If the strain goes on too long, it can lead to debilitating psychological problems. Part of the reason, according to scientists at The Rockefeller University, may have to do with a little-known family of proteins called kainate receptors that has recently been implicated in major depression. New research in rats may help explain one mechanism by which stress reshapes the brain: namely, by ramping up production of a particular part of these proteins. http://www.physorg.com/news154887406.html Medicine & Health Thu, 26 Feb 2009 16:23:19 EST news154887406 Children with high blood pressure are not as good at complicated, goal-directed tasks, have more working memory problems and are not as adept at planning as their peers without hypertension, according to recent research.

The system, called "Protection Poker," was developed by computer security experts at North Carolina State University and is already being used in a pilot project to identify security problems. http://www.physorg.com/news154694556.html Technology Tue, 24 Feb 2009 10:43:13 EST news154694556 (PhysOrg.com) -- Past behavior is generally considered to be a good predictor of future behavior, but new research indicates that may not be the case in the development of depression, particularly among adolescent girls. http://www.physorg.com/news154113418.html Medicine & Health Tue, 17 Feb 2009 17:21:40 EST news154113418 The research, published today in the British Medical Journal, highlighted a 44% increase in risk of cognitive impairment when exposed to high levels of second-hand smoke. http://www.physorg.com/news153722127.html Medicine & Health Fri, 13 Feb 2009 04:35:54 EST news153722127 Getting help for a problem PC can be a confusing and frustrating process.

Although far from proving anything about human use of the drug, the finding supports the scientific quest for a substance that could treat progressive cognitive impairment, cushion the cognitive impact of normal aging, or even enhance learning and memory throughout the life span. http://www.physorg.com/news152773555.html Medicine & Health Mon, 02 Feb 2009 05:06:18 EST news152773555 A study in the Feb. 1 issue of the journal Sleep was the first to use twin data to examine the longitudinal link between sleep problems and depression. Results of this study demonstrate that sleep problems predict later depression; the converse association was not found. These findings are consistent with the theory that early treatment of sleep problems may protect children from the development of depression. http://www.physorg.com/news152721800.html Medicine & Health Sun, 01 Feb 2009 14:43:45 EST news152721800 People who wolf down their food are more likely to be overweight and suffer from digestive problems. http://www.physorg.com/news152543084.html Medicine & Health Fri, 30 Jan 2009 13:05:10 EST news152543084 High levels of certain proteins in the spinal fluid could signal the onset of Lou Gehrig's disease, according to researchers.

The August 2005 storm was one of the most powerful and deadliest hurricanes in U.S. history. Hurricane Katrina displaced thousands and severely disrupted access to health care. Researchers monitored enrollees of a New Orleans-area managed care organization and found morbidity rates increased 12.6 percent compared with 3.4 percent nationwide. The results are published in the January issue of The American Journal of Managed Care. http://www.physorg.com/news151855538.html Medicine & Health Thu, 22 Jan 2009 14:06:45 EST news151855538 Many of the 40 million American adults who suffer from anxiety disorders also have problems with balance. As increasing numbers of children are diagnosed with anxiety, Tel Aviv University researchers have discovered that the link between balance and anxiety can be assessed at an early age - and that something can be done about it before it becomes a problem. http://www.physorg.com/news151853201.html Medicine & Health Thu, 22 Jan 2009 13:27:09 EST news151853201 Pediatricians usually have about seven minutes to sit face-to-face with patients during a typical visit.

To determine if a fading sense of smell may signal Parkinson`s, researchers at Northwestern Memorial Hospital and Northwestern University`s Feinberg School of Medicine are participating in a national study to examine the correlation and ascertain whether smell loss presents a tool for early detection of the disease and an opportunity to delay or ultimately prevent more troublesome symptoms. http://www.physorg.com/news151689638.html Medicine & Health Tue, 20 Jan 2009 16:03:50 EST news151689638 New research strengthens the link between water pollution and rising male fertility problems.

Is it better for children to learn gradually, starting with easy examples and slowly progressing to more challenging problems? Or is it more effective to just dive-in head first with difficult problems, and then move on to easier examples? Although conventional wisdom suggests that the best way to learn a difficult skill is to progress from easier problems to more difficult ones, research examining this issue has resulted in mixed outcomes. http://www.physorg.com/news147353581.html Medicine & Health Mon, 01 Dec 2008 11:33:01 EST news147353581 Internet network performance problems are not only annoying to users -- they are costly to businesses and network operators.
