The use of pesticides has decreased in the US by more than 40 percent since 1992, but the emergence of more-potent chemicals means that they are far more damaging to many species.
After a nearly 30-year hunt, researchers have shown that a neurotoxin generated by cyanobacteria on invasive plants is responsible for eagle and waterbird deaths from vacuolar myelinopathy.
