Weird Science: CBS's Kaledin Implies 'Embryo' Mice Are Not 'Live' Mice

On the August 7 CBS Evening News, while filing a story about stem cell research on mice aimed at some day treating deafness in humans, correspondent Elizabeth Kaledin curiously implied that mouse embryos are not living, perhaps betraying a bias in how she views embryos in general. As she described research by Stanford University scientist Dr. Stefan Heller in which he injects stem cells into the ears of "mouse embryos," Kaledin informed viewers he plans to later try injecting stem cells into fully developed mice, which she referred to as "live mice," as if embryos were not technically alive. Kaledin: "He and his colleagues have figured out how to inject stem cells into the ears of mouse embryos and watch them grow. Their next step is to try it in live mice."
