New analysis of global fisheries data suggests marine ecosystems can recover
— 31 Jul 2009 | EnvironmentAn international team of scientists with divergent views on ocean ecosystems has found that efforts to rebuild many of the world's fisheries are worthwhile and starting to pay off in many places around the world. Their study puts into perspective recent reports predicting a total collapse of global fisheries within 40 years…
Discovery about behaviour of building block of nature could lead to computer revolution
— 31 Jul 2009 | PhysicsA team of physicists from the Universities of Cambridge and Birmingham have shown that electrons in narrow wires can divide into two new particles called spinons and a holons…

Scientists warn restoration-based environmental markets may not improve ecosystem health
— 31 Jul 2009 | EnvironmentWhile policymakers across of the globe are relying on environmental restoration projects to fuel emerging market-based environmental programs, an article in the 31 July edition of Science by two noted ecologists warns that these programs still lack the scientific certainty needed to ensure that restoration projects deliver the environmental improvements being marketed…

Species barrier may protect macaques from chronic wasting disease
— 31 Jul 2009 | HealthData from an ongoing multi-year study suggest that people who consume deer and elk with chronic wasting disease (CWD) may be protected from infection by an inability of the CWD infectious agent to spread to people. The results to date show that 14 cynomolgus macaques exposed orally or intracerebrally to CWD remain healthy and symptom free after more than six years of observation, though the direct relevance to people is not definitive and remains under study. Cynomolgus macaques often are used as research models of human disease because they are very close genetically to humans and are susceptible to several forms of human brain-damaging disease. Thus, it was decided to see whether exposure to CWD could induce disease in the macaques. The study appears online in the journal Emerging Infectious Diseases…
Sun exposure may trigger certain autoimmune diseases in women
— 31 Jul 2009 | HealthUltraviolet (UV) radiation from sunlight may be associated with the development of certain autoimmune diseases, particularly in women, according to a study by researchers at the National Institute of Environmental Health Sciences (NIEHS), part of the National Institutes of Health…
Membrane breaks through performance barrier
— 31 Jul 2009 | ChemistryEngineers have developed a new method for creating high-performance membranes from crystal sieves called zeolites; the method could increase the energy efficiency of chemical separations up to 50 times over conventional methods and enable higher production rates…
