• New Ways to Assess Climate Change Impacts on Agriculture

    Scientists agree climate change has a profound impact on U.S. agricultural production, but estimates vary, making it hard to develop mitigation strategies. Two agricultural economists take a closer look at how choice of statistical methodology influences climate study results. They also propose a more accurate and place-specific approach to data analysis.

  • Investments in Nature Needed to Stop the Next Pandemic: Experts

    A group of leading scientific experts from the U.S., Latin America, Africa and South Asia released a report outlining the strong scientific foundations for taking actions to stop the next pandemic by preventing the spillover of pathogens from animals to people. Among other findings, the report notes that protecting forests and changing agricultural practices are essential, cost-effective actions to prevent pandemics.

  • Emberometer Gauges Threat of Wildfire-Spreading Embers

    Wildfire fronts spread not only on the ground, but also from above, as the fire launching volleys of glowing embers, also known as firebrands, into the air. These specks of burning debris can glide for up to about 24 miles before landing. They cause up to 90 percent of home and business fires during wildfires.

  • Optical Fibers Detect Earthquakes

    Optical fibers, the underground optical cables that transmit a lot of information at a time, are familiar to us. But few would associate optical fibers with earthquake detection.

  • U.S. Most Widely Felt Earthquake: 10 Years On

    Ten years ago, millions of people throughout the eastern U.S. felt shaking from a magnitude 5.8 earthquake near Mineral, Virginia. No lives were lost, and it was not the strongest earthquake to have occurred in the eastern U.S., let alone the western U.S., but the Virginia earthquake was likely felt by more people than any earthquake in North America’s history.

  • Tracking Water Storage: Improving Water Management During Floods, Droughts

    Researchers have created a balance sheet for water across the United States – tracking total water storage in 14 of the country’s major aquifers over 15 years. With longer-term droughts and intermittent intense flooding expected in the future, particularly in the arid western U.S., there is rising concern about overtaxing water resources in the region, especially for irrigated agriculture.

  • Taliban to Gain Control over $1 trillion Mineral Wealth

    To date, the Taliban have profited from the opium and heroin trade. Now the Islamist group effectively rules a country with valuable resources that China needs to grow its economy. Afghanistan’s mineral riches will also bolster China’s dominance in rare Earth elements.

  • What the “Lyme Wars” Can Teach Us about COVID-19 and How to Find Common Ground in the School Reopening Debate

    As schools reopen, concerns over a delta-driven surge in cases, vaccine ineligibility for children younger than 12 and varying opinions about mask use in school settings loom large.The Lyme controversy offers four lessons on how parents, school districts, elected officials and scientists can find common ground – and a path forward – in the 2021-2022 school year.

  • An App for Safe Handling of Drones

    Nearly every day, U.S. Customs and Border Protection (CBP) agents come across drones that may have been used to facilitate the movement of illicit drugs or people across the southern border. These drones usually carry smuggled narcotics and often contain surveillance cameras; however, they could easily be modified to carry other threats or hazards.

  • Small Modular Reactors May Mitigate Climate Change

    The consequences of carbon emissions from the large-scale burning of fossil fuels are all around us, from relentless wildfires to scorching heatwaves to devastating floods to destructive megadroughts. There is renewed interest in nuclear energy, specifically in the new generation of small modular reactors.

  • Studying Spent-Fuel Canister to Support Long-Term Storage

    Nuclear waste is stored in more than sixty dry-cask storage sites in thirty-four states. These facilities store the majority of the more than 90,000 metric tons of nuclear waste in the United States, including nearly 80,000 tons of spent nuclear fuel.

  • Artificial Intelligence Helps Unlock Extreme Weather Mysteries

    A new machine learning approach helps scientists understand why extreme precipitation days in the Midwest are becoming more frequent. It could also help scientists better predict how these and other extreme weather events will change in the future.

  • With Redesigned “Brains,” W88 Nuclear Warhead Reaches Milestone

    The W88 nuclear warhead entered the stockpile in late 1988 and is deployed on the Navy’s Trident II submarine-launched ballistic missile system onboard Ohio-class ballistic missile submarines. The weapon was beyond its original design life, and several updates were required to address aging issues and to maintain its current state of readiness.

  • New Clean Energy Technology Extracts Twice the Power from Ocean Waves

    A prototype technology holds the promise of doubling the power harvested from ocean waves, in an advance that could finally make wave energy a viable renewable alternative. The untapped potential of ocean wave energy is vast—it has been estimated that the power of coastal waves around the world each year is equivalent to annual global electricity production.

  • Urban Development and Greenhouses Gasses Will Fuel Urban Floods

    When rain began falling in northern Georgia on September 15, 2009, little did Atlantans know that they would witness epic flooding throughout the city. Researchers are asking whether a combination of urban development and climate change fueled by greenhouse gasses could bring about comparable scenarios in other U.S. cities. Based on a new study, the answer is yes.
