The NASA spacecraft is designed to answer a 42-year-old mystery about lunar dust, but it's also snapping photos along the way.
U.S. could make substantial reductions in greenhouse gas emissions by stopping methane leaks from natural gas pipelines, says a new Stanford study.
State officials are trying to do damage control to help endangered salmon during the drought, but helping some fish could hurt others.
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.
California has had its share of "megadroughts." This isn't one of them...yet.
Among the first and hardest-hit by the drought are ranchers and farmers who are now faced with some tough choices. The decisions they'll soon be making will have a ripple effect from the farm to the table.
Even with some recent rain, California’s drought grinds on, and health officials say 17 communities could run out of water within the next four months – or sooner. One of those, an hour north of Los Angeles, is the town of Lake of the Woods, perched above the Tejon Pass.
In Southern California there’s no imminent threat of water rationing. In fact, the region may be in a position to help other water-starved parts of the state.
California's deepening drought could have an effect on the electricity supply. Hydropower usually accounts for about 14 percent of the state's power, but with low reservoir levels, officials are preparing for it to be less.
And the clock is ticking toward April 1, when snow accumulation usually peaks.
It finally rained and snowed in parts of Northern California, but we are still deep in a drought. Now, 17 communities in California are at risk of running out of water within 60 to 100 days.
As California's drought gets worse, farmers and conservationists are teaming up to create temporary wetlands for birds migrating on the Pacific Flyway.
Tens of thousands of people are expected to descend on Half Moon Bay to watch the big wave surf contest, but the beach and cliffs are off-limits to spectators. If you want to watch the competition, your options are on TV, online or at a festival near the beach.
John Dobson, the co-founder of San Francisco Sidewalk Astronomers and the inventor of a telescope that people can build themselves, died on January 15 in Burbank. He was 98. For decades, Dobson introduced the public to the sky, setting up telescopes in cities and parks and inviting passers-by to take a look into space. And […]
David Perlman, the San Francisco Chronicle's science editor has been on the job for more than a half-century. He covered the launch of the space age and the unfolding of the computer age, and his career has spanned Pluto's entire life as a planet, from its discovery in 1930 to its demotion to sub-planet.
