The Search for Mediators of Aging

In 1988, researchers showed that they could extend the lifespan of worms by manipulating the genetics of these model organisms. The implications that the normal aging process could be altered ignited scientific research into the emerging area of geroscience. As the Buck Institute for Research on Aging readies to mark the anniversary of this landmark research with a day-long celebration, we spoke to Gordon Lithgow, chief academic officer of the Buck. Lithgow discussed how the field has advanced from that key discovery, our understanding of aging today, and what progress has been made to identify compounds that could extend healthy years of life.
