Neandertals that made art, live news from the AAAS Annual Meeting, and the emotional experience of being a scientist

We talk about the techniques of painting sleuths, how to combat alternative facts or “fake news,” and using audio signposts to keep birds from flying into buildings. For this segment, David Grimm—online news editor for Science—talks with host Sarah Crespi as part of a live podcast event from the AAAS Annual Meeting in Austin. Sarah also interviews Science News Editor Tim Appenzeller about Neandertal art. The unexpected age of some European cave paintings is causing experts to rethink the mental capabilities of our extinct cousins. For the monthly books segment, Jen Golbeck interviews with William Glassley about his book, A Wilder Time: Notes from a Geologist at the Edge of the Greenland Ice. Listen to previous podcasts.
