A few years ago, my wife read Rebecca Skloot’s “The Immortal Life of Henrietta Lacks,” and shared with me the story of this woman who died of cervical cancer in 1951.

There was a new development in her story last week when the family met with top scientists at the National Institutes of Health to come to an agreement about how those “HeLa” cells can be used, and by whom. To understand all the details of this story, I asked bioethicist Art Caplan to explain it on my America Weekend show.
