• Planned burns can reduce wildfire risks, but expanding use of ‘good fire’ isn’t easy

    Prescribed burns can decrease the potential for some of the large, severe fires that have affected western states in recent years. As scholars of U.S. forest policy, collaborative environmental management and social-ecological systems, we see them as a management tool that deserves much wider attention.

  • Rapid DNA technology ID’ed California wildfire victims

    Amid the chaos and devastation of a mass casualty evet, medical examiners often provide closure as they identify victims in the aftermath, but their ability to do this quickly can vary depending on the size, scope, and type of disaster. Such challenges were the case following the Camp Fire wildfire that killed eighty-five people and devastated communities in Paradise, California, in the fall of 2018. S&T’s Rapid DNA technology became the first resort as it provided identifying information in under two hours when dental records and fingerprints weren’t available.

  • Abundance of DNA evidence insufficient to prevent wrongful convictions

    As we enter an era in which DNA evidence is routinely used in criminal investigations, errors that led to wrongful convictions—including mistakes later corrected with DNA tests—may seem to be fading into history. This, however, is not true, says an expert.

  • The darker side of the dark web: Weapons trade

    Debates over gun regulations make headlines across the world, but there’s an underground operation for weapons that has drawn very little attention – until now. Researchers crept into the dark web to investigate how firearms are anonymously bought and sold around the world.

  • “Hardened” schools are not safe from gun violence

    Hardening of schools seems to be a questionable endeavor, given the dearth of evidence regarding effectiveness, says an expert. A comprehensive review of the literature from 2000 to 2018 regarding school firearm violence prevention, found no programs or practices with evidence that they reduced such gun violence.

  • How Columbine became a blueprint for school shooters

    When twelve students and one teacher were killed in Littleton, Colorado twenty years ago, it not only became what at the time was the worst high school shooting in U.S. history. It also marked when American society was first handed a script for a new form of violence in schools. Since the 1999 tragedy at Columbine High School, we identified six mass shootings and forty active shooter incidents at elementary, middle or high schools in the United States. In twenty – or nearly half – of those forty-six school shootings, the perpetrator purposely used Columbine as a model.

  • S&T seeking partners for first responder technology R&D

    DHS S&T said it was inviting industry, academia, laboratories, and the innovation community to submit white papers related to twelve first responder technology funding opportunities. S&T said that each of the twelve topic areas “represent technology needs identified by responders themselves, and we are seeking the best partners to turn these needs into solutions.”

  • Climate change: Our greatest national security threat?

    The climate century is here: the earth is warming, humans are to blame, and we must take immediate action now to prepare for climate change’s massively disruptive consequences. Mark Nevitt writes in Just Security that No longer can climate change be categorized solely as an environmental issue—it is a grave threat to national security. Indeed, it may be the threat. While there are many national security challenges facing the nation and the world, climate change is an aptly described “super wicked” problem that exacerbates and accelerates already existing threats.

  • Sensing earthquakes in a new way to help improve early warning systems

    Every year earthquakes worldwide claim hundreds or even thousands of lives. Forewarning allows people to head for safety and a matter of seconds could spell the difference between life and death. Researchers demonstrate a new earthquake detection method — their technique exploits subtle telltale gravitational signals traveling ahead of the tremors. Future research could boost early warning systems.

  • Novel compact antenna for communicating where radios fail

    A new type of pocket-sized antenna could enable mobile communication in situations where conventional radios don’t work, such as under water, through the ground and over very long distances through air. The 4-inch-tall device could be used in portable transmitters for rescue missions and other challenging applications demanding high mobility.

  • Knife-crime assault data to help forecast fatal stabbings

    Knife crime data from a 12-month period could be used to help forecast the London neighborhoods most likely to suffer a fatal stabbing the following year, according to latest research.

  • Studying Perry Mason to combat “innocence fatigue”

    Forensic science historian Professor Ian Burney is studying the influence of Erle Stanley Gardner, creator of renowned TV attorney Perry Mason, in a bid to reveal the roots of the fascination with stories about wrongful criminal conviction. Burney hopes the study will help better understand some of the challenges facing today’s worldwide “innocence projects.”

  • Israeli air strike destroys Iranian missile production, storage facility in Syria

    Satellite images released Sunday by ImageSat International (ISI) showed the impact of an airstrike, blamed on Israel, on a missile base in Syria on Saturday evening that reportedly killed Iranian personnel. Israeli analysts say that recent Israeli air strikes in Syria probably would not have passed without public Russian comment had Israel and Russia not reached an understanding designed to reduce possible friction and improve early warning between Israeli and Russian armed forces operating in Syria.

  • As Russia expanded its Arctic Sea presence, U.S. observers see veiled threat

    Some U.S. military officials and legislators have expressed concern that Washington isn’t paying enough attention to Russia’s military entrenchment in the region. They say the Department of Defense Arctic Strategy, last updated in 2017, largely got overlooked in the more all-encompassing National Defense Strategy, the main U.S. military strategy document signed by the chairman of the Joint Chiefs of Staff.

  • It is safer to be a cop today than 50 years ago

    There is no doubt that policing is a dangerous profession. But is it safer to be a cop today than it was fifty years ago? Yes, according to a study that analyzed police officer deaths (felonious and non-felonious) in the United States from 1970 to 2016.
