Hey Science Diction listeners! We’re back to tell you about a brand new show from Science Friday. Universe Of Art is a podcast about artists who use science to take their creations to the next level.Hosted by SciFri producer and musician D. Peterschmidt, each episode of Universe Of Art will focus on a different artist (or scientist) about how science played a role in their creative process, and what we can learn by combining two seemingly unrelated fields together. We’ll hear from astronomers who integrate space into their artwork, drag performers who bring science into their acts, and many others. Here’s a sneak peak.Listen to Universe Of Art wherever you get your podcasts.

Dear Science Diction listeners, It is with sadness that we announce the finale of the Science Diction podcast. Starting with a simple newsletter and a passionate audience, the Science Diction podcast grew to serve up episodes on topics as varied as meme, ketchup, and juggernaut. It has been a joy to share these stories with you for the last two years. In celebration of Science Diction, we are sharing with you now a final mini-episode, a look back on this labor of love. You can relisten and read past editions of Science Diction anytime by visiting www.sciencefriday.com/ScienceDiction. If you find yourself longing for more science esoterica, we invite you to join us at our weekly trivia nights. Hosted by Diana Montano and a variety of guest experts, they are a free, and absolutely nerdy, delight. On behalf of Johanna, Elah, and everyone that has contributed to making Science Diction, thank you for listening!

We have a favor to ask! We want to know more about what you like, what you don’t, and who you are—it’ll help us make better episodes of Science Diction. Please, take our brief survey. Thank you! At the turn  of the 20th century, the American chestnut towered over other trees in Eastern  forests. The trees would grow as much as 100 feet high, and 13 feet wide. According to legend, a squirrel could scamper from New England to Georgia on the canopies of American chestnuts, never touching the ground. And then, the trees began to disappear, succumbing to a mysterious fungus. The fungus first appeared in New York City in 1904—and  then it spread. By the 1950s, the fungus had wiped out billions of trees, and effectively finished off the American chestnut. Now, some people are trying to resurrect the American chestnut—and soon. But not everyone thinks that’s a good idea. Guests:  Sara Fitzsimmons is Director of Restoration, North Central Regional Science Coordinator, and Regional Science Coordinator Supervisor at the American Chestnut Foundation.  Susan Freinkel is the author of American Chestnut: The Life, Death, and Rebirth of a Perfect Tree. ​​Neil Patterson Jr. works at the Center for Native Peoples and the Environment at SUNY, and is a member of the Tuscarora Nation.  Bart Chezar is a chestnut enthusiast, and volunteers with the Prospect Park Alliance.

For decades, vocal fry lived a relatively quiet existence. It was known to linguists, speech pathologists and voice coaches, but everyday people didn’t pay much attention to it. But then in 2011, people started noticing it everywhere. So what happened? What is vocal fry? Why does host Johanna Mayer use it? What's her problem? And is it really that bad? Guest:  Lisa Davidson is the chair of the Linguistics Department at NYU.

In 2014, a grad student in Kolkata named Ujaan Ghosh came across an old book by a Scottish missionary. And as Ghosh paged through the book, he noticed the missionary kept using a word over and over: Juggernaut. But the missionary wasn’t using it the way we do today—to mean an unstoppable, overwhelming force. He  was using it to talk about a place: a temple in Puri, India. So Ghosh dug further, and as he grasped the real story of where the English word, juggernaut, had come from, he realized there was just no way he could keep using it. A transcript of this episode is being processed and will be available within a week. Guests:  Chris Egusa is an audio producer and 2020 KALW Audio Academy fellow.

Head on over to plainlanguage.gov, and you’ll find a helpful table, dedicated to simplifying and demystifying military jargon. On one side of the table, there’s the jargon term, and on the other, its plain language equivalent. “Arbitrarily deprive of life”? Actually just means “kill people.” “Render nonviable”? Also means “kill people.” “Terminate with extreme prejudice”? “Kill people.”    This table is just one of many resources on plainlanguage.gov—from checklists to plain language training to thesauruses. The website was created by an unfunded government group of plain language activists who make it their mission to translate government communications into regular old, plain language.  But jargon isn’t just a government problem. It pops up in nearly every field, and it seems like it annoys most of us. So why do we use it? And is there anything actually good about it?   This episode was inspired by a question from a listener, Jafar, who asked about the word “recrudescence” and why we tend to use fancy words when simple ones would work just fine.

