Physicists may have just cracked open a hidden side of the quantum world. For decades, every known particle was thought to ...

Muons are a key subatomic particle in the discovery of new physics, but after particle collision, they’re difficult to track.

A new study, published in the journal Physical Review Letters, suggests that some of the highest-energy cosmic rays could ...

But such measurements are notoriously challenging: the instruments used are themselves governed by quantum laws, and their interaction with particles can alter the very properties they are meant to ...

Human-made microbeads don’t always go with the flow. Under certain conditions, the artificial particles can align themselves with a fluid’s flow and then swim upstream, researchers report May 1 in ...

For decades, scientists have explored the enigmatic world of fundamental particles, uncovering the building blocks of our universe. But what if some of these particles, once deemed impossible, ...

The windy and chaotic remains surrounding recently exploded stars may be launching the fastest particles in the universe. Highly magnetic neutron stars known as pulsars whip up a fast and strong ...

Neutrinos are so tiny, so nearly massless, that they’re very difficult to isolate. But we know for sure that they’re produced ...
