Ray Kurzweil will be interviewed live on NPR's Science Friday on Friday, December 23rd, from 3:00 to 4:00 pm Eastern time. Kurzweil is a leading proponent of what may be called the transhumanist movement in nanotechnology, believing it will help us transcend many of our human constraints, even death. Host Ira Flatow will be talking with Kurzweil about his latest book, The Singularity Is Near: When Humans Transcend Biology.

Air times will vary depending on where you're located. A full listing of radio stations that syndicate Science Friday can be found here.