CORRECTION: In this episode, we say that there were only two names left on the 2021 list of Atlantic hurricane names until we resume use of the Greek alphabet letters. In March 2021, the World Meteorological Association decided to end the use of the Greek alphabet, and provided a list of supplementary names instead.   This episode is a re-broadcast. It originally aired in November 2020.  Every year, the World Meteorological Organization puts out a list of 21 names for the season’s hurricanes and tropical storms. But in 2020, the Atlantic hurricane season was so active that by September, we'd flown through the whole list of names and had to switch to the Greek alphabet. Thus, Hurricane Iota became the 30th named storm of the season. We’ve only had to dip into the Greek alphabet once before, in 2005. But the practice of naming hurricanes goes back to the 19th century, and it was a bumpy ride to land on the system we use today. In this episode: The story of a meteorologist in Australia, a novel, and a second-wave feminist from Florida—and how they brought us hurricane names. Guests: Christina M. Gonzalez is a doctoral candidate in anthropology at the University of Texas at Austin.Liz Skilton is a historian and the author of Tempest: Hurricane Naming and American Culture.

When Isabel Briggs Myers imagined that her homegrown personality test would change the world, she couldn’t have pictured this. Today, millions take the Myers-Briggs Type Indicator each year. Countless organizations use it, from General Motors to the CIA. But there’s one field that mostly rolls its eyes at the test: psychology.  In our final chapter, Isabel rescues her indicator from the verge of extinction, but has to make some compromises. And we explore what the Myers Briggs does (and doesn’t) measure, and why people love it despite psychologists' complaints. Listen to Chapter 1 and Chapter 2 of this series. Guests:  Merve Emre is a writer and English professor at the University of Oxford. Annie Murphy Paul is a science journalist and author.   Dan McAdams is a professor of psychology at Northwestern University.  Quinisha Jackson-Wright is a writer and the author of Working Twice as Hard.  Jeffrey Hayes is the President and CEO of the Myers-Briggs Company.

At first, it seemed like Isabel Briggs Myers would have nothing to do with personality typology. That was her mother Katharine’s passion project, not hers. But when Isabel enters a tumultuous marriage, she discovers that her mother’s gospel of type might just be the thing to save it.  In Chapter 2, Isabel picks up her mother’s work, and decides to transform it into a marketable product—but first, she has to convince a group of skeptical PhDs that it actually works. Along the way, one particularly dogged researcher notices some issues with her indicator, threatening to undo everything she’d worked for. If you’re new to the series, listen to Chapter 1.

If you’re one of the 2 million people who take the Myers-Briggs Type Indicator every year, perhaps you thought Myers and Briggs are the two psychologists who designed the test. In reality, a mother-daughter team created the test essentially at their kitchen table. In this episode, we look at the unlikely origins of the Myers-Briggs, going all the way back to the late 1800s when Katharine Cook Briggs turned her living room into a “cosmic laboratory of baby training” and set out to raise the perfect child. In this three-part series, we uncover the strange history of the most popular personality test in the world, and how two women revolutionized personality testing—for better or for worse.  Guest:  Merve Emre is a writer and English professor at the University of Oxford.

Honeymoon: It just seems like a word that would have a lovely story behind it, doesn’t it?  When a listener named Eric emailed us from Centerville, Ohio asking about the word, that’s what we were hoping to find. Instead, we found a more bittersweet origin stretching all the way back to an early modern poem. Plus: We take a look at what’s going on in our brains during the honeymoon period—and whether it’s all downhill from there.  If you want us to cover a word on the show, get in touch!

In 1910, a fruit fly geneticist named Thomas Hunt Morgan noticed something strange in one of his specimens. Out of his many, many fruit flies—all with brilliant red eyes—a single fly had white eyes. This fruit fly turned out to be a very big deal. From those white eyes, Morgan eventually figured out that genes can be sex-linked, confirmed that genes exist on chromosomes, and won the Nobel prize. But he also cemented his legacy another way, with what he chose to name that gene: "white". It might sound uninspired, but it kicked off a tradition that decades later gave us names like spatzle, hamlet, and ken and barbie. Here and there, a name went too far, but overall, fanciful names brought joy to researchers and worked well until genes like these were discovered in humans, and everything went awry. Johanna and Senior Producer Elah Feder team up with Helen Zaltzman of The Allusionist to talk about fruit flies, genes, and whether it’s ok to name a gene after a German noodle. Plus, after much demand, we bring you... the origin of "defenestration"! Guests: Helen Zaltzman is the host of The Allusionist.

