• New fabric coating could neutralize chemical weapons, save lives

    Chemical weapons are nightmarish. In a millisecond, they can kill hundreds, if not thousands. But, in a new study, scientists report that they have developed a way to adhere a lightweight coating onto fabrics that is capable of neutralizing a subclass of these toxins — those that are delivered through the skin. The life-saving technique could eventually be used to protect soldiers and emergency responders.

  • Helping explosive detection canine teams across the U.S.

    Dogs are uniquely suited to sniffing out explosives – their sense of smell is more than a million times stronger than a human’s. Harnessing this natural ability to help law enforcement identify explosives requires specialized training and testing. Many detection canine teams, however, have limited access to critical training materials and limited time to establish rigorous training scenarios. DHS S&T’s Detection Canine Program has developed an initiative to support these needs for the nation’s more than 4,000 explosives detection canine teams.

  • Extracting useful insights from a flood of data is hard to do

    A mantra of these data-rife times is that within the vast and growing volumes of diverse data types, such as sensor feeds, economic indicators, and scientific and environmental measurements, are dots of significance that can tell important stories, if only those dots could be identified and connected in authentically meaningful ways. Getting good at that exercise of data synthesis and interpretation ought to open new, quicker routes to identifying threats, tracking disease outbreaks, and otherwise answering questions and solving problems that previously were intractable.

  • How can we better protect crowds from terrorism?

    As the recent terrorist attacks in the United Kingdom painfully show, the odds are in favor of terrorists. All they have to do is succeed once, no matter how many times they try. For public safety professionals to be fully successful, they have to prevent 100 percent of the terror attempts. It’s a number to aspire to, but even the most experienced countries fighting terror – such as Israel and the U.K.– can’t measure up to this standard. These days, it’s necessary to consider any place where crowds congregate as vulnerable “soft targets” for the attackers. Community policing, though, could help. Community policing means using the community as a resource to minimize the spread of radical ideologies. By informing and supporting law enforcement through proactive partnerships, citizens can become key players and reliable partners in what some call “co-produced” public safety. These strategies won’t provide absolute security. But they will help minimize attacks and get us closer to that golden 100 percent standard.

  • Eight minutes on London Bridge: years of training led to lightning police response

    Eight minutes. That is the length of time from the start of the London Bridge attack to the three terrorists being killed by armed police. The Metropolitan Police Service is rightly being heralded for the speed, courage and effectiveness of its members in ending a terrorist atrocity. But the success in their response which prevented more people from being injured and killed is, besides individual bravery, about learning from previous terrorist attacks, training, and resources. The terrorism situation in the United Kingdom is clearly in flux. At the moment, the only pattern when it comes to terrorist attacks is that there is no pattern. Nonetheless, members of the police will continue to prepare to deal with worst-case scenarios, based on previous attacks, that they hope will never materialize.

  • Cybersecurity on the fly

    When we think of cybersecurity, we think of applying protection measures to our desktop computers such as installing antivirus programs and using passcodes and pin numbers. Just like our computers, aircraft systems are vulnerable and are not exempt from a cyber-attack. If hacked, some examples of possible cyber effects on aircraft systems can be anything from breakdowns in communication and navigation systems to the more critical systems such as collision avoidance and life support systems.

  • Hackers could take control of missiles on U.K. subs, start a “catastrophic” nuclear war: Report

    Britain’s Trident nuclear weapons deterrent program consists of four Vanguard-class submarines, each carrying up to sixteen Trident II D5 ballistic missiles with a nuclear warhead. Hackers could take control of nuclear weapons-carrying Vanguard-class submarines and start a “catastrophic” nuclear war, a new report warns. The 38-page report warns a security breach could “neutralize operations, lead to loss of life, defeat or perhaps even the catastrophic exchange of nuclear warheads (directly or indirectly).” Des Browne, former U.K. Defense Secretary, said: “To imagine that critical digital systems at the heart of nuclear weapon systems are somehow immune or can be confidently protected by dedicated teams of network managers is to be irresponsibly complacent.”

