Biologists deliver neutralizing antibodies that protect against HIV infection in mice

ScienceDaily (Nov. 30, 2011) — Over the past year, researchers at the California Institute of Technology (Caltech), and around the world, have been studying a group of potent antibodies that have the ability to neutralize HIV in the lab; their hope is that they may learn how to create a vaccine that makes antibodies with similar properties. Now, biologists at Caltech led by Nobel Laureate David Baltimore, president emeritus and Robert Andrews Millikan Professor of Biology, have taken one step closer...

Galaxies are the ultimate recyclers, NASA's Hubble confirms

ScienceDaily (Nov. 17, 2011) — Galaxies learned to "go green" early in the history of the universe, continuously recycling immense volumes of hydrogen gas and heavy elements to build successive generations of stars stretching over billions of years.This ongoing recycling keeps galaxies from emptying their "fuel tanks" and therefore stretches out their star-forming epoch to over 10 billion years. However, galaxies that ignite a rapid firestorm of star birth can blow away their remaining fuel, essentially...

Training in 'concrete thinking' can be self-help treatment for depression, study suggests

ScienceDaily (Nov. 17, 2011) — New research provides the first evidence that depression can be treated by only targeting an individual's style of thinking through repeated mental exercises in an approach called cognitive bias modification.The study suggests an innovative psychological treatment called 'concreteness training' can reduce depression in just two months and could work as a self-help therapy for depression in primary care.Led by the University of Exeter and funded by the Medical Research...

Great Plains river basins threatened by pumping of aquifers

ScienceDaily (Nov. 18, 2011) — Suitable habitat for native fishes in many Great Plains streams has been significantly reduced by the pumping of groundwater from the High Plains aquifer -- and scientists analyzing the water loss say ecological futures for these fishes are "bleak."Results of their study have been published in the journal Ecohydrology.Unlike alluvial aquifers, which can be replenished seasonally with rain and snow, these regional aquifers were filled by melting glaciers during the...

Old drugs find new target for treating brain tumor

ScienceDaily (Nov. 18, 2011) — Scientists at the University of California, San Diego School of Medicine and UC San Diego Moores Cancer Center, in collaboration with colleagues in Boston and South Korea, say they have identified a novel gene mutation that causes at least one form of glioblastoma (GBM), the most common type of malignant brain tumor.The findings are reported in the online edition of the journal Cancer Research.Perhaps more importantly, the researchers found that two drugs already being...

More accurate tropical cyclone prediction model developed

ScienceDaily (Nov. 18, 2011) — Researchers at the Naval Research Laboratory Marine Meteorology Division (MMD), Monterey, Calif., have developed the Coupled Ocean/Atmosphere Mesoscale Prediction System Tropical Cyclone (COAMPS-TC™) model, achieving a significant research milestone in predictions of tropical cyclone intensity and structure.While the predictions of the paths or tracks of hurricanes, more generally referred to as tropical cyclones (TC), have steadily improved over the last few decades,...
