Following two months of commissioning, during which the spacecraft and sensors were tuned for optimum mission performance, the Interstellar Boundary Explorer (IBEX) spacecraft began gathering data to build the first maps of the edge of the heliosphere, the region of space influenced by the Sun. http://www.physorg.com/news151152484.html Space & Earth Wed, 14 Jan 2009 10:48:04 EST news151152484 (PhysOrg.com) -- The evolutionary history of diatoms -- abundant oceanic plankton that remove billions of tons of carbon dioxide from the air each year -- needs to be rewritten, according to a new Cornell study. The findings suggest that after a sudden rise in species numbers, diatoms abruptly declined about 33 million years ago -- trends that coincided with severe global cooling. http://www.physorg.com/news150642726.html Biology Thu, 08 Jan 2009 13:12:06 EST news150642726 Climate researchers have shown that big volcanic eruptions over the past 450 years have temporarily cooled weather in the tropics -but suggest that such effects may have been masked in the 20th century by rising global temperatures. Their paper, which shows that higher latitudes can be even more sensitive to volcanism, appears in the current issue of Nature Geoscience. http://www.physorg.com/news150397996.html Space & Earth Mon, 05 Jan 2009 17:13:16 EST news150397996 Government insurance programs that safeguard bank deposits should be reformed to ease taxpayers' undue stake in propping up the nation's banking system, according to research by a University of Illinois finance professor. http://www.physorg.com/news150389244.html Other Sciences Mon, 05 Jan 2009 14:47:24 EST news150389244 (PhysOrg.com) -- The frequency of extremely high clouds in Earth's tropics -- the type associated with severe storms and rainfall -- is increasing as a result of global warming, according to a study by scientists at NASA's Jet Propulsion Laboratory, Pasadena, Calif. http://www.physorg.com/news148916785.html Space & Earth Fri, 19 Dec 2008 13:46:25 EST news148916785 (PhysOrg.com) -- A new study supports earlier findings by stating that changes in cosmic rays most likely do not contribute to climate change. http://www.physorg.com/news148751093.html Space & Earth Wed, 17 Dec 2008 15:44:53 EST news148751093 A global energy supply based on biomass grown to generate electricity and produce fuel is a real possibility. According to Prof. Jürgen O. Metzger from Carl von Ossietzky University of Oldenburg in Germany and Prof. Aloys Huettermann from the University of Goettingen in Germany, it is both a sustainable and economical scenario, contrary to current thinking which suggests it is unrealistic. Their findings are published online this week in Springer's journal, Naturwissenschaften. http://www.physorg.com/news148561778.html Biology Mon, 15 Dec 2008 11:09:38 EST news148561778 This has made it possible to determine, for the first time, the frequency of such polar lows in the past. http://www.physorg.com/news148315412.html Space & Earth Fri, 12 Dec 2008 14:43:32 EST news148315412 Modern day concentrations of ground level ozone pollution are decreasing the growth of trees in the northern and temperate mid-latitudes, as shown in a paper publishing today in Global Change Biology.
