Vaping: Does It Really Cause Cancer? Apr 23, 2026

Show notes

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.

Running: Will It Wreck Your Body? Apr 16, 2026

Show notes

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? With help from Dr. Rasmus Østergaard Nielsen, Professor Duck-Chul Lee, and Dr. Michael Siebers, we look at the science to find out if running is the key to a healthy life or if there are peer-reviewed reasons to be a hater.

The moon race is back! NASA’s Artemis II mission just sent four astronauts around the moon. And other countries — and billionaires — are lining up to take a crack at returning to the moon too.

Others are saying the real reason to go to the moon today is that it’ll help us get to Mars. To find out, we talk to engineer Dr. Angel Abbud-Madrid, physicist Prof. Nicolle Zellner, and astronomer Prof. Gregg Hallinan. [REBROADCAST]

How Do You Get Pregnant With No Vagina? Feb 26, 2026

Show notes

UPDATE [June 30, 2026]: If we had our time again we would have produced this episode differently. We got carried away with the wildness of the story, from a scientific perspective, and didn't take time to really think about the fact that this is the story of a 15-year-old, who would have been going through a really difficult time. Many of our listeners rightly pointed this out, and we appreciate it." We have changed some of our language in this episode based on the feedback – we replaced all references to woman to teenager or girl, we cut some moments that we viewed as insensitive, and we removed the reference to the girl not being intersex, as some folks with the condition Mayer-Rokitansky-Küster-Hauser syndrome do identify as intersex.

Here’s the story: It's 1988 in Lesotho, and doctors at a hospital see something they thought was impossible. A 15-year-old girl shows up pregnant and in labor, but she's missing something pretty crucial to her delivery: a vagina. So — how did this happen? We speak with Dr. Neel Shah to find out.

Find our transcript here: https://tinyurl.com/sciencevsnovagina

In this episode, we cover:

(00:00) A small war

(04:42) How do you get pregnant without a vagina?

(14:08) The final unbelievable chapter

This episode was produced by Ekedi Fausther-Keeys with help from Wendy Zukerman, Michelle Dang, Rose Rimler, and Meryl Horn. We’re edited by Blythe Terrell. Fact checking by Diane Kelly. Mix and sound design by Bobby Lord. Music written by Emma Munger, So Wiley, Peter Leonard, Bumi Hidaka and Bobby Lord. Thank you to all the scientists we spoke to for this episode including, Dr. Sarah Ackroyd, Dr. Sarah Collins, Professor Adam Taylor, and Dr. Cathy Flood.

Brian Can’t Stop Fact-Checking His Mother-in-Law Feb 19, 2026

Show notes

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.
