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 ...

A nuclear fusion reactor in Germany has reached world record numbers for runtime. The tokamak dominates fusion research in 2025, but stellarators are making a comeback. A stellarator is still a donut ...

Nuclear fusion, the process that powers every star in the observable universe, has moved from theoretical physics into the realm of real laboratory results. On December 5, 2022, scientists achieved ...

The promise of nuclear fusion feels simple. Just as stars fuse hydrogen into heavier elements to produce energy, a fusion reactor generates massive amounts of energy by combining lightweight particles ...
