• Study Links Hard-Right Social Media with Incidents of Civil Unrest

    An increase in social media activity on “hard-right” platforms — those that purport to represent viewpoints not welcome on “mainstream” platforms — contributes to rightwing civil unrest in the United States, according to a new study. A new Yale-led study finds evidence that social media activity on hard-right platforms contributes to political unrest offline. “The magnitude of the effect we found is modest but two characteristics of social media and civil unrest caution against dismissing it,” said Yale sociologist Daniel Karell.

  • New Statistical Model Accurately Predicts Monthly U.S. Gun Homicides

    The United States experiences a staggeringly high rate of gun homicides, but accurately predicting these incidents – especially on a monthly basis – has been a significant challenge. A new methodology, overcoming limitations of official government data, could change that.

  • Using GSI Sensor Technology to Prediction Earthquakes

    Can nuclear physics improve the prediction of earthquakes? As part of a new project which aims to provide the foundation for a reliable early warning system for earthquakes in Europe, researchers are building a network of sensors measuring radon levels and other parameters in selected water sources in Europe might be able to detect earthquakes several days in advance.

  • Crisis-Preparation Lessons from COVID-19

    The early months of COVID-19 tested the UK’s highly regarded crisis management capabilities to their limit. The UK’s crisis management system was designed for, and practiced at, managing much shorter, more localized emergencies. There was no preparation for large-scale testing; no detailed planning for the economic consequences of a medical catastrophe; and no detailed plans in place for the possibility of school closures.

  • Investigators May Be Able to Use Household Dust as a Forensic Tool

    A new study found it is possible to retrieve forensically relevant information from human DNA in household dust. After sampling indoor dust from 13 households, the researchers were able to detect DNA from household residents over 90% of the time, and DNA from non-occupants 50% of the time. The work could be a way to help investigators find leads in difficult cases.

  • The Time to Prevent Shortfalls in Critical Materials Is Now

    By Doug Irving

    Rare earth elements are—despite their name—everywhere. They’re in your cellphone, your car, maybe even in a crown in your mouth. They’re in satellites, wind turbines, night-vision goggles, laser-guided missiles, and fighter jets. All of which makes China’s near-total domination of the rare earth market a matter of economic and national security concern.

  • A Balancing Act: What to Do About Taiwan

    If one of the world’s liberal democracies were to be taken over by a neo-totalitarian superpower, what would this imply for the future of freedom in Asia? What should we make of China’s claims about Taiwan? Should the U.S. replace its current policy of “strategic ambiguity” with a more explicit commitment to Taiwan’s defense?

  • Increase in Number of Nuclear Warheads In Arsenals of Nuclear Weapons States

    New report shows that the global arsenal of nuclear weapons available for use by the armed forces of the nine nuclear-armed states has increased. At the beginning of 2023, the nine nuclear-armed states had a combined inventory of approximately 12,512 nuclear warheads, of which 2,936 are retired and awaiting dismantlement. The remaining 9,576 nuclear warheads are available for use by the military, and have a collective destructive power of more than 135,000 Hiroshima bombs.

  • Germany's Balancing Act on Nuclear Weapons

    By William Noah Glucroft

    Germany is not a nuclear power, but it is part of U.S. nuclear strategy. In light of the war in Ukraine and the undoing of Cold War-era arms control, the country’s balanced approach is coming under more pressure.

  • The ‘Incelosphere’ and Incel Violence: A Worsening Problem?

    By Lewys Brace

    Should incel ideology be considered as extremist? Here is a summary of the research on how violent extremist language has increased over time as different online platforms have emerged and shutdown within the incel online ecosystem.

  • Major Foreign Terror Attack on U.S. “Almost Inconceivable” Now

    By Jeff Seldin

    Foreign terrorist groups, including some Islamic State and al-Qaida affiliates, may have the desire to launch major attacks on U.S. soil, but decades of counterterrorism work have made carrying out such an operation close to impossible at the moment, a top U.S. homeland security official said.

  • MI5 Increases Terror Threat Level in Northern Ireland to “Severe”

    There has been increased dissident republican activity in Northern Ireland, including the attempted murder of a senior police officer last month. MI5 believed it had dealt a major blow to the New IRA in 2020 when police arrested nine suspected leaders of the organization, but the New IRA appears to have regrouped.

  • Underwater Nuclear Drone: North Korea’s Nuclear Madmen

    By David Albright

    One remarkably irresponsible claim by Kim Jong Un is North Korea’s announced testing of an underwater drone that it states can carry a nuclear weapon, able to infiltrate enemy waters and create a deadly radioactive plume of water. Such a detonation could severely contaminate ships and port cities with intense radioactive fallout mixed with water.

  • How Many Guns Are There in the U.S.?

    By Jennifer Mascia

    We’ve heard for years that there are more guns in the U.S. than people, but a precise accounting remains elusive. Federal legislation that would track gun sales or establish a nationwide handgun registry has been proposed — to much resistance from the gun lobby. Pinpointing the number of guns in circulation could help us better understand the relationship between gun sales and gun violence.

  • Guns Now Kill More Children and Young Adults Than Car Crashes

    For the past few decades, motor vehicle crashes were the most common cause of death from injury— and the leading cause of death in general—among children, teenagers, and young adults in the U.S. But now, firearms exceed motor vehicle crashes as the leading cause of injury-related death for people ages one to 24.
