How rules of physics in quantum world change when applied to classical world (July 3, 2010) -- Researchers have discovered a potentially important piece of the quantum/classical puzzle -- learning how the rules of physics in the quantum world (think smaller than microscopic) change when applied to the classical world (think every day items, like cars and trees). ... > full story
Childhood malnutrition could weaken brain function in elderly (July 3, 2010) -- Malnutrition early in life appears to diminish brain function in older adulthood, according to a new study that has implications for many poor, developing nations. ... > full story
Excess nitrogen favors plants that respond poorly to rising CO<sub>2</sub> (July 3, 2010) -- As atmospheric carbon dioxide levels rise, so does the pressure on the plant kingdom. The hope among policymakers, scientists and concerned citizens is that plants will absorb some of the extra CO2 and mitigate the impacts of climate change. For a few decades now, researchers have hypothesized about one major roadblock: nitrogen. ... > full story
Scientists uncover novel role for DNA repair protein linked to cancer (July 3, 2010) -- Researchers report that DNA polymerase theta, or PolQ, promotes an inaccurate repair process, which can ultimately cause mutations, cell death or cancer. ... > full story
Volcanic ash research shows how plumes end up in the jet stream (July 3, 2010) -- A volcanologist has shown how the jet stream -- the area in the atmosphere that pilots prefer to fly in -- also seems to be the area most likely to be impacted by plumes from volcanic ash. ... > full story
People with depression eat more chocolate, a mood food (July 3, 2010) -- Researchers have found that women and men eat more chocolate as depressive symptoms increase, suggesting an association between mood and chocolate. ... > full story
Scientists find direct line from development to growth (July 3, 2010) -- It may seem intuitive that growth and development somehow go together so that plants and animals end up with the right number of cells in all the right places. But it is only now that scientists have gotten some of the first insights into how this critical coordination actually works in a plant. ... > full story
Subtle mutations in immune gene may increase risk for asthma (July 3, 2010) -- A gene that encodes a protein responsible for determining whether certain immune cells live or die shows subtle differences in some people with asthma, researchers report. ... > full story
Cell phone microscope poised to begin trials in Africa (July 3, 2010) -- Engineers have developed a functioning prototype of a cell phone microscope for telemedicine. The lensless imaging platform behind the cell phone microscope is nearing readiness for real world trials, after receiving prestigious awards in the past month from the Bill and Melinda Gates Foundation, National Geographic and the National Science Foundation. ... > full story
Cellular and molecular events that restrict HIV transmission identified (July 3, 2010) -- Researchers have identified two molecules that when activated by drugs, can inhibit a number of specific aspects of HIV transmission. These findings may lead to therapies that target mucosal HIV transmission. ... > full story
Molecular prosthesis against gout (July 3, 2010) -- Researchers in Switzerland have devised a new method for preventing and permanently eradicating the cause of gout. It involves implanting a biological network that regulates the uric acid levels autonomously. ... > full story
Looking back key to moving forward: Counterfactual reflection is critical to institutional prosperity, study finds (July 3, 2010) -- Despite modest economic gains, gloomy unemployment numbers and low workplace morale still loom large within corporate America. ... > full story
