• Examination of Finnish lakes reveals radiation secrets

    A new study casts doubt over the validity of models used to assess the impact of radiation on human health; an examination of the affects of radioactive fallout from the 1986 Chernobyl accident on two Finnish lakes sows that the transfer of the radioactive compounds is non-linear, and that the levels of radioactive compounds appear to be three times higher in fish-eating species (piscivores) than in non-fish-eating species

  • A second look at off-shore use of vertical-axis wind turbines

    Wind energy researchers are re-evaluating vertical axis wind turbines (VAWTs) to help solve some of the problems of generating energy from offshore breezes; though VAWTs have been around since the earliest days of wind energy research, VAWT architecture could transform offshore wind technology

  • Radiation detection equipment installed in four Mexican ports

    The Megaports Initiative is a U.S. Department of Energy program intended to enhance the ability of ports around the world to detect and interdict illicit shipments of special nuclear and other radioactive materials; Under the initiative, radiation detection gear and protocols were implemented in the Mexican ports of Manzanillo, Altamira, Lazaro Cardenas, and Veracruz, through which 92 percent of Mexico’s containerized cargo pass

  • Raytheon's Space Fence technology tracks space debris

    Space debris threatens systems the U.S. military and economy depend on every day, including satellites that power navigation, weather and critical infrastructures; the Space Fence program is capable of detecting more and much smaller objects in low earth orbit

  • Measuring DHS effectiveness monitoring chemical plant safety standards

    The events of 9/11 triggered a national re-examination of the security of facilities that use or store hazardous chemicals in quantities which, in the event of a terrorist attack, could put large numbers of Americans at risk of serious injury or death; the GAO issued a report on how DHS ensures compliance with chemical facilities security standards

  • Surface coal mining destroying West Virginia streams, rivers

    More than 22 percent of streams and rivers in southern West Virginia have been degraded to the point they may now qualify as impaired under state criteria; the substantial losses in aquatic insect biodiversity and increases in salinity is linked to sulfates and other pollutants in runoff from mines often located miles upstream

  • Conflict of interests charges surround two pro-fracking studies

    Two recent studies — by research institutes at  the University of Buffalo and the University of Texas — on the relationship between fracking and the contamination of groundwater, offered what was claimed to be scientific, peer-reviewed research which concluded that fracking does not contribute to such contamination; an examination of the two reports reveals that they were not properly reviewed according to accepted academic standards, and that their authors, and the research institutes which sponsored them, are heavily involved with companies which conduct fracking operations; the author of the University of Texas report sits on the board of a leading fracking company, where his compensation is more than twice as large as his UT salary; he did not disclose this fact in the study — or inform UT of this connection; UT is investigating

  • The five biggest stories at Black Hat

    The annual Black Hat Briefings conference, held last week in Las Vegas, is the world’s biggest, and arguably the most important, gathering of security researchers; here are the five biggest stories to take away from last week’s Black Hat meeting in Las Vegas

  • Science group: storing spent nuclear fuel in dry casks significantly safer then wet pools storage

    An NRC report on the lessons of the Fukushima disaster says that storing spent nuclear fuel in wet pools is “adequate” to protect the public; a science groups says there is a significantly safer way to store the 55,000 tons of radioactive waste currently stored by the 104 nuclear power plants operating in the United States: transferring the spent fuel to dry casks

  • Global warming unequivocal in its advance, says NCAA expert

    Global warming is unequivocal in its advance and will lead to more record-setting temperatures, says Warren Washington, a senior scientist at the National Center for Atmospheric Research; in a talk at Sandia Lab, Washington presented graph after graph showing how various atmospheric processes have combined to create stronger rainfall near the equator and more intense droughts in the subtropics, as well as sea-level rises and increased storm surges

  • Predictions by climate models are flawed, says MIT meteorology expert

    Massachusetts Institute of Technology professor Richard Lindzen, a global warming skeptic, says that too much is being made of climate change by researchers seeking government funding; he said their data and their methods did not support their claims; for thirty years, climate scientists have been “locked into a simple-minded identification of climate with greenhouse-gas level. That climate should be the function of a single parameter (like CO2) has always seemed implausible. Yet an obsessive focus on such an obvious oversimplification has likely set back progress by decades,” Lindzen said

  • Large, magnitude 8 earthquakes hit New Zealand with regularity

    A new study finds that very large earthquakes have been occurring relatively regularly on the Alpine Fault along the southwest coastline of New Zealand for at least 8,000 years

  • Studying the physics of avalanches

    Snow avalanches, a real threat in countries from Switzerland to Afghanistan, are fundamentally a physics problem: What are the physical laws that govern how they start, grow, and move, and can theoretical modeling help predict them? New study offers answers

  • Game lets players try their hand at computer security

    A new game — Control-Alt-Hack — gives teenage and young-adult players a taste of what it means to be a computer-security professional defending against an ever-expanding range of digital threats; the game’s creators will present it this week in Las Vegas at Black Hat 2012; educators in the continental United States can apply to get a free copy of the game while supplies last; it is scheduled to go on sale in the fall for a retail price of about $30

  • Northrop Grumman delivers Nationwide AIS to Coast Guard

    Northrop Grumman has delivered its Nationwide Automatic Identification System (AIS) to the Coast Guard; the system provides a more comprehensive view of vessels bound for and navigating within U.S. ports and waterways
