A new exhibit at the American Museum of Natural History explores the weird and wonderful world of poisons. Curated by evolutionary biologist Mark Siddall, “The Power of Poison” recreates a Columbian forest filled with deadly natural toxins, delves into the history of criminal ;poisonings, and brings to life famous fictional characters to investigate the science behind mythical poisons. The exhibit, which opened Saturday and runs through August 20, 2014, ends by examining how otherwise-deadly toxins can be used in medicine.
