• Combatting Terrorism with Environmental DNA

    Forensic science experts are refining an innovative counter-terrorism technique that checks for environmental DNA in the dust on clothing, baggage, shoes or even a passport. The technique traces the source of dust on suspect articles to match a soil profile of a specific area or overseas country.

  • Climate Change Has Cost 7 years of Ag Productivity Growth

    By Blaine Friedlander

    Despite important agricultural advancements to feed the world in the last 60 years, a Cornell-led study shows that global farming productivity is 21 percent lower than it could have been without climate change. This is the equivalent of losing about seven years of farm productivity increases since the 1960s.

  • An AI-Based Counter-Disinformation Framework

    By Linda Slapakova

    There are different roles that AI can play in counter-disinformation efforts, but the current shortfalls of AI-based counter-disinformation tools must be addressed first. Such an effort faces technical, governance, and regulatory barriers, but there are ways these obstacles could be effectively addressed to allow AI-based solutions to play a bigger role in countering disinformation.

  • Decoding the “Black Box” of AI to Tackle National Security Concerns

    When the discussion involves the detection of nuclear explosions or the movement of materials that endanger the nation’s security, scientists, policy makers, and others demand to know the basis of AI-based insights. Explainable AI—understanding and explaining the reasoning behind AI decisions—is a growing priority for national security specialists.

  • New Initiative Aims to Ensure 5G Networks Are Reliable, Secure

    The transition to 5G will affect every device connected to the internet. Later this year, a team of Stanford researchers will demonstrate how a tight formation of computer-controlled drones can be managed with precision even when the 5G network controlling it is under continual cyberattack. The demo’s ultimate success or failure will depend on the ability of an experimental network control technology to detect the hacks and defeat them within a second to safeguard the navigation systems.

  • Batteries: Reshaping the Future of the Electric Grid

    Research begun at the Department of Energy’s Joint Center for Energy Storage Research and continued at spinoff company Form Energy may launch a new era of renewable energy.

  • The Cost of a Key Climate Solution

    Perhaps the best hope for slowing climate change – capturing and storing carbon dioxide emissions underground – has remained elusive due in part to uncertainty about its economic feasibility. Researchers have estimated the energy demands involved with a critical stage of the process.

  • A Sponge to Soak Up Carbon Dioxide in the Air

    Human activity is now leading to the equivalent of 40 billion tons of carbon dioxide emitted into the atmosphere each year, putting us on track to increase the planet’s temperature by 1.5 degrees Celsius over pre-industrial levels by 2040. Increasingly, scientists are recognizing that negative emissions technologies (NETs) to remove and sequester carbon dioxide from the atmosphere will be an essential component in the strategy to mitigate climate change.

  • Adding AI to Autonomous Weapons Increases Risks to Civilians in Armed Conflict

    Earlier this month, a high-level, congressionally mandated commission released its long-awaited recommendations for how the United States should approach artificial intelligence (AI) for national security. The recommendations were part of a nearly 800-page report from the National Security Commission on AI (NSCAI) that advocated for the use of AI but also highlighted important conclusions on key risks posed by AI-enabled and autonomous weapons, particularly the dangers of unintended escalation of conflict. Neil Davison and Jonathan Horowitz write that “The NSCAI recommends that the United States excludes the use of autonomous nuclear weapons.”

  • Solving Problems for the World’s Freshwater Supply

    Water’s value to society goes far beyond quenching thirst. An indispensable resource, it is required not only to sustain life, but also for economic prosperity. Water, for example, is needed to generate energy and to manufacture nearly everything, from food to clothes, cars and electronics. Our future economy and national security highly depend on the availability of clean water. But there is a limited supply of renewable fresh water when and where it is needed.

  • New Fire-Simulating Tool Could Improve In-Flight Fire Safety

    Some of the most dangerous fires are the ones you don’t see coming. That goes not only for fires in buildings but for those kilometers off the ground, aboard commercial airliners. Many aircraft have systems to detect fires early on, but fires that spark in their attics, or overhead compartments — spaces with curved ceilings, filled with air ducts, electrical wiring and structural elements — could potentially sneak past them.

  • Computer Chip Pitted against 500+ Hackers. The Chip Won.

    An “unhackable” computer chip lived up to its name in its first bug bounty competition, foiling over 500 cybersecurity researchers who were offered tens of thousands of dollars to analyze it and three other secure processor technologies for vulnerabilities. MORPHEUS technology from the University of Michigan emerged unscathed from a DARPA virtual hackathon.

  • Stepped-Up U.S. Investment in Fusion Energy

    An influential Department of Energy (DOE) advisory committee has recommended that the nation move aggressively toward the deployment of fusion energy, including investments in technology and equipment to support one of the missions of LLNL’s National Ignition Facility (NIF) — laying the groundwork for the development of inertial fusion energy (IFE).

  • Expanding Domestic Manufacturing of Secure, Custom Chips for Defense Needs

    DARPA announced the Structured Array Hardware for Automatically Realized Applications (SAHARA) program, which aims to expand access to domestic manufacturing capabilities to tackle challenges hampering the secure development of custom chips for defense systems. DARPA selected Intel and university researchers to automate conversion of Structured ASICs with leading-edge, domestic foundry capabilities for defense electronic systems.

  • Is It Worth Investing in Solar PV with Batteries at Home?

    Solar energy is a clean, renewable source of electricity that could potentially play a significant part in fulfilling the world’s energy requirements, but there are still some challenges to fully capitalizing on this potential. Researchers looked into some of the issues that hamper the uptake of solar energy and proposed different policies to encourage the use of this technology.
