What would an earthquake early warning look like?
California is hungry for renewable energy. Solar and wind power have taken off thanks to the state's ambitious clean energy goals. But there's another way to generate electricity — by using organic material like agricultural and tree waste. It's known as biomass power, but as Lauren Sommer reports, some say it's not as green as it seems.
Japan's nuclear power crisis is renewing debate over the topic of safety at nuclear power plants. Andrea Kissack talks with two men with very different opinions on the issue: Bill Magavern, head of the Sierra Club California and Ed Morse, Professor of Nuclear Engineering at University of California, Berkeley.
In California, a state agency called CalFire is charged with fighting fire in rural areas. But over the years, the line between rural and urban has become much less clear. Governor Jerry Brown proposed to scale back CalFire and help trim the state's budget, but that proposal may go down in flames.
It's been a harsh winter across the US. Snow has blanketed the Sierra Nevada, where the snowpack is well above normal. Lots of snow means good skiing, but it also means an increased danger of avalanches. Lauren Sommer travels to Lake Tahoe where researchers are trying to understand the inner workings of snow a little bit better.
40 years ago, Stanford psychology professor Phillip Zimbardo's notorious Stanford Prison Experiment demonstrated how good people can do evil things. Now, his "Heroic Imagination Project" takes those lessons to an Oakland high school to see if heroes can also be made.
After a series of high-profile recalls, the FDA says it's reconsidering rules that allow cheese makers to use unpasteurized milk in their products. That could mean big changes in Northern California, which has become a hub of artisanal cheese making.
Solar power is booming in California. Last year, state officials approved an unprecedented amount of new solar energy. But large solar farms and small home rooftop installations have run into challenges. As Lauren Sommer reports, that's why a new sector of solar is emerging — one that benefits from being in the middle.
It probably goes without saying: the dentist's chair isn't the most popular place to visit. But going the dentist may soon be a very different experience. As Lauren Sommer reports, researchers at the University of California San Francisco are developing new technology that may make dentists' drills less common.
