Antimatter

Researchers at Tokyo University of Science have demonstrated matter-wave diffraction in positronium, an exotic atom formed by an electron and its antimatter counterpart, a positron. This marks the first observation of quantum interference in such a system. The findings, published in Nature Communications, confirm positronium's wave-particle duality.

CERN's BASE experiment has begun more precise antiproton studies thanks to the recent first-ever truck transport of antimatter around the France-Switzerland site. Spokesperson Stefan Ulmer says moving 92 antiprotons away from production magnets is key to probing why the universe has more matter than antimatter.
