kkleiner writes "The world's first human testing of a mind-controlled artificial limb is ready to begin. A joint project between the Pentagon and Johns Hopkins Applied Physics Laboratory, the Modular Prosthetic Limb will be fully controlled by sensors implanted in the brain, and will even restore the sense of touch by sending electrical impulses from the limb back to the sensory cortex. Last week APL announced it had been awarded a $34.5M contract with DARPA, which will allow researchers to test the neural prosthetic in five individuals over the next two years."

SimonTheSoundMan notes that Avatar is being pulled from screens in China for being too successful, and too provocative in its anti-authoritarian message. (The 3-D and IMAX versions will remain.) "The communist nation's state-run movie distributor China Film Group is unexpectedly yanking the James Cameron-directed blockbuster Avatar from 1,628 2-D screens this week in favor of a biography of the ancient philosopher Confucius starring Chow-Yun Fat. ... According to a report in the Hong Kong newspaper Apple Daily, the move was made at the urging of propaganda officials who are concerned that Avatar is taking too much market share from Chinese films and drawing unwanted attention to the sensitive issue of forced evictions."

theodp writes "Two years ago, David DeWitt and Michael Stonebraker deemed MapReduce a major step backwards (here are the original paper and a defense of it) that 'represents a specific implementation of well known techniques developed nearly 25 years ago.' A year later, the pair teamed up with other academics and eBay to slam MapReduce again. But the very public complaints didn't stop Google from demanding a patent for MapReduce; nor did it stop the USPTO from granting Google's request (after four rejections). On Tuesday, the USPTO issued U.S. Patent No. 7,650,331 to Google for inventing Efficient Large-Scale Data Processing."

CFTM writes "The New York Times is running an interesting article about how human memory works and the theorized adaptive nature of forgetfulness". From the article, "Whether drawing a mental blank on a new A.T.M. password, a favorite recipe or an old boyfriend, people have ample opportunity every day to curse their own forgetfulness. But forgetting is also a blessing, and researchers reported on Sunday that the ability to block certain memories reduces the demands on the brain when it is trying to recall something important. The study, appearing in the journal Nature Neuroscience, is the first to record visual images of people's brains as they suppress distracting memories. The more efficiently that study participants were tuning out irrelevant words during a word-memorization test, the sharper the drop in activity in areas of their brains involved in recollection. Accurate remembering became easier, in terms of the energy required."
