In this download, a month's worth of science data was transmitted through the NASA Deep Space Network and into the Science Operations Center at Ames Research Center. After the download was complete, the Kepler spacecraft was returned to its science collection attitude and another cycle of science data collection began. http://www.physorg.com/news176728311.html Space & Earth Fri, 06 Nov 2009 12:00:02 EST news176728311 An article in the Proceedings of the National Academy of Science written by a team of ecologists, including Robert Booth, assistant professor of earth and environmental science at Lehigh University, examines some of the potential problems with current prediction methods and calls for the use of a range of approaches when predicting the impact of climate change on organisms. http://www.physorg.com/news176555677.html Biology Wed, 04 Nov 2009 11:30:01 EST news176555677 (PhysOrg.com) -- While long-term projections call for higher temperatures and heat waves even more intense than previously thought, considerable geographic variability is also in the forecast, according to a study published in the Proceedings of the National Academy of Sciences. http://www.physorg.com/news173546838.html Space & Earth Wed, 30 Sep 2009 16:29:51 EST news173546838 (PhysOrg.com) -- In a study published in the September 24th issue of Nature, an international team describes how they harnessed modern genomic technology to explore the ancient history of India, the world's second most populous nation. http://www.physorg.com/news172931737.html Medicine & Health Wed, 23 Sep 2009 13:36:45 EST news172931737 (PhysOrg.com) -- Whether for introduced muskrats in Europe or oak trees in the United Kingdom, zebra mussels in United States lakes or agricultural pests around the world, scientists have tried to find new ways of controlling invasive species by learning how these animals and plants take over in new environs. http://www.physorg.com/news172429473.html Biology Thu, 17 Sep 2009 18:08:33 EST news172429473 Brown University scientists have taken the first steps toward mapping epigenetic variability in cells and tissues. Mapping the human epigenome, similar to the human genome project in the 1990s, could someday allow for quicker and more precise disease diagnoses and more targeted treatments of many chronic ailments. http://www.physorg.com/news169481370.html Medicine & Health Fri, 14 Aug 2009 15:10:17 EST news169481370 Just how rare life is in the Universe is one of the key questions in the natural sciences today. By pulling in multidisciplinary expertise from biology, geology, physics and astronomy, astrobiologists are addressing different facets of this very profound question, and notably how the conditions around different types of stars in an early stage of development might help or hinder the emergence of life in a solar system. Several scientists at the forefront of this research have just concluded IAU Symposium 264 on "Solar and Stellar Variability -- impact on Earth and Planets". http://www.physorg.com/news169134421.html Space & Earth Mon, 10 Aug 2009 15:40:13 EST news169134421 Rather than sticking to a single DNA script, human brain cells harbor astonishing genomic variability, according to scientists at the Salk Institute for Biological Studies. The findings, to be published in the Aug. 5, 2009, advance online edition of Nature, could help explain brain development and individuality, as well as lead to a better understanding of neurological disease. http://www.physorg.com/news168697506.html Medicine & Health Wed, 05 Aug 2009 13:25:34 EST news168697506 (PhysOrg.com) -- A recent study on human genetics on various populations across the world conducted by researchers from the Institut Pasteur and the CNRS (France) has shown how pathogens can shape the patterns of genetic diversity of our immune system over time. Results show that bacteria, fungi and parasites, unlike viruses, appear to have allowed the introduction of mutations in the genes of some proteins of the innate immunity system, thus enabling greater genetic variability. In some cases, these mutations may even constitute an advantage, giving the human host improved resistance to infectious diseases such as leprosy or tuberculosis. http://www.physorg.com/news168014649.html Medicine & Health Tue, 28 Jul 2009 15:45:45 EST news168014649 They are cursed the world over for contaminating food supplies and are a huge commercial pest, but the humble flour beetle is about to play a significant role in the management of endangered species. http://www.physorg.com/news161949561.html Biology Tue, 19 May 2009 10:59:49 EST news161949561 The Neanderthals inhabited a vast geographical area extending from Europe to western Asia and the Middle East 30,000 to 100,000 years ago. Now, a group of researchers are questioning whether or not the Neanderthals constituted a homogenous group or separate sub-groups (between which slight differences could be observed). A new study published April 15 in the online, open-access, peer-reviewed journal PLoS ONE may provide some answers. http://www.physorg.com/news158992826.html Biology Wed, 15 Apr 2009 05:47:34 EST news158992826 Liver cirrhosis is the seventh leading cause of death in the United States, taking 25,000 lives per year. It is often the result of alcohol over-consumption or exposure to hepatitis C, either of which can damage the liver and prevent it from filtering toxins. These toxins then accumulate in the blood stream and eventually reach the brain where they disrupt neurological and mental performance, a condition known as hepatic encephalopathy. http://www.physorg.com/news153474130.html Medicine & Health Tue, 10 Feb 2009 09:17:14 EST news153474130 (PhysOrg.com) -- Like most sub-Saharan African countries, Niger faces problems meeting its water needs. As part of ESA`s TIGER initiative, satellite data are being used to identify surface and underground water resources in the drought-prone country. http://www.physorg.com/news151593363.html Space & Earth Mon, 19 Jan 2009 13:16:45 EST news151593363 A recent study forecasts that increased climatic variability poses serious consequence for both the biodiversity and ecosystem function of high-elevation lakes. http://www.physorg.com/news138977383.html Space & Earth Tue, 26 Aug 2008 13:49:43 EST news138977383 A preliminary report published in the August 20 issue of JAMA suggests that within-person variability on neuropsychological testing may be associated with development of dementia in older adults. http://www.physorg.com/news138381753.html Medicine & Health Tue, 19 Aug 2008 16:22:33 EST news138381753
