Today, we have an interview with molecular ecologist and population biologist Bridgett vonHoldt, assistant professor in Ecology and Evolutionary Biology at Princeton University. Professor vonHoldt's research centers around using the concept of epigenetics to understand evolutionary change. Specifically, she researches the epigenetics of canids — these are canines like our beloved dogs and the Yellowstone wolf — and the evolutionary biology of the domestication of dogs. Then, Brian informs us how cell phone towers work. After that, Ingrid Ockert tells us about "Science in Wonder Land: The scientific fairy tales of Victorian Britain," by Melanie Keene. (10/4/16)
