• Concerns About Google AI Being Sentient

    From virtual assistants like Apple’s Siri and Amazon’s Alexa, to robotic vacuums and self-driving cars, to automated investment portfolio managers and marketing bots, artificial intelligence has become a big part of our everyday lives. No one knows when humans will create an intelligent or sentient AI, but recent revelations about LaMDA, Google’s artificially intelligent chatbot generator, raised concerns.

  • China’s Disinformation Campaign Against Rare Earth Processing Facilities

    China dominates the production and processing of rare-earth elements (REEs). In order to lessen this dependence on the critical minerals, the U.S. government has been supporting the development of U.S. REE sources. China has been trying to prevent this shift by launching a disinformation campaign: China’ intelligence services have created social media accounts of fake local environmentalists who spread disinformation to local communities about the REE facilities being built nearby.

  • Separation and Purification of Rare-Earth Elements by Microorganisms

    Using naturally occurring and engineered proteins and bacteria, scientists will separate and purify rare-earth elements so they can be used in the defense sector.

  • June Heat Waves Break Records Across the Globe

    It’s not your imagination: This summer is already hotter than normal, from the Russian Arctic to the muggy Gulf Coast. With July and August — usually the hottest summer months — still to come, the early extreme heat offers a grim picture of summer’s growing danger.

  • The Department of the Navy Hosts Climate Tabletop Exercise

    The Department of the Navy hosted a first-of-its-kind Climate Tabletop Exercise to examine the impacts that climate change has on mission, readiness, and warfighting capacity.

  • Technology Can Detect Fake News in Videos

    Social media represent a major channel for the spreading of fake news and disinformation. This situation has been made worse with recent advances in photo and video editing and artificial intelligence tools, which make it easy to tamper with audiovisual files, for example with so-called deepfakes, which combine and superimpose images, audio and video clips to create montages that look like real footage.

  • Soon: Fire-Safe, Recyclable Lithium-Metal Batteries

    To power our increasingly electrified society, energy storage technology must evolve and adapt to meet the growing demand. Lithium-ion batteries, already essential to myriad technology, will require dramatic improvements in high-energy density, safety, temperature resilience, and environmental sustainability in order to provide the type of emission-free future that so many envision. Such improvements are here.

  • The Strategic Relevance of Cybersecurity Skills

    Evidence suggests there is a global cybersecurity skills shortage affecting businesses and governments alike, which means that organizations are struggling to fill their cybersecurity vacancies. Tommaso De Zan writes that “the absence of cybersecurity experts protecting national critical infrastructures constitutes a national security threat, a loophole that may be exploited by malicious actors.”

  • Remote Screening Demonstration at Cape Cod Gateway Airport

    DHS S&T successfully conducted a demonstration of remote screening infrastructure for airport security checkpoints. The Integrated Defense & Security Solutions (IDSS) can send computed tomography (CT) X-ray images of carry-on baggage flagged for threats to remote locations for near real-time analysis.

  • The Administration’s New Vision for the National Flood Insurance Program

    The Biden administration is proposing a major overhaul to the National Flood Insurance Program, or NFIP — the main source of insurance for homeowners who are required to or choose to obtain coverage for flooding. The administration’s flood insurance reforms could improve transparency — and make some Americans more vulnerable.

  • 3D X-Ray Makes it Easier to Detect Hidden Explosive Weapons

    As travelers pass through border crossings, ports of call, airport checkpoints, and various precautionary measures in both federal and private venues, their safety and wellbeing are constantly ensured through various forms of screening technologies that have one critical goal: to identify and alert the proper authorities to potential threats. These technologies do their jobs very effectively, but it is important to ask the question: Can they be improved?

  • A Simple Tool Curbs Hacking, Makes Websites More Secure

    Researchers have developed a scanning tool to make websites less vulnerable to hacking and cyberattacks. The black box security assessment prototype is more effective than existing web scanners which collectively fail to detect the top 10 weaknesses in web applications.

  • Breath Biometrics: Sniffing Out Your Identity

    Biometric authentication like fingerprint and iris scans are a staple of any spy movie, and trying to circumvent those security measures is often a core plot point. Now, researchers have developed a new potential odorous option for the biometric security toolkit: your breath.

  • Assessing the Environmental Impact of Nuclear Power Generation

    Nuclear power is considered a panacea for the environmental degradation caused by fossil fuels. However, its environmental impact and natural resource use need to be assessed. Researchers make a life cycle assessment of resource use in nuclear power generation from uranium.

  • Climate Changes Lead to Water Imbalance, Conflict in Tibetan Plateau

    Climate change is putting an enormous strain on global water resources, and according to researchers, the Tibetan Plateau is suffering from a water imbalance so extreme that it could lead to an increase in international conflicts.
