Nuclear Physics Used to probe Floridan Aquifer Threatened by Climate Change
Florida is known for water. Between its beaches, swamps, storms and humidity, the state is soaked. And below its entire surface lies the largest freshwater aquifer in the nation. As rising sea levels threaten coastal areas, scientists are using an emerging nuclear dating technique to track the ins and outs of water flow.

Hydrogen Can Play Key Role in U.S. Decarbonization
“Hydrogen is not really an energy source. It is rather an energy carrier or what we often call an energy vector,” says Berkeley Lab’s Ahmet Kusoglu. “So, you have to produce hydrogen from another energy source, store it, and then use or convert it. Hydrogen is a versatile and flexible energy carrier because it can be produced from various sources and for different applications. This flexibility is a key benefit of hydrogen versus other hydrocarbon fuels or energy storage technologies like batteries.”

Disrupting Asteroids to Protect the Earth
If an asteroid is on an Earth-impacting trajectory, scientists typically want to stage a deflection, where the asteroid is gently nudged by a relatively small change in velocity, while keeping the bulk of the asteroid together. Researchers have examined how different asteroid orbits and different fragment velocity distributions affect the fate of the fragments, using initial conditions from a hydrodynamics calculation, where a 1-Megaton-yield device was deployed a few meters off the surface of a 100-meter diameter asteroid.

Encryption Breakthrough Lays Groundwork for Privacy-Preserving AI Models
In an era where data privacy concerns loom large, a new approach in artificial intelligence (AI) could reshape how sensitive information is processed. New AI framework enables secure neural network computation without sacrificing accuracy.
AI-Controlled Fighter Jets May Be Closer Than We Think — and Would Change the Face of Warfare
By Arun Dawson
Could we be on the verge of an era where fighter jets take flight without pilots – and are controlled by artificial intelligence (AI)? US R Adm Michael Donnelly recently said that an upcoming combat jet could be the navy’s last one with a pilot in the cockpit.
AI and the Future of the U.S. Electric Grid

Enhanced Geothermal Systems: A Promising Source of Round-the-Clock Energy
By Julie Bobyock and Christina Procopiou
With its capacity to provide 24/7 power, many are warming up to the prospect of geothermal energy. Scientists are currently working to advance human-made reservoirs in Earth’s deep subsurface to stimulate the activity that exists within natural geothermal systems.
Experts Discuss Geothermal Potential
By Graeme Beardsmore and Rachel Webster, University of Melbourne
Geothermal energy harnesses the heat from within Earth—the term comes from the Greek words geo (earth) and therme (heat). It is an energy source that has the potential to power all our energy needs for billions of years.
Autonomous Weapon Systems: No Human-in-the-Loop Required, and Other Myths Dispelled
“The United States has a strong policy on autonomy in weapon systems that simultaneously enables their development and deployment and ensures they could be used in an effective manner, meaning the systems work as intended, with the same minimal risk of accidents or errors that all weapon systems have,” Michael Horowitz writes.
Are We Ready for a ‘DeepSeek for Bioweapons’?
Anthropic’s Claude 4 is a warning sign: AI that can help build bioweapons is coming, and could be widely available soon. Steven Adler writes that we need to be prepared for the consequences: “like a freely downloadable ‘DeepSeek for bioweapons,’ available across the internet, loadable to the computer of any amateur scientist who wishes to cause mass harm. With Anthropic’s Claude Opus 4 having finally triggered this level of safety risk, the clock is now ticking.”
