(PhysOrg.com) -- Ethanol, often promoted as a clean-burning, renewable fuel that could help wean the nation from oil, would likely worsen health problems caused by ozone, compared with gasoline, especially in winter, according to a new study led by Stanford researchers. http://www.physorg.com/news180011426.html Space & Earth Mon, 14 Dec 2009 11:11:32 EST news180011426 Dartmouth researchers have determined that the presence of the rare element osmium is on the rise globally. They trace this increase to the consumption of refined platinum, the primary ingredient in catalytic converters, the equipment commonly installed in cars to reduce smog. A volatile form of osmium is generated during platinum refinement and also during the normal operation of cars, and it gets dispersed globally through the atmosphere. http://www.physorg.com/news159544802.html Space & Earth Tue, 21 Apr 2009 15:00:22 EST news159544802 A method of producing synthetic bone, using techniques normally used to make catalytic converters for cars, is being developed by researchers at WMG at the University of Warwick. http://www.physorg.com/news147615891.html Medicine & Health Thu, 04 Dec 2008 12:24:51 EST news147615891
