Los Angeles -- Bill Nye, known on TV as "the Science Guy," collapsed onstage during an appearance at the University of California, witnesses said.
Nye, 54, got back up quickly and resumed his presentation, the Los Angeles Times reported Wednesday.
USC senior Tristan Camacho said Nye was striding toward the podium Tuesday night when he went down in mid-sentence.
"Then after about 10 seconds, he popped back up with much gusto and asked everybody how long he was out for and went on with a story about how a similar thing happened to him that morning," she said.

Berkeley, Calif. -- Jet lag might make you more than just groggy and dazed, U.S. researchers say -- it might even make you stupid.
Researchers at the University of California, Berkeley, said hamsters suffering extreme, chronic jet lag had about half the normal rate of new neuron birth in one part of the brain and showed deficits in learning and memory, ScienceNews.org reported Tuesday.
The scientists subjected hamsters to simulated jet lag by advancing their day and night schedule by 6 hours every three days for nearly a month, "like a flight from New York to Paris every three days," study coauthor Erin Gibson said.

Berkeley, Calif. -- The North American continent is not one single, solid slab, researchers say, but rather a layer cake of old and new material dating back 3 billion years.
Seismologists at the University of California, Berkeley, say a layer of 3-billion-year-old rock sits on top of much newer material less than 1 billion years old, ScienceDaily.com reported Thursday.
"This is exciting because it is still a mystery how continents grow," study co-author Barbara Romanowicz, UC Berkeley professor of earth and planetary science, said.

Lindsay Lohan’s mother Dina thinks her judge was too harsh. She defended Lindsay, during an interview with Matt Lauer on NBC's ‘Today’ show, asserting her 24 year-old daughter did not deserve jail time – “not for this particular offense.”

Berkely, Calif. -- Scientists say the gene sequence of sponges, the simplest and most ancient of animals, could provide clues to how multi-cell animals -- and cancer -- developed.
University of California, Berkeley, researchers say the common ancestor of sponges and humans -- in fact of all animals -- lived 600 million years ago, and a sponge-like creature may have been the first organism with more than one cell type and the ability to develop by repeatedly dividing the one cell created by the merger of egg and sperm cells, a university release said Wednesday.
"Our hypothesis is that multicellularity and cancer are two sides of the same coin," Daniel Rokhsar, a professor of molecular and cell biology at UC Berkeley said.

Irvine, Calif. -- Your talents and abilities could someday be revealed through a brain scan, possibly guiding your career choices, U.S. scientists say.
Neuroscientists at the University of California, Irvine, scanned 6,000 volunteers in an effort to build a brain "map" that could match particular areas to particular skills and knowledge, The Daily Telegraph reported Thursday.
While being scanned, volunteers performed cognitive tests to see if there was a connection between brain and aptitude, the newspaper said.

Irvine, Calif. -- The SETI Institute, listening to the cosmos for signs of signals from alien civilizations, may be monitoring the wrong "channels," a U.S. astrophysicist says.
Gregory Benford of the University of California, Irvine, says such a civilization wanting to announce it presence would transmit "cost-optimized" narrowly focused signals, not the continuous omni-directional signals the SETI program has been scanning for, a university release said Wednesday.
"This approach is more like Twitter and less like War and Peace, " James Benford, Gregory Benford's twin and fellow physicist, says.
Such short, targeted blips, dubbed Benford beacons, should be the targets of SETI efforts, a growing number of scientists say.

Santa Barbara, Calif. -- U.S. scientists report a major advance in synthesizing photovoltaic organic polymers that convert sunlight into electricity in non-silicon-based solar cells.
University of California-Santa Barbara Professor Guillermo Bazan and colleagues said they've been able to reduce reaction time by 99 percent, while more than tripling the average molecular weight of the polymers.
The scientists said the reduced reaction time effectively cuts production time for the organic polymers by nearly 50 percent, since reaction time and purification time are approximately equal in the production process, in both laboratory and commercial environments.

Riverside, Calif. -- U.S. scientists say they've created a genetic map of the cowpea -- a protein-rich legume vital in the diet of such places as South America, Africa and Asia.
Although cowpeas and other grain legumes complement corn- and rice-based diets, breeding new cowpea varieties with desirable traits is a time-consuming and laborious process that can take a decade from concept to release, scientists said.
But -Riverside scientists say they've developed a high-density "consensus genetic map" of the cowpea that significantly accelerates the production of new varieties of not only cowpeas, but also other legumes, particularly soybeans and the common bean -- both near relatives of cowpeas.
