Night light pollution affect songbirds' mating life, research suggests (September 18, 2010) -- In today's increasingly urbanized world, the lights in many places are always on, and according to a new study, that's having a real impact on the mating life of forest-breeding songbirds. ... > full story
Alzheimer's drug boosts perceptual learning in healthy adults (September 18, 2010) -- Scientists have found that healthy adults showed greater improvement from practice on a motion direction discrimination task when they took donepezil, a commonly prescribed Alzheimer's drug, compared with when they took a placebo. The research is helping neuroscientists better understand perceptual learning in healthy adults. ... > full story
Quantum tornado in the electron beam: Manipulating materials with rotating quantum particles (September 18, 2010) -- Researchers have succeeded in producing what are known as electron vortex beams: rotating electron beams, which make it possible to investigate the magnetic properties of materials. In the future, it may even be possible to manipulate the tiniest components in a targeted manner and set them in rotation. ... > full story
Tick tock: Rods help set internal clocks, biologist says (September 18, 2010) -- Rod cells -- one of three kinds of exquisitely photosensitive cells found in the retina of the eye -- are surprisingly found to be the only ones responsible for setting our internal "clocks" in low light. ... > full story
Synthetic fuels research aims to reduce oil dependence (September 18, 2010) -- Researchers have developed a facility aimed at learning precisely how coal and biomass are broken down in reactors called gasifiers as part of a project to strengthen the scientific foundations of the synthetic fuel economy. ... > full story
Overprotective parents may impact heart anxiety in adults with congenital heart conditions (September 18, 2010) -- Adults with congenital heart disease are more likely to suffer heart-focused anxiety -- a fear of heart-related symptoms and sensations -- if their parents were overprotective during their childhood and adolescence. ... > full story
Fish schools and krill swarms take on common shape (September 18, 2010) -- When fish or tiny, shrimp-like krill get together, it appears they follow the same set of "rules." According to a new study, shoals of fish and swarms of krill hang out in groups that take on the same overall shape; it's not a simple sphere, a cylinder, or ovoid, but something more akin to an irregular crystal, the researchers say. ... > full story
Promising techniques for extending the life of an organ transplant developed (September 18, 2010) -- Experts have revealed exciting new scientific developments for people with an organ transplant, intended to help prevent rejection of the new organ and extend its life. These advances in protein therapeutics and cell therapy could provide a future solution to some of the challenges surrounding organ transplantation. ... > full story
NASA uses new method to estimate Earth mass movements (September 18, 2010) -- NASA and European researchers have conducted a novel study to simultaneously measure, for the first time, trends in how water is transported across Earth's surface and how the solid Earth responds to the retreat of glaciers following the last major Ice Age, including the shifting of Earth's center of mass. ... > full story
Drug combination may treat traumatic brain injury (September 18, 2010) -- Currently, there are no drugs available to treat TBI: a variety of single drugs have failed clinical trials, suggesting a possible role for drug combinations. Testing this hypothesis in an animal model, researchers tested five drugs in various combinations. Their observations suggest a potentially valuable role for minocycline plus N-acetylcysteine to treat TBI. ... > full story
U.S. tsunami detection improves, but coastal areas still vulnerable, report finds (September 18, 2010) -- The nation's ability to detect and forecast tsunamis has improved since the 2004 Indian Ocean tsunami, but current efforts are still not sufficient to meet challenges posed by tsunamis generated near land that leave little time for warning, says a new report. ... > full story
Proposal by WHO to eliminate AIDS in South Africa is flawed, model shows (September 18, 2010) -- The World Health Organization has proposed a new strategy for combating the AIDS epidemic in South Africa. It is a strategy that is seriously flawed, say researchers. ... > full story
