Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle—never seen before and predicted not ...

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

Physicists are eyeing charged gravitinos—ultra-heavy, stable particles from supergravity theory—as possible Dark Matter candidates. Unlike axions or WIMPs, these particles carry electric charge but ...

After years of careful investigation, researchers working on the Micro Booster Neutrino Experiment (MicroBooNE) have determined that a ...

After decades, Chinese researchers confirm the Migdal effect that may help reveal dark matter particles.

Ah, dark matter. Creator of the universe, sculptor of galaxies, great brewer of coffee (probably). There seems to be nothing it can’t do, or isn’t responsible for, but there’s just one problem: Where ...

The hypothetical faster-than-light particle known as the tachyon may marry with the special theory of relativity, according to a team of physicists, making its existence more plausible. Tachyons are a ...

Columnist Natalie Wolchover checks in with particle physicists more than a decade after the field entered a profound crisis.

Inside the Large Hadron Collider, protons slam together at nearly the speed of light, creating a brief fireball of quarks and gluons that looks, at first glance, like pure chaos. New work from CERN ...

Always seeking harmony, man sees the universe—for a few brief moments—as a pleasingly simple machine. Then curiosity about the nature of matter gets the better of him. Democritus conceived matter as ...

Add Yahoo as a preferred source to see more of our stories on Google. Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that ...
