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 — ...

With a carefully designed experiment and a handful of tin atoms, University of Tennessee, Knoxville's physicists have found a ...

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

One of the defining breakthroughs that set quantum physics apart from classical physics was the realization that matter behaves very differently at ...

A rainbow reveals with colors what otherwise remains hidden: light is "refracted" by transparent matter, in this case water ...

The FBI is leading a multi-agency investigation into at least a dozen deaths and disappearances of US scientists since 2022, many with ties to sensitive national security research. Lawmakers are ...

A leading physicist argues the brain may operate like a quantum system—and that enhancing it could create humans who perceive ...

Physicists in Leiden have recreated Thomas Young’s iconic double-slit experiment using gigahertz sound waves on gallium arsenide, revealing both parallels and differences with light. The study found ...

Researchers have shown that surprisingly large metal particles can behave according to quantum mechanics, existing in multiple states at once.

A ball tossed into the air follows a path that classical physics can track with confidence. Shrink that ball down to the size ...

For the first time, physicists have observed that 'holes' in light can move faster than the light itself. They're known as ...
