Comedian Adam Bloom joins us to discuss his appearance on a forthcoming Horizon TV documentary about what happens when you are deprived of all your senses. Find out how Adam coped with being locked up for 48 hours in a dark, silent nuclear bunker.
In the wake of the Human Fertilisation and Embryology Authority's decision to allow scientists to create hybrid human-animal embryos for stem cell research, Keith Campbell of the University of Nottingham tells us why the work is crucial. He also discusses the ethics of cloning animals for food. Would you eat a cloned steak?
And an intriguing story from Sweden of infidelity, multiple sexual partners and, er, plants. Heidi Hansson, a professor of English literature at Umea University, tells us why the binomial classification system for living creatures that we all now take for granted caused such a stir in the 18th century when naturalist Carl Linnaeus first introduced it.
All that, plus James Randerson and Nell Boase discussing why longer legs are more attractive to both sexes, a breakthrough in understanding leukaemia, a man who cloned himself and Nasa's new fitness video.
