China’s flagship fusion experiment has pushed plasma density beyond a limit that many physicists treated as a hard ceiling, jolting a field that has chased star power for decades. By holding an ...

China's Burning Plasma Experimental Superconducting Tokamak fusion facility (BEST) has entered a new construction phase as it speeds toward its 2027 target completion date. The state-run nuclear ...

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 ...

Chinese researchers report experimentally overcoming the Greenwald density limit in tokamak fusion reactors. The advance removes a major physics barrier toward sustained fusion and energy breakeven.

Beijing is pouring vast resources into fusion research, while the U.S. wants private industry to lead the way. The winner could reshape civilization. By Raymond Zhong Chris Buckley Keith Bradsher and ...
