  • New, Portable Antenna Could Help Restore Communication After Disasters

    By Laura Castañón

    Researchers from Stanford and the American University of Beirut have developed a lightweight, portable antenna that can communicate with satellites and devices on the ground, making it easier to coordinate rescue and relief efforts in disaster-prone areas.

  • Previously Unknown Pathway to Batteries with High Energy, Low cost and Long Life

    By Joseph Harmon

    The road from breakthrough in the lab to practical technology can be a long and bumpy one. The lithium-sulfur battery is an example. It has notable advantages over current lithium-ion batteries powering vehicles. But it has yet to dent the market despite intense development over many years. That situation could change in the future, as scientists discover surprising pathway to better lithium-sulfur batteries by visualizing reactions at the atomic scale.

  • U.S. Lawmakers Push for Limits on American Investment in China Tech

    By Katherine Gypson

    U.S. lawmakers renewed calls Wednesday to pass bipartisan legislation that would restrict American investment in Chinese technology. A pending bill, H.R. 6349, would target specific technology sectors, like AI and quantum computing, which are empowering China’s military development and surveillance.

  • How the Drone War in Ukraine Is Transforming Conflict

    By Kristen D. Thompson

    From drones that fit in the palm of the hand to drones weighing more than 1,000 pounds (454 kilograms), Ukraine has built and acquired a diverse fleet of remotely piloted aircraft to complicate and frustrate Russia’s advances. The constantly evolving scope of this technology and its ever-growing use signal not only the potential for drones to level the playing field in the Russia-Ukraine war, but also their ability to influence how future conflicts are waged.

  • Iceland Battles a Lava Flow: Countries Have Built Barriers and Tried Explosives in the Past, but It’s Hard to Stop Molten Rock

    By Iceland Battles a Lava Flow: Countries Have Built Barriers and Tried Explosives in the Past, but It’s Hard to Stop Molten Rock

    Fountains of lava erupted from the Sundhnúkur volcanic system in southwest Iceland on Jan. 14, 2024, invading the outskirts of the coastal town of Grindavík. Humans have tried many ways to stop lava in the past, from attempting to freeze it in place by cooling it with sea water, to using explosives to disrupt its supply, to building earthen barriers. It’s too soon to say if Iceland’s earthworks will succeed in saving Grindavík, a town of about 3,500 residents, and a nearby geothermal power plant.

  • Don’t Bring a Patriot to a Drone Fight—Bring Fighter UAVS Instead

    By Paul Maxwell

    Recent conflicts such as the war in Ukraine and the 2020 war in Nagorno-Karabakh demonstrate the growing importance of unmanned aerial vehicles. Naturally, there have been attempts to defeat this new threat. No matter the defense mechanism chosen, there just are not enough systems to provide sufficient protection against swarms of UAVs. The solution for this dilemma is to take the next step in UAV evolution: air superiority drones.

  • Hybrid Urban Water Sourcing Model

    By Patrick Kurp

    Houston’s water and wastewater system could be more resilient with the development of hybrid urban water supply systems that combine conventional, centralized water sources with reclaimed wastewater. Reclaimed wastewater could make supply systems more resilient.

  • “Killer Robots” Are Coming, and UN Is Worried

    By Liz Mineo

    Long the stuff of science fiction, autonomous weapons systems, known as “killer robots,” are poised to become a reality, thanks to the rapid development of artificial intelligence. In response, international organizations have been intensifying calls for limits or even outright bans on their use. Human rights specialist lays out legal, ethical problems of military weapons systems that attack without human guidance.

  • California’s Salton Sea Region a Rich Domestic Lithium Resource

    The United States currently has limited capabilities to recover, refine, and produce domestically sourced lithium, meaning nearly all lithium for U.S. needs must be imported. The most comprehensive analysis to date quantifying the domestic lithium resources in southern California’s Salton Sea region found that the total resources in the region could contain more than 3,400 kilotons of lithium, enough to support over 375 million batteries for electric vehicles (EV).

  • A Huge Battery Has Replaced Hawaii’s Last Coal Plant

    By Julian Spector

    Plus Power’s Kapolei battery is officially online. The pioneering project is a leading example of how to shift crucial grid functions from fossil-fueled plants to clean energy.

  • Kibbutz Farmers Defy Death and Ruin with Robotic Greenhous

    By Abigail Klein Leichman

    Two Gaza-area farms join with agricultural robotics startup to restart and upgrade their operations despite having suffered personal loss and injury.

  • Saving Seconds, Saving Lives: NIST-Funded Challenge Crowns Winners in 3D Tracking Technology

    NIST has awarded $1.9 million to six teams for innovative 3D tracking solutions in the final phase of a competition. The winning designs combine localization and biometric monitoring, using sensors affixed to first responders’ equipment. This competition is part of an $8 million NIST-funded initiative to address first responders’ need for improved tracking in emergency settings where GPS falls short.

  • Researchers Release Open-Source Space Debris Model

    By Janine Liberty

    With the escalating congestion in low Earth orbit, driven by a surge in satellite deployments, the risk of collisions and space debris proliferation is a pressing concern. Conducting thorough space environment studies is critical for developing effective strategies for fostering responsible and sustainable use of space resources. The MIT Orbital Capacity Assessment Tool lets users model the long-term future space environment.

  • Identifying Types of Cyberattacks That Manipulate Behavior of AI Systems

    AI systems can malfunction when exposed to untrustworthy data – what is called “adversarial machine learning” — and attackers are exploiting this issue. New guidance documents the types of these attacks, along with mitigation approaches. No foolproof method exists as yet for protecting AI from misdirection, and AI developers and users should be wary of any who claim otherwise.
