• Chemical sensor may stop terrorists

    Terrorists may find it harder to carry out attacks thanks to a new explosives detector developed by Turkish scientists; the scientists have designed a colorimetric sensor that can selectively detect the peroxide-based explosives TATP and hexamethylenetetramine (HMTD) and can be used on-site

  • Green decontaminants to breaking down chemical weapons

    New products developed non-toxically to decontaminate nerve gas, mustard gas, radioactive isotopes, and anthrax. The formulas are based on ingredients found in foods, cosmetics, and other consumer products

  • Tiny sensors embedded in cell phones identify, map airborne toxins in real time

    Cell phones are everywhere people are, so University of California-San Diego’s researchers want to turn the devices into chemical sensors; the tiny sensor, a porous flake of silicon, changes color when it interacts with specific chemicals. By manipulating the shape of the pores, the researchers can tune individual spots on the silicon flake to respond to specific chemical traits

  • Non-toxic cleaners for terrorist attacks

    Traditional chlorine- and lye-based cleaning agents are potentially hazardous and can react with chemical weapons and other materials in the environment to form new toxic substances; military researchers non-toxic, ultra-strength cleaners that could be used in the aftermath of a terrorist attack; the peroxide-based “green” decontaminants are tough enough to get rid of nerve gas, mustard gas, radioactive isotopes, and anthrax

  • New sensor speeds water analysis

    New sensor creates a single procedure for in-situ monitoring of chlorinated hydrocarbons in water, obviating the need for laboratory-based technologies for the analysis of water contaminants, which are time consuming, labor intensive and expensive

  • Taliban uses poisonous gas in attack on Kabul girls school

    The Taliban continues its violent campaign against girls’ education in Afghanistan; the Taliban’s latest tactics; poisonous gas attacks on girls’ schools, aiming to scare students and teachers; in mid-April the Taliban attacked three girls’ schools in northern Afghanistan; yesterday, the Taliban attacked a school in the middle of Kabul; twenty-two students and three teachers were hospitalized

  • Planned security network for Lower Manhattan would not have identified bomber

    New York City plans to install a protection system in Lower Manhattan which will consist of surveillance cameras, license plate readers, and chemical sensors; the system will be able to record and track every vehicle moving between 34th and 59th Streets, river to river; because neither the S.U.V. used in the attempt last Saturday nor the license plate on it had been reported stolen, it would not have raised any immediate red flags

  • Taliban suspected in poisonous gas attacks on female Afghan students

    The Taliban is suspected in three separate poisonous gas attacks on girls schools in northern Afghanistan; eighty-eight girls were admitted to hospitals with what doctors describe as symptoms associated with “unknown gasses”; the Taliban banned education for women during its rule from 1996 to 2001, and girls education is still a controversial issue in Afghanistan today

  • Laser decontamination for post-chemical attacks, accident clean-up

    Many building materials — like cement and brick — are extremely porous; getting contaminants off surfaces like these is difficult, since they can inhabit cracks and pores; cleaning up chemical-contaminated structures can be difficult, costly, and time-consuming; what if terrorists attacked an urban center with chemicals? Researchers say the answer is to use laser to decontaminate an area after a terrorist attack or an industrial accident

  • DHS moving forward on cell-all smartphone chemical detection technology

    DHS wants to turn smartphones into chemical sensors; owners of smartphones would volunteer to have tiny chemical sensors embedded in their devices; millions of American could thus become roving chemical sensing nodes to alert authorities of terrorist — or accidental — chemical toxin release

  • Smaller, more sensitive sensors revolutionize public safety, medicine

    There is a revolution under way — the growth of single-molecule detection; sensors known as “e-noses” function as artificial snouts that can identify the most minute trace of compounds in the air, while microfluidic “lab on a chip” sensors can flag individual DNA strands and other entities in liquids; important implications for public safety and medicine

  • Smiths Detection, 20/20BioResponse in global distribution agreement

    The agreement is for BioCheck powder screening test kits; the biological threat assessment tool will strengthen Smiths Detection’s portfolio of emergency and first response solutions

  • Home-made poisons pose risks for first responders

    A 23-year old St. Petersburg, Florida resident committed suicide by filling his car with gas which was a custom-made combination of pesticides and cleaning products; he learned about the deadly concoction from the Internet

  • NYC subway security system: past due, over budget

    In 2005 the Metropolitan Transportation Authority (MTA) awarded Lockheed Martin a $212 million contract to create a cutting-edge security system the city’s subways, buses, and commuter trains; the cost of the security system has ballooned to $461 million and is now over-schedule by a year-and-a-half; The MTA. has $59 million left in capital funding

  • Researchers propose a new way to scan cargo containers

    In 2007 the U.S. government set itself the goal of screening all aviation cargo loaded onto passenger planes and all maritime cargo entering the country for both explosives and nuclear materials; this is an ambitious goal: there are more than ten millions containers entering the United States every year through sea ports and land border crossings, and there are more than 28,000 commercial flights
