Canadian startup General Fusion has been working on its unique approach to producing clean energy through nuclear fusion for two decades, and it's now got something major to show for it. The company ...

A breakthrough experiment revealed how plasma turbulence spreads heat inside fusion reactors, solving a decades-old problem ...

SMART (Small Aspect Ratio Tokamak), the world's only fusion reactor with 'negative triangularity' constructed at the University of Sevilla in Spain, produced its first plasma. This is an important ...

Physicists have spent decades chasing two grand technological dreams: harnessing fusion power and uncovering the nature of ...

Many tokamaks use what is called positive triangularity plasma to produce energy, but past experiments have found that the inverse of this triangularity could be more stable. A new compact tokamak ...

China is racing forward in its effort to pave the way in fusion energy science, and state-sponsored media reported earlier this week that one of the country’s next-gen reactors is now under ...

Could future fusion reactors also serve as laboratories in which to manufacture dark matter? That’s the provocative question ...

The interiors of fusion reactors can get seriously chaotic. But for obvious reasons—like extreme temperatures and pressures—researchers aren’t typically able to peek directly inside a reactor. Some ...

General Fusion announced on Tuesday that it had successfully created plasma, a superheated fourth state of matter required for fusion, inside a prototype reactor. The milestone marks the beginning of ...

Nuclear fusion, which operates on the same principle that powers the sun, is expected to become a sustainable energy source for the future. To achieve fusion power generation, it is essential to ...

It’s rarely appreciated just how much more complicated nuclear fusion is than nuclear fission. Whereas the latter involves a process that happens all around us without any human involvement, and where ...

In February, France's WEST nuclear fusion reactor made a big step toward getting clean, star-like energy for everyone. The machine held superheated plasma for 1,337 seconds, or just over 22 minutes.
