The new research presented in Physical Review Letters explains the complex process that requires not just energy to escape, but also tight maneuvering through a quantum door. Despite its widespread ...

Electrons are still almost perfectly round, a new measurement shows. A more squished shape could hint at the presence of never-before-seen subatomic particles, so the result stymies the search for new ...

The electron, against predictions, appears to be perfectly round, raising questions about one of the fundamental building blocks of the universe. An electron's shape refers to that of the cloud of ...

Harvard researchers have studied and observed solid hydrogen under pressure at low temperatures. With increasing pressure we observe changes in the sample, going from transparent, to black, to a ...
