Science Friday
Fridays 1 - 3 p.m.
Science Friday is a weekly science talk show, broadcast live over public radio stations nationwide. Each week, we focus on science topics that are in the news and try to bring an educated, balanced discussion to the scientific issues at hand. Panels of expert guests join Science Friday's host, Ira Flatow, a veteran science journalist, to discuss science -- and to take questions from listeners.
To participate, call 1 (844) 724-8255 or Twitter users can tweet questions @scifri.
