It took nearly a year of high-powered number crunching on various supercomputers, but researchers from UC Santa Cruz and the Institute for Theoretical Physics in Zurich have finally produced a computer simulation of a galaxy that looks much like our own.
Since 2007, IBM has been working with the University of Illinois at Urbana-Champaign to construct the world's fastest academic supercomputer. This week we learn that work has been mysteriously halted by IBM, which is taking back the parts it recently delivered to the school, giving U. of Illinois its money back, and ceasing work on the project just months before the massive computer is slated to be completed.
A Japanese supercomputer is now the world’s fastest, unseating the previous record-holder by nearly a factor of four. The K Computer, based at the RIKEN Advanced Institute for Computational Science (AICS) in Kobe, can perform 8 petaflops — that’s 8 quadrillion calculations per second.
When Watson was competing on Jeopardy!, its massive databanks were filled with encyclopedias, novels, film scripts, and history books. These days, Watson is more into medical journals and misspelled Yahoo Answers blog posts about weird rashes and vague abdominal pains. Watson is maturing, and prepping for his first non-trivia, real-world application: medical diagnoses. He's all *sniff* grown up!
New integrated circuits use photons to build fast and extremely power-efficient supercomputers

The speed of light is as fast as it gets, and IBM researchers are exploiting that fact to give supercomputers a boost. They've made the smallest-yet silicon chips that use light to transmit information.
The Department of Energy is getting a 10-petaflop supercomputer to help scientists design efficient electric car batteries, understand climate change and unravel cosmic mysteries.
The IBM-built system, nicknamed "Mira," will be operational at Argonne National Laboratory next year. At 10 quadrillion calculations per second, it will be twice as fast as today's fastest supercomputer and 20 times faster than Argonne's current model. If every person in the United States performed one calculation every second, it would take almost a year for them to do as many calculations as Mira will do in one second, according to IBM.
Remember Watson? We're currently at IBM's offices watching the world's best Jeopardy-bot take on Ken Jennings, the winningest human to play the game. Follow @PopSci on Twitter right now for the live blow-by-blow, and stay tuned for a full report later today.
The holidays may be driving video game console sales, but apparently so is the military. The Air Force Research Laboratory (AFRL) has strung together 1,760 PlayStation 3 gaming systems to create what it’s calling the fastest interactive computer system in the entire DoD, capable of executing 500 trillion floating point operations per second.
