Wild polio has been hunted to near extinction in a decades-old global eradication program. Now, a vaccine-derived outbreak in the Democratic Republic of the Congo (DRC) is threatening to seriously extend the polio eradication endgame. Deputy News Editor Leslie Roberts joins host Sarah Crespi to talk about the tough choices experts face in the fight against this disease in the DRC.

 

Sarah also talks with Online News Editor David Grimm about when dogs first came to the Americas[linkTK]. New DNA and archeological evidence suggest these pups did not arise from North American wolves, but came over thousands of years after the first people did. Now that we know where they came from, the question is: Where did they go?
