With climate change looming, the hunt for places that can soak up carbon dioxide from the atmosphere is on. http://www.physorg.com/news158256801.html Space & Earth Mon, 06 Apr 2009 17:13:49 EST news158256801 The Xingu River, the largest tributary of the Amazon, runs wide and swift this time of year. Its turquoise waters are home to some 600 species of fish, including several not found anywhere else on the planet. A thick emerald canopy of trees hugs its banks, except in places where man has carved out pastures for cattle. http://www.physorg.com/news158154937.html Space & Earth Sun, 05 Apr 2009 12:56:33 EST news158154937 (PhysOrg.com) -- New research shows that for millions of years carbon dioxide has been stored safely and naturally in underground water in gas fields saturated with the greenhouse gas. The findings - published in Nature today - bring carbon capture and storage a step closer. http://www.physorg.com/news157814050.html Space & Earth Wed, 01 Apr 2009 14:14:36 EST news157814050 As sea levels rise in the wake of climate change and semi-arid regions turn to desert, people living in those parts of the world are likely to be displaced. A mathematical approach to planned relocation reported in the International Journal of Mathematics and Operational Research. http://www.physorg.com/news157808944.html Other Sciences Wed, 01 Apr 2009 12:49:31 EST news157808944 Nitrous oxide is a potent greenhouse gas that has been accumulating in the atmosphere since the industrial revolution. It is well known that fertilizer can stimulate nitrous oxide production in soils, but less is known about nitrous oxide production in small streams which drain agricultural landscapes. Much of the cropland in the agricultural Midwest is drained by an extensive subsurface drainage network which delivers soil-derived nitrate to small streams where it may be converted to nitrous oxide. Given the large quantities of nitrogen that leach from agricultural soils and the predominance of small streams in Midwestern agricultural landscapes, small streams may an important source of nitrous oxide. http://www.physorg.com/news157632680.html Space & Earth Mon, 30 Mar 2009 11:52:04 EST news157632680 A hungry student at the University of San Francisco earlier this month couldn't find a few college staples at the campus eatery -- a juicy hamburger and a cheesy slice of pizza. http://www.physorg.com/news157618216.html Space & Earth Mon, 30 Mar 2009 07:51:02 EST news157618216 The benefits to animals of omega 3 fatty acids in fish oils have been well documented - helping the heart and circulatory system, improving meat quality and reducing methane emissions. http://www.physorg.com/news157615993.html Biology Mon, 30 Mar 2009 07:13:54 EST news157615993 UN talks tasked with forging a global climate treaty by year's end were set to resume here on Sunday, with all eyes on the debut appearance of US negotiators from the administration of US President Barack Obama. http://www.physorg.com/news157560066.html Space & Earth Sun, 29 Mar 2009 15:41:41 EST news157560066 (PhysOrg.com) -- Stanford University researchers have developed a synthetic wood substitute that may one day save trees, reduce greenhouse gas emissions and shrink landfills. http://www.physorg.com/news156526288.html Chemistry Tue, 17 Mar 2009 16:32:31 EST news156526288 Tiny creatures at the bottom of the food chain called diatoms suck up nearly a quarter of the atmosphere's carbon dioxide, yet research by Michigan State University scientists suggests they could become less able to "sequester" that greenhouse gas as the climate warms.
