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

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 ...

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 ...

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, ...

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

The universe looks like it is mostly empty space. Remove the stars, planets, dust, and gas, and what remains is nothing at ...

Researchers propose a new theory for the origin of dark matter, the invisible substance thought to give the universe its shape and structure. Their mathematical models show that dark matter could have ...

Chalk up a potential third win for hypothetical particles called axions. If the subatomic particles exist, they could solve two pressing puzzles of particle physics: the source of the dark matter that ...

A clean home often looks like polished surfaces and organized shelves. True health happens at a microscopic level where air ...
