 Biochar quiets microbes, including some plant pathogens Houston TX (SPX) Oct 03, 2013 - In the first study of its kind, Rice University scientists have used synthetic biology to study how a popular soil amendment called "biochar" can interfere with the chemical signals that some microbes use to communicate. The class of compounds studied includes those used by some plant pathogens to coordinate their attacks. Biochar is charcoal that is produced - typically from waste wood, m ... more |  |
 How much of thallium pollutants will be released to environment by utilizing minerals?

 Climate change: Fast out of the gate, slow to the finish the gate Washington DC (SPX) Oct 03, 2013 - A great deal of research has focused on the amount of global warming resulting from increased greenhouse gas concentrations. But there has been relatively little study of the pace of the change following these increases. A new study by Carnegie's Ken Caldeira and Nathan Myhrvold of Intellectual Ventures concludes that about half of the warming occurs within the first 10 years after an inst ... more |  |
 New fossils push the origin of flowering plants back by 100 million years to the early Triassic Lausanne, Switzerland (SPX) Oct 03, 2013 - Drilling cores from Switzerland have revealed the oldest known fossils of the direct ancestors of flowering plants. These beautifully preserved 240-million-year-old pollen grains are evidence that flowering plants evolved 100 million years earlier than previously thought, according to a new study in the open-access journal Frontiers in Plant Science. Flowering plants evolved from extinct p ... more |  |

 ForWarn follows rapidly changing forest conditions Washington DC (SPX) Oct 03, 2013 - U.S. Forest Service and partner scientists are keeping a watchful eye on forest health. As fall colors replace the lush greenness of spring and summer, researchers recognize telltale signs of change in healthy forests. A new publication highlights specific examples where researchers have used ForWarn, a state-of-the-art forest change recognition and tracking system, to detect disturbances ... more |  |
 Traces of immense prehistoric ice sheets: the climate history of the Arctic Ocean needs to be rewritten Bremerhaven, Germany (SPX) Oct 03, 2013 - Geologists and geophysicists of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), discovered traces of large ice sheets from the Pleistocene on a seamount off the north-eastern coast of Russia. These marks confirm for the first time that within the past 800,000 years in the course of ice ages, ice sheets more than a kilometre thick also formed in the Arctic Ocea ... more |  |
Protecting the weedy and wild kin of globally important crops Washington DC (SPX) Oct 03, 2013 - Over the past few decades, crop breeders have increasingly relied on the wild and weedy relatives of domesticated crops as new sources of disease resistance, drought tolerance, and other traits. But just like all wild plant species, these "crop wild relatives" (CWR) are also at risk of decline and extinction due to habitat loss, pollution, and climate change. On Wednesday, Nov. 6, 2013, tw ... more |  |
Fossils push flowering plants back to early Triassic Zurich, Switzerland (SPX) Oct 03, 2013 - Flowering plants evolved from extinct plants related to conifers, ginkgos, cycads, and seed ferns. The oldest known fossils from flowering plants are pollen grains. These are small, robust and numerous and therefore fossilize more easily than leaves and flowers. An uninterrupted sequence of fossilized pollen from flowers begins in the Early Cretaceous, approximately 140 million years ago, ... more |  |
Understanding soil nitrogen management using synchrotron technology Saskatoon, Canada (SPX) Oct 03, 2013 - As food security becomes an increasingly important global issue, scientists are looking for the best way to maintain the organic matter in soils using different methods of fertilization and crop rotation. Increasing the organic matter in soils is key to growing crops for numerous reasons, including increased water-holding capacity and improved tilth. Scientists have recently used the Canad ... more |  |

 SUNRISE Offers New Insight on Sun's Atmosphere Greenbelt MD (SPX) Oct 02, 2013 - Three months after the flight of the solar observatory Sunrise - carried aloft by a NASA scientific balloon in early June 2013 - scientists from the Max Planck Institute for Solar System Research in Germany have presented unique insights into a layer on the sun called the chromosphere. Sunrise provided the highest-resolution images to date in ultraviolet light of this thin corrugated layer ... more |  |
Lunar orbiters discover source of space weather near Earth Los Angeles CA (SPX) Oct 02, 2013 - Solar storms - powerful eruptions of solar material and magnetic fields into interplanetary space - can cause what is known as "space weather" near Earth, resulting in hazards that range from interference with communications systems and GPS errors to extensive power blackouts and the complete failure of critical satellites. New research published today increases our understanding of Earth' ... more |  |
