SUPER Technology Manages Intelligent Building Blocks for a More Reliable Electric Grid
As the United States transitions to cleaner energy and more U.S. consumers adopt electric vehicles, the grid is facing new power flow demands. Researchers are tackling this challenge by creating a new architecture to modernize the grid from the bottom up, starting with consumers and expanding to the entire power distribution system.

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.

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.

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.”
Enhanced Community Safety by Reimagining Gunshot Detection
A new gunshot detection system delivers new capabilities that significantly improve the response and management of outdoor shootings. The portable system employs two methods of detection for increased accuracy and reduced false positives.
Outsmarting Superbugs, One Germ at a Time
It’s an old story: Pathogen sickens humans. Humans create medicine. Pathogen evolves a way around the medicine. Humans are back to square one.
Using Quantum Physics to Secure Wireless Devices
From access cards and key fobs to Bluetooth speakers, the security of communication between wireless devices is critical to maintaining privacy and preventing theft. Unfortunately, these tools are not foolproof and information on how to hack, clone and bypass these systems is becoming easier to find.
Helping the U.S. Fast-track Hypersonic Conventional Weapons
Hypersonic weapons have been a top priority for modernizing the armed forces, with ultrafast, long-range and maneuverable munitions being touted as a revolutionary advance in modern warfare. The U.S. has fast-tracked their development and announced plans to field the first conventional hypersonic missile battery this year. Sandia National Lab is helping the U.S. achieve this goal.
U.S. Should Begin Laying the Foundation for New and Advanced Nuclear Reactors: Report
New and advanced types of nuclear reactors could play an important role in helping the U.S. meet its long-term climate goals, but a range of technical, regulatory, economic, and societal challenges must first be overcome.
