Twelve years ago, physicists first used an atom smasher to reproduce an exotic form of nuclear matter known as the quark-gluon plasma, which filled the universe microseconds after the big bang. But only now, after myriad subtle measurements, is a clear understanding of the stuff emerging, as physicists reported at a recent meeting. A standard model of the quark-gluon plasma is finally coming into focus, they say, and another decade or so of experiments should nail that model down.
