A major physics experiment has uncovered evidence for a strange new form of matter, where a fleeting particle gets trapped ...

The Large Hadron Collider (LHC) is in the business of discovering new subatomic particles—and business is good. The team at CERN recently announced the discovery of a new particle, named Ξcc⁺ or Xi-cc ...

A three-decade study in southern China reveals that the physical arrangement of soil particles has a greater influence on the biochemical nature of stored carbon than the type of fertilizer applied. A ...

A new type of particle may have shown up independently at two particle accelerators, physicists say. The particle, made of four quarks (the ingredients of protons and neutrons), appears to represent a ...

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 ...
