• Winners Announced in DHS $195K Challenge to Counter Extreme Temperatures

    DHS announced the winners of the Cooling Solutions Challenge prize competition. The winners were each awarded funding, which totaled $195,000, for their innovative and creative ideas that sought climate-friendly cooling solutions to protect people in extreme heat conditions.

  • How Does the U.S. Power Grid Work?

    Responsible for powering the country and its economy, the U.S. energy grid has come under increasing strain due to climate change, and the threat of cyberattacks looms. The U.S. electric grid brings power to millions of homes and businesses via a vast network of transmission and distribution lines. Experts say the grid is increasingly vulnerable to extreme weather events, such as the February 2021 Texas winter storms, and cyberattacks. President Biden has proposed overhauling the grid, but his plans could face legal and political hurdles.

  • Researchers Simulate Defense of the Earth

    Sixty-six million years ago, a giant asteroid impact on the Earth likely caused the extinction of the dinosaurs. Currently no known asteroid poses an immediate threat. But if one day a large asteroid were to be discovered on a collision course with Earth, it might have to be deflected from its trajectory to prevent catastrophic consequences.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • Developing Novel Hybrid Reef-Mimicking Structures

    Despite previous efforts to implement storm mitigation solutions — including concrete breakwaters — damage due to storm surge and flooding continues to devastate coastal areas around the world. In response to these threats, DARPA has launched the Reefense program to develop self-healing, hybrid biological, and engineered reef-mimicking structures to protect civilian and DoD infrastructure, personnel by mitigating damage related to coastal flooding, erosion and storm surge.

  • Preparing National Security Officials for the Challenges of AI

    Artificial intelligence (AI) is one of several rapidly emerging technologies that promise to disrupt not only multiple sectors of the U.S. economy but also the manner in which the U.S. government carries out its foundational responsibility to protect national security consistent with the rule of law and constitutional values. Steve Bunnell writes that “The United States’ national security apparatus is not known for nimbleness, nor is the law that governs it. When it comes to AI, the risk is not just that our generals will fight tomorrow’s war with yesterday’s strategy but also that the United States will lack the legal and policy guardrails that are essential to a lawful, accountable, and ethical protection of the nation’s security.”

  • Taking Steps Toward a Secure Quantum Internet

    Scientists with at the University of Chicago have, for the first time, connected the city of Chicago and suburban labs with a quantum network—nearly doubling the length of what was already one of the longest in the country.

  • The Military Cannot Rely on AI for Strategy or Judgment

    Using artificial intelligence (AI) for warfare has been the promise of science fiction and politicians for years, but new research argues only so much can be automated and shows the value of human judgment.
