| Tibetans developed genes to help them adapt to life at high elevations Posted: 15 May 2010 02:00 PM PDT Researchers have long wondered why the people of the Tibetan Highlands can live at elevations that cause some humans to become life-threateningly ill -- and a new study answers that mystery, in part, by showing that through thousands of years of natural selection, those hardy inhabitants of south-central Asia evolved 10 unique oxygen-processing genes that help them live in higher climes. |
| Faster Salmonella detection now possible with new technique Posted: 15 May 2010 02:00 PM PDT A professor of food science and human nutrition wants to replace the current system of Salmonella detection with a new approach that can provide DNA sequencing-like results in hours rather than days. |
| Posted: 15 May 2010 02:00 PM PDT Scientists have developed a 3D test for malignant melanoma that can identify problems not easily spotted in a standard two-dimensional view of the pattern on the skin. |
| New energy-efficient insulation for electrical wires Posted: 15 May 2010 02:00 PM PDT Engineers in the UK are working to develop prototype insulation systems that could lead to new high-efficiency electrical generators. |
| Virtual humans appear to influence ethical decisions in gender-specific ways Posted: 15 May 2010 02:00 PM PDT Virtual humans are increasingly taking on roles that were once reserved for real humans. A study found that the decisions of men were strongly affected by presentational aspects of the simulated woman, while women's decisions were not. |
| Spitting cobras track first, predict later Posted: 15 May 2010 08:00 AM PDT Spitting cobras spray venom in the eyes of their victims with remarkable accuracy, but how do they achieve this accuracy when they cannot steer the jet of venom? Researchers have found that cobras initially track their prey's movements, but at the moment when they spit, they predict where the victim's eyes will be 200 meters in the future and aim there. |
| Research may help patients with intestinal failure, other malabsorptive disorders Posted: 15 May 2010 08:00 AM PDT New treatments for intestinal failure and other intestinal absorption disorders are a step closer to the patients who need them after a discovery showing that butyrate, a short-chain fatty acid, helps intestine grow and become more functional. |
| Revealing the metabolic activity of microbial communities: New method for tracing carbon flux Posted: 15 May 2010 08:00 AM PDT Microbial communities are performing important functions all around us -- from the earth in our flowerpots to the human gut. Now researchers have developed a method for studying the metabolic functions of microbial communities in detail. It is now possible for the first time, thanks to a new algorithm, to use the incorporation of stable carbon isotopes into proteins to investigate natural remineralization processes in much greater detail, to identify relevant key species and to study the way they interact in complex decomposition processes. |
| Clue to switch of bladder cancer from locally contained to invasive Posted: 15 May 2010 08:00 AM PDT Bladder cancer often becomes aggressive and spreads in patients despite treatment, but now researchers have identified a protein they believe is involved in pushing tumors to become invasive -- and deadly. |
| Strategies for increasing carbon stored in forests and wood Posted: 15 May 2010 08:00 AM PDT While the US and other world leaders consider options for offsetting carbon emissions, it is important to take into account the role forests play in the global carbon cycle, say scientists in a new research paper. Currently, the carbon stored in forests and harvested wood products offsets 12-19 percent of US fossil fuel emissions -- growth primarily the result of recovery from the large scale harvesting that occurred around 100 years ago. |
| New research reveals Hurricane Katrina's impact on ecological and human health Posted: 15 May 2010 08:00 AM PDT Scientists studying the environmental impact of Hurricane Katrina on the Gulf Coast of Louisiana and the city of New Orleans have revealed the ecological impact and human health risks from exposure to chemical contaminants. The findings demonstrate how Hurricane Katrina caused significant ecological damage by altering coastal chemistry and habitat. |
