice there is around, that we'd know pretty much all there is to know about them. Among the notable facts is that ice is less dense than water - which is why it floats on your pond rather than sinking to the bottom. But like carbon - which exists in two distinct forms, diamond and graphite - the molecules in solid H2O can be packed in many different ways. And this week, scientists have found another completely different form of ice, which is perhaps stranger than all the others. Overeating Why do some people overeat? In order to find out, brave scientists tucked into 9000 calorie meals. Vesalius Andreas Vesalius, the founder of the modern science of anatomy was born 500 years ago, on the 31st December 1514. He was a proponent of, and yet, a strong critic of the ancient Greek physician Galen, who implied human anatomy from animal dissections. Vesalius challenged physicians and medical scholars to get their hands dirty and carry out dissections themselves. Producer: Fiona Roberts.

Where does the Earth's water come from? It's thought that it arrived from space, carried by comets. But recent research suggests otherwise. Professor Katrin Altwegg is principal investigator in charge of Rosina - the tool on the recent Rosetta mission that is charged with answering this mystery. DNA can survive a trip into space, according to a recent experiment. Dr Lewis Dartnell, an astrobiologist from Leicester University, explains the implications. What sounds do the oceans make? Anand Jagatia reports. Dr Julius Piercy from the University of Essex listens to coral reefs. And his recent work could help us harness sounds to help restore damaged and dying coral reefs. This week, the new Nobel laureates head to Stockholm to pick up their medals. Among them is Norwegian neuroscientist Professor May-Britt Moser. The question on nobody's lips; what was she wearing? Which is a shame because she wore a Matthew Hubble dress featuring Grid Cells - our brain's positioning system. Discovering these grid cells won May Britt her Nobel prize. Polymer scientist Professor Tony Ryan from University of Sheffield talks fashion and science with Adam Rutherford. Producer: Beth Eastwood.

A NASA space capsule, Orion, that could transport humans to Mars is due to make its maiden flight. Given that this is a first outing, there will be no people aboard. The capsule will orbit the earth twice in four and a half hours, before splashing down in the Pacific. BBC correspondent Jonathan Amos is on location at Cape Canaveral and gives Adam the latest news. This is a step towards a crewed mission to Mars. But how do humans cope with being confined for the 8 months it takes to get there? The European Space Agency studied this question in 2010. 6 volunteers were shut up in a replica space shuttle for over a year. Engineer Diego Urbina was one of them. He shares his thoughts on taking part in a fake Mars mission. Philip Holliger from the MRC Laboratory of Molecular Biology in Cambridge heads the team that two years ago built XNA, a set of genetic molecules that behave just like DNA, but are man-made. Like DNA, those XNAs didn't actually do that much, but this week, the team has published a paper where they have got them working. These are the first synthetic enzymes on Earth. Back in 2012, a shallow grave was uncovered underneath a car park in Leicester. Evidence suggested the skeleton in it was King Richard the Third. Finally this week, the DNA confirmation by geneticist Turi King is in. And something is rotten in the state of his lineage. Kevin Schurer, historian, and Richard Buckley, the lead archaeologist on the dig, talk us through the DNA anomaly that hints at infidelity in the royal line.

Food Standards Agency report reveals 70% of supermarket chicken contaminated. Chicken: It's the nation's favourite meat. But today, a report released by the Food Standards Agency has revealed that around three quarters of that chicken is infected by campylobacter - a family of bacteria, 12 species of which are known to cause food poisoning. The estimated cost to the UK economy is £900 million per year. All supermarkets are implicated and all supply chains too. It doesn't cause outbreaks and thorough cooking kills all the bugs. Professor Hugh Pennington tells Dr Adam Rutherford why campylobacter is such a tough bug to crack. Can machines think? Neuroscientist, chess master and world-champion gamer, Demis Hassabis is this week's winner of the Royal Society's Mullard Award. In 2011, he founded an AI company, Deep Mind which was acquired by Google earlier this year for £400million.He tells Adam why he believes one of the best tests for artificial intelligence is an ability to learn how to play computer games. Why scientists study sex Sex between humans has long been something of a taboo for scientists. But the Institute of Sexology is tackling it head-on. It's a new exhibition at London's Wellcome Collection, a frank exploration of sex and the scientists who've studied it for the past century or so. Tracey Logan went to preview the display, and asked: Why do scientists study sex? Australopithecus discovery 40 years on 23rd November 2014 was a significant 40th birthday. Or, to be a bit more precise, it was a 3 million, 200 thousand and 40th birthday. On that day in 1974, Donald Johanson and his team in Ethiopia discovered the fossilised remains of AL 288-1, who became universally known as Lucy. Don talks to Adam Rutherford about the young woman who changed his life. Producer: Anna Buckley & Fiona Roberts Assistant Producer: Jen Whyntie.

Philae lander detects organic molecules on Comet 67P Rosetta scientist, Professor Monica Grady from the Open University discusses the latest news from last week's historic comet mission. Philae, the Rosetta robot probe, made history last week when she finally landed on the surface of Comet 67P. But she ended up lying on her side, and only in partial sunlight. Her batteries were on borrowed time. After around 60 hours, Philae powered down, and went into hibernation mode. However, her instruments harvested some data and now the first results are in. UK-led crowdfunded Moon mission Lunar Mission One aims to land a robotic spacecraft on the unexplored lunar South Pole by 2024. It's a space mission with a difference: it could be funded by you. For a small fee supporters can send a human hair to the Moon in a Blue Peter-style time capsule. And the spacecraft will drill up to 100 metres below the surface to ask questions about the Moon's origin, aiming to find out more about the minerals that exist there, several of which are potentially valuable. Our reporter Sue Nelson went to the British Interplanetary Society's Reinventing Space conference in London to hear more. The Selfish Gene debate As another bout of biological warfare breaks out between two scientific superpowers, Adam Rutherford gets to grips with evolutionary theory, with social insect expert Professor Adam Hart. He hears from Richard Dawkins and E.O. Wilson and finds out why, after forty years of promoting the idea of kin selection, E O Wilson now dismisses the whole idea as 'rhetoric'. Presenter: Adam Rutherford Producer: Anna Buckley Assistant Producer: Jen Whyntie.

Rosetta After a nail-biting, bumpy, bouncy landing, European Space Agency's Rosetta probe - 'Philae' -lands on the comet 67P. It's already collecting data and beaming back some very impressive images of this dusty, icy space projectile. BBC Space correspondent Jonathan Amos fills us in on the latest news.Thought-controlled genes Brainwaves from human participants activated a light, which in turn switches on specific genes in mice. In this proof of concept study, Professor Martin Fussenegger hopes that one day this technology could be used to control pain, pre-empt epileptic seizures, or in fact communicate with people who have locked in syndrome. It's another example of two very exciting techniques - brain machine interfacing and optogenetics.Arecibo Message Anniversary 40 years ago, on 16 Nov 1974, a message designed to inform intelligent alien civilisations about human existence was beamed into space. Whilst Frank Drake's binary picture message was primarily put together to show the capabilities of the upgraded Arecibo radio telescope in Puerto Rico, it has inspired interest and enthusiasm around the world. Veteran of subsequent space message projects Dr Carolyn Porco joins Adam to talk about how space science has progressed in the interim decades, and what these ventures mean to humankind.Biophonic Life Sound installation "The Sounds of Others: A Biophonic Line", by artist Marcus Coates is currently delighting visitors to Manchester's Museum of Science and Industry. It explores the sounds of animals, from field crickets to humpback whales. By speeding and slowing each sound, his work reveals unimagined connections between species, and unearths common patterns and forms that would normally be beyond the reach of the human ear. The Sounds of Others looks for commonality between the human and non-human worlds, through sound. Marcus Coates, and collaborator wildlife sound-recordist Geoff Sample talk Adam through some of the surprising sounds of nature. Can you tell a pack of children from red deer? Or Marcus from a Lion? And is there a reason for these connections?Producer: Fiona Roberts.

What is ageing? In 1900, the global average life expectancy was 31, today it's 70, and the number of people over 85 in the UK is predicted to double in the next 20 years. How has ageing evolved, and do we know what is happening in our cells as we age? Professor Richard Faragher, University of Brighton, explains. Sticking plaster-like needle replacement Microneedles on a sticking-plaster-like patch may be the painless and safe way doctors will test for drugs and infections, and give vaccinations in the future. Roland Pease tries an alternative to the traditional injection at Queen's University Belfast with Dr Ryan Donnelly. Science of fire It's November, and these are the days when you may well have a smouldering bonfire in your back garden. Marnie Chesterton meets scientists whose lives are devoted to the behaviour of fire. Comet landing mission nears The Rosetta Mission is entering the final stages before landing on a comet. By this time next week, we will know if the European Space Agency has successfully achieved what could be an extraordinary feat. Paolo Ferri, Head of Mission Operations at the European Space Agency, outlines the challenge. Dr Stronzo and other cases Dr Stronzo Bestiale made his debut in the world of scientific publications in 1987, authoring a paper entitled 'Diffusion in a periodic Lorentz gas', in the Journal of Statistical Physics. However, he doesn't exist. This phantom physicist is not an isolated incident: Mike Holderness at New Scientist has been tracking scientific author apparitions for some time. Producer: Marnie Chesterton Assistant Producer: Jen Whyntie.

It's the nearest and most dominant object in our night sky, and has inspired artists, astronauts and astronomers. But fundamental questions remain about our only natural satellite. Where does the Moon come from? Although humans first walked on the Moon over four decades ago, we still know surprisingly little about the lunar body's origin. Samples returned by the Apollo missions have somewhat confounded scientists' ideas about how the Moon was formed. Its presence is thought to be due to another planet colliding with the early Earth, causing an extraordinary giant impact, and in the process, forming the Moon. But, analysing chemicals in Apollo's rock samples has revealed that the Moon could be much more similar to Earth itself than any potential impactor. Geochemist Professor Alex Halliday of the University of Oxford, and Dr Jeff Andrews-Hanna, Colorado School of Mines - who is analysing the results from NASA's Gravity Recovery and Interior Laboratory (GRAIL) lunar mission - discuss the theories and evidence to-date. Are we going back? Settling the question of the Moon's origin seems likely to require more data - which, in turn, requires more missions. BBC Science correspondent Jonathan Amos tells us about the rationale and future prospects for a return to the Moon, including the Google Lunar XPrize. As the Moon's commercial prospects are considered, who controls conservation of our only natural satellite? If commerce is driving a return to the Moon, who owns any resources that may be found in the lunar regolith? Dr Saskia Vermeylen of the Environment Centre at Lancaster University is researching the legality of claiming this extra-terrestrial frontier. Producer: Jen Whyntie.

It's 10 Years since an unusual skeleton was unearthed on the island of Flores. This species, Homo floresiensis, dubbed 'the Hobbit' because of its short stature, offered a whole new picture of human evolution and has been causing divisions among scientists ever since. Lucie visits Professor Chris Stringer in the Natural History Museum to pick over the bones of a controversial find. Tall parents tend to have tall children. We already know that height is genetic. Less well known is how various genes control the growing process. Recent research from the University of Exeter found nearly 700 genetic variants that play a role in influencing a person's height. Professor Tim Frayling, a lead author, explains how the work, which involve scanning more than a quarter of a million genomes, could help with disease, forensics and predicting a child's adult height. Great ball of fire. The Sun throws out more than just light and heat; for solar scientists, it is also a source of many mysteries. Why is the surface of the sun less hot than its corona, or outer atmosphere? New research using the NASA satellite telescope, IRIS, or the Interface Region Imaging Spectrograph is providing new insights. Earlier this month, a group of more than 100 snail experts (malacologists) from across Europe gathered in Cambridge to discuss the latest research into molluscs - the group of animals that includes everything from squid and octopus in the seas to slugs and snails on land. After three days of lectures, the malacologists were let loose in the Cambridge Botanic Gardens. Reporter Helen Scales went with them on a snail hunt. Producer - Fiona Roberts.

Ebola Outbreak As the World Health Organisation announces that the situation in Guinea, Liberia and Sierra Leone is deteriorating, with widespread and persistent transmission of Ebola Virus Disease, the UK has introduced screening measures at Heathrow airport for passengers arriving from Ebola-affected countries. How has this particular outbreak become so widespread, and where did it start? Lucie Green discusses the source, spread and science of Ebola with Jonathan Ball, Professor of Molecular Virology at the University of Nottingham.Ada Lovelace Day Leading the charge in inspiring and celebrating women scientists, technologists and mathematicians is 19th century computer programmer Ada Lovelace. Daughter of poet Lord Byron, collaborator with inventor Charles Babbage, and accomplished mathematician herself, October 14th has been set aside for Ada Lovelace Day. Event founder Suw Charman-Anderson tells us more.Space Weather The Met Office Space Weather Operations Centre is designed to protect the UK from severe problems caused by space weather. It's been known since 1859 that weather in space can cause problems on Earth, but scientists say our growing dependence on technology puts us at greater risk. Our satellites, power grids and radio signals are all vulnerable to damage from extreme space weather events. Lucie Green heads down to the new space weather centre in Exeter, to see how they monitor the sun's activity, and how that translates into an extra-terrestrial forecast.Producers: Fiona Roberts & Marnie Chesterton Assistant Producer: Jen Whyntie.

