• Israel: Assad used chemical weapons on 27 March in a Damascus neighborhood

    President Bashar Assad’s military used chemical weapons two weeks ago in a neighborhood east of Damascus against opposition forces, a senior Israeli defense official said yesterday (Monday). Syrian rebels reported of two instances in which Assad’s forces used chemical weapons recently, both about two weeks ago and both in Damascus neighborhoods, and the Israeli confirmation was the first information provided by outside intelligence sources to back up the rebels’ claims.

  • Chemical plant security measure moves forward in the House

    The House Homeland Security Committee and the House Energy and Commerce Committee are making progress on legislation meant to extend DHS’s Chemical Facility Anti-Terrorism Standardsprogram, which helps secure commercial chemical plants from terrorist attacks. Several attempts by the House Homeland Security Committee to extend the program have failed due to disagreements with the House Energy and Commerce Committee, which also oversees the matter.

  • Cutting edge, animatronic mannequin to test CB protective suits, equipment

    See video

    The U.K. Defense Science and Technology Laboratory (DSTL) has taken delivery of a new robotic mannequin which will be used to test chemical and biological (CB) protective suits and equipment for the U.K.’s Armed Forces. The “Porton Man” uses state of the art technology and is able to walk, march, run, sit, kneel and even lift its arms as if to sight a weapon just like an infantry soldier.

  • West Virginia chemical spill degrades air, water quality

    In the more than two months since the 9 January chemical spill into West Virginia’s Elk River, new findings reveal the nature of the chemicals that were released into the water and then into the air in residents’ houses. The lack of data motivated researchers to take on essential odor-related research that went beyond their National Science Foundation Rapid Response Research grant to better understand the properties of the chemical mixture called crude 4-methylcyclohexane methanol, the major component in the crude mix of the spilled chemicals into the Elk River

  • Israel State Comptroller says some IDF units unprepared for chemical attack

    Israel’s State Comptroller Joseph Shapira on Wednesday harshly criticized the Israel Defense Force (IDF) for not having sufficient number of gas masks for one of its branches. The comptroller levelled his criticism in the unclassified portion of his discussion of defense issue in his annual report on government performance. In February, Israel has discontinued the distribution of gas masks to the general population, and the dismantling of Syria chemical weapons arsenal has led some Israeli defense experts to question the need for Israel to continue and invest in defensive measures against chemical weapons attacks.

  • Determining long-term effects of West Virginia chemical spill

    A chemical mixture called crude 4-methylcyclohexane methanol (MCHM) is used during the separation and cleaning of coal products. More than 10,000 gallons of the chemical leaked from a storage tank near Charleston, West Virginia, and entered the river upstream of a water-treatment plant on 9 January. The drinking water of more than 300,000 West Virginians was contaminated. Water restrictions began to be lifted on 13 January, but residents are still detecting the telltale odors of MCHM. Virginia Tech faculty engineers and students are unravelling fundamental chemical and health properties of MCHM.

  • “Encouraged” bacteria cleaning up more effectively after oil spills

    Bioremediation is nature’s way of cleaning up. Plants, bacterial decomposers, or enzymes are used to remove contaminants and restore the balance of nature in the wake of pollution incidents. What is surprising is that given the right kind of encouragement, bacteria can be even more effective. Researchers in Norway have achieved surprising results by exploiting nature’s own ability to clean up after oil spills.

  • Compact UV laser for biological, chemical detection

    In addition to detecting chemical and biological agents in the field — or at home to protect against mass terror attacks — UV lasers have many other uses. The new class of UV lasers envisioned by DARPA’s Laser UV Sources for Tactical Efficient Raman (LUSTER) program is expected to be of use for a broad range of applications such as point-of-need medical diagnostics, advanced manufacturing, and compact atomic clocks.

  • Libyan Islamists tried to ship mustard gas to Syrian rebels

    Libyan officials report that they have recently apprehended several members of a Libyan Muslim extremist militia planning to ship chemical weapons to anti-Assad rebels in Syria. Colonel Mansour al-Mazini of the Libya army said that the Islamists had been caught with a container of mustard gas. The gas was confiscated by Libyan soldiers.

  • After failing 5 February deadline, Syria wants 100-day extension to remove chemicals

    After missing the 5 February deadline to have all its chemical weapons removed from its territory, Syria has submitted a new 100-day plan for their removal. The international group monitoring the operation says the completion of the removal can be accomplished in less time than that. The Organization for the Prohibition of Chemical Weapons (OPCW) executive committee met on Friday in The Hague to discuss the joint OPCW and UN mission at a time when there is a growing international frustration with Syria over its failure to live up to its commitments.

  • Tracking spilled oil

    A newly developed computer model holds the promise of helping scientists track and predict where oil will go after a spill, sometimes years later. Scientists developed the model as a way of tracking the movement of sand and oil found along the Gulf of Mexico since the Deepwater Horizon oil spill. The new tool can help guide clean-up efforts, and be used to aid the response to future oil spills.

  • Floods caused lead poisoning in U.K. cattle

    Massive floods in England and Wales have forced thousands to evacuate their homes and destroyed railways and roads. Scientists say the U.K. floods of recent years carry yet another danger with them: lead poisoning. Silage cut from fields soon after they were inundated in the 2012 floods and then fed to cattle raised the lead levels in the animals, killing some of them. Blood samples taken from cattle showed that all of them had lead levels beyond the safe limit for human consumption. An autopsy carried out on one of the casualty animals found lead concentrations 79 times the safe level in its kidney. The contaminated material is thought to originate from historical metal mining in the area. Scientists say a number of river catchments throughout England and Wales face a similar risk.

  • Most of Libya’s chemical weapons destroyed

    When Libya joined the Chemical Weapons Convention in December 2003, it reported to the Organization for the Prohibition of Chemical Weapons (OPCW) that it was operating three chemical-weapons production facilities, and that it had produced a total of twenty-five tons of sulfur mustard gas, 3,563 bombs with warfare agents, and 1,390 tons of precursor materials. Over the next eight years, these chemical weapons stock were systematically destroyed under international supervision. The work was halted between February and November 2011 – the beginning of the rebellion against Qaddafi and his departure from power – and resumed in early 2012. OPCW announced than on 26 January 2014, work on destroying Libya’s mustard gas has been completed. The question is whether the Qaddafi regime was truthful in its 2003 declaration – or whether there are still stocks of chemical agents stashed somewhere in desert caches.

  • NSF rapid response research grants to fund study of West Virginia chemical spill

    On 9 January 2014, crude 4-methylcyclohexane methanol (MCHM), a chemical primarily used to clean coal, leaked from a storage tank near Charleston, West Virginia, and bled into a river upstream of a water-treatment plant. As a result, about 15 percent of the state’s residents were advised not to drink the water. Better to understand the properties of the chemical that contaminated the drinking water, and the plumbing and water-treatment systems surrounding the area, the National Science Foundation (NSF) has awarded Rapid Response Research (RAPID) grants to research teams at three universities. These grants also will provide STEM learning opportunities for undergraduate and graduate students on the research teams.

  • Growing body of evidence connects lead’s deleterious effects to criminal behavior

    Violent crimes had reached an all-time high in the United States in the early 1990s, but by the end of the decade, the homicide rate had plummeted by more than 40 percent. Many theories were offered to explain this dramatic decline, but a new explanation is gaining credence: the banning of lead from gasoline and paint in the early 1970s. Babies born post-ban were exposed to far less lead – with its proven contribution to lowering IQ and causing attention problems and antisocial tendencies — and twenty years on, these babies became young adults who committed fewer crimes than their predecessors.
