Environmental toxins can cause obesity
Found this one through Grist:
While exposure in the womb to 100 parts per billion of the estrogenic drug diethylstilbestrol (DES) causes mice to become scrawny as adults, exposure to a much lower amount, 1 ppb, causes grotesque obesity. This photograph compares a control animal (left) to an animal exposed to a very small amount of DES in the womb (right).
