Bruce Blumberg, associate professor of developmental and cell biology at the University of California at Irvine, has found a possible connection between exposure to industrial pollution and obesity. Stories here and here. Exposing female frogs to mild doses of the pollution — specifically, toxic compounds called obesogens – made them “really fat.” According to the story, they can be found in plastics used in drinking bottles and many other food-bearing materials. Of course, the animal that most greatly experiences the world through its skin –  the amphibian — is what led to this discovery.
