Bionic Business

Available for over a year

The technology of bionics is advancing rapidly. We look at its commercial applications and ask where it will all lead. The BBC's Laurence Knight reports from a hospital in England that successfully restored sight to a blind person by using electronic implants. Also, Professor John Donoghue of the Wyss Center for Bio and Neuro-engineering in Geneva, Switzerland, tells presenter Manuela Saragosa about how chips may one day be able to listen to your thoughts, and Ramez Naam, a former Microsoft executive turned science fiction novelist, explains why in future the distinction between what is human and what is machine may become ever more blurred.
