BERKELEY — UC Berkeley biologist Anthony Barnosky’s 2012 Nature paper warning of an impending tipping point in Earth’s climate resonated with California Governor Jerry Brown, who called Barnosky out of the blue to ask his help in spreading the message to politicians and policy makers. As reported in the July 24 issue of Nature, Barnosky, a professor of integrative biology and member […]
UC Berkeley researchers are developing ultra-sensitive bomb detectors using tiny laser sensors. Experiments showed that the nanoscale plasmon sensors could detect airborne explosives at concentrations below one part per billion, a result that is much more sensitive than published results to date for other optical sensors.
Using the world's largest laser at Lawrence Livermore National Laboratory's National Ignition Facility, scientists including UC Berkeley's Ray Jeanloz have created the extreme temperatures and pressures found inside planets like Jupiter. These experiments are vital for understanding how dirty, carbon-rich planets, including newly discovered exoplanets, formed.
Heino Nitsche, professor of chemistry and LBNL senior scientist, passed away unexpectedly at home July 14. A native of Germany, Nitsche was a nuclear chemist who focused on the synthesis and chemistry of superheavy elements. He was part of a team that confirmed superheavy elements 114 and 117, so far unnamed
UC Berkeley seismologists Doug Dreger and Avinash Nayak looked at seismic records of quakes that preceded the formation of a massive sinkhole near Bayou Corne, La., in 2012, and determined that they came from strong underground gas discharges, which may have caused the collapse of a salt dome now flooded with water.
Tens of thousands of years ago, the common ancestors of Han Chinese and Tibetans interbred with a mysterious human-like group known as Denisovans and picked up a unique variant of a gene for hemoglobin regulation that later helped them adapt to a low-oxygen environment on the high Tibetan plateau, reports UC Berkeley professor of integrative biology Rasmus Nielsen.
Grad student Jingyi Jesscia Li, plant and microbial biology professor Steve Brenner and colleagues compared the genes activated during development in the early fruit fly and nematode (C. elegans) and found them to be surprisingly similar. Fruit flies actually use these genes twice, once during larval development and again during metamorphosis. The research is part of the modENCODE project.
Robert Dudley, an evolutionary physiologist and professor of integrative biology, discusses his new book, "The Drunken Monkey, Why we drink and abuse alcohol" (UC Press 2014). Dudley talks about his motivations for writing the book, the evidence that our attraction to alcohol is an evolutionary adaptation, and what this means for efforts to prevent alcohol abuse.
Imagine feeling a slimy jellyfish, a prickly cactus or map directions on your iPad display. Virtual textured touchscreens are where tactile technology is headed. New research has found that people are faster at navigating tactile technology when using both hands and several fingers. Moreover, blind people in the study outmaneuvered their sighted counterparts.
Don DePaolo, professor of earth and planetary sciences and LBNL researcher, received the Harry Hess Medal of the American Geophysical Union for groundbreaking research on the geochemical structure of Earth’s mantle, the isotopic and trace element chemistry of oceanic volcanoes, and the origin of granitic igneous rocks.
Richard Allen, professor of earth and planetary sciences and director of the Berkeley Seismological Laboratory, is taking 10 students on a research cruise to study the Cascadia subduction zone, a major source of Northwest coast earthquakes. The students hope to send daily video blogs about their experiences and the science of subduction quakes @BerkeleySeismo.
BERKELEY — Three young UC Berkeley researchers have been selected as 2014 Pew scholars, The Pew Charitable Trusts announced this week. The researchers are: Elçin Ünal, assistant professor of molecular and cell biology, who was selected as one of 22 2014 Pew Scholars in the Biomedical Sciences. The award supports promising early-career scientists in the health sciences, particularly young researchers […]
UC Berkeley and Berkeley Lab physicists have detected what is believed to be the smallest force ever measured: approximately 42 yoctonewtons. A yoctonewton is one septillionth of a newton and there are approximately 3 x 10^23 yoctonewtons in one ounce of force. They employed a combination of lasers to push and probe a cloud of ultracold atoms.
