• Climate Change-Driven Heat Waves Have Cost Global Economy Trillions Since the 1990s

    Massive economic losses due to sweltering temperatures brought on by human-caused climate change are not just a problem for the distant future. A new study has found that more severe heat waves resulting from global warming have already cost the world economy trillions of dollars since the early 1990s. The study says that measures protecting people on hottest days are needed now.

  • Hydropower Delivers Electricity, Even During Lengthy Droughts

    The megadrought in the Southwestern United States is the driest—and longest—in the last 1,200 years, depleting water reservoir levels to critically low levels over the past 22 years. Droughts particularly impact hydroelectric power dams as well as some thermoelectric power plants that require large amounts of water for cooling. But a new report suggests that the relationship between drought and hydroelectric power is more nuanced than it might seem. Drought-strained hydropower sustains 80 percent average power generation capacity.

  • Monitoring Potentially Hazardous Near-Earth Asteroids

    An enormous number of near-Earth asteroids are posing a potential hazard to our planet. Faced with potential threats of to Earth by asteroid impact, researchers have been focusing on asteroid defense. Monitoring of and early warning about near-Earth asteroids is the premise of planetary defense.

  • How China’s Military Plugs into the Global Space Sector

    China is using seemingly civilian and academic Chinese research institutions to advance its military goals in space. International organizations like the International GNSS Service need to be aware that even overtly civilian entities can be intertwined with the Chinese military. Collaboration with high-risk Chinese institutions must be done with extreme care to ensure data and products intended to support international science and commerce are not redirected towards unwanted military uses.

  • Batteries Without Critical Raw Materials

    The market for rechargeable batteries is growing rapidly, but the necessary raw materials are limited. Sodium-ion batteries, for example, could offer an alternative.

  • The Inferred Abundance of Interstellar Objects of Technological Origin

    Five years ago, astronomers noticed a large, strange-looking object streaking across space, tens of millions of miles from Earth. Its trajectory and speed indicated it originated from outside the solar system. Astronomers say there may be 4 quintillion alien spacecraft traveling in – and in and out of — our solar system. That’s 18 zeros, just so that you know.

  • A Drone Wing That Could Learn How to Sense Danger Faster

    The small domes that you press on your soda’s to-go cup lid may one day save a winged drone from a nosedive. Patterns of these invertible domes on a drone’s wings would give it a way to remember in microseconds what dangerous conditions feel like and react quickly.

  • Meeting Surging Demand for National Security Research

    Sandia National Laboratory is embarking on a major expansion of its network of academic partners to meet the surging demand for national security science and engineering. From 2015 to 2021, the Labs’ budget increased more than 50%, from $2.9 billion to $4.5 billion. Over the same period, the Labs increased its workforce by more than 25%, from 11,700 to 15,000. Still, the Lab says that it won’t meet its obligations just by hiring staff.

  • Purdue University Launches Institute for National Security

    Building on its years of growing engagement and collaboration with the defense, homeland security and intelligence communities, Purdue University is creating the Purdue Institute for National Security, a new interdisciplinary institute.

  • Looking to Move to a Galaxy Far, Far Away? Innovative System Evaluates Habitability of Distant Planets

    The climate crisis presents a huge challenge to all people on Earth. It has led many scientists to look for exoplanets, planets outside our solar system that humans could potentially settle. Computerized system classifies atmospheres of planets and identifies those suitable for future human settlements.

  • Artificial Intelligence and Extremism: The Threat of Language Models for Propaganda Purposes

    Recent large-scale projects in the field of Artificial Intelligence have dramatically improved the quality of language models, unfolding a wide range of practical applications. Language models are statistical models that calculate probability distributions over sequences of words. Language models can make many beneficial contributions, but they may also be misused by extremist actors for propaganda purposes.

  • Companies Weigh Fallout from U.S. Ban on Sending Chip Tech to China

    The new U.S. ban the transfer of advanced U.S. semiconductor technology to China affects not only U.S. firms that sell to China, but any company whose products contain American semiconductor technology. Semiconductor companies and other tech firms that count China among their largest single markets are facing potentially severe damage to their revenues.

  • Russia Working Hard to Acquire Sensitive Western Military Technology

    Russia has struggled for years, if not decades, to acquire sensitive Western technology and military hardware: everything from night-vision goggles for soldiers to powerful computer chips for advanced fighter jets. How successful the effort has been is an open question, but according to news reports and military analysts, sensitive Western technologies are widely employed in Russian weaponry and military equipment.

  • Battery Tech Breakthrough Paves Way for Mass Adoption of Affordable Electric Car

    If new car sales are going to shift to battery-powered electric vehicles (EVs), they’ll need to overcome two major drawbacks: they are too slow to recharge and too large to be efficient and affordable. Researchers develop new technique that charges EV battery in just ten minutes.

  • Faster-Developing, Wetter Hurricanes to Come

    Climate change sets the stage for hurricanes to rapidly intensify faster, bringing wetter storms to the U.S. Atlantic Coast and other coastlines. A warmer world heightens the risk of flooding.