If you read the title of this episode and cringed, you’re not alone. At Merriam-Webster, editors and lexicographers receive countless letters grousing about the addition of certain words to the dictionary. And here at Science Diction, we get our fair share of emails pointing out our linguistic missteps.  But the more you dig into the origins of words, the more you notice that when it comes to language, “correctness” is a slippery concept. In fact, some of our most beloved English words - nickname! newt! - were born of mistakes.  In this episode, Merriam-Webster lexicographers Emily Brewster and Peter Sokolowski explain the mistake-ridden origins of our words, how language evolves, and how wrong becomes right. Plus, we answer a listener question about the most exported word in the English language.

When the first COVID-19 vaccines were approved for emergency use last December, it felt like - at last! - our nightmare was nearly over. Then came reports of botched distribution efforts, from broken websites to factory mix-ups. Scientists created the vaccine in record time, but it was beginning to look like that might’ve been the easy part. But if you think vaccine distribution was a logistical nightmare in 2021, try doing it in the early 1800s. In 1796, Edward Jenner discovered that cowpox worked as a vaccine against smallpox. All you had to do was pop a cowpox sore on someone’s skin and transfer the lymph fluid (a.k.a. pus) into a cut on a second person. Soon, they'd develop a few sores, but when they recovered, they'd be immune to smallpox, a far more serious disease. This worked well enough for short distances, but when smallpox began to destroy Spanish colonies in the Americas, Spain had to figure out a way to move the vaccine across the ocean. Their solution was resourceful, effective, and very ethically dubious. Science writer Sam Kean brings us the story of the world's first vaccination campaign. Guest:  Sam Kean is a science writer, author of The Bastard Brigade, and host of the podcast Disappearing Spoon from the Science History Institute.

In 2013, introverts staged their comeback. For decades, they’d been told to get out of their shells and *smile*, while those  showy, gregarious extroverts were held up as the American ideal. But when one author published a kind of introvert’s manifesto, she sparked an introvert pride movement. Since then, the war of the ‘verts has only escalated, with self-identified introverts accusing extroverts of being shallow and incessantly chatty party monsters, and extroverts declaring introverts self-absorbed shut-ins who are just jealous because extroverts are actually happy. (A contention that studies support.) It all feels like a very 21st Century, internet-era drama. But the history of the dubious and divisive introvert-extrovert binary began 100 years ago, when Carl Jung fell out with Sigmund Freud, and tried to make sense of where they’d gone wrong. In the process, Jung coined a couple of new terms, and unleashed an enduring cultural obsession with cramming ourselves into personality boxes.

In 1953, in the coastal town of Minamata in Japan, locals noticed some cats were acting strangely—twitching, spinning in circles, almost dancing. The reality was far darker. What looked like dancing was really convulsions. The cats drooled, spun in circles, and flung themselves into the sea. The cause of this strange behavior, residents discovered, was mercury. Mercury—a silvery liquid, named for a quick-footed Roman God—has captivated humans since ancient times. It’s found in Egyptian tombs that date to 1500 BCE, and the first emperor of unified China believed it was the elixir of life. But what happens when it invades a town, and seeps into our brains?

Vervet monkeys steal it out of people's hands. Chimpanzees in Guinea are known to climb up palm trees and drink it. There’s even a theory that loving it was an important adaptation for our pre-human ancestors, that the smell of fermentation helped them track down very ripe, calorie-rich fruit.  Alcohol has been deeply ingrained in our lives from the beginning, possibly since before we were human. And while the drive to drink is older than civilization, many have worked hard to reign it in. In 1920s America, these desires clashed like never before. It’s a story of a battle between chemists, and the unthinkable lengths the U.S. government went to to try to pry away our favorite mind-altering substance.

