Nuclear physicists question origin of radioactive beryllium in the solar system

Scientists have determined that a rare element found in some of the oldest solids in the solar system, such as meteorites, and previously thought to have been forged in supernova explosions, actually predate such cosmic events, ...

Madison Symmetric Torus operates stable plasma at 10 times the Greenwald Limit

If net-positive fusion energy is to ever be achieved, density is key: the more atomic nuclei crashing into each other, the more efficient the reaction will be. Nearly 40 years ago, Martin Greenwald identified a density limit ...