Nobel Prizes 2014 The annual Nobel Prizes for Physiology or Medicine, Physics and Chemistry were announced this week. The Nobel Prize for Physiology or Medicine has been awarded to UK-based researcher Prof John O'Keefe as well as May-Britt Moser and Edvard Moser who discovered the brain's "GPS system". They discovered how the brain knows where we are and is able to navigate from one place to another. Their findings may help to explain why Alzheimer's disease patients cannot recognise their surroundings. The 2014 Nobel Prize for physics has been awarded to Professors Isamu Akasaki, Hiroshi Amano and Shuji Nakamura in Japan and the US, for the invention of blue light emitting diodes (LEDs). This enabled a new generation of bright, energy-efficient white lamps, as well as colour LED screens. The 2014 Nobel Prize in Chemistry has been awarded to Eric Betzig, Stefan Hell and William Moerner for improving the resolution of optical microscopes. This type of microscope had previously been held back by the presumed limitation that obtaining a better resolution than half the wavelength of light would be impossible. But the laureates used fluorescence to extend the limits of the light microscope, allowing scientists to see things at much higher levels of resolution. GAUGE The UK has a database for the amount of greenhouse gases we emit each year - usually measured in Gigatonnes of carbon. It's compiled by adding up emissions from various individual sources - be it a coal-fired power station or a wetland bog. This amount is used worldwide, but it is an estimate. A project called Greenhouse gas UK and Global Emissions, or GAUGE, is - for the first time - verifying these estimates by measuring what's in the atmosphere on a much larger scale. Genetics and Diabetes Type 2 diabetes is globally the fastest growing chronic disease. The World Health Organisation estimates more than 300 million people are currently afflicted, rising to more than half a billion by 2030. It might seem on the surface to be a disease with a simple cause - eat too much & exercise too little - and the basic foundation is a relative lack of the hormone insulin. But as with most illnesses, it's much more complicated, not least because a large number of disease processes are happening all at once. In 2010, a particular gene variant was associated with around 40% of Type 2 diabetics - not directly causal, but this so-called 'risk variant' increases the chance of developing the condition if you have the wrong lifestyle. Research published in the journal Science Translational Medicine this week identifies a drug called yohimbine as a potential treatment to help Type 2 diabetics, one that targets this specific genetic make-up. UK Fungus Day October 12th is UK Fungus Day, a chance for us to celebrate these cryptic, often microscopic, but essential organisms. Usually hidden away inside plants or in soil (or if you're unlucky, in between your toes), fungi have largely been growing below scientists' radars for centuries. Mycologists still don't know anything close to the true number of fungi that exist on the planet. About a hundred thousand have been formally identified, but it's estimated that anywhere from half a million to ten million species may exist. This dwarfs, by several orders of magnitude, how many mammals there are on Earth. And, increasingly, we're realising quite how crucial fungi are to the functioning of our ecosystems. Head of Mycology at The Royal Botanic Gardens Kew, Bryn Dentinger, explains how valuable fungi really are. Producer: Fiona Roberts Assistant Producer: Jen Whyntie.

Royal Society investigates the decline in their awards to female scientists Last week, the UK's national science academy, the Royal Society, announced its latest round of University Research Fellows (URFs). And they are almost all fellows - in the male sense of the word. Out of 43 new posts, only two of them are women. These positions are for early-career, post-doctoral researchers. But, at the top of the tree, fewer than one in ten science professors are women, and one of the top UK scientific accolades - a Royal Society Fellowship - is held by only one in twenty. To their credit, The Royal Society were "horrified" by this latest round, and their president, Sir Paul Nurse, immediately called for a full investigation into how this happened, saying "this sends out a bad message to young female scientists". Our reporter Tracey Logan asks why Royal Society grants are so important to young scientists, and whether this year's number of female recipients is a sign of gender bias on the awarding committees, or just a statistical blip in a fair process? And Adam Rutherford meets Professor Julia Higgins to hear the latest just after participating in a diversity working group meeting at the Royal Society in London. Getting science out from behind paywalls You pay for science research via your taxes, but you may not get to see the results unless you pay again to read the journals that publish them. With two major UK science publishers, the Royal Society publishing and Nature, announcing one apiece of their journals are going fully open access -broadly, free for anyone to read online - we're discussing the way science makes it from the lab to the public, via the ever controversial system of publishing and peer review. Adam is joined by Fiona Godlee, Editor of the British Medical Journal; Lesley Anson, Chief Editor of Nature Communications; and Chris Lintott, Professor of Astrophysics and Citizen Science Lead at the University of Oxford. Producer: Fiona Roberts Assistant Producer: Jen Whyntie.

BICEP - gravitational waves and dust One of the biggest scientific claims of 2014 has received another set-back. In March this year, the BICEP2 research team claimed it had found a swirling pattern in the sky left by the rapid expansion of space just fractions of a second after the Big Bang. This announcement was quickly criticised by others, who thought the group had underestimated the confounding effects of dust in our own galaxy. And now, new analysis from the European Space Agency's Planck satellite suggests dust found in our own galaxy may have confounded what was thought to be a universal revelation. India's Mars satellite enters orbit India has successfully put a satellite into orbit around Mars, becoming the fourth nation or geo-bloc to do so. Following a few teething troubles with a planned engine burn shortly after launch on 5 November 2013, and a long journey, the Mangalyaan probe has started sending back images of the Red Planet. It is the first time a maiden voyage to Mars has entered orbit successfully and it is the cheapest mission to-date. Science of language Professor Steven Pinker talks to Adam Rutherford about the language of scientists and the science of language. He has a new book out, "The Sense of Style: The Thinking Person's Guide to Writing in the 21st Century", discussing how the latest research on linguistics and cognitive science can improve writing. The Anatomical Venus Adam visits the Wellcome Collection to see an 18th-Century Florentine Wax Venus - complete with removable abdominal organs. He discusses our preoccupation with death, with Joanna Ebenstein. And finds out if these beautiful, if slightly unnerving, statues were the cutting edge of anatomical learning, or a gory sideshow.

European Ancestry New genetic investigation of ancient human remains, combined with archaeological evidence, is shedding new light on the origins of the early European populations. The international team has provided a detailed analysis of waves of immigration from the near east into Europe, and the emerging agricultural practices that came with it, which has come to dominate the traditional practices of indigenous residents. CERN - Artificial retina The human eye and the parts of the brain that process images are second to none when it comes to pattern recognition and concentrating on the important images and ignoring the rest. They have inspired physicists to create a processor that can analyse particle collisions 400 times faster than any other device. In these collisions, protons, that is, ordinary matter, are smashed against protons at close to the speed of light. These processes may produce new particles and help scientists understand matter's mirror - antimatter. Professor Tara Shears, a particle physicist at the University of Liverpool, explains how this algorithm could help sift through data from collisions at the Large Hadron Collider at CERN. Graphene plaster Since it was discovered 10 years ago, the wonder material graphene has taken the world by storm. What's not to like about it? A sheet of carbon one-atom thick, it was the first two-dimensional material discovered. It's stronger than steel, conducts electricity better than copper. We are told it will be used in touch screens of the future. It may be the secret to miniaturising electronics when current chip technology runs out of steam. But at the other end of the technology market a team at Surrey University has found it useful to blend graphene with rubber bands to make cheap effective bio-sensors. Penguins In a new citizen science project, 'penguinologists' are asking the public to classify images of penguin colonies in Antarctica, to help the team monitor their health. Thousands of images taken by remote cameras monitoring over 30 colonies around the Southern Ocean are being posted online. We hear why penguins are at risk from habitat and climate change and what the public can do to help. Producer: Fiona Roberts.

Jack the Ripper "identified" Some of us are morbidly fascinated by the legend of Jack the Ripper - not the world's first serial killer, but the one that coincided with the birth of mass media, and set the ghoulish tone for the 20th century's obsession with murderers. This week a shawl acquired at an auction in 2007 is in the spotlight. Claimed to be found in 1888 at the murder scene of a woman asserted to be the fourth victim of the supposed Ripper, DNA evidence from the fabric is stated to imply one of the most plausible suspects - Aaron Kosminski. However, there are many problems with this "identification" sequence - some historical, some legal, and some scientific. Adam Rutherford focuses on the science by speaking to Jari Louhelainen, a forensic geneticist at Liverpool John Moores University, who produced the forensic analysis. Jon Wetton, another forensic geneticist at the University of Leicester, offers broader insight into how DNA can be used in detecting crime. Future of Scottish science Scottish science has a rich history: Alexander Fleming, James Watt, Dolly the sheep and much, much more. This week, with the upcoming referendum on independence, Dr Adam Rutherford takes the opportunity to look at the future of science in Scotland. He's joined by scientists representing the Academics for Yes and Better Together campaigns. Making the case for independence are Dr Stephen Watson and Professor Mike Lean, both from the University of Glasgow. Dr Patrick Harkness, also from the University of Glasgow, and Professor Hugh Pennington, emeritus professor at the University of Aberdeen, make the case for remaining in the union. Producer: Fiona Roberts.

Bardarbunga A group of earth scientists was in Iceland performing annual maintenance of its equipment, when the volcano Bardarbunga erupted. Professor Simon Redfern has now joined them and speaks to Adam Rutherford from the slopes of neighbouring volcano Askja. He explains how all this recent volcanic activity is the expression of Europe's tectonic drift away from America. And rather than this being a smooth, continuous process, the plates move at the surface in a jerky way - causing these earthquakes and volcanic eruptions.Geology in Minecraft The British Geological Survey has built a full version of the geology of Britain into the online game Minecraft. Minecraft is a so-called 'sandbox' game, meaning there are no specific objectives, but players are free to explore existing worlds or collaborate to build their own with a range of virtual building blocks. The game is a huge phenomenon, with over a 100 million registered users, mostly under the age of 30. By adding an extra layer of geological features, the BGS hopes to encourage interest and add a further dimension to the game.Synthesising opioids Opiates such as morphine are commonly used in pain-relief medicines, but their chemical complexity means that commercial production is limited and the pharmaceutical industry has to rely on extracting them from poppies. However, researchers at Stanford University are working on a synthetic-biology system using yeast to produce opiates like morphine, and the pharmacologically more attractive opioids like hydrocodone and oxycodone. They haven't got all the steps in the pathway in place yet. But they're not far off.Ammonia In recent years there's been renewed interest in ammonia, as a fuel. It could work as a replacement for petrol and diesel in cars with very little engine change. In fact it was used as such during the Second World War in Belgium.Producer: Fiona Roberts.

Manipulating mouse memory Optogenetics allows researchers to use light to turn the genes involved in memory, in the brain, off and on. It's a powerful tool for seeing exactly where specific types of memory are formed and processed. Researchers at MIT have been using the technique to manipulate fearful or pleasurable memories associated with a particular location, in mice. This is so they can see how memories are overwritten in the brain's processing regions. London pollution Cities in Britain have moved on a great deal from air pollution events, like the London smog of 1952, where 4000 people died in a week. But a recent report has put London air pollution levels as bad as some of the worst in the world, on a level with Mexico City and Beijing. Pollution is a mixture of gases and tiny particulate matter (or PM) -particles too small to be filtered out by our noses, and which end up going straight into our lungs. Dr Rossa Brugha and reporter Marnie Chesterton take a bicycle ride through London's busy streets and parks with an air pollution monitor. Back in the studio, Rossa and Adam talk through the results... Nature of knowing Philip Ball, the programme's on-call polymath and author of 'Invisible, the Dangerous Allure of the Unseen', comes into the studio to answer a listener's question about how science can possibly understand the unseeable, if it is supposed to be dealing with the observable universe. Snail fur and how to grow a new head Why is it that some animals can regrow lost body parts and others, like us, can't? Even some closely related species, for instance salamanders, can regrow a lost tail, but fellow amphibians, the frogs, can't regrow lost legs? One of the best-studied 're-generators' is the sea creature - Hydractinia, or Snail fur, because it grows like fur on the back of the snail-shell homes of hermit crabs. By studying Hydractinia's regenerative powers at the cellular level, researchers think that most animals, including us, may have the potential to regrow lost limbs using stem cell systems lying dormant within us. Producer: Fiona Roberts.

TB in the New World Brand new work in comparative genetics is shedding light on the spread of TB. Scientists have shown that the initial spread of the deadly bacterial disease tuberculosis to the Americas didn't come with the European explorers and invaders. Skeletons of pre-Columbian Peruvians have shown signs of TB. So where did it come from? DNA samples collected from the ancient bacteria show they're closely related to the TB strain that infects seals and sea lions. So did the disease pass from humans in Africa to seals on the coast which then crossed the ocean and infected the Peruvians, 1000 years ago? Truth, Trust and the internet A recent YouGov poll revealed that the British public trusts the online encyclopaedia Wikipedia more than it trusts the BBC. The internet has revolutionised how we receive information and check references. But how much should we trust online facts? Adam talks to Carl Miller, from the Centre for Analysis of Social Media at think-tank Demos, about how Wikipedia entries are created and regulated. And he asks him whether the democratisation of facts - created by crowd-sourced opinion rather than individual experts - is something we should welcome? Shipwreck of the London The London was a 64-gun second-rate ship of the line of the English Royal Navy, launched in June 1656 and commanded by Captain John Lawson. The ship was accidentally blown up in 1665 and sank in the Thames Estuary. The wreck was rediscovered in 2008, and is considered important partly for its historical references and partly for its insight into an important period in British naval history. English Heritage and Cotswold Archaeology are examining the remains in the murky Thames estuary before they decide what to do next. Although the wreck could be at risk from increasingly acidified water and invasive shipworm, it's thought unlikely that they will raise the ship, due to a lack of museum space. Lego Academics Campaigns for better female scientist role-models are not new. But what is new and welcome is when industry and society listens. Plastic toy brick manufacturer, Lego, has recently come up with a new set called the 'Research Institute' and it consists of lab kit and three female scientists - a palaeontologist, an astronomer and a chemist. Real life scientist and archaeologist Donna Yates, from the University of Glasgow, has gained thousands of Twitter followers after posting photographs reflecting the daily frustrations of academic life using the Lego figures. She arranges them in academic scenarios and posts her pics to the @LegoAcademics account. It's fun and full of in-jokes, but it gives great insight into some of the real issues scientists, and in particular, female scientists face. A Lego version of Adam Rutherford conducts the interview. Producer: Fiona Roberts.

