• Polymers help minimize fuel explosions and fires from accidents and terrorist acts

    When an act of terrorism or a vehicle or industrial accident ignites fuel, the resulting fire or explosion can be devastating. On Tuesday, scientists described how lengthy but microscopic chains of polymers could be added to fuel to significantly reduce the damage from these terrifying incidents without impacting performance.

  • Turning incident scenes into virtual 3D models

    When officers arrive at a crime or crash scene, they have to spend a lot of time looking for evidence, processing it, taking photos of it, and documenting. To help make this process more efficient, the Department of Homeland Security’s (DHS) Science and Technology Directorate (S&T) has teamed up with the Israeli Police to invest in a new tool.

  • Improving canine detection of explosives

    The Department of Homeland Security (DHS) Science and Technology Directorate (S&T) has awarded $564,988 in funding to Auburn University for two research and development (R&D) projects designed to improve the effectiveness and efficiency of canines trained to detect explosives.

  • In disasters, Twitter users with large networks get out-tweeted

    New study shows that when it comes to sharing emergency information during natural disasters, timing is everything. The study on Twitter use during hurricanes, floods and tornadoes offers potentially life-saving data about how information is disseminated in emergency situations, and by whom. Unlikely heroes often emerge in disasters, and the same is true on social media.

  • Killer robots already exist, and they’ve been here a very long time

    The question is not so much whether we should use autonomous weapon systems in battle – we already use them, and they take many forms. Rather, we should focus on how we use them, why we use them, and what form – if any – human intervention should take.

  • Israel’s Carbyne, RapidSOS partner to improve 911 calls

    Dialing 911 in an emergency is something that we’ve all been instructed to do since childhood. And old-fashioned, simple dialing is what most of us are still doing, even in an age of far more sophisticated technology. Next-gen public safety tech company will provide call takers with more informative real-time data to help first responders locate and treat callers.

  • California hospitals to pay billions for seismic safety upgrades

    California hospitals would need to make substantial investments—between $34 billion and $143 billion statewide—to meet 2030 state seismic safety standards, according to a new report.

  • Recaptured Italian former militant Battisti admits 1970s murders

    Former communist militant Cesare Battisti has admitted four murders carried out in the 1970s, during Italy’s so-called “Years of Lead,” weeks after being jailed in Italy for the killings that were part of a failed bid to spark a far-left revolution.

  • Mapping out virtual world for U.S. military

    When the U.S. military interviewed more than 100 experts about conflicts in Syria and Iraq, the resulting intelligence was so extensive that analysts joked about needing executive summaries for the executive summaries. Scientists at Argonne National Laboratory convert complex data into 3D digital visualizations to provide spatial and geographic context.

  • Russia sends military planes to Venezuela

    Russia, a key ally of under-siege President Nicolas Maduro of Venezuela, sent two planes with  military supplies and troops to shore up the Maduro regime. Russia had already sent two Tu-160 strategic bombers to Venezuela in December to support Maduro. Three months ago the two nations held military exercises in Venezuela.

  • Chances of UN banning killer robots looking increasingly remote

    The Campaign to Stop Killer Robots warns chances of achieving a U.N. treaty banning the development, production and use of fully autonomous lethal weapons, also known as killer robots, are looking increasingly remote. Experts from some 80 countries are attending a weeklong meeting to discuss the prospect of negotiating an international treaty.

  • Detecting radioactive material remotely

    Physicists have developed a powerful new method to detect radioactive material. By using an infrared laser beam to induce a phenomenon known as an electron avalanche breakdown near the material, the new technique is able to detect shielded material from a distance. The method improves upon current technologies that require close proximity to the radioactive material.

  • More mass shooting in states with permissive gun laws

    States with more permissive gun laws and greater gun ownership have higher rates of mass shootings, and a growing divide is emerging between states with restrictive versus permissive gun laws. According to a new study, researchers found that in most years permissive states had higher mass shooting rates compared to restrictive states.

  • Dunford: Google’s work with China “challenges” U.S. military advantage

    The top U.S. military officer has called out U.S. technology giant Google for its artificial intelligence venture in China, saying it “creates a challenge” in maintaining a U.S. military advantage over the Chinese.

  • Satellite technology detects, and may prevent, genocide

    Many of the world’s worst human rights abuses, including genocides, occur in areas that are difficult to observe. “Smallsat” — short for small satellite — technology can detect human rights abuses and violations. The information collected by this technology provides evidence that can be used to corroborate refugee accounts of atrocities in international courts.
