There’s no harm talking to your houseplant, but will your chatter really help it grow? We look at various biological claims, from whether plants feel pain to the ability of cats to predict earthquakes. Feline forecasters, anyone? Also, when does understanding biology have important implications for health and policy? The arguments for and against genetically modified foods, and the danger of “pox parties” as a replacement for childhood vaccination. Plus, the history and current state of scientific literacy in the United States. When did we stop trusting science?