Anaesthetics. General anaesthetic is an essential part of modern medicine. Millions of surgical procedures, many life-saving, simply could not be performed without rendering the patient unconscious with one of a long list of drugs that induce anaesthesia. But, we don't know how they work. Part of this mystery is because we're not entirely sure what we mean when we say unconscious. But part of it is that there's a whole fleet of different molecules than can work as an anaesthetic, so there's no well-known pathway we can study. Neuroscientist, Luca Turin at the Alexander Fleming Research Center in Greece thinks that the answer to how they work, could lie, not at the chemical level, but at the quantum level.2014 Iquique Earthquake in Chile Before the massive 8.1-8.2 Magnitude earthquake struck Iquique in Chile, in April, this year, there were a series foreshocks at the fault line. Adam Rutherford asks Roland Pease if these creaks could be a way of warning us about an imminent big quake in the future. They also discuss whether the stress released by the megathrust quake means the region will be seismically inactive for a while. The experts think not.Strange Weather We are obsessed with the weather. It is a powerful, shared daily experience, offering us an immediate talking point. Yet when we talk about climate change the sense of guilt or powerlessness can often be enough to kill the conversation. A new exhibition at Science Gallery at Trinity College Dublin aims to engage conversations about both weather and climate in a playful, provocative way. By bringing together works by artists, designers, scientists, meteorologists and engineers STRANGE WEATHER asks questions such as: Should human culture be reshaped to fit strange weather or should we reshape weather to fit our strange culture? Who is going to take advantage of climate chaos and how will strange weather benefit me? How will you choose to work, celebrate, live and die when weather gets weird?Strange Weather runs at Science Gallery, Trinity College Dublin from 18th July to 5th October 2014 Neutrinos A listener writes in to ask if we will ever run out of room in our Universe for the trillions and trillions of neutrinos being created. Malcolm Fairbairn at Kings College London does the maths.Jellyfish Last year was a record for jellyfish sightings off the UK coast. We know very little about our jellyfish, and experts at the Marine Conservation Society want to know more. They're set up a survey, complete with photographic guides and reporting forms for you to send in your sightings of these coastal visitors.Producer: Fiona Roberts.

Dinosaur A jumble of bones found in Venezuela belong to a group of very early dinosaurs, that could have been herd animals. Paul Barrett from the Natural History Museum explains to Professor Alice Roberts how a jumble of bones found in a 'bone bed' belong to a number of individual Laquintasaura venezuelae dinosaurs. They are an ancient, small, omnivorous dinosaur, which could have survived the Tertiary/Jurassic extinction event 200 million years ago.Genetically Editing Chickens Diseases devastate livestock around the world. In chickens for example the deadly strain of bird flu and the lesser known bacterial infection Campylobacter, does not only harm the chickens but is also a real threat to human health and welfare. Scientists are continually trying to develop vaccines, but the strains of bacteria keep evolving resistance to them. One of the solutions being explored at the Roslin Institute in Edinburgh, is genetic. Using a subtle form of genetic modification, called genome editing. The team are trying to find the genetic components of natural resistance in a wide group of chicken breeds, which they can then insert into the genome of livestock fowl in the hope of breeding healthier, safer chickens. Lightning A listener asks why lightning is jagged. Rhys Phillips from Airbus Group in Cardiff makes lightning in a lab. He has the answer.Rosetta The European Space Agency's robotic spacecraft Rosetta has reached the orbit of the comet Churyumov-Gerasimenko, and is about to start its detailed study. In the audacious and risky mission, the craft will follow the orbit of the comet as it approaches and passes the Sun. It will attempt to land a probe on the surface of the icy, rocky mass. It's hoped the mission will provide great insight into what comets are made of, how they behave as they heat up, creating its gassy coma and tail. And it's hoped Rosetta and its lander will be able to tell about where Earth's water and even some of the building blocks for life might have come from.Diatoms A type of phytoplankton, found in water, called Diatoms build hard silicon-based cell walls. Researchers, at the University of Galway, have shown it's possible to chemically transform the shells of living diatoms so they could carry drugs into our bodies in entirely new ways. Producer: Fiona Roberts.

ExpeRimental There's an online wealth of science demonstrations you can try at home with your kids. But what's sometimes lacking is the encouragement of questioning the science in these DIY experiments. Science teacher and film maker Alom Shaha has devised a series of videos with the Royal Institution showing parents experimenting with home-made lava lamps, bubbles and bottle cannons. He hopes that amidst the mess and mistakes, some scientific thinking can be nurtured.Rosetta The European Space Agency's robotic spacecraft Rosetta is about to start its detailed study of the comet Churyumov-Gerasimenko.

You can study a huge range of topics from cancer and dental photography to quantum physics, and even the archaeology and history of Hadrian's Wall. Critics say these higher education courses are just a PR exercise by universities, and that it will set up a two tier system in education. But Kathryn Skelton from FutureLearn, a platform for many of these MOOCs, argues that they encourage people who would not normally extend their education to take part and the universities providing the courses can gain great insight into the changing face of teaching methods.Evolutionary Psychology Last week Adam Rutherford and Alice Roberts had a robust discussion on the biologising of the human condition, with Professor David Canter. Listeners wrote in to complain that we didn't give an evolutionary psychologist a right to reply, so this week, listener and evolutionary psychologist Rob Burriss has his say.Producer: Fiona Roberts.

Face recognition The software that analyses images of your face, captured online or when you're out and about, has rapidly improved. Adam visits Amscreen, to test the cameras they deploy at supermarket checkouts to determine your age and sex, to inform advertisers of the best demographic to target. This raises ethical and privacy issues which Adam discusses with privacy expert Professor Colin Bennett and author of "The formula, about algorithms and the algorithm culture", Luke Dormehl.Quantifying expressions Is a look of contempt, or a smile, a universal expression or do they vary across cultures? Marnie Chesterton visits Glasgow University's Institute of Neuroscience and Psychology, where the scientists are building a huge database of faces, in order to unpick and quantify our expressions. Dr Oliver Garrod from the Generative Face Grammar Group demonstrates how they can capture your face, and animate it.Evolutionary psychology There is a long list of evolutionary explanations for the human condition. Mostly these are quite trivial. Teen boys develop acne on their faces to deter females from fertile but psychologically immature mates. Babies cry at night to prevent parents further procreating, resulting in potential sibling rivals. At the other end of the scale, these sorts of explanations have been used to suggest deeply problematic ideas, such as rape being an evolutionary strategy.Professor David Canter, a psychologist from University of Huddersfield has railed against this fashion for 'biologising' our behaviour. And evolutionary biologist Professor Alice Roberts is also critical of 'adaptionism' - the idea that everything has evolved for an optimal purpose.Producer: Fiona Roberts.

Plants and bees The relationship between flowering plants and bees is a long-evolved, complex one. Plant scientists at the Royal Botanic Gardens at Kew are currently conducting field trials to see how Acontium, or Monkshood, uses toxins to protect itself against nectar-thieving, short-tongued bumblebees. But how does it make sure it doesn't poison the helpful, pollinating long-tongued bumblebees? Plants from Roots to Riches Professor Kathy Willis, Director of Science at the Royal Botanic Gardens Kew will be presenting a new series on BBC Radio 4 exploring our relationship with plants from the birth of botany through to modern day. She describes some of the series highlights. The Azolla Event A tiny ancient fern-like pond weed could have been responsible for changing the fate of the planet. Some scientists think that Azolla could have played a significant role in reversing an increase in the greenhouse effect that occurred 55 million years ago. The researchers claim that massive patches of Azolla growing on the (then) freshwater surface of the Arctic Ocean consumed enough carbon dioxide from the atmosphere for the global greenhouse effect to decline, eventually causing the formation of ice sheets in Antarctica and the current "Icehouse period" which we are still in. Chomping caterpillars Plants can hear. Well, they can sense sound-vibrations. New research from the University of Missouri shows that when the mustard-like Arabidopsis senses the chomping sounds of a caterpillar munching on leaves, it primes itself for a chemical response. Composting low down A listener asks why orange peel takes so long to rot down in the compost heap? Is it because it's an exotic fruit? Adam asks Kew's Head of Horticulture and 'keeper of the heap' Dave Barns. Producer: Fiona Roberts.

Airport security has been tightened recently. Passengers must be able to switch on their electronic devices to prove they don't contain explosives. Inside Science asks about the science behind spotting a potential terrorist. Adam asks whether behavioural profiling works. Can trained security staff tell the difference between a nervous traveller and a potential terrorist?Light and colour in art Pigments and paint evolved over time, and these changes are one focus of the 'Making Colour' exhibition at the National Gallery. Different paints fade and degrade in different ways; often the patina of age is what appeals when looking at art, so how do you decide which hue to use when restoring paintings? Another intriguing issue is how you light a painting. The National Gallery is moving away from tungsten lighting, to more modern, tuneable LED lights. How does this affect the way visitors view the art? An interactive experiment is helping them to unpick light perception.Hadrian's Wall A listener asks how did the Romans knew where to build the great defensive wall. We get the answer from Professor Ian Haynes, an archaeologist at Newcastle University, who reveals that the Romans were obsessed with measuring.Cassini mission to Saturn Cassini-Huygens is an unmanned spacecraft sent to the planet Saturn. The NASA-ESA-ASI robotic spacecraft has been orbiting and studying the planet and its many natural satellites for 10 years. Adam talks to the mission's leader of the imaging science team, Carolyn Porco, about how successful it's been. And he offers her a blank cheque to choose her next mission.Producer: Fiona Roberts.

Informed consent Facebook has been under fire for running a controversial 'emotion manipulation' study on 689,003 Facebook users. The experiment, to find out whether emotions were contagious on the social network, involved minor changes to users' news feeds. It's contentious because the users were not informed that they were taking part in an experiment. Facebook says, check the terms and conditions, but Dr Chris Chambers at Cardiff University says that the ethical standards for science are higher, and should involve informed consent. Dan O'Connor, Head of Medical Humanities at the Wellcome Trust, gives a short history of consent in experimentation. El Nino According to the Met Office, the world is almost certain to be struck by the "El Nino" phenomenon this year, with the potential to induce "major climactic impacts" around the world. Roland Pease investigates this flip in the climate state of the Pacific basin, and asks the experts studying this phenomenon, whether it'll be a major event and how it might affect the climate. Gravitational Waves The announcement, earlier this year, that the BICEP 2 telescope at the South Pole had detected evidence that gravitational waves exist may have been premature. Gravitational waves are theoretical phenomena, based on observation of polarisation of ancient cosmic light. Finding them, adds to the evidence that the Universe is expanding. The data has now been made public, but the confidence in the numbers is being questioned. Cloud cover A listener asks about cloud cover and night time temperatures, and how air temperature and moisture content interact. Our expert Peter Sloss from the Met Office answers. Producer: Fiona Roberts.

Longitude Prize 2014 Winning Challenge Antibiotics resistance has been selected as the focus for the £10m prize. The World Health Organization (WHO) has warned of a "post-antibiotic era" where key drugs no longer work and people die from previously treatable infections. The next step in the challenge is to tackle this resistance, by developing a simple, cheap, quick test that allows you to tell whether an infection is bacterial or not. This will conserve the 50% of antibiotics that are currently given in situations where they have no effect.Solar Cells A popular form of photovoltaic, or solar, cells is made using a harmful and expensive chemical called cadmium chloride. Now a team has found a new, cheaper, safer way of making solar cells by replacing the toxic element in the process with a material found in bath salts, magnesium chloride, and these are just as efficient. Professor Ken Durose from Liverpool University explains how it could reduce the cost of solar energy.New Species How easy is it to find a new species for science? Whilst in the Bornean jungle, Dr Tim Cockerill discovered that it was relatively easy - one fell in his cup of tea! It was a tiny parasitic wasp. Another new species, of the same type of parasitic wasp, was recently discovered in a school playground in the UK. So new insects seem to be quite easy to find, but what about a new mammal or bird? Tim reveals that finding the creature is just the start of a lot of work needed to get his finding published and accepted.Fijian Fisherwomen More and more conservationists are turning to local knowledge to work out the best way to save ecosystems. A great illustration of this grass-roots approach is underway in Fiji. They use a traditional system where villages will close an area of fishing grounds for a few months for fish stocks to recover. Conservationists are now learning about this system, known as 'tambu', to see if it can be used on a longer-term basis to help give fish stocks, that have become seriously depleted in the last few decades, a chance to recover.Physics questions University College London cosmologist, Andrew Pontzen answers questions sent in by listeners about why, given the immense heat at the Big Bang, is there so much hydrogen in the universe, and not more of the larger atoms, which are forged under conditions of great heat? And are black holes responsible for the missing matter in the universe?Producer: Fiona Roberts.

Antarctic Invasion Antarctica is the most pristine place on Earth, having only been visited by humans in the last 200 years, and being tens of thousands of miles from the nearest land. But these days, around 40,000 tourists and hundreds of scientists visit the Antarctic every year, and with them come stowaways in the form of bugs, beetles and plants. As a result, the ice -free areas of the Antarctic are at severe risk of invasion. Is it too late to do anything about it?Longitude Prize: Water How can we ensure everyone can have access to safe and clean water? Water is becoming an increasingly scarce resource. 44 per cent of the world's population and 28 per cent of the world's agriculture are in regions where water is scarce. The challenge is to alleviate the growing pressure on the planet's fresh water by creating a cheap, environmentally sustainable desalination technology. London's Becton desalination plant is expensive to run, and so used for emergencies only. Marnie Chesterton meets some Danish chemists using membranes from nature which could help make salt water drinkable, without the energy requirement of current technology.Patents in science European Inventor Award winner Christofer Toumazou explains his invention - a USB microchip that reads a patient's DNA. He tells Adam Rutherford how the patent system has protected his ideas.Longitude Prize: Antibiotics Dame Sally Davies explains why, in an era of growing antibiotic resistance, it's important to have a cheap, easy-to-use test to identify bacteria. Muna Anjum from the Animal Health and Veterinary Laboratories Agency is working on identifying those resistance genes in certain bacteria. Paul Freemont's team at Imperial College is using synthetic biology to build a device that can detect specific bacteria - precisely the sort of work that might answer the Longitude Prize's challenge.Producer: Fiona Roberts.

