The moderator of this panel interrupted physicist Veronika Hubeny of UC-Davis so much that audience member Marilee Talkington (appropriate name) got so frustrated that she intervened.
While watching a panel titled “Pondering the Imponderable: The Biggest Questions of Cosmology,” Marilee Talkington noticed that the moderator wasn’t giving physicist Veronika Hubeny, a professor at UC Davis and the only female on the panel, her fair share of speaking time.
So when the moderator, New Yorker contributor Jim Holt, finally asked Hubeny a question about her research in string theory and quantum gravity, then immediately began speaking over her to explain it himself, Talkington was furious.
Fed up with the continuous mansplaining, Talkington interrupted Holt by yelling loudly, “Let her speak, please!” The crowd applauded the request.

Certainly, while it is awfully annoying, based on what Dr. Hubeny described, she didn't think it was a blatant sexism. Rather, she thought that the host was just overly enthusiastic. But you may judge that for yourself if the host didn't give the only female member of the panel a chance to speak.
But yeah, good for Ms. Talkington for intervening.
