Naegleria genome sheds light on transition from prokaryotes to eukaryotes In the long evolutionary road from bacteria to humans, a major milestone occurred some 1.5 billion years ago when microbes started building closets for all their stuff, storing DNA inside a nucleus, for example, or cramming all the energy machinery inside mitochondria. Scientists have now sequenced the genome of a weird, single-celled organism called Naegleria gruberi that is telling biologists about that transition...

Atrazine, one of the world's most widely used pesticides, wreaks havoc with the sex lives of adult male frogs, emasculating three-quarters of them and turning one in 10 into females, according to a new study by University of California, Berkeley, biologists. The 75 percent that are chemically castrated are essentially "dead" because of their inability to reproduce in the wild, reports UC Berkeley's Tyrone B. Hayes, professor of integrative biology. "These male frogs are missing testosterone...

The National Science Foundation (NSF) has awarded $24.5 million to researchers at the University of California, Berkeley, to head an ambitious, multi-institutional center that could one day lead to a million-fold reduction in power consumption by electronics. The researchers said such a dramatic increase in energy efficiency could allow the digital revolution to continue well beyond the limits that would otherwise be imposed by its growing demand for energy, and allow portable applications...

Findings suggest that a biphasic sleep schedule not only refreshes the mind, but can make you smarter If you see a student dozing in the library or a co-worker catching 40 winks in her cubicle, don't roll your eyes. New research from the University of California, Berkeley, shows that an hour's nap can dramatically boost and restore your brain power. Indeed, the findings suggest that a biphasic sleep schedule not only refreshes the mind, but can make you smarter. Conversely, the more hours we...

A picture is worth a thousand words, or so University of California, Berkeley, astronomer Paul Kalas found out when he published a Hubble Space Telescope image of a Jupiter-sized planet orbiting the star Fomalhaut. Since it appeared in the journal Science in November 2008, "the image of Fomalhaut, its visually striking belt of comet dust and its planet has become an iconic image of a planetary system," said Kalas, an adjunct associate professor of astronomy at UC Berkeley. National Geographic...

Scientists measure interference between matter waves separated by 0.1 mm While airplane and rocket experiments have proved that gravity makes clocks tick more slowly "“ a central prediction of Albert Einstein's general theory of relativity "“ a new experiment in an atom interferometer measures this slowdown 10,000 times more accurately than before, and finds it to be exactly what Einstein predicted. The result shows once again how well Einstein's theory describes the real world,...

In research that gives literal meaning to the term "power suit," University of California, Berkeley, engineers have created energy-scavenging nanofibers that could one day be woven into clothing and textiles. These nano-sized generators have "piezoelectric" properties that allow them to convert into electricity the energy created through mechanical stress, stretches and twists. "This technology could eventually lead to wearable 'smart clothes' that can power hand-held electronics through...

Swiss, California and Spanish researchers have found that particulates from auto exhaust can lead to the thickening of artery walls, possibly increasing chances of a heart attack and stroke. In a study reported this week in the journal PLoS ONE, the researchers used ultrasound to measure the carotid artery wall thickness of 1,483 people who lived near freeways in the Los Angeles area. The researchers took these measurements every six months for approximately three years, and correlated them...

Pyrethroids, among the most widely-used home pesticides, are winding up in California rivers at levels toxic to some stream-dwellers, possibly endangering the food supply of fish and other aquatic animals, according to a new study by researchers at the University of California, Berkeley, and Southern Illinois University (SIU). Pyrethroid insecticides, commonly used in California to kill ants and other insect pests around the home, have been found in street runoff and in the outflow from...

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...
