• California worried about its own extreme weather

    California will not see a superstorm like Hurricane Sandy because the Pacific Ocean is too cold to feed that kind of weather system, but researchers monitoring precipitation and snowpack say weather can have comparable effects

  • Sandy in perspective

    Hurricane Sandy has left death and destruction in its path, and it broke a few records, but there were worse hurricanes; since 1900, 242 hurricanes have hit the United States; if Sandy causes $20 billion in damage, in 2012 dollars, it would rank as the seventeenth most damaging hurricane or tropical storm out of these 242; the Great Miami Hurricane of 1926 tops the list; Hurricane Katrina ranks fourth; from August 1954 through August 1955, the East Coast saw three different storms make landfall — Carol, Hazel, and Diane; each, in 2012, would have caused about twice as much damage as Sandy

  • Sea levels are rising ahead of predictions; scientists explain why

    The last official Intergovernmental Panel on Climate Change (IPCC) report in 2007 projected a global sea level rise between 0.2 and 0.5 meters by the year 2100; current sea-level rise measurements meet or exceed the high end of that range and suggest a rise of one meter or more by the end of the century; scientists meeting next week at the Geological Society of America annual meeting will discuss whether estimates of the rate of future sea-level rise are too low

  • Flying robot avoids obstacles

    Researchers have created an autonomous flying robot which is as smart as a bird when it comes to maneuvering around obstacles; able to guide itself through forests, tunnels, or damaged buildings, the machine could have tremendous value in search-and-rescue operations

  • Experts: German nuclear exit offers economic, environmental benefits

    Following the accident at the Fukushima Daiichi Nuclear Power Station in 2011, the German government took the nation’s eight oldest reactors offline immediately and passed legislation which will close the last nuclear power plant by 2022; this nuclear phase-out had overwhelming political support in Germany; elsewhere, many saw it as “panic politics”; a new collection of studies shows that the nuclear shutdown and an accompanying move toward renewable energy are already yielding measurable economic and environmental benefits

  • Quick-cook method turns algae into oil

    It looks like Mother Nature was wasting her time with a multimillion-year process to produce crude oil; University of Michigan engineering researchers can “pressure-cook” algae for as little as a minute and transform an unprecedented 65 percent of the green slime into biocrude

  • Rising sea levels make NYC vulnerable to more frequent, more intense floods

    Scientists say that Hurricane Sandy has forced a recognition on New York City and on other coastal communities: the steady rise in sea levels means not only more floods, but more frequent and more devastating floods; three of the top 10 highest floods at the Battery since 1900 happened in the last two and a half years; after rising roughly an inch per decade in the last century, coastal waters in New York are expected to climb as fast as six inches per decade, or two feet by midcentury; the city is exploring a $10 billion system of surge barriers and huge sea gates

  • Study connects burning fossil fuels to sea level rise

    A study has found that burning all the Earth’s reserves of fossil fuels could cause sea levels to rise by as much as five meters — with levels continuing to rise for typically 500 years after carbon dioxide emissions ceased

  • "Stutter jump" could improve performance of search and rescue robots

    A new study shows that jumping can be much more complicated than it might seem; in research that could extend the range of future rescue and exploration robots, scientists have found that hopping robots could dramatically reduce the amount of energy they use by adopting a unique two-part “stutter jump”

  • DOD faces shortfall in quality STEM workers; overhaul of recruitment policies needed

    The principal challenge for the U.S. Department of Defense’s science, technology, engineering, and mathematics (STEM) work force is recruiting and retaining top quality professionals for critical positions, says a new report; the agency must become — and be perceived as — an appealing career destination for the most capable scientists, engineers, and technicians, all of whom are in great demand in the global marketplace

  • Leading U.S., U.K. scientists condemn conviction of Italian earthquake scientists

    A judge in Italy last week sentenced six Italian seismologists and a former government official to six years in prison over the deadly 6 April 2009 earthquake in L’Aquila. The seven defendants were found guilty of manslaughter; Ralph J. Cicerone, president of the U.S. National Academy of Sciences, and Sir Paul Nurse, president of the U.K. Royal Society, issued the following statement

  • Improving high-speed rail ties against freezing, thawing conditions

    Research project is helping high-speed rail systems handle the stress of freezing and thawing weather conditions; the 3-year study looks at the freeze-thaw durability of concrete railroad ties; the research is essential to developing safe and durable high-speed rail systems

  • Researchers invent safe wireless vehicle charging technology

    Researchers have invented a safe, efficient technology wirelessly to charge electric vehicles using “remote magnetic gears” — a rotating base magnet driven by electricity from the grid, and a second located within the car — and successfully tested it on campus service vehicles

  • A coal economy has multiple health, social risks, says major review

    A major review of evidence on the impact of coal mining has highlighted serious, ongoing health and social problems, and an urgent need for improvements in government coal mining policy

  • USGS: Sandy will erode many Atlantic Coast beaches

    Nearly three quarters of the coast along the Delmarva Peninsula is very likely to experience beach and dune erosion as Hurricane Sandy makes landfall, while overwash is expected along nearly half of the shoreline; the predictions of coastal change for the Delaware, Maryland, and Virginia peninsula is part of a larger assessment of probable coastal change released by the U.S. Geological Survey (USGS)
