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 ...

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

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 fact that no one seems to have been killed by speeding blobs of dark matter puts limits on how large and deadly these particles can be, a study posted July 18 at arXiv.org suggests. “In the last ...

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

Tiny particles such as ice crystals or ash particles tend to oscillate as they settle through the atmosphere. In their experiments, the scientists were able to track non-spherical particles of size ...

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