Cooling positronium with lasers

Most atoms are made from positively charged protons, neutral neutrons and negatively charged electrons. Positronium is an exotic atom composed of a single negative electron and a positively charged antimatter positron. It is naturally very short-lived, but researchers have now successfully cooled and slowed down samples of positronium using carefully tuned lasers. They hope this
