• How Does Climate Change Drive Migration, and What Can Be Done about It?

    April saw a 20-year high in the number of people stopped at the U.S./Mexico border, and President Joe Biden recently raised the cap on annual refugee admissions. Stanford researchers discuss how climate change’s effect on migration will change, how we can prepare for the impacts and what kind of policies could help alleviate the issue.

  • Climate Change Increases Extreme Rainfall and the Chance of Floods

    Climate experts warn that, without urgent action, climate change will continue to cause an increase in the intensity of extreme rainfall that can lead to severe flooding.

  • Challenges in Implementing Physical Security Measures in K–12 Schools

    A core responsibility of the local education agencies (LEAs) that operate kindergarten-through–12th grade (K–12) schools across the United States is creating safe and secure environments that support effective teaching and learning. What challenges do LEAs face related to school physical security?

  • How AI Could Alert Firefighters of Imminent Danger

    Firefighting is a race against time, but exactly how much time? For firefighters, that part is often unclear. Building fires can turn from bad to deadly in an instant, and the warning signs are frequently difficult to discern amid the mayhem of an inferno. To remove this major blind spot, NIST researchers have developed P-Flash, or the Prediction Model for Flashover.

  • A 20-Foot Sea Wall? Miami Faces the Hard Choices of Climate Change.

    In Miami, the U.S. metropolitan area that is perhaps most exposed to sea-level rise, the problem is not climate change denialism. Patricia Mazzei writes that “the trouble is that the magnitude of the interconnected obstacles the region faces can feel overwhelming, and none of the possible solutions are cheap, easy or pretty.”

  • Retreat from Rising Seas

    As climate change causes seas to rise, coastal communities around the world face a difficult dilemma: Should they fight to keep their homes and communities above water, or accept that moving inland may be the best option?

  • Shadow Figment Technology Foils Cyberattacks

    Scientists have created a cybersecurity technology called Shadow Figment that is designed to lure hackers into an artificial world, then stop them from doing damage by feeding them illusory tidbits of success.

  • Increasing Flood Risks in the U.K.

    As climate change continues to cause unpredictable and extreme weather events around the world, researchers are calling for engineers to rethink how they design for flood prevention. Flood frequency analysis has been the cornerstone of flood risk control, hydraulic structure design, and water resource management, but the researchers say that flood series in most areas do not follow historical patterns.

  • Tipping Elements Can Destabilize Each Other, Leading to Climate Domino Effects

    Under global warming, tipping elements in the Earth system can destabilize each other and eventually lead to climate domino effects. The ice sheets on Greenland and West Antarctica are potential starting points for tipping cascades, a novel network analysis reveals.

  • DOD UFO Report Boldly Goes Where No Official Report Has Gone Before

    If you have an interest in UFOs (unidentified flying objects, for the uninitiated) and have always wondered what exactly the US government and intelligence services know about them, June may be a big month for you, as a DOD task force will share data it collected on unusual flight phenomena with Congress. UFO enthusiasts rejoice, but some experts with decades of research under his belt doesn’t believe aliens have ever been to Earth.

  • Lawmakers Question DOJ Funding of Unproven Predictive Policing Technology

    Lawmakers asked the Justice Department to account for how it funds and oversees so-called predictive policing programs, especially whether the programs actually reduce crime, and the potential to amplify biased results that harm marginalized groups. “We ask DOJ to help ensure that any predictive policing algorithms in use are fully documented, subjected to ongoing, independent audits by experts, and made to provide a system of due process for those impacted,” the lawmakers wrote.

  • Reframing Infrastructure Security

    Infrastructure has always been a target in warfare, says Mikhail Chester, an ASU professor of civil and environmental engineering. “Think about military aircraft dropping bombs on bridges or railroad lines,” he says. Chester points to the recent ransomware attack that shut down one of America’s largest fuel pipeline networks. “This kind of problem is growing, and it can’t be solved through remedial repairs to old infrastructure,” Chester said.

  • Offshore Carbon Capture, Storage

    Carbon capture and storage is the practice of trapping and disposing of carbon dioxide in rock below the seafloor or earth’s surface to reduce buildup of this greenhouse gas in the atmosphere.

  • China’s Determined Effort to Build an S&T Infrastructure

    For half a century, China, with dogged determination, has pursued its effort to build an S&T infrastructure. A new report from the Center for Security and Emerging Technology (CSET) notes that foreign technology acquisition continues to play a large role in this effort, with commercial technology products becoming increasingly attractive targets. Beijing’s “hybrid innovation system” blends forms of academic collaboration, industry partnerships, cyber espionage, direct investment, and influence operations to enhance China’s comprehensive national power.

  • DHS Awards $4.2 Million to U.S. Small Business for Homeland Security R&D

    DHS S&T announced the award of 29 competitive research contracts to 25 small businesses across the United States to participate in Phase I of the DHS Small Business Innovation Research (SBIR) Program. Each project will receive up to $150,000 from the DHS SBIR Program to conduct proof-of-concept research over a five-month period to address specific homeland security technology needs.
