• Exploring the Bermuda Triangle's swirling vortices

    Researchers, funded by the Office of Naval Research, deployed twenty-one underwater probes to study vortices at the Bermuda Triangle; a vortex is a swirl of water that can be created in several ways, including water being pushed between land masses and then released into the open ocean; the oceanographers did well to lose only one of the underwater probes, considering they were studying the notorious Triangle

  • 3-in-1 water monitoring system

    All water treatment plants using membrane technology are required to be able to perform three processes to comply with international standards: identify whether there are any bacteria or contaminants; detect any broken membrane filters in the treatment plant; and pinpoint which filter is broken — accurate to 1 in 100,000 filters; a new, innovative device performs all three processes

  • For safer offshore drilling, government should modify monitoring practices

    Since the April 2010 Deepwater Horizon blowout and explosion, the federal government as well as the offshore oil and gas industry have been undergoing major changes, including the issuance of regulations requiring operators of offshore facilities to adopt and implement comprehensive Safety and Environmental Management System (SEMS) programs by 15 November 2011

  • Nuclear waste repositories in suburbia?

    Finding sites for nuclear waste storage is a growing problem, with decision makers running into the “not in my back yard” problem; the demise of Nevada’s Yucca Mountain project is but the latest example; researchers find that acceptance of sites for spent nuclear fuel repository may well depend on gender and economic background: in Finland, at least, affluent men more often are more receptive to the idea of locating such facilities near their neighborhoods than women or disadvantaged people

  • Automated pavement crack detection and sealing system to extend roadways life

    Researchers from the Georgia Tech Research Institute developed a prototype automated pavement crack detection and sealing system; in road tests, the system was able to detect cracks smaller than one-eighth-inch wide and efficiently fill cracks from a vehicle moving at a speed of three miles per hour

  • New method uses gunshot residue to determine caliber, type of weapon used in crime

    Researchers have developed a method to determine the caliber and type of weapon used in a crime by analyzing gunshot residue (GSR); using near-infrared (NIR) Raman microspectroscopy and advanced statistics, the new technique may play a pivotal role in law enforcement cases and forensic investigations

  • Belief in hell associated with reduced crime

    A broad study, study following143,197 people in sixty-seven countries over twenty-six years, found that criminal activity is higher in societies in which people’s religious beliefs contain a strong punitive component than in places where religious beliefs are more benevolent; a country where many more people believe in heaven than in hell is likely to have a much higher crime rate than one where these beliefs are about equal

  • Knee-strapped power harvester to do away with batteries

    Battery-powered devices may soon be a thing of the past; researchers have created an innovative energy harvester to power some of the latest wearable gadgets; the energy harvester, strapped to the knee joint, converts knee motions into energy

  • New device allows users to scale walls, mountain faces

    A group of mechanical and aerospace engineering students, using engineering principles, basic math, and ingenuity, have designed a system which would enable special operations force personnel, first responders, and members of search and rescue teams to scale buildings or mountain faces under a variety of conditions

  • Seabed carpet could harness wave energy

    A synthetic “seabed carpet” that mimics the wave-damping effect of a muddy seafloor could be used to extract energy from waves passing over it. As well as offering a new way to produce clean and cheap electricity, the carpet — which has not yet been built — could be used to protect coastal areas against strong waves and provide areas of safe haven for boats in stormy seas

  • Knowledge of fractions and long division predicts long-term math success

    From factory workers to Wall Street bankers, a reasonable proficiency in math is a crucial requirement for most well-paying jobs in a modern economy; yet, over the past thirty years, mathematics achievement of U.S. high school students has remained stagnant — and significantly behind many other countries, including China, Japan, Finland, the Netherlands, and Canada; a new study has identified a major source of the gap — U. S. students’ inadequate knowledge of fractions and division

  • Key to U.S. future prosperity: world-class research universities

    American research universities are essential for U.S. prosperity and security, but the institutions are in danger of serious decline unless the federal government, states, and industry take action to ensure adequate, stable funding in the next decade, says a new report by the National Research Council; “The talent, innovative ideas, and new technologies produced by U.S. research universities have led to some of our finest national achievements, from the modern agricultural revolution to the accessibility of the World Wide Web,” says the chairman of the committee that wrote the report

  • Explaining extreme months

    Two months in Midwest history — March 2012 and December 1889 — stand out as the warmest winter months in more than a century of weather records; scientists investigated why these months, separated by 123 years, were so exceptional

  • Laser beams shine light on nature’s extreme events

    “Extreme” events in nature, such as hurricanes, tsunamis and bushfires, may be more commonplace and predictable than you might think; researchers are using lasers to study how frequently extreme events happen, and their work highlights that in nature, “extreme” does not have to mean “rare”

  • Quick-curing concrete for infrastructure, mining disaster recovery

    A quick-curing concrete can be sprayed to reinforce structures — buildings, runways, tunnels, bridges, dams – damaged by an act of terror or natural disaster; the spraying can be done almost immediately, before the structure fails catastrophically, providing safety for rescue workers who risk their lives minutes after disasters hit, and for still stranded in or near the damaged structure