The first ball kick of the opening ceremony of the 2014 World Cup is taken by a young paraplegic Brazilian, wearing a robotic exo-skeleton, controlled using his mind. Adam hears from Miguel Nicolelis, the neurophysiologist behind the high profile science stunt. Closer to home Sophie Morgan, paralysed for a decade, demonstrates her robot exo-skeleton, or REX, which allows her to walk and stand.This week, scientists at the University of Reading claim to have created a computer that has successfully duped humans into thinking it was a 13-year-old boy. This has been widely reported as the first computer to pass the Turing test, but is it? Is this a leap forward in artificial intelligence or a case of moving the goalposts. Anil Seth from the University of Sussex, gives us his opinion.Forget the Internet of things, welcome, the internet of vegetables. An EU-wide project has developed "cyborg plants" with in-built sensors. These allow the plant to "talk" to scientists, giving them updates on water and nitrogen levels. Koushik Maharatna from the University of Southampton explains the benefits of being able to talk to plants.We are surprisingly good at remembering songs we haven't heard for many years, but what is it about a song that makes it so memorable? Is there a perfect formula? Scientists hope that a new game will find out. A citizen science project plans to analyse thousands of results from the songs best remembered by the public. Adam Rutherford sings along and asks Dr Ashley Burgoyne, a computational musicologist from the University of Amsterdam, why some songs are more memorable than others.Producer: Fiona Hill.

Moving Mountains Removing the tops off mountains was common practice in the eastern United States to strip mine for coal. Critics have previously called for it to be banned because of the health risks. But in China, the same thing is now happening but on a much larger scale, all to create new land for people to live on. In a comment piece in this week's Nature journal, Chinese scientists call this unprecedented geo-engineering "folly", and liken the practice to "performing major surgery on Earth's crust". Dr Adam Rutherford talks to Dr Emily Bernhardt from Duke University in the US about the potential risks of the Chinese mountain moving. Alien Invader Species Inside Science bug man, Tim Cockerill, responds to headlines that alien killer snakes, capable of killing dogs, cats and even children, are on the loose in Britain. He goes to look for the supposedly terrifying reptiles, and finds out instead, about a colony of aesculapian snakes, whose biggest meal might be a rat. In search of more danger, he goes on to Sheerness in Kent, to hunt for the "alien" yellow-tailed scorpion. These arachnids don't prove much of a threat either, he discovers. As long as you keep your trousers tucked in your socks. Longitude Prize: Zero Carbon Flight If our use of air travel continues to rise at the current rate, by 2050, it'll make up 15 per cent of global warming from human activities. If the Longitude Prize topic chosen is flight, the challenge will be to design and build a zero or close-to-zero-carbon aeroplane that is capable of flying from London to Edinburgh, at comparable speed to today's aircraft. Marnie Chesterton speaks to physicist Helen Czerski and Professor Callum Thomas, from Manchester Metropolitan's Centre for Aviation, Transport and the Environment, about the possible options. Football Stickers "Got, Got, Got, Need!". With the football World Cup upon us, footy-mad kids barter to fill their world cup sticker books. Adam talks to mathematician Professor Yvan Velenik from the University of Geneva, about the myth that some stickers are rarer than others, and shares his statistical analysis about how many stickers you would need to buy, to fill the book. Producer: Fiona Hill.

Women of science London's Royal Society was buzzing last week as historians and scientists chewed over the lives of iconic women scientists. But at a time when far more women go into science, the percentage who make it to professor is still alarmingly low compared to men. Last week's Revealing Lives event by The Royal Society was also about learning lessons from history which are of benefit to women working in science today. Mapping the ocean floor We really do know less about the ocean floor on Earth than we do about the surface of Mars, Venus and the Moon. In the case of the Red Planet, the maps are about 250 times better. This gap in our home-planet knowledge has recently been highlighted by the search for the missing Malaysia airlines plane MH370. The suspected search area in a remote part of the Indian Ocean is so poorly mapped, it's not even clear how deep the deepest parts are. Ocean floor mapping can be done by ship board echo-sounders, bouncing sound waves off the sea floor. But this is very expensive. A new cheaper, quicker way is to use a satellite to measure fluctuations in the sea surface caused by gravitational perturbations caused by underwater topography. Longitude Challenge 2014 - Food security By 2050 there will be an estimated 9.1 billion people on the planet. In the face of limited resources and climate change, how can we feed the world with less? Michael Moseley thinks eating insects is a start whilst Marnie Chesterton checks out a field of self-fertilising crops. And the issue that it's not always the amount of food, but the right food is highlighted in a report from the Metropolitan Manila area of the Philippines where a portion of fries and a burger is cheaper than a kilo of carrots. Amplituhedron Particle physicists have discovered a mysterious jewel-like object that exists in higher dimensions in mathematical space. This multifaceted object, The Amplituhedron, greatly simplifies the complex calculations that explain what happens during particle collisions - the kind of collisions studied at particle accelerators, like the Large Hadron Collider. No one's entirely sure exactly what this object is, or how important it might turn out to be - there's some suggestion it may challenge the very notion that space-time is a fundamental property of our universe. Joel Werner caught up with the man who discovered this jewel, Nima Arkani-Hamed, at the Institute for Advanced Study in the United States to try and unravel exactly what this mysterious object is. Producer: Fiona Roberts.

Longitude Prize 2014 The Longitude Prize offers a £10 million prize pot to help find the solution to one of the greatest issues of our age. Votes from the British public will decide what that issue will be. This week, the six shortlisted challenges have been unveiled. They cover flight, food, antibiotics, paralysis, water and dementia. Alice Roberts talks to Adam about why we need an X-factor for science. Over the next month, Inside Science will profile each of these challenges and explain how you can cast your vote. Matter from Light In 12 months' time, researchers say they will be able to make matter from light. Three physicists were sitting in a tiny office at Imperial College London and while drinking coffee they found what they call a fairly simple way to prove a theory first suggested by scientists 80 years ago: to convert photons - i.e. particles of light - into electrons (particles of matter) and positrons (antimatter). Adam discusses the work with theoretical physicist Professor Steven Rose from Imperial College London and science writer Philip Ball. Longitude challenge - Dementia How can we help people with dementia to live independently for longer? Dr Kevin Fong is the champion for this Longitude Challenge, arguing that we all use technology to support our lifestyles but that people with dementia need extra tech. Marnie Chesterton visits Designability, a Bath-based design charity that works with people with dementia to develop new technologies. Their Day Clock shows that a simple design can produce radical results. Coastal deposition The destructive winter storms that hit the UK caused were flooded by the worst tidal surge on the east coast in 60 years. Sand dunes play an important defensive role on our coastline but little is known about their resilience or recovery rate. So after the December 5th storm, scientists sprang into action in Lincolnshire with a new project that officially began in February. The aim is to help future coastal management by researching the effects of storm surges on sand dunes. Producer: Fiona Roberts.

Melting Antarctic Ice Shelf Nothing can stop the collapse of the Antarctic Western Ice shelf. That’s according to NASA this week. Key glaciers in Antarctica are irreversibly retreating, and according to the scientists studying this region they’ve reached a state of irreversible retreat - the point of no return. Brain enhancing devices If given the option, would you think faster or increase your attention span? Neuroscientists now say that non-invasive brain stimulation using electrical currents could do just that. The technology is still fairly new but is now being sold by commercial companies often marketed to gamers suggesting that it could increase your attention and make you think faster. But do they actually work? Inside Science sent Melissa Hogenboom to Oxford try one out and to discuss the science behind the hype.Black holes How big can black holes get? A listener asks and Professor Andy Fabien, Director of the Institute of Astronomy at Cambridge University answers.Optical and atomic clocks At this week’s ‘Quantum Timing, Navigation and Sensing’ Showcase at the National Physical Laboratory, researchers are working on sensors that allow us to see through walls; super-accurate atomic clocks the size of matchboxes; and GPS trackers that can elude an enemy jamming the signal. We sent Inside Science reporter Tracey Logan to work on her time management.Bat jamming moth noises and other insects that go bump, chirrup, squeak in the night Inside Science’s resident entomologist, Dr. Tim Cockerill has been exploring a whole soundscape that’s hidden from our limited hearing range. Including, eavesdropping on a secret sonic arms race between echo-locating bats and bat-jamming acoustics created by the genitals of a hawkmoth.Producer: Fiona Roberts

Artificial DNA DNA is the molecule of life, conserved across all living species for 4 billion years. But now scientists have made a new, artificial version, by introducing two extra letters, not found in nature, into the genetic code of a common microbe. The E. coli bacteria are able to grow and replicate as normal despite these artificial additions. In future, this research might create organisms that can make new proteins, which could offer new drugs and vaccines. What is fire? A listener wrote in to ask about fire – what is it? And what is the difference between a super-hot gas and plasma? We went straight to Dr. Guillermo Rein, Mechanical Engineer at Imperial College and Editor-in-Chief of the journal Fire Technology. It turns out, they’re great questions and even the experts can’t quite agree on the answers. Obituary - Colin Pillinger British planetary scientist Professor Colin Pillinger, best known for his 2003 attempt to land a spacecraft on Mars, has died aged 70. . Oxford Maths Institute The new Maths Institute at Oxford University is named the Andrew Wiles Building, after the mathematician, who solved Fermat’s Last Theorem. The Institute includes some nods to other mathematical theories included in the design. From the never-ending Penrose paving at the entrance to lighting based on solving complex equations and mathematical illusions build into the construction. The architects hope the building will inspire the next generation of mathematicians. Carlos Frenk Professor Carlos Frenk, astronomer at Durham University has just joined the ranks of Steven Hawking, Edwin Hubble and Albert Einstein by winning the Royal Astronomical Society’s Gold Medal for Astronomy.

A recent paper demonstrated that mice show elevated stress levels in the presence of male hormones. What implications does this have for future mouse research? Adam Rutherford heads to University College London to speak to Dr Clare Stanford, who works with mice and men.How do you get jet fuel from thin air? Just add water, carbon dioxide and a large amount of concentrated sunlight. A team from the European Solar Jet Project has, for the first time, proved that you can make 'green' or carbon neutral paraffin, the hydrocarbon used in jet fuel. It's feasible; the next step is to try and make this process commercially viable.Neuroscience is a fast growing and popular field, so naturally there are an abundance of stories reported in the press often illustrated with a beautiful picture of the brain. But despite the advances, when an area of the brain 'lights up" it does not tell us as much as we'd like about the inner workings of the mind. Adam Rutherford speaks to neuroscientists to get to the bottom of what brain imaging can be useful for and when over-interpretation is an issue.Our resident zoologist Dr Tim Cockerill recently found himself filming animals deep in the jungles of Borneo. Before he left, we gave him an audio recorder to see what he could discover about the animal communities there, just by listening to them. It seems you can set your watch by some of their calls.Producer: Marnie Chesterton.

Y Chromosome We learn from a young age that if a fertilised egg carries XX chromosomes it will be a girl, but with XY it will be a boy. This male Y sex chromosome has lost many genes along its evolution over the past 180 million years and now only about 20 genes remain. Now two new studies in Nature journal have given clues into how the Y chromosome evolved into its current state by looking at the genetic make up of 15 species the team built an archaeological record of all the mutations that occurred over time - to trace the timing of how the Y originated.... Professor Henrik Kaessmann from the University of Lausanne in Switzerland explains that the genes that remain play a more important role than previously believed.Everest Avalanche Last week the biggest single loss-of-life event occurred on Everest: a huge avalanche killed 16 Sherpa guides. All were so-called "icefall doctors", possibly the riskiest job of all, which involves finding a route through the broken mass of icefall, and then securing ladders and ropes for mountaineer tourists to follow. The Himalayan Sherpas have abandoned the climbing season out of respect for the fallen. There are many questions about health and safety, but we want to know what could be done to help? BBC Science Reporter Victoria Gill has been looking at the science behind avalanches, Are avalanches predictable? And will global warming in the Himalayan region make them more common? Aphid Survey This month the Rothamsted Research in Hertfordshire's Insect Survey will have been monitoring national aphid populations for fifty years. Aphids, such as greenfly and blackfly, can cause extensive damage to plants and crops. The aphid season - as many gardeners will know - is just about to start. But how has the recent mild, wet winter affected their numbers?Lichens An Inside Science listener emailed in to ask about lichens - what are they and how do they live. We called in plant ecologist Professor Howard Griffiths, at the University of Cambridge to fill us in on these hardy, pioneering organisms.Longitude 300 years ago there was no way of knowing the position of a ship out on the high seas. The greatest scientific challenge of the age was navigation. Britain's response was to offer a large prize fund for the solution to the problem of Longitude. Richard Dunn, curator and head of science and technology at Royal Museums Greenwich tells Marnie Chesterton the story of John Harrison, a clockmaker and carpenter, who solved this seemingly impossible problem.Producer: Fiona Roberts.

