• Using Radio Signals to Image Hidden and Speeding Objects

    Radio signals can create real-time images and videos of hidden and moving objects, helping firefighters find escape routes or victims inside buildings filled with fire and smoke. The technique could also be used to track hypersonic objects such as missiles and space debris.

  • Al Qaeda Renews Its Focus on Anti-Semitism and Attacking Israel

    For decades, Al Qaeda has used the issue of the Israeli-Palestinian conflict to rally support for themselves and unify disparate Islamist movements under its banner. The terrorist organization, however, has failed to carry out attacks against Israel or against Jews in other countries, leading to criticism of Al Qaeda by other jihadist groups. In recent weeks, Al Qaeda has directed an unusual portion of its propaganda toward encouraging attacks on Israel, Jewish institutions, and Jewish people.

  • Disaster Response and Mitigation in an AI World

    Accurately forecasting the movement of natural disasters—wildfires, floods, hurricanes, windstorms, tornados, and earthquakes—gives first responders a jump, allowing them to take measures to reduce damage, conduct advanced resource planning, and increase infrastructure restoration time.

  • Using Intelligent Drones for Search and Rescue

    Finding people lost (or hiding) in the forest is difficult because of the tree cover. People in planes and helicopters have difficulty seeing through the canopy to the ground below, where people might be walking or even laying down. The same problem exists for thermal applications—heat sensors cannot pick up readings adequately through the canopy. New drone technology helps search and rescue teams locate missing persons - even in dense forests.

  • In Launching of Anti-Crime Campaign, Biden Cites Old Data

    Ninety percent of guns found at crime scenes were sold by just 5% of gun dealers, President Joe Biden said Wednesday while unveiling his anti-crime initiative. But the 2000 ATF report has long been considered out of date, and irrelevant to today’s gun control debate. Supporters of the president’s initiative and gun-safety groups note that Biden had to rely on the 2000 report because there are no more recent ones: In 2003, Congress, under pressure from the gun lobby, passed legislation that prevents ATF from releasing the data.

  • Military and Defense-Related Supply Chains

    The military services, geographic combatant commanders, the Defense Logistics Agency (DLA), and other combat support agencies have different responsibilities and incentives, and their management of their supply chains reflect these differences. These incentives drive behavior that makes individual sense for the organizations, but might not result in overall effectiveness in supporting the needs of operating forces.

  • “Red Flag” Gun Laws and State Efforts to Block Local Legislation

    “Red flag” gun laws—which allow law enforcement to temporarily remove firearms from a person at risk of harming themselves or others—are gaining attention at the state and federal levels, but are under scrutiny by legislators who deem them unconstitutional. Legal scholars outline how such laws can reduce gun violence and still protect constitutional rights.

  • Iran Says It Foiled “Sabotage Attack” on Nuclear Building

    State media said the attack occurred near Karaj, some 40 kilometers west of Tehran. Iran has experienced a series of suspected sabotage attacks targeting its nuclear program in recent months.

  • Reflections on Iran’s Production of 60% Enriched Uranium

    As of about June 14, Iran had reportedly produced 6.5 kg 60% enriched uranium (hexafluoride mass) or 4.4 kg uranium mass only. Iran has produced 60% enriched uranium at an average daily rate of 0.126 kg/day since May 22. Iran’s activity must be viewed as practicing breakout to make enriched uranium for use in nuclear weapons.

  • Earlier Flood Forecasting Could Help Avoid Disaster in Japan

    In Japan, thousands of homes and businesses and hundreds of lives have been lost to typhoons. But now, researchers have revealed that a new flood forecasting system could provide earlier flood warnings, giving people more time to prepare or evacuate, and potentially saving lives.

  • Puerto Rico is Prone to More Flooding Than the Island is Prepared to Handle

    Puerto Rico is not ready for another hurricane season, let alone the effects of climate change, according to a new study that shows the island’s outstanding capacity to produce record-breaking floods and trigger a large number of landslides.

  • Inquiry Details 9 Missed Opportunities to Thwart 2017 British Concert Bombing

    Families of the 22 people who died in the 2017 terrorist bombing of a concert at Britain’s Manchester Arena are urging authorities to mount corporate manslaughter prosecutions against the firm responsible for security on the night of the attack and the company that runs the arena. Their demand came Thursday in the wake of the release of a damning official report into the terror attack that detailed nine missed opportunities to thwart the bombing of the Ariana Grande concert.

  • Foreign Disinformation Feeds U.S. Domestic Terrorism, Official Warns

    Newly unveiled efforts to combat a growing domestic terrorism threat in the United States will have to find a way to overcome a major obstacle: carefully crafted campaigns by foreign countries and terrorist groups to incite violence.

  • The Cold Comfort of Mutually Assured Destruction

    Decades after the end of the Cold War, scholars have begun to cast doubt on what has been taught about nuclear weapons in graduate schools – especially the notion of “nuclear revolution,” that is, that the condition of mutually assured destruction (MAD) would promote stability among the great powers. If nuclear weapons-based deterrence is not robust, but rather delicate, then “This is a book that the field of security studies will need to grapple with, since it overturns much of what scholars believe about nuclear deterrence,” Jasen Castillo writes.

  • Rare Earth Metals at the Heart of China’s Rivalry with U.S., Europe

    What if China were to cut off the United States and Europe from access to Rare Earth Elements (REEs), 17 minerals with unique characteristics which are essential to electric vehicles, wind turbines, drones, batteries, sophisticated military gear, and much more? This is a time of growing geopolitical friction among these three, and the United States and Europe want to change the current dependence on China, where, today, these minerals are largely extracted and refined.
