France’s WEST tokamak reactor just held fusion plasma steady for 22 minutes and 17 seconds at temperatures three times hotter than the sun’s core. Your smartphone battery worries might finally have an ...

Inside a French fusion experiment, a metal more associated with lightbulb filaments than star power just did something extraordinary. Tungsten, long considered too brittle and temperamental for the ...

The machines at their center, called tokamaks, have evolved from experimental curiosities into instruments capable of sustaining confined plasma – matter so hot it mimics the ...

All of these new developments don’t mean that the sun is ready to give up its fusion monopoly, as many significant ...

The sun-mimicking technology known as nuclear fusion hopes to create “limitless” energy by smashing light nuclei together using immense heat, but containing such hot plasma is proving tricky. A ...

In the hills of southern France, far from daily political drama and market headlines, a single engineering move is quietly reshaping what “possible” looks like for nuclear fusion. At the ITER site ...

Nuclear fusion promises a green and infinitely renewable supply of energy—if we can harness it. Fusion happens all the time inside the sun. But to recreate the process on Earth, we must control ...

Dark matter seems invisible, but it makes up most matter, and we have evidence that it gives the cosmos its shape. Now ...
