While the focus of a shift from gasoline to biofuels has been on global warming, such a shift could also impact human health. A grant from the Energy Biosciences Institute (EBI) has produced a novel and comprehensive "Life Cycle Impact Assessment" to measure the benefits on human health that might result from a switch to biofuels. Although there are a number of uncertainties that must be addressed for a more accurate picture, these early results show that a biofuel eliminating even 10-percent of current gasoline pollutant emissions would have a substantial impact on human health in this country, especially in urban areas. http://www.physorg.com/news162736836.html Space & Earth Thu, 28 May 2009 13:41:12 EST news162736836 The Obama administration's plan to cut research dollars for hydrogen-powered cars is not good news for South Carolina and its capital city Columbia, which just last month opened two hydrogen fueling stations and unveiled the state's "hydrogen freeway." http://www.physorg.com/news161143205.html Technology Sun, 10 May 2009 03:00:48 EST news161143205 (AP) -- The top U.S. negotiator on climate change said Tuesday that he is slightly more optimistic about striking a new international agreement to curb global warming after a two-day meeting with the world's largest emitters of greenhouse gases. http://www.physorg.com/news160163818.html Space & Earth Tue, 28 Apr 2009 18:57:29 EST news160163818 (AP) -- U.S. Energy Secretary Steven Chu is warning that if countries don't do something about climate change, "some island states will simply disappear." http://www.physorg.com/news159344487.html Space & Earth Sun, 19 Apr 2009 07:21:57 EST news159344487
