CBS News explores the "controversial practice of patenting human genes," and warns that it can possibly have adverse effects on the development of health care, as researchers do not share scientific knowledge anymore. The report tells the stories of two homosexuals who felt like "walking miracles" because their AIDS tests continued to come up negative. They offered themselves for research and contributed to a genetic discovery that explained their immunity. Now Steve Crohn and Eric Fuchs insist on becoming co-owners of the rare gene that has been patented by the research organization, CBS reports. The segment extensively quotes Lori Andrews, adviser to Congress on biotech issues, whose point is that "greed has become a cultural value in health care."
