University of Pittsburgh researchers found the commonly used weed killer Roundup altered tadpole hormones, resulting in larger tails that are similar to those that develop in tadpoles living in close proximity to predators. "This discovery highlights the fact that pesticides, which are important for crop production and human health, can have unintended consequences for species that are not the pesticide's target," said biological sciences professor Rick Relyea.
