• Smartphone Network Offers Inexpensive Earthquake Early Warning

    A new study demonstrates how Earthquake Early Warning using smartphone technology can be both inexpensive and effective for millions of people. 

  • Closing the Skills Gap in the Cyber Workforce

    There are currently more than three million unfilled cybersecurity jobs globally, and, as high-profile incidents like the Solar Winds attack demonstrate, it is vital to address that shortage. But it is difficult for organizations to find and recruit the cyber talent they need.

  • Delivering Aid to Disaster Scenes with Hydrogen Fuel Cell-Powered Vehicles

    DHS S&T, along with other government agencies, is working on the design and creation of the “H2Rescue” emergency vehicle. The H2Rescue is an innovative new truck that can be a lifeline to responders and community members during times of chaos and uncertainty because the H2Rescue is fully powered by a hydrogen fuel cell.

  • Machine Learning Helps in Earthquake Risk Prediction

    When that solid ground turns to liquid — as sometimes happens during earthquakes — it can topple buildings and bridges. The phenomenon is known as liquefaction, and it was a major feature of the 2011 earthquake in Christchurch, New Zealand. New framework applies big data, supercomputing to soil liquefaction.

  • Wildfires Threaten California’s Power Grid

    Wildfires blazed through California, Arizona, and Oregon, driven by winds and a lack of humidity.. Death Valley in California’s Mohave Desert hit 128 degrees Fahrenheit. Utility officials in Oregon were keeping a weary eye on the Bootleg Fire which is raging out of control in southern Oregon and threatening Path 66 — a vital electric line corridor linking California with the Oregon power grid. The blaze in Oregon threatens the power lines which carry power to California.

  • Most Buildings Were Designed for an Earlier Climate – Here’s What Will Happen as Global Warming Accelerates

    By Ran Boydell

    Architects and engineers design buildings and other structures, like bridges, to operate within the parameters of the local climate. The structures are built using materials and following design standards which can withstand the range of temperatures, rainfall, snow, and wind which are expected, plus any geological issues such as earthquakes, subsidence, and ground water levels. When any of these parameters are exceeded, chances are some aspects of the structure will fail.

  • Automatically Finding Buffer Overflow Vulnerabilities

    A typical buffer overflow occurs when a computer program receives a request to process more data than its physical memory is capable of handling all at once and places the excess into a “buffer.” The buffer itself has a finite capacity, so if the buffer can’t handle the excess, it “overflows,” or crashes.

  • Detecting Floods from Space Using Artificial Intelligence

    Observing the Earth from space provides valuable information for flood-related decision-making on the ground.

  • Accurately Predicting Impact of Storms, Sea-Level Rise on Coasts

    The combination of extreme storms and rises in sea levels as a result of global climate change are posing serious threats to coastal communities. The Forecasting Coastal Evolution (ForCE) model has the potential to be a game-changing advance in coastal evolution science.

  • Are Buyouts a Viable Tool for Climate Adaptation?

    By Elise Gout

    Sea level rise, and the resulting storm surges and floods, have made managed coastal retreat – the purposeful movement of people, buildings, and other infrastructure away from the coast – an option which more and more communities are considering. The need for adaptive solutions to the growing coastal challenges is clear, but questions remain as to where buyouts by the government of vacated property can and should fit in.

  • Face Off for Best ID Checkers

    A face matching test has been updated to find super-recognizers who can help prevent errors caused by face recognition software. The type of professional roles that involve face identification and that could benefit from the test include visa processors, passport issuers, border control officers, police, contract tracers, as well as security staff in private industry.

  • Recent Technology Cost Forecasts Underestimate Pace of Technological Change

    A comparison of observed global energy technology costs, with forecasts generated by models and forecasts predicted by human experts, showed that both forecasting methods underestimated cost reductions. This suggests that decisions based on forecasts may be overestimating the cost of climate mitigation and points to the need to further improve forecasting methods.

  • Why “Nuclear Batteries” Offer a New Approach to Carbon-Free Energy

    By David L. Chandler

    Much as large, expensive, and centralized computers gave way to the widely distributed PCs of today, a new generation of relatively tiny and inexpensive factory-built reactors, designed for autonomous plug-and-play operation similar to plugging in an oversized battery, is on the horizon. These microreactors, trucked to usage sites, could be a safe, efficient option for decarbonizing electricity systems.

  • More Than 100 Deaths Tied to Heat Wave in Pacific Northwest

    More than 100 deaths in Oregon, Washington, and y British Columbia may have been caused by hyperthermia, authorities say, as the region continues to experience record-shattering high temperatures.

  • With Cyberattacks Growing More Frequent and Disruptive, a Unified Approach Is Essential

    By Yasser Morgan

    Coordinated cyberattacks can create massive disruptions to infrastructure and supply chains. New treaties are needed to prevent cyberwarfare, but it’s challenging to predict technological advances.
