• Iran Confirms End to Snap Inspections as U.S. Seeks to “Lengthen, Strengthen” Nuclear Deal

    Iranian state television has confirmed that the country has ended its implementation of the Additional Protocol, which allows for so-called snap inspections of nuclear-related sites, signaling the further disintegration of atomic safeguards in place since a 2015 nuclear deal with world powers.

  • IAEA Chief: Iran to Give “Less Access” to UN Nuclear Inspectors

    The head of the UN’s nuclear watchdog agency said after talks in Iran on February 21 over Tehran’s threat to curb international inspections that the two sides reached an agreement but that Iran will suspend a key document on cooperation and offer “less access” to inspectors.

  • Identifying Skin Proteins Left on IEDs

    Following a terrorist bombing, can the bomb maker be identified by skin proteins left on the bomb components they handled? A small team of biology and explosives experts combined their knowledge and experience to successfully carry out a series of 26 confined detonations over a three-day period.

  • Robot Seeks Out Chemical Agents

    Scientists have successfully tested a fully autonomous robot that will help defense and security personnel dealing with hazardous scenes. The development of the robot means that humans and machines can now share the burden of detecting and report dangerous chemicals over large areas.

  • Bold Action Can End Era of Pandemic Threats By 2030

    The Bipartisan Commission on Biodefense has called on the federal government to urgently implement the recommendations specified in its new report, The Apollo Program for Biodefense: Winning the Race Against Biological Threats. The report details an ambitious program to develop and deploy the technologies needed to defend against all biological threats, empower public health, and prevent pandemics.

  • Pandemic Shows Need for Biological Readiness

    President Joe Biden’s inauguration comes during the worst stage of the deadliest biological event of our lifetimes. As bad as this pandemic is, imagine if instead it were caused by the deliberate release of a sophisticated biological weapon. About 2 percent of those infected have died of COVID-19, while a disease such as smallpox kills at a 30 percent rate. A bioengineered pathogen could be even more lethal. Our failed response to the pandemic in 2020 has exposed a gaping vulnerability to biological threats, ranging from natural outbreaks to deliberate biological weapons attacks.

  • Unifying U.S. Atmospheric Biology Research to Prevent Risks to National Security

    Global circulating winds can carry bacteria, fungal spores, viruses and pollen over long distances and across national borders, but the United States is ill-prepared to confront future disease outbreaks or food-supply threats caused by airborne organisms. In the United States, research and monitoring of airborne organisms is split between an array of federal agencies. The lack of coordination and information-sharing can effectively cripple the U.S. response to national security threats, such as pandemics.

  • Iran Vows 20 Percent Uranium Enrichment “As Soon As Possible”

    Iran said on January 2 that it plans to enrich uranium up to 20 percent purity at its underground Fordow nuclear facility “as soon as possible,” a level far above limits set by an international nuclear accord. Iran’s public announcement come a day after the International Atomic Energy Agency (IAEA) said that Tehran had revealed its intention in a letter to the UN nuclear watchdog.

  • Analyzing Forensic Signatures of Nuclear Materials to Prevent Smuggling

    A scientific exercise scenario involved seized nuclear materials for which law enforcement requested nuclear forensic analysis to help discern whether the process histories of the two seized materials were consistent with one another and related to similar materials seized previously by authorities. The exercise was part of an international nuclear forensic drill in support of a simulated nuclear smuggling investigation.

  • Nuclear Waste Storage Canisters to Be Tested

    Three 22.5-ton, 16.5-feet-long stainless-steel storage canisters, with heaters and instrumentation to simulate nuclear waste so researchers can study their durability, will be tested at Sandia National Lab. The three canisters have never contained any nuclear materials. They will be used to study how much salt gathers on canisters over time. Sandia will also study the potential for cracks caused by salt- and stress-induced corrosion with additional canisters that will be delivered during the next stage of the project.

  • K9 Chemistry: A Safer Way to Train Detection Dogs

    Trained dogs are incredible chemical sensors, far better at detecting explosives, narcotics and other substances than even the most advanced technological device. But one challenge is that dogs have to be trained, and training them with real hazardous substances can be inconvenient and dangerous.

  • European Powers "Deeply Worried" By Iran's Uranium Enrichment Plans

    Britain, France, and Germany say Iran’s apparent plan to install additional advanced centrifuges at its main nuclear enrichment facility is “deeply worrying” and contrary to the 2015 nuclear deal with world powers. A confidential report by the UN’s atomic watchdog, the International Atomic Energy Agency (IAEA), said Iran plans to install three more cascades of advanced IR-2m centrifuges in its underground plant at Natanz.

  • Iran Violating 2015 Nuclear Deal Again with Use of Advanced Centrifuges: Reuters

    Reuters obtained a confidential IAEA report which says that Iran plans to install more advanced uranium-enriching centrifuges at an underground plant in breach of its troubled deal with major powers. The confidential IAEA report said Iran plans to install three more clusters of advanced IR-2m centrifuges in the underground plant at Natanz, located about 300 kilometers south of the capital, Tehran.

  • Students of Nuclear Security Have a Problem. Here’s How to Help Them.

    Radioactive materials are attractive targets to thieves and other bad actors. These are rare finds, valuable on the black market and relatively easy to weaponize. New security professionals rarely learn practical skills for protecting these targets until they are on the job at nuclear power plants, research reactors, processing plants and other nuclear facilities.

  • New Information on Syria’s Chemical Weapons Program

    A new report offers the most comprehensive investigative report to date on Syria’s Scientific Studies and Research Centre (SSRC), the entity at the heart of Syria’s chemical weapons program. The report contains new information on how the Syrian government orchestrated attacks using sarin, a banned nerve agent whose use is considered a war crime.
