A popular podcast called The Telepathy Tapes claims that telepathy is real — and tons of people are convinced. So we open our minds to the possibility of mind-reading and ask: Could this be real?? And if not — what might be going on here? We dive into the science (yes — there is science!) with Dr. Katharine Beals, Prof. Jim Todd, and Prof. Chris French.

The battle over whether we should be putting fluoride in our water has reached fever pitch. We’ve got U.S. Health Secretary Robert F. Kennedy Jr. and anti-fluoride activists saying it’s a neurotoxin that’s lowering our IQs. But supporters say that fluoride is a safe and effective way to protect our teeth from cavities, and that stopping water fluoridation would lead to a spike in tooth decay. To find out who’s right, we talk to epidemiologist Dr. Ashley Malin and community health scientist Professor Lindsay McLaren.

To start off the new season we’re getting into the science of one of the most controversial and taboo sex topics around. Squirting! For some people, it’s a major sex goal — but for others, it’s a source of major embarrassment. And it turns out that people have been writing or talking about squirting and female ejaculation for CENTURIES. So in this episode, we’re going to find out: what IS squirting (like, what is this fluid??), how common is it, and if you want to start doing it … how can you? We’ll hear from Sex Educator and World Record Holder, Lola Jean. As well as Professor Caroline Pukall, Dr. Nan Wise, Professor Helen O’Connell, and Dr. Samuel Salama. 

UPDATE, April 4, 2025: An earlier version of this episode mistakenly said that usually a person cannot pee with an erect penis. While it can be difficult, it is possible (as anyone who's had a morning glory will know!). The episode has been updated.

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.

[VIDEO available on Spotify.] Imagine a vagina. You might be thinking of a passive tube, patiently waiting for a penis to shoot out sperm — and you wouldn't be alone. From Aristotle to Darwin, tons of prominent nerds classified males as the active sexual players: They're coercing, manipulating and harassing to reproduce, while the females are passive, coy, chaste. But animal ecologist Dr. Tiana Pirtle is here to give us the real story.

Because once scientists started investigating what really goes on in the vaginas of the animal queendom, they realized that — far from being docile tubes — vaginas are packed with their own weaponry, tools and secret chambers. It turns out that both penises and vaginas were allowed to fight in the evolutionary arms race. Pirtle breaks open a box filled with animal vaginas to tell us all about it.
