• New airport scanner can detect liquid explosives

    Passengers boarding airplanes could soon be walking through security checkpoints carrying liquids once more thanks to a high tech scanner capable of detecting liquid explosives; the device, developed by U.K. based Kromek, is capable of identifying dangerous liquids within seconds and does not require the container to be opened

  • Documents reveal TSA ignored dangers of body scanners

    The Electronic Privacy Information Center (EPIC) says that is has official documents that reveal the Transportation Security Administration (TSA) deliberately ignored warnings that airport body scanners pose a health risk; the internal documents and email exchanges show that TSA officials brushed aside concerns that employees raised after noticing that a large number of workers had cancer, strokes, and heart disease after working near the body scanners

  • Navy funds development of new explosives detection technology

    The Navy recently awarded researchers at Texas Tech University a four year $1.2 million grant to develop a more effective method to detect explosive materials; the project is spearheaded by four Texas Tech professors specializing in chemical engineering; one professor explained, “In layman’s terms, basically we’re trying to enhance detection for explosives”

  • Mud triggers Logan alarm

    Scanning machines at Logan Airport detected minute traces of nitrates in a checked luggage, and sounded the alarm; two gates were evacuated as a precaution; police found that the nitrates emanated from mud sample a Honk Kong University doctoral student was carrying in the luggage; the samples were to be used in research

  • Airport Checkpoint of the Future unveiled

    Attendees of the 67th annual Air Transport Association (IATA) annual meeting and World Air Transport Summit in Singapore got a first look at a prototype version of the airport security Checkpoint of the Future; the prototype checkpoint is specifically designed to allow passengers to pass through without having to remove their shoes or get patted down; to make travelling more pleasant and less invasive, the new security checkpoint is outfitted with a suite of sophisticated sensors including eye scanners, x-rays, and metal and liquid detectors

  • New detection system uses ultraviolet light to spot explosives

    More than 625 million travelers will take to the air before 2011 is over; the passengers’ carry-on luggage and checked baggage are screened for explosives — but University of Florida researchers say there is a better way to do so; the UF scientists say they have developed the first explosive detection system in the world that utilizes ultraviolet light to zero in on specks of dangerous explosives found in and on luggage; the explosives detection market is estimated to exceed $3 billion in the U.S. alone

  • Bomb sniffing dogs deployed to Long Island ferry

    A New York ferry company has become the first in the United States to receive federal grants to pay for the deployment of explosive detection canine teams; the Bridgeport & Port Jefferson Steamboat Company is teaming up with Long Island K-9 service to use bomb sniffing dogs to detect any explosives aboard the ferries; the canine teams will inspect every car that enters the ferry; teams were initially deployed on 13 May and the contract will last for three years

  • Scientists continue to raise doubts about safety of full body scanners

    The controversy over the Transportation Security Administration’s (TSA) body scanners lingers on as scientists continue to question the safety of these devices that expose millions of people to trace amounts of radiation; TSA officials maintain that their full body x-ray scanners are safe as they only expose individuals to negligible amounts of radiation, the equivalent of two minutes of flying; despite these assurances, a group of five scientists recently sent an open letter to the White House Science advisor; the scientists argue that the tests used to validate TSA’s claims contain critical flaws, lack transparency, and have not been independently verified

  • Texas House prohibits intrusive airport pat downs

    The Texas House of Representatives approved a bill that would make invasive pat downs at airports a crime; pat down procedures that would be covered under the measure are inspections that touch the anus, sexual organ, buttocks, or breast of another person including through the clothing, or touches the other person in a manner that would be offensive to a reasonable person; the law would not be enforceable since state legislatures have no authority over federal agencies such as the TSA

  • Infrared sensors could help police detect suicide vests

    Sophisticated infrared sensors originally designed for the U.S. military could soon be used by local police departments to detect suicide bombers; Thermal Matrix USA initially designed its Access Counter IED Technology system to assist military personnel in Iraq and Afghanistan identify potential suicide bombers, but hopes to create a model that local law enforcement agencies can deploy; the company has modified its product to significantly reduce its size, weight, and deployment time to be more practical; the devices are capable of detecting any hidden objects including knives, guns, plastics, and even liquids

  • Remote bomb detection sensors

    European scientists are embarking on a project to develop a network of state-of-the-art sensors capable of detecting hidden explosives; the sensors will work by detecting the chemical traces of explosive vapors in the air in order to provide early warning to security services and protect vulnerable urban populations from the threat of Improvised Explosive Devices (IEDs), often used by terrorist organizations

  • Researchers use bee venom to detect explosives

    Using bee venom, researchers have developed new bomb detectors that are so sensitive they are capable of detecting a single molecule of an explosive; when chemical engineers at the Massachusetts Institute of Technology (MIT) coated carbon nanotubes in bombolitins, protein fragments found in bee venom, they discovered that these proteins reacted with nitro-aromatic compounds like TNT at the molecular level; current bomb detectors rely on spectrometry which analyzes charged particles as they move through the air, which makes them far less sensitive than the recently developed bee-based detectors

  • New 2-in-1 explosive detector and neutralizer

    A two-in-one material that can both detect and neutralize explosives of the type favored by terrorists is unveiled; the material is made of metal oxide nanoparticles so small that 50,000 could fit across the width of a single human hair; it changes color in the presence of certain explosives, alerting emergency responders to the threat; it also can be sprayed onto bombs or suspicious packages to inactivate certain explosives

  • New sensor detects minute traces of explosives

    MIT chemical engineers develop a new sensor that can detect minute traces of explosives; the new sensors would be more sensitive than existing explosives detectors — those commonly used at airports, for example — which use spectrometry to analyze charged particles as they move through the air

  • ATF cracks down on bombs used to scare seals

    Much to the frustration of California fishermen, the U.S. Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) is starting to regulate the firecrackers used to scare away seals from fishing lines; beginning 1 May, ATF officials will begin enforcing a federal law that mandates anyone who purchases the seal “bombs” to obtain a special permit and clear a background check in order to prevent terrorists or criminals from using them; the bombs resemble M-80 firecrackers and are shot from a gun; fishermen and farmers use them to scare away animals like hungry birds or seals
