    Does early-life cellular activity influence cancer and aging?

    New research from Michael Lampson and Mia T. Levine in the School of Arts & Sciences offers insight into how telomeres—protective chromosomal caps linked to aging and cancer in mammals—are inherited. Their finding that telomeres become longer or shorter during early embryonic development opens new avenues for research.
