• More rigorous approach to training of explosive-detecting dogs

    With a sense of smell much greater than humans, dogs are considered the gold standard for explosive detection in many situations. But that does not mean there is no room for improvement. In a new study, scientists report on a new, more rigorous approach to training dogs and their handlers based on real-time analysis of what canines actually smell when they are exposed to explosive materials.

  • U.S. imposes enhanced security measures on U.S.-bound flights from 105 countries

    The United States will impose tough new security measures on all international flights bound for the United States. DHS officials said 280 airports in 105 countries would be affected by the tightened security, affecting around 2,000 flights a day. Airlines have been warned that a failure to comply with these enhanced security measures would carry consequences, including banning laptops altogether on the airlines’ U.S.-bound flights.

  • Navy tests new mine-detection drone

    The new Mine Warfare Rapid Assessment Capability (MIW RAC) system is a portable, remote-controlled system that can detect buried or underwater mines during amphibious beach landings. It’s designed to help explosive ordnance disposal teams quickly find mines and dangerous metal obstacles within coastal surf zones and very-shallow-water zones. MIW RAC consists of a one-pound quadcopter outfitted with an ultra-sensitive magnetometer sensor system to detect mines and provide real-time search data to a handheld Android device.

     

  • Helping explosive detection canine teams across the U.S.

    Dogs are uniquely suited to sniffing out explosives – their sense of smell is more than a million times stronger than a human’s. Harnessing this natural ability to help law enforcement identify explosives requires specialized training and testing. Many detection canine teams, however, have limited access to critical training materials and limited time to establish rigorous training scenarios. DHS S&T’s Detection Canine Program has developed an initiative to support these needs for the nation’s more than 4,000 explosives detection canine teams.

  • Bomb squads to compete in annual Robot Rodeo

    Robots are life-saving tools for bomb squads and emergency response teams, providing them a buffer from danger. Sandia National Laboratories is hosting the 11th annual Western National Robot Rodeo, a four-day event where civilian and military bomb squad teams get practice using robots to defuse diverse, dangerous situations.

  • Glowing bacteria detect buried landmines, unexploded ordnance

    About half a million people around the world are suffering from mine-inflicted injuries, and each year an additional 15 to 20 thousand more people are injured or killed by these devices. More than 100 million such devices are still buried in over seventy countries. The major technical challenge in clearing minefields is detecting the mines. Researchers have developed a potential answer to this urgent need: a novel, functional system combining lasers and bacteria to remotely map the location of buried landmines and unexploded ordnance.

  • DHS S&T opens new explosives detection lab

    DHS S&T officially opened a new Test & Evaluation Laboratory building at the Transportation Security Laboratory (TSL) on Wednesday. Located at the William J. Hughes FAA Technical Center in Egg Harbor Township, New Jersey, the new building expands TSL’s reinforced laboratory space for conducting tests of explosives detection systems. TSL is the only laboratory authorized to provide certification and qualification testing of explosives detection systems for the TSA.

  • Improve trace detection of explosives by sniffing like a dog

    By mimicking how dogs get their whiffs, a team of government and university researchers have demonstrated that “active sniffing” can improve by more than ten times the performance of current technologies that rely on continuous suction to detect trace amounts of explosives and other contraband.

  • Nanobionic spinach plants can detect explosives

    Spinach is no longer just a superfood: By embedding leaves with carbon nanotubes, MIT engineers have transformed spinach plants into sensors that can detect explosives and wirelessly relay that information to a handheld device similar to a smartphone. This is one of the first demonstrations of engineering electronic systems into plants, an approach that the researchers call “plant nanobionics.”

  • Countering enemy IEDs in culverts

    Culverts are creeks or streams that run under roads to prevent flooding, and that terrorists often use these areas to kill soldiers. The Joint Improvised-threat Defeat Agency (JIDA) challenge, held 13-21 September at Fort Benning, tested industry vendor equipment from around the United States in order to counter enemy improvised explosive devices (IEDs) in culverts.

  • X-ray vision: Bomb technicians strengthen their hand with Sandia’s XTK software

    X-Ray Toolkit (XTK), an image-processing and analysis software developed at Sandia National Laboratories, has been adopted by the military and emergency response communities in the United States and around he world. “XTK is the standard in the field not only nationally, but internationally. It made the average bomb tech a better bomb tech,” said Craig Greene, a special agent and bomb technician at the Albuquerque, New Mexico FBI. “In the past twenty years, the bomb technician community has progressed from the Stone Age to the twenty-first century in terms of equipment and procedures, and XTK is a major part of that progression.”

  • Super-sniffer mice detect land mines, decode human olfactory system

    Researchers have created super-sniffer mice that have an increased ability to detect a specific odor. The mice, which can be tuned to have different levels of sensitivity to any smell by using mouse or human odor receptors, could be used as land-mine detectors or as the basis for novel disease sensors.

  • Can next-generation bomb ‘sniffing’ technology outdo dogs on explosives detection?

    With each terrorist attack on another airport, train station, or other public space, the urgency to find new ways to detect bombs before they’re detonated ratchets up. What researchers have wanted to develop for a long time is a new chemical detection technology that could “sniff” for explosives vapor, much like a canine does. Many efforts over the years fell short as not being sensitive enough. My research team has been working on this problem for nearly two decades – and we’re making good headway. Inspired by the tremendous detection capabilities of dogs, we’ve made remarkable advances toward developing technology that can follow in their footsteps. Deploying vapor analysis for explosives can both enhance security levels and provide a less intrusive screening environment. Continuing research aims to hone the technology and lower its costs so it can be deployed at an airport near you.

  • Iraq to stop using fake bomb detectors in wake of Baghdad attack

    In the wake of the deadliest terrorist attack in Iraq since 2003, Iraq’s prime minister Haider al-Abadi has instructed all the country’s security forces – the federal and local police and the army — to stop using fake bomb detectors at the hundreds of security checkpoints across the country. A British businessman, James McCormick, purchased thousands of the novelty golf ball finders for $19.95 each, repackaged them, and then sold them to Iraq and other nations as advanced hand-held bomb detectors. McCormick charged $40,000 for each of the repackaged golf-ball finders.

  • Speedy terahertz-based system could detect explosives

    Terahertz spectroscopy, which uses the band of electromagnetic radiation between microwaves and infrared light, is a promising security technology because it can extract the spectroscopic “fingerprints” of a wide range of materials, including chemicals used in explosives. Spectroscopic system with chip-scale lasers cuts detection time from minutes to microseconds.
