Well, Solaris has handled many more than 48 cores for years. Too bad Solaris' future looks grim at the best, following Oracle's acquisition of Sun.
kokito writes "OSNews managing editor Thom Holwerda reviews Haiku, the open source successor of the Be operating system. According to the review, Haiku faithfully/successfully replicates the BeOS user experience and 'personality,' boasting very short boot times, the same recognizable but modernized GUI using antialiasing for fonts and all vector graphics as well as vector icons, a file system with support for metadata-based queries (OpenBFS) and support for the BeAPI, considered by some the cleanest programming API ever. The project has also recently released a native GCC 4.3.3 tool chain, clearing the way for bringing up-to-date ports of multi-platform apps such as Firefox and VLC, and making it easier to work on Haiku ports in general."

An anonymous reader writes "A number of amputees are now using a prosthetic arm that moves intuitively, when they think about moving their missing limb. Todd Kuiken and colleagues at the Rehabilitation Institute of Chicago surgically rearrange the nerves that normally connect to the lost limb and embed them in muscles in the chest. The muscles are then connected to sensors that translate muscle movements into movement in a robotic arm. The researchers first reported the technique in a single patient in 2007, and have now tested it in several more. The patients could all successfully move the arm in space, mimic hand motions, and pick up a variety of objects, including a water glass, a delicate cracker, and a checker rolling across a table. (Three patients are shown using the arm in the related video.) The findings are reported today in Journal of the American Medical Association."
