Magnetism's subatomic roots - (Rice University) Theoretical physicists from Rice University have created a new model that helps define the subatomic origins of ferromagnetism -- the everyday "magnetism" of compass needles and refrigerator magnets. The model, which is detailed in a new paper in the Proceedings of the National Academy of Sciences, was created to explore the inner workings of ferromagnetic compounds that are related to high-temperature superconductors.... NASA hurricane researchers eye Earl's eye - (NASA/Goddard Space Flight Center) Three NASA aircraft carrying 15 instruments are busy criss-crossing Earl as part of the agency's Genesis and Rapid Intensification Processes mission, or GRIP, which continues through Sept. 30. GRIP is designed to help improve our understanding of how hurricanes such as Earl form and intensify rapidly.... GOES-13 satellite sees Hurricane Earl's clouds covering the US Northeast - (NASA/Goddard Space Flight Center) Hurricane Earl lashed the North Carolina coast last night and this morning, September 3, and is now headed for Cape Cod, Massachusetts. This morning's image from the GOES-13 satellite saw Hurricane Earl's clouds covering most of the northeastern US. ... Rutgers-Camden professor engineers E. coli to produce biodiesel - (Rutgers University) Desmond Lun, an associate professor of computer science at Rutgers University-Camden, is researching how to alter the genetic makeup of E. coli to produce biodiesel fuel derived from fatty acids.... Earth from space: Giant iceberg enters Nares Strait - (European Space Agency) ESA's Envisat satellite has been tracking the progression of the giant iceberg that calved from Greenland's Petermann glacier on August 4, 2010.... Census of Marine Life program tracking animals on Pacific continental shelf - (Census of Marine Life) The Pacific Ocean Shelf Tracking Program uses sound to track marine animals along the west coast of North America. Using hundreds of acoustic receivers (think of ears with computer hard drives attached) anchored to the sea floor, POST maintains listening lines running perpendicular to the coast, from shore to the edge of the continental shelf. The acoustic receivers record passing animals carrying acoustic tags, each one sending out a signal audible to the receivers. ... Tropical forests slashed for farmland - (Stanford University) A new study led by a Stanford researcher shows that more than 80 percent of the new farmland created in the tropics between 1980 and 2000 came from felling forests, which sends carbon into the atmosphere and drives global warming. But the research team also noted that big agribusiness has largely replaced small farmers in doing most of the tree cutting in Brazil and Indonesia, which may make it easier to rein in the trend.... University of Arizona-led group awarded $9.9 million to develop 'super rice' - (University of Arizona) Scientists seek to develop a rice strain that is better capable of withstanding drought and poorer soils and produces higher yields than current forms of domesticated rice.... NASA satellite sees Tropical Storm Kompasu transitioning over Korea and China - (NASA/Goddard Space Flight Center) NASA's Terra satellite captured the changing Tropical Storm Kompasu over Korea and China very early today, as it makes its way east to northern Japan.
