The U.S. Fish and Wildlife Service announced a proposal Tuesday to upgrade the status of captive chimpanzees from "threatened" to "endangered," a change which may impact the ability of biomedical researchers to utilize the species in their studies. The proposal indicates that scientists would require a permit to perform scientific research with captive chimpanzees and for the sale of chimpanzee cell lines, tissue or blood across state lines, and permits would only be available if their work involved conservation of the species. The proposal is open for public comment for the next 60 days.
