In a single experiment, physicists have measured the "excess" emission of high-energy gamma rays from more than a dozen heavy, unstable atomic nuclei. Mapping the gamma-ray emissions of so many ...

Zap Energy, the Seattle-area startup that has spent nearly a decade chasing fusion power through an unconventional plasma technique, announced in June 2026 that it is adding traditional nuclear ...

China’s Changjiang Unit 3 achieves first criticality, bringing Hualong One reactor closer to operation ...

Interplanetary travel to Mars aboard nuclear-powered spaceships may sound like science fiction – yet NASA is planning to make it a reality. The Space Reactor-1 Freedom mission is scheduled for launch ...

California-based startup Deep Fission, which aims to place small modular reactors in boreholes a mile underground, has announced the delivery of its prototype reactor canister for its pilot project to ...

What if the high level nuclear waste generated by nuclear power plants could fuel a circular economy in the energy sector? Fast neutron reactors operating in a closed fuel cycle could make that happen ...

We don’t need any advanced propulsion to get to Mars,” says Robert Zubrin, founder of the Mars Society and the astronautical engineering company Pioneer Astronautics. “We can do it with chemical ...

Artificial intelligence (AI) holds promising potential for advancing nuclear energy production. These sophisticated computer systems mimic human logic in problem solving and decision making. With its ...

The mission is designed to test a compact tritium-powered device that could provide a steady source of low-power electricity for future spacecraft operating in environments where sunlight is limited.
