Bionic limbs

 Images Pro 3 Active Ankle Large Researchers from MIT, Brown University, and the Providence Veterans Affair Medical Center are launching a $7.2 million, five-year effort to develop bionic limbs:
"At the end of the project, the scientists hope to have created "biohybrid" limbs that will use regenerated tissue, lengthened bone, titanium prosthetics and implantable sensors that allow an amputee to use nerves and brain signals to move the arm or leg."