In 1920, a Czech writer was stumped. He’d written a play about a future where machines that looked like people do our bidding. They were the perfect workers: obedient, hard working, and never demanded a pay raise. But what was the writer to call these marvelous machines? There wasn’t yet a word for this type of creation.  He had initially chosen labori, from the Latin for labor, but something about the word wasn’t quite right. It seemed...stiff, bookish. This play wasn’t just about machines who labored. It was about machines we exploited, relentlessly. And eventually, the writer landed on a word that fit better: Robot.  Robot comes from an old Czech word for drudgery and servitude. Though in his play - like so very many robo-dystopias to come - the writer showed that a mind we create to serve us, isn’t necessarily a mind we can control.

On December 5th, 2012, a bill landed on President Barack Obama’s desk, meant to do one thing: remove the word “lunatic” from the federal code. This is because in 2012, you could still find the word in laws about banking and controlling estates, among others. And not only was it offensive, it was antiquated—ancient, in fact. The word lunacy comes from luna—Latin for moon. This is because there was a time when we thought the power to change our moods and minds came from the sky.

In the late 18th century, a doctor showed up in Paris practicing some very peculiar medicine. He would escort patients into dimly lit rooms, wave his arms over their bodies, and touch them with a magnetic wand. Patients would react to these treatments violently: crying, sweating, convulsing or shrieking. But then they would emerge healed. According to the doctor anyway. Many believed he was a fraud, but despite his dubious methods, this doctor inadvertently gave us a new approach to healing—and a new word: mesmerize. Because the doctor’s name was Franz Anton Mesmer.  A depiction of Mesmer’s “treatment” baquets.

Science Diction is back with a new season all about mind control—what happens when we decide to create new minds and they refuse to be controlled, why we’ve long believed the moon had the power to control our minds, and the extremes the government has gone to in order to pry us away from our favorite mind-altering substance.  The first episode of our new season drops February 9th. Listen to a sneak peek above.

How did we wind up with a storm named Iota? Well, we ran out of hurricane names. Every year, the World Meteorological Organization puts out a list of 21 names for the season’s hurricanes and tropical storms. But this year, the Atlantic hurricane season was so active that by September, we'd flown through the whole list of names and had to switch to the Greek alphabet. Thus, Hurricane Iota became the 30th named storm of the season. We’ve only had to dip into the Greek alphabet once before, in 2005. But the practice of naming hurricanes goes back to the 19th century, and it was a bit of a bumpy ride to land on the system we use today. In this episode: The story of a meteorologist in Australia, a novel, and a second-wave feminist from Florida—and how they brought us hurricane names. Guests:  Christina M. Gonzalez is a doctoral candidate in anthropology at the University of Texas at Austin.Liz Skilton is a historian and the author of Tempest: Hurricane Naming and American Culture.

The first Oreo rolled out of Chelsea Market in Manhattan in 1912, but despite the cookie’s popularity today, Oreos weren’t an immediate cookie smash hit. In fact, there was already another cookie on the block that looked remarkably similar to Oreos: two chocolate wafers embossed with laurel leaves, and white cream in the center. This cookie was widely loved, made with the highest quality ingredients, and saddled with a curious name: Hydrox. So how did a cookie get a name so bad? Producer Alexa Lim takes us all the way back to the early 1900s, and brings us a story of the rise - and the crumble - of a cookie named Hydrox.   Guests:  Carolyn Burns is the owner of The Insight Connection, and a former marketing director for Keebler.

In the 1760s, a new kind of establishment started popping up in Paris, catering to the French and fancy. These places had tables, menus, and servers. They even called themselves “restaurants,” and you might have too, were it not for one key difference: these restaurants were places you went not to eat. Well, not to chew anyway. Because they weren’t in the business of feeding their genteel clientele, but of soothing their frayed nerves —with premium medicinal soups. Soups which were also called “restaurants”! In this episode: How restaurants evolved from a soup to a chic Parisian soup spa to the diverse, loved—and sorely missed—solid food eateries of today.

Salty, sweet, sour, bitter. Scientists once thought these were the only tastes, but in the early 20th century, a Japanese chemist dissected his favorite kombu broth and discovered one more: umami. In recent years, umami has become a foodie buzzword, but for nearly a century, the Western world was in full-blown umami denial—didn’t believe it existed. And we might have stayed that way if it weren’t for our most notorious and potent source of umami: MSG.   A 1930s advertisement for Ajinomoto.

