Scientists have ruled out the possibility that methane is delivered to Mars by meteorites, raising fresh hopes that the gas might be generated by life on the red planet, in research published tomorrow in Earth and Planetary Science Letters. http://www.physorg.com/news179499648.html Space & Earth Tue, 08 Dec 2009 13:02:06 EST news179499648 A series of newly discovered pits in the bottom of the Hudson Canyon, 100 miles southeast of New York Harbor, may be a key ingredient for the abundant and diverse marine ecosystem in and around the canyon, according to research by scientists from Rutgers University and the National Oceanic and Atmospheric Administration. http://www.physorg.com/news178903141.html Space & Earth Tue, 01 Dec 2009 15:20:30 EST news178903141 A dangerous level of carbon dioxide and methane gas haunts Lake Kivu, the freshwater lake system bordering Rwanda and the Republic of Congo. http://www.physorg.com/news177606996.html Space & Earth Mon, 16 Nov 2009 15:50:02 EST news177606996 (PhysOrg.com) -- Researchers at the University of Washington and the University of North Carolina at Chapel Hill have taken an important step in converting methane gas to a liquid, potentially making it more useful as a fuel and as a source for making other chemicals. http://www.physorg.com/news175440723.html Chemistry Thu, 22 Oct 2009 14:32:49 EST news175440723 An abundant greenhouse gas could someday help clean up the earth. Converting methane to liquid methanol could produce clean, low-cost fuel and prevent the potent greenhouse gas from entering the atmosphere. Exploiting methane in this way could also produce a hydrogen source for fuel cells and yield other industrial applications. http://www.physorg.com/news175434422.html Chemistry Thu, 22 Oct 2009 13:10:01 EST news175434422 (AP) -- The smell of manure hangs over Greeley as it has for half a century. These days it's more than just a potent reminder of the region's agricultural roots and the hundreds of thousands of cattle raised on the city's outskirts. The stench smells like an opportunity. http://www.physorg.com/news175017016.html Technology Sat, 17 Oct 2009 17:00:02 EST news175017016 (AP) -- Only a squawk from a sandhill crane broke the Arctic silence - and a low gurgle of bubbles, a watery whisper of trouble repeated in countless spots around the polar world. http://www.physorg.com/news170863166.html Space & Earth Sun, 30 Aug 2009 15:10:02 EST news170863166 The Archaea are single-celled organisms and a domain unto themselves, quite apart from the so called eukaryotes, being bacteria and higher organisms. Many species live under extreme conditions, and carry out unique biochemical processes shared neither with bacteria nor with eukaryotes. Methanogenic archaeans, for example, can produce methane gas out of carbon dioxide and hydrogen. http://www.physorg.com/news165748836.html Biology Thu, 02 Jul 2009 10:21:37 EST news165748836 (PhysOrg.com) -- The Earth's original atmosphere held very little oxygen. This began to change around 2.4 billion years ago when oxygen levels increased dramatically during what scientists call the "Great Oxidation Event." The cause of this event has puzzled scientists, but researchers writing in Nature* have found indications in ancient sedimentary rocks that it may have been linked to a drop in the level of dissolved nickel in seawater. http://www.physorg.com/news158415685.html Space & Earth Wed, 08 Apr 2009 13:22:04 EST news158415685 Tubeworms have been around for millions of years and the fossil record is rich with their distinctive imprints. But a discovery made by U of C scientists found that what previous researchers had labeled as tubeworms in a formation near Denver, Colorado, are actually 70 million-year-old escape hatches for methane. http://www.physorg.com/news152972257.html Biology Wed, 04 Feb 2009 12:18:08 EST news152972257 Chemists at the University of Liverpool have developed a way of converting methane gas into a powder form in order to make it more transportable. http://www.physorg.com/news146398407.html Chemistry Thu, 20 Nov 2008 10:13:27 EST news146398407
