• Syrian rebels trained in handling, securing chemical weapons

    The United States and some of its European have issues contracts to defense contractors to train Syrian rebels on how to identify, handle, and secure chemical weapons stockpiles in Syria; some of the training is done in Jordan, but some of the contractors are already inside Syria, where they, and U.S. intelligence operatives, are working closely with friendly rebel groups to monitor Syria’s chemical weapons production and storage sites

  • Detection aircraft surveys 600 miles of PG&E California pipeline for gas leaks

    PG&E’s transmission pipeline is routinely surveyed each year, typically by ground crews; accessing rural areas with difficult terrain, however, can be time consuming, expensive, and unsafe for crews on the ground; aerial surveys often look for dead vegetation as an indicator of gas leaks

  • Improved technology to detect hazardous chemicals

    Scientists have developed a system quickly to detect trace amounts of illegal drugs, explosives, pollutants in rivers, or nerve gases released into the air; the new system can pick out a single target molecule from 10,000 trillion water molecules within milliseconds, by trapping it on a self-assembling single layer of gold nanoparticles

  • Nanotech detection device emulates dog's nose to detect explosives

    Inspired by the biology of canine scent receptors, scientists develop a chip capable of quickly identifying trace amounts of vapor molecules; the chip is part of a device which is both highly sensitive to trace amounts of certain vapor molecules, and able to tell a specific substance apart from similar molecules

  • New methods might drastically reduce the costs of investigating polluted sites

    In Europe there are over 20,000 complex and large contaminated areas. These so-called megasites threaten scarce land and water resources, create environmental and health risks, and result in economic and social costs; new methods may allow polluted sites to be investigated and monitored long term at significantly reduced costs

  • Keystone XL pipeline: reliability of remote oil-spill sensors questioned

    The oil industry plans to build thousands of miles of pipelines in the next five years, making leak detection a growing issue; many of the new pipelines will cross aquifers and rivers which are used for drinking water and irrigation; the Keystone XL pipeline has already experienced its share of controversies, and now there is a debate over the quality and reliability of the pipeline’s sensor system for remote detection of oil spills

  • Removing toxins from the environment

    A Florida State University chemist’s work could lead to big improvements in our ability to detect and eliminate specific toxic substances in our environment; the novel approach is based on stripping electrons from the toxic chemical known as fluoride; in addition to toxin removal, the approach has many other applications

  • Electronic nose detects airborne toxins down to the parts per billion level

    Research create an electronic nose device with applications in agriculture, industry, homeland security, and the military; the device can detect small quantities of harmful airborne substances

  • U.K. to help IRAQ destroy legacy chemical weapons

    U.K. scientists will provide training which will support the Iraqi government’s efforts to dispose of remnants of the chemical weapons amassed during Saddam Hussein’s regime

  • Resolving mystery odor alarms

    In the post-9/11, security-conscious era, unidentified odor often cause the precautionary evacuation of buildings, airport terminals, and more; a New Jersey company offers an educational video on the problem of mystery odors – and offers odor identification services to help identify and resolve mystery odor complaints

  • New rapid diagnostic test for pathogens, contaminants developed

    Using nanoscale materials, researchers have developed a single-step method rapidly and accurately to detect viruses, bacteria, and chemical contaminants; the method could be used to detect pathogens and contaminants in biological mixtures such as food, blood, saliva, and urine

  • Bomb threat? There’s an app for that

    In the first chaotic moments after suspicion of a bomb threat, first responders have a myriad of questions, assessments, and decisions to make, all at once, and all the while the scene could be changing rapidly: Is the bomb real? How large is the potential blast radius? Where will we evacuate people? Are there any critical infrastructure or special-needs population centers in the vicinity? Any schools, hospitals nearby? What roads should be closed? Which roads should stay open for evacuees? There are many more questions, many more uncertainties; DHS Science and Technology Directorate (S&T) and its private sector partners have now developed a must-have app: the First Responder Support Tools (FiRST) for computers and smartphones

  • New method uses gunshot residue to determine caliber, type of weapon used in crime

    Researchers have developed a method to determine the caliber and type of weapon used in a crime by analyzing gunshot residue (GSR); using near-infrared (NIR) Raman microspectroscopy and advanced statistics, the new technique may play a pivotal role in law enforcement cases and forensic investigations

  • Saab shows new CBRN detection system

    Saab introduces a new concept in CBRN detection: a CBRN detection and warning system designed for use by non-specialists in the field

  • New DNA-based chemical sensor acts as an all-electronic nose

    Chemical sensors are very good at detecting a single substance or a class of chemicals, even at highly rarified concentrations; biological noses, however, are vastly more versatile and capable of discriminating subtle cues that would confound their engineered counterparts; even highly trained noses, however, do leave a certain ambiguity when relaying a signal
