• Sandia Labs developed an IED-disabling water-blade device

    A device developed by Sandia National Laboratories researchers that shoots a blade of water capable of penetrating steel is headed to U.S. troops in Afghanistan to help them disable deadly IEDs; the portable clear plastic device is filled with water and an explosive material is placed in it that, when detonated, creates a shock wave that travels through the water and accelerates it inward into a concave opening; when the water collides, it produces a thin blade

  • Drive-by full-body scanning

    Massachusetts-based American Science & Engineering is selling van-mounted backscatter X-ray detection system to law enforcement; these vans can be driven past neighboring vehicles to see their contents

  • Skeletal scans could be newest screening technique

    The adult skeleton has 206 bones; size, shape, density, and joint structure make each skeleton slightly different; throw in an extra lumbar vertebrae or extra rib — which some people have — as well as previously broken bones, implants, screws, and other identifying characteristics, and the signatures become even more individual

  • Flir to acquire sensor maker ICx for $274 million

    Flir, maker of thermal imaging technology, is acquiring ICx for $274 million; the merger will give Flir the capability to expand into the market for advanced sensors for chemical, biological, radiological, and nuclear explosives (CBRN) detection for homeland security and defense

  • Detecting fertilizer-based IEDs

    Since 2008, IEDs have accounted for more than half of all fatalities incurred by NATO forces in Afghanistan; last year, 275 NATO soldiers died in IED attacks, and that number will likely be surpassed this year; already 228 NATO soldiers have died due to homemade bombs this year; the U.S. military continues to search for IED countermeasures

  • 3D, interactive X-ray to offer dramatic improvement in security scans

    The latest X-ray scanners can glean information about the atomic or molecular weight of a substance, and so help distinguish between materials, but the results are crude; the best they can manage is to show metal objects in one color, organic materials in another, and everything else in a third color; a new technique — called kinetic depth effect X-ray imaging, or KDEX — builds up a 3D image of the object which can be rotated and viewed from a wide range of angles

  • New baggage screening system from Morpho Detection evaluated

    Unlike most baggage-screening systems that create two-dimensional images of objects inside luggage, the CTX 9800 DSi scanners from Morpho Detection create three-dimensional images that can be digitally manipulated by personnel when a bag is deemed to be suspicious; the machines also use advanced software to detect suspicious items; Mineta San Jose International Airport once used 28 machines to process 1,800 bags an hour, but the new system will be able to process the same number of bags using eight machines and require fewer employees to supervise the process; the technology reduces reliance on human observation and interaction with the bags; for the majority of bags, employee contact is only required when a piece of luggage is placed on or taken off the conveyor belt

  • 100 percent air-cargo screening is going smoothly -- so far

    On 1 August a law mandating 100 percent screening of cargo transported on passenger aircraft took effect; the shipping industry says that, so far, are off to a good start; experts point out that August is relatively slow shipping month, and that the real test will come in mid-September, when the busy air cargo shipping season begins

  • Airport screening specialist Reveal Imaging acquired by SAIC

    SAIC acquires Reveal Imaging Technologies of Bedford, Massachusetts; Reveal was founded in 2002 in response to the U.S. government’s mandate for aviation security screening after the attacks of 9/11. The company has developed imaging technologies for screening airport baggage and detecting explosives in checked luggage

  • New explosives detection technologies show promise

    An adversary who is willing to die trying to carry out a mission is one of the reasons why more conventional security organizations find it so difficult to pursue their protection mission effectively in an asymmetrical war — the kind of war terrorists engage in; new explosive detection technologies may be of help

  • Better to teach old dogs new tricks

    DHS recently announced that it wants to buy 3,000 dogs from breeders — at a cost of $4,535 per dog — to increase its force of canines who sniff out explosives, cash, and drugs; since only 20 percent of dogs who are selected for service programs successfully complete the training process, this plan will actually result in breeding 15,000 dogs, of which 12,000 will end up in shelters; one expert offers an alternative: DHS should follow the lead of the Hearing Ear Dog Program and many police departments and fill its ranks with dogs adopted from shelters

  • Detecting sticky bombs

    Sticky bombs — explosives affixed to a car, which explode when you turn the ignition key — as the stuff of movies dealing with the Mafia, but terrorists used them as well (as do the secret services of some countries); researchers at Argonne National Laboratory offer a way to detect surreptitiously placed sticky bombs

  • New radiation mechanism may ward off oil spills, terrorism

    New radiation mechanism in the terahertz range could be used to destroy cancer cells, track miniscule traces of explosives hidden under clothing, and trace and potentially destroy specific chemicals that damage the environment and our bodies

  • TSA wants more bomb-sniffing dogs to protect air, ground travelers

    The Transportation Security Administration (TSA) wants to increase the role dogs play in sniffing out terror threats at U.S. airports and other mass transit systems; TSA requested $71 million from Congress to train and deploy 275 explosives detection canine teams — bomb dogs and their handlers — at transportation facilities

  • TSA will miss 1 August air cargo screening deadline

    TSA will miss the congressionally mandated 1 August deadline of having 100 percent of cargo carried on planes screened; all cargo loaded onto passenger planes departing from domestic airports will be checked for explosives by the deadline, but screening all international cargo entering the United States has proved more challenging; the reason: an estimated 2.8 billion pounds of air cargo arrives in the United States every year on passenger aircraft from 94 different countries; the cargo is handled in the global air cargo supply chain by a vast number of participants; each of these 94 countries has unique air cargo security programs and regulatory requirements, many of which differ significantly from those required by TSA
