• Havana Syndrome Not Caused by Directed-Energy Weapons: U.S. Intelligence

    In 2016 in Havana, Cuba’s capital, a growing number of U.S. diplomats reported symptoms of unexplained ailment, and over the next five years, employees in many other U.S. embassies complained about identical symptoms, which included dizziness, nausea, headaches, ringing ears, and disorientation. A comprehensive investigation by several agencies of the U.S. intelligence community has now concluded that the symptoms of what came to be called the Havana Syndrome were not the result of an adversary nation using directed-energy or radiation weapons.

  • AI Nuclear Weapons Catastrophe Can Be Avoided

    There is a growing concern that emerging AI features will only increase the potential for disaster through the possibility of semiautonomous or fully autonomous nuclear weapons. Noah Greene writes that “As the Soviet-era Col. Petrov case kindly taught us, without a human firmly in control of the nuclear command-and-control structure, the odds of disaster creep slowly toward an unintended or uncontrolled nuclear exchange.”

  • Great Leap Nowhere: The Challenges of China’s Semiconductor Industry

    China is struggling in the battle for advanced semiconductor technology. With President Joe Biden’s most recent round of export controls on semiconductors, China is now facing an increasingly urgent challenge as it seeks to ramp up its domestic innovative capacity for high-end chips. These difficulties and challenges notwithstanding, Elliot Ji writes, “U.S. policymakers should be keenly aware that China’s relative success with creative adaptation means that it can boost certain sectors of the chip industry by exploiting leaky export controls and engaging in cyber espionage.”

  • Digital Twins Could Protect Manufacturers from Cyberattacks

    Detailed virtual copies of physical objects, called digital twins, hold the promise of better products across automotive, health care, aerospace and other industries. According to a new study, cybersecurity may also fit neatly into the digital twin portfolio.

  • Can a Cyber shuffle Stop Hackers from Taking Over a Military Aircraft?

    A cybersecurity technique that shuffles network addresses like a blackjack dealer shuffles playing cards could effectively befuddle hackers to take control of a military jet, commercial airliner or spacecraft. Sandia, Purdue team up to test cyberdefense against an algorithm trained to break it.

  • Artificial Intelligence Reframes Nuclear Material Studies

    The future of nuclear energy, which can produce electricity without harmful emissions, depends on discovery of new materials. A scientist at Argonne is using computer vision to separate the best candidates from a crowded field.

  • Chip War: The Fight for the World’s Most Critical Technology

    Forget the “Malacca dilemma,” that is, how China protects the narrow strait linking the Indian and Pacific oceans, which is the conduit for around 60% of China’s oil imports. These days, Chris Miller writes in his new book, China’s leaders are more concerned about a blockade “measured in bytes rather than barrels.”

  • Improving the Speed and Safety of Airport Security Screening

    For decades, airports around the nation have employed sensitive canine noses to detect concealed explosives. While this four-legged fleet has been effective and efficient, researchers have yet to build a mechanical method that can mimic their abilities. Researchers seek ways to build non-contact screening methods that can detect concealed explosives at airports.

  • How One of the World's Most Popular Open-Source Security Monitoring Platforms Was Developed

    A tool from the internet’s early days keeps Microsoft’s users secure while supporting the open-source paradigm.

  • 2023 Border Security & Intelligence Summit

    Defense Strategies Institute announced its 11th Annual Border Security & Intelligence Summit. This forum will bring together DHS, IC, Federal Agencies, and Industry to discuss the protection of U.S borders through enhanced technology and intelligence solutions.

  • The Most Advanced Bay Area Earthquake Simulations to Be Publicly Available

    Accurately modeling the effects of an earthquake is possible, but it requires intricate physics-based models that can only be run on advanced supercomputers. The data from such models are invaluable for the earthquake research community and engineers seeking to build and retrofit earthquake-resilient homes, businesses, and infrastructure. Supercomputer-generated simulations will soon be accessible on an open-access website.

  • Can Space Dust Slow Global Warming?

    Scientists believe dust launched from the moon could reduce solar radiation enough to lessen the impact of climate change.

  • Breakthrough Alert Messaging for a Mobile Public

    It is in the Wildland Urban Interface (WUI) that the danger and damage from the growing risk of wildfires is most prevalent. Of paramount importance is alerting people in the path of fires and enabling their safe evacuation from the area.

  • NIST Selects ‘Lightweight Cryptography’ Algorithms to Protect Small Devices

    The algorithms are designed to protect data created and transmitted by the Internet of Things and other small electronics.

  • Looking for Critical Minerals in Mine Waste

    Mine waste is the material left over after mining. It consists of tailings, the material that remains after mined ore is milled and concentrated, as well as the topsoil, waste rock and other materials that were removed to get to the ore. Some critical-mineral commodities, like rare earth elements, are known to occur alongside more commonly mined minerals like iron or nickel. Because of this, mine-waste sites are now being revisited.
