• The Iran Threat Geiger Counter: Moving Toward Extreme Danger

    The Iran Threat Geiger Counter from the Institute for Science and International Security measures on a regular basis Iran’s hostile intentions toward the United States and U.S. allies, and its capability to turn these hostile intentions into action. As with the radiation levels measured by a Geiger counter, any level above zero represents a degree of danger, and over the last six months, the threat posed by Iran has increased. As of May 2023, the Institute assigns Iran a total threat score of 140 out of 180, up from 130 in October 2022, and assessed as High Danger.

  • Exploring Feasibility of Using Drones to Survey Sites for Low Levels of Radiation

    Drones are tools for search and rescue, traffic monitoring, weather monitoring, and perhaps even package hauling. One day, they may work with humans to augment the task of conducting surveys to detect low levels of radiation—information that could contribute to the decommissioning of sites no longer needed for nuclear-related energy production or research.

  • We Could Easily Make Risky Virological Research Safer

    Lab Accidents happen, and they aren’t especially rare. A new book — appropriately titled Pandora’s Gamble — offers a shocking accounting of the problem, identifying more than a thousand accidents reported to federal regulators from 2008 to 2012. David Wallace-Wells, referring to the recommendations from the National Science Advisory Board for Biosecurity on how to minimize the risks from research biolabs, writes: “These suggestions would not eliminate the risk of lab accidents, but they would reduce the risk — and fairly simply.”

  • Improving Capabilities of Portable Drug Detection Systems

    DHS S&T and partners are working to improve their ability to identify different narcotics, like fentanyl. Narcotics detection systems libraries will be enhanced via the collection of data on approximately 50 restricted substances, primarily related to synthetic opioids like fentanyl, that are scheduled and controlled by the Drug Enforcement Administration.

  • Nuclear Agency Cannot Continue With “Business as Usual” in the Shifting Supercomputing Landscape: Report

    The National Nuclear Security Administration (NNSA) needs to fundamentally rethink the strategy for its next generation of high-performance computing, says a new report from the National Academies of Sciences.

  • Producing Medical Isotopes While Lowering the Risk of Nuclear Weapons Proliferation

    Scientists and engineers at Argonne have been working for decades to help medical isotope production facilities around the world change from the use of highly enriched uranium (HEU) to the use of low-enriched uranium (LEU), which is much more difficult to use in a weapon.

  • Enhancing Advanced Nuclear Reactor Analysis

    Nuclear power is a significant source of steady carbon-neutral electricity, and advanced reactors can add more of it to the U.S. grid, which is vital for the environment and economy. Sandia Lab researchers have developed a standardized screening method to determine the most important radioactive isotopes that could leave an advanced reactor site in the unlikely event of an accident.

  • Creating a Tsunami Early Warning System Using Artificial Intelligence

    Tsunamis are incredibly destructive waves that can destroy coastal infrastructure and cause loss of life. Early warnings for such natural disasters are difficult because the risk of a tsunami is highly dependent on the features of the underwater earthquake that triggers it.

  • Germany: Seeking Solution for Remaining Nuclear Waste

    Nuclear energy in Germany has been history since mid-April. The last three nuclear power plants ended their operations on April 15. Germany’s nuclear power might be gone, but nuclear waste isn’t going anywhere. The search for a location for a final repository remains a challenge.

  • Poisons Are a Potent Tool for Murder in Fiction – a Toxicologist Explains How Some Dangerous Chemicals Kill

    People have used poisons throughout history for a variety of purposes: to hunt animals for food, to treat diseases and to achieve nefarious ends like murder and assassination. But what is a poison? Do all poisons act in the same way? Does the amount of the poison matter in terms of its toxicity?

  • Using GSI Sensor Technology to Prediction Earthquakes

    Can nuclear physics improve the prediction of earthquakes? As part of a new project which aims to provide the foundation for a reliable early warning system for earthquakes in Europe, researchers are building a network of sensors measuring radon levels and other parameters in selected water sources in Europe might be able to detect earthquakes several days in advance.

  • Who Was the Cold War “Umbrella Assassin?”

    A new Danish documentary sheds some light on the shadowy figure of Francesco Gullino, alias “Agent Piccadilly,” the prime suspect in the 1978 murder of Bulgarian dissident Georgi Markov in London.

  • In a Growing Petrochemical Hub, the East Palestine Derailment Triggers “an Uneasy Feeling”

    The Upper Ohio River Valley has been layered in industrial pollution for centuries, and residents are fed up.

  • North Korea’s Nuclear Tests Expose Neighbors to Radiation Risks

    Tens of thousands of North Koreans and people in South Korea, Japan, and China could be exposed to radioactive materials spread through groundwater from an underground nuclear test site. North Korea secretly conducted six tests of nuclear weapons at the Punggye-ri site in the mountainous North Hamgyong Province between 2006 and 2017.

  • Iran Enriching Uranium to Near-Weapon-Grade 84%: IAEA

    IAEA inspectors found uranium particles enriched up to nearly 84 percent in Iran’s underground Fordow uranium enrichment site. The 83.7 percent enriched uranium is just below the 90 percent purity needed for nuclear weapons. Experts say that Iran would need no more than 10-14 days to use the material to produce an atomic bomb.
