Scientists trap a single antimatter particle for months

Northwestern University researchers have trapped and contained a single positron — an antimatter particle — for months, a feat described in a new report. The achievement is drawing attention because holding individual antimatter particles stably for such long periods is extremely difficult and could advance studies of antimatter's properties. Many observers, including science journalists, have reacted with affection to the isolated particle even as they focus on the technical breakthrough.

Why now: A science journal publication on a rare antimatter-trapping achievement is prompting wide discussion among scientists and journalists.
