• IRAN’S NUKESIran's Nuclear Activities 'Raises Eyebrows' at IAEA

    By Biresh Banerjee and Zachary Crellin

    Iran’s enrichment of uranium and a lack of access to international monitors is fueling suspicions about its nuclear activities. The International Atomic Energy Agency said its committed to promoting dialogue with Tehran.

  • RADIATION DETECTIONA New Way to Detect Radiation Involving Cheap Ceramics

    By Elizabeth A. Thomson

    The radiation detectors used today for applications like inspecting cargo ships for smuggled nuclear materials are expensive and cannot operate in harsh environments, among other disadvantages. Work by MIT engineers could lead to plethora of new applications, including better detectors for nuclear materials at ports.

  • IRAN’S THREATMemo: The Reported Destruction of Secret Workshop in 2020

    By David Albright, Sarah Burkhard, Spencer Faragasso, and Mohammadreza Giveh

    On March 24, 2024, Iran International reported that an “industrial production workshop […] belonging to the Atomic Energy Organization of Iran (AEOI) was deliberately set on fire” in the summer of 2020. 1 The incident was not reported publicly at the time, and Iran International cites judicial and intelligence documents provided by a hacking group as their source. Iran alleged that the Israeli intelligence service, Mossad, hired a group of nine Iranians to destroy the facility.

  • BIOSECURITYCanada’s Biosecurity Scandal: The Risks of Foreign Interference in Life Sciences

    By Brendan Walker-Munro

    In July 2019, world-renowned biological researchers Xiangguo Qiu and Keding Cheng were quietly walked out of the Canadian government’s National Microbiology Lab (NML). The original allegation against them was that Qiu had authorized a shipment to China of some of the deadliest viruses on the planet, including Ebola and Nipah. Then the story seemed to go away—until now.

  • PROTECTING CRITICAL INFRASTRUCTUREPlan B: Keeping Nuclear Power Plants Cool in a Warmer, Drier Climate

    By Kristen Mally Dean

    Waterways — tried and true cooling sources for nuclear power plants — could get warmer due to global climate change. Climate scientists and nuclear science and engineering experts are joining forces to develop a plan B for nuclear power.

  • AIRPORT SECURITYPrototype Self-Service Screening System Unveiled

    TSA and DHS S&T unveiled a prototype checkpoint technology, the self-service screening system, at Harry Reid International Airport (LAS) in Las Vegas, NV. The aim is to provide a near self-sufficient passenger screening process while enabling passengers to directly receive on-person alarm information and allow for the passenger self-resolution of those alarms.

  • NUCLEAR RISKSRaging Texas Wildfires Force U.S. Main Nuclear Weapon Facility to Evacuate, Temporarily Shut Down

    Raging wildfires in the Texas panhandle have forced the evacuation and temporary closure of the Pantex plant, the U.S. premier nuclear weapons assembly facility. The Pantex plant said that “All weapons and special materials are safe and unaffected.”

  • NUCLEAR RISKSDecades After the U.S. Buried Nuclear Waste Abroad, Climate Change Could Unearth It

    By Anita Hofschneider

    A new report says melting ice sheets and rising seas could disturb waste from U.S. nuclear projects in Greenland and the Marshall Islands

  • NUCLEAR TRAFFICKINGJapanese Yakuza Leader Charged with Trafficking Nuclear Materials

    Takeshi Ebisawa of Japan, leader within the Yakuza transnational organized crime syndicate, was charged with trafficking nuclear materials, including uranium and weapons-grade plutonium.

  • BIORISKSAttributing Biological Weapons Use

    Why is attribution of BW use important? During a biological incident, including BW use, what evidence might provide valuable information to facilitate attribution? What is the state of the science for determining the origin of a biological incident, including BW use? What capabilities does DoD possess or could it develop to facilitate attribution of BW use?

  • NUCLEAR PROLIFERATIONA Non-Proliferation Solution: Using Antineutrinos to Surveil Nuclear Reactors

    Antineutrinos generated in nuclear fission can be measured to remotely monitor the operation of nuclear reactors and verify that they are not being used to produce nuclear weapons, scientists report. Thanks to a newly developed method, it is now possible to estimate a reactor’s operation status, fuel burnup, and fuel composition based entirely on its antineutrino emissions. This technique could contribute massively to nuclear non-proliferation efforts and, in turn, safer nuclear energy.

  • SECURITY SCREENINGSpeedier Security Screening in the Palm of the Hand

    Though pat downs are currently an essential element of keeping travelers safe at the airport, it slows the screening process for people waiting in line and can be an uncomfortable experience for the passenger being screened. Reducing the need for pat downs may soon be easier.

  • IRAN’S NUKESIran Triples Production of Enriched Uranium

    Iran has tripled its production of uranium enriched to 60 percent, after slowing down of production earlier this year, the International Atomic Energy Agency (IAEA) reported on Tuesday. Iran, free of the restrictions it accepted as part of the 2015 deal, is now producing about 9 kg a month of uranium enriched to 60 percent.

  • DETECTIONLeveraging Artificial Intelligence in Explosives, Narcotic Detection

    DHS S&T is applying emerging technologies in the development of artificial intelligence / machine learning technologies – and searching for ways to use these technologies to identify dangerous compounds, like those found in explosives and narcotics.

  • AIRPORT SCREENINGA Self-Service Screening Option Coming to the Airport Near You

    Self-service screening is coming to airport checkpoints, thanks to the Science and Technology Directorate’s Screening at Speed Program. A pilot of a new self-service screening system is scheduled to begin in January at Harry Reid International Airport in Las Vegas, Nevada.
