• Evacuating Outside the Lines

    Researchers at the University of Tsukuba show how extending evacuation options to shelters outside the borders of a city can help increase the efficiency of flood responses, which may reduce the disruption caused by natural disasters.

  • Regenerate: Biotechnology and U.S. Industrial Policy

    A revolution in biotechnology is dawning at the precise moment the world needs it most. Amid an ongoing climate crisis, fast-paced technological maturation, and a global pandemic, humans must find new ways to reduce greenhouse gas emissions, improve food security, develop new vaccines and therapeutics, recycle waste, synthesize new materials, and adapt to a changing world. The United States needs some form of industrial policy to promote its bioeconomy—one that is enshrined in democratic values and focused on improving access to four key drivers of bioeconomic growth: equipment, personnel, information, and capital.

  • Coming Soon: Solar-Powering First Responders?

    Fabric woven to harness solar power recently completed weaving trials. The fabric will ultimately be used to design high-functioning gear that can keep responders’ tech charged and ready.

  • Russian Casualties in Ukraine Invasion Top 75,000, U.S. Says

    More than 75,000 Russian soldiers — about half the force sent by Moscow to invade Ukraine in February — are believed to have been killed or wounded, a U.S. lawmaker said after attending a classified briefing with administration officials. The new numbers, if confirmed, would mean heavy losses for Russia as Ukraine presses ahead with a counteroffensive in the Russian-occupied southern portion of the country.

  • New Flood Maps Clarify the Risk Homeowners Face

    Flooding in urban areas cost Americans more than $106 billion between 1960 and 2016, damaging property, disrupting businesses and claiming lives in the process. Determining which areas are most likely to flood amid ever-changing land use and shifting rainfall and climate patterns can be expensive and complicated. New maps more realistically depict flood zones with less effort, lower costs.

  • An Elusive Shadow: State-by-State Gun Ownership

    Policy-makers are faced with an exceptional challenge: how to reduce harm caused by firearms while maintaining citizens’ right to bear arms and protect themselves. Meaningful legislation requires an understanding of how access to firearms is associated with different outcomes of harm, but this knowledge also calls for accurate, highly-resolved data on firearm possession, data that is presently unavailable due to a lack of a comprehensive national firearm ownership registry.

  • U.S. Youth Firearm Mortality Increases Over the Past Decade --Trends Differ Significantly Across States

    In 2020, firearms were the leading cause of death in children in the United States. Four states with stricter laws restricting gun access successfully reversed upward trajectories in youth gun deaths over the past decade.

  • 'Killer Robots': Will They Be Banned?

    A UN panel in Geneva remains split on whether to ban autonomous weapons, which don’t need a human to pull the trigger. Increasingly, these sorts of weapons are the stuff of a manufacturer’s promotional materials rather than science fiction movies. The war in Ukraine is complicating the conversation.

  • Alarming Trend Toward Political Violence

    A new report reveals alarming trends in attitudes toward violence, including political violence, in the United States. The survey is the first of its kind to explore the participants’ personal willingness to engage in specific political violence scenarios.

  • The World’s Largest Experimental Earthquake Infrastructure Facility

    The National Science Foundation (NSF) promotes research investments and technology that help recognize and mitigate the impacts of natural disasters across the U.S.“The ability to test infrastructure under a full range of motion is critical for unleashing new and pioneering research that can lead to effective, economical and innovative infrastructure designs and retrofitting strategies for existing infrastructure,” said NSF director Sethuraman Panchanathan.

  • Further Indications of Iran’s Renewed Interest in Maraging Steel for its Nuclear Enrichment Program

    Maraging steel bellows are well known to be used in the IR-2m centrifuge, but Iran has not made any of these centrifuges in years, leading to speculation that the bottleneck was the maraging steel. A recent report has revealed Iran’s renewed interest in metal bellows in its advanced centrifuges.

  • Climate Change, Land-Use Changes Increase Likelihood of Flood Events

    The German government estimates the total losses resulting from the disastrous floods in July 2021 at 32 billion euros. To improve future preparedness for such extreme events, researchers advise that risk assessments take greater account of the landscape and river courses, how they change, and how sediments are transported. In addition, projections show an increase in the spatial extent and frequency of such extreme events, as well as higher amounts of precipitation.

  • New Imaging Method Reveals Concealed Objects

    Imaging scenes that lie outside an observer’s direct line of sight could greatly enhance search and rescue missions, such as finding a lost child in an abandoned factory, as well as military and police surveillance operations, such as exposing a hidden terrorist or enemy stronghold. Using submillimeter radiation naturally emitted by objects and people, researchers see around corners.

  • Research Collaboration Informs International Classification of Firefighting as Carcinogenic

    The International Agency for Research on Cancer (IARC) recently classified occupational exposure as a firefighter as carcinogenic, changing the previous classification of possibly carcinogenic.

  • Ukraine's Homegrown Response to “Deadly” Chinese Drone Detection Tech

    Ukrainian forces have been using drones for tracking the movement of Russian forces, and armed drones to attack Russian tanks, trucks, and artillery batteries. But the effectiveness of the drones has been limited by a Chinese drone-tracking technology called AeroScope. Ukrainian drone enthusiasts have now developed their own drones which are capable of evading the Chinese detection technology.
