Without at least a temporary reprieve from hunting, the world's largest species of fruit bat, Pteropus vampyrus or the "large flying fox", could be driven to extinction in Peninsular Malaysia at the current hunting rate, scientists have warned. Writing in the new issue of the British Ecological Society's Journal of Applied Ecology, they say around 22,000 flying foxes are legally hunted (in addition to those illegally hunted) each year in Peninsular Malaysia, a level of hunting that is unsustainable based on their estimates of the number of bats in the country. http://www.physorg.com/news170447435.html Biology Tue, 25 Aug 2009 19:40:02 EST news170447435 (PhysOrg.com) -- Drinking beetroot juice boosts your stamina and could help you exercise for up to 16% longer. A University of Exeter led-study, published today, shows for the first time how the nitrate contained in beetroot juice leads to a reduction in oxygen uptake, making exercise less tiring. http://www.physorg.com/news168787342.html Medicine & Health Thu, 06 Aug 2009 15:40:09 EST news168787342 Years of research suggest that the promises organizations make to employees matter in establishing and maintaining a "psychological contract" between the two parties. However, new research by Samantha Montes and co-author David Zweig, professors at the University of Toronto's Rotman School of Management and the University of Toronto Scarborough, suggests that what an organization promises to employees (e.g., training opportunities, benefits, compensation) don't matter nearly as much as what the organization actually delivers. http://www.physorg.com/news168608148.html Other Sciences Tue, 04 Aug 2009 13:00:01 EST news168608148 Divers who held their breath for several minutes had elevated levels of a protein that can signal brain damage, according to a new study from the Journal of Applied Physiology. However, the appearance of the protein, S100B, was transient and leaves open the question of whether lengthy apnea (breath-holding) can damage the brain over the long term. http://www.physorg.com/news168598483.html Medicine & Health Tue, 04 Aug 2009 09:55:06 EST news168598483 (PhysOrg.com) -- Recent research into the properties of graphene nanoribbons provides two new reasons for using the material as interconnects in future computer chips.

This necessitates collecting energy from ambient sources including wind, solar, and geothermal power, and converting it into appropriate forms for distributing electricity. While it is possible for this electric power to be distributed efficiently, conversion is necessary for use in automobiles and large-scale storage is problematic. http://www.physorg.com/news167659860.html Other Sciences Fri, 24 Jul 2009 13:30:01 EST news167659860 When soldiers leave base for a 3-day mission, how much water should they bring?
