The past year has been marked by a series of moral transgressions by powerful figures in political, business and celebrity circles. New research from the Kellogg School of Management at Northwestern University explores why powerful people - many of whom take a moral high ground - don't practice what they preach. http://www.physorg.com/news181311436.html Medicine & Health Tue, 29 Dec 2009 12:18:06 EST news181311436 (PhysOrg.com) -- Scientists at the University of East Anglia, Pacific Northwest National Laboratory, and Pennsylvania State University have demonstrated for the first time the mechanism by which some bacteria can transfer electrons across a membrane to the cell exterior, allowing them to "breathe" metals. These iron-respiring bacteria link the cycling of iron and carbon in subsurface and surface sediments and can catalyze the immobilization of subsurface contaminants such as uranium. http://www.physorg.com/news181309967.html Chemistry Tue, 29 Dec 2009 11:53:48 EST news181309967 (PhysOrg.com) -- Shareholders of Nike, Gatorade and other Tiger Woods sponsors lost a collective $5 to $12 billion in the wake of the scandal involving his extramarital affairs, according to a new study by researchers at the University of California, Davis. http://www.physorg.com/news181305893.html Other Sciences Tue, 29 Dec 2009 10:45:41 EST news181305893 Experts are studying the first Mayan hieroglyphic script dealing with the life of a high priest, his blood sacrifices and acts of penance, Mexico's National Institute of Anthropology and History (INAH) said. http://www.physorg.com/news181288215.html Other Sciences Tue, 29 Dec 2009 05:55:46 EST news181288215 US researchers have found an antibody that hunts down prostate cancer cells in mice and can destroy the killer disease even in an advanced stage, a study showed Monday. http://www.physorg.com/news181245375.html Medicine & Health Mon, 28 Dec 2009 17:56:53 EST news181245375 (PhysOrg.com) -- Researchers from the Northwestern University Feinberg School of Medicine have identified mutations in the gene for TRPV4 that cause two related degenerative motor nerve disorders, scapuloperoneal spinal muscular atrophy (SPSMA) and hereditary motor and sensory neuropathy type IIC (CMT2C). http://www.physorg.com/news181242749.html Medicine & Health Mon, 28 Dec 2009 17:13:48 EST news181242749 By combining a research technique that dates back 136 years with modern molecular genetics, a Johns Hopkins neuroscientist has been able to see how a mammal's brain shrewdly revisits and reuses the same molecular cues to control the complex design of its circuits. http://www.physorg.com/news181241784.html Medicine & Health Mon, 28 Dec 2009 16:57:14 EST news181241784 (PhysOrg.com) -- Moving pictures are more suitable to interpret the mood of a person than a static photograph. http://www.physorg.com/news181240600.html Medicine & Health Mon, 28 Dec 2009 16:37:32 EST news181240600 (PhysOrg.com) -- The timing of molar emergence and its relation to growth and reproduction in apes is being reported by two scientists at Arizona State University's Institute of Human Origins in the Dec. 28 online early edition of the Proceedings of the National Academy of Sciences (PNAS). http://www.physorg.com/news181237351.html Biology Mon, 28 Dec 2009 16:20:02 EST news181237351 Scientists have created what appears to be a schizophrenic mouse by reducing the inhibition of brain cells involved in complex reasoning and decisions about appropriate social behavior. http://www.physorg.com/news181238493.html Medicine & Health Mon, 28 Dec 2009 16:02:24 EST news181238493 (AP) -- A Nevada couple letting their SUV's navigation system guide them through the high desert of Eastern Oregon got stuck in snow for three days when the GPS unit sent them down a remote forest road. http://www.physorg.com/news181235682.html Technology Mon, 28 Dec 2009 15:50:05 EST news181235682 (AP) -- They're not your grandpa's hearing aids.

Three Penn State researchers have shown that certain combinations of elemental atoms have electronic signatures that mimic the electronic signatures of other elements. According to the team's leader A. Welford Castleman Jr., Eberly Distinguished Chair in Science and Evan Pugh Professor in the Departments of Chemistry and Physics, "the findings could lead to much cheaper materials for widespread applications such as new sources of energy, methods of pollution abatement, and catalysts on which industrial nations depend heavily for chemical processing." http://www.physorg.com/news181225307.html Physics Mon, 28 Dec 2009 15:00:12 EST news181225307 Just like teenagers at a prom, proteins are tended by chaperones whose job it is to prevent unwanted interactions among immature clients.
