Researchers from the University of Southampton have drawn together 200 years' worth of oceanographic knowledge to investigate the distribution of a notorious deep-sea giant - the king crab. The results, published this week in the Journal of Biogeography, reveal temperature as a driving force behind the divergence of a major seafloor predator; globally, and over tens of millions of years of Earth's history. http://www.physorg.com/news165738541.html Biology Thu, 02 Jul 2009 07:29:24 EST news165738541 Pioneering therapeutic trials to investigate the effectiveness of deep brain stimulation (DBS) in hard-to-treat depression, obsessive-compulsive disorder (OCD) and Tourette's syndrome are underway at multiple medical centers around the world, according to a review in the June 2009 issue of Mayo Clinic Proceedings. http://www.physorg.com/news165494463.html Medicine & Health Mon, 29 Jun 2009 11:41:59 EST news165494463 (PhysOrg.com) -- An international oceanographic research expedition to the middle of the South Pacific Gyre - a site that is as far from continents as it is possible to go on Earth's surface - found so few organisms beneath the seafloor that it may be the least inhabited sediment ever explored for evidence of life. http://www.physorg.com/news164904604.html Space & Earth Mon, 22 Jun 2009 15:50:44 EST news164904604 Thirty tigers have died in the country's various sanctuaries and reserves this year.

As many as 250,000 people in the United States have dystonia, making it the third most common movement disorder behind essential tremor and Parkinson`s disease. The prevalence of generalized primary dystonia is estimated at 34 in 100,000 people worldwide, but cited statistics vary. This figure is most likely an underestimate, since many cases go undiagnosed for years. http://www.physorg.com/news160728387.html Medicine & Health Tue, 05 May 2009 07:46:59 EST news160728387 A drug widely used to treat seizures and anxiety appears to be an effective treatment for restless legs syndrome (RLS) and helps people with the disorder get a better night's sleep, according to a study that will be presented as part of the Late-breaking Science Program at the American Academy of Neurology's 61st Annual Meeting in Seattle, April 25 - May 2, 2009.
