series tackles just five topics each season. Most recently, in an exploration of the science of aging and the search for immortality in an episode titled "Mortality," hosts Jad Abumrad and Robert Krulwich featured interviews with two UCSF researchers.
The show's first segment, "Life's Limit," focuses on Leonard Hayflick, PhD, adjunct professor of anatomy at UCSF, who, in 1961, discovered that human cells in a culture divide a finite amount of times before reaching a maximum limit, henceforth called the Hayflick limit. In the segment, Hayflick discusses how the introduction of telomerase can extend the life of cells beyond the Hayflick limit, but at a cost.
In "Fountains of Youth," the second segment of the program, Krulwich visits the UCSF lab of Cynthia Kenyon, PhD, where Kenyon describes a struggle--between what she dubs the "Grim Reaper" and "Fountain of Youth" genes--that influences the lifespan of the roundworm C. elegans. By tinkering with these genes, Kenyon and her team have been able to more than double the worm's lifespan. What are the implications, if any, for halting the aging process in humans?
