Striving for immortality: this week we explore the feasibility of eternal life. We talk to the UK's first man to have himself frozen for the future, a US doctor explains how a person can be resuscitated after an hour submerged in icy water, and physicist Michio Kaku speculates on the future existence of a "library of souls" where we live forever as a computer programme inside a robot. Plus, news of why knuckles go crack, how the brain decodes quickly and slowly repeating sounds, how Salmonella can be used to combat cancer and why men get competitive when it comes to sponsoring a woman.
