• Tornadoes and Climate Change: What a Warming World Means for Deadly Twisters and the Type of Storms That Spawn Them

    By John Allen

    The deadly tornado outbreak that tore through communities from Arkansas to Illinois on the night of Dec. 10-11, 2021, was so unusual in its duration and strength, particularly for December, that a lot of people including the U.S. president are asking what role climate change might have played – and whether tornadoes will become more common in a warming world. Both questions are easier asked than answered, but research is offering new clues.

  • On the Move: How Nations Address Climate-Driven Migration

    One of the most consequential human responses to climate change is and will continue to be the mass movement of people. Rising temperatures which reduce agricultural opportunities can lead to mass migrations away from struggling communities. As the environmental impacts of climate change increase in scope and severity, more and more people will move to new places to preserve or enhance their lives and livelihoods. How do nations address, and plan to address, the growing wave of migrants fleeing their home countries in search for better living conditions?

  • Creating Dangerous Viruses in the Lab Is a Bad Way to Guard against future Pandemics

    In 2011, three top U.S. government scientists — Anthony Fauci, the head of the National Institute of Allergy and Infectious Diseases, Francis Collins, the head of NIH, and Gary Nabel, then a top official at Fauci’s institute – wrote that given the uncertainties regarding the emergence of new, pandemic-causing pathogens, “important information and insights can come from generating a potentially dangerous virus in the laboratory.” Laura H. Kahn writes that “There are other less risky ways of preventing pandemics than conducting gain-of-function research on pathogens.”

  • Fuzzy Nanoparticles: New Way to Design Tougher Ballistic Materials

    Researchers have discovered a new method to improve the toughness of materials that could lead to stronger versions of body armor, bulletproof glass and other ballistic equipment.

  • New Cyber Protections against Stealthy “Logic Bombs”

    Cybersecurity researchers proposed new ways to protect 3D printed objects such as drones, prostheses, and medical devices from stealthy “logic bombs.”

  • Helping Calculate Likelihood of Worst-Case Scenarios

    If you had to guess, what would you think is most likely to end all life on Earth: a meteor strike, climate change, or a solar flare? New statistical method could help accurately analyze low-probability, high-risk events such as earthquakes, pandemics, or meteor strikes.

  • Community-Based Solutions to Enhance Disaster Resilience

    The NSF announced a $15.9 million in awards to teams to conduct and evaluate ready-to-implement pilot projects that address community-identified challenges. A significant portion of the funds was awarded to projects focusing on resilience to natural disasters in the context of equipping communities for greater preparedness to and response after disasters such as floods, hurricanes and wildfires.

  • Feasibility, Cost, and Potential Impacts of Ocean-Based Carbon Dioxide Removal Approaches

    To better understand the potential risks and benefits of removing or sequestering atmospheric carbon dioxide using ocean-based interventions — for example, by cultivating seaweed on a large scale or manipulating nutrients in seawater — the U.S. should undertake a new research program to learn more about how these methods could be used to mitigate the impacts of climate change.

  • California’s Water Supplies Are in Trouble as Climate Change Worsens Natural Dry Spells, Especially in the Sierra Nevada

    By Roger Bales

    California is preparing for a third straight year of drought, and officials are tightening limits on water use to levels never seen so early in the water year. Especially worrying is the outlook for the Sierra Nevada, the long mountain chain that runs through the eastern part of the state. California’s cities and its farms – which grow over a third of the nation’s vegetables and two-thirds of its fruit and nuts – rely on runoff from the mountains’ snowpack for water.

  • Cooking Material-Storage Containers to Assess Fire Safety

    Researchers have completed a series of tests on specially designed stainless-steel containers used by the Department of Energy for storage and transportation of hazardous materials. Even at 2000 degrees, the sealed, stainless-steel containers did not split open.

  • Ground Improvement Technique Ahead of Earthquakes

    Helping engineers better understand and predict the “liquefaction” hazard during earthquakes and more reliably mitigate it.

  • Balance of Power—Building a Resilient Electric Grid

    Events such as blackouts and outages are increasing in frequency as the nation’s infrastructure ages and climate change leads to extreme weather events. Hotter, wetter summers and harsher winters require more reliance on heating and cooling utilities, placing higher stress on the nation’s electric grid. Newtechnology can ‘help keep the lights on’ during emergencies.

  • Microgrids May Hold the Key to Grid Resilience

    The aging energy grid is being pushed to the breaking point. Power outages from extreme weather alone cost anywhere from $2 billion to $77 billion per year. And some isolated communities still rely on diesel generators for electricity, since powerlines don’t reach them. Grid expansion isn’t an option—in most cases, the economics don’t make sense. When the main grid falls short, the right mix of renewables offers local, low-carbon power.

  • Getting the Asteroid Before It Gets Us

    By Colleen Walsh

    Last week, the stuff of Hollywood blockbusters became a reality when NASA launched its Double Asteroid Redirection Test (DART), a small spacecraft that will smash into an asteroid sometime in September or October to try to alter its path.

  • New Generation of Grid Emergency Control Technology

    Grid operators face big challenges and big opportunities when it comes to managing through emergency conditions that disrupt power service. The increasing number of power outages in the United States cost an estimated $30-50 billion and affect millions of customers each year. A real-time adaptive system can safeguard the grid against costly disruptions.
