Trouble at the LHC

A major helium leak has shut down work at the CERN Large Hadron Collider.

In order to fix the problem, the machine will have to be warmed up from its operating temperature of minus 271.3 degrees Celsius (minus 456.3 degrees Fahrenheit), spokesman James Gillies said.

"Because the LHC is a superconducting machine that works at very low temperatures, in order to get in and fix it we've got to warm it up, then we go and fix it, and then we cool it down again, and that's a process that's likely to take two months," he said.

The $9 billion machine was only in operation for ten days before the leak shut it down. Link -Thanks, Carrie!
