Heaviest Antimatter Found; Made in U.S. Atom Smasher

Heaviest Antimatter Found; Made in U.S. Atom Smasher
A tiny "big bang" set off in Long Island recently created a new type of antimatter that's literally off the charts, scientists announced last week.

Dubbed the antihypertriton, the newfound antimatter is the heaviest yet detected. What's more, it's the first type of particle that contains what's called an antistrange quark, which puts the antihypertriton in a new plane on the periodic table of elements.
