The comedian and his team of experts take a weird and wonderful look at life, death and extinction. Comedian Mark Steel learns how to deflect an incoming asteroid, neuroscientist Tali Sharot attends the first-ever taste test of beef grown solely in the lab and materials scientist Mark Miodownik takes a shotgun apart. Journalist Alok Jha asks whether pandas should be allowed to die out, as he examines if there are other species it would make more sense to invest effort in saving, and oceanographer Helen Czerski reports on the possibility of bringing extinct species back from the dead.
