• Is the Southwest Too Dry for a Mining Boom?

    Critical minerals for the clean energy transition are abundant in the Southwest, but the dozens of mines proposed to access them will require vast sums of water, something in short supply in the desert.

  • Clusters of Atmospheric Rivers Amp Up California Storm Damages

    When multiple atmospheric rivers hit California back-to-back, the economic damage from resulting rain and snowfall is three to four times higher than predicted from individual storms, a Stanford study finds. The insight could help water managers and disaster planners better prepare for future impacts of climate change.

  • A Non-Proliferation Solution: Using Antineutrinos to Surveil Nuclear Reactors

    Antineutrinos generated in nuclear fission can be measured to remotely monitor the operation of nuclear reactors and verify that they are not being used to produce nuclear weapons, scientists report. Thanks to a newly developed method, it is now possible to estimate a reactor’s operation status, fuel burnup, and fuel composition based entirely on its antineutrino emissions. This technique could contribute massively to nuclear non-proliferation efforts and, in turn, safer nuclear energy.

  • The Challenge of Cheap Drones: Finding an Even Cheaper Way to Destroy Them

    The sudden proliferation of inexpensive drones in Ukraine is a revolution in warfare. While they vary in size and capability, the  economics of defense are particularly stressed by the very cheapest ones, those adapted from civilian models or made with commercially available components.

  • Hydrogen Power Takes Drones to the Next Level

    Most drones run on electric batteries and can stay aloft no more than about 45 minutes when carrying just a few kilograms. HevenDrones has another solution.

  • 5 Technologies Keeping Cargo Ships Safe in Turbulent Times

    Due to Houthi attacks on cargo ships in the Red Sea, worldwide shipping is in trouble and the global supply chain faltering. These technologies can help.

  • Creating the Self-Healing Grid of the Future

    Self-healing electrical grids: It may sound like a concept from science fiction, with tiny robots or some sentient tech crawling around fixing power lines, but in a reality not far from fiction, a team of researchers is bringing this idea to life. What’s not hard to imagine is the potential value of a self-healing grid, one able to adapt and bounce back to life, ensuring uninterrupted power even when assailed by a hurricane or a group of bad guys.

  • Investors Are “Flying Blind” to Risk of Climate Lawsuits

    Polluting companies could be liable for trillions in damages from climate lawsuits. But few investors and regulators are taking these risks into account when evaluating companies’ climate-related financial risks. Experts call for an overhaul in how climate litigation risks are assessed and provides a new framework for doing so.

     

  • A Drone with Ears

    When a region is hit by a natural disaster, searching for survivors is complex work as buildings and roads may be damaged. The use of drones equipped with daylight cameras and thermal imaging cameras is therefore becoming increasingly widespread – except that if victims are trapped under rubble, they cannot be seen by these imaging sensors. Equipping drones with acoustic sensors allows rescue teams to identify and locate cries for help, clapping, or knocking signals.

  • Central Asia Key to Breaking China's Rare Earth Monopoly

    U.S. officials hoping to break China’s near monopoly on the production of rare earth elements needed for many cutting-edge technologies should engage the governments of Central Asia to develop high concentrations of REEs found in the region, says a new report.

  • Using Idle Trucks to Power the Grid with Clean Energy

    After analyzing energy demand on Alberta’s power grid during rush hour, researchers propose an innovative way to replenish electrical grids with power generated from fuel cells in trucks. Idled electric vehicles can act as mobile generators and help power overworked and aging electricity grids.

  • From New York to Jakarta, Land in Many Coastal Cities Is Sinking Faster Than Sea Levels Are Rising

    Sea level rise has already put coastal cities on notice thanks to increasing storm surges and even sunny day flooding at high tide. These challenges will continue to grow because global projections point to a mean sea level rise of at least one foot above year-2000 levels in a few decades. many cities are facing another factor making them even more vulnerable to rising waters: land subsidence.

  • Fake Biden Robocall to New Hampshire Voters Highlights How Easy It Is to Make Deepfakes − and How Hard It Is to Defend Against AI-Generated Disinformation

    Robocalls in elections are nothing new and not illegal; many are simply efforts to get out the vote. But they have also been used in voter suppression campaigns. Compounding this problem in this case is what I believe to be the application of AI to clone Biden’s voice.

  • Military AI: New Book Anticipates a World of “Killer Robots” — and the Need to Regulate Them

    As artificial intelligence advances, the weapons of war grow evermore capable of killing people without meaningful human oversight, raising troubling questions about the manner today’s and tomorrow’s wars will be carried out, and how autonomous weapons systems could weaken accountability when it comes to the potential violations of international law that attend their deployment. 

  • Taking Robots and AI to War at Sea

    Emphasizing that combination of AI and autonomous systems working in concert with crewed platforms—and with critical human oversight ‘on the loop’—is the logical path to meet a potential challenge of a much more capable and assertive adversary with ambitious plans across the Indo-pacific, and with a potential ability to interfere with Australia’s critical maritime trade.
