Biobanks hold human blood, urine and tissue samples that researchers use to analyze DNA in order to form new diagnostic tests and personalized medicines. But the business raises ethical, privacy and payment questions. These concerns are playing out in one North Carolina town, where more than 10-thousand residents have donated their DNA to a research institute deigned with the ambition of changing modern medical treatment and prolonging human life.