How sperm recognises the egg The discovery of a protein on mammalian sperm almost a decade ago, sparked the search for the corresponding receptor on the egg. Now researchers in the UK have found this receptor in mouse egg cells. They propose to call it Juno, after the Roman Goddess of fertility and marriage. The finding indicates that these two proteins need to interact for normal fertilisation to occur. And in humans, it could lead to early screening of couple to decide which appropriate fertility treatment they require.Dogs as clinical models Dogs play an important companion role in society, but man's best friend can suffer from hundreds of different diseases. Surprisingly, many of these are very similar to human diseases, including cancer and autoimmune conditions. Research into a range of naturally occurring canine conditions has the potential to lead to some ground-breaking medical advances and improve human health.Automatic Facebook Keeping up with your online social network of 'friends' on Facebook can sometimes be time consuming and arduous. Now artificial intelligence expert, Boris Galitsky, has invented a robot to do the bulk of his social interactions online. But how realistic is it? And does it fool his cyber pals?Artistic brains feedback Last week we ran an item showing that researchers have found that artists' brains were structurally different from those of non-artists. This sparked a lot of listener feedback and debate on what is the difference between being an artist and being creative? Is it nature or nurture, or both? We attempt to get your points across!Invasive Alien Species The European Parliament has approved new legislation which hopes to contain the spread of invasive species of plants and animals in Europe. It has proposed bans on the possession, transport, selling or growing of restricted species. The list, which includes plants like Japanese knotweed and Himalayan balsam and animals like the "killer" shrimp, which can wreak havoc when they spread, was restricted to just 50 species. But now it will be open-ended, so when new alien invasive species arise, they can be dealt with more easily. But in the UK, what constitutes an 'alien' species and how do you decide whether it's invasive? And what about all the 'alien' plants we already grow in our gardens?Producer: Fiona Roberts.

Whaling The International Court of Justice in the Hague recently ruled that Japan should stop whaling in the Antarctic “for scientific purposes.” They found that the primary purpose of the science programme, JARPAII, was not science. In that case, what was it for? Inside Science puts that question to whale biologist Vassili Papastavrou, and Lars Walløe, Japan’s expert witness at the ICJ.LUX Experiment to detect dark matter Scientists are entering a critical phase in the quest to find the one of most mysterious particles in the Universe. An experiment called LUX, in South Dakota is about to be switched on that offers the best hope yet of detecting dark matter - a substance thought to make up a quarter of the Universe, yet one that nobody has ever seen. Falling in the elderly As we age, we tend to fall more and the repercussions of falling are more serious But why? Even if you rule out physical reasons for why you might be more likely to fall, older people still fall more often. Professor Raymond Reynolds, at the University of Birmingham, thinks it might be something happening in their heads – the balance system could be letting them down. Tracey Logan climbs aboard the shake shack to find out.Arty Brains Artists often have lifestyle that requires complete immersion into their world, now a team finds that this difference is reflected in their brains too, that is, their brains are structurally different to non-artists. Participants' brain scans revealed that artists had increased grey matter in areas relating to fine motor movements and visual imagery. Our reporter Melissa Hogenboom speaks to artists and the authors of the new research to find out what exactly is different about their brains. The study is published in NeuroImage.

Calorie restriction Careful restriction of the number of calories eaten, without causing malnutrition, extends the lifespan of numerous organisms – from worms to mice – but whether it works in monkeys is controversial. Building on results from a long-running primate experiment, a team at the University of Wisconsin show a reduction in mortality, in response to caloric restriction. So there seem to be some benefits, but Tracey Logan asks if this can be applied to humans? And would we want to live longer on a tightly controlled diet?Dating the Moon New work by planetary scientists from France, Germany and the USA, has given the most accurate date yet for the birth of the moon. The Moon is believed to have formed out of debris from a massive collision with another Mars-sized planet. The date of this event has always been controversial as radioactive decay readings have produced wildly different results. But this clock uses a different approach, and rules out an early-forming moon. The later the moon formed, the less time for life to evolve.Mars Yard In 2016 Europe launches a mission to mars. ESA’s robotic rover will land on Mars in 2019, and in the meantime, needs to practice. To test it, scientists have recreated the surface of Mars, with 300 tonnes of sand. Reporter Sue Nelson went to Stevenage to play in the sandpit, for science.IPCC This week sees the most recent report from The Intergovernmental Panel on Climate Change, the IPCC. And the message is the same: the climate is changing as we continue to add greenhouse gases to the atmosphere. Should we concentrate on adapting to climate change, rather than stopping it? Professor of Coastal Engineering at Southampton University, Robert Nicholls and Dr Rachel Warren of the UEA’s Tyndall Centre for Climate Change Research discuss adaptation plans.Producer: Fiona Roberts

School Report on Fracking This week, Inside Science is taken over by BBC School Reporters and Melissa Hogenboom eavesdrops on a school in Lancashire, preparing their report on fracking. They discuss the issues very local to them, as well as the wider international angles and how best to present the story. Purple GM tomatoes The chemical that gives blackberries, blackcurrants, blueberries and some red grape varieties their distinctive purple colour is Anthocyanin. It’s been shown to have some possible anti-cancer properties as well as some protection against cardiovascular disease. So scientists at the John Innes Centre have inserted the ‘purple gene’ into tomatoes to try and boost their health-giving properties. This step is relatively easy, compared to navigating the rules and regulations of getting to the stage of producing purple ketchup. Gareth Mitchell asks the School reporters what they think about Genetic Modification of food crops. Artificial humans With progress in 3D printing of organs, brain-machine interfaces and even artificial skin. Materials scientist at University College London, Professor Mark Miodownik, thinks that the future really could be bionic. Would the School Reporters want to become half human, half machine? And would these technological advances just be used for repairing people who have been injured or really need it, or will it mean that those with enough money could enhance themselves to superhuman states? Shark Attacks Potentially dangerous sharks are being culled off the coast of Western Australia. The government claim it’s as a result of a rise in the number of deaths by shark attack. Many people are outraged by the killings. Shark attacks are still really rare compared to car accidents or even deaths from bee stings – so do the School Reporters think this is a good idea? Or do they think listening to what the scientists studying shark behaviour and developing shark deterrents say, is a better way to go?

Cosmic Inflation and Gravity waves Scientists in the BICEP 2 Group say they've found the earliest rumbles of the Big Bang. Theory predicts how the universe first expanded. Now we have the first observation of the phenomenon behind it. The universe was kick-started by a so called 'inflation' - vigorous growth within a fraction of a second of the Big Bang going bang. To confirm inflation you need to detect ripples in the fabric of space called gravitational waves. And to find those, you need to look for twists and kinks in this stuff. The BICEP 2 radio telescope, at the South Pole, has been measuring the direction of twists of light from the Cosmic Microwave Background Radiation - which is a form of primordial light, a remnant of the Big Bang. The signals have been released that show distortions in that light that can only have been caused by gravitational waves. They could only be there if there was inflation. In other words, these observations have shored up one of the most important theories in cosmology. Gareth Mitchell discusses what this means with BBC Science Correspondent Jonathan Amos and Astronomer at UCL Dr. Hiranya Peiris. Photonic Radar As the search closes in on missing Malaysia Airlines flight MH 370, radar technology has been in the spotlight. At the same time, new research published in this week's Nature journal reports on field trials of the next generation of radars - photonics based. Lead-author Paolo Ghelfi, from the National Laboratory of Photonics networks in Pisa, Italy explains their methods. Professor David Stupples, a radar expert from City University, London, explain that this cheaper, more accurate technology could end up in your car. Show Us Your Instrument - Infrared camera Infrared cameras detect heat, and process this as a colourful image. Dominic McCafferty, from Glasgow University, uses this kit to study stress levels in birds. When an animal is stressed, blood is drawn away from its skin and routed to the essential organs. This 'fight or flight' reflex means the temperature of certain parts of the animal drops. The infrared camera measures this, providing a non-invasive way of testing an animal's stress level. Current projects include one to test chickens, aiming to improve their welfare. Water research When listener Dave Conway emailed in to ask about what research is being done on water, if any - we went straight to materials scientist Professor Mark Miodownik at UCL to find out. Taxidermy Is taxidermy a dying art? Not for the chattering classes of New York apparently. There's been a rise in demand for people to attend classes where they learn to stuff and mount animals, and often dress them up in costumes. But what is the value of the stuffed animals in museums? In the multimedia age of interactive displays, 3D printing and computer models - do we still need the stuffed and stitched creatures in glass cases? Producer: Fiona Roberts.

Are black boxes outdated technology? With GPS widely available in everyday gadgets like mobile phones, how could Malaysia Airlines Flight MH370 just disappear? Adam Rutherford speaks to Dr Matt Greaves, a Lecturer in Accident Investigation at Cranfield University, about how we track aircraft.Earlier this year, a new study from Japan announced a curiously easy way to make stem cells, by placing them in a mild acid bath. It seemed too good to be true, and according to recent critics, it is. One of the authors has declared that the paper should be withdrawn, that he has 'lost faith in it'.Ivan Oransky runs the site RetractionWatch, dedicated to scrutinizing irregular research. He talks to Adam about the value of post-publication peer review, and public scrutiny of science on the internet.A 30,000 year old killer, buried 100 feet under the Siberian permafrost, has risen from the dead. It's a mega virus, with the largest genome of any known virus, and, happily, only infects amoebae. Virologist Professor Jonathan Ball, of the University of Nottingham, explains the implications of reanimating dead viruses.And actual spaceman, retired NASA pilot Captain Jon McBride, came into the studio to share his out-of-this-world memories and prediction that the next generation of astronauts will be chosen on brains not brawn.Producer: Fiona Roberts.

Chemical weapons Disposing of Syria's chemical weapons is a difficult task, both politically and technically. The Organisation for the Prohibition of Chemical Weapons (OPCW), responsible for the decommissioning, has kitted out a special ship, the MV Cape Ray to hydrolyse "priority" toxic substances. Hamish de Bretton Gordon, a chemical weapons expert from SecureBio, explains why destroying chemical precursors on dry land is not an option and whether the job will be done on time. Tracking turtles Satellite tags have finally given researchers insight into the "lost years" of loggerhead turtles. After many failed attempts, researchers have worked out how to attach the tiny tags to the months-old animals during the uncertain period when they leave US coastal waters and head out into the Atlantic Ocean. The data suggests the loggerheads can spend some time living in amongst floating mats of Sargassum seaweed, in the Sargasso Sea. Technology for Nature The tools and gadgets available to remotely track animals and monitor populations and their habitats are getting better and more mechanised. Cameras mounted on birds can record where they fly; audio recordings capture bat calls; satellite images monitoring habitat change. However all this digital data needs to be analysed. Professor Kate Jones, an expert on biodiversity at University College London, thinks that this is where more technological advances are needed. She wants image recognition programmes to scan through millions of remote camera images, or sound recognition of hundreds of thousands of bat calls to be developed. Climate The recent extreme rainfall has left many asking, is this weather linked to climate change? A new project 'weather@home' 2014, aims to use a large citizen science experiment to answer this question. Myles Allen, Professor of Geosystems Science at the School of Geography and the Environment, and Dr Nathalie Schaller, both of Oxford University, explain that they aim to run two sets of weather simulations. One will represent conditions and "possible weather" in the winter 2014, and the second will represent the weather in a "world that might have been" if human behaviour had not changed the composition of the atmosphere through greenhouse gas emissions. By comparing the numbers of extreme rainfall events in the two ensembles, 'Weather@Home' will work out if the risk of a wet winter has increased, decreased or been unaffected by human influence on climate. Producer: Fiona Roberts.

Neuroscientist Miguel Nicolelis is one of the world's leading researchers into using the mind to control machines. He is involved in the "Walk Again Project" which aims to build a suit that a paraplegic person can wear and control so that he or she can kick a football at the opening ceremony of the 2014 World Cup in Brazil. Adam is joined by biomedical engineer, Professor Christopher James from Warwick University, who puts the field of Brain Machine Interfaces in context. Work published last week by Professor Ziv Williams looks at the possibility of rewiring the body. Paralysis is normally confined to spinal cord damage, not the limbs themselves. Ziv Williams' work aims to use implanted chips to bypass the injury and have the individual control their own paralysed arms. Listeners ask if there is a gene for fundamentalist intolerance. We put the question to Professor Tim Spector, author of Identically Different. Adam Rutherford heads down to the psychology department at London's South Bank University... for a pint. Dr Tony Moss has built a fake pub, complete with lighting, music and even a fruit machine, to make drinkers feel that they are in a real bar. He says the venue treads a middle ground between a sterile lab, and an actual pub, where there are too many variables to reliably study behaviour. Professor John Shepherd from Cardiff studies alcohol and behaviour from the other end - the drunken nights out that end up in A&E. A few simple initiatives have helped reduce violence levels by 40% Producer: Fiona Roberts.

Bees - Nearly all bees in the UK suffering serious declines. They're mostly threatened by habitat and land-use change. But disease also plays a part. Adam Rutherford talks to Professor Mark Brown about new work he's done looking at the evidence of diseases harboured by honeybees, spilling over into wild bumblebees. Pain and epigenetics - Marnie Chesterton goes to Kings College, London to watch identical twins being tested for pain tolerance. The study is to gain insight into the genetic components of pain perception. One area which is fascinating researchers like Professor Tim Spector is the role of epigenetics in how we process pain. Our epigenome is a system that changes the way our DNA is interpreted. Genes can be dialled up or down, like a dimmer switch, by adding little chemical tags to the DNA. These chemical tags, unlike DNA, are changeable, in response to the changing environment. So could the way we live affect the pain we feel? Whales from Space - More listeners' questions, this time, asking whether surveys using images from satellites to see whales underwater, could be hijacked by whale hunters? Peter Fretwell from the British Antarctic Survey has the answer. Genetics of sexual preference - The media is all of a twitter this week over unpublished work recently revealed on research looking for genes related to homosexuality. We hear from Professor Tim Spector on the topic, and Adam talks to Professor Steve Jones about the science. Producer: Fiona Roberts.

