• Living sensor may prevent environmental disasters from fuel spills

    The Colonial Pipeline, which carries fuel from Texas to New York, ruptured last fall, dumping a quarter-million gallons of gas in rural Alabama. By the time the leak was detected during routine inspection, vapors from released gasoline were so strong they prevented pipeline repair for days. Now, scientists are developing technology that would alert pipeline managers about leaks as soon as failure begins, avoiding the environmental disasters and fuel distribution disruptions resulting from pipeline leaks.

  • Nerve agent was placed in former spy’s BMW ventilation system: U.S. intel

    The former Russian spy Sergei Skripal and his daughter, Yulia, may have been exposed to a deadly nerve agent through his car’s ventilation system, ABC News reports. The two remain in critical condition in hospital after being exposed to the nerve agent novichok in Salisbury, in the U.K., two weeks ago. ABC News reported that intelligence officials had said the “dusty” substance used was likely placed in the ventilation system of the BMW Skripal was driving.

  • U.K.'s Johnson says Putin probably behind ex-spy attack; Kremlin lashes out

    British Foreign Secretary Boris Johnson has said it is “overwhelmingly likely” that Russian President Vladimir Putin made the decision to use a highly toxic chemical against a former double agent in England. “We have nothing against the Russians themselves. There is to be no Russophobia as a result of what is happening,” Johnson said on 16 March6, nearly two weeks after former spy Sergei Skripal and his daughter, Yulia, were exposed to what British authorities say was a potent nerve agent developed in the Soviet Union. “Our quarrel is with Putin’s Kremlin, and with his decision — and we think it overwhelmingly likely that it was his decision — to direct the use of a nerve agent on the streets of the U.K., on the streets of Europe for the first time since the Second World War,” Johnson said.

  • French expert says novichok toxin is “clearly a direct link to Russia”

    Novichok, the toxic nerve agent that British authorities believe was used in the near-fatal poisoning of former spy and retired Russian military intelligence officer Sergei Skripal, is a powerful substance that is exceedingly difficult to manufacture. This is why a growing number of chemical weapons experts say it is highly likely that only a government could have the technology and infrastructure to make it. And given that the Soviet Union, in the 1980s, was the only state known to have produced it, that has led many experts to conclude that Russian intelligence was behind Skripal’s poisoning.

  • Expanding real-time radiological threat detection to include other dangers

    Advanced commercially available technologies—such as additive manufacturing (3-D printing), small-scale chemical reactors for pharmaceuticals, and CRISPR gene-manipulation tools—have opened wide access to scientific exploration and discovery. In the hands of terrorists and rogue nation states, however, these capabilities could be misused to concoct chemical, biological, radiological, nuclear, and high-yield explosive (CBRNE) weapons of mass destruction (WMD) in small quantities and in form factors that are hard to detect. DARPA’s SIGMA+ program aims to create additional sensors and networks to detect biological, chemical, and explosives threats.

  • DTRA awards British university $1.1 million for improved radiation detectors

    The University of Surrey has been awarded $1.1 million by the U.S. Defense Threat Reduction Agency (DTRA) to research new types of nanomaterials that produce high efficiency radiation detectors for use in nuclear security. The project will develop materials that are used as highly sensitive radiation detectors.

  • Britain deploys specialist troops in city where ex-Russian spy collapsed

    Britain has deployed specialist troops to remove potentially contaminated objects from the site where former Russian spy Sergei Skripal and his daughter were found unconscious after a suspected nerve-agent attack. Skripal, 66, and his daughter Yulia, 33, have been in hospital since they were found on a bench outside a shopping center in the southern English city of Salisbury on 4 March.

  • Toxicologist: Lab with “military capability” likely made poison used on Russian ex-spy

    British investigators have announced that a “nerve agent” was used in an attempt to murder Russian former spy Sergei Skripal in Salisbury on 4 March. But they have not specified what nerve agent was used in the attack. Alastair Hay, a professor of environmental toxicology and a member of the British government’s advisory group on chemical warfare agents, said about the likely source of the toxic substance: “I think it’s more a case in which we are talking about a military capability. If you are a diligent chemist, you will find procedures for making sarin and tabun and various other chemical agents. But there’s the complexity in making it and how efficient the reaction is. And, of course, there is the risk of exposure in making something, too. So containment to make sure that the laboratory person is not exposed is absolutely crucial. So I think, really, what one is looking at here is probably more a military-type manufacture. But again, we just have to wait and see.”

