Scientists at CERN have discovered an ultra-rare particle decay process, opening a new path to find physics beyond our understanding of how the building blocks of matter interact. Today the NA62 ...

There was a bump in the middle of the night. On June 14, 2012, Johns Hopkins physics and astronomy professor Andrei Gritsan analyzed data in a small meeting room at the CERN in Switzerland. He worked ...

The NA62 Collaboration has dramatically reduced the uncertainty in its measurement of an extremely rare particle decay, in results just presented at the 2026 La Thuile conference. The study of rare ...

Once in a very great while, an ephemeral particle called a kaon arises and then quickly decays away into three other obscure entities. Whether or not this happens in a particular way has very little ...

A new subatomic particle known as the Ξcc⁺ has been discovered at CERN’s Large Hadron Collider. This heavy proton-like ...

Scientists working at CERN’s Large Hadron Collider have identified a previously unseen charmed baryon, a heavy subatomic ...

Hairs on the toes of Mexican free-tailed bats light up under ultraviolet light, but the reason is unknown, Jason Bittel reported in “Mexican free-tailed bats’ toes glow in the dark” (SN: 8/28/24).

Scientists have demonstrated a new way to use high-energy particle smashups at the Relativistic Heavy Ion Collider (RHIC)—a U.S. Department of Energy (DOE) Office of Science user facility for nuclear ...

When it comes to the eventual end of our universe, cosmologists have a few classic theories: the Big Crunch, where the universe reverses its expansion and contracts again, setting the stars themselves ...
