New sources of biofuel to take pressure off traditional crops "Salt-loving algae could be the key to the successful development of biofuels as well as being an efficient means of recycling atmospheric carbon dioxide", Professor John Cushman of the University of Nevada told the Society for General Microbiology meeting at Heriot-Watt University, Edinburgh, today (10 September). http://www.physorg.com/news171781380.html Biology Thu, 10 Sep 2009 06:30:02 EST news171781380 Agricultural methods of early civilizations may have altered global climate, study suggests Massive burning of forests for agriculture thousands of years ago may have increased atmospheric carbon dioxide enough to alter global climate and usher in a warming trend that continues today, according to a new study that appears online Aug. 17 in the journal Quaternary Science Reviews. http://www.physorg.com/news169725512.html Space & Earth Mon, 17 Aug 2009 11:00:18 EST news169725512 Long debate ended over cause, demise of ice ages -- may also help predict future Researchers have largely put to rest a long debate on the underlying mechanism that has caused periodic ice ages on Earth for the past 2.5 million years - they are ultimately linked to slight shifts in solar radiation caused by predictable changes in Earth's rotation and axis. http://www.physorg.com/news168791411.html Space & Earth Thu, 06 Aug 2009 16:20:02 EST news168791411 NASA Releases Orbiting Carbon Observatory Accident Summary (PhysOrg.com) -- A NASA panel that investigated the unsuccessful Feb. 24 launch of the Orbiting Carbon Observatory, or OCO, has completed its report. http://www.physorg.com/news167053792.html Space & Earth Fri, 17 Jul 2009 13:10:01 EST news167053792 Mystery mechanism drove global warming 55 million years ago A runaway spurt of global warming 55 million years ago turned Earth into a hothouse but how this happened remains worryingly unclear, scientists said on Monday. http://www.physorg.com/news166715232.html Space & Earth Mon, 13 Jul 2009 14:47:39 EST news166715232 Forest fire prevention efforts will lessen carbon sequestration, add to greenhouse warming Widely sought efforts to reduce fuels that increase catastrophic fire in Pacific Northwest forests will be counterproductive to another important societal goal of sequestering carbon to help offset global warming, forestry researchers at Oregon State University conclude in a new report. http://www.physorg.com/news166273305.html Space & Earth Wed, 08 Jul 2009 12:40:01 EST news166273305 Iron and biological production in the high-latitude North Atlantic Southampton scientists have demonstrated an unexpected role of iron in regulating biological production in the high-latitude North Atlantic. Their findings have important implications for our understanding of ocean-climate interactions. http://www.physorg.com/news166187442.html Space & Earth Tue, 07 Jul 2009 12:11:08 EST news166187442 Researcher identifies protein that concentrates carbon dioxide in algae (PhysOrg.com) -- Increasing levels of carbon dioxide in the atmosphere are a concern to many environmentalists who research global warming. http://www.physorg.com/news158428436.html Biology Wed, 08 Apr 2009 16:54:20 EST news158428436 Invasive plants challenge scientists in face of environmental change Managing invasive plant species on the Great Plains has become more challenging in recent years in the face of human-caused environmental change, including the positive responses of invaders to altered atmospheric chemistry and longer growing seasons, says a University of Colorado at Boulder professor. http://www.physorg.com/news151074298.html Space & Earth Tue, 13 Jan 2009 13:04:58 EST news151074298
