(PhysOrg.com) -- A recent study of centenarians (reported in PhysOrg on July 1st) that linked a number of gene variants to longevity has now been questioned by other scientists, who suggest a DNA chip known as 610-Quad, used in the analysis, has a tendency to produce false-positives. The flaw in the chip, along with other concerns, has cast doubts on some of the major findings of the study.
