• California’s hydropower is vulnerable to climate change

    Fifteen percent of California’s electricity comes from hydropower, a cheap and relatively clean energy source; .about 75 percent of this hydropower comes from high-elevation units, located above 1,000 ft.; with most of them located in Northern California and the Sierra Mountains; if California loses snowpack under climate warming, these high-elevation reservoirs might not be able to store enough water for hydropower generation in summer months when the demand is much higher

  • Dropping lake levels in Michigan are a cause for concern

    In a state that boasts 11,000 lakes, Michigan is going through a year long drought that has residents and businesses scrambling as water levels continue to decrease; the low waters is the result of low snowpack last winter and a hot dry summer this year

  • Improved disaster resilience is imperative for U.S: report

    A new report from the National Academies says that it is essential for the United States to bolster resilience to natural and human-caused disasters, and that this will require complementary federal policies and locally driven actions that center on a national vision – a culture of resilience; improving resilience should be seen as a long-term process, but it can be coordinated around measurable short-term goals that will allow communities better to prepare and plan for, withstand, recover from, and adapt to adverse events

  • Seeing through walls with the help of laser systems

    Inspired by the erratic behavior of photons zooming around and bouncing off objects and walls inside a room, researchers combined these bouncing photons with advanced optics to enable them to “see” what is hidden around the corner

  • UAVs with dexterous arms to help in infrastructure repair and disaster recovery

    With current technology, most UAVs perform passive tasks such as surveillance and reconnaissance missions, tasks which are performed well above ground; researchers are interested in how UAVs might interact with objects at or near ground level; a UAV with dexterous arms could perform a wide range of active near-ground missions, from infrastructure repair and disaster recovery to border inspection and agricultural handling

  • Extreme summer heat events, global warming linked: research

    Since the late 1980s researches have been asserting that global warming would reach a point in the coming decades when its connection to extreme events would become more apparent; while some warming should coincide with a noticeable boost in extreme events, the natural variability in climate and weather can be so large as to disguise the trend; to distinguish the trend from natural variability, NASA researchers turned to statistics; the researchers did not focus on the causes of temperature change, analyzing instead surface temperature data

  • Study finds correlation between injection wells and small earthquakes

    Most earthquakes in the Barnett Shale region of North Texas occur within a few miles of one or more injection wells used to dispose of wastes associated with petroleum production such as hydraulic fracturing fluids, according to new research

  • Study finds substantial water pollution risks from fracking

    The Marcellus Shale region covers approximately 124,000 square kilometers from New York to West Virginia and is being intensely developed; a new study finds that the disposal of contaminated wastewater from hydraulic fracturing — commonly known as fracking — wells producing natural gas in the Marcellus Shale region poses substantial potential risks of river and other water pollution

  • Seeing through walls, clearly

    Research and tests show, for the first time, the ability to use t passive WiFi radar for through-the-wall (TTW) detection of moving personnel – and do so covertly

  • New forensic tool automates RAM forensic investigations

    New tool enables computer forensic investigators to analyze and make use of information contained in volatile memory; memory analysis produces important, case-relevant data for investigators that cannot be obtained from disk analysis, such as running applications, open files, and active network connections

  • Canadian company offers the first treatment to neutralize red mud

    Red mud is the most significant waste product of the traditional Bayer process for aluminum production; the industry produces more than 100 million tons of red mud a year, of which less than 5 percent is be reused; the rest is stored in ponds and reservoirs, posing serious environmental and economic risk; on 4 October 2010, for example, a flood of toxic red mud devastated Hungary after a retaining dyke ruptured, causing an ecological disaster; Canadian company Orbite Aluminae offers a technology to tackle the aluminum industry’s most serious problem

  • Improving landmine detection – and air travel safety

    It is estimated that there are about 110 million active landmines lurking underground in sixty-four countries across the globe; each year as many as 25,000 people, most of them civilians, are maimed or killed by landmines; the mines not only kill and maim, they can paralyze communities by limiting the use of land for farming and roads for trade; researchers offer a better way to detect landmines – a method which can also be used in airports to help thwart possible terrorist threats

  • Forget blizzards and hurricanes, heat waves are deadliest

    Tornadoes, blizzards, and hurricanes get most of our attention because their destructive power makes for imagery the media cannot ignore; for sheer killing power, however, heat waves do in far more people than even the most devastating hurricane; Hurricane Katrina and its floods, which devastated New Orleans and the Gulf Coast in 2005, exacted a death toll of 1,836 people; the heat wave which enveloped Europe during the course of three excruciating weeks in August 2003 of that year, killed an estimated 70,000 people

  • Improving oil recovery, aiding environmental cleanup

    Researchers have taken a new look at an old, but seldom-used technique developed by the petroleum industry to recover oil, and learned more about why it works, how it could be improved, and how it might be able to make a comeback not only in oil recovery but also environmental cleanup

  • Federal mapping tool used in Gulf spill expanded to Arctic

    A new federal interactive online mapping tool used by emergency responders during the Deepwater Horizon oil spill has been expanded to include the Arctic, and will help address numerous challenges in the Arctic posed by increasing ship traffic and proposed energy development
