Can brain performance be improved? The $300 million-a-year "brain-fitness" industry is betting that the answer to that question is yes. Some companies say that an 80-year old brain can perform just as well as a 25-year old brain after some specialized video game training. What about crossword puzzles and regular old exercise? QUEST takes a look at the growing brain fitness industry and the science behind it.
The general idea is that by doing a series of basic and repetitive tasks, which get harder over time, you’re actually changing your brain structure. Over time, the manufacturers claim, you can train an old brain to behave like a new one. But many scientists who study aging are skeptical.
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 and corporate office parks, clean tech entrepreneurs in Silicon Valley are plugging into an emerging electric car industry.
Every year buzzwords enter the American lexicon. Like "octo-mom" or "crowdsourcing." Next year "range anxiety" may top the list. It's the fear of being stranded in an electric car because the battery has run out. Andrea Kissack continues to explore the brave new world of electric cars. Today, she goes in search of a charge.
The first mass-produced electric vehicles ever sold in the United States will begin to hit auto show rooms by the end of this year. The Nissan Leaf and the Chevy Volt already have tens of thousands of pre-orders. Until now, electric cars had been the domain of small groups of tech hobbyists and hard core environmentalists. But how feasible are they for everyday drivers? Take a drive with Andrea Kissack and find out.
In 1969, there were 65 days when Bay Area air quality exceeded federal health standards. Under those same standards, last year, there wasn’t a single day over the limit. On the 40th anniversary of the Clean Air Act, we examine the impacts that the law has had on public health, business, and environmental justice in the Bay Area and what still needs to be done to improve the quality of our air.
Deepak Srivastava – profiled in this week's radio story – is no stranger to QUEST. Just last month, Srivastava made headlines when he announced that his lab had successfully created beating heart cells from adult cells.
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.
The wireless age has introduced countless devices that many of us can't live without, like cell phones, laptop computers and wifi routers. Like all electronics they communicate using electromagnetic frequencies – or EMFs. Some people worry that EMFs are making them sick – and say that technology should slow down, as Amy Standen reports.
Oakland's Historic Lake Merritt is in the midst of a multimillion dollar face lift.

This is the classic environmental story: a species in trouble because of what our species is doing. It's happening all over the world. But there are people tackling these problems one by one, coming up with simple ways of changing our behavior. This week we take a look at the plight of the foothill yellow-legged frogs.
