• Climate-Fueled Wildfires Lead to Rethink on Fire Tactics

    Climate change is making wildfires more frequent and more destructive, and long-time firefighting strategies are no longer working. Scientists are calling for a radical rethink of how we fight wildfires.

  • Do Armed Guards Prevent School Shootings?

    Roughly a third of parents with school-age kids are very or extremely worried about gun violence at their child’s school, according to a 2022 survey by The Pew Research Center. The same Pew survey found that roughly half of U.S. parents think armed security in schools is an effective response. Do armed guards — sometimes called school resource officers or school police officers — are actually a deterrent to gun violence and mass shootings?

  • AI-Controlled Weapons Should Be Banned from the Battlefield: Experts

    AI expert says autonomous systems being used in the current Ukraine conflict need to be prohibited in the same way as chemical and biological weapons. “I’m quite hopeful that we will, at some point, decide that autonomous weapons also be added to the lists of terrible ways to fight war like chemical weapons, like biological weapons. What worries me is that in most cases, we’ve only regulated various technologies for fighting after we’ve seen the horrors of them being misused in battle,” he says.

  • Using Hydrogen to Power Disaster Relief

    A new vehicle will not only get emergency responders safely to the site of an emergency, but also directly provide power at the scene for up to 72 hours as they assess next steps. And it does all this running on hydrogen—a much more sustainable solution for our environment.

  • As Competition with China Heats Up, Japan Turns to Africa for Critical Minerals

    Demand for such minerals is expected to grow sharply in the coming years. There are, however, supply constraints, as only a limited number of countries produce them. Tokyo has signed agreements with a number of African countries as competition with China for key raw materials and minerals heats up.

  • Nuclear Engineer Uses Machine Learning on Weapons Testing Images to Understand Fallout

    After WWII, the U.S. wanted to better understand what happened after a nuclear weapon was detonated. Researchers conducted tests in the southwestern U.S. and the Pacific Ocean and recorded those experiments on film. Scientists used the original reel-to-reel films to manually measure data from the blasts. Today, nuclear forensic scientists combine modern computational techniques with the historical records of nuclear tests to obtain precious insights into the physics of these type of events, which are otherwise hard to study experimentally.

  • How Reliable and Robust Is Human Ability to Recognize Suspicious Activity?

    Security procedures at large public venues and transportation hubs rely upon vigilant and engaged security officers who are tasked, in part, with timely and appropriate responses to suspicious behavior of potential hostile actors. But how capable are individuals at detecting suspicious behavior?

  • Study Confirms Link Between Concealed Carry Weapons and Gun Homicide Rates

    Concealed guns significantly impact homicide rates and public safety, according to a Rutgers study that found an increase in homicides based on the number of concealed carry weapons licenses issued.

  • Develop 3D Printable Robots for Search-and-Rescue Operations

    Researchers are developing a small and flexible 3D-printed robots with integrated fluidic circuits that can be rapidly fabricated for specific disasters. These robots can aid rescue efforts by exploring areas that pose potential hazards to humans or are otherwise inaccessible, including earthquake debris, flooded regions, and even nuclear accident sites.

  • Incels: The Ideology, the Threat, and a Way Forward

    Misogynist ideology, beyond individual criminal behavior, has fueled violence against women worldwide. A new report explores the phenomenon of ‘incels’ (a portmanteau of ‘involuntary’ and ‘celibate’) and the misogynistic ideology that underpins this global community of men that has become a thriving internet subculture.

  • Better Resources to Mitigate Explosive Threats

    Every second counts when responders encounter an explosive device, and critical decisions must be made quickly in order to neutralize the threat while also ensuring the security of civilians, property, and the responders themselves.

  • The New Technology Which Is Making Cars Easier for Criminals to Steal, or Crash

    There is much talk in the automotive industry about the “internet of vehicles” (IoV). This describes a network of cars and other vehicles that could exchange data over the internet in an effort to make transportation more autonomous, safe and efficient. There are many benefits to IoV, but some of these systems might also make our vehicles prone to theft and malicious attack, as criminals identify and then exploit vulnerabilities in this new technology. In fact, this is already happening.

  • Anti-Zionism Mutates into Anti-Semitism on the Political Left

    Expressions of anti-Israel bias from left-leaning political organizations in several European democracies have devolved into anti-Semitism and even violent attacks against local Jewish communities.

  • Fame-seeking Mass Shooters More Likely to Plan “Surprise” Attacks; Novelty of Their Locations, Targets Brings Added Fame

    Mass shooters pursuing fame often plan their attacks as “surprises,” carefully crafting them in ways that set them apart from previous incidents, which makes them uniquely challenging to prevent. Fame-seekers — unlike those mostly motivated by personal grievance or revenge — planned their crimes around the novelty of the location and targets.

  • Changing State Perception of Nuclear Deterrence in Japan and South Korea

    Japan and South Korea face the combined threat of an increasingly assertive China and a progressively more destabilizing North Korea, not to mention a Russia which has resumed its role as a Pacific power. The US has enhanced its engagement with its East Asian partners in nuclear planning and consultation mechanisms. The prospects of indigenous nuclear weapons acquisition by Japan and South Korea, though, cannot be ruled out.
