• 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.

  • How Do Floods Become a Disaster?

    Since the 1990s, the number of fatalities from river floods has declined worldwide, but the amount of damage has risen sharply. Researchers attribute the decline in casualties to improved flood warning, technical protection measures and heightened hazard awareness.

  • It’s Official: July Was Earth’s Hottest Month on Record

    New global data show that July was the world’s hottest month ever recorded. The combined land and ocean-surface temperature was 1.67 degrees F (0.93 of a degree C) above the 20th-century average of 60.4 degrees F (15.8 degrees C), making it the hottest July since records began 142 years ago.

  • Debate over Origins of COVID-19 Continues

    At the end of the month, the U.S. intelligence community (IC) will submit a report to President Joe Biden offering the IC’s conclusions regarding the origins of COVID-1. The report is not likely to put an end to the debate, especially since China is refusing access to key materials and personnel.

  • Parasites Fight Chemical and Biological Weapons

    Harnessing parasites to help soldiers and first responders counter chemical and biological weapon attacks in war zones.

  • Lethal Autonomous Weapons and World War III: It’s Not Too Late to Stop the Rise of “Killer Robots”

    Scientists are pretty good at warning of the dangers facing the planet. Unfortunately, society is less good at paying attention. Artificial intelligence researchers like me have been warning of the advent of lethal autonomous weapons systems, which can make life-or-death decisions without human intervention, for years.

  • Small Towns Should Focus on Resilience

    With heatwaves, bushfires, and floods, small towns and their surrounding communities have confronted a combination of successive disasters fueled by climate change. And it’s predicted to only get worse. “So, the challenge for all of us, but particularly areas at increasing risk of climate-fueled disasters, is to get ahead of what’s coming,” says one expert. “We need to ask: what we can do to reduce or even prevent some of these disasters from happening?”

  • Earthquake Forecasts a Step Closer to Reality

    Earthquakes — like lightning — strike unpredictably. For decades, scientists have struggled to reliably give forecasts for major earthquake hotspots, but now, an international team of scientists has embarked on a new initiative to do just that.

  • Path Towards a Global Pathogen Early Warning System

    The world’s ability to detect, track, and analyze disease threats has improved considerably over the past several decades, the COVID-19 pandemic drove home a terrible reality: the systems we had in place are still deeply insufficient for halting the rapid spread of a novel pathogen fast enough to prevent a staggering level of damage.
