Quantum physics once shocked scientists by revealing that particles can behave like waves—and now, that strange behavior has ...

Positronium shouldn't last long enough to be interesting. It's an "atom" assembled from an electron and its antimatter twin — ...

Scientists have made the first experimental observation of matter wave diffraction in a short-lived electron-positron atom.

Physics is simple. In fact, it never ceases to astonish me how, with a few simple ideas from physics in your suitcase, you can travel from your own backyard to the most exotic realms of the universe, ...

The quantum physics of massive particles has intrigued physicists for more than 80 years, since it predicts that even complex particles can exhibit wave-like behaviour – in conflict with our everyday ...