Whales from Space. Scientists have demonstrated how new satellite technology can be used to count whales, and ultimately estimate their population size. Using Very High Resolution (VHR) satellite imagery, alongside image processing software, they were able to automatically detect and count whales breeding in part of the Golfo Nuevo, Peninsula Valdes in Argentina. The new method could revolutionise how whale population size is estimated. Marine mammals are extremely difficult to count on a large scale and traditional methods are costly, inaccurate and dangerous; several whales researchers have died in light aircraft accidents. How long will the floods last? Is this a trend caused by climate change? Should I turn on the kitchen taps so that house is at least flooded with clean water? We put listeners' flood questions to experts from the Centre of Ecology and Hydrology and the British Geological Survey. The instrument we're shown this week is from JET (Joint European Torus) in Culham,. It's the world's largest 'tokamak' - a type of nuclear fusion reactor. The hope is that in a few decades it could be supplying much of the world's electricity. It works by fusing nuclei of hydrogen together to produce helium and a lot of excess energy. It's the power source of the Universe, as all stars run on fusion energy. But on Earth we have to go to much more extreme conditions to achieve it. Upwards of 100 million degrees Celsius, which is around ten times hotter than the Sun. Joanne Flannagan, shows us her lasers which measure the hot fusion plasma inside JET. CERN wants a new tunnel. The 27km long, Large Hadron Collider in Geneva found evidence of the Higgs boson recently. But if we want to know more about this elusive particle and others that make up our universe, the physicists say they're going to have to go bigger. With a 100km long tunnel, in fact. Talks are afoot as to where and how they will build it. But Lucie asks reporter Roland Pease whether it'll be worth it? The current Discoveries exhibition at Two Temple Place, on the banks of the Thames, brings together treasures from eight University of Cambridge museums, in a beautiful period building, built by Waldorf Astor. The show combines objects from science and arts collections to explore the theme of 'Discoveries'. Curator Professor Nick Thomas gives Lucie Green a tour. Producer: Fiona Roberts.

The warning that floods are likely to become more common, or more severe, won't be a high priority for those with homes currently deluged. But it is something architects, engineers and planners have been taking very seriously. Dr. Adam Rutherford finds out about some of the innovations, both in UK and abroad, being designed for homes in areas prone to flooding - from simple door guards and waterproofing which can be retrofitted to existing houses - to entire city re-landscaping, or 'waterscaping' which aims to make room for the river, rather than fighting against it. Last week Adam talked about research showing that most people of European or East Asian descent carry a small percentage of Neanderthal DNA - about 2%. He examined some of the physical characteristics we may have got from the genes of our ancient cousins. This week Inside Science addresses some of the questions this fascinating work prompted. A new study in the journal Neuron this week, looks at what happens in the brain when one of the senses is dulled. Dr. Patrick Kanold, from the University of Maryland in the States, and his colleagues simulated blindness in mice by keeping them in the dark for a week, to see what happened to the parts of their brains involved in hearing. The found that the mouse's hearing improved. We sometimes talk about the brain being 'hardwired': all the neurons locked in place from early childhood. It was assumed that there was only a short, finite period when the brain was still capable of changing, but the new research shows parts of the brain still has room to manoeuvre. A recurring problem in science is that we are far better at collecting vast amounts of scientific data than we are at actually analysing them. To combat this problem, the charity Cancer Research UK have just launched a mobile phone game, 'Genes In Space', that farms statistical analysis out to the masses. Under the guise of flying a spaceship through a meteor storm, game players actually navigate their way through genetic sequence data from breast cancer patients. The information on the virtual path they take is automatically uploaded to the database and fed back into the scientific process. Producer: Fiona Roberts.

We now know that Neanderthals and our ancestors interbred over 40,000 years ago. Recent research has shown that most people of European or East Asian descent carry a small percentage of Neanderthal DNA - about 2%. But two new papers this week examine some of the physical characteristics we may have got from the genes of our ancient cousins. They include some disease susceptibilities and hair and skin characteristics, which may have helped our forebears survive in northern climes.There have been many sensationalist headlines in the news this week suggesting that the deadly bubonic plague could return, when really, it never went away. And while it can still be deadly, it can be treated early with antibiotics. In the Middle Ages the Black Death is thought to have killed up to half of the European population and so too did the Justinian Plague 800 years earlier. Now scientists have compared these two plague genomes to find that they were both caused by distinct strains of the same bacterium, Yersinia Pestis. Knowing how the pathogen evolved in the past is crucial to our understanding of possible future strains of plague. Lead author Dr David Wagner from the University of Arizona tells Dr Adam Rutherford that it's very unlikely the plague will return on a mass scale.It's a windy Show Us Your Instrument this week - Prof Konstantinos ('Kostas') Kontis, Professor of Aerospace Engineering shows us around his wind tunnel. It's used to help develop more effective plane wings, helicopter rotors, and wind turbine blades, but cyclist Sir Chris Hoy has also been a test sample. Glasgow University is currently building a hypersonic wind tunnel, which can test air flow at speeds of up to Mach 10.We all unconsciously synchronise our movements and researchers at the University of Birmingham have shown how professional musicians make tiny adjustments in their playing to keep time with their colleagues. Alan Wing, Professor of Human Movement in Psychology tells Adam how this research about minute synchronisation is helping to inform how robots can be designed to interact with humans.Stem cells can become any other cell in the body from nerve to bone to skin, and they are touted as the future of medicine. Embryos are one, often ethically charged, source of stem cells and in 2006 Nobel prize winning research showed that skin cells could be "genetically reprogrammed" to become stem cells. These were called induced pluripotent stem cells. Scientists in Japan have now shown, in mice, that this previous painstaking method of making the versatile cells can be replaced by little more than a short dip in acid. Professor Chris Mason from University College London tells Adam that this major breakthrough could be faster, cheaper and possibly safer than other cell reprogramming technologies.Producer: Fiona Hill.

The Higgs boson has been discovered, providing the final piece of the jigsaw puzzle for the Standard Model of particle physics, a description of how the universe works. But what physicists haven't found yet, which they should have, are supersymmetry or SUSY particles. Roland Pease attended a recent meeting of top physicists, and shares with Adam Rutherford the latest discussions about where to look next. The history of neutrinos is littered with interesting characters. It was Wolfgang Pauli who first suggested their existence. Pauli was so unsettled by his proposal that he bet a case of champagne against anyone being able to discover these "pathologically shy" particles. Since then, scientists have built ever more elaborate experiments to try and detect these particles. Ray Jayawardhana, Professor of Astrophysics and author of a new book "The Neutrino Hunters" explains more about the most abundant particle in the universe. This week's Show Us Your Instrument is a tool used to help scientists measure the glaciers in the Antarctic. Julian Dowdeswell, a glaciologist from the University of Cambridge, uses an echo-locator to look at the dynamics of large ice masses and their response to climate change. Fungi, not viewed favourably by gardeners, can be good for rainforest biodiversity. Dr Owen Lewis from Oxford University tells Melissa Hogenboom that plots sprayed with fungicide soon become dominated by a few species at the expense of many others, leading to a marked drop in diversity. A mysterious illness killing dogs has been in the headlines this week. David Walker a veterinary specialist, says that although it's not clear what's causing the disease, people should not panic.

For a couple of hundred quid, one of many companies will send you a kit for sampling your own genome, and most will tell you your genetic risk for some diseases. In December the US Food and Drug Administration imposed a ban on one of these companies, 23andme. The reasoning was that if the organisation is offering medical advice, it needs to be medically regulated. Geneticist Professor Robert Green from Harvard Medical School argues that people can cope responsibly with their genetic information and that the FDA is being over-cautious.Most people are familiar with recurrent infections caused by bacteria such as tonsillitis and bladder infections, where you pick up an infection, get treated with antibiotics and then after a few weeks or months the infection reappears and you need another course of antibiotics; this is a problem that can go on for many years, and is a major healthcare burden world-wide. Marnie Chesterton met a team from Imperial College studying the elusive persister cells responsible for these relapses.Earthquakes usually occur in subduction zones, where one tectonic plate plunges beneath another. Now a team at University of Aberdeen has analysed a large earthquake database and developed a global map giving clues to which areas could be capable of causing giant earthquakes. Professor Nicholas Rawlinson explains the difficulties of predicting.The venom of scorpions contains neurotoxins, which attack the nervous system of animals - it's one of the reasons why it's not a good idea to be stung by a scorpion. The structure of these toxins very closely resembles the structure of a group of proteins with a completely different purpose, called defensins. Professor Jan Tytgat from KU Leauven suggests that venom evolved from these defensins.

Scientists following in the footsteps of Edwardian explorer, Douglas Mawson, have been trapped in pack ice in the Antarctic. The Chinese vessel that came to their rescue also became "beset" in the ice. The BBC's Andrew Luck Baker talks to Adam Rutherford about the catacylsmic event that caused multi-year ice to break away and trap the Academik Shokalskiy and Professor John Turner of the British Antarctic Survey underlines the importance of differentiating between extreme weather events and the impact of climate change. A team at Rothamsted Research in Hertfordshire has succeeded in genetically engineering plant seeds to contain the Omega-3 oil usually found in oily fish. Seeds from Camelina sativa (false flax) plants were modified using genes from microalgae - the primary organisms that produce these beneficial fatty acids.The oil has now been incorporated into salmon feed to assess whether it's a viable alternative to wild fish oil. Dr Johnathan Napier tells Melissa Hogenboom that he hopes the plants will provide a sustainable source of long chain polyunsaturated fatty acids. From fossils we know an awful lot about the animals that walked on the Earth, swam in the sea and flew in the air. But fossils have never been good at revealing the colour of these animals. With increasingly sophisticated sampling techniques however, scientists are starting to get a much better, technicolour glimpse into these extinct fauna. And it turns out that colour played a much more important role than just camouflage and decoration. Johan Lindgren form Lund University in Sweden has been finding out how the pigment, melanin, allowed ancient marine reptiles to travel all over the oceanic globe. Show Us Your Instrument: Dr Andrew Polaszek, Head of Terrestrial Invertebrates at the Natural History Museum reveals his compound microscope (with Nomarski Differential Interference Contrast) which he uses to discover "hidden biodiversity", particularly in parasitoid wasps. Stephen Hawking threw a party for time travellers and issued the invitation after the event. Astrophysicists after a long poker game decided to use Twitter instead, to flush out the time travellers in our midst. Professor Robert Nemiroff from Michigan Tech University and his students mined social media for references to the Comet ISON and the naming of the new Pope Francis, before both those events had actually happened. Producer: Fiona Hill.

The ancient inhabitants of Britain; when did they get here? Who were they? And how do we know? Alice Roberts meets some of the AHOB team, who have been literally digging for answers.The Natural History Museum's Chris Stringer, is the Director of AHOB, the Ancient Human Occupation of Britain, a project which, over the past 12 years, has brought together a large team of palaeontologists, archaeologists, geologists and geographers, to pool their expertise in order to unpick British History.Nick Ashton from the British Museum has been in charge of the north Norfolk site of Happisburgh, where the crumbling coast line has revealed the oldest examples of human life in Britain, 400,000 years earlier than previous findings of human habitation, in Boxgrove in Sussex.The ancient landscape had its share of exotic animals. Hippos have been dug up from Trafalgar Square, mammoths have been excavated from Fleet Street. Professor Danielle Schreve is an expert in ancient mammal fossils, and tells us what these bones reveal about the ancient climate. Less glamorous than the big fossils, the humble vole is so useful and accurate as a dating tool that it has been nicknamed "the Vole Clock."Carbon dating has improved vastly in the past few years. Rob Dinnis, from Edinburgh University, explains why the AHOB team has been returning to old collections and redating them.

Professor Alice Roberts talks bacteriophages: viruses that infect the bacteria that infect us. With the rise of antibiotic resistance they are a potential weapon against infection.We hear from Paul Hebert, the biologist behind the International Barcode of Life project – a global effort to classify the entire world’s species according to their DNA. Bristol researchers have discovered that it is more than scent and colour that draws a bee to a flower – there is also an electric field.Claire Turner from the Open University shows us the instrument she uses to detect disease. It can sense when a heart transplant patient is rejecting their new organ, purely through monitoring their breath.

Antibacterial soaps and body washes make up an industry worth millions of pounds, but in the USA, producers have been told that they have just over a year to prove their products are safe, or, re-label or reformulate them. Many believe that using antimicrobial soaps, which often include the chemicals triclosan or triclocarban, keeps you clean and reduces the chance of getting ill or passing on germs to others. But the Food and Drug Administration in the USA says it's the job of manufacturers to demonstrate the benefits, to balance any potential risks. Professor Jodi Lindsay, expert in microbial pathogenesis from St Georges, University of London, tells Dr Adam Rutherford where this leaves British and European consumers. The world's most powerful satellite camera was launched today into space. Its mission, to map the billion stars in our galaxy. Professor Gerry Gilmore, Principal Investigator for GAIA, tells Inside Science about the planned "walk through the Milky Way" and BBC Science Correspondent, Jonathan Amos, spells out how GAIA could help detect future asteroids, like the one that wiped out the dinosaurs on earth. Just after the Second World War in a site in North Yorkshire, the discovery of a flint blade triggered the discovery of one of the world's most important Mesolithic or Stone Age sites. What makes Star Carr so special is that organic artefacts, bone harpoons, deer headdresses and even homesteads, were preserved in the peat 11000 years ago. But these precious artefacts are in trouble. Changing acidic conditions are turning the Mesolithic remains to jelly. Sue Nelson reports from the Vale of Pickering on how archaeologists are working with chemists to try to pinpoint exactly why the Stone Age remains are deteriorating so quickly. And Professor Chris Turney talks to Adam from his research ship in Commonwealth Bay in the Antarctic, where he is leading a team of scientists to recreate the journey made by Douglas Mawson, 100 years ago, on the Australasian Antarctic Expedition.

