Boston University researchers have retracted a paper, originally published in Science, in which they claimed to have identified a genetic signature for human longevity, The Boston Globe reported. A new analysis found that some of the data they used were incorrect. A statement from Science said: "Although the authors remain confident about their findings, Science has concluded on the basis of peer review that a paper built on the corrected data would not meet the journal's standards for genome-wide association studies. The researchers worked exhaustively to correct the errors in the original paper and we regret the outcome of the exhaustive revision and re-review process was not more favorable."
