• WiFi can detect weapons, bombs, chemicals in bags

    Ordinary WiFi can easily detect weapons, bombs and explosive chemicals in bags at museums, stadiums, theme parks, schools and other public venues, according to a new study. Researchers  demonstrated how this low-cost technology could help security screening at public venues like stadiums, theme parks and schools.

  • What are coastal nuclear power plants doing to address climate threats?

    Flooding can be catastrophic to a nuclear power plant because it can knock out its electrical systems, disabling its cooling mechanisms and leading to overheating and possible meltdown and a dangerous release of radioactivity. At least 100 U.S., European and Asian nuclear power stations built just a few meters above sea level could be threatened by serious flooding caused by accelerating sea-level rise and more frequent storm surges. More than 20 flooding incidents have been recorded at U.S. nuclear plants since the early 1980s. A number of scientific papers published in 2018 suggest that climate change will impact coastal nuclear plants earlier and harder than the industry, governments, or regulatory bodies have expected, and that the safety standards set by national nuclear regulators and the IAEA are out of date and take insufficient account of the effects of climate change on nuclear power.

  • U.S. imposing new sanctions on Russia for spy poisoning in U.K.

    The State Department says it will be implementing new sanctions on Russia as punishment for the March 2018 poisoning of former spy Sergei Skripal and his daughter Yulia on British soil. The new sanctions, which will go into effect on 22 August, target export licenses of sensitive U.S. technologies and industrial equipment, such as electronics, calibration equipment, and gas turbine engines. Russia will also be given 90 days to comply with other demands, including allowing international inspectors into the country to ensure that no chemical or biological weapons exist there. If Moscow does not comply with the demands, a second round of sanctions could further downgrade diplomatic relations with Russia, or even restrict flights by Russian air carrier Aeroflot.

  • High- and low-tech solutions for bomb disposal

    To ensure bomb techs are on the cutting edge of technology as they address evolving threats, DHS S&T created the Response and Defeat Operations Support (REDOPS) program. REDOPS connects the 466 bomb squads of varying sizes and budgets across the country with the tools and information they need to perform their duties better, faster and more safely. They look at a variety of sources—including the commercial marketplace, responder communities and international partners—for high- and low-tech solutions.

  • Better decisions during a radiological emergency

    Whether a catastrophe is natural or man-made, emergency managers need to respond quickly with the optimal solution. Making decisions on the fly can be difficult, which is why significant planning must go into a disaster response strategy. Many conversations need to happen, and they need to cover a range of possible scenarios. The Radiation Decontamination tool Rad Decon was developed to facilitate those very discussions during a radiological emergency.

  • New nerve gas detector made of a smartphone and Lego bricks

    Researchers have designed a way to sense dangerous chemicals using, in part, a simple rig consisting of a smartphone and a box made from Lego bricks, which could help first responders and scientists in the field identify deadly and difficult-to-detect nerve agents such as VX and sarin.

  • Scavenger hunt for simulated nuclear materials

    Competing in a fictitious high-stakes scenario, a group of scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) bested two dozen other teams in a months-long, data-driven scavenger hunt for simulated radioactive materials in a virtual urban environment. The competition platform was also built and managed by Lab researchers.

  • Smarter, safer bridges with Sandia sensors

    In 2016, more than 54,000 bridges in the U.S. were classified as “structurally deficient” by the Federal Highway Administration’s National Bridge Inventory. This means about 9 percent of U.S. bridges need regular monitoring. Researchers outfitted a U.S. bridge with a network of eight real-time sensors able to alert maintenance engineers when they detect a crack or when a crack reaches a length that requires repair.

  • Nuclear waste: The cost to Americans is in the billions

    Since the Manhattan Project officially began in 1942, the United States has faced ever-increasing stores of nuclear waste. Stanford’s Rodney Ewing says that the U.S. failure to implement a permanent solution for nuclear waste storage and disposal is costing Americans billions of dollars a year.

  • Preparing for quick radiation diagnostic test in case of a nuclear disaster

    Researchers are attempting to create a better diagnostic test for radiation exposure that potentially could save thousands of lives. A new study compiled a list of genes reported to be affected by external ionizing radiation (IR), and assessed their performance as possible biomarkers that could be used to calculate the amount of radiation absorbed by the human body.

  • Winners announced in $1.5 million Passenger Screening Algorithm Challenge

    DHS S&T and TSA the other day announced the eight winners of the Passenger Screening Algorithm Challenge. The prize competition solicited new automated detection algorithms from individuals and entities that can improve the speed and accuracy of detecting small threat objects and other prohibited items during the airport passenger screening process.

  • British defense chief says Russian “attack” led to woman's death

    The residue of the poisonous chemical Novichock, which Russian intelligence agents used in early March in Salisbury, U.K., in an assassination attempt of a former Russian spy and his daughter, poisoned two residents from neighboring Amesbury, killing one of them. “The simple reality is that Russia has committed an attack on British soil which has seen the death of a British citizen,” Defense Secretary Gavin Williamson said.

  • British defense chief says Russian “attack” led to woman's death

  • Novichok: the deadly story behind the nerve agent

    Earlier this week, in the town of Salisbury, England, two people were poisoned accidentally by traces of the nerve agent Novichok, which Russian intelligence operatives used on 4 March 2018 in an attempt to assassinate former Russian intelligence officer Sergei Skripal, along with his daughter Yulia. Alastair Hay’s article was written on 20 March 2018. Why do these lethal chemical agents exist at all?

  • Omitted details from UN report implicate Syria, Iran in use of chemical weapons

    Details implicating Syria and Iran for a series of chemical weapons attacks in January and February were removed from a UN report that had been released last week. A UN commission investigating war crimes during the seven-year-old Syrian civil war uncovered evidence of six chemical weapons attacks perpetrated by the Assad regime between January and 7 April this year.
