The time is nigh for nuclear clocks. In a first, scientists have used a tabletop laser to bump an atomic nucleus into a higher energy state. It’s a feat that sets scientists on a path toward creating ...

The process of hurling hydrogen atoms at each other to create extremely hot plasma — also known as nuclear fusion — holds massive potential for filling humankind's energy supply. The tricky part is ...

Scientific discovery rarely arrives in a single, dramatic moment. It usually emerges through careful experiments, revised equations, unexpected field observations, and years of incremental progress.

Scientists just brought us one step closer to the dream of unlimited power. On November 17 at the Nevada National Security Site, a nuclear energy startup called Valar Atomics achieved zero-power ...
