Diggester sends this quote from Nature News: "Physicists at CERN's Large Hadron Collider have achieved the hottest man-made temperatures ever, by colliding lead ions to momentarily create a quark gluon plasma, a subatomic soup and unique state of matter that is thought to have existed just moments after the Big Bang. The results come from the ALICE heavy-ion experiment — a lesser-known sibling to ATLAS and CMS, which produced the data that led to the announcement in July that the Higgs boson had been discovered. ALICE physicists, presenting on Monday at Quark Matter 2012 in Washington DC, say they have achieved a quark gluon plasma 38% hotter than a record 4 trillion degree plasma achieved in 2010 by a similar experiment at Brookhaven National Laboratory in New York, which had been anointed the Guinness record holder."
