• Ultrafast Devices to Protecting the Grid from EMPs

    Scientists from Sandia National Laboratories have announced a tiny, electronic device that can shunt excess electricity within a few billionths of a second while operating at a record-breaking 6,400 volts — a significant step towards protecting the nation’s electric grid from an electromagnetic pulse.

  • Un-Earthing Planetary Defense

    This summer, NASA will launch its first mission to a metallic asteroid, 16 Psyche, located in the main asteroid belt between the orbits of Mars and Jupiter. Previous missions have explored rocky and icy asteroids, but Psyche’s composition is widely believed to consist of a considerable amount of metal. Studying extraterrestrial bodies could help defend Earth from future impact threats.

  • Drone Warfare Is Increasingly Sophisticated, Deadly

    Policymakers, legislators and military strategists must prepare for the consequences of other countries and actors such as the Islamic State using unmanned aerial vehicles, or drones, in the Ukraine-Russia conflict and others.

  • Food Crisis Due to Ukraine War Calls for Demand-Side Action

    The global food system is impacted by the war in Ukraine, adding to the direct humanitarian and security crisis caused by the Russian aggression. Ukraine and Russia are major producers of grains and fertilizers. Experts say that focusing on short-term supply-side solutions is not the way to go. Rather, changes to the demand side of the global food system can lead to both a more resilient and more sustainable global food system.

  • Artificial Intelligence’s Promise: Discovering New Rare-Earth Compounds

    Rare earth elements have a wide range of uses including clean energy technologies, energy storage, permanent magnets, defense technology, and much more. Artificial intelligence advances how scientists explore materials, and researchers have developed an AI-based framework for experimenting with compounds and understanding chemical instabilities.

  • Wildfires Devastate the Land They Burn, and They Are Also Warming the Planet

    The 2021 wildfire season broke records globally, leaving land charred from California to Siberia. The risk of fire is growing, and a recent report warned that wildfires are on track to increase 50% by 2050. These fires destroy homes, plant life, and animals as they burn, but the risk doesn’t stop there. Researchers detail how the brown carbon released by burning biomass in the northern hemisphere is accelerating warming in the Arctic and warn that this could lead to even more wildfires in the future.

  • How a Hurricane Fueled Wildfires in the Florida Panhandle

    The wildfires that broke out in the Florida Panhandle in early March 2022 were the nightmare fire managers had feared since the day Hurricane Michael flattened millions of trees there in 2018. It might sound odd – hurricanes helping to fuel wildfires. But Michael’s 160 mph winds left tangles of dead trees that were ready to burn.

  • Setting Carbon Management in Stone

    Keeping global temperatures within limits deemed safe by the Intergovernmental Panel on Climate Change means doing more than slashing carbon emissions. It means reversing them. And when it comes to carbon storage, some MIT scientists think the best solution is to find the fastest way to turn carbon into rock.

  • Texas Cold Snap Highlights Need for Improved Power Systems

    The greatest demand for electricity in Texas is traditionally during the hottest days of the year, when air conditioners turn on full blast to beat the heat. But in February 2021, an unusually long spell of cold weather took the region by surprise. With extreme weather events rising in frequency, the need for a prepared modern energy grid grows.

  • Warning: Objects in Driverless Car Sensors May Be Closer Than They Appear

    Researchers have demonstrated the first attack strategy that can fool industry-standard autonomous vehicle sensors into believing nearby objects are closer (or further) than they appear without being detected.

  • As Sea Levels Rise, Coastal Megacities Will Need More Than Flood Barriers

    Sea level rise is expected to worsen in the next few decades, especially for many of the world’s largest cities in lower and middle income countries of Africa, Asia and Latin America. These cities are already improving their infrastructure. But most of the focus remains on big engineering solutions (like flood walls and embankments) rather than a more holistic plans.

  • CO2 Could Be Stored Below Ocean Floor

    Climate change is one of the most pressing challenges facing humanity. To combat its potentially catastrophic effects, scientists are searching for new technologies that could help the world reach carbon neutrality. One potential solution that is drawing growing attention is to capture and store carbon dioxide (CO2) emissions in the form of hydrates under ocean floor sediments.

  • The Digital Skills Gap: What Workers Need for the Jobs of the Future

    The COVID-19 pandemic quickened the pace of digital development around the world, as everything from meetings to movie premiers went online. That may sound like a silver lining. For tens of millions of workers, it’s not. They don’t have the skills to compete.

  • War in Ukraine Could Cut Global Supply of Essential Elements for Making Green Technology

    The EU imports 40 percent of its natural gas from Russia, and nearly half of the five million barrels of crude oil Russia exports daily go to Europe. Decisive action by major economies to reduce coal, oil and gas imports from one of the world’s largest sources could accelerate the transition to green energy globally. But there’s a catch. Disruption to the supply of critical metals and other materials caused by the war in Ukraine could stall the roll-out of alternative technologies.

  • Electric Truck Hydropower: Flexible Solution to Hydropower in Mountainous Regions

    Mountain regions have a large potential for hydropower that cannot be harnessed effectively by conventional technologies. Researchers developed an innovative hydropower technology based on electric trucks that could provide a flexible and clean solution for electricity generation in mountainous regions.
