• How safe are U.S. subways?

    In a report last year, the GAO said: “Certain characteristics of mass transit systems, such as multiple access points and limited barriers to access, make them inherently vulnerable to terrorist attack and therefore difficult to secure; high ridership, expensive infrastructure, economic importance, and location in large metropolitan areas or tourist destinations also make them attractive targets for terrorists because of the potential for mass casualties and economic damage”

  • Senator Collins: U.S. airport full-body scanners inferior to those deployed in Amsterdam

    Maine’s junior U.S. senator says the full-body scanners DHS is deploying in the wake of the Christmas Day airline bomb threat are not the best devices available

  • Uranium-mining nations ignore UN-mandated measures on nuclear terror

    In the aftermath of the 9/11 terror attacks and the 2004 uncovering of the Pakistan-based A. Q. Khan nuclear smuggling network, the United States pushed Resolution 1540 through the UN, which required states to impose strict security measures on nuclear materials and report on the progress they have made in this regard; many states have not bothered to report — almost all them in Africa; especially worrisome is the situation in Niger, the Democratic Republic of the Congo, Zambia, Malawi, and the Central African Republic

  • Camgian awarded DARPA UAV-UGS fusion contract

    Today’s soldiers rely on advanced ground and airborne sensors to identify, track, and monitor critical targets; as stand-along platforms, UAVs and unattended ground sensors (UGS) have operational limitations such as endurance, coverage, and target resolution; Camgian is teaming up with BAE Systems to exploit the fusion of these assets in an automated network architecture to provide powerful ISR capability

  • Tularemia bacteria detected in Columbus, Ohio; no bioterror attack suspected

    BioWatch sensors in Columbus, Ohio, last week picked up higher than normal presence of the bacteria tularemia — a bacteria which may be used in bioterror attacks; Columbus Public Health officials continued to emphasize that people are not at risk and there is no suspicion that bioterrorism was attempted here

  • New technology enables machines to detect microscopic pathogens in water

    Detecting common pathogens in drinking water soon may no longer be bottle-necked under a laboratory microscope; Texas A&M researchers found a way to substitute humans with automatic image analysis systems

  • Students design innovative wastewater treatment process for removing pharmaceuticals

    More and more pharmaceuticals end up in countries’ water supply; four Canadian chemical engineering students have designed an advanced wastewater treatment system which would remove 90 percent of pharmaceuticals and endocrine-disrupting compounds (EDCs) using commercially available technology

  • Biochip technology reveals fingerprints of biochemical threats

    The biochip offers a chance to determine the signatures of biological agents that can be used for bioterrorism, most notably the bacterium that causes anthrax, Bacillus anthracis; while some scientists have used DNA analysis to identify particular strains of the anthrax bacterium, the biochips help scientists and government officials learn how anthrax bacteria are grown, narrowing the pool of potential suspects

  • Thermo Fisher Scientific granted two U.S. patents for radiation detection instruments

    Thermo Scientific RadEye PRD will help border guards, customs agents, or counterterrorism teams detect radiation sources more effectively than conventional personal detectors

  • Children must go through full body scanners at U.K. airports

    U.K. transport minister says that to exclude children from going through full body scanners risked undermining the security measures at U.K. airports; the government’s code of practice on the scanners said airport security staff had all been vetted, including a check of criminal and security service records

  • Nigeria installs body scanners at airport

    Lagos international airport installs three full-body scanners at a cost of $300,000 each. Nigeria’s three other international airports — in the capital Abuja, the oil town of Port Harcourt, and the largest northern city, Kano — are also scheduled to be equipped with the scanners

  • Day of trained sniffing bees is here

    The bee’s discreet sense of smell, equivalent to a dog’s, is being exploited as a much cheaper way to detect various odors in the environment; a U.K. company is now training bees to sniff out explosives and land mines — but also to identify diseases and cancers in people and animals, detect rapidly spreading bacteria in food, and identify dry rot in buildings

  • Airport sensor detects explosives hidden in the body

    Smiths Detection says that the 16HR-LD model of its B-Scan technology can see everything; the machine’s low-dose security technology is able to see all internal body cavities for the detection of concealed threatening objects, such as bombs and detonators

  • Better explosives detection for soldiers, first responders in the field

    From a chemical viewpoint, developing a detector for nitroaromatic compounds such as TNT is difficult because such compounds have a low vapor pressure, meaning their concentration in air at room temperature is around six parts per billion; MIT researchers develop cantilever sensors which use functional coatings to transduce detection of chemicals into a signal; the coating, usually a polymer, swells up when it reacts with the target analyte and deflects the cantilever

  • TSA: Full-body scanner safe for prostheses

    Full-body scanners are safe for passenger with artificial body parts — from replaced hips to augmented breasts; TSA says the scaners uses low-energy X-rays that do not penetrate the skin: prosthetic devices, artificial limbs, and surgically replaced body parts will not show up on the body scan image
