KQED serves the people of Northern California with a public-supported alternative to commercial media. Home to the most listened-to public radio station in the nation, one of the highest-rated public television services and an award-winning education program, and as a leader and innovator in interactive technology, KQED takes people of all ages on journeys of exploration — exposing them to new people, places and ideas.
Why are health officials so worried about swine flu? A major reason is that against it, we are almost defenseless. Apart from the drugs Tamiflu and Relenza, which must be taken in the first 48 hours, swine flu is untreatable. The swine flu scare is only the latest chapter in an ongoing arms race between humans and viruses. But some scientists believe the end may be in sight.
It's easy to get excited about installing solar panels on our houses, but most of us could significantly cut our energy bills for less with a simple trip to Home Depot. Thanks to the new federal stimulus package, $411 million is coming to California to help the state's buildings become more energy efficient.
Thanks to the new federal stimulus package, $411 million is coming to California to help the state's buildings become more energy efficient. One program, which helps low-income families weatherize their homes, is seeing its budget triple. Check out images from our radio story as one home is weatherized.
For the last 18 years, Lawrence Berkeley National Laboratory has had the physics equivalent of a rusty pickup truck parked in its front yard. Now, the 1950s era Bevatron is being demolished, and a chapter in the Bay Area's history of high level physics research comes to a close.
How do we know that the climate is changing? In this video, provided by scientist Kendrick Taylor, learn how 8-foot long ice core samples extracted from deep in the ice layer of Antarctica hold key evidence of rapidly changing climactic conditions.
President Obama's stimulus plan set aside billions for clean energy. Funding will go to some familiar projects — like wind and solar power — and to some not so familiar ones, like the smart grid. So what is the smart grid? And how will it affect your home energy use?
Call them demolition derby astrophysicists: NASA scientists in Mountain View deliberately crashed an unmanned rocket into the moon on October 9th, 2009. Their goal? To find water, in the form of ice, which could one day support a moon base. On November 15th, 2009, they announced they had found it. QUEST looks at the planning and run-up to the big event.
How much sewage makes its way into our water? Plenty. Statewide, it's likely that last year's record number, 20 million gallons of raw sewage dumped in California waterways, is going to be broken this year. Decrepit pipes, lack of money and the growing severity of storms could all add up to a disaster of septic proportions.

Most scientists agree that using nuclear explosives to deflect an incoming asteroid is a bad idea. But Astrophysicist David Dearborn from Lawrence Livermore National Laboratory has been heating up the debate with his theories about how nuclear explosives could be used effectively to nudge an asteroid into a new orbit that causes it to miss the Earth entirely.
Everyone knows that eight planets orbit the Sun. But thousands of other objects, including icy comets and football field-sized asteroids, are also zooming around our solar system. And some of them could be on a collision course with Earth. QUEST explores how these Near Earth Objects are being tracked and what scientists are saying should be done to prevent a deadly impact.
