Smart Microgrids Can Restore Power More Efficiently and Reliably in an Outage
It’s a story that’s become all too familiar — high winds knock out a power line, and a community can go without power for hours to days, an inconvenience at best and a dangerous situation at worst. Engineers developed an AI model that optimizes the use of renewables and other energy sources to restore power when a main utility fails.

Seaworthy Solution Yields Green Energy, Fresh Water
Engineers have refined a model that not only cultivates green energy, but also desalinates ocean water for large, drought-stricken coastal populations.By pumping seawater to a mountaintop reservoir and then employing gravity to send the salty water down to a co-located hydropower plant and a reverse osmosis desalination facility, science can satisfy the energy and hydration needs of coastal cities with one system.

Researchers Fabricate Commercial Grade Uranium Dioxide HALEU Fuel
As the world clamors for carbon-free power, U.S. nuclear reactor developers have responded with several advanced reactor designs. Nuclear energy from light water reactors already ranks among the safest forms of energy production, and most advanced reactors will use safety systems that rely on the laws of physics to virtually eliminate the possibility of a serious accident.

National Opportunities to Remove Carbon Dioxide at the Gigaton Scale
Researchers have completed a first-of-its-kind high-resolution assessment of carbon dioxide (CO2) removal (CDR) in the United States. The report concludes that with today’s technologies, removing 1 billion metric tons of CO2 per year will annually cost roughly $130 billion in 2050, or about 0.5% of current GDP.

New Insights on Community Resilience and Adaptation
A major weather event such as a hurricane or wildfire can have lasting, visible impacts on communities, but the longer-term, compounding effects of a changing climate can be harder to see. There are ways that communities can adapt and become more resilient as the climate changes.

Using AI to Help Dams Run Smarter
Korea faces a precipitation peak during the summer, relying on dams and associated infrastructure for water management. However, the escalating global climate crisis has led to the emergence of unforeseen typhoons and droughts, complicating dam operations. In response, a new study has emerged, aiming to surpass conventional physical models by harnessing the potential of an artificial intelligence (AI) model trained on extensive big data.

What if Law Enforcement Could ‘See’ Through Walls?
New technology allows law enforcement to easily and safely identify whether any individuals are inside a room when direct line-of-sight is not an option. This is especially critical when conducting breaching operations, searching for trafficked individuals or in potential hostage situations, where the device gives responders precious intelligence and situational awareness while reducing the risk of physical harm to themselves.

Modeling Geothermal Systems’ Viability
Geothermal power has a lot of promise as a renewable energy source that is not dependent on the sun shining or the wind blowing, but it has some obstacles to wide adoption. One challenge is that a limited number of locations in the U.S. naturally have the right conditions: hot rock relatively close to the surface and with plentiful groundwater to heat up. Web tool looks belowground for an economically viable renewable energy source.

Huawei’s New Mate 60 Phones Are a Lesson in Unintended Consequences
In October 2022, the Commerce Department introduced a set of export-control measures designed to prevent the use of American chip technology for Chinese military purposes. Rules were also imposed that aimed to restrict China’s semiconductor production to older 14-nm technology. These controls have had varying degrees of success, but the 14-nm restriction is one of the more overt failures, as the 7-nm chips in the new Huawei’s Mate 60 phones shows.

How a Small Caribbean Island Is Trying to Become Hurricane-Proof
Climate change is increasing the frequency and intensity of extreme weather events in the Caribbean and for small islands such as Dominica (not to be confused with the much larger Dominican Republic) it is an existential threat. Unlike larger islands like Cuba or Jamaica, a single storm hitting Dominica can damage the entire country – and the topography and small size of the island imposes hard limits on its ability to adapt.

Autonomous Vehicle Technology Vulnerable to Road Object Spoofing and Vanishing Attacks
Researchers have demonstrated the potentially hazardous vulnerabilities associated with the technology called LiDAR, or Light Detection and Ranging, many autonomous vehicles use to navigate streets, roads and highways. The researchers have shown how to use lasers to fool LiDAR into “seeing” objects that are not present and missing those that are – deficiencies that can cause unwarranted and unsafe braking or collisions.
Tantalizing Method to Study Cyberdeterrence
Tantalus is unlike most war games because it is experimental instead of experiential — the immersive game differs by overlapping scientific rigor and quantitative assessment methods with the experimental sciences, and experimental war gaming provides insightful data for real-world cyberattacks.
Prototype Self-Service Screening System Unveiled
TSA and DHS S&T unveiled a prototype checkpoint technology, the self-service screening system, at Harry Reid International Airport (LAS) in Las Vegas, NV. The aim is to provide a near self-sufficient passenger screening process while enabling passengers to directly receive on-person alarm information and allow for the passenger self-resolution of those alarms.
