Research in North Carolina is raising ethical questions

Season 2016 Episode 1400 | 10m 03s

More than 12,000 residents from a former textile mill town in North Carolina are donating their blood and urine samples to a research campus. Scientists hope to use these specimens to find cures for diseases. But there are ethical concerns around what donors have given away and what, if anything, they will get back in return.Special Correspondent John Larson visited Kannapolis to find out more.
