Animals that don’t need people to be domesticated; the astonishing spread of false news; and links between gender, sexual orientation, and speech

Animals that don’t need people to be domesticated; the astonishing spread of false news; and links between gender, sexual orientation, and speech

Did people domesticate animals? Or did they domesticate themselves? Online News Editor David Grimm talks with Sarah Crespi about a recent study that looked at self-domesticating mice. If they could go it alone, could cats or dogs have done the same in the distant past? Next, Sinan Aral of the Massachusetts Institute of Technology in Cambridge joins Sarah to discuss his work on true and false rumor cascades across all of Twitter, since its inception. He finds that false news travels further, deeper, and faster than true news, regardless of the source of the tweet, the kind of news it was, or whether bots were involved. In a bonus segment recording during a live podcasting event at the AAAS Annual Meeting in Austin, Sarah first speaks with Ben Munson of the University of Minnesota in Minneapolis about markers of gender and sexual orientation in spoken language and then Adrienne Hancock of The George Washington University in Washington, D.C., talks about using what we know about gender and communication to help transgender women change their speech and communication style. Live recordings sessions at the AAAS meeting were supported by funds from the European Commission. This week’s episode was edited by Podigy. Listen to previous podcasts.
