Earth Sciences RSS FeedsPenn researchers uncover a mechanism to explain dune field patterns - (University of Pennsylvania) In a study of the harsh but beautiful White Sands National Monument in New Mexico, University of Pennsylvania researchers have uncovered a unifying mechanism to explain dune patterns. The new work represents a contribution to basic science, but the findings may also hold implications for identifying when dune landscapes like those in Nebraska's Sand Hills may reach a "tipping point" under climate change, going from valuable grazing land to barren desert....Feed Source: www.eurekalert.org NASA satellite sees cyclone Jasmine heading for Vanuatu, New Caledonia - (NASA/Goddard Space Flight Center) NASA's Aqua satellite passed over strengthening Tropical Storm Jasmine and noticed bands of thunderstorms wrapping into its center as it heads toward Vanuatu and New Caledonia.... NASA watches a Gulf Weather system for unusual subtropical development - (NASA/Goddard Space Flight Center) Hurricane season in the Atlantic Ocean and Gulf of Mexico doesn't begin until June 1, 2012, but a low pressure area in the Gulf called System 90L, is being watched on Feb. 5 and 6 for possible development into sub-tropical depression although the chances are now slim to none. Data from the GOES-13 satellite was created into an image at NASA, and it showed System 90L raining on south Florida today.... NASA's Aqua satellite sees small new tropical storm near Tonga - (NASA/Goddard Space Flight Center) Tropical Storm 11P has formed in the South Pacific Ocean, and NASA's Aqua satellite captured an infrared image of its cloud temperatures, revealing power in the cyclone.... Fair to bring future scientists and engineers to UC Riverside - (University of California - Riverside) What are you really eating when you’re eating chicken? Do different types of wood produce the same heat when burned? Do twins have similar fingerprints? How does sleep affect your memory? Does your eye color matter? Hundreds of K-12 students from 33 local schools will answer these and other intriguing questions at the 23nd annual Science and Engineering Fair at the University of California, Riverside, Feb. 7-9.... Domestic cats, and wild bobcats and pumas, living in same area have same diseases - (National Science Foundation) The joint National Science Foundation and National Institutes of Health Ecology and Evolution of Infectious Diseases Program funded the study. Scientists at Colorado State University and other institutions conducted the research. It provides evidence that domestic cats and wild cats that share the same outdoor areas in urban environments also can share diseases such as Bartonellosis and Toxoplasmosis. Both can be spread from cats to people.... Global extinction: Gradual doom as bad as abrupt - (National Science Foundation) Thomas Algeo, a geologist at the University of Cincinnati, and 13 colleagues have produced a high-resolution look at the geology of a Permian-Triassic boundary section on Ellesmere Island in the Canadian Arctic.... UNH ocean scientists shed new light on Mariana Trench - (University of New Hampshire) An ocean mapping expedition has shed new light on deepest place on Earth, the 2,500-kilometer long Mariana Trench in the western Pacific Ocean near Guam. Using a multibeam echo sounder, state-of-the-art equipment for mapping the ocean floor, scientists from the University of New Hampshire Center for Coastal and Ocean Mapping/Joint Hydrographic Center found four "bridges" spanning the trench and measured its deepest point with greater precision than ever before.... Navy to begin tests on electromagnetic railgun prototype launcher - (Office of Naval Research) The Office of Naval Research's Electromagnetic Railgun program will take an important step forward in the coming weeks when the first industry railgun prototype launcher is tested at a facility in Dahlgren, Va., officials said Feb. 6. The long-range weapon fires projectiles using electricity instead of chemical propellants. Magnetic fields created by high electrical currents accelerate a sliding metal conductor, or armature, between two rails to launch projectiles at 4,500 mph to 5,600 mph.... More environmental rules needed for shale gas, says Stanford geophysicist - (Stanford University) In his State of the Union address, President Barack Obama praised the potential of the country's tremendous supply of natural gas buried in shale. But the "Halliburton exclusion" passed by Congress says gas companies don't have to disclose the chemicals used in fracturing fluids. That was a real mistake because it makes the public needlessly paranoid, says Stanford geophysicist Mark Zoback.... Researchers examine consequences of non-intervention for infectious disease in African great apes - (University of California - Santa Barbara) Infectious disease has joined poaching and habitat loss as a major threat to the survival of African great apes as they have become restricted to ever-smaller populations. Despite the work of dedicated conservationists, efforts to save our closest living relatives from