• To Check Iran’s Missiles, JCPOA Re-Entry is a Must

    Iran’s missile program is a cause for international concern. John Krzyzaniak and Akshai Vikram write that Iran’s increasing willingness and ability to launch missiles at neighboring countries merits a coordinated, international response. If Iran were to ever acquire a nuclear weapon, its unchecked missile program could allow it to hold entire cities at risk in the Middle East and potentially beyond. “If the United States is ever going to restrict Iran’s missile program through diplomacy, re-entering the 2015 Iran nuclear deal is the best – and likely only – way to make it happen,” they write.

  • Comparing Geologic Repository Assessment Tools

    A computer modeling system is designed to answer critical safety assessment questions about future disposal options for spent nuclear fuel deep underground and the system of tunnels, containers and possible concrete-like barriers used to keep the radioactive material contained far from the surface and water sources.

  • Artificial 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.”

  • Risks of an Unfamiliar New Nuclear Age

    High-tech advances in weapons technologies and a return of ‘great power nuclear politics’, risk the world ‘sleepwalking’ into a nuclear age vastly different from the established order of the Cold War, experts warn. Stockpiles are much reduced from the peak of up to 70,000 nuclear weapons seen in the 1980s, but progress in a number of new or ‘disruptive’ technologies threatens to fundamentally change the central pillars on which nuclear order, stability and risk reduction are based.

  • New Treatment Removes Radioactive Barium from Nuclear Wastewater

    Exposure to ionizing radiation can be extremely dangerous for humans and animals. High acute doses lead to radiation burns and radiation sickness that can be lethal. Researchers havedeveloped a new process that offers a rapid and effective path to remove some of the most harmful of these ions – barium.

  • Risks of a Dirty Bomb Attack Are Increasing

    In a new factsheet, the GAO says that the risks of a dirty bomb attack are increasing and the consequences could be devastating.

  • New Wildfire Detection System Receives Funding Boost

    The high intensity of the recent fire seasons in Oregon, coupled with the increasing wildfire risk this year as approximately three-quarters of the state is now in severe drought conditions, has highlighted how critical a new project, aiming to help with the early detection and monitoring of wildfires, is — both for firefighters and the general public.

  • Iran Vows to Continue Nuclear Activities

    Iranian President Ebrahim Raisi has said Iran will continue nuclear development activities as talks to revive Tehran’s nuclear deal with world powers remain stalled. The nuclear deal collapsed four years ago when former President Donald Trump withdrew the United States from the agreement, allowing Iran to vastly expanded its nuclear work.

  • DIY Innovations for Bomb Squads

    Bomb-squad members must effectively employ critical thinking and problem-solving skills while working in stressful, potentially life-threatening situations. DHS S&T notes that bomb technicians’ ability to expect the unexpected and adjust accordingly has created a consistent pipeline of do-it-yourself (DIY) inventions to solve everyday issues they face, and the S&T works to validate these innovations.

  • Food Security During a Nuclear Winter

    A nuclear war would cause global blockage of the sun for several years due to injections of black carbon soot into the upper atmosphere, covering most of the planet with black clouds. This could result in less than 40 percent of normal light levels near the equator and less than 5 percent normal light levels near the poles. Research focuses on how meeting food security and nutrition in post-catastrophe conditions, which could last 15 years in some wet tropical forests.

  • Current and Future Challenges to National Biodefense

    The Bipartisan Commission on Biodefense met to discuss the expanding landscape of current and future biological threats, the roles and responsibilities of the federal government in assessing and preparing for various biological threats, and biological weapons, bioterrorism, and biological arms races with the public.

  • Russia’s Remaining Weapons Are Horrific and Confounding

    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.

  • Tracing the Path of Pathogens after Large-Scale Contamination with Biological Agents

    To respond quickly to contamination with a biological agent near a major coastal city, DHS ST and partners have examined the movement of pathogen’ spores, which may be carried downstream by runoff after rainstorms, thereby complicating mitigation and decontamination measures.

  • UN, U.S. Dismiss Russian Claim of Biological Weapons Program in Ukraine

    Western nations criticized Russia on Friday for trying to use the U.N. Security Council to spread disinformation and lies about alleged biological weapons laboratories in Ukraine, which the U.N. said are untrue.

  • Can Ukraine Be Saved Without Triggering a Nuclear Response?

    Worries about the war in Ukraine are deepened by the prospect that if, against the odds, Russian forces are brought to the point of defeat, Putin will launch a ‘battlefield’ or ‘tactical’ nuclear weapon to destroy the forces opposing the Russian military, and, perhaps, even attack military bases inside neighboring countries – some are NATO member states – which provide supplies to the resistance.
