• Dayton installs automated baggage screening system at airport

    On 17 May Dayton International Airport in Ohio will begin using a sophisticated new automated baggage screening system that will save time and resources; using a series of machines, the new system will automatically screen luggage for explosives; any suspicious bags will be flagged and sent to security screeners for more careful examination; TSA officials hope that the new machines will help reduce check-in times for passengers, increase efficiency, and even minimize the number of screeners needed

  • Car-based IED attacks an emerging threat in Mexico

    Intelligence analysts worry that Mexican drug cartels will increasingly turn to deadly car bombs in the escalating drug wars; drug cartels have already assassinated several government officials using improvised explosive devices (IEDs) planted in cars; in Mexico IEDs are easy to construct due to easy access to powerful commercial explosives that are widely used in the country’s mining and petroleum industry; due to strict gun laws, it is actually cheaper and easier to obtain explosives than guns; to defend against this emerging threat the U.S. consulate in Monterrey erected concrete barriers

  • Indian explosives detection technology comes to U.S.

    A south Carolina-based company signs a memorandum of understanding with India’s Defense Research and Development Organization (DRDO) to enhance the DRDO-developed Explosives Detection Kit (EDK) so it meets standards that will allowed it to be used by the U.S. military and homeland security

  • Insider threats in Afghanistan increase need for explosive detectors

    In Afghanistan suicide bombers are increasingly disguising themselves as friendly forces to successfully infiltrate secure allied bases and wreak havoc; April has been a deadly month for allied troops in Afghanistan with at least four attacks taking place where suicide bombers disguised themselves as police officers or members of the army; to protect against this threat, Thermal Matrix specializes in person-borne improvised explosive device (PBIED) detection devices; the firm has been working with the U.S military for the past several years to develop the Thermal Matrix ACT system which is capable of detecting suicide bombers from long distances; the system uses infrared imagery to analyze the heat signature of approaching individuals to determine if they are carrying any explosives

  • British company purchases American IED detection firm for $90M

    Last week the British defense firm Chemring finalized a deal to purchase Detection Systems, a subsidiary of General Dynamics, for $90 million; North Carolina based Detection Systems specializes in improvised explosive devices (IED) sensor systems; Detection Systems currently supplies the U.S. military with vehicle mounted IED detectors; the acquisition helps to enhance Chemring’s existing IED detection capabilities and provides growth opportunities for its chemical and biological detection programs; the purchase will not be finalized until the U.S. government reviews the proposal

  • Space technology of practical uses on Earth

    Terahertz technology developed for space missions to study the most distant objects in the universe is now finding a host of practical applications back on Earth; most clothing and packaging materials are transparent to Terahertz radiation, whereas skin, water, metal and a host of other interesting materials are not; this gives rise to some important day-to-day applications: detecting weapons concealed under clothing or inside parcels; distinguishing skin and breast cancer tissue; quality control of manufactures items and processes in factories

  • Trees as contamination detectors

    Determining the presence and concentration of contaminants has been an invasive, laborious process; now a Missouri University of Science and Technology team has developed a faster, more economical method of determining such contamination at miniscule levels; the Army has funded additional research for explosive residue detection

  • Army seeks long distance explosive detection scanners for people

    The U.S. Army is seeking to rapidly deploy long distance chemical detection devices that are capable of detecting explosives hidden on people; ideally, the devices will be able to sense the presence of explosives and chemicals on people standing, walking, or running from as far away as 100 yards; the Army wants to be able to field these capabilities within a year, so it is only considering mature technologies that are ready to be implemented; the request for proposals will close on 6 May

  • Russia to employ hi-tech bomb-sniffing dog

    In response to a series of terrorist attacks, Russia’s president Dmitry Medvedev has called on Russian military and security services to train more dogs as bomb sniffers; the dogs are trained not only in identifying explosives, but are also trained in carrying walkie-talkies so they can be given instructions from a distance, and to carry portable video cameras for in-building surveillance

  • Spate of dry-ice bombs explosions in Long Beach, Calif.

    A Long Beach officer is injured after an investigation of a dry-ice bomb left in an alley; a dry ice bomb is a homemade device that uses water, a bottle and dry ice, or frozen carbon dioxide; it can take anywhere from thirty seconds to an hour for a dry-ice bomb to rupture, depending on temperatures outside of the bottle

  • Battery-less chemical detector developed

    Conventional chemical detectors require an external power source, but Lawrence Livermore researchers have developed a nanosensor that relies on semiconductor nanowires rather than traditional batteries; the device overcomes the power requirement of traditional sensors and is simple, highly sensitive, and can detect various molecules quickly; its development could be the first step in making an easily deployable chemical sensor for the battlefield

  • New device uses sniffer bees to detect explosives

    The unassuming honeybees have a hidden talent — an even keener sense of smell than anyone first expected — which could make them one of the U.K.’s most ruthless and worst-feared weapons against terrorism; researchers developed a portable handheld sensor that holds thirty-six trained bees gently restrained in six cassettes inside the device; each is taught to recognize a particular odor and associate that smell with a food reward; the researchers have already trained their honeybees to detect a wide variety of explosive compounds and mixtures, including Semtex, C4, PE4, TNT, DMNB, gunpowder, and hydrogen peroxide

  • Ultra-sensitive sensor technology detects explosives, cancer

    Princeton researchers have invented an extremely sensitive sensor that opens up new ways to detect a wide range of substances, from tell-tale signs of cancer to hidden explosives; the sensor, which is the most sensitive of its kind to date, relies on a completely new architecture and fabrication technique developed by the Princeton researchers; the device boosts faint signals generated by the scattering of laser light from a material placed on it, allowing the identification of various substances based on the color of light they reflect; the sample could be as small as a single molecule

  • Spray-on explosives detector

    A chemist at Oklahoma State University has developed a spray-on material that detects explosives made from peroxides and renders them harmless; the material is a type of ink that contains nanoparticles of a compound of molybdenum. The ink changes color, from dark blue to pale yellow or clear, in the presence of explosives

  • Universal detector made of DNA building blocks

    Aptamers are composed of the building blocks of the genetic material DNA; scientists show that aptamers can be used quantitatively to detect and accurately examine multifaceted substances; a method for detecting such diverse substances as antibiotics, narcotics, and explosives - in effect, a universal detector — has been developed by researchers at the Max Planck Institute for Polymer Research in Mainz
