• New detection device for forensic and security applications

    A new biological sampling and detection device could soon be used by first responders in the forensic and security sectors; the patented technology allows for rapid sampling of up to eight targets simultaneously, testing powder, liquids, or surfaces directly and has applications across the forensic and security areas

  • Deadly E. coli strain decoded

    The secret to the deadly 2011 E. coli outbreak in Germany has been decoded; the deadliest E. coli outbreak ever, which caused fifty-four deaths and sickened more than 3,800 people, was traced to a particularly virulent strain that researchers had never seen in an outbreak before

  • 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

  • Northrop Grumman's biodetection solution completes field test

    Northrop Grumman says its Next Generation Automated Detection System (NG-ADS) for homeland defense applications has successfully completed a field test and is ready for the program’s next phase

  • 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

  • Detecting biological terror agents

    PositiveID Corporation is testing its M-BAND bioagent detection system in preparation for DHS’s $3 billion BioWatch procurement; M-BAND can be remotely set to detect for DNA-based pathogens alone, with or without either RNA-based organisms or toxins, or for all three types of pathogens simultaneously at remotely programmable intervals

  • New biosensor checks for toxicity in real time

    Researchers have married biology and engineering to develop a biosensor – called Dip Chip – that can warn of toxicity in real time; one of the chip’s advantages is its ability to identify toxicity as a biological quality instead of specific toxic chemicals; because the chip measures general toxicity, it will pick up on any and all toxic materials — even those that have not been discovered or invented yet

  • Using LED technology for UV disinfection

    UV light can be used to disinfect, treat drinking-water, sterilize surgical tools, and more; technologies that use aluminum nitride LEDs to create UV light, however, have been severely limited because the substrates which served as the foundation for these semiconductors absorbed wavelengths of UV light which are crucial to applications in sterilization and water treatment technologies; researchers have developed a solution to the problem

  • Bomb-sniffing dogs used in Everglades python invasion

    Burmese pythons have invaded the Florida Everglades, adapting well to the Everglades environment; they have also been wreaking havoc with the delicate ecosystem of the area; now, there is a new weapon in the fight against the Burmese python: dogs, trained to sniff out explosives, are being re-trained to locate the Burmese python

  • Rapid test strips detect swimming water contamination

    Water-testing technology has never been fast enough to keep up with changing conditions, nor accessible enough to check all waters; researchers have developed a rapid testing method using a simple paper strip that can detect E. coli in water within minutes; the new tool can close the gap between outbreak and detection, improving public safety

  • More efficient bioterrorism response plan

    In the event of a bioterror attack on a building (think: the 2011 anthrax attack on the offices of two Democratic Senators, Tom Daschle of South Dakota and Patrick Leahy of Vermont), the current approach to decontamination is to clean up the building until no pathogens can be detected; researchers suggest, however, that whether or not pathogens are found depends greatly upon how extensively the buildings are tested

  • PositiveID’s M-BAND fits the bill for $3 billion BioWatch program

    DHS’s $3.1 billion BioWatch program aims to place biosensors on top of utility poles and buildings in major American cities in order to detect bioterror attacks; PositiveID says its M-BAND solution is well positioned to be picked up by DHS for the program

  • Detection technology detects viruses, pathogens within 24 hours

    New detection technology could enable food safety professionals, law enforcement, medical professionals, and others to detect within twenty-four hours any virus or bacteria that has been sequenced and included among the array’s probes

  • MRIGlobal awarded $9 million to evaluate detection gear

    Kansas City company in a $9 million contract with the U.S. Army to test and evaluate equipment to identify chemical, biological, and radiological hazards in the field

  • Army scientists work to improve biothreat detection

    A married couple, both scientists working at the U.S. Army’s Edgewood Chemical Biological Center, one of forty-five Biosafety Level 3 labs in the United States; they collaborate on improving the ability of soldiers and first responders to detect, identify, and protect against potentially lethal biological threat agents