This week, we’re sharing an episode from an excellent food podcast, Gastropod. This show is right up our alley—co-hosts Cynthia Graber and Nicola Twilley serve up episodes that “look at food through the lens of science and history.” What’s not to love? This episode looks at something we’re all missing a lot these days: communal eating.  We love eating dinner together with friends and extended family, and we miss it! But why does sharing a meal mean so much—and can we ever recreate that on Zoom? As we wait for the dinner parties, cookouts, and potlucks of our post-pandemic future, join us as we explore the science and history of communal dining. Scientist Ayelet Fishbach shares how and why eating together makes us better able to work together, and evolutionary psychologist Robin Dunbar and archaeologist Brian Hayden demonstrate how it actually made us human—and led to everything from the common cow to the pyramids. Plus, we join food writers Nichola Fletcher and Samin Nosrat for the largest in-person banquet of all time, with Parisian waiters on bicycles, as well as the world’s biggest online lasagna party. Guests:  Samin Nosrat is a chef, teacher and author of Salt, Fat, Acid, Heat. Ayelet Fishbach is professor of behavioral science and marketing at the University of Chicago. Robin Dunbar is a professor of evolutionary psychology at the University of Oxford. Brian Hayden is an archaeologist and emeritus professor at Simon Fraser University. Nichola Fletcher is a food writer in Scotland and author of the book Charlemagne’s Tablecloth: A Piquant History of Feasting. Alice Julier is a sociologist who writes about inequality, food, and everyday life.  Footnotes & Further Reading:  Listen to more Gastropod here.

Rocky Road is just a good name for an ice cream flavor. So good, in fact, that two ice cream institutions have dueling claims to Rocky Road’s invention. It’s a story of alleged confessions and a whole lot of ice cream-fueled drama. If it were just the flavor that made Rocky Road so special, every company could have just made their own concoction of nuts, chocolate, and marshmallows, named it “Muddy Street” or “Pebble Lane,” and called it a day. But there’s a linguistic reason why Rocky Road just sounds so dang delicious—and it’s studied by linguists and marketers alike. Fenton's Creamery in Oakland, California, one of the institutions that lays claim to inventing Rocky Road. (Wikimedia Commons)     In this episode, we mention the Bouba Kiki Effect. Imagine two shapes: One is a pointy, jagged polygon, the other an ameboid-like splotch. Which shape would you name “Bouba,” and which would you name “Kiki?” In study after study, 90% of people agree—the pointy shape is “Kiki” and the rounded shape is “Bouba.” This so-called “Bouba-Kiki Effect” holds in many languages, and has even been demonstrated with toddlers. But why the near-universal agreement? Cognitive psychologists like Kelly McCormick have several theories.

At the turn of the 20th century, 12 young men sat in the basement of the Department of Agriculture, eating meals with a side of borax, salicylic acid, or formaldehyde. They were called the Poison Squad, and they were part of a government experiment to figure out whether popular food additives were safe. (Spoiler: Many weren’t.) Food manufacturers weren’t pleased with the findings, but one prominent ketchup maker paid attention. Influenced by these experiments, he transformed ketchup into the all-American condiment that we know and love today. Except ketchup—both the sauce and the word—didn't come from the United States. The story of America’s favorite condiment begins in East Asia. Harvey Wiley (back row, third from left) and the members of The Poison Squad. (U.S. Food and Drug Administration) Members of the Poison Squad dining in the basement of the Department of Agriculture. Harvey Wiley occasionally ate with them, to offer encouragement and support.

We’ve all been thinking about food a lot lately. Whether you’re on the sourdough starter train, treating yourself to takeout, or you finally have the time to cook your way through a book of family recipes, food feels omnipresent these days. So, for the next few weeks at Science Diction, we are all about the science, language, and history of food! If you like your meal with a sprinkle of etymology, a dash of history, and a side of science, these episodes of Science Diction will hit the spot. Here's a sneak peek!

