Zarf writes "Dr. Todd A. Kuiken and the Doctors of the Rehabilitation Institue of Chicago have successfully used the nerve endings from an amputee's lost arm to drive a bionic replacement. Details are in this CNN story. Although this isn't new surgical work it is a clever and practical use of existing technologies which hasn't been done before. It offers the promise of other interesting applications as well such as hands-free wheelchair use or even hands-free mousing. The doctors hope that in time this technology will lead to other bionic replacement limbs as well."
