Featured interview: Vow CSO James Ryall

How would you feel about eating woolly mammoth meat? Seriously. Vow, an Australian cultured meat startup, is on a mission to mix and match cells from unconventional species to create an entirely new kind of meat -- all without slaughtering animals. Their team made a mammoth meatball by injecting mammoth DNA into the muscles of a sheep and then filling in a few gaps with an African elephant's DNA, the mammoth's closest, non-extinct relative. Joining Julia to discuss is Vow Chief Scientific Officer James Ryall.  To learn more about how CNN protects listener privacy, visit cnn.com/privacy Learn more about your ad choices.
