A Tokyo University of Science team has observed first-order matter-wave diffraction of positronium passing through a few-layer graphene grating, the first direct evidence that the short-lived electron-positron atom behaves as one coherent quantum object and a step toward gravity tests on antimatter.

The BASE experiment at CERN successfully moved 92 antiprotons in a portable cryogenic trap across the laboratory's campus, demonstrating that antimatter can survive road transport and paving the way for precision measurements at facilities across Europe.
