• Specialized gas detection helps prevent nuclear weapons proliferation

    Researchers aim to design a system capable of sensing, from among the loud signals of a lot of gases, the weak signals from specific gases which are signs of nuclear weapons proliferation. The researchers believe their gas correlation technique will prove ideal for a simple, inexpensive sensor to monitor those few illusive gases. This could change how the nation thinks about monitoring the spread of nuclear weapons. Instead of single-point measurements taken with expensive sensors deployed after someone suspects a problem, 24/7 continuous monitoring could find leaks early.

  • Lawmakers, citing shortcomings, threaten funding for chemical plant safety program

    Heads of three congressional panels urge DHS secretary Janet Napolitano to take to correct shortcomings in the Chemical Facilities Anti-Terrorism Standards (CFATS) program. “As the authorizers and appropriators of this program, we write to you to express serious reservations about continuing to extend CFATS funding without evidence of substantial programmatic improvement,” the three chairmen write in their letter to Napolitano. The lawmakers pointed to flaws in the program’s risk evaluation system, compliance hurdles, implementation delays, and the failure of the program to identify vulnerable facilities.

  • U.S., South Korea teaming up for bioterrorism exercise

    Officials from the United States and South Korea were in Seoul, South Korea last month for the third annual joint anti-bioterrorism exercise in Seoul. Around eighty U.S. officials and between 120 and 130 South Korean military officials participated in the tabletop exercise.

  • Japan to restart nuclear power plants

    Japan’s fifty nuclear power plants were taken off-line in the wake of the 2011 Fukushima nuclear disaster, but the government Prime Minister Shinzo Abe, which took office in December, said it was planning to restart Japan’s nuclear power generation program.

  • Russia: Syria rebels used sarin gas

    Vitaly Churkin, Russia’s UN ambassador, announced at a UN news conference Tuesday that scientific analysis by Russian labs of a suspected chemical weapons attack in Syria on 19 March concluded the attack probably had been carried out by rebels using sarin nerve gas of “cottage industry” quality. He said the gas was delivered by a crudely made missile.

  • Oil-devouring microbe communities a mile deep in the Gulf

    The Deepwater Horizon explosion on 20 April 2010, caused the largest marine oil spill in history, with several million barrels of crude oil released into the Gulf of Mexico over the course of three months. Soon after the spill began, a massive oil slick was visible from orbiting satellites, yet once the underwater gusher was sealed, obvious traces of the crude oil disappeared much sooner than nearly all observers predicted. Some of the oil evaporated; some was skimmed off. Microbes “ate” much of the oil as well.

  • Study shows TSA security screeners are methodical, not slow

    A study by Duke University, partially funded by DHS, found that TSA screeners may be slower than amateur screeners when it comes to performing visual searches, but the TSA screeners are better at detecting contraband.

  • Researchers highlight problem of legacy mercury in the environment

    Researchers have published evidence that significant reductions in mercury emissions will be necessary just to stabilize current levels of the toxic element in the environment. So much mercury persists in surface reservoirs (soil, air, and water) from past pollution, going back thousands of years, that it will continue to persist in the ocean and accumulate in fish for decades to centuries, they report.

  • Highly portable X-ray imaging system developed

    Los Alamos National Laboratory and Tribogenics have developed the MiniMAX (Miniature, Mobile, Agile, X-ray) camera to provide real-time inspection of sealed containers and facilities.MiniMAX is an alternative to the large, expensive, and fixed facilities presently required for security inspections using X-ray imaging. The complete MiniMAX portable radiography system weighs less than five pounds.

  • Chechen Islamic terrorists threaten February 2014 Winter Olympics in Sochi, Russia

    Doku Umarov, a leading Chechen Islamic rebel, on Wednesday issued a call to Islamist militants throughout the North Caucasus to begin and plan for attacks to disrupt the February 2014 Winter Olympics which will be held in the Black Sea resort of Sochi. Security experts say that securing the games would be a daunting task.

  • Protecting drinking water systems from deliberate contamination

    The importance of water and of water infrastructures to human health and to the running of the economy makes water systems likely targets for terrorism and CBRN (chemical, biological, and radionuclide) contamination. Reducing the vulnerability of drinking water systems to deliberate attacks is one of the major security challenges. An international project has developed a response program for rapidly restoring the use of drinking water networks following a deliberate contamination event.

  • Radiation dose passengers receive from airport scanners is low

    An independent task force examining X-ray backscatter scanners at LAX airport determines that that people absorb less radiation from airport X-ray backscatter scanner than they do while standing in line waiting for the scan.

  • Rapid, on-site detection of illegal cooking oils

    In recent years, illegal cooking oil incident in China caused serious food safety risks. Researchers have developed two rapid and convenient colorimetric detection methods of illegal cooking oils based on phase transfer technology.

  • Two men charged with planning an “X-ray weapon’’ to kill Muslim enemies of U.S., Israel

    Two men from upstate New York were charged Wednesday with a scheme to build an X-ray weapon to kill Muslim enemies of the United States and Israel. They planned the weapon to kill the designated targets with lethal radiation, and some of the targets were to be killed in their sleep. The indictment says the two wanted to build a powerful X-ray device that could be placed in a truck and driven near a target. The driver would park, leave the area, and activate the device, “killing human targets silently and from a distance with lethal doses of radiation.”

  • U.K. nuclear disaster exercise reveals worrisome lapses in emergency response

    Up to six times a year, U.K. nuclear weapons are transported in heavily guarded convoys between production facilities in Aldermaston and Burghfield in Berkshire, where the nuclear bombs are manufactured, and the Royal Naval Armaments Depot at Coulport on Loch Long in Argyll. The trips are required because scientists must regularly examine the 200 Trident missile warheads in order to make sure they are operationally reliable and properly maintained. Every three years, the U.K. Ministry of Defense (MoD) conducts a drill aiming to test how various agencies respond to an accident involving the convoy carrying the nuclear warheads. An internal report on the last drill notes many problems in the response to the simulated accident, including five-hour wait for weapons experts, confusion over radiation monitoring, and ambulance crews refusing to take contamination victims to hospitals.
