• More rigorous approach to training of explosive-detecting dogs

    With a sense of smell much greater than humans, dogs are considered the gold standard for explosive detection in many situations. But that does not mean there is no room for improvement. In a new study, scientists report on a new, more rigorous approach to training dogs and their handlers based on real-time analysis of what canines actually smell when they are exposed to explosive materials.

  • Scintillating discovery at Sandia Labs

    Taking inspiration from an unusual source, a Sandia National Laboratories team has dramatically improved the science of scintillators — objects that detect nuclear threats. According to the team, using organic glass scintillators could soon make it even harder to smuggle nuclear materials through America’s ports and borders. The Sandia Labs team developed a scintillator made of an organic glass which is more effective than the best-known nuclear threat detection material while being much easier and cheaper to produce.

  • Immigration does not raise crime: Studies

    Immigration has no effect on crime, according to a comprehensive examination of fifty-one studies on the topic published between 1994 and 2014. The meta-analysis is the first on the relationship between immigration and crime. The reviewed studies most frequently found no relationship between immigration and crime. But among those that did find a correlation, it was 2.5 times more likely that immigration was linked to a reduction in crime than an increase.

  • House panel: DOD to regard climate change as a direct threat to U.S. national security

    During Wednesday’s markup of the Fiscal Year 2018 National Defense Authorization Act (NDAA), the Emerging Threats and Capabilities Subcommittee of the House Armed Services Committee passed by voice vote an amendment which acknowledges that “climate change is a direct threat to the national security of the United States.” The amendment instructs the Department of Defense to “ensure that it is prepared to conduct operations both today and in the future and that it is prepared to address the effects of a changing climate on threat assessments, resources, and readiness.”

  • Upgrades at Sandia’s Tonopah Test Range help weapons testing

    It’s been a challenge for Sandia National Laboratories’ Tonopah Test Range to keep decades-old equipment running while gathering the detailed information required for twenty-first century non-nuclear testing. Over the past several years, the 60-year-old Nevada range has changed the analog brains in instruments to digital, moved to modern communications systems, upgraded telemetry and tracking equipment and updated computing systems.

  • As adversaries bolster their capabilities, U.S. naval technology must keep pace

    U.S. Navy leaders say that as adversaries move quickly to advance their technological capabilities, the pace of technology development and delivery in the U.S. Navy and Marine Corps must accelerate in order to maintain the technological edge for U.S. warfighters. “We have a great opportunity to supercharge the engine of naval research,” says Chief of Naval Research (CNR) Rear Adm. David Hahn. “From discovery to deployment, innovative U.S. naval technology has been essential to mission success. We’re going to ensure that continues.”

  • U.S. warns Assad over planned chemical attack

    The United States has charged that the Assad regime was preparing to launch another large-scale chemical weapons attack on Sunni Syrians — warning that the Syrian regime would “pay a heavy price” if it went ahead with the attack. The White House, in a statement released late Monday, said that the United States had noticed Syrian military preparations similar to those the Syrian military had undertaken ahead of the 4 April chemical attack which killed eighty-seven Syrian civilians.

  • Growing opposition in Germany to new surveillance measures

    In the aftermath of the Christmas 2016 market attacks in Berlin last December, the German government written several sweeping surveillance and data retention laws, which were narrowly passed by the Bundestag. Many of these laws will go into effect 1 July. Civil libertarians, opposition parties, and some security experts have criticized the new powers as diminishing privacy without adding much to security. These politicians and NGOs say that a spate of security measures just go too far.

  • IDF chief of staff: Hezbollah has forces in “every 3rd or 4th house” in Southern Lebanon

    The IDF’s chief of staff said on Tuesday that the Iran-backed terrorist group Hezbollah has a presence in “every third or fourth house” in southern Lebanon, in violation of United Nations Security Council Resolution 1701, which called for the removal of all armed groups from the area. Lt. Gen. Gadi Eisenkot said that Hezbollah was ensconced in some 240 villages and towns in southern Lebanon, and remains the most immediate threat to Israel.

  • Gun policy preferences across racial groups

    In the wake of recent mass shootings in Alexandria, Virginia, and elsewhere in the United States, a new study looks at factors that drive support for gun control among whites, Latinos, and blacks. The researchers found support for all forms of gun control is stronger among Latinos and blacks than whites. For example, 74 percent of blacks and 61 percent of Latinos, but only 55 percent of whites support an assault weapons ban.

  • Decision to defund the Earthquake Early Warning system criticized

    The Trump administration’s decision to defund the Earthquake Early Warning system is being criticized by experts. The “administration’s failure to fund the Earthquake Early Warning (EEW) system threatens this vital program and potentially the lives of hundreds or even thousands of people on the West Coast from California to Alaska,” says one expert.

  • At least 600 U.K high-rises have combustible cladding installed

    British Prime Minister Theresa May told the House of Commons on Thursday that investigators have found combustible cladding on “a number” of publicly owned tower blocks similar to Grenfell Tower. “Shortly before I came to the chamber, I was informed that a number of these tests have come back as combustible,” she said. The prime minister’s said her office estimated that 600 high-rise buildings in England have cladding similar to Grenfell Tower.

  • Cuomo pardons 9/11 ground zero worker facing deportation

    Governor Andrew Cuomo has pardoned an undocumented immigrant who worked on to help clean up ground zero after the 9/11 terrorist attacks. The pardon would help Carlos Cardona fight deportation proceedings. Cardona was convicted in 1990, when he was 21-year old, for attempting to sell a controlled substance.

  • How U.S. gun control compares to the rest of the world

    The shooting in Virginia that wounded House Majority Whip Steve Scalise, as well as the shooting in a San Francisco UPS facility that left four dead on the very same day, have generated – yet again – the standard set of responses in the wake of a mass shooting in the United States. The details of any such tragedy often emerge slowly, but a few points can be made. While deaths from mass shootings are a relatively small part of the overall homicidal violence in America, they are particularly wrenching. The problem is worse in the United States than in most other industrialized nations. And it is getting worse.

  • Helping troops fight in coastal urban environments

    As nation-state and non-state adversaries adapt and apply commercially available state-of-the-art technology in urban conflict, expeditionary U.S. forces face a shrinking operational advantage. New program aims to develop advanced battle management/command and control tools and a comprehensive interactive virtual environment to test novel concepts for future expeditionary combat operations.
