Scientists operating the WEST tokamak successfully sustained a superhot plasma at astonishing temperatures for a record-breaking six minutes.
The achievement marks a major milestone in the journey towards viable fusion power.
The breakthrough hinged on the use of tungsten, the grayish-white metal commonly found in light bulb filaments.

CEA scientist Xavier Litaudon explained why this achievement with the tungsten tokamak is such a significant breakthrough.
That’s why this recent breakthrough at WEST is so promising.
As Remi Dumont, who coordinated the experiment, succinctly put it “a spectacular result.”
Major players are also doubling down on fusion’s promise.
