No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...

Dark matter seems invisible, but it makes up most matter, and we have evidence that it gives the cosmos its shape. Now ...

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

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Every second, 100 trillion phantasmic little particles called ...

From the outside, the high-speed collisions of atomic nuclei inside particle accelerators like CERN’s Large Hadron Collider (LHC) may seem like they have very little in common with more mundane ...

The Standard Model of particles and interactions is remarkably successful for a theory everyone knows is missing big pieces. It accounts for the everyday stuff we know like protons, neutrons, ...

The W boson is heftier than anyone expected. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. An ultraprecise measurement of the mass of a ...

A phase change in the early universe and particles called HYPERs could make dark matter detectable in future experiments. When you purchase through links on our site, we may earn an affiliate ...

If dark matter is made from "dark" versions of the basic building blocks of ordinary matter, the world's largest particle accelerator should be able to pin it down, a new study suggests. When you ...

The Large Hadron Collider began smashing atoms together in 2009 and continues to throw up surprising insights into the fundamental building blocks of the universe. It’s via evidence from particle ...

Scientists at Fermilab’s MicroBooNE experiment have ruled out the existence of the elusive sterile neutrino, a particle proposed for decades to explain puzzling neutrino behavior. Their high-precision ...

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 ...
