• 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.

  • Assessment of Ocean Warming Highlights Future Climate Risks

    More than 90 percent of heat generated by global warming is absorbed by the oceans, and the Atlantic Ocean and southern oceans are warming much faster than the Pacific Ocean and Indian Ocean. A warmer ocean leads to more intense storms, more deadly rainfall and flooding, and more powerful typhoons and hurricanes.

  • Why Not Use Space Mirrors for Reflecting Sunlight to Cool the Planet?

    Given the potential consequences of climate change and a danger of reaching irreversible “tipping points,” there is an argument to be made that all options should be carefully considered. Sending giant mirrors into space to reflect solar radiation away from the Earth is one such option. The problem is that the many such geoengineering approaches have been so taboo that there is not enough information from researchers to definitively decide what options are still viable.

  • Signatures of Alien Technology Could Be How Humanity First Finds Extraterrestrial Life

    Technosignatures are signs of technology originating from beyond Earth. No astronomer has ever found a confirmed technosignature, so it’s hard to say what will be the first sign of alien civilizations. Many astronomers have thought a lot about what might make for a good signal, but ultimately, nobody knows what extraterrestrial technology might look like and what signals are out there in the Universe.
