• Los Alamos lab's toxic waste seeps toward New Mexico's water sources

    Radioactive debris has been found in canyons that drain into the Rio Grande, but officials at the Los Alamos National Laboratory say there is no health risk; to comply with New Mexico’s clean up orders, the lab has installed about 300 monitoring wells and gauges, contaminated soil is being removed from canyon bottoms, wetlands are being planted, and small dams built to arrest the flow of polluted storm water

  • GAO: TSA continues to face challenges in finding and deploying checkpoint screening technology

    Since TSA’s creation, ten passenger screening technologies have been in various phases of research, development, test and evaluation, procurement, and deployment, but TSA has not deployed any of these technologies to airports nationwide

  • U.S. considers facial recognition, eye scans at border

    DHS proposes to spend billions of dollars collecting fingerprints and eye scans from all foreign travelers at U.S. airports as they leave the country; already, the United States demands biometric data, typically fingerprints and digital photos, from arriving air and sea travelers with visas; the aim is to try to ensure the person matches the individual who was given the visa overseas. Canadians and Mexicans are currently exempt

  • Day of Americans serving as mobile chemicals sensors nears

    NASA Ames scientists demonstrate cell phone chemical sensor; the prototype device, designed to be plugged in to an iPhone, collects sensor data and sends it to another phone or a computer via telephone communication network or Wi-Fi

  • Iraqis use "magic wand" at checkpoints to detect explosives; U.S. officer: this is "laughable"

    The Iraqi government has spent tens of millions of U.S. aid dollars to buy thousands of “magic wands” which are supposed to detect explosives at checkpoints; one American officer says the device works “on the same principle as a Ouija board”; another officer says that to believe the claims of the British company which is selling the device, and of the Iraqi authorities that swear by it, “would be laughable” — except that people are dying as a result; “[the company and Iraqi government have] crossed an insupportable line into moral depravity” he says

  • Gait-recognition biometric technology to help soldiers manning checkpoints

    SET Corporation is developing a technology which directs low-power radar beams at people — who can be 50 yards or more away; early research indicates that this method could one day be augmented with video-analysis software that spots bombers by discerning subtle differences in gait that occur when people carry heavy objects

  • CBP orders advanced cargo and customs screening from OSI

    OSI’s Security division, Rapiscan Systems, has received approximately $29 million in orders from the U.S. Customs and Border Protection (CBP) to provide multiple units of its cargo and vehicle inspection solutions

  • Robot fish could monitor water quality

    Michigan State University researchers develop robots that use advanced materials to swim like fish to probe underwater environments; robotic fish — perhaps schools of them operating autonomously for months — could give researchers far more precise data on aquatic conditions, and the quality — and security — of the water supply

  • New airport security scanners raise concerns

    Canada’s privacy watchdog said it agreed with federal authorities that full-body scans should be used at Canada’s airports; security personnel would be in a separate room while viewing the image and would never come in contact with the person being screened

  • New high-precision chemical detector to be commercialized

    A start-up launched by the University of Delaware is preparing to commercialize a high-precision detector — a planar-array infrared spectrograph — that can identify biological and chemical agents in solids, liquids, and gases present at low levels in less than a second

  • Washington State will put seismic sensors on viaduct

    Alaskan Way Viaduct in Washington State is crumbling, but it still carries more than 100,000 cars per day, and remains the city’s second-busiest north-south arterial after Interstate 5; until a $4.2 billion replacement project opens in 2015, the state will place sensors that on the viaduct which will close the elevated roadway at the first sign of seismic activity

  • New tool detects -- and neutralizes -- pathogens in mail

    Using the mail as a tool for bioterror attacks may or may not kill many people, but it will paralyze a company or an organization; the psychological damage is incalculable; new tool offers mail-room protection

  • New device to "smell" human fear

    City University London’s researchers launch a project aims to develop two sensor systems that can detect the unique chemical signature of the fear pheromone, assessing the stress of an individual and interpreting it in security-critical contexts

  • New method takes 0.2 second to test for explosive liquids

    German scientists develop a novel nanoelectronic device which uses electromagnetic radiation to identify explosive liquids, or liquid components for the fabrication of explosives, in usual plastic bottles almost instantly

  • DARPA seeking to improve bio-threat detectors

    The agency is requesting proposals for a device that would enable faster, more accurate detection of a broad range of biological agents; DARPA hopes to create a biosensor that would identify viral and bacterial threats, and do so using a natural first-line of defense: human antibodies
