• Decision Sciences, Battelle to develop passive nuclear material detector

    The companies will rely on work done by Decision Sciences and Los Alamos National Laboratory on muon tomography and gamma ray detection applications; the collaborative effort will yield a multi-mode system capable of detecting nuclear materials across the complete threat spectrum, including shielded and unshielded nuclear materials

  • Thermal-boosted infrared detection scanners address radiation, privacy concerns

    Iscon Video Imaging’s proprietary thermal-boosted infrared detection technology shows objects and clothing without any harmful radiation; the detection system creates a temperature differential between clothes and a hidden object

  • Thermo Fisher Scientific to acquire Ahura Scientific for $145 million in cash

    Ahura Scientific’s products expand Thermo Fisher’s portfolio of portable analytical devices designed to provide customers with the ability rapidly to identify and authenticate a range of molecular and elemental substances in the field; Ahura Scientific has approximately 120 employees and generated full-year revenue of approximately $45 million in 2009; Thermo Fisher Scientific had $10.5 billion in revenues in 2008; the company has approximately 35,000 employees and serves more than 350,000 customers

  • Terahertz scanners may detect what whole-body scanners miss

    A typical full-body scanner works by bouncing X-rays off an individual’s skin to produce an outline image of the person’s body; these images must then be studied by an operator who makes the call whether there is a potential explosive present or not; the operator’s subjective view makes the system more fallible; terahertz technology works by sweeping a terahertz beam across a person and then using sensors to detect the radiation that reflects back; explosives and benign substances such as candy have a different terahertz spectrum, or fingerprint, that can be classified by TeraView software

  • Battling against biological threats with ultrasonics

    A tweezers-like device uses ultrasonics to detect bioterror agents; when a small sample such as a powdery anthrax mix is placed inside the device, an array of piezoelectric transducers would generate an ultrasonic force field onto the sample; security officials would be able to detect anthrax from innocuous powders in the mix through differences in compressibility and density

  • Research aims to improve airport security

    From body-part censors to cameras that recognize faces, Carnegie Mellon’s CyLab is working with security technology that assuages privacy concerns; CMU’s Instinctive Computing Lab, eventually envisions a system that can wipe out the body image entirely, picking up only weapons, which will appear to be floating in space

  • U.S. Supreme Court will eventually rule on the legality of whole-body scanning

    In the absence, at least for now, of an overarching U.S. Supreme Court decision, how would U.S. courts react to the privacy concerns surrounding whole-body searches, assuming a legal challenge is initiated against taking pictures of one’s private parts while trying to fly to the United States? An answer may be found on the fact that at least two U.S. circuit courts of appeal have beaten back challenges to airport security measures; in the most recent one, in 2006, the 3rd U.S. Circuit Court of Appeals — Justice Samuel Alito’s old stomping grounds — ruled a suspicionless, unwarranted search during airport screening was allowable under the “administrative search doctrine”; the doctrine, elucidated in a 1971 ruling by the 9th U.S. Circuit Court of Appeals, said that “searches conducted as part of a general regulatory scheme in furtherance of an administrative purpose, rather than as part of a criminal investigation to secure evidence of a crime, may be permissible under the Fourth Amendment though not supported by a showing of probable cause directed to a particular place or person to be searched”

  • 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
