When a critter meets its end at the Smithsonian’s National Zoo, it ends up on a necropsy table—where one of the zoo’s veterinary pathologists will take a very close look at it, in what is the animal version of an autopsy. They’ll poke and prod, searching for clues about the animal’s health. What they do—or don’t—find can be used to improve the care of living animals, both in the zoo and in the wild.On stage in Washington, D.C., Ira talks with Dr. Kali Holder, veterinary pathologist at the Smithsonian’s National Zoo and Conservation Biology Institute, about her work, and they embark on a case of CSI: Zoo.Transcripts for each segment will be available the week after the show airs on sciencefriday.com.
