New simulations from Princeton Plasma Physics Laboratory suggest that deliberately engineering plasma rotation inside tokamak fusion reactors could dramatically reduce the heat loads that destroy ...

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

A 13-foot robot nicknamed Godzilla is being engineered to assemble components inside ITER, the massive fusion reactor taking ...

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 ...

Here’s what you’ll learn when you read this story: The plasma density barrier is a mathematical limit to the density of plasma that can exist in a tokamak before destabilizing. A new study led by a ...

A nuclear fusion reactor in Germany has reached world record numbers for runtime. The tokamak dominates fusion research in 2025, but stellarators are making a comeback. A stellarator is still a donut ...

The stakes of the “race to fusion” are dramatic. Commercial fusion has the potential to deliver nearly unlimited energy by ...

This is where Godzilla earns its keep. Standing four meters tall and capable of lifting 2.3 metric tons, Godzilla is the ultimate testbed. Starting in March 2026, the robot will begin testing over 30 ...

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 ...

A joint research team from Hefei Institutes of Physical Science of the Chinese Academy of Sciences has successfully developed a continuous cryogenic pellet injection system for tokamak fueling. This ...