Food crime is now big business that criss crosses national boundaries, according to today's report into the safety and authenticity of our food. Public Analyst, Dr Duncan Campbell tells Dr Adam Rutherford that he and his colleagues are hampered by lack of funding and the lack of a national plan for a sustainable laboratory infrastructure. While report author, Professor Chris Elliott, the director of the Global Institute for Food Security at Queen's University, Belfast describes how he wants the UK's scientific infrastructure to be strengthened to avoid yet another serious food scandal.Show Us Your Instrument: Cosmic Scientist Dr Natalie Starkey from the School of Planetary and Space Sciences at the Open University reveals the NanoSims instrument.Thousands of miles apart the same species of microbes seem to crop up deep beneath the earth's surface in cracks of hard rock. Yet nobody seems to quite know how they spread so widely. Scientists now believe they may have survived completely isolated from the surface for what could be billions of years. Dr Matt Shrenk from Michigan State University explains that the biosphere as we know it is far more extensive than we previously thought.Crystallography... as it sounds is the study of crystals, but it's not quite as simple as that. It underpins many scientific fields and yet it remains a relatively unknown subject area. Scores of Nobel prizes have been won, the first almost 100 years ago and we wouldn't understand the structure of DNA without it. The United Nations has declared 2014 as the International Year of Crystallography and emeritus Professor Mike Glazer from Oxford University says he hopes it will help bring the subject out of the shadows.Producer: Fiona Hill.

Badger culls in England have ended and Professor Roland Kao from the University of Glasgow discusses with Dr Adam Rutherford the scientific options remaining to tackle the spread of bovine tuberculosis. Field trials of the TB cattle vaccine are due to start next year and Professor Kao hopes that their success in sequencing the genome of Mycobactrium bovis will also provide a greater understanding about how this devastating disease spreads. The name of Douglas Mawson isn't discussed along with the famous triumvirate, Scott, Amundsen and Shackleton, but one hundred years ago, he led the first science-only Australasian Antarctic Expedition. A century later, Professor Chris Turney is co-leading a repeat expedition, where scientists will repeat many of the measurements of the Mawson trip.Rising inflexion at the end of your sentences is known as "uptalk" or "valleygirl speak" and it's usually associated with young Californian females. But now a new study shows that uptalk is expanding to men. Professor Amalia Arvaniti explains that uptalk has negative connotations which makes men less likely to admit to using it, but it was clear was that this pattern of speech is like totally spreading.Waste plastic makes its way into many areas of the environment which can threaten wildlife. Small particles of plastic can also be ingested by organisms and as they act almost like sponges the plastics attract other chemicals onto their surface. Despite this their hazard ranking is the same as scraps of food or grass clippings. Dr Mark Browne from the National Centre for Ecological Analysis and Synthesis, USA, describes his new research in the journal, Current Biology, which shows that these microplastics have toxic concentrations of pollutants in which can harm biodiversity. He also explains how these microplastics transfer toxic pollutants and chemicals into the guts of lugworms. These worms have been nicknamed "eco-engineers" because they eat organic matter from the sediment and prevent the build-up of silt.Producer: Fiona Hill.

Therapeutic hypothermia is standard treatment for cardiac arrest patients to protect against the damaging or deadly repercussions of a beatless heart. But this global practice has been called into question after research in the New England Journal of Medicine reported no difference in survival rates between patients chilled to 33 degrees and those cooled to just below normal body temperature to 36 degrees. Dr Jerry Nolan, vice chair of the European Resuscitation Council tells Dr Adam Rutherford how doctors worldwide are reacting to this new study and Dr Kevin Fong, author of "Extremes, Life, Death and the Limits of the Human Body" describes how medicine has historically harnessed hypothermic states to heal.Show Us Your Instrument: The European Space Agency's GAIA mission is due to launch just before Christmas. It will spend the next 5 years recording space, using a billion pixel camera. This camera is made up of charge-couple devices, similar to the ones you'd find in your smart phone. These are damaged by space radiation. Dr Ross Burgon damages them in his lab first, to tell whether the images coming back from space are real stars or planets, or the digital equivalent of a smudge on the lens.Methane is the second most important greenhouse gas after carbon dioxide because it's 25 times more powerful than carbon dioxide at trapping the sun's rays. And it doesn't hang around as long either, ten years as opposed to a 100. So tackling methane is seen by many countries as a useful way of reducing greenhouse gases, quickly. But that depends on knowing how much there is. A new paper in the Proceedings of the National Academy of Sciences reveals that United States could be underestimating its methane emissions by as much as fifty per cent. Dr Vincent Gauci Head of Ecosystems and Biodiversity at the Open University explains how the Americans got their sums so wrong, and considers whether the British calculations are similarly suspect.The fuzzy concept of "terroir" for wine fans has always been difficult to pin down. Climate, soil, geology and individual wine-making practice don't make it easy to identify what makes particular wines unique. But Dr David Mills, Professor in the Department of Viticulture and Enology at University of California, Davis, has used DNA sequencing to study the microbial ecology of individual grapes. And he concludes bacteria and fungi could explain "microbial terroir".Producer: Fiona Hill.

Every twenty years there's a detailed survey of the birds of the UK and Ireland and today, the 2007-2011 Bird Atlas is published. Adam Rutherford hears from Dawn Balmer from the British Trust for Ornithology about the citizen scientists, the forty thousand volunteers who collected data on a staggering 19 million birds - 502 different species - and meets their record breaking volunteer, Chris Reynolds. A 73 year old retired maths teacher, Chris took part in the previous three atlases and walked thousands of miles in all seasons across his patch in the Outer Hebrides. Dawn describes the avifaunal picture revealed in this latest Atlas.In 2009, Williams developed a flywheel - which temporarily stores energy - for their formula 1 car. After the Research and Development was done, the F1 governing body changed the rules, and there was no longer space for a flywheel on their car. No matter, these things have other uses. Mark Smout from Smout Allen has proposed a design for the Isle of Sheppey in Kent, which uses banks of these flywheels to regulate the energy from the nearby wind farm. It also uses spare electricity to grow a sea defence for the island. Marnie Chesterton reports on this flywheel technology and Tim Fox, energy expert at the Institution of Mechanical Engineers describes to Adam other potential solutions for storing energy on the National Grid.Professor Bill Sutherland from the University of Cambridge is a co-author on a new "cheat sheet", published in this week's Nature, to help politicians and policy makers sort the good scientific research from the bad. He talks to Adam about why it's more important and faster, to teach a scientific approach than simply to teach facts.Producer: Fiona Hill.

Global experts in DNA identification are flying to the Philippines to assess whether they can help families to determine, beyond doubt, which of the hundreds of victims of Typhoon Haiyan are their relatives. The International Commission on Missing Persons in Sarajevo used DNA matching to identify the thousands killed in the former Yugoslavia and has since helped in conflict zones around the world. Now, working with Interpol, scientists from the ICMP are called on to assist in victim identification after natural disasters as well, and head of forensic services, Dr Thomas Parsons, tells Adam Rutherford that a team will be sent to the Philippines on Monday.The enormous ash cloud following the 2010 eruption of the Icelandic volcano, Eyjafjallajokell, grounded aircraft across Europe for more than a week and caused unprecedented disruption. Dr Fred Prata has invented a weather radar for ash, and off the Bay of Biscay, his AVOID infra red camera system, the Airborne Volcanic Object Imaging Detector, has just been tested after a ton of Icelandic volcanic ash was dropped by aeroplane into the sky. From France, Dr Prata describes the experiment and Dr Sue Loughlin, Head of Volcanology at the British Geological Survey in Edinburgh, tells Adam how Iceland has become the scientific "supersite" for seismic research.Show Us Your Instrument: Dr Glenn Gibson at the University of Reading with his Robo gut, a full-working model of the human large intestine.Liverpool University's Dr Julian Chantrey, and his PhD student have spent the past 4 years monitoring red squirrels in the Sefton area. Out of the 93 they trapped and blood tested, 5 had antibodies for the normally-deadly squirrel pox, suggesting they had contracted the pox and survived. It's early days but this could mean that reds are developing a level of resistance to the squirrel pox, like rabbits have to myxomatosis. We could be seeing evolution by natural selection in action.Producer: Fiona Hill.

A hundred thousand Britons are being asked to donate their sequenced DNA, their personal genome, to a vast database on the internet, so scientists can use the information for medical and genetic research. The Personal Genome Project-UK was launched today and participants are being warned, as part of the screening process, that their anonymity won't be guaranteed. Stephan Beck, Professor of Medical Genomics at University College London's Cancer Institute and the Director of PGP-UK, tells Dr Lucie Green that anonymised genetic databases aren't impregnable, and that it is already possible for an individual's identity to be established using jigsaw identification. This new "open access" approach, he says, will rely on altruistic early-adopters who are comfortable with having their genetic data, their medical history and their personal details freely available as a tool for research. Jane Kaye, Director of the Centre for Law, Health and Emerging Technologies at the University of Oxford, describes the rigorous selection procedure for would-be volunteers. Scientists at Queen Mary University London and Imperial have created Good Vibrations by playing pop songs to solar panels. Exposing zinc oxide PV cells to noise alongside light generated up to 50% more current than just light alone. Pop and rock music had the most effect, while classical was the least effective genre. Thanks to the Russians' enthusiasm for dash-cams in their cars, the twenty metre asteroid that came crashing into the atmosphere above the town of Chelyabinsk, East of the Urals in February this year, was the most filmed and photographed event of its kind. Mobile phones and cameras captured the meteor, moving at 19 kilometres a second (that's 60 times the speed of sound) and the enormous damage caused by the airblast. The plethora of footage allowed researchers to shed light on our understanding of asteroid impacts and in a new study, published in Nature, Professor Peter Brown from the University of Western Ontario in Canada questions whether using nuclear explosions is an appropriate way to model these airbursts and whether telescopes could underestimate the frequency of these events. Seventh November this year is the hundredth anniversary of the death of Alfred Russel Wallace. As the Natural History Museum in London unveils the first statue of him, we ask why, as co-discoverer of the theory of evolution by natural selection, Wallace doesn't share Charles Darwin's spotlight. Dr George Beccaloni, from the NHM, explains to Lucie why Wallace deserves both glory and commemoration. Producer: Fiona Hill.

A NASA spacecraft the size of a sofa is currently orbiting the Moon, gathering information about the toxic perils of moon dust. Dirt from the moon is sharp, spiky and sticky and it caused enormous problems for early astronauts as Professor Sara Russell from the Natural History Museum tells Dr Lucie Green. Joining Lucie from NASA HQ in Washington DC, Sarah Noble, programme scientist on the LADEE Mission, tells her that understanding the make-up and movement of lunar dust is vital to ensure humans can work on the Moon in the future.Electroceuticals is the new research area for medicine, tapping into the electricity transmitted through the vast network of nerves that run throughout our bodies. Kerri Smith reports on how the body's natural wiring could become a valuable tool for treating organs affected by disease. Glaxo Smith Kline has just invested £30 million into electroceuticals and researchers in labs around the world are working on devices that could "plug" into troubled organs and correct the electrical signals that have gone awry.The impact of man-made climate change tends to focus on the things we can see, like shrinking glaciers or the weather. But a study published in Nature this week by a team in Spain, focuses on the impact underground, on the make up of the soil in a sizeable part of the earth's land, the drylands. The impact of increasing aridity is dramatic, affecting the delicate balance between nitrogen, carbon and phosphorus, with serious implications for soil fertility. David Wardle, Professor of Soil and Plant Ecology at the Swedish Institute of Agriculture, tells Lucie Green that this important new study spells out the risks when delicate chemical balances are upset.Oceanographer, Helen Czerski, revealed her instrument, a giant buoy, on Inside Science's Show Us Your Instrument slot in the summer. This week, Helen is launching the buoy into the stormy seas South of Greenland, and Inside Science listeners are being called on to come up with a name ! Bob anyone ? Or Lucie's suggestion, Buoyonce ?Dogs wag their tails more to the right when they're happy and relaxed; more to the left when they're anxious. Georgio Vallortigara, Professor of Neuroscience at the University of Trento in Italy has now shown that asymmetrical tail wagging actually means something to other dogs.Producer: Fiona Hill.

Britain's legacy of nuclear waste dates back 60 plus years and a long term solution to deal with it hasn't yet been found. After this week's announcement that the UK will have a new nuclear power station, Hinkley C in Somerset, Dr Adam Rutherford asks Professor Sue Ion, former Director of Technology at British Nuclear Fuels and Chair of the European Commission's Science and Technology Committee, Euratom, how much extra waste this new plant will add to the radioactive stockpile.Eighteen years ago the first planet outside of our solar system was discovered, "51 Pegasi b". This week the tally of exoplanets passed one thousand, and as astronomer Dr Stuart Clark tells Adam, an earth twin isn't part of the planetary list.....yet.Show Us Your Instrument: Public Astronomer Dr Marek Kukula introduces the original Six Pip Masterclock at the Greenwich Observatory. This clock was used in the 1920s to send the time signals down a telephone line to the BBC, for transmission to the whole country over the radio. That's not the case now, and Adam goes down into the basement of Broadcasting House in London in search of the atomic clock that's now used to generate the Greenwich Time Signal and the famous BBC pips.iGEM is a global biology competition that allows students to build their own organisms. The UK has two teams going to the grand final next week. Adam goes to meet the team from Imperial College London, who have made a bacterium which produces plastic.Producer: Fiona Hill.

