The International Thermonuclear Experimental Reactor (ITER) project has unveiled a new ‘Godzilla’ robot, which ...

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

Researchers at the DIII-D National Fusion Facility have identified a new method to tame ...

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 ...

Experiments show fusion plasma can stay stable at higher densities by controlling reactor walls, challenging long-standing limits.

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 ...

For billions of years, the sun reigned supreme as the only fusion reactor in our solar system, leveraging its immense gravitational pressure and intense heat to overcome an atomic nuclei’s natural ...

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 ...

Helion's Polaris device hit 150 million degrees C recently, a milestone that nudges the company toward its commercial power plant that will sell electricity to Microsoft.

A fusion reactor dismantled in the UK and reassembled in the Czech Republic celebrated its first plasma late last year. The $32 million device was handed over for a symbolic £1. A fusion reactor ...
