• Scanning social media as a tool for biosurveillance

    DHS is considering observing and scanning social media Web sites to collect and analyze health-related data which could help identify outbreaks of infectious diseases and other public health and national security risks

  • Improving the sensitivity of airport security screening

    Scientists are reporting a simple way to improve the sensitivity of the test often used to detect traces of explosives on the hands, carry-ons, and other possessions of passengers at airport security screening stations; scientists concluded that swab fabrics could be improved to collect smaller amounts of explosives by peppering them with hydroxyl, phenyl and amine functional groups

  • Powerful debugging program to help U.S. nuclear deterrence

    Lawrence Livermore National Laboratory (LLNL) researchers have used the Stack Trace Analysis Tool (STAT), a highly scalable, lightweight tool to debug a program running more than one million MPI processes on the IBM Blue Gene/Q (BGQ)-based Sequoia supercomputer; LLNL plans to use Sequoia’s impressive computational capability to advance understanding of fundamental physics and engineering questions that arise in the National Nuclear Security Administration’s (NNSA) program to ensure the safety, security, and effectiveness of the U.S. nuclear deterrent without testing

  • New fluorescence technology pinpoints oil leaks at sea

    Cambridge Consultants uses fertility monitor technology in oil leak early warning system; the company has built an oil spill detection technology platform which is capable of detecting the natural fluorescence of even tiny amounts of oil in or on water

  • Experts: German nuclear exit offers economic, environmental benefits

    Following the accident at the Fukushima Daiichi Nuclear Power Station in 2011, the German government took the nation’s eight oldest reactors offline immediately and passed legislation which will close the last nuclear power plant by 2022; this nuclear phase-out had overwhelming political support in Germany; elsewhere, many saw it as “panic politics”; a new collection of studies shows that the nuclear shutdown and an accompanying move toward renewable energy are already yielding measurable economic and environmental benefits

  • Approaches to international consequence management for CBRNE incidents

    The National Research Council (NRC) of the National Academy of Sciences, through a grant sponsored by NIST’s Office of Law Enforcement Standards (OLES), is organizing an effort to understand the metrics and measures that are needed to develop standards of response that will support the basic capabilities of a country or region to respond to a chemical, biological, radiological, nuclear, or explosive (CBRNE) incident

  • Technology used in BioWatch could not detect pathogens, issued false alarms

    The BioWatch program was created to detect the release of pathogens in the air as part of a terrorist attack, but scientists say that the program is unable to detect lethal germs because the system uses defective components; these components often set off false alarms; for example, BioWatch sensors issued fifty alarms between 2003 and 2008, but scientists and security authorities never had enough confidence in the BioWatch system to evacuate an area or take other emergency steps

  • TSA replaces backscatter scanners with millimeter wave scanners at some airports

    TSA is replacing some backscatter scanners at large U.S. airports with millimeter wave scanners; backscatter scanners were criticized for violating travelers’ privacy, and risking travelers’ health by emitting high levels of radiation

  • Twenty-year anniversary of U.S. last full-scale nuclear test

    The first U.S. nuclear test, code named Trinity, took place in southern New Mexico forty-seven years earlier, on 16 July 1945; in all, the United States conducted 1,030 nuclear tests – the last one, code-named Divider,  took place twenty years ago, on 23 September 1992

  • Los Alamos lab accelerates shipment of nuclear waste to permanent storage site

    Los Alamos National Laboratory broke its own records in the first year of accelerated shipping effort of nuclear waste from the Lab to permanent disposal facilities located twenty-six miles outside of Carlsbad, New Mexico

  • Different technologies aim to replace dogs as explosives detectors

    Bomb-sniffing dogs are the best and most popular way for airport security quickly to detect anyone planning to bring explosives to an airport; scientists are trying to change that; Dr. Denis Spitzer and his colleagues, for example, are working on a sensor that will detect vapors of TNT and other explosives in very faint amounts; the device they are trying to create would replace dogs as the top bomb detecting method in the field

  • DARPA seeking tools for identifying hidden explosives at standoff

    The threat to U.S. soldiers from improvised explosive devices (IEDs) is as varied as the makers of IEDs are resourceful in how they design and conceal the explosives; interdisciplinary teams needed to develop proof-of-concept demonstrations of technology for identifying presence of embedded explosives in opaque, high-water-content substances

  • Mice genetically modified to detect landmines

    In another advancement in explosives detection, scientists have genetically modified mice to enable them to sniff out landmines; the GM mouse, known as MouSensor, may one day become a significant tool to help deal with the dangerous legacies of past wars

  • CNN commentator complains of inappropriate TSA pat down

    A CNN commentator says she was molested by TSA agents when a routine security pat-down ended with federal agents repeatedly touching her private parts and refusing her a public screening

  • Y-12 Nuclear Complex’s uranium processing facility to be redesigned

    Weeks after the inadequacy of security measures at the Y-12 Nuclear Complex came to light — an 82-year old nun and her two senior citizen colleagues eluded the facility’s fences and security to spend a few hours on the site’s grounds and spray-paint anti-nuclear slogans on its walls – criticism is directed at the design shortcomings of a new uranium processing facility; among other things, the roof of the new facility will have to be raised by thirteen feet because the designers did not take into account the size of the equipment the new facility will house
