Berkeley CA (SPX) Mar 07, 2013 – It’s among the most ancient of questions: What are the origins of life on Earth? A new experiment simulating conditions in deep space reveals that the complex building blocks of life could have been created on icy interplanetary dust and then carried to Earth, jump-starting life. Chemists from the University of California, Berkeley, and the University of Hawaii, Manoa, showed that conditi … more

Ancient meteorite impact in Iowa studied
Decorah, Iowa (UPI) Mar 5, 2013 – Airborne surveys are providing an unprecedented look at a 470-million-year-old meteorite crater in Iowa concealed by bedrock and sediment, geologists say. The aerial surveys were conducted around Decorah, Iowa, within the past 60 days to map geologic structures and assess the mineral and water resources of the region, the U.S. Geological Survey said in a release Tuesday. “Capturi … more

Modeling Jupiter and Saturn’s possible origins
Washington DC (SPX) Mar 07, 2013 – New theoretical modeling by Carnegie’s Alan Boss provides clues to how the gas giant planets in our solar system-Jupiter and Saturn-might have formed and evolved. His work was published recently by the Astrophysical Journal. New stars are surrounded by rotating gas disks during the early stages of their lives. Gas giant planets are thought to form in the presence of these disks. Obse … more

Mysterious electron stash found hidden among Van Allen belts
Los Alamos NM (SPX) Mar 07, 2013 – U.S. researchers, including a trio from Los Alamos National Laboratory, have witnessed the mysterious appearance of a relatively long-lived zone of high-energy electrons stored between Earth’s Van Allen radiation belts. The surprising findings, discovered by NASA’s Van Allen Probes (formerly known as the Radiation Belt Storm Probes), were outlined Thursday in Science Express and during a p … more
