• CHEMICAL WARFAREA Protein Could Prevent Chemical Warfare Attack

    A team of scientists has designed a synthetic protein that quickly detects molecules of a deadly nerve agent that has been classified by the United Nations as a weapon of mass destruction and could be used in a chemical warfare attack.

    Extreme weather from hurricanes and tropical storms can devastate communities along the Atlantic, Gulf and Pacific coasts, and the threat of subsequent hazard chemical releases can be just as deadly.

  • ARGUMENT: AI & WMDsArtificial Intelligence and Chemical and Biological Weapons

    A recent article in Nature offers a disturbing look at the use of artificial intelligence (AI) in the creation of chemical and biological weapons. “Anyone unfamiliar with recent innovations in the use of AI to model new drugs will be unpleasantly surprised,” Paul Rosenzweig writes. “The benefits of these innovations are clear. Unfortunately, the possibilities for malicious uses are also becoming clear.”

  • UKRAINE WARRussia’s Remaining Weapons Are Horrific and Confounding

    By Christina Pazzanese

    Along with concerns over the possible deployment of tactical nuclear weapons, the Biden administration is now warning that the Russian military may launch a chemical weapons attack in Ukraine. Harvard Kennedy School’s Matthew Bunn assesses threat, possible fallout of chemical attack in Ukraine, including the excruciating choices Biden and NATO would face.

    The U.S. Department of State has established the Chemical Forensics International Technical Working Group (CFITWG) to address gaps in chemical forensic science and capabilities through an international partnership of experts from science, policy, academic, law enforcement, and export-control organizations.

  • Chemical HazardsHelping Keep Communities Safe from Chemical Hazards During Severe Weather

    The destruction wrought by extreme weather is often spectacular in its devastation, but the quiet threat of subsequent chemical release can be just as deadly. Damage to infrastructure can lead to toxic substances like chlorine or ammonia contaminating our air and water.

  • Cyanide detectionKeeping First Responders Safe by Detecting Cyanide Poisoning after Fires

    When first responders rush to a burning building to subdue the fire and save lives, it is not just the flames that are dangerous and potentially lethal, but also toxic fumes like cyanide that are released when certain materials are incinerated. These fumes, mixed with smoke, are so toxic that even in very low quantities may pose more risk than the fire itself. Chemists at DHS S&T have invented a test to indicate possible toxic cyanide exposure at the fire scene.

  • Transporting AmmoniaSecuring Transportation of Ammonia

    Ammonia is used in many cleaning products, and it also fertilizes most of the U.S. agricultural crops. It will soon be used as emission free green fuel to power ships. With all of the many benefits, there are risks as well, as ammonia is the most produced and widely distributed toxic inhalation hazard chemical in the United States. If released in large quantities, it poses a significant risk to life and the health of those exposed.

  • BiosensorsNew Biosensor Detect Toxins and More

    A new device is not quite the Star Trek “tricorder” medical scanner, but it’s a step in the right direction. The Portable EnGineered Analytic Sensor with aUtomated Sampling (PEGASUS) is a miniaturized waveguide-based optical sensor that can detect toxins, bacterial signatures, viral signatures, biothreats, white powders and more, from samples such as blood, water, CSF, food, and animal samples.

  • Chemical weaponsUN Watchdog Confirms Assad Used Chemical Weapons against Civilians

    The Organization for the Prohibition of Chemical Weapons (OPCW) on Monday released the findings of the second report by the OPCW Investigation and Identification Team (IIT). IIT concludes that units of the Syrian Arab Air Force used chemical weapons in Saraqib on 4 February 2018.Since 2011, the year the civil war in Syria began, the Assad regime has launched atleast 336 chemical attacks, using Sarin and chlorine, against Sunni civilians.

  • BOOKSHELF : Nerve agentsToxic: A History of Nerve Agents, from Nazi Germany to Putin’s Russia

    By Chris Quillen

    Nerve agents are very much in the news these days. Bashar al-Assad’s government in Syria repeatedly used Sarin against its own people during that country’s civil war. The Putin regime employed Novichoks in both Russia and the United Kingdom against citizens it deemed insufficiently loyal to Moscow. North Korea’s Kim Jong Un utilized VX in the assassination of his brother at an airport in Kuala Lumpur, Malaysia. Across the globe, the use of nerve agents is challenging the international nonproliferation regime in numerous ways.

  • DetectionInnovative Chemical Weapons Detection Technology

    An innovative new chemical detection technology called SEDONA, or SpEctroscopic Detection of Nerve Agents, was recognized as a 2020 R&D 100 Award-winner.When deployed at security checkpoints, border crossings, and ports of entry across the country, SEDONA will enhance DHS’s abilities to detect and intercept dangerous chemicals and nerve agents.
