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.

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

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 ...

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 ...

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

Type One Energy, which has developed an alternative to the tokamak magnetic confinement systems typically used in nuclear ...

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 ...

Russian researchers have proposed using boron-coated tungsten to protect fusion reactor walls during operation.

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 ...

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 ...
