(PhysOrg.com) -- Just as people plug in to computers, smart phones and electric outlets to communicate, electric fish communicate by quickly plugging special channels into their cells to generate electrical impulses, University of Texas at Austin researchers have discovered. http://www.physorg.com/news173418765.html Biology Tue, 29 Sep 2009 04:53:16 EST news173418765 Researchers in China have discovered the first protein-based toxin in an amphibian -a 60 amino acid neurotoxin found in the skin of a Chinese tree frog. This finding may help shed more light into both the evolution of amphibians and the evolution of poison. http://www.physorg.com/news169734166.html Chemistry Mon, 17 Aug 2009 13:25:14 EST news169734166 The May 2009 issue of the Journal of General Physiology features an article and accompanying commentary on new experimental evidence that advances previous conclusions about the essential features of the Shaker K+ channel, a voltage-gated potassium (Kv) channel. http://www.physorg.com/news160045875.html Medicine & Health Mon, 27 Apr 2009 10:13:51 EST news160045875 Studies at the University of Pennsylvania School of Medicine on brain electrical signaling offer a fresh perspective on vertebrate evolution, provide additional evidence supporting Darwinian views of evolution, and may also lead to more effective treatment of epileptic seizures in infants. Researchers discovered how evolutionary changes produced a series of improvements in molecules generating electrical signals in nerves between 550 and 400 million years ago. By making nervous systems faster and smarter, these innovations appear to have contributed to the evolutionary success and diversity of vertebrate animals. http://www.physorg.com/news151687890.html Medicine & Health Tue, 20 Jan 2009 15:32:26 EST news151687890 A compound designed to prevent chest pains in heart patients has shown promising results in animal studies, say scientists. In the second issue of the British Journal of Pharmacology to be published by Wiley-Blackwell, researchers from the Centre de Recherche Pierre Fabre in France, show that the novel compound F15845 has anti-angina activity and can protect heart cells from damage without the unwanted side effects often experienced with other drugs. http://www.physorg.com/news150536526.html Medicine & Health Wed, 07 Jan 2009 07:42:06 EST news150536526 Fifteen percent to 20 percent of people worldwide suffer from migraines - excruciating headaches often presaged by dramatic sensations, or "auras." By studying a rare, inherited form of migraine, researchers at Vanderbilt University Medical Center have found clues to the biological basis of the painful, debilitating disorder. http://www.physorg.com/news134064911.html Medicine & Health Mon, 30 Jun 2008 17:15:11 EST news134064911
