A persistent asymmetry in fusion exhaust has challenged researchers for years. New simulations show that plasma core rotation, working together with cross-field drifts, determines where particles land ...

Reactors designed to produce energy from the fusion of atoms could have an unexpected scientific side benefit. An international team of researchers has shown that low-mass dark-sector particles, such ...

China breaks a historic barrier in nuclear fusion, bringing the dream of nearly infinite energy closer to reality.

For decades, nuclear fusion has held the promise of clean, limitless energy. However, one persistent challenge has slowed progress: the inability to reliably contain the high-energy particles needed ...

Scientists have long seen a puzzling pattern in tokamaks, the doughnut-shaped machines that could one day reliably generate electricity from fusing atoms. When plasma particles escape the core of the ...

Commonwealth Fusion Systems (CFS), a spinout from Massachusetts Institute of Technology, announced plans on Tuesday to build the world's first grid-scale commercial nuclear fusion power plant in ...

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 ...

In August last year the control room at General Atomics had something to celebrate. A room full of scientists stood by their computers, took cell phone photos and cheered as their nuclear reactor ...

Fusion energy promises a future of clean, nearly limitless power, but building reactors that can survive the extreme ...

At 4 a.m., while most of New Jersey slept, a Princeton Plasma Physics Laboratory (PPPL) physicist sat at his computer connected to a control room 3,500 miles away in Oxford, England. Years of ...
