The Molecular Fingerprint of Death Is Written in Your Genes — And It Looks the Same in Mice, Monkeys, and You (opens in new tab)

Scientists have long suspected that aging, at its molecular core, follows a conserved script — that a mouse dying of old age and a human doing the same are, in some fundamental sense, running the same program. A landmark study published in Nature now provides the most comprehensive evidence yet that this is true, and offers a toolkit to read and score that program in real time from a blood sample or tissue biopsy. Researchers at Harvard Medical School’s Brigham and Women’s Hospital, led by Va...
