Deadly spider venom can help heart attack survivors recover:

-
Fear of spiders, or arachnophobia, is one of the most common phobias. According to a new study, however, our eight-legged friends may turn out to be life savers. Researchers from the University of Queensland report that venom from one particular type of spider is the integral ingredient in a new life-saving treatment for heart attack victims. The spider in question, known formally as the Fraser Island (K'gari) funnel web spider, is considered among the world's most deadly. Ironically, a molecule extracted from this spider's venom is being used to produce a new drug candidate capable of both preventing heart attack damage and extending the life of donor hearts used for organ transplants. Study authors explain that the new drug actually blocks a "death signal" sent from the heart during a heart attack. (Study Finds)
