A MODEL FOR LIFE
Elizabeth Blackburn knows that loose ends contribute to aging and many of its associated diseases. She, together with Carol Greider and Jack Szostak, received the 2009 Nobel Prize in Physiology or Medicine for their work on the synthesis and function of telomeres, the unusual DNA sequences at the ends of chromosomes. Telomere changes are now recognized in human diseases ranging from cancer and cardiovascular disease to depression. Here, she discusses her approach to mentorship, how scientists might inform public policy, and new directions in telomere research.
