Jon-Paul Bingham, an assistant professor in the department of molecular biosciences and biological engineering at the University of Hawaii, has made a career of studying various species of the cone snail and characterizes them as "pretty horrific, pretty nasty."

But the venom, Bingham said, causes one surprising reaction in its victims: They feel no pain.

This venom's ability to cut off pain receptors has led to a second life as a powerful pain reliever called Prialt. The drug is 1,000 times more potent than morphine and is nonaddictive.

Prialt is just one example of the many ways venom components can be used therapeutically. Currently, six venom-derived medications have been approved by the U.S. Food and Drug Administration, but new technologies and research have shown how proteins and toxins within venom can provide key blueprints for treating a wider variety of ailments, including autoimmune disease, stroke and multiple sclerosis.
