frogs (Rana pipiens) raised in water with only one of these nine pesticides at 0.1 ppb appeared normal, though the fungicide propiconazole caused a small but significant increase in the time it took tadpoles to start metamorphosis. The insecticide te...

Discovery of genetic mutation in Florida beach mice suggests extinct mammoth had light and dark fur
...ding how color patterns, such as zebra stripes and leopard
spots, are generated in animals. And it raises the possibility that other vertebrates, such as mammoths, also evolved similar color variations using the same genetic mutation. In a companion paper published in the same issue of Science, researcher...