ecological extinction are largely failing, and new scientific approaches are necessary to analyze major threats and find innovative solutions.... Political leaders play key role in how worried Americans are by climate change - (Ohio State University) More than extreme weather events and the work of scientists, it is national political leaders who influence how much Americans worry about the threat of climate change, new research finds. In a study of public opinion from 2002 to 2010, researchers found that public belief that climate change was a threat peaked in 2006-2007 when Democrats and Republicans in Congress showed the most agreement on the issue.... What drives public opinion on climate change? - (Springer) The researchers reveal that the driving factor that most influences public opinion on climate change is the mobilizing efforts of advocacy groups and elites. The study conducted an empirical analysis of the factors affecting US public concern about the threat of climate change between January 2002 and December 2010. The five factors that were examined were extreme weather events, public access to accurate scientific information, media coverage, elite cues and movement/countermovement advocacy.... New methodology assesses risk of scarce metals - (Yale University) Yale researchers have developed a methodology for governments and corporations to determine the availability of critical metals, according to a paper in Environmental Science & Technology.... Established journal Evolutionary Applications to publish under open-access model - (Wiley-Blackwell) Wiley-Blackwell, the scientific, technical, medical and scholarly publishing business of John Wiley & Sons Inc., today announced that Evolutionary Applications has joined the Wiley Open Access publishing program. All newly published articles in the journal will be open access and free to view, download and share for non-commercial use.... Invasive alien predator causes rapid declines of European ladybirds - (Centre for Ecology & Hydrology) A new study provides compelling evidence that the arrival of the invasive non-native harlequin ladybird to mainland Europe and subsequent spread has led to a rapid decline in historically-widespread species of ladybird in Britain, Belgium and Switzerland.The analysis, published today in the scientific journal Diversity and Distributions, is further evidence that harlequin ladybirds are displacing some native ladybirds, most probably through predation and competition.... A bug's (sex) life: Diving beetles offer unexpected clues about sexual selection - (University of Arizona) Studies of diving beetles suggest sperm evolution may be driven by changes in female reproductive organs, challenging the paradigm of post-mating sexual selection being driven mostly by competition among sperm. In the process, the researchers discovered an unexpected and stunning variety of sperm form and behavior.... Fossil cricket reveals Jurassic love song - (University of Bristol) The love song of an extinct cricket that lived 165 million years ago has been brought back to life by scientists at the University of Bristol. The song - possibly the most ancient known musical song documented to date - was reconstructed from microscopic wing features on a fossil discovered in North East China. It allows us to listen to one of the sounds that would have been heard by dinosaurs and other creatures roaming Jurassic forests at night.... Tree rings may underestimate climate response to volcanic eruptions - (Penn State) Some climate cooling caused by past volcanic eruptions may not be evident in tree-ring reconstructions of temperature change because large enough temperature drops lead to greatly shortened or even absent growing seasons, according to climate researchers, who compared tree-ring temperature reconstructions with model simulations of past temperature changes.... Land-cover changes do not impact glacier loss - (University of Innsbruck) A new study shows that land-cover changes, in particular deforestation, in the vicinity of glaciers do not have an impact on glacier loss. However, the study, in which Innsbruck climate researcher were directly involved, also shows that deforestation decreases precipitation in mid elevation zones, which affects the quality of life of the population living in the surrounding areas. The study is published online in Nature Climate Change on Feb. 5 2012.... University of Miami student Bignami among 5 Guy Harvey Scholarship recipients - (University of Miami Rosenstiel School of Marine & Atmospheric Science) University of Miami Rosenstiel School of Marine & Atmospheric Science graduate student Sean Bignami received a Guy Harvey Ocean Foundation scholarship for his studies of how the changing chemistry of marine waters as a result of ocean acidification might affect the early development of large marine fish.... AIBS names emerging public policy leaders - (American Institute of Biological Sciences) The American Institute of Biological Sciences has selected two graduate students to receive the 2012 AIBS Emerging Public Policy Leadership Award.
