Scientists at a nuclear fusion reactor in China recently surmounted an important obstacle in operating reactor vessels at high density. They pushed plasma density 65% beyond a special threshold, entering a stable state that overcomes a long-standing barrier to achieving burning plasma, the stage where a fusion reaction becomes self-sustaining. Fusion power mimics what happens…
