(PhysOrg.com) -- Biologists at the University of California, San Diego have identified a key protein that links the morning and evening components of the daily biological clock of plants. http://www.physorg.com/news156087384.html Biology Thu, 12 Mar 2009 14:36:57 EST news156087384 Researchers at the University of California, San Diego School of Medicine have identified a key protein that is required for immune cells called B lymphocytes to divide and replicate themselves. The rapid generation of large numbers of these immune cells is critical to the body's antibody defense mechanism. However, when B cells grow unchecked, it can lead to immune cell cancers such as multiple myeloma or, when they grow to attack the wrong targets, to autoimmune disease. By discovering the role of the CD98hc protein, scientists may find new therapy targets for such diseases. http://www.physorg.com/news155749323.html Medicine & Health Sun, 08 Mar 2009 16:42:28 EST news155749323 Ecologists at the University of California, San Diego, offer a new explanation for an apparently abrupt switch in the kinds in of mammals found along the Malay Peninsula in southeast Asia - from mainland species to island species - in the absence of any geographical barrier. http://www.physorg.com/news155557610.html Biology Fri, 06 Mar 2009 10:30:02 EST news155557610 Using a laser to treat cells in the brain did not significantly reduce stroke disability, according to results of the first major clinical trial of laser therapy presented at the American Stroke Association's International Stroke Conference 2009. http://www.physorg.com/news154618655.html Medicine & Health Mon, 23 Feb 2009 13:39:59 EST news154618655 (PhysOrg.com) -- Small is promising when it comes to illuminating tiny tumors or precisely delivering drugs, but many worry about the safety of nano-scale materials. Now a team of scientists has created miniscule flakes of silicon that glow brightly, last long enough to slowly release cancer drugs, then break down into harmless by-products. http://www.physorg.com/news154538439.html Nanotechnology Sun, 22 Feb 2009 15:21:19 EST news154538439 People voluntarily pick what information they store in short-term memory. Now, using functional magnetic resonance imaging (fMRI), researchers can see just what information people are holding in memory based only on patterns of activity in the brain. http://www.physorg.com/news154466439.html Medicine & Health Sat, 21 Feb 2009 19:21:20 EST news154466439 Working memory (also known as short term memory) is our ability to keep a small amount of information active in our mind. This is useful for information we need to know on-the-fly, such as a phone number or the few items we need to pick up from the grocery store. We hang on to the information for a brief period of time, just long enough to make a phone call or get through the checkout line, and then we forget it forever. http://www.physorg.com/news154349817.html Medicine & Health Fri, 20 Feb 2009 10:57:22 EST news154349817 Researchers from the San Diego Supercomputer Center (SDSC) at the University of California, San Diego, have been awarded a two-year, $450,000 grant from the National Science Foundation to explore new ways for academic researchers to manage extremely large data sets hosted on massive, Internet-based commercial computer clusters, or what have become known as computing "clouds." http://www.physorg.com/news154174486.html Technology Wed, 18 Feb 2009 10:15:38 EST news154174486 (PhysOrg.com) -- Motorists in California equipped with the Apple iPhone can now get personalized traffic information via the "California Traffic Report," the first iPhone application from the University of California, San Diego division of the California Institute for Telecommunications and Information Technology (Calit2). In the first ten days since the app became available through Apple`s App Store on Feb. 7, roughly 2,650 people have downloaded the application, and downloads continue to run at a clip of roughly 250 per day. http://www.physorg.com/news154117861.html Technology Tue, 17 Feb 2009 18:32:09 EST news154117861 Memory loss, cognitive impairment, brain cell degeneration and cell death were prevented or reversed in several animal models after treatment with a naturally occurring protein called brain-derived neurotrophic factor (BDNF). The study by a University of California, San Diego-led team - published in the February 8, 2009 issue of Nature Medicine - shows that BDNF treatment can potentially provide long-lasting protection by slowing, or even stopping the progression of Alzheimer's disease in animal models. http://www.physorg.com/news153323442.html Medicine & Health Sun, 08 Feb 2009 13:51:29 EST news153323442 (PhysOrg.com) -- Engineers at the University of California at San Diego put a single-story house to the test on January 26 via a series of strong simulated earthquake shakes. The first jolt to the wood-stud structure with brick veneer measured a 6.6 magnitude, with the final one coming in at 7.2. http://www.physorg.com/news152814817.html Technology Mon, 02 Feb 2009 16:34:24 EST news152814817 Recent research from the laboratory of Michael Karin, PhD, at the University of California, San Diego School of Medicine - the first researcher to demonstrate a molecular link between inflammation and cancer - has identified two potential targets for the prevention and treatment of colitis-associated cancer (CAC), the most serious complication of inflammatory bowel disease. http://www.physorg.com/news152804231.html Medicine & Health Mon, 02 Feb 2009 13:37:31 EST news152804231 A grid of small arteries at the surface of the brain redirects flow and widens at critical points to restore blood supply to tissue starved of nutrients and oxygen following a stroke, a study published this week has found. http://www.physorg.com/news152561532.html Medicine & Health Fri, 30 Jan 2009 18:12:48 EST news152561532 A team of researchers at the University of California, San Diego (UCSD) and the Moores UCSD Cancer Center have developed a rapid, automated image screening process to distinguish breast cancer cells from normal cells. The technique, which is based on the density of cells seen on a microscope slide, may eventually lead to better ways for surgeons to determine if they have removed all of the cancer during breast-conserving cancer surgery and cut down on the number of needed second operations. http://www.physorg.com/news152541315.html Medicine & Health Fri, 30 Jan 2009 12:35:57 EST news152541315 "Remember when...?" is how many a wistful trip down memory lane begins. But just how the brain keeps tabs on what happened and when is still a matter of speculation. A computational model developed by scientists at the Salk Institute for Biological Studies now suggests that newborn brain cells -generated by the thousands each day -add a time-related code, which is unique to memories formed around the same time. http://www.physorg.com/news152377532.html Medicine & Health Wed, 28 Jan 2009 15:06:01 EST news152377532 (PhysOrg.com) -- Electrical engineers at the University of California, San Diego have achieved world-record speeds for real-time signal processing in an effort to meet ambitious goals set by the Defense Advanced Research Projects Agency (DARPA) to develop the first Terabit-scale technology for optical processing.

But previous studies of smokers in Sweden have suggested that many have done just that, by switching to smokeless tobacco. While not without health risks, smokeless tobacco is less harmful than cigarettes. With that in mind, an international team of researchers asked the question, `Should public health officials start promoting smokeless tobacco as a way to reduce the overall harm caused by tobacco?` The answer: `Not so fast.` http://www.physorg.com/news152209590.html Medicine & Health Mon, 26 Jan 2009 16:27:04 EST news152209590 (PhysOrg.com) -- Adah Almutairi, Ph.D., assistant professor in the Skaggs School of Pharmacy and Pharmaceutical Sciences at the University of California, San Diego, is first author of a paper recently published in the Proceedings of the National Academy of Sciences (PNAS.)
