This will blow your mind. A team of physicists recently trapped a single antimatter particle for months — a delicate feat ...

A team of astronomers may have detected the gamma-ray signature produced when antimatter particles, or positrons, collide with electrons outside of the Milky Way for the first time. The findings, ...

These elusive and reactive particles have been challenging to hold on to and even more challenging to study, but a new method paves the way for tests on the differences between matter and antimatter.

Physicists trap and cool down positron for months to measure its 'magnetic moment' with extraordinary precision.
