The matter we normally encounter, and are comprised of, has nuclei of prontons and neurtons which contain no strange quarks. It was known that such matter could exist, but using the Solenoidal Tracker at RHIC they detected a couple dozen instances of antihypernuclei. The "Z" axis of the Period Table has already extended in the positive direction by the concept of hypernuclei, but now this new discovery extends it in the negative direction for this new type of "strange" antimatter which may exist in the core of collapsed stars and may provide insight into why our universe appears to be made almost solely of matter and not antimatter.