The link between genetics and a child's academic performance hit the headlines this week when Education Secretary, Michael Gove's outgoing special advisor, Dominic Cummings, called for education policy to incorporate the science behind genes and cognitive development. Mr Cummings cited the Professor of Behavioural Genetics, Robert Plomin, as a major source, and Professor Plomin tells Dr Adam Rutherford what he thinks about the way his research has been interpreted. Steve Jones, Emeritus Professor of Genetics from University College London says why he believes genetics and education is such a controversial subject. Fifty years ago, researchers tried, and failed, to teach chimpanzees English. They concluded that chimp noises were merely basic expressions of fear or pleasure. Dr Katie Slocombe from York University has shown that chimp language is far more tactical, machiavellian even, than that. The inventor of Golden Rice, the genetically modified crop, tells Adam Rutherford that he agrees with Environment Secretary, Owen Paterson, that those who attack GM crops are "wicked". Professor Ingo Potrykus from the Swiss Federal Institute of Technology in Zurich developed Golden Rice enriched with Vitamin A in 1999 and believes that opposition to GM foods has prevented the crop being grown and widely planted. But, nearly 80 years old, Professor Potrykus tells Inside Science that he still believes Golden Rice will be grown and eaten throughout the world during his lifetime. Rhys Phillips makes lightning at a Cardiff laboratory for this week's Show Us Your Instrument. It's used to test aeroplane parts. Less metal in an aircraft makes it lighter but too little and the lightning may damage the plane. The safest way to test is to make your own lightning, at ground level. Producer: Fiona Hill.

The US has shut down government science with potentially devastating results for American and international science projects. Many individual scientists are banned from talking but Matt Hourihan from the American Association for the Advancement of Science tells Dr Adam Rutherford about the serious consequences of the political squabble.Roland Pease gives the low down on this week's Nobel Prizes including the much anticipated Physics gong for Peter Higgs' for his eponymous boson.Marnie Chesterton reports on the new iCollections at the Natural History Museum where butterflies collected 150 years ago are shedding new light on the changing British climate. And after studies this week linked cardiovascular disease to aircraft noise, Kevin McConway, Professor of Applied Statistics at the Open University quantifies the risks of complex science being distorted by simple headlines.Producer: Fiona Hill.

Dr Adam Rutherford and guests explore the scientific mysteries of the menopause after scientists in the US and Japan successfully induced pregnancy in post-menopausal women.Also in the programme, we hear from decision scientist Baruch Fischhoff on the difficulties of trying to communicate uncertainty in science in the wake of the latest report from the Intergovernmental Panel on Climate Change. Following on from last week's Fracking report, one listener, Professor Kevin Anderson of the University of Manchester, raises his concerns about the consequences of exploiting shale gas for UK carbon emissions.This week's show us your instrument comes from the Rutherford Appleton Laboratory in Oxfordshire, where Dan Faircloth tends to the ISIS particle accelerator.

Fracking is touted as a technology that will lower UK energy bills. It's a controversial technique which unlocks natural gas from shale rock. But it raises many environmental concerns. So what does the science say? Adam Rutherford sorts science fact from science fiction, putting your frack FAQs to four experts. Reporter Gaia Vince travels to a gas well site in Warrington to discover the various techniques used to extract gas onshore in the UK.Also on the programme, your feedback to last week's story on new fingerprint technology.Lipstick forensics: Professor Michael Went at the University of Kent has developed a new method for unpicking the make-up of make up left at crime scenes.And this week's Show Us Your Instrument comes from Cardiff University, as we showcase herpetologist Dr Rhys Jones's snake hook. It's a low-tech but vital piece of kit for handling snakes. It's also useful for scrumping.

As Syria agrees to destroying its chemical weapon stocks, Adam Rutherford looks at how you solve a problem like Sarin. Dr Joanna Kidd from King's College London gives us a potted history of chemical weaponry. Environmental toxicologist, Prof Alastair Hay, from Leeds University has worked on chemical warfare issues for four decades. In the 1990s, he identified mustard gas and sarin residues from soil samples in Iraq, confirming their use by Saddam Hussein. He talks to Adam about the challenges of destroying chemical weapons in Syria. Reporter Roland Pease looks at a new phone app, OpenSignal, which uses your smartphone's sensors to help improve weather models. Today, London Underground workers are starting to boycott a new clock-in system, which uses their fingerprint for identification. Meanwhile, Apple fans are camping outside stores waiting to buy the new iPhone, which features a fingerprint scanner. Adam talks to Dr Farzin Deravi from the University of Kent about how fingerprint identification works and whether it can be fooled with a gummy bear. Plus he asks technology journalist Kate Bevan if we should worry about the security issues surrounding biometric passwords. Finally this week, Dr Pedro Viegas shows us his instrument - a dino drill. It's being used to uncover the Bristol dinosaur, a 210 million year old Thecodontosaurus.

As Spanish researchers unveil new stem cell research, Dr Adam Rutherford talks to Professor of Regenerative Medicine Fiona Watt. They look back at the history of stem cell research and what the future holds for regenerative medicine. Last week's discussion on science practicals generated huge amounts of feedback. Some listeners consider school practicals the secret to their success, others remember nothing more than breaking test tubes and blowing things up. Professor Robin Millar researches the best ways to teach science practicals; we ask him to respond to some of the points you raised. We unveil the mystery of the phantom head. Not an 18-rated horror film, but a dentists' training tool. This week's Show Us Your Instrument comes from Newcastle University's School of Dental Sciences. And, where there's muck, there's brass. In Newcastle, they're looking to sewage as a renewable alternative energy supply. It's flushed down the drains, but Northumbrian Water have taken a 'waste not want not' approach to our biological effluent. They are going to great efforts to recover energy from sewage and pump it back into the National Grid.

Dr Adam Rutherford asks whether the proposed ice wall around the Fukushima nuclear plant will finally halt the radioactive leaks they've suffered since the tsunami in 2011.BBC Tokyo correspondent Rupert Wingfield-Hayes gives an insider's view on the current crisis and public reaction to the £300m rescue plan announced this week. Plus, Prof Neil Hyatt from Sheffield University describes the challenges ahead in building the ice wall, and decontaminating the water used to cool the crippled nuclear reactors.Amongst the many challenges of sending a manned mission to Mars is the problem of 'menu fatigue'. Eating the same ready meals for several years could send anyone over the edge. NASA recently completed a four month Mars simulation on a barren volcano in Hawaii, their mission was to invent dishes to recreate on the Red Planet. Cooking doesn't get tougher than this.School practicals may be popular with students and teachers but recent research suggests that they might not be a useful way to teach science. Is the aim to train up the technicians of the future, or teach children how to think scientifically? Science teacher and writer Alom Shaha and Prof Jim Iley, from the Royal Society of Chemistry, discuss how to make science demo more effective. And the best way to make cheese on toast.Finally, Dr Pete Etchells from the University of Bath shows us his instrument - an eye-tracker used in psychology experiments. Recent applications include discovering why professional cricketers are better than amateurs, and whether horses are conscious.

Science is supposed to be objective. Research by Professor John Ioannidis suggests the reality is falling short of the ideal. He talks to Alice Roberts about bias in softer science disciplines, and how having an American on the team leads to more exaggerated claims for the results. Is this due to the extra pressures they face to come up with new and exciting findings? Bomb-detection dogs are currently taught each new explosive, one at a time. It's time consuming, A team at Lincoln University are investigating a new approach, categorisation. It's known that dogs can visually recognise groups of items, but can they do this with a different sense, smell? Reporter Marnie Chesterton went to Lincoln to see the team at work. This week's Show Us Your Instrument comes from The Rutherford Appleton Lab. Dr Ceri Brenner shows us the high energy Gemini laser. It can be used to research the conditions inside stars. A team at Cardiff University are harnessing the power of social media to measure, for the first time, the kinds of wildlife being killed on Britain's roads. Gruesome, yes, but assessing the problem is the first step towards conservation solutions. Seen a roadkill blackspot near you? Become a splatter spotter and do your bit for science.

Prof Alice Roberts goes Inside Science this week to discuss the science behind artificial reefs. The 70 concrete blocks around Gibraltar are currently causing a diplomatic controversy as the Spanish government claim they restrict commercial fishing. We look at how artificial reefs are made and what effect they have on the marine environment. Bees have faced multiple dangers in recent years, from pesticides to parasites. Reporter Roland Pease visits a team at the University of Bath who are putting beehives into a CAT scanner to discover whether they can help breed bees that are more resistant to disease. Humans are special; our uniquely evolved feet testify to that, allowing us to walk upright. At least, that's what anatomy students have been taught for the past 70 years. Research published his week by a team at the University of Liverpool shows that our feet are much more ape-like than we thought. And some of us may have more 'apey' feet than others. Finally, this week Prof Andrea Sella from University College London shows us his instrument - an NMR spectrometer. This magnetic beast determines not only the chemical composition of molecules, but also their 3D structure.

Influenza causes up to five million cases of severe illness and half a million deaths globally every year. Yet, as Adam Rutherford finds out, our current vaccination strategy is a seasonal game of chance, based on guessing the strain that will appear next. Research published this week in Science Translational Medicine, by a team from Mount Sinai Hospital in New York, offers hope for a universal flu vaccine, based on newly discovered antibodies. Earlier this week, a game to help combat ash dieback was launched on Facebook, called Fraxinus. Reporter Gaia Vince looks at the growing trend for using games to solve scientific problems. Is this new way of gathering and analysing data changing the way science is done? Currently half of all clinical trials are not published worldwide. Adam talks to Ben Goldacre, author of Bad Pharma, about his new campaign 'AllTrials', which aims to change that. Finally this week, physicist Peter Barham shows us his instrument - a spy camera system that he's designed to recognise penguins.

Cultured meat was on the menu earlier this week, but Mark Post's public tasting of his lab-grown burger marks the culmination of decades of research on producing artificial meat. Adam Rutherford talks to one of the other major players in the world of manmade animal products, Gabor Forgacs. However, his company, Modern Meadow, is concentrating on launching a different product first - cultured leather. The football season is about to start, and for the first time electronic Goal Line Technology will be introduced. This year will see the Hawk-Eye system deployed at all Premier League grounds in an attempt to help referees make more informed decisions. But how will it work, and how accurate can it be? Inside Science speaks with the inventor, Paul Hawkins, and the engineers who are testing it to international standards. A bacteria or a bacterium? We sparked a controversy on last week's programme by using bacteria to describe a singular microbe. Adam talks to evolutionary biologist Mark Pagel about how words evolve and whether scientists can halt their adaptation. This week on 'Show Us Your Instrument', oceanographer Helen Czerski introduces her giant marine buoy. She'll be sailing into the eye of a storm just off the south coast of Greenland later this year, where the buoy will measure bubbles to help refine climate models.

July has seen train crashes in Canada, Pakistan, France, Spain and Switzerland. Inside Science asks if this is a trend or just a coincidence. Professor David Spiegelhalter, an expert in the public perception of risk, explains whether there is such a thing as a 'crash season'. Microbiologists working on the Mary Rose in Portsmouth have discovered a new type of metal-eating bacteria which is damaging the ship's wooden timbers. Reporter Gaia Vince goes behind the scenes at Portsmouth's Historic Dockyards to find out how conservation scientists have saved the ship. Last week Manchester hosted the 2013 International Congress of History of Science Technology and Medicine, the biggest ever meeting of historians of science from around the world. The keynote speech was given by Prof Hasok Chang of the University of Cambridge, urging his colleagues to put "Science back in History of Science". Inside Science asked him if there should also be more history in the practice of science... Finally, Dr Marek Kukula Public Astronomer at the Greenwich Observatory shows us his instrument - the 28inch refracting telescope which historians at the time likened to a Spanish onion, or the Taj Mahal.

Nobel Prize and - as of this week, Copley Medal - winner Andre Geim outlined in Nature today his vision for the next generation of super-materials. Chemist Prof Andrea Sella joins Adam to explain how the discovery of graphene may have been the start of a remarkable new class of tailor made materials technically known as 'Van der Waals heterostructures'.This week on Show Us Your Instrument, Prof Sophie Scott introduces the MRI machine and explains why you never press the 'quench' button, unless you want to blow the roof off.Finally, an exhibition on Antarctic architecture opens on Friday 26th July in Glasgow, commissioned by the British Council and curated by The Arts Catalyst. We talk to Hugh Broughton who designed the new Halley VI base, a Thunderbirds inspired building, perched on top of stilts, on top of skis.Plus, Adam calls the current Halley Base Commander, Agnieszka Fryckowska, to find out what it's like to live and work during three months of darkness.Producer: Michelle Martin.

Wendy Jarrett of the organisation Understanding Animal Research shares her thoughts.We hear from amateur and professional would-be astronauts about their training regime and selection process from Major Tim Peake, the UK’s next astronaut, to science broadcaster, Sue Nelson.Plus, the first in our new series ‘Show Us Your Instrument’. Material scientist Mark Miodownik introduces the wonders of the Transmission Electron Microscope, with music composed by the New Radiophonic Workshop.

Scientists investigate viruses in order to save lives. But could that same knowledge also help other people create dangerous viruses to use as weapons of terror? This Thursday evening, a public debate is being held by the Society of Biology around these issues of "Dual Use" research. In an age of synthetic biology, mail order genes, and open access publication, what are the pros and cons of sharing virology research? Also this week, a new centre for research into synthetic diamonds was opened by UK Science Minister David Willetts. Inside Science reporter Marnie Chesterton took a tour of the new facility to find out how diamonds might be a quantum computer's best friend. Plus, the first formal trial of a stem cell based organ transplant is happening in the UK. Martin Birchall from University College London is working on replacing the larynx. But if a patient receives a new voicebox from a donor, whose voice will they have?
