• 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.

  • What Are the Risks at the Chernobyl Nuclear Plant?

    Threat of a nuclear catastrophe is low. But experts fear for safety of workers who have been unable to rotate off shift. Communications with the site are down and electricity has reportedly been lost.

  • Russian Attack on, Takeover of Ukraine Plant Ramps Up Nuclear Threat

    Russia’s attack last Friday on a nuclear power plant in southeastern Ukraine has heightened concerns of a nuclear catastrophe in the region, and not only as a result of unintended leaks or possible future attacks on Ukraine’s three remaining nuclear plants. Statements by Russian President Vladimir Putin and Foreign Minister Sergey Lavrov have further deepened worries that Russia may seek to turn material in captured reactors into “dirty bombs.”

  • The Dangers Following Russia’s Attack on the Zaporizhzhia Nuclear Power Plant

    Following recent news of Russian shelling of Zaporizhzhia nuclear power plant in southern Ukraine, which is the largest in Europe, there is great concern over the potential for a Chernobyl-esque release of radioactive material. Several security personnel at the plant were injured by the attack.

  • Exploring the Impact of the COVID-19 Pandemic on Nuclear Security

    A new study examines measures put in place in the nuclear sector in the U.K. to mitigate risks from the pandemic. The study identifies a series of lessons learnt in maintaining nuclear security. It also provides recommendations for managing the continuing impact of the pandemic and preparing for future crises.

  • Improved Nuclear Accident Code Helps Policymakers Assess Risks from Small Reactors

    New software will help the global nuclear industry in assessing the consequences of nuclear accidents. The Maccs code, developed by Sandia researchers, can also evaluate the potential health and environmental risks posed by advanced nuclear reactors and small modular nuclear reactors.

  • Providing Student Research Opportunities to Strengthen Nuclear Security

    Student researchers at The University of Texas at El Paso Aerospace Center will engage in nuclear materials technology research through a five-year, $5 million grant from the U.S. Department of Energy (DOE). Work will focus on the design, synthesis and fabrication of advanced materials.

  • State Department’s New Chemical Forensics International Technical Working Group

    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.

  • Fog Detection Software Helps Keep Travelers Safe

    Fog and low stratus clouds over airports can create dangerous travel conditions that result in costly delays and disrupted travel plans. A new fog detection software will help.

  • The Resilience and Safety of Nuclear Power in the Face of Extreme Events

    As the prospect of extreme global events grows — from natural disasters and intensifying climate change-driven weather patterns that could affect a nuclear plant, to a rise in infectious diseases that could affect its workforce — nuclear power plants’ adaptable workforces and robust designs will be essential to staying resilient and contributing to a low carbon path to the future.

  • Opening Architecture to Make Air Travel Safer, Easier

    Researchers have developed an open architecture for airport screening systems, which will allow air travelers to experience faster and safer security checkpoints — no need to open bags or remove liquids or shoes.
