Did matter-antimatter mix yield molecules?

`Physicists suspect they have created the first molecules from atoms that meld matter with antimatter.

Allen Mills of the University of California, Riverside, and his colleagues say they have seen telltale signs of positronium molecules, made from two positronium atoms1.

Positronium is an other-worldly mimic of hydrogen. In a hydrogen atom, a negatively charged electron moves around a proton, which has a positive charge. The electrical force of attraction between the two subatomic particles holds them together.’
