Hugh Dennis judges ideas for human enhancement from Professor Alice Roberts, Marcus du Sautoy and the studio audience at Glastonbury festival. Simon Watt officiates with offerings from Mother Nature's buffet table. In this episode we discuss transcranial magnetic stimulation, how we know bees are good at maths and why there's never been a giraffe at the International Space Station.
