| Weight-bearing exercise does not prevent increased bone turnover during weight loss Thu, 11 Mar 2010 00:00:00 EST |
(University of Missouri-Columbia) During weight loss, bones are being remodeled -- breaking down old bone and forming new bone -- at an accelerated rate. As a result, bone density is reduced, causing increased fragility. In a new study, University of Missouri researchers found that weight-bearing exercise, in this case, fast walking or jogging, did not prevent the increased bone turnover caused by weight loss. |
| Aquatic 'dead zones' contributing to climate change Thu, 11 Mar 2010 00:00:00 EST |
(University of Maryland Center for Environmental Science) The increased frequency and intensity of oxygen-deprived "dead zones" along the world's coasts can negatively impact environmental conditions in far more than local waters. In the March 12 edition of Science, UMCES oceanographer Dr. Lou Codispoti explains that the increased amount of nitrous oxide produced in hypoxic waters can elevate concentrations in the atmosphere, further exacerbating the impacts of global warming and contributing to ozone "holes" that increase our exposure to harmful UV radiation. |
| New imaging technology brings trace chemicals into focus Thu, 11 Mar 2010 00:00:00 EST |
(Arizona State University) Arizona State University scientist N.J. Tao and his colleagues at the Biodesign Institute have hit on a new, versatile method to significantly improve the detection of trace chemicals important in such areas as national security, human health and the environment. Tao's team was able to detect and identify tiny particles of the explosive trinitrotoluene or TNT -- each weighing less than a billionth of a gram -- on the ridges and canals of a fingerprint. |
| Shocking recipe for making killer electrons Thu, 11 Mar 2010 00:00:00 EST |
