Broken bones and broken spirits. Hurting bodies and hurt feelings. We often use the same words to describe physical and mental pain. Over-the-counter pain relieving drugs have long been used to alleviate physical pain, while a host of other medications have been employed in the treatment of depression and anxiety. But is it possible that a common painkiller could serve double duty, easing not just the physical pains of sore joints and headaches, but also the pain of social rejection? A research team led by psychologist C. Nathan DeWall of the University of Kentucky College of Arts and Sciences Department of Psychology has uncovered evidence indicating that acetaminophen (the active ingredient in Tylenol) may blunt social pain. http://www.physorg.com/news180723689.html Medicine & Health Tue, 22 Dec 2009 17:05:56 EST news180723689 (PhysOrg.com) -- At first glance, a dog chasing its tail seems a harmless, if fruitless, pursuit. But for many dogs and their owners, the habit has a dark side, one that means endless hours and energy spent on the same task, to the exclusion of nearly all others. The cause, a type of compulsive disorder, can result in lack of sleep and even physical injury. http://www.physorg.com/news180722905.html Biology Tue, 22 Dec 2009 17:00:02 EST news180722905 Using a technique that provides detailed images of nanoscale structures, researchers at the University of Michigan and Detroit's Henry Ford Hospital have discovered changes in the collagen component of bone that directly relate to bone health. http://www.physorg.com/news180721167.html Medicine & Health Tue, 22 Dec 2009 16:50:05 EST news180721167 (PhysOrg.com) -- Microscopic ridges contouring the surface of flower petals might play a role in flashing that come-hither look pollinating insects can't resist.

Evidence that the taste system influences olfactory perception, however, has been vanishingly rare -until now. In a novel study this week in Nature Neuroscience, Brandeis researchers report just such an influence. http://www.physorg.com/news180716870.html Medicine & Health Tue, 22 Dec 2009 16:10:03 EST news180716870 From their humble beginnings as offshoots of the ordinary electric light bulb, particle accelerators have evolved in surprising directions. Among the most productive and promising developments have been light sources, first in the form of electron storage rings -- of which the Advanced Light Source is the world's premier source of soft x-rays -- and increasingly as versatile and sophisticated free electron lasers, the next generation of light sources now being studied at Berkeley Lab. http://www.physorg.com/news180718811.html Physics Tue, 22 Dec 2009 15:47:11 EST news180718811 (AP) -- A federal appeals court ordered Microsoft Corp. to stop selling its Word program in January and pay a Canadian software company $290 million for violating a patent, upholding the judgment of a lower court. http://www.physorg.com/news180717012.html Technology Tue, 22 Dec 2009 15:40:49 EST news180717012 (PhysOrg.com) -- Nearly 10 years after the discovery that birds make a hormone that suppresses reproduction, University of California, Berkeley, neuroscientists have established that humans make it too, opening the door to development of a new class of contraceptive and possible treatments for cancer or other diseases. http://www.physorg.com/news180716736.html Medicine & Health Tue, 22 Dec 2009 15:06:24 EST news180716736 Sandia National Laboratories scientists have developed tiny glitter-sized photovoltaic cells that could revolutionize the way solar energy is collected and used. http://www.physorg.com/news180713660.html Technology Tue, 22 Dec 2009 14:14:56 EST news180713660 A team of researchers working in a high containment laboratory at the Centers for Disease Control and Prevention in Atlanta, GA, have solved a fundamental mystery about smallpox that has puzzled scientists long after the natural disease was eradicated by vaccination: they know how it kills us. http://www.physorg.com/news180712105.html Biology Tue, 22 Dec 2009 14:10:18 EST news180712105 More than a hundred years after its discovery, the limbs and vertebrae of a fossil have been pulled off the shelf at the American Museum of Natural History to revise the view of early carnivore lifestyles. Carnivores -currently a diverse group of mostly meat-eating mammals like bears, cats, raccoons, seals, and hyenas -had been considered arboreal in their early evolutionary history. But now that the skeleton of 'Miacis' uintensis has been unpacked from its matrix of sandstone, it is clear that some early carnivores were built to walk on the ground at least part of the time. The new research is published this month in the Journal of Vertebrate Paleontology. http://www.physorg.com/news180713120.html Other Sciences Tue, 22 Dec 2009 14:06:15 EST news180713120 The often feared and sometimes deadly infections caused by MRSA - methicillin-resistant Staphylococcus aureus - are now moving out of hospitals and emerging as an even more virulent strain in community settings and on athletic teams, and raising new concerns about antibiotic resistance. http://www.physorg.com/news180711591.html Medicine & Health Tue, 22 Dec 2009 13:41:08 EST news180711591 Mice without the deoxycytidine kinase (dCK) enzyme have defects in their adaptive immune system, producing very low levels of both T and B lymphocytes, the major players involved in immune response, according to a study by researchers with UCLA's Jonsson Comprehensive Cancer Center. http://www.physorg.com/news180708481.html Medicine & Health Tue, 22 Dec 2009 12:49:18 EST news180708481 Evidence of sophisticated, human behavior has been discovered by Hebrew University of Jerusalem researchers as early as 750,000 years ago - some half a million years earlier than has previously been estimated by archaeologists. http://www.physorg.com/news180707972.html Other Sciences Tue, 22 Dec 2009 12:40:38 EST news180707972 Scratching below the surface of a troublesome sensation that's equal parts tingle-tickle-prickle, sensory scientists from Johns Hopkins have discovered in mice a molecular basis for nonallergic itch. http://www.physorg.com/news180706322.html Medicine & Health Tue, 22 Dec 2009 12:12:39 EST news180706322 Research presented in a paper by Morgan McGuire, assistant professor of computer science at Williams College, and co-author Dr. David Luebke of NVIDIA, introduces a new algorithm to improve computer graphics for video games. http://www.physorg.com/news180705224.html Technology Tue, 22 Dec 2009 12:10:01 EST news180705224 (AP) -- Isahrai Azaria is heading to Austin, Texas, in February, and thanks to Facebook, she already has 40 acquaintances, an invitation to go water tubing, and a line on the best vegetarian lunch place in town. http://www.physorg.com/news180704896.html Technology Tue, 22 Dec 2009 12:00:01 EST news180704896
