Today, best-selling author and nerd Mary Roach joins us to talk all about sex. We’ll uncover the secrets of the female orgasm (does “upsuck” exist?), detail the bizarre methods of pioneering sex researchers like Masters and Johnson (including a famous penis camera), and get into the nitty-gritty of how to sexually stimulate a pig in Denmark. Plus, Mary tells us what it's like to have sex while getting an ultrasound — all in the name of science.

Mary’s new book, Replaceable You: Adventures in Human Anatomy, is out now.

Colorectal cancer has long been thought of as a disease of older folks. But that's changing — fast. Rates in older people are actually going down, and more and more people under 50 are getting this disease. And a surprising number of them are dying from it. So what’s going on here? We dig into why young people are getting hit harder. Plus, we often hear that you should watch out for changes in your poo. But what changes?? We’ll find out. We talk to gastrointestinal medical oncologist Dr. Michael Foote and cancer biologist Prof. Ludmil Alexandrov.

People are reporting a very strange phenomenon: They say that when their nipples get touched, they feel this weird sinking feeling. People describe it like being homesick, or hung over. Some feel anguish and despair, others call it dread. The condition has a name: "Sad Nipple Syndrome." But how could just touching a nipple set off all of these feelings?? To get to the bottom of this booby baffler, we go deep into the mysteries of anatomy and through a world of hormones and nipple erections. You might never look at your nipples the same way again!

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.

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.

This episode does mention mental health issues. Find resources here: spotify.com/resources

So — are we outsourcing too much of our thinking to the bots?? Will our brains turn to mush? Or can we use AI to boost our brainpower? To find out, we talk to Dr. Shiri Melumad, expert in the psychology of technology, and Dr. Aaron French, expert in information systems.
