Science Vs

The internet tells us that narcissists are everywhere — and that the problem is only getting worse. It’s like narcissism is oozing out of our celebrities, politicians, partners, parents, maybe even ourselves?? So today, we’re taking a long look in the mirror to find out: are we all a bunch of narcissists? And what should we do if we think someone in our life is a narcissist? We find out by talking to a real narcissist, Lee Hammock of the social media platform “The Self Aware Narcissist” as well as psychologists Prof. W. Keith Campbell, Prof. Kali Trzesniewski, and Dr. Craig Malkin.

A group of scientists meet a very unusual woman. A key part of her brain isn’t working: the amygdala. This is the part of the brain that we think is responsible for feeling fear. And in fact, this woman does seem pretty fearless. 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.

A weird virus has popped up on a cruise ship, and it’s making a bunch of us nervous. It’s a type of hantavirus called Andes virus, and scientists think that it’s infected almost a dozen people so far — three of them have died.

Headlines 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?? We get help sorting it out from Professor Bernard Stewart, Professor Lion Shahab and Professor Becky Freeman.

Lots of us love — or love to hate — running. And we do it because it’s supposed to be healthy, right?! But then we hear tons of stories about runners getting hurt — sometimes so badly that they have to hang up their sneakers. And there are people on social media going even further, claiming it’s one of the worst things we can do for our bodies. So IS running secretly bad for us? And could too much of it actually bring you closer to a heart attack? We’ll explore the science on all of that, and we’ll also dig into runner’s high: What is going on in the brain to cause this feeling?

We’ve all been there. Feeling stuck with a problem because no one in our life can relate. Or because the one person we need to talk to … won’t. Or can’t. Enter Yowei Shaw and the show Proxy. Proxy is built on a simple idea: no one is ever as alone with their problem as they think. So Yowei brings in a proxy, a perfect stranger, to help her guests work through their dilemma. Today we’re sharing the case of Brian, a journalist whose mother-in-law has Alzheimer's. Even though Brian knows she can’t help misremembering things, he can’t stop losing his patience with her, and with himself. This episode was mixed for Science Vs by Bobby Lord. – Find Proxy here.

Federal agents have descended on Minneapolis in the U.S., and things have gotten chaotic — and deadly. The Trump administration says the agents are there to enforce immigration law, but officers have shot three people so far, killing two, and are using tear gas and smoke on protesters. So today, we’re looking at the potential health impacts of tear gas. We’ll talk about what we do — and don’t — know about potential long-term effects of this stuff. And we’re also looking into research on the mental health effects of immigration raids. We speak to Dr. Jennifer Brown, Dr. Carlee Toddes, and Dr. William Lopez.
