To catalyze improvements in the techniques behind these predictions, the "eNMR" project has launched a new initiative. In September`s Nature Methods the project issued an invitation to the entire biomolecular Nuclear Magnetic Resonance community to participate in a large scale test of modern computing algorithms. This community-wide `contest` will potentially improve efficiency, reproducibility and reliability of NMR structure determination. eNMR will be using the Enabling Grids for E-sciencE infrastructure to power their analysis. http://www.physorg.com/news178785696.html Chemistry Mon, 30 Nov 2009 07:10:01 EST news178785696 A novel approach to classify the gender of six-week-old turkey poults could save millions of male chicks from being killed shortly after birth, according to Dr. Gerald Steiner from the Dresden University of Technology in Germany and his team. Their use of infrared spectroscopy to determine the gender of young birds shows that it is a fast and accurate method with the potential to be used by the breeding industry to identify and select female eggs for breeding. The pilot studyš has just been published online in Springer's journal Analytical and Bioanalytical Chemistry. http://www.physorg.com/news178216189.html Chemistry Mon, 23 Nov 2009 16:40:01 EST news178216189 Scientists at the Carnegie Institution have found for the first time that high pressure can be used to make a unique hydrogen-storage material. The discovery paves the way for an entirely new way to approach the hydrogen-storage problem. The researchers found that the normally unreactive, noble gas xenon combines with molecular hydrogen (H2) under pressure to form a previously unknown solid with unusual bonding chemistry. The experiments are the first time these elements have been combined to form a stable compound. The discovery debuts a new family of materials, which could boost new hydrogen technologies. http://www.physorg.com/news178119983.html Chemistry Sun, 22 Nov 2009 13:47:08 EST news178119983 Using highly precise measurements of plasma lipoprotein concentrations determined by nuclear magnetic resonance spectroscopy (NMR), researchers led by Daniel Chasman at Brigham and Women's Hospital and Harvard Medical School in Boston, MA, the Framingham Heart Study in Framingham, and the PROCARDIS consortium in Stockholm, Sweden and Oxford, England performed genetic association analysis across the whole genome among 17,296 women of European ancestry from the Women's Genome Health Study. http://www.physorg.com/news177945626.html Medicine & Health Fri, 20 Nov 2009 13:40:10 EST news177945626 Sustainable farming, initially adopted to preserve soil quality for future generations, may also play a role in maintaining a healthy climate, according to researchers at the Department of Energy's Oak Ridge and Los Alamos national laboratories. http://www.physorg.com/news177864926.html Space & Earth Thu, 19 Nov 2009 15:20:06 EST news177864926 (PhysOrg.com) -- Since the discovery in 2007 that a component of human semen called SEVI boosts infectivity of the virus that causes AIDS, researchers have been trying to learn more about SEVI and how it works, in hopes of thwarting its infection-promoting activity. http://www.physorg.com/news177859237.html Chemistry Thu, 19 Nov 2009 13:21:15 EST news177859237 Researchers from Boston University School of Medicine (BUSM) have shown that fat collection in different body locations, such as around the heart and the aorta and within the liver, are associated with certain decreased heart functions.
