• Strong evidence that Syrian government used chemicals in attacks on three cities

    Evidence strongly suggests that Syrian government helicopters dropped barrel bombs filled with cylinders of chlorine gas on three towns in Northern Syria in mid-April 2014, Human Rights Watch said earlier this week. These attacks used an industrial chemical as a weapon, an act banned by the international treaty prohibiting chemical weapons that Syria joined in October 2013. The Syrian government is the only party to the conflict with helicopters and other aircraft.

  • Metal-organic framework quickly destroys toxic nerve agents

    First used 100 years ago during the First World War, deadly chemical weapons continue to be a challenge to combat. Scientists have developed a robust new material, inspired by biological catalysts, which is extraordinarily effective at destroying toxic nerve agents that are a threat around the globe. The material, a zirconium-based metal-organic framework (MOF), degrades in minutes one of the most toxic chemical agents known to mankind: Soman (GD), a more toxic relative of sarin. Computer simulations show the MOF should be effective against other easy-to-make agents, such as VX.

  • Meals served to Turkey’s president Erdogan tested for poison

    Turkish president Recep Tayyip Erdogan has implemented strict new measures to protect his personal security. One of these measures: Every meal he is served – both at home and abroad — is rigorously tested to make sure it does not contain any poisonous materials inserted by a would-be assassin. Dr. Cevdet Erdol, Erdogan’s personal physician, said that a special food analysis laboratory will be built at Erdogan’s lavish presidential palace to make sure all his food is safe to eat. “It’s usually not through bullets that prominent figures are being assassinated these days,” Erdol told the Hurriyet newspaper on Tuesday.

  • Color-changing film detects chemical weapons

    In today’s world, in which the threat of terrorism looms, there is an urgent need for fast, reliable tools to detect the release of deadly chemical warfare agents (CWAs). Scientists are reporting progress toward thin-film materials that could rapidly change colors in the presence of CWAs — an advance that could help save lives and hold aggressors accountable.

  • Turning deadly chemical warfare agents into harmless soil

    Destroying chemical warfare agents in bulk is a challenge for the military and international community. Current methods of eradication, such as incineration or hydrolysis, create toxic waste which requires further processing. The logistics required to transport large stockpiles from storage to a disposal site can be risky and expensive. DARPA is seeking portable system that turns stockpiles of chemical warfare agents into dirt or other safe organic compounds without generating hazardous waste.

  • New acoustic sensor for chemical, biological detection

    Testing for ovarian cancer or the presence of a particular chemical could be almost as simple as distinguishing an F sharp from a B flat, thanks to a new microscopic acoustic device that has been dramatically improved by scientists at the Argonne National Laboratory. The device, known as a surface acoustic wave (SAW) sensor, detects frequency changes in waves that propagate through its crystalline structure. This makes it ideal for detecting the presence of chemicals or biomarkers present in a liquid or gas.

  • Microrockets fueled by water neutralize chemical and biological warfare agents

    With fears growing over chemical and biological weapons falling into the wrong hands, scientists are developing microrockets to fight back against these dangerous agents. Scientists point out that titanium dioxide is one of the most promising materials available for degrading chemical and biological warfare agents. It does not require harsh chemicals or result in toxic by-products. There is no way, however, actively to mix titanium dioxide in waterways, so scientists have been working on ways to propel titanium dioxide around to accelerate the decontamination process without the need for active stirring.

  • Light frequencies help sniff out deadly materials from a distance

    Spectroscopic chemical sensing, which measures the frequency of light absorbed or scattered from a substance to help determine its molecular identity, can be used to detect traces of biological and chemical agents and residue from explosive materials. New program aims to develop chip-sized, optical frequency combs which accurately identify even tiny traces of dangerous biological and chemical substances several football fields away.

  • Effective, inexpensive method to detect natural gas pipeline leaks

    Major leaks from oil and gas pipelines have led to home evacuations, explosions, millions of dollars in lawsuit payouts, and valuable natural resources escaping into the air, ground and water. Scientists say they have developed a new software-based method that finds leaks even when they are small, which could help prevent serious incidents — and save money for customers and industry.

  • Assad retains secret caches of chemical weapons: Israeli intelligence

    Despite committing to dismantle and give up its chemical weapons – Syria was in possession of the world’s largest chemical weapons stock — President Bashar al-Assad’s regime still maintains a “residual” chemical weapons capacity, consisting of a few tons of the proscribed materials. Israel’s intelligence community has concluded that the Assad regime has decided to keep this reduced, but still formidable, chemical weapons capability, and has successfully concealed it from the inspectors of the UN chemical weapons watchdog who, a few weeks ago, have declared the chemical disarmament of Syria to be officially complete. Israeli defense officials believe that these sarin gas weapons would likely be deployed if the Assad regime faced an imminent threat to its survival. The Syrian regime is continuing to use chemical weapons which were not covered by the U.S.-Russian chemical weapons disarmament agreement, especially chlorine gas.

  • Improved gas mask protects U.S. soldiers against lethal attacks

    Choking. Watering eyes. Blistering skin. Convulsions. These are all symptoms of a chemical weapons attack that can lead to imminent death. The lethality of such attacks, most recently the one in Syria in August 2013, can send tremors across the globe. For U.S. Army soldiers, however, chemical weapons present a real danger on the battlefield, and one that requires the most advanced technology to keep them safe. Scientists and researchers at the U.S. Army Edgewood Chemical Biological Center (ECBC) have been working toward better protective equipment, including the iconic gas mask.

  • UN report indicates Syrian army used chlorine in April attacks on rebel-held villages

    The Organization for the Prohibition of Chemical Weapons (OPCW) said that a toxic chemical, probably chlorine, was used as a weapon to attack three Syrian villages in April. The agency investigators did not specify who had launched the chlorine attacks, but the full report, which so far has been shared only with governments, leaves little doubt that the Syrian government was responsible for the attacks.

  • Electric bugs harnessed to detect water pollution

    Scientists have developed a low-cost device that could be used in developing countries to monitor the quality of drinking water in real time without costly lab equipment. The sensor contains bacteria that produce a small measurable electric current as they feed and grow. The researchers found that when the bacteria are disturbed by coming into contact with toxins in the water, the electric current drops, alerting to the presence of pollutants in the water.

  • Convergence of chemistry and biology raises concerns about designer toxins

    The convergence of chemistry and biology is providing major benefits to humankind, particularly in health care, alternative energy sources, and in environmental control – and when combined with other advances, particularly in nanotechnology, it is also being exploited in developing improved defensive countermeasures against chemical and biological warfare agents. This convergence, however, has also raised concerns that biotechnology could be applied to the production of new toxic chemicals, bioregulators, and toxins. A new report from OPCW says that the potential for scaling up biological processes for large scale production of chemicals of concern is still limited, but biomediated processes might still be effective for producing weaponizable quantities of toxins which are lethal to humans in microgram or lower dosage.

  • OPCW says Syria has completed handover of chemical weapons, but some are skeptical

    Syria handed over the remaining 100 tons of toxic material to the Organization for the Prohibition of Chemical Weapons (OPCW) last Monday. The final consignment, publicly delayed, consisted of about 8 percent of the total 1,300 tons that the country is believed to have possessed. Despite the celebratory mood, many in the West look at the Syrian and OPCW announcements skeptically due to conflicting information.
