Climate scientists talk hurricanes, drought, with capitol staffers over lunch - (The Earth Institute at Columbia University) Climate change has become a divisive topic in America. To shift the focus back on science, scientists from Columbia University are briefing members of Congress and their staff during the second annual Climate Science Day on Capitol Hill. Climate Science Day, organized by a range of national scientific organizations, gives scientists a chance to share their expertise with political leaders on climate-related topics such as hurricanes, drought and sea-level rise, and to convey the importance of fundamental climate research.... What really happened prior to 'Snowball Earth'? - (University of Miami Rosenstiel School of Marine & Atmospheric Science) In a study published in the journal Geology, Dr. Peter Swart if the University of Miami Rosenstiel School of Marine and Atmospheric Science suggests that the large changes in the carbon isotopic composition of carbonates which occurred prior to the major climatic event more than 500 million years ago, known as "Snowball Earth," are unrelated to worldwide glacial events.... MSU researchers show how new viruses evolve, and in some cases, become deadly - (Michigan State University) In the current issue of Science, researchers at Michigan State University demonstrate how a new virus evolves, which sheds light on how easy it can be for diseases to gain dangerous mutations.... Researchers show how viruses evolve, and in some cases, become deadly - (National Science Foundation) Researchers at Michigan State University have demonstrated how a new virus evolves, shedding light on how easy it can be for diseases to gain dangerous mutations. The findings appear in the current issue of the journal Science.... Commentary in Nature: Can economy bear what oil prices have in store? - (University of Washington) The economic pain of a flattening oil supply will trump the environment as a reason to curb the use of fossil fuels, say two scientists, one from the University of Washington and one from the University of Oxford in the United Kingdom, in the Jan. 26 issue of the journal Nature.... NASA satellites see cyclone Funso exiting Mozambique Channel - (NASA/Goddard Space Flight Center) Powerful Cyclone Funso is now beginning to exit the Mozambique Channel, and NASA's Aqua satellite captured a stunning image of the storm that shows the depth and extent of it.... NASA infrared satellite instrument sees tropical storm Iggy growing in strength - (NASA/Goddard Space Flight Center) The AIRS infrared instrument that flies on NASA's Aqua satellite has been providing forecasters with the cloud top temperatures in the Southern Indian Ocean's ninth tropical cyclone, which has officially been renamed Iggy. AIRS data showed that the area of strong thunderstorms around Iggy's center has expanded in area over the last day.... Detecting detrimental change in coral reefs - (NASA/Goddard Space Flight Center) Phil Dunstan has watched reefs deteriorate at an alarming rate. Recently he has found that the Landsat Satellite data offers a way to evaluate these changes globally. Using an innovative way to map how coral reefs are changing over time, Dustan now can find 'hotspots' where conservation efforts should be focused to protect these delicate communities.... Cell Press launches a new open-access journal, Cell Reports - (Cell Press) Cell Press reinforces its commitment to provide a broad range of publishing options for the life sciences community with the inaugural issue of a new open-access journal: Cell Reports. Since the announcement in August, after six months of hard work on the part of our authors, reviewers, and editorial board members as well as our own editorial and production teams, the first issue is available online today, Jan. 26, 2011, with eight exciting papers on topics ranging from evolutionary biology to immunology.... Living on the edge: An innovative model of mangrove-hammock boundaries in Florida - (University of Miami) University of Miami Ecologist Donald L. DeAngelis, who is also a researcher for the US Geological Survey, has worked with collaborators to develop a novel computer model describing how future hurricanes and sea level rise may trigger changes to South Florida's native coastal forests.... How seawater could corrode nuclear fuel - (University of California - Davis) Japan used seawater to cool nuclear fuel at the stricken Fukushima-Daiichi nuclear plant after the tsunami in March 2011 -- and that was probably the best action to take at the time, says Professor Alexandra Navrotsky at UC Davis. But Navrotsky and others have since discovered a new way in which seawater can corrode nuclear fuel, forming uranium compounds that could potentially travel long distances, either in solution or as very small particles.... LITHOSPHERE Highlights: February 2012 - (Geological Society of America) he new issue of LITHOSPHERE is online now. Papers present evidence for the on-going re-shaping of the Rocky-Mountain-Colorado Plateau region by young uplift driven from below (mantle buoyancy), research in the Aegean Sea that documents a newly defined extensional fault system, and study of the hydrologic heterogeneity of faulted and fractured sediment layers with implications for similar rocks to affect the flow of moisture downward toward the spent nuclear fuel geologic repository at Yucca Mountain.... New GEOLOGY articles online Jan. 23 - (Geological Society of America) New GEOLOGY articles posted ahead of print examine the role of climate warming in the Permian-Triassic mass extinction, documentation of one of the first examples of land-based magnetic lineations similar to those that characterize sea-floor spreading centers, evidence that the disappearance of the Indus Valley Civilization around 2000 BC may be linked to a rearrangement of river drainage systems, fossil trees from the Cretaceous that reveal the true magnitude of past climate warmth, and more.... Life beyond Earth? Underwater caves in Bahamas could give clues, says Texas A&M marine expert - (Texas A&M University) Discoveries made in some underwater caves by Texas &M University at Galveston researchers in the Bahamas could provide clues about how ocean life formed on Earth millions of years ago, and perhaps give hints of what types of marine life could be found on distant planets and moons.... Viruses con bacteria into working for them - (Massachusetts Institute of Technology, Department of Civil and Environmental Engineering) MIT researchers have discovered that certain photosynthetic ocean bacteria need to beware of viruses bearing gifts. These viruses are really con artists carrying genetic material taken from their previous bacterial hosts that tricks the new host into using its own machinery to activate the genes, a process never before documented in any virus-bacteria relationship. The con occurs when a grifter virus injects its DNA into a bacterium living in a phosphorus-starved region of the ocean.... Does antimatter weigh more than matter? - (University of California - Riverside) Does antimatter weigh more than matter? UC Riverside physicists want to know. Their finding could explain why the universe seems to have no antimatter and why it is expanding at an ever increasing rate. In the lab, the researchers took the first step towards measuring the free fall of positronium -- a bound state between a positron and an electron. They separated the positron from the electron long enough to measure gravity's effect on them.... Iowa State engineer wants to 'sculpt' more powerful electric motors and generators - (Iowa State University) Iowa State University's Dionysios Aliprantis is developing several technologies that could improve the performance of electric motors and generators. And that could make a real difference in building sustainable energy systems.... Radical theory explains the origin, evolution, and nature of life, challenges conventional wisdom - (Case Western Reserve University) The Earth is alive, asserts a revolutionary scientific theory of life emerging from Case Western Reserve University School of Medicine. The trans-disciplinary theory demonstrates that purportedly inanimate, non-living objects -- for example, planets, water, proteins, and DNA -- are animate, that is, alive. With its broad explanatory power, applicable to all areas of science and medicine, this novel paradigm aims to catalyze a veritable renaissance.... European Geosciences Union General Assembly, April 22-27, 2012, Vienna, Austria - (European Geosciences Union) Journalists, science writers, and public information officers can now register online to the 2012 General Assembly of the European Geosciences Union.
