UC Davis is acquiring a chunk of meteorite that landed in Northern California last year. The meteorite's age makes it rare and valuable. It contains dust from ancient stars that exploded, the same stuff that eventually formed our solar system.
On a recent weekday afternoon, Al Vogler pulls a 12-foot pole from the back of his pickup truck and trudges to the edge of a 30-acre lot a few blocks from his home on the rugged outskirts of Hesperia, a desert town about 80 miles northeast of Los Angeles.
Martha Rodriguez-Salazar leads the senior choir. (Lisa Aliferis/KQED) In an auditorium tucked behind San Francisco’s Mission Neighborhood Center, a new choir is rehearsing a collection of familiar Spanish songs. The 20 members of the choir didn’t need to audition; no singing experience required here.
Okay, we're a couple of days late on this, but what, you thought we weren't going to post it? Dudes, it's an implosion. Cal State East Bay's Warren Hall was the most seismically vulnerable building in the California State University system. On Saturday, hundreds of spectators gathered to watch it get ...read more
After four years, the Kepler spacecraft has ended its search for habitable planets beyond our solar system. NASA confirmed today that it will no longer attempt to repair two failing, gyroscope-like wheels that kept Kepler steady, meaning that scientists cannot aim the telescope as precisely as they need to.

State regulators are under a court order to set new safe drinking water standards by the end of the month for Chromium-6, a toxic chemical linked to cancer and other health problems. It's also responsible for contaminating the water supply of a now infamous desert town in Southern California. ...read more
Imagine winning the World Series, the lottery and a Nobel Prize all in one day. That's pretty much how scientists and engineers in mission control at NASA's Jet Propulsion Laboratory in Pasadena, Calif., felt one year ago when the one ton, six-wheeled rover named Curiosity landed safely on Mars. Within minutes, ...read more

It's been almost a year since an explosion and fire at the Chevron refinery in Richmond sent plumes of black smoke into the air. Fifteen-thousand people flooded into local hospitals after breathing the fumes, but there was no way to assess what was in the noxious smoke. The air monitoring systems ...read more
Google is testing a project that would bring the internet to people in rural areas and developing nations via high-altitude balloons.
Rampant overfishing in the world’s oceans has led to a dramatic decline in big “predatory” fish populations — the one’s we eat, like tuna and cod – while creating an overabundance of small fish. That’s according to data from a 2011 regression analysis by scientists at the University of British Columbia Fisheries Centre, who used more than 200 marine ecosystem models to show evidence that big fish populations dropped by more than two-thirds over the last century. More than half that decline occurred within the last 40 years. “Overfishing has absolutely had a ‘when cats are away, the mice will play’ effect ...read more
A group of Chinese scientists has come up with a chemical way to turn regular old mouse cells into cells that act just like embryonic stem (ES) cells. This finding has the potential to unleash the awesome potential of ES cells without any of the moral baggage and/or health risks usually associated with them. Since […]
Just about everything that we do in the water makes noise. When we ship goods from country to country, when we explore for oil and gas and minerals, when the military trains with explosives or intense sonar systems — the noise travels. But these man-made noises are making it impossible for sea creatures to communicate with themselves, something that is integral to their survival. Michael Jasny, the director of the Marine Mammal Protection Project for the Natural Resources Defense Council, says we have to quiet down. The Defense Council and other conservation groups reached an agreement with a number of oil ...read more
Spent reactor fuel and other high-level radioactive wastes may be better off in soft rocks than hard ones.
A big wildfire in a mountain range just west of Las Vegas has put at risk the Mt. Charleston blue butterfly, a rare species found in the U.S. The fire is dying down, but it may be weeks before experts can get to the remarkable area where this butterfly lives to see if it made it through. There are few examples of fires wiping a species off the planet. In fact, fires sometimes help rare animals and plants by clearing overgrown habitat. But experts fear that such extinctions could become a consequence of two factors that are making some endangered species ...read more
