Such behaviour is strikingly different from all previously known layered superconductors and indicates that reduced dimensionality in these compounds is not a prerequisite for "high-temperature" superconductivity.

Holy petaflop
New supercomputer's blazing speed attracts researchers

The IBM Roadrunner, built for the Los Alamos National Laboratory in New Mexico, hums along during sustained runs at 1.105 quadrillion calculations per second, according to the TOP500 Supercomputers list. "That's a lot of power," said Kevin Wohlever, director of supercomputing operations at the Ohio Supercomputer Center, where an IBM cluster of computers can make 21.9 trillion calculations per second.
