QUEST takes a look at the growing brain fitness industry and the science behind it.

Silicon Valley: The New Detroit?
Detroit has been at the center of the country’s auto industry ever since Henry Ford rolled his first Model T off the assembly line in 1908. But as hard times have fallen on America’s Rust Belt, there's a new region hoping to give Detroit a run for its money. Amidst start-up companies like Google, eBay and Facebook, clean tech entrepreneurs in Silicon Valley are plugging into an emerging electric car industry. Andrea Kissack tells us more.

Backyard Seed Banks
It’s the time of year when backyard gardeners are gathering the last few tomatoes and squash of the summer harvest. But there’s one thing most gardeners don’t harvest: seeds. Seed saving is a technique that has fallen by the wayside in modern agriculture. The idea is to develop plants that are suited for the Bay Area's microclimates and to preserve crop biodiversity. As Lauren Sommer reports, a handful of people are starting their own seed-saving efforts.

California Takes the Lead on Stem Cell Research
A judge's ruling last month that blocks the federal government from funding embryonic stem cell research puts California back in the lead in the field. Scientists say funding from a 2004 state ballot measure has become a lifeline for pioneering work on diseases like Parkinson's and congenital heart disease. Still, the ruling, which may be overturned on appeal, will create challenges in California.

Cow Power Not Cutting It
Take a waste product like cow manure or trash, let it decompose for a bit and you’ll soon end up with methane gas. Methane is powerful contributor to climate change. But it can also be captured and used to make renewable electricity. That’s something farmers are experimenting with across California. But by solving one environmental problem, they’re running headlong into another. Lauren Sommer has more.

Communities are scuttling plans for microwave communication dishes in their neighborhoods, citing health concerns about EMFs. Fairfax is just the latest city to put a moratorium on "smart meters" - which transmit energy information wirelessly. So what are EMFs, and how do they affect us?

Mass Transit Housing Plan
A single-family home with a yard and two-car garage may be the American dream for many Californians. But with real estate at a premium and traffic congestion getting worse, there is a new urban way of living that is becoming increasingly popular. Quest reports on the rise of the transit village and just why the trend has taken so long.

Investigating Darwin's Legacy
This year marks the 200th birthday of Charles Darwin - and the 150th anniversary of his landmark work, "On the Origin of Species". One of the iconic fossils that supports Darwin's theory of evolution is called the Archaeopteryx and it was recently flown out to Stanford University for an unusual test. Scientists are bombarding this dino-bird with high-tech gadgetry to unlock even more information about how we came to be here.

Every year pilots in the U.S. report more than 7,000 bird strikes. The Sacramento International Airport has one of the highest incidences of bird strikes in the nation, thanks to its location next to the Pacific Flyway.