In the fall of 1918, Philadelphia newspapers announced that a new virus had arrived in the city, the so-called “Spanish flu.” But the facts and scope were muddy and uncertain, and the city decided to push forward with a highly-anticipated parade. About 200,000 people showed up, and packed onto sidewalks. Halfway across the country, St. Louis, Missouri looked very different that fall. Businesses shuttered, movie theatres went dark, and students stayed home.  Just like today, cities across the U.S. responded to the 1918 influenza pandemic differently—with very different results.  In this episode, we go back to 1918 and a pandemic which wasn’t Spanish at all. Footnotes And Further Reading:  Get into the nitty gritty of viral evolution with "1918 Influenza: the Mother of All Pandemics” which reviews the 1918 pandemic and all outbreaks it later spawned. The CDC’s Pandemic Influenza Storybook paints a vivid picture of life during the pandemic. We first learned about Philadelphia’s Liberty Loan Parade from the Washington Post’s reporting. For this story, we read many old articles from newspapers across the country, all archived on newspapers.com (available with a subscription). Credits:  Science Diction is hosted and produced by Johanna Mayer. Our producer and editor is Elah Feder. We had additional story editing from Nathan Tobey, and fact checking help from Michelle Harris. Our composer is Daniel Peterschmidt.

Quarantine has been on many of our minds lately. The phrases “shelter in place” and “self-quarantine” have filled up our news, social media, and conversations since the first inklings of the coronavirus pandemic. But this is far from the first time cities and countries have used the practice of physical separation to battle the spread of disease.  You might think of Mary Mallon, who many know as “Typhoid Mary.” In the early 1900s, she spent nearly 30 years  in a cottage on a small island in New York City’s East River, all to prevent her from infecting others. But we’ve been using quarantine for millennia—well before we even understood germs existed and that they can be transmitted from person-to-person. And the origin of the word stretches all the way back to the mid-14th century, when Europe was swept by one of the biggest losses of human life in history: the Black Death.

For centuries, smallpox seemed unbeatable. People had tried nearly everything to knock it out—from herbal remedies to tossing back 12 bottles of beer a day (yep, that was a real recommendation from a 17th century doctor), to intentionally infecting themselves with smallpox and hoping they didn’t get sick, all to no avail. And then, in the 18th century, an English doctor heard a rumor about a possible solution. It wasn’t a cure, but if it worked, it would stop smallpox before it started. So one spring day, with the help of a milkmaid, an eight-year-old boy, and a cow named Blossom, the English doctor decided to run an experiment. Thanks to that ethically questionable but ultimately world-altering experiment (and Blossom the cow) we got the word vaccine. Want to stay up to speed with all things Science Diction?

Remember that summer when the internet was one Distracted Boyfriend after another—that flannel-shirted dude rubbernecking at a passing woman, while his girlfriend glares at him? Everyone had their own take—the Boyfriend was you, staring directly at a solar eclipse, ignoring science. The Boyfriend was youth, seduced by socialism, spurning capitalism. The Boyfriend could be anyone you wanted him to be.    We think of memes as a uniquely internet phenomenon. But the word meme originally had nothing to do with the internet.

Cobalt has been hoodwinking people since the day it was pried from the earth. Named after a pesky spirit from German folklore, trickery is embedded in its name.   In 1940s Netherlands, cobalt lived up to its name in a big way, playing a starring role in one of the most embarrassing art swindles of the 19th century.

At the turn of the 19th century, Britons would stroll along the Yorkshire Coast, stumbling across unfathomably big bones. These mysterious fossils were all but tumbling out of the cliffside, but people had no idea what to call them. There wasn’t a name for this new class of creatures.  Until Richard Owen came along. Owen was an exceptionally talented naturalist, with over 600 scientific books and papers. But perhaps his most lasting claim to fame is that he gave these fossils a name: the dinosaurs. And then he went ahead and sabotaged his own good name by picking a fight with one of the world’s most revered  scientists. Want to stay up to speed with Science Diction? Subscribe to our newsletter.

From the people who make Science Friday, we bring you Science Diction, a bite-sized podcast about words—and the science stories behind them. Hosted by SciFri producer and self-proclaimed word nerd Johanna Mayer, each episode of Science Diction digs into the origin of a single word or phrase, and, with the help of historians, authors, etymologists, and scientists, reveals a surprising science connection. For example, did you know the origin of the word meme has more to do with evolutionary biology than lolcats? Here's a sneak peek!
