• How long will the world's uranium deposits last?

    At current consumption rates, the planet’s economically accessible uranium resources could fuel reactors for more than 200 years; further exploration and improvements in extraction technology are likely to at least double this estimate over time; if we extract uranium from seawater, and build breeder reactors, then supplies will last 30,000 to 60,000 years

  • NASA working on sonic boom-less jets

    Sonic booms are one of the major downsides of supersonic jets; they may not matter much over the battlefield, but are a hindrance in civilian aviation — the noise was sufficient to restrict the Mach-2 Concorde to subsonic speeds when over land

  • Advanced armor steel developed

    Super-strong military armor could be easier and less expensive to manufacture with a new steel-making process developed by a U.K. Ministry of Defense research facility

  • USDA's IG warns about flood of genetically modified crops

    Experts expect the number of genetically modified crops and traits, and the number of countries producing them, to double by 2015, raising the risks of imports of GM crops unknown to the USDA; worry centers on countries such as China, India, and Brazil where health and safety standards are more lax

  • Homeland security-related college courses bolster graduates' job chances

    There are now more than 150 academic institutions offering homeland security related undergraduate and graduate programs and degrees; this growth mirrors trends and needs in the job market

  • Smiths Detection shows active mm-wave detection system

    Passive mm-wave detection systems pick up the mm-wave heat energy emitted by the body, which is used as a background reference point; active systems transmit mm-wave into the detection area to boost the level of energy overall, give a better return and a more detailed image

  • Kansas wins $450 million biolab

    Kansas State University outlasted four other competitors to win the $450 million DHS National Bio- and Agro-Defense Facility

  • 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

  • Pair behind Chinese counterfeit computer components arrested

    Two California men arrested for illegally exporting sensitive technology to China; pair also accused of conspiring to purchase counterfeit electronic components for distribution in the U.S.

  • Soft power: CIA funded first Russian edition of Dr. Zhivago

    The Soviet authorities banned Boris Pasternak’s “Dr. Zhivago” because of its critical treatment of the 1917 revolution; the manuscript was smuggled to the West and published — but to be considered for the Noble Prize, a work of fiction must be published in its original language; the CIA steps in to fund publishing the Russian version of the book (in Holland) — allowing the Noble Prize committee to award Pasternak, and embarrass the USSR

  • Experts watch for Conficker superworm to be activated

    Conficker has infected at least 9 million computers; security experts anxiously wait for it to be activated; infection dwarfs the zombie army created by the infamous Storm worm, which reached a mere 1 million at its peak in September 2007

  • 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
