Poison World, 8pm You don't want to mess with a black widow spider (above), one bite and you could be a gonner. This programme explores the role poisons play in the history of culture, the stories of people who have survived attacks and how deadly poisons can be used to our own advantage. It recreates the horrifying ordeal of Clive Brady, victim of the world's deadliest snake, the Taipan, and relives the story of Allan Blair's self-imposed torture from a black widow spider bite in one of the most bizarre experiments ever. Discover why the box jellyfish sting is so lethal and meet the master of pain, Justin Schmidt, who has a vast experience of insect venoms. Nature's toxins have also become wound into human cultural experience; poisonous plants and animals play an important role in the Haitian religion of voodoo, and the puffer fish's delicate poison is an expensive luxury to Japanese connoisseurs of Fugu. At the other extreme, venom is being used to cure people in bee and snake therapy. If you are a bit squeamish, give this programme a miss.
