  • Governments Are Using Science Fiction to Predict Potential Threats

    From high-tech fighting machines to supercomputers and killer robots, science fiction has a lot to say about war. You might be surprised to learn that some governments are now turning their attention to these fantastical stories as a way to think about possible futures and try and ward off any potential threats.

  • Shutting Down Nuclear Power Could Increase Air Pollution

    Nearly 20 percent of today’s electricity in the United States comes from nuclear power. If reactors are retired, polluting energy sources that fill the gap could cause more than 5,000 premature deaths, researchers estimate.

  • More Frequent Hurricanes Raise Risk to U.S. East and Gulf Coasts

    Warming tropical waters can trigger changes in winds that both strengthen and push hurricanes to the U.S. East and Gulf coasts more often, boosting hurricane frequency by a third compared to current levels.

  • The Energy Transition Will Need More Rare Earth Elements. Can We Secure Them Sustainably?

    Decarbonizing the world’s power generation will require huge numbers of wind turbines, solar panels, electric vehicles (EVs), and storage batteries — all of which are made with rare earth elements and critical metals. Supplying these vast quantities of minerals in a sustainable manner will be a significant challenge, but scientists are exploring a variety of ways to provide materials for the energy transition with less harm to people and the planet.

  • Why China Has Edge on AI, What Ancient Emperors Tell Us About Xi Jinping

    Dictatorships and authoritarian regimes tend to trail more democratic and inclusive nations in fostering cutting-edge, innovative technologies, such as robotics and clean energy. Artificial intelligence may prove an exception, at least in China.

  • Buildings Left Sanding in Turkey Offer Design Guidance for Future Earthquake-Resilient Construction

    The Feb. 6, 2023, earthquakes in Turkey and Syria put to the test advanced building technologies that can minimize damage and keep buildings functioning after a quake. Several hospitals built with one such technology – called a seismic isolation system – survived the earthquakes with almost no harm.

  • Investigators May Be Able to Use Household Dust as a Forensic Tool

    A new study found it is possible to retrieve forensically relevant information from human DNA in household dust. After sampling indoor dust from 13 households, the researchers were able to detect DNA from household residents over 90% of the time, and DNA from non-occupants 50% of the time. The work could be a way to help investigators find leads in difficult cases.

  • The Time to Prevent Shortfalls in Critical Materials Is Now

    Rare earth elements are—despite their name—everywhere. They’re in your cellphone, your car, maybe even in a crown in your mouth. They’re in satellites, wind turbines, night-vision goggles, laser-guided missiles, and fighter jets. All of which makes China’s near-total domination of the rare earth market a matter of economic and national security concern.

The long view

  • U.S. Reliance on Chinese Drones: A Sector for the Next CHIPS Act?

    More and more lawmakers from both parties are beginning to pay attention to the issue of drones and national security. Different bills seek to regulate federal agency procurement and use of certain foreign-made unmanned aircraft systems (UASs), or drones. Annie I. Antón and Olivia C. Mauger write that “Building on the bipartisan consensus to enact the 2022 Creating Helpful Incentives to Produce Semiconductors and Science (CHIPS) Act, there is a compelling case that UASs should be a next sector for similar action.”

  • Quantum Cryptography Applications

    The development of quantum computing means that the use of classic cryptography for secure communications is in danger of becoming obsolete. Quantum cryptography, on the other hand, uses the laws of quantum mechanics to ensure total security. One example of this is quantum key distribution, which enables two parties to secure a message via a random secret key.
