Multiple companies aim to generate power by corraling plasma with twisted magnets

Even once researchers can reliably get more power out of a fusion reaction than they put in, they'll still need to overcome engineering challenges to scale up fusion energy.

After hitting a power-output milestone, fusion technology is ready to graduate from small-scale lab experiment to full-sized power plant.

The Korean Institute of Fusion Energy announced a new world record for the length of time it managed to sustain temperatures seven times hotter than the...

Diamond is the strongest material known. However, another form of carbon has been predicted to be even tougher than diamond. The challenge is how to create it on Earth.

We've been 'close' to achieving fusion power for 50 years. When will it actually happen?

TIME followed NIF scientists in the year after they achieved the biggest scientific breakthrough of the decade—successful fusion.

Scientists have made breakthroughs in nuclear energy. But what is nuclear fusion and how does it work? Here are 10 things to know about it.

Is fusion really the energy of the future? Michael Fumento explores some of the many false starts in the development of controlled nuclear fusion and considers its current prospects, including inertial and magnetic confinement, inertial electrostatic confinement, and compact reactors.

Last week, the Department of Energy said scientists had ignited a fusion reaction that created more energy than was needed to sustain it.

American scientists have announced what they have called a major breakthrough in a long-elusive goal of creating energy from nuclear fusion. The U.S. Department of Energy said Dec. 13 that for the first time — and after several decades of trying — scientists have managed to get more energy out

Nuclear fusion, infectious diseases and an incredible new space telescope were ongoing stories in 2022, but what were some of the other big scientific developments, discoveries and events of the year?

Researchers in the US have finally fulfilled an objective that was set decades ago: the achievement of "ignition"—getting more energy out than you put in—using nuclear fusion.

Take a visual tour of the National Ignition Facility to see how scientists used its powerful laser array to create what amounts to a miniature star.

The U.S. Department of Energy on Tuesday announced that a national lab in California made a "major scientific breakthrough"—namely, that it produced a nuclear fusion reaction that resulted in a net energy gain, a condition known as "ignition."
