• Exploring the Possible Risks, Benefits of Geoengineering

    Climate change is creating impacts that are widespread and severe — and in many cases irreversible — for individuals, communities, economies, and ecosystems around the world. 2020 was one of the three warmest years on record, bringing with it a number of costly climate disasters, including the worst wildfire season ever recorded in the Western U.S., historic flooding in China and other parts of Asia, and severe droughts in South America. One of the approaches to avoid the most serious, possibly catastrophic impacts, of climate change is solar geoengineering.

  • Small Modular Reactors Competitive in Washington’s Clean Energy Future

    As the Clean Energy Transformation Act drives Washington state toward carbon-free electricity, a new energy landscape is taking shape. Alongside renewable energy sources, a new report finds small modular reactors are poised to play an integral role in the state’s emerging clean energy future.

  • Researchers Study Rooftop Solar Photovoltaic Grid-Tied System in Texas

    Scientists are continuously looking for alternatives to fossil fuel-based power plants to diminish the adverse effects of fossil energy sources on the environment and build reliability. Researchers are studying the viability of solar photovoltaic (PV) grid-tied systems on rooftops to fill that need.

  • Here’s What Scientists Learn from Studying Dangerous Pathogens in Secure Labs

    There are about 1,400 known human pathogens – viruses, bacteria, fungi, protozoa and helminths that can cause a person’s injury or death. But in a world with a trillion individual species of microorganisms, where scientists have counted only one one-thousandth of one percent, how likely is it researchers have discovered and characterized everything that might threaten people? Not very likely at all. And there’s a lot to be gained from knowing these microscopic enemies better.

  • Drone with 3D Mapping Tech Gives First Responders Near Real-Time Data

    ResponDrone’s new precision mapping abilities enable rescue teams to better understand their working environment in emergency situations such as fire, flood or any other natural disaster.

  • What Are “Ghost Guns,” a Target of Biden’s Anti-Crime Effort?

    It’s not expensive or difficult to produce large numbers of untraceable firearms in the United States. Whether for private use, sale on the criminal market or arming violent extremists, it’s actually startlingly cheap and easy to mass-produce firearms that police can’t track – what are often called “ghost guns.”

  • Early Wildfires Detection Systems Successfully Tested

    The Department of Homeland Security (DHS) Science and Technology Directorate (S&T) successfully tested four prototype technologies for early detection of wildfires in California this week. The test was the second phase of S&T’s Wildland Urban Interface (WUI) wildfire sensor technology program.

  • Difficult Tradeoffs: Climate Change and Dwindling Water Resources

    While a drought grips the southwestern United States and water supplies dwindle, decision-makers face increasingly difficult decisions about who, or what, gets water. Researchers have developed a model — the Framework for Assessment of Complex Environmental Tradeoffs (FACET) — designed to navigate and rigorously evaluate competing environmental, economic, and social impacts.

  • Evaluating Border Security Technologies on the Plains (and in the Skies) of North Dakota

    Safeguarding and securing the northern border against threats and illegal activities, such as human trafficking and smuggling of illicit drugs, presents unique challenges because of its various distinct landscapes and multiple points of entry into the country.

  • World's Largest Outdoor Earthquake Simulator Undergoes Major Upgrade

    A major upgrade to the world’s largest outdoor earthquake simulator reached a milestone mid-April when the facility’s floor—all 300,000 lbs of it—was put back into place. When completed this fall, the simulator will have the ability to reproduce multi-dimensional earthquake motions with unprecedented accuracy to make structures and their residents safer during strong shakes.

  • Researchers Look at Nuclear Weapon Effects for Near-Surface Detonations

    Researchers have taken a closer look at how nuclear weapon blasts close to the Earth’s surface create complications in their effects and apparent yields. Attempts to correlate data from events with low heights of burst revealed a need to improve the theoretical treatment of strong blast waves rebounding from hard surfaces.

  • Teaching Drones to Hear Screams from Catastrophe Victims

    In a disaster, time is of the essence when searching for potential victims who may be difficult to find. Unmanned aerial vehicles make the perfect platform for state-of-the-art technology allowing emergency crews to find those in need and provide situational awareness over a large area.

  • Envisioning Safer Cities with Artificial Intelligence

    Over the past several decades, artificial intelligence has advanced tremendously, and today it promises new opportunities for more accurate healthcare, enhanced national security and more effective education, researchers say. But what about civil engineering and city planning? How do increased computing power and machine learning help create safer, more sustainable and resilient infrastructure?

  • Increasing Pace, Intensity of Climate Hazards to Compound Security Threats: Report

    The other day the Expert Group of the International Military Council on Climate and Security (IMCCS) released its second annual World Climate and Security Report, which warns of the compound security threats posed by the convergence of climate change with other global risks, such as COVID-19.

  • How Virus Detectives Trace the Origins of an Outbreak – and Why It’s So Tricky

    Every time there is a major disease outbreak, one of the first questions scientists and the public ask is: “Where did this come from?” As an expert in viral ecology, I am often asked how scientists trace the origins of a virus. In my work, I have found many new viruses and some well-known pathogens that infect wild plants without causing any disease. Plant, animal or human, the methods are largely the same. Tracking down the origins of a virus involves a combination of extensive fieldwork, thorough lab testing and quite a bit of luck.
