All of these new developments don’t mean that the sun is ready to give up its fusion monopoly, as many significant ...

Engineers at the UK’s STEP (Spherical Tokamak for Energy Production) program have successfully tested ...

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

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 ...

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 ...

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 ...

Avalanche has raised $29 million in fresh funding to pursue its unique approach to fusion power, which can currently fit on a ...

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 ...

Getting a significant energy return from tokamak-based nuclear fusion reactors depends for a large part on plasma density, but increasing said density is tricky, as beyond a certain point the plasma ...

NIIEFA has tested a high-temperature superconductor wire (HTSC) for the TRT tokamak, achieving record current and magnetic field parameters.
