• Fashionable detector-on-a-ring detects chemical, biological threats

    Wearable sensors are revolutionizing the tech-world, capable of tracking processes in the body, such as heart rates. They’re even becoming fashionable, with many of them sporting sleek, stylish designs. But wearable sensors also can have applications in detecting threats that are external to the body.

  • $300K challenge to uncover emerging biothreats

    DHS S&T has launched the Hidden Signals Challenge, a $300,000 prize competition that seeks concepts for novel uses of existing data to uncover emerging biothreats. The Challenge calls upon data innovators from a wide variety of fields to develop concepts that will identify signals and achieve timelier alerts for biothreats in our cities and communities.

  • Finding confirms Assad’s systematic use of chemical weapons in Syria

    Samples from an attack in northern Syria on 30 March “prove the existence of sarin,” a deadly nerve agent, the director of the Organization for the Prohibition of Chemical Weapons (OPCW) said on 4 October. The attack injured dozens, but it did not kill anybody. So why is this finding important? Because it confirms a pattern of sarin use by the government of Bashar al-Assad.

  • U.S. not prepared to identify perpetrators of biological attacks: Expert panel

    When violent attackers use biological agents to inflict harm, not only must law enforcement attribute the crime to the correct perpetrator, they must also identify the pathogens used and their sources exactly and quickly. That was the focus of a special meeting last week hosted by the Blue Ribbon Study Panel on Biodefense.

  • Detecting nuclear materials used in dirty bombs

    Radiological material falling into the wrong hands is a constant security concern for governments around the world. Border agencies must scan incoming vehicles and freight for radioactive material, which is a challenging task, as huge volumes of both move across borders each day. Imperial College London’s physicists have developed two devices for detecting nuclear materials.

  • Congressional amendments restore Maryland BioLab4 funding

    Members of the Maryland congressional delegation attached amendments to the Homeland Security and Defense Department authorization bills to prevent the closure of the National Biodefense Analysis and Countermeasures Center (NBACC) at Fort Detrick, Maryland. President Trump’s budget for 2018 had eliminated funding for NBACC as part of cutting the budget of DHS Science and Technology Directorate (S&T) by 28 percent. At the end of May 2017, the research center received a letter from DHS stating that the facility’s closing procedures should start on 1October, with anticipated decommissioning by 30 September 2018.

  • Soft target, hard problem: Keeping surface transportation secure

    Maintaining security on the U.S. surface transportation systems takes significant resources and manpower, both which tend to be in short supply. What if there were a way to detect potential threats in bags or on persons from the moment they entered the subway? What if there was a way to know the path individuals take as they move through the system, and to relay that information to transit police in real-time?

  • S&T, the Pentagon changing K-9 bomb detection

    DHS S&T Detection Canine Program partnered with the Pentagon Force Protection Agency (PFPA) to assist in developing a training initiative to add person-borne improvised explosive device (PBIED) detection capabilities to their canine teams. Traditionally, dogs sniff out “left-behind” bombs, but Sunny and the other members of his K-9 unit are also trained to pick up explosive scents on a person or any moving target.

  • World unprepared to deal with the effects of a thermonuclear attack

    The world is not prepared to deal with the devastating effects of a thermonuclear attack, says an University of Georgia’s Cham Dallas. He said that the development of a hydrogen bomb by North Korea is a transformative event, especially from the point of view of the medical and public health response to a thermonuclear detonation.

  • Israel destroys Syrian chemical weapons facility

    The Israeli air force Thursday morning attacked and destroyed a chemical arms plant in in Syria. Media reports say that Israel had destroyed the Scientific Studies and Researchers Center facility near the city of Masyaf in central Syria, where Syria has been working on developing of chemical weapons. This was the first time a high-level Israeli official has confirmed the scope of Israel’s attacks. Thursday’s attack was the first Israeli strike against a military facility in Syria since a cease-fire was reached in southern Syria in July (there have been, however, low-level border skirmishes between Israel and units of Assad army). Israel bitterly complained that the cease-fire agreement negotiated between the United States and Russia ignored acute Israeli security concerns.

  • Assad used chemical weapons more than two dozen times: UN

    The regime of Bashar al-Assad in Syria has used chemical weapons on more than two dozen occasions since the outbreak of the civil war six years ago, including in April’s deadly attack on Khan Sheikhoun, a UN war crimes investigation revealed on Wednesday. In their 14th report since 2011, which includes the most conclusive findings to date from investigations into chemical weapons attacks in the Syrian civil war, the UN investigators said they had documented a total of 33 attacks.

  • Radiation analysis software from Sandia Lab helps emergency responders

    When law enforcement officers and first responders arrive at an emergency involving radiation, they need a way to swiftly assess the situation to keep the public and environment safe. Having analysis tools that can quickly and reliably make sense of radiation data is of the essence. Sandia National Laboratories developed a tool called InterSpec, available for both mobile and traditional computing devices, can rapidly and accurately analyze gamma radiation data collected at the scene.

  • Detecting carriers of dirty bombs

    The threat of terrorism in Europe has been on the rise in recent years, with experts and politicians particularly worried that terrorists might make use of dirty bombs. Researchers have developed a new system that will be able to detect possible carriers of radioactive substances, even in large crowds of people. This solution is one of the defensive measures being developed as part of the REHSTRAIN project, which is focused on security for TGV and ICE high-speed trains in France and Germany.

  • Why we should start worrying about nuclear fallout

    Since North Korea’s recent missile tests, and Sunday’s underground nuclear test, the possibility of nuclear warfare looms larger than it has in more than five decades. Nearly thirty years after the cold war ended, are we prepared to face such a challenge? How would large-scale nuclear attacks affect the world today? “During the cold war, the United States, the Soviet Union, and several European countries built networks of fallout shelters — but even at their peak, these would not have effectively protected the majority of citizens,” says one expert. Nor is radioactive fallout the only problem, because “the damage from mass fires triggered by nuclear bombs has been radically and persistently underestimated.”

  • Harnessing AI to catch disease fast

    Up to 27,000 microbiology laboratories around the world could benefit from a ground-breaking automation technology. The Automated Plate Assessment System (APAS) can automatically screen microbiology culture plates for the presence of various disease-causing pathogens, revolutionizing the workflow in modern microbiology labs. The smart software uses artificial intelligence to analyze microbial growth in much the same way as a microbiologist would, but with faster and more consistent results.
