Radiolab is public radio channel WNYC’s answer to a podcast covering any topic that makes its viewers and hosts curious. The 60-minute show is hosted by Jad Abumrad and Robert Krulwich and has been on-air for 13 seasons. Season 12 traveled to different cities covering an unpublished review of extinction, inviting listeners to chime in. Any listener who tweets @radiolab has a good chance of being retweeted by the show, increasing community engagement about their scientific and philosophical topics. The 2015 year-end special was definitely a viewer favorite.
