• New car-stopper uses squids' tentacle-based approach

    Looking for an answer to stop fleeing cars or suicide trucks hurtling toward their target, an Arizona company developed a tentacle-based device that ensnares the vehicle and brings it to a halt

  • Researchers develop silent UAVs

    UAVs are used more and more in surveillance and operational roles on the battlefield — and by the police; the larger UAVs are very noisy, announcing their presence and allowing the adversary to hide or escape; Georgia Institute of Technology researchers work on equipping UAVs with a “whisper” mode

  • ScanEagle offers and example of dual-use technology

    Initially developed to track dolphins and tuna from fishing boats in order to ensure “dolphin-safe” tuna in supermarkets, the ScanEagle UAV system has evolved into a mainstay with the U.S. Navy — and others as well

  • Top 7 alternative technologies to fossil fuel

    Energy expert says that an “all of the above” approach to the world’s energy problem is wrong; study shows wind and solar to be the most promising alternative technologies to fossil fuel; biofuel, clean coal, and nuclear power are do not hold such promise

  • Keeping water clean

    Researchers develop hydrogel material that can detect and remove contaminants in water; the hydrogel shrinks as it absorbs heavy metal pollutants, signaling the presence of cadmium and other toxic ions, even as it absorbs them from the contaminated water

  • U.K. military employs hovering droids in Afghanistan

    Hovering petrol-powered prowler patrols to check Afghan ambush alleys so soldiers do not have to; device may be used by law enforcement in urban areas — and future systems may carry weapons

  • Detecting rusted metal encased in concrete structures

    Many of the problems of aging infrastructure owe to rusting metal; trouble is, much of that metal is encased in concrete — in bridges, tunnels, dams, roads; new technology uses electromagnetic fields to measure corrosion through non-ferrous material

  • Israel uses new ISR systems, ordnance

    Advocates of air power were humbled in the 2006 Israel-Hezbollah war, but they hope to be vindicated in the Israel-Hamas conflict; Israel uses new ISR systems which shrink the sensor-to-shooter loop, and new bunker-busting ordnance

  • NIST's electromagnetic Phantom standardizes metal detector tests

    An electromagnetic phantom — a carbon and polymer mixture that simulates the human body — is being readied by NIST as a standardized performance test for walk-through metal detectors such as those used at airports

  • "Small is beautiful" comes to the nuclear power industry

    The main problem facing nuclear power is not the fear of accidents or terrorism, or anxiety about nuclear waste disposal; it is cost (it takes about $4,000/kilowatt to build a nuclear power station); there is a growing interest in small, tub-size nuclear power units

  • SwissCopter in $15 million Middle East deal

    Swiss developer of manned and unmanned systems for surveillance and search-and-rescue — and the innovative software these systems use — receives an order from an “unnamed Middle Eastern government”

  • Scientists seek ways to ward off killer asteroids

    The U.S. Congress has tasked a blue-ribbon panel of scientists with two missions: Find better ways to detect and deflect asteroids that might hit Earth; more than 5,000 near Earth objects, including 789 potentially hazardous objects, have been identified so far

  • Government examines, then dismisses, threat of gravitational waves

    A U.S. company solicited funds from the Defense Intelligence Agency to examine the threat to the United States from gravitational waves; the agency concludes that notions that these waves might pose a security threat “belong to the realm of pseudo-science, not science” (physicists say you did not need a 40-page report to reach this conclusion)

  • Blood-detecting clothing to help first responders, soldiers

    Wolverines researchers developed a yarn that can detect blood; clothing made from the yarn would be useful in high-risk professions, as unconscious firefighters, ambushed soldiers, or police officers in an accident may not be able to send a distress signal to a central command post

  • New surveillance system identifies suspicious, lost people

    New surveillance software will attempt to recognize whether a person on the street is acting suspiciously or appears to be lost; intelligent video cameras will be connected to large video screens and geo-referencing software to help law enforcement and security agencies
