China's "artificial sun" reactor has broken its own world record for maintaining super-hot plasma, marking another milestone in the long road towards near-limitless clean energy.
The Experimental Advanced Superconducting Tokamak (EAST) nuclear fusion reactor maintained a steady, highly confined loop of plasma — the high-energy fourth state of matter — for 1,066 seconds on Monday (Jan. 20), which more than doubled its previous best of 403 seconds, Chinese state media reported.
