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 ...

The fundamental nature of living things challenges assumptions that physicists have held for centuries.

A new study has measured the levels of indoor air pollution emitted by everyday home appliances, revealing which ones you ...

Scientists have managed to observe solar neutrinos carrying out a rare atomic transformation deep underground, converting carbon-13 into nitrogen-13 inside the SNO+ detector. By tracking two faint ...

On December 15, a football-field-sized balloon took flight over Antarctica, embarking on a mission that could reshape our understanding of the universe. Spearheaded by theUniversity of Hawaiʻi at ...

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, ghostly particles barely interacting with matter, may secretly be reshaping the fates of massive stars. New research suggests that as stars collapse, they form natural "neutrino colliders," ...

The largest particle detector of its kind has failed to turn up any hints of dark matter, despite searching for about a year. Known as XENON1T, the experiment is designed to detect elusive dark matter ...

About 1.2 miles beneath Antarctica, an underground observatory is hunting for "ghost particles." What it finds could reveal the unseen heart of a distant galaxy. Monisha Ravisetti was a science writer ...
