Cats may retain an aura of mystery about their smug selves, but that could change with scientists using a supercomputer to simulate the the feline brain. That translates into 144 terabytes of working memory for the digital kitty mind.

A supercomputer known as Jaguar has finally bested IBM's Roadrunner supercomputer in the biannual TOP500 list, but researchers have already begun looking into exascale supercomputers that consist of 100 million cores and run 1,000 times faster than Jaguar. Computerworld reports that the U.S. Department of Energy has begun holding workshops on the new supercomputers to run high-res climate models, develop smart grids and aid fusion energy design.

Until today, Google's Chrome OS has been little more than a wordy concept. Now, finally, we truly know what it is, what it looks like, and how it works. Here's the breakdown.

Server farms are undeniably awesome in that they store huge pools of data, enable such modern phenomena as cloud computing and Web-hosted email, and most importantly, make the Internet as it stands today possible. The downside: data centers get very, very hot. Cooling huge banks of servers doesn't just cost a lot, it eats up a lot of energy, and that generally means fossil fuels.

While the rest of the Web-savvy world fawns over breakthroughs in real-time search and pontificates on the future of social networking, Los Alamos National Labs is looking to the past. A team there is developing a "time traveling" Web browsing technology, dubbed Memento, that will allow users to find old versions of Web pages without trolling old archives.
