• Seabed cable signals to sense tsunamis

    The current tsunami warning system relies on a global seismometer network to detect earthquakes that may indicate that a tsunami has formed; deep-ocean pressure sensors and coastal tide gauges are the only tools available to detect and measure an actual tsunami; the electric current induced in submarine cables may provide an additional way to confirm and track a tsunami; researchers suggest monitoring voltages changes across the vast network of communication cables on the seabed to enhance the current tsunami warning system

  • Gordon Brown: U.K. airports to get whole-body scanners next week

    The U.K. prime minister said that beginning next week, whole-body scanners will be deployed at U.K. airports; in addition to backscatter X-rays and millimeter wave systems, Brown hinted that the government would seek to deploy terahertz technology

  • India awards Implant Sciences $6 million contract for sniffer

    India will deploy the company’s explosive detector – the Quantum Sniffer QS-H150 – for protection of military and civilian facilities; the sniffer comes with a large substance library which includes not only standard military and commercial explosives, but also a wide variety of improvised and homemade explosives (IEDs and HMEs)

  • Discrimination warning over U.K. airport body scanners

    U.K. equality watchdog wrote U.K. home secretary to say it was “concerned that that the proposals to introduce body scanners are likely to have a negative impact on individuals’ rights to privacy, especially members of particular groups including disabled people, older people, children, transgendered people, women and religious groups”

  • Montana airport wants private security companies to replace TSA screeners after breach

    TSA screeners at Gallatin Field in southwest Montana failed to detect a gun in a passenger’s carry-on bag; the airport security authorities say they will explore private companies to replace TSA screeners; chair of the Gallatin Airport Authority: “If those guys can’t detect a handgun, which is pretty basic, not some exotic explosive sewn to your underpants, then we get upset”

  • Scientists cautiously optimistic as Doomsday clock reset

    The minute hand of the Bulletin of Atomic Scientists’ Doomsday clock was moved back one minute – to seven minutes to midnight – to indicate a slight improvement in the world’s nuclear weapons situation; midnight on the clock signifies the apocalypse, and the minute hand symbolizes the countdown to disaster

  • Bruker’s Autonomous Rapid Facility Chemical Agent Monitor advances to DHS Phase IIIb

    Bruker uses its proprietary RAID Ion Mobility Spectrometry (IMS) technology for the Autonomous Rapid Facility Chemical Agent Monitor Program, which is designed for long-term monitoring of ambient air for the presence of hazardous chemical vapors in the interior or exterior of critical government buildings, subways, airports and other facilities; the company says it has also developed a new product – the DE-tector — which uses next-generation IMS technology with selectivity and specificity that approaches that of mass spectrometry

  • Hidden sensor network detects explosives

    German researchers develop a covert sensor system that track people carrying explosive in busy transportation hubs; the system works using two separate sensory networks that gather chemical and kinetic information — the first is made up of a series of four to six rotating laser scanners that send pulses through corridors, walkways, or escalators at airports or railway stations; the second network consists of electronic sensors hidden in air vents and wall fixtures that provide chemical data on explosive materials

  • U.K. firm says its scanning technology meets security, privacy concerns

    Cambridge, U.K.-based TeraView says it is developing terahertz body scanners which use light from upper end of the infra-red spectrum, with a wavelength between 0.1 and 1mm; the scanners do not produce an image but a “fingerprint” — rather than blurry pictures of naked tourists, a TeraView scanner would return absorbance data that could be automatically analyzed to approve travelers or alert airport staff to investigate further

  • African nations do not have the means for meaningful improvements in airport security

    While some of the worst lapses, such as allowing spears or other potential weapons in carry-on luggage, seem no longer to occur, other aspects of airport security in Africa remain disquieting; One expert says that if airports in developing nations had to meet Western security standards, “they would ground all the airplanes, as simple as that”

  • Keeping underwear bombing in perspective

    The Nigerian underwear bomber and the Saudi suicide bomber who hid explosives in his body cavities (although it now appears that he, too, was an underwear bomber) point to a new, if so far ineffective, tactics on the part of al Queda; how serious is this threat? One expert says we should keep three things in mind: the threat is not serious because of inherent limitations involved in carrying incendiaries inside the human body or one’s underwear; one of two of these bombers may go through, though; the sheer complexity inherent in the effort involved in trying to prevent this type of bombing may erases any theoretical benefits and gains beyond a certain point; we may have reached that point

  • Implant Sciences targets $2 billion U.S. explosives detection market

    Implant Science estimates that the total U.S. market for explosives detection technologies may be greater than $2.0 billion by 2011; the company has launched a strategic initiative to sell its products to U.S. domestic law enforcement agencies and other security organizations that protect both public and privately owned critical infrastructure

  • Mirion delivers SPIR Detect to Italy

    California-based company delivers its radiation detection product to Italy’s Civil Defense Authority; the Italians say they will deploy the monitors to protect critical infrastructure facilities

  • Woman dodges prison time for killing dirty-bomb plotter husband

    A Maine woman is given suspended sentence for killing her white supremacist husband after he began to plan a dirty-bomb attack on President Obama; husband was also obsessed with child pornography, and the wife was afraid he would abuse their 9-year old daughter

  • Debate intensifies over full-body scanners

    The Christmas Day near-bombing invigorated an already-keen interest in whole-body scanners; there is debate going on over the effectiveness – and health risks – of the two main technologies available: millimeter-wave radiation and backscatter radiation; some suggest soft chemical ionization as an alternative
