CERN Physicists Generate Hottest Man-Made Temperatures Ever: ~5.5 Trillion K 107

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."

Huge Arctic Ice Shelf Breaks Off 736

knarfling writes "CNN is reporting that a chunk of ice shelf nearly the size of Manhattan has broken away from Ellesmere Island in Canada's northern Arctic. Just last month 21 square miles of ice broke free from the Markham Ice Shelf. Scientists are saying that Ellesmere Island has now lost more than 10 times the ice that was predicted earlier this summer. How long before the fabled Northwest Passage is a reality?"
