Chemist Travels World to Study Mysterious Properties of Neutrinos In the quest to better understand one of nature's most "ghostly" elementary particles — the neutrino — scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory are spreading their expertise from the mines of Canada to the mountains of China. Richard L. Hahn, a senior chemist at Brookhaven Lab, will discuss some of the neutrino's mysterious properties and two new neutrino research projects at the 236th National Meeting of the American Chemical Society on Tuesday, August 19, 2008. Good long-term prognosis after West Nile virus infection The long-term prognosis of patients infected with West Nile virus is good, according to a new study appearing in the August 19, 2008, issue of Annals of Internal Medicine, the American College of Physicians' flagship journal. This is the largest study of the long-term outcomes of West Nile virus infection. Future impact of global warming is worse when grazing animals are considered, scientists suggest The impact of global warming in the Arctic may differ from the predictions of computer models of the region, according to a pair of Penn State biologists. The team -- which includes Eric Post, a Penn State associate professor of biology, and Christian Pederson, a Penn State graduate student -- has shown that grazing animals will play a key role in reducing the anticipated expansion of shrub growth in the region, thus limiting their predicted and beneficial carbon-absorbing effect. The team's results will be published in the online Early Edition of the journal Proceedings of the National Academy of Sciences sometime between 18 and 22 August 2008. Signals from the Atlantic salmon highway For years scientists have struggled to understand the decline and slow recovery of Atlantic salmon, a once abundant and highly prized game and food fish native to New England rivers. Biologists agree that poor marine survival is affecting salmon in the U.S. and Canada, but specific causes are difficult to determine in the ocean. Small acoustic tags and associated technology may provide some answers. Soils Limited in Storing Carbon and Mitigating Global Warming, Studies Find (PhysOrg.com) -- Soils, long known to be potential natural "sinks" or storehouses for carbon, are limited in just how much carbon they can stash away, according to two recent studies by researchers at UC Davis; University of Kentucky; University of Bonn, Germany; and Agriculture and Agri-Food Canada. Mummified remains from 1948 plane crash identified (AP) -- Nine years of sleuthing, advanced DNA science and cutting-edge forensic techniques have finally put a name to a mummified hand and arm found in an Alaska glacier. New case of mad cow disease detected in Canada A new case of mad cow disease has been detected in the western Canadian province of Alberta, the government's Food Inspection Agency announced Friday. Skepticism as US hunters claim 'Bigfoot' find Two US men on Friday claimed to have found the body of "Bigfoot," the legendary ape-like creature that has been the subject of decades of hoaxes and dubious sightings. FDA says chemical found in plastic bottles is safe (AP) -- Despite ongoing safety concerns from parents, consumer groups and politicians, a chemical used in baby bottles, canned food and other items is not dangerous, federal regulators said Friday. Canada to search for Arctic explorer's ships (AP) -- For more than 160 years, the fate of British explorer Sir John Franklin and his men has remained locked in the frozen Arctic, but warming temperatures are threatening to change that. ... |
