• Keeping Communities Safe from Chemical Hazards During Hurricane Season

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

  • The Pandemic: Implications for Terrorist Interest in Biological Weapons

    What if the IS or al-Qaeda obtained and spread a highly contagious virus in a community or country that they sought to punish? With the pandemic highlighting weaknesses in response efforts, will these groups now seek to obtain infectious viruses to achieve these same deadly results?

  • Bolstering Security by Detecting Hidden Anomalies

    The ability to assess deviations from expected movement requires a deep characterization of normal activity across times of day, days of the week, weeks of the year as well as across different types of people. Current human mobility modeling techniques can provide high-level insight into human movement for the study of disease spread or population migration, but they don’t provide the complex, fine-grained modeling the Intelligence Community (IC) needs to identify more subtle anomalies with confidence.

  • Threshold Reached: Iranian Nuclear Breakout Timeline Now at Zero

    Iran has crossed a new, dangerous threshold: Iran’s breakout time is now at zero. It has enough 60 percent enriched uranium, or highly enriched uranium (HEU), to be assured it could fashion a nuclear explosive. If Iran wanted to further enrich its 60 percent HEU up to weapon-grade HEU, or 90 percent, it could do so within a few weeks with only a few of its advanced centrifuge cascades.

  • Iran’s Current Nuclear-Weapons Status: The Facts

    A report published in April by the Institute for Science and International Security, and an interview with David Albright, the report’s co-author, offer startling, and disturbing, insights into the rapid, and likely irreversible, progress Iran has made toward developing a workable nuclear weapon since the Trump administration, in 2018, decided to withdraw from the 2015 nuclear deal.

  • Keeping Communities Safe from Chemical Hazards During Hurricane

    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.

  • Iran Now Has Enough Fissile Material for One Nuclear Bomb: IAEA

    Iran has enriched enough uranium for making one Hiroshima-size nuclear bomb, the International Atomic Energy Agency (IAEA) said in its quarterly report. The IAEA says that Iran now has around 43 kilograms (95 pounds) of uranium enriched to 60 percent (in March, Iran had 33 kilograms of uranium enriched to 60 percent). The 43 kg of 60 percent enriched uranium would yield about 22-25 kg of uranium enriched to 90 percent, which is weapon-grade.

  • Reforming DHS’s Biodefense Operations and Governance

    Today’s biological threats show no signs of desisting any time soon. Naturally occurring outbreaks, epidemics and pandemics, and laboratory accidents pose a growing challenge – while the number of high-containment laboratories and amount of dangerous research continues to increase unabated. “DHS, as chief among those federal departments and agencies responsible for securing the homeland, must overcome its current state of fractionation and demonstrate to the rest of the government, country, and world that it is capable of coordinating and leading efforts in biodefense and other arenas,” Carrie Cordero and Asha M. George write.

  • Codifying Support for Nuclear Inspections in Iran

    The main obstacle for a new nuclear deal with Iran is Iran’s disregard of its safeguards commitments and defiance of standard International Atomic Energy Agency (IAEA) procedures are more problematic for a nuclear deal. Resolving those outstanding inspection issues offers a far more promising pathway to prevent Iran from building nuclear weapons in the long run.

  • Computer Code to Speed Up Airport Security

    Imagine moving through airport security without having to take off your shoes or belt or getting pulled aside. Researchers are working on the Open Threat Assessment Platform, which allows the Transportation Security Administration to respond more quickly and easily to threats to air travel safety.

  • The Future of Nuclear Waste: What’s the Plan and Can It Be Safe?

    The UK is planning to significantly expand its nuclear capability — from approximately 8 gigawatts (GW) today to 24GW by 2050, which would meet around 25% of the forecast UK energy demand — in an effort to decrease its reliance on carbon-based fossil fuels. New reactors will inevitably mean more radioactive waste. Above-ground nuclear waste storage isn’t a feasible long term plan. What are the alternatives?

  • Russia's Claims of Ukrainian Biological Weapons: A Propaganda Ploy?

    Since its invasion of Ukraine, Russia has claimed Kyiv is developing biological weapons with support from the US and Germany. Experts familiar with laboratories in Ukraine say the accusations are groundless.

  • 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.”
