(From the Seattle Times). The development of sophisticated protheses and artifical replacements for failing organs continues to be overshadowed by advances in regenerative medicine and tissue engineering, but the science is moving forward. "The properties of artificial muscle are getting much closer to that of biological muscle ... At the University of California, Irvine, biomedical engineer William Tang and one of his students have launched a project to develop a prosthetic hand with artificial muscles. ... Implants also are in the works. Mohsen Shahinpoor, director of the Artificial Muscle Research Institute at the University of New Mexico, has designed an eye implant to correct bad vision."
