Time to Screen Your Sample Suppliers

This article from the New York Times details a story of the Karitiana Indians, an Amazon tribe in Brazil that agreed to let researchers collect blood samples from them in exchange for promises of medicine. They never saw the medicine, they say, and instead recently discovered that "their blood and DNA collected during that first visit are being sold by an American concern to scientists around the world for $85 a sample," according to the article. "They want the practice stopped, and are demanding compensation for what they describe as the violation of their personal integrity."
