BPA induces sterility in roundworms
Bisphenol A does a real number on the genes responsible for successful reproduction in a 1-millimeter-long soil-dwelling roundworm. And that suggests BPA might pose similar risks to people because geneticists are finding that this tiny critter can be a remarkably useful “lab rat” — predicting impacts in mammals, including us.
