This early work laid the groundwork for today’s fusion experiments. More famously—or infamously—in 1989, two researchers claimed they had achieved “cold fusion” by running deuterium oxide through a ...

Commonwealth Fusion Systems has raised almost $3 billion to solve one of the most vexing problems in technology—how to create ...

Today, many fusion reactors rely on deuterium and tritium—heavy isotopes of hydrogen—to power fusion reactions. But where did ...

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 ...
