CNN Political Ticker: All politics, all the time Blog Archive - GOP senator: McCain betrayed Republican principles

DeMint offered a long list of complaints about McCain's record in the Senate and on the campaign trail.

"McCain, who is proponent of campaign finance reform that weakened party organizations and basically put George Soros in the driver's seat," DeMint said. "His proposal for amnesty for illegals. His support of global warming, cap-and-trade programs that will put another burden on our economy. And of course, his embrace of the bailout right before the election was probably the nail in our coffin this last election. And he has been an opponent of drilling in ANWR, at a time when energy is so important. It really didn't fit the label, but he was our package."

But will it be powered purely by wind and solar energy?

OAK RIDGE - Oak Ridge National Laboratory had promised a breakthrough performance from its newly arrived Cray XT5 supercomputer, but Monday's announcement was still a stunner.

The "Jaguar" system is now the world's fastest computer for science research, capable of 1.64 petaflops - or 1.64 quadrillion mathematical calculations per second. A quadrillion is equivalent to 1,000 trillion.

"It's going to be really exciting times in terms of the kind of science that's being done," Thomas Zacharia, ORNL's computational science leader, said Monday.

Jaguar will be used for studies of global climate change, as well as development of alternative energy sources and other types of scientific problem-solving that previously could not be attempted.
