Engineers at the UK’s STEP (Spherical Tokamak for Energy Production) program have successfully tested ...

By exceeding a long-standing density barrier, China’s EAST fusion reactor proved that tokamaks can pack way more atoms into its plasma before destabilizing.

Experiments show fusion plasma can stay stable at higher densities by controlling reactor walls, challenging long-standing limits.

China's EAST nuclear fusion reactor has successfully kept plasma stable at extreme densities, passing a major fusion milestone and potentially bringing humanity closer to wielding near-limitless clean ...

After many years of experiments, the U.K. Atomic Energy Authority (UKAEA) is decommissioning the world's longest-running fusion tokamak. The project housing this machine is known as the Joint European ...

“Many foundational problems in perception, multimodal reasoning, and agent coordination are being actively addressed in 2026.

Engineers at the DV Efremov Institute of Electrophysical Apparatus (NIIEFA), a branch of Rosatom, ...

A viable nuclear fusion reactor — one that spits out more energy than it consumes — could be here as soon as 2025. That's the takeaway of seven new studies, published Sept. 29 in the Journal of Plasma ...

Nuclear fusion involves heating atoms to extreme temperatures until they fuse. It promises abundant clean energy without the ...

The Bezos Earth Fund is funding a new effort to standardize nuclear reactor builds as electricity demand surges.

The existing U.S. nuclear power fleet could deliver nine reactors' worth of added capacity. EPRI experts explain how—and what comes next.
