At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same time. Matter no longer behaves like solid objects moving along clear paths.

Physicists have finally watched positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a tiny billiard ball. In a set of ...

X-ray free electron lasers (XFELs) are particle accelerators that create pulses of light of extremely short duration, similar to that of some lasers used in eye surgery. Combined with the X-ray energy ...

If you were asked to picture how electrons move, you could be forgiven for imagining a stream of particles sluicing down a wire like water rushing through a pipe. After all, we often describe ...

At the smallest scales of matter, nature behaves in ways that feel almost counterintuitive. Individual particles follow simple rules, but when they interact together, entirely new behaviors can ...

For over a decade, confusion over the size of the proton has held scientists back. Disagreeing measurements of the subatomic particle’s radius meant that scientists couldn’t test one of their key ...

Scientists have utilized the unique properties of quantum states of light to implement distributed, quantum-enhanced sensing.

Particle never before seen on Earth detected; it could come from a primordial black hole and the origin of the universe.

Sometimes, transporting electrons from one cell to another is a team effort. In electroactive bacteria, that team is a group ...

A mathematical equivalent of a microscope with variable resolution has shed light on why some atoms are exceptionally stable, ...
