(2009-10-28) Ethiopia 27 million years ago had higher rainfall, warmer soil Thirty million years ago, before Ethiopia's mountainous highlands split and the Great Rift Valley formed, the tropical zone had warmer soil temperatures, higher rainfall and different atmospheric circulation patterns than it does today, according to new research of fossil soils found in the central African nation. (2009-10-23) Arctic lake sediments show warming, unique ecological changes in recent decades An analysis of sediment cores indicates that biological and chemical changes occurring at a remote Arctic lake are unprecedented over the past 200,000 years and likely are the result of human-caused climate change, according to a new study led by the University of Colorado at Boulder. (2009-10-20) West Antarctic ice sheet may not be losing ice as fast as once thought New ground measurements made by the West Antarctic GPS Network (WAGN) project, composed of researchers from The University of Texas at Austin, The Ohio State University, and The University of Memphis, suggest the rate of ice loss of the West Antarctic ice sheet has been slightly overestimated. (2009-10-20) Iron isotopes as a tool in oceanography New research involving scientists from the National Oceanography Centre, Southampton (NOCS) highlights the potential utility of iron isotopes for addressing important questions in ocean science. (2009-07-31) Apollo 11 moon rocks still crucial 40 years later, say WUSTL researchers A lunar geochemist at Washington University in St. Louis says that there are still many answers to be gleaned from the moon rocks collected by the Apollo 11 astronauts on their historic moonwalk 40 years ago July 20. (2009-07-20) Magnetic Tornadoes Could Liberate Mercury's Tenuous Atmosphere As the closest planet to the sun, Mercury is scorching hot, with daytime temperatures of more than 800 degrees Fahrenheit (approximately 450 degrees Celsius). (2009-06-03) New research study reveals origin of volcano's carbon-based lavas Scientists studying the world's most unusual volcano have discovered the reason behind its unique carbon-based lavas.
