With DNA from just four cells, researchers reveal how some of the world's most abundant organisms play a key role in carbon cycling in the seabed. http://phys.org/news283607093.html Biology Wed, 27 Mar 2013 14:00:01 EST news283607093 Diverse underground ecosystems buried deep beneath the Earth's crust may offer clues to the origins of life on Earth, several recent studies have revealed. http://phys.org/news282632076.html Space & Earth Sat, 16 Mar 2013 05:54:45 EST news282632076 The Earth's oceanic crust covers an enormous expanse, and is mostly buried beneath a thick layer of mud that cuts it off from the surface world. Scientists now document life deep within the oceanic crust that appears to be sustained by energy released from chemical reactions of rocks with water. http://phys.org/news282481183.html Space & Earth Thu, 14 Mar 2013 14:00:13 EST news282481183 (Phys.org) -- Moqui marbles, unusual balls of rock that can be found rolling around the southwestern U.S. sandstone regions, were formed roughly 2 million years ago with the help of microorganisms. This discovery by a University of Nebraska-Lincoln research team has implications for finding life on Mars and for better understanding Earth's past. http://phys.org/news264319002.html Space & Earth Thu, 16 Aug 2012 06:56:59 EST news264319002 Microbiologists at Aarhus University (Denmark) have developed a new method for measuring the very slow metabolism of bacteria deep down in the seabed. The results can provide knowledge about the global carbon cycle and its long-term impact on the climate. http://phys.org/news251373641.html Biology Mon, 19 Mar 2012 11:00:48 EST news251373641 (PhysOrg.com) -- Another step toward improving understanding of electron exchange between microbes and minerals has been documented in the January 2010 issue of Geobiology. Bacteria such as the metal-reducing Shewanella oneidensis MR-1 exchange electrons with minerals in soil, sediment, and subsurface material. These interactions impact processes such as the reduction and stabilization of contaminants in groundwater. http://phys.org/news190925354.html Biology Mon, 19 Apr 2010 19:49:47 EST news190925354 Antarctica has long held secrets of the earth's history locked in its icy depths, and until recently, there has been very little information on the environments that have been sealed beneath miles of ice for millions of years. Now, a team of researchers from nine institutions - including LSU - have been funded to the tune of $10 million dollars by the National Science Foundation, or NSF, to get to the bottom of things - literally. These scientists will drill through the West Antarctic Ice Sheet and Ross Ice Shelf in Antarctica to directly access a subglacial lake and the cavity below the ice shelf. http://phys.org/news178293790.html Space & Earth Tue, 24 Nov 2009 14:40:02 EST news178293790
