New data provide the strongest evidence to date that the world's biggest mud volcano, which killed 13 people in 2006 and so far has displaced 30,000 people in East Java, Indonesia, was not caused by an earthquake, according to an international scientific team that includes researchers from Durham University and the UC Berkeley.
Pyrethroid pesticides were supposed to be a benign replacement for organophosphate use around the home, but UC Berkeley studies show that these insecticdes are showing up at toxic levels in storm runoff and even in the effluent from sewage treatment plants. While the levels are not high enough to harm fish, they may be enough to kill the mayfly, caddisfly and stonefly larvae upon which the fish feed.
UC Berkeley scientists have created smart nanoprobes that may one day be used in the battle against cancer to selectively seek out and destroy tumor cells, as well as report back on the mission's status.
Bioengineers from the UC Berkeley and Stanford University are ramping up efforts to characterize the thousands of control elements critical to the engineering of microbes so that eventually, researchers can mix and match these "DNA parts" in synthetic organisms to produce new drugs, fuels or chemicals.
The Lawrence Hall of Science is hosting a 50th-anniversary exhibit on the laser, Jan. 23-25, highlighted by a free public talk on Jan. 25 by Nobel Laureate Charles Townes, who conceived the idea of a laser in the 1950s.
Marcia Linn, a University of California, Berkeley, professor of education known for exploring the teaching and learning of science and their connection to gender, is offering proof once again that girls' math abilities are just as good as boys'.
Once trees expand their range into the Arctic, their higher transpiration rate could well pump enough extra water into the atmosphere to warm the climate over the entire Arctic region, with positive feedback speeding the melting of sea ice.
