New experiments at the University of California, Berkeley, may one day lead to anti-viral treatments that involve swallowing Salmonella bacteria, effectively using one bug to stop another. Researchers at UC Berkeley's School of Public Health have reprogrammed Salmonella, the same foodborne pathogen that can cause diarrhea, fever and abdominal cramps, to safely transport virus-stopping enzymes into cells without causing disease. Not only did this technique effectively treat mice infected with...

Engineers at the University of California, Berkeley, have found a way to grow nanolasers directly onto a silicon surface, an achievement that could lead to a new class of faster, more efficient microprocessors, as well as to powerful biochemical sensors that use optoelectronic chips. They describe their work in a paper published Feb. 6 in an advanced online issue of the journal Nature Photonics. "Our results impact a broad spectrum of scientific fields, including materials science, transistor...

In a demonstration of "reverse-ecology," biologists at the University of California, Berkeley, have shown that one can determine an organism's adaptive traits by looking first at its genome and checking for variations across a population. The study, published the week of Jan. 31 in the journal Proceedings of the National Academy of Sciences, offers a powerful new tool in evolutionary genetics research, one that could be used to help monitor the effects of climate change and habitat...

By Robert Sanders, UC Berkeley Analysis method can locate satellite galaxies based on the ripples they create in the hydrogen gas Planet X, an often-sought 10th planet, is so far a no-show, but Sukanya Chakrabarti has high hopes for finding what might be called Galaxy X "“ a dwarf galaxy that she predicts orbits our Milky Way Galaxy. Many large galaxies, such as the Milky Way, are thought to have lots of satellite galaxies too dim to see. They are dominated by "dark matter," which...

By Robert Sanders, University of California, Berkeley An unusual galaxy with gas jets could explain how starforming galaxies become red and dead University of California, Berkeley, astronomers may have found the missing link between gas-filled, star-forming galaxies and older, gas-depleted galaxies typically characterized as "red and dead." In a poster to be presented this week at the American Astronomical Society meeting in Seattle, UC Berkeley astronomers report that a long-known...

By Robert Sanders,  UC Berkeley Richard Muller is a guy who thinks spouting fun physics facts will make you the life of the party. And his new book, "The Instant Physicist: An Illustrated Guide," may just convince you he's right. Who knew, for example, that liquor, by law, must be radioactive? Or that you really can get your clothes whiter than white? Or that the earth is travelling through space at a million miles per hour? These are some of the astonishing facts Muller, a professor of...

Researchers at the University of California, Berkeley, have developed a new technique that allows plasmon lasers to operate at room temperature, overcoming a major barrier to practical utilization of the technology. The achievement, described Dec. 19 in an advanced online publication of the journal Nature Materials, is a "major step towards applications" for plasmon lasers, said the research team's principal investigator, Xiang Zhang, UC Berkeley professor of mechanical engineering and...

By Yasmin Anwar, UC Berkeley Older people have a hard time keeping a lid on their feelings, especially when viewing heartbreaking or disgusting scenes in movies and reality shows, psychologists have found. But they're better than their younger counterparts at seeing the positive side of a stressful situation and empathizing with the less fortunate, according to research from the University of California, Berkeley. A team of researchers led by UC Berkeley psychologist Robert Levenson is...

By Yasmin Anwar, University of California, Berkeley Like the mute button on the TV remote control, our brains filter out unwanted noise so we can focus on what we're listening to. But when it comes to following our own speech, a new brain study from the University of California, Berkeley, shows that instead of one homogenous mute button, we have a network of volume settings that can selectively silence and amplify the sounds we make and hear. Neuroscientists from UC Berkeley, UCSF and Johns...

By Carol Ness, UC Berkeley Beauty and truth aren't the first things that come to mind, for most people, when they think about math. Berkeley math professor Edward Frenkel is trying to change that. He tells his classes in multivariable calculus that one of his goals is to unlock the subject's inherent beauty for them, the truth revealed by a mathematical formula. And now, the culture itself is his audience. Frenkel has come out with a 26-minute feature film that aims to achieve that goal...

Einsteinium is a metallic synthetic element with the symbol Es and atomic number 99. It became the seventh transuranic (atomic number higher than 99) element produced. It was named for Albert Einstein. It is an element found within the actinoid series which includes Actinium. Though it has only been produced in small amounts, it has been accurately determined to be silver in coloration. Like all synthetic elements, einsteinium isotopes are highly radioactive and are extremely toxic. Besides...
