• Helping Keep Communities Safe from Chemical Hazards During Severe Weather

    The destruction wrought by extreme weather is often spectacular in its devastation, but the quiet threat of subsequent chemical release can be just as deadly. Damage to infrastructure can lead to toxic substances like chlorine or ammonia contaminating our air and water.

  • Quick Detection of Uranium Isotopes Helps Safeguard Nuclear Materials

    Researchers have developed a rapid way to measure isotopic ratios of uranium and plutonium collected on environmental swipes, which could help International Atomic Energy Agency analysts detect the presence of undeclared nuclear activities or material.

  • ShakeOut 2021: Earthquake Awareness Helps Community Preparedness

    Nearly half of Americans are exposed to potentially damaging earthquakes where they work and live. Still others will be at risk when traveling. It’s a good idea for everyone, everywhere to know how to protect themselves during an earthquake.

  • New Treatment Technology Could Reduce Nuclear Waste Burden

    Researchers have developed a novel treatment technology that may help to significantly reduce the burden of nuclear waste. This breakthrough could therefore significantly speed up disposal of such material and reduce the overall cost of dealing with our legacy waste.

  • Earthquake System Model with Better Detection Capabilities

    researchers developed a machine learning model that improves the accuracy of detecting earthquakes by 14.5 percent compared to the most accurate current existing model.

  • New, $125 Million Project Aims to Detect Emerging Viruses

    A new project, funded with $125 million from USAID, aims to detect and characterize unknown viruses which have the potential to spill over from wildlife and domestic animals to human populations. The 5-year project is expected to yield 8,000 to 12,000 novel viruses, which researchers will then screen and sequence the genomes of the ones that pose the most risk to animal and human health.

  • The Sound and the Fury: Inside the Mystery of the Havana Embassy

    More than a year after American diplomats began to suffer strange, concussion-like symptoms in Cuba, a U.S. investigation is no closer to determining how they were hurt or by whom, and the FBI and CIA are at odds over the case. A ProPublica investigation reveals the many layers to the mystery — and the political maneuvering that is reshaping U.S.-Cuba relations.

  • How Big Was the 2020 Beirut Explosion?

    On 4 August 2020, one of the largest non-nuclear explosions in history pulverized a Beirut port and damaged more than half the city. The explosion resulted from the detonation of tons of ammonium nitrate, a combustible chemical compound. The explosive yield estimates varied widely, and in some cases, were inconsistent with what would be expected based on the amount of ammonium nitrate stored at the Beirut harbor.

  • Bolstering Speed, Flexibility of Response to Nuclear Events

    Researchers are combining basic research and development of emergent technologies, predictive capabilities, and systems assessment to revolutionize the speed and flexibility of technical nuclear forensic (TNF) response to nuclear events.

  • Anthrax Attacks: 20 Years On

    Twenty years ago this month the United States experienced the scary anthrax letter attacks, which targeted major media outlets and members of Congress.

  • As the West Watches, Iran Enriches Uranium

    Iran may now be capable of producing enough weapons-grade uranium for a single nuclear warhead within just a month. While Iran continues to make progress enriching uranium, nuclear diplomacy seems to be stalled.

  • Redesigning Radiation Monitors at U.S. Ports of Entry

    Every day at ports of entry around the country, hundreds of thousands of vehicles and containers cross into the country. Since 9/11, all incoming vehicles and containers at land crossings, rail crossings, mail facilities, and shipping terminals are scanned by Customs and Border Protection (CBP) officers to detect potential threats, including radiation. The time has come to replace and upgrade the aging radiation detection systems.

  • IAEA Monitors Allowed to Service Cameras at Sensitive Nuclear Sites

    An agreement has been reached between Iran and the IAEA to allow international inspectors to service surveillance cameras at Iran’s sensitive nuclear sites and to continue filming there. The agreement, announced Sunday, averts a diplomatic showdown this week.

  • Apollo Program-Style Pandemic Preparedness Plan

    Last week, the Biden administration announced a new biosecurity plan which it likened to the Apollo program of the late 1960s. This $65 billion proposal would be one of the largest investments in public health in American history and would “remake the nation’s pandemic preparedness infrastructure in the wake of Covid-19.”

  • Keeping First Responders Safe by Detecting Cyanide Poisoning after Fires

    When first responders rush to a burning building to subdue the fire and save lives, it is not just the flames that are dangerous and potentially lethal, but also toxic fumes like cyanide that are released when certain materials are incinerated. These fumes, mixed with smoke, are so toxic that even in very low quantities may pose more risk than the fire itself. Chemists at DHS S&T have invented a test to indicate possible toxic cyanide exposure at the fire scene.
