Newest Earth science mission could extend the accuracy range of weather forecasts, fine-tune flood forecasts.
Whether it’s a lager or ale, sour or bitter, dark or light, most beer has one thing in common: yeast. KQED Science visits a commercial yeast laboratory and a local brewery to reveal how this key ingredient is a major player in both science history and beer production.
A UCSF researcher explains how public pressure on makeup manufacturers seems to work, and why it's "common sense" to keep plastic dishware out of the microwave.
California overturns a nearly 40-year-old law that made your sofa potentially menacing.
San Francisco cleans up a lot of graffiti every year. In the past, the city has used standard industrial solvents for this task, but now, workers will be cleaning up with non-toxic materials, in an effort to protect people and reduce toxic runoff.
Now that California's legislative session is now over, here's a roundup of the environmental bills that passed -- and a review of some big ones that didn't.

The city of Watsonville has an expensive problem on its hands: toxic algae stirred up from the bottom of Pinto Lake makes the lake poisonous to humans and deadly to birds, fish, and even the otters in Monterey Bay, where the lake water eventually empties into the sea.

Proposition 65 is enforced by, among others, a small and little-known subculture of "private enforcers," and their attorneys who profit from settlements with businesses found to be in violation of the law. Critics call it a "cottage industry;" others say it's an efficient way to protect consumers from toxic chemicals.
Proposition 65 was passed by voters in order to reduce Californian's exposure to toxic chemicals. Now there's an effort in Sacramento to revise the law, amid charges that it's prompted a flood of frivolous lawsuits that make millions of dollars for a select few and cause undue headaches for thousands of California businesses.
Mounting research questions the safety and effectiveness of flame retardants used in consumer products. The chemicals are also used in the foam plastic insulation that improves energy efficiency in buildings. But a measure that just passed a Senate committee this week could pave the way for fire-safe, energy-efficient buildings without causing harm.
Like all mammals, the Neanderthals breast fed their babies. Scientists wanted to know: For how long? A team of researchers say they’ve answered that question by looking at the fossilized tooth of an eight-year old Neanderthal child discovered in a Belgian cave.

Two Bay Area kids are semi-finalists in a national art contest celebrating endangered species. First-grader Hannah Chacko, of San Francisco, turned in this colorful drawing of the endangered San Francisco garter snake. (Perhaps a new t-shirt design for the city’s Sharp Park Golf Course?) Foster City’s Kevin Huo, an ...
