We all get defensive sometimes. For some animals, evolution has provided a highly effective mechanism for saying “back off!”. A puncture by a pair of venom-filled fangs gets the point across nicely. But one animal’s poison may be another’s cure. Some dangerous critters churn out compounds that can be synthesized into life-saving drugs. Meet the spiny, fanged, and oozing creatures who could help defend us against such illnesses as hypertension and kidney disease. Plus, the King of Pain - a scientist who has been stung by more than 80 species of insects in his pursuit of a better understanding of venom’s biochemistry. Find out which winged stinger scored the highest on his pain index. And, why the drug we need most may come from the quietest members of the biosphere: turning to plants for a new generation of antibiotics.

Venoms can ward off predators and disable prey, and some can even be chemically altered into life-saving drugs. Plus, the King of Pain - a scientist who has been stung by more than 80 species of insects to learn more about venom. He describes the worst.