  • Nerve agents: what are they and how do they work?

    The first nerve agents were invented by accident in the 1930s when researchers were trying to make cheaper and better alternatives to nicotine as insecticides. In their search, German scientists made two organic compounds containing phosphorus that were very effective at killing insect pests. However, they soon discovered that, even in minuscule amounts, the substances caused distressing symptoms in humans exposed to them. The two substances – too toxic to be used as commercial insecticides in agriculture – became known as tabun and sarin. Since then, other nerve agents have been developed, but much less is known about them, although they are thought to work in broadly the same way. Unlike street drugs, nerve agents cannot be made in your kitchen or garden shed, on account of their toxicity, even in tiny amounts. Synthesis of nerve agents requires a specialist laboratory, with fume cupboards. As more details emerge from the case of former Russian spy Sergei Skripal, we’ll know more about the precise substance used and how it should be tackled. Either way, nerve agents are horrendously lethal and chemical warfare is an obscene use of chemicals.

  • Suspected nerve-agent attack in U.K. an “appalling, reckless crime”

    The substance used on 4 March to injure an ex-Russian spy ad his daughter was a nerve agent – but the British police say it was rarer than sarin or VX nerve agents, thus making the involvement of Russian state labs in the production of the substance certain. A spokesman for British Prime Minister Theresa May said the attack on Skripal and his daughter was an “appalling and reckless crime.” Skripal’s son Sergei, 44, died on a visit to Russia last year under mysterious circumstances.

  • U.K. counterterrorism unit takes over probe into Russian ex-spy's illness

    Britain’s counterterrorism police took over the investigation into the sudden and severe illness of former Russian spy Sergei Skripal and his daughter as media reported that Skripal’s son died last year of unknown causes on a visit to Russia. Scotland Yard announced that its counterterrorism unit would take charge due to the case’s “unusual circumstances” after Foreign Secretary Boris Johnson warned that any involvement of a foreign government in the incident would not go “unpunished.”

  • Name your poison: Exotic toxins fell Kremlin foes

    The sudden illness in Britain of a Russian former spy has drawn comparisons with another poisoning in the United Kingdom – the 2006 assassination by Vladimir Putin’s agents of Russian former-spy-turned-Kremlin-critic Aleksandr Litvinenko. In using various poisons – some of them esoteric — to have his critics and adversaries killed inside Russia and abroad, Putin is continuing a storied KGB tradition. Here is a closer, if brief, look at some of the poisons Russian government agents have used on their lethal missions.

  • Low-cost arsenic sensor could save lives

    Worldwide, 140 million people drink water containing unsafe levels of arsenic, according to the World Health Organization. Short-term exposure causes skin lesions, skin cancer and damage to the cognitive development of children, while long-term exposure leads to fatal internal cancers. A new low-cost, easy-to-use sensor which can test drinking water for arsenic in just one minute.

  • New framework for guiding controversial research still has worrisome gaps

    In December the Department of Health and Human Services (HHS) release lifted the funding moratorium on Gain of Function (GoF) research, following the controversial projects involving H5N1 in 2011. The “Framework for guiding funding decisions about proposed research involving enhanced potential pandemic pathogens” is similar to the January 2017 “P3C0 Framework,” and it came with the bonus of restoring funding for such research – but there are still considerable concerns with how GoF research is evaluated and if these frameworks have really addressed the gaps.

  • New Congressional Biodefense Caucus launched

    A new Congressional Biodefense Caucus was launched last Monday. The caucus said it already has a bipartisan membership roll which includes twenty-seven Members of Congress. The caucus is “dedicated to strengthening our nation’s biodefense enterprise and national security.”
