Researchers test her fear response using some very unconventional methods, but she takes everything in stride. Then, finally, they stumble onto the one thing that makes the woman who can’t feel fear absolutely panic. We scare up some science with neuropsychologist Dr. Justin Feinstein.

Vaping: Does It Really Cause Cancer?
23/04/2026 Duration: 42minHeadlines have been screaming about a new study suggesting that vaping could cause cancer — and that vaping could be just as dangerous as cigarettes. And if this were true, it would be a HUGE deal. We’ve been hearing for years that vaping is a safer option — and can help you quit ciggies. But the new paper has run up against angry criticisms from other scientists, with some calling the paper "misleading" and "problematic." So what’s going on?? Do scientists still think vaping is safer than cigarettes? How well do vapes actually help people quit smoking? And could Big Tobacco be behind the scenes, clouding the truth about all of this??