  • Diplomat: Hezbollah is now more powerful than most NATO members

    The Iran-backed terrorist group Hezbollah is “now more militarily powerful than most North Atlantic Treaty Organization members,” a former Israeli ambassador to the United Nations says. In violation of UN Resolution 1701, which was adopted to end the 2006 Lebanon War, Hezbollah has acquired an estimated 150,000 missiles — more than the combined arsenals of 27 NATO nations — with a range capable of striking “anywhere in Israel” and the ability to “launch 1,500 of them a day,” Ron Prosor wrote.

  • Coroners unable to agree on cause of death, or whether a case merits inquest

    Around 507,000 people die in England and Wales every year. Nearly half (45 percent) of these deaths are reported to coroners, who investigate those believed to be violent, unnatural, or of unknown cause, to find out the identity of the deceased and the circumstances of his or her death. A former top detective turned university researcher has published his findings that coroners in England and Wales are seemingly unable to agree on what caused a person’s death or whether it merits an inquest, even when faced with identical case information.

  • Face Recognition Challenge seeks better face-identification software

    Have you developed software to identity faces in general web photographs? Can your software verify that a face in one photograph is the same as in another? The Intelligence Advanced Research Projects Activity (IARPA) announced the launch of the Face Recognition Prize Challenge (FRPC). The challenge aims to improve biometric face recognition by improving core face recognition accuracy.

  • What it takes to be a forensic fingerprint examiner?

    Being a forensic examiner seems glamorous on TV. But working in a crime lab requires long hours of intense focus that are anything but action-packed. This is especially true for fingerprint examiners, who must focus on minute visual details that would leave most people cross-eyed. It’s not a job for everyone.Experts are developing tests to help identify people with the pattern-matching skills needed for analyzing fingerprints.

  • Using antimalarial compound to detect bloodstains

    As seen on crime shows, investigators use a combination of luminol and other substances to light up bloodstains at crime scenes. But now, researchers report that combining luminol with artemisinin, a natural peroxide and antimalarial treatment, reduces the risk of false positives compared to the traditional method.

  • No funds for California's earthquake early-warning system in Trump's proposed budget

    The Trump administration’s proposed budget would eliminate federal funding for an earthquake early warning system being developed for the U.S. West Coast. Critics say that if the relevant clauses in the budget proposal become law, the long-planned seismic warning effort will be killed. Scientists say the withdrawal of federal funds would likely end the early-warning project, which aims to send smartphone tremor alert messages to West Coast residents.

  • Israel to install earthquake early-warning system

    Israel has selected Ottawa, Canada-based Nanometrics to build an earthquake early-warning system in Israel. The alert system will give a 10-to-30-second alert of an impending earthquake. The system’s success depends on the distinction between two types of waves an earthquake generates — P waves (for primary) and S waves (for secondary). P waves are very fast, traveling through rock at between four and seven kilometers per second, and are thus the first waves to arrive at a recording station following an earthquake. An S-wave has a shearing motion that makes the rock vibrate perpendicular to its path. This movement slows the S-wave, so that it travels at two to five kilometers per second, or about half the speed of the P-wave. It is S waves which are almost entirely responsible for the damage and destruction associated with earthquakes.

  • The rising homegrown terror threat on the right

    Dealing effectively with far-right violence requires that we treat its manifestations as domestic terrorism. I consider domestic terrorism a more significant threat than the foreign-masterminded variety in part because it is more common in terms of the number of attacks on U.S. soil. The number of violent attacks on U.S. soil inspired by far-right ideology has spiked since the beginning of this century, rising from a yearly average of 70 attacks in the 1990s to a yearly average of more than 300 since 2001. I would argue that this trend reflects a deeper social change in American society. The iceberg model of political extremism, initially developed by Israeli political scientist Ehud Shprinzak, can illuminate these dynamics. Murders and other violent attacks perpetrated by U.S. far-right extremists compose the visible tip of an iceberg. The rest of this iceberg is under water and out of sight. It includes hundreds of attacks every year that damage property and intimidate communities. The significant growth in far-right violence in recent years is happening at the base of the iceberg. Changes in societal norms are usually reflected in behavioral changes. It is thus more than reasonable to suspect that extremist individuals engage in such activities because they sense that their views are enjoying growing social legitimacy and acceptance, which is emboldening them to act on their bigotry.
