ABSTRACT breaks down mind-bending scientific research, future tech, new discoveries, and major breakthroughs.There are many stumbling blocks on the racetrack to nuclear fusion, the reaction at the core of the sun that combines atoms to make energy: Generating more energy than it takes to power the reactors, developing reactor-proof building materials, keeping the reactor free from impurities, and restraining that fuel within it, to name a few. Now, researchers from Princeton University and its P...
