From the earliest grunts and gestures to the complex sentences we use today to convey a multitude of concepts, language has evolved to become one of humanity’s most powerful tools. It allows us to connect, create, conspire, control, console, catch up, and so much more. How did we come to have this uniquely human trait? What anatomical changes or cultural developments were necessary for language to evolve? What differentiates language from communication? In this TPWKY book club episode, Professor Steven Mithen joins us to discuss his latest book The Language Puzzle: Piecing Together the Six-Million-Year Story of How Words Evolved. By combining scholarship across wide-ranging fields such as archaeology, genetics, anthropology, linguistics, neuroscience, and more, Professor Mithen presents a compelling story of the origins of language. If you’ve ever wondered how babies can go from babbling one day and talking in a torrent of words the next, or how an individual language changes with each generation, this is the episode and book for you.

In last week’s episode, we traced the history of fluoridation (and the anti-fluoridation movement) to its roots in the early 20th century, but we left you wondering whether there’s anything to back up the health claims that anti-fluoridationists make. Today, we get deep into the weeds of the fluoride literature, explaining how this mineral works, the difference between topical and systemic fluoride, and whether fluoridation has been linked to any health issues. The details matter, and don’t you worry - we’ve got plenty of nitty gritty for you to feast on.

Is it just us, or does it seem like every other week there’s a new headline about some state or town banning water fluoridation? As it turns out, this has been going on for decades, basically since fluoride was first introduced. Why are some people opposed to fluoride? Is there any basis to their fears? What does fluoride actually do? And how the heck did we find out about it? This week and next, we’re deep diving into our first dental discussion about this revolutionary mineral. In the first of these episodes, we explore the origins of fluoridation and the outcry against it - how did tuberculosis, a gold rush town, and a dentist with an insatiable curiosity set the stage for one of the greatest public health achievements of the 20th century? And why has there been pushback against it since its inception? Tune in to find out.

For many of us, pelvic exams are a routine part of our healthcare. Of course, that doesn’t mean we don’t await them with some dread or anxiety; naturally, these exams evoke a wide range of emotions. But they are a cornerstone in gynecological preventative care - a relatively new one at that. In this TPWKY book club episode, we sit down with Dr. Wendy Kline, Historian of Medicine at Purdue University, to discuss her book Exposed: The Hidden History of the Pelvic Exam. Dr. Kline takes readers through various chapters in the story of this exam: its murky origins at the hands of J. Marion Sims, its stint as a psychological diagnostic tool used by some misogynistic doctors, and its reclamation by feminist physicians and activists who sought to connect with their own bodies. Tune in for a fascinating conversation that exposes all sides of the pelvic exam, with heroes, villains, and more.

If you’ve ever read the little instructions pamphlet included in a box of tampons, you probably came across a paragraph calling attention to a condition called toxic shock syndrome (TSS). It describes the association between TSS and tampon use, symptoms of TSS, and guidance on how to reduce risk. This legally mandated warning label has formed an indelible link connecting tampons and TSS, and indeed, tampons form a large part of the story of TSS. But they are not the entire story. In this episode, we delve into that full story, examining what TSS actually is, the pathogens it’s associated with, and how it was first identified. If you’ve had TSS questions ever since you first heard of it in health class or on your box of tampons, this is the episode for you!

This week, we’re coming at you with a classic TPWKY episode on one of the most notorious poisons out there: strychnine. Although strychnine might not flash across too many headlines these days, it was once imported by the ton in certain regions of the world. What did people want with so much strychnine? Depends on who you ask. Maybe it was for a revitalizing tonic, maybe a rat poison, or maybe it was to murder the founder of a famous university. Tune in to learn how this deadly poison acts on the body and keep listening for a very special musical treat.  Support this podcast by shopping our latest sponsor deals and promotions at this link: https://bit.ly/3WwtIAu See omnystudio.com/listener for privacy information.

For the past few months, measles has been in regular rotation in the news cycle here in the US, with outbreaks occurring across the country in regions with low vaccine uptake. These outbreaks represent a worrying trend in the rejection of scientific and medical expertise, with long-term consequences not only for those individuals refusing vaccines but also the communities to which they belong. In this TPWKY book club episode (recorded March 14, 2025), Dr. Adam Ratner joins us to discuss his book Booster Shots: The Urgent Lessons of Measles and the Uncertain Future of Children's Health. With his firsthand experience treating children with measles and other vaccine-preventable diseases, Dr. Ratner provides a powerful perspective on the dangers of the measles virus and vaccine hesitancy. What can we learn from the history of measles and the measles vaccine rollout? Why is measles such a dangerous virus? Where do we go from here? Tune in for all this and more.

Last week, we started this two-parter with a big picture view of pasteurization and the raw milk movement. In this episode, we address the alleged health claims made by proponents of raw milk and dive into the very real risks carried by its consumption. Is raw milk actually better for you? Does it have more vitamins or prevent allergies? What deadly pathogens does it harbor? How much does drinking raw milk increase your chance of contracting a milk-related disease? (Spoilers: A LOT). We tackle these questions with reliable data that paint a very different picture of raw milk than that shown by many raw milk influencers. Tune in for all this and more.

Seriously, what’s the deal? Lately, it seems like raw milk has started to pop up more and more frequently in our feeds, with influencers touting the alleged health benefits of raw milk over pasteurized milk. In this and next week’s episode, we explore the raw milk phenomenon as it has grown over the past few decades. We start this two-parter with a look at the dangers of milk in a pre-pasteurization world, how Pasteur developed the life-saving process that bears his name, the subsequent rise of anti-pasteurizers, and how the anti-science sentiment surrounding raw milk today reveals a larger and more troubling agenda.

Tuberculosis, or consumption as it was once known, might conjure up images of huge sanitoriums or writers and artists from the late 1800s (Moulin Rouge, anyone?). But this deadly disease is far from an illness of the past. In many parts of the world, tuberculosis remains an insidious killer, despite the fact that we’ve had effective drugs to treat the infection for decades. In this week’s TPWKY book club episode, we’re thrilled to be joined by the one-and-only John Green to chat about his latest book, Everything Is Tuberculosis. Tune in for a fascinating conversation that tours the past, present, and uncertain future of this devastating illness.

We’re already back with our first episode of season 8! This week and next, we’re exploring childhood vaccine schedules - what diseases they protect us from, how the schedule is arranged, and who decides on the vaccines to include and the timing of vaccinations. In this first episode, we start with a refresher on how vaccines work before running through the entire schedule we have here in the US, vaccine by vaccine, comparing pre- and post-vaccine mortality rates. We close out the episode by discussing why vaccination is so important, not just for personal protection but for our communities. Stay tuned for more childhood vaccine schedule talk next week!

In Act 3 of our pregnancy series, we arrive at the big moment: childbirth. We begin the episode with a closer look at one of the most commonly performed surgeries around the world: the cesarean section. Exploring how this procedure went from rare to everywhere reveals some of the larger medical trends shaping the childbirth experience in nuanced ways. Then, we take a step back to ask “what is actually happening in labor?” Journeying through the labor and delivery process contraction by contraction gives us the opportunity to examine what is happening in our bodies during this crucial time and how things might not go according to plan.

The second episode in our pregnancy series kicks off with a tribute to one of the most amazing organs: the placenta. We trace the evolutionary origins of the human placenta and examine how this organ allows for such an intimate and delicately balanced relationship between mother and fetus, as well as what can happen if that balance is disrupted. We then turn towards the pregnant person, exploring the broad physiological changes that happen body system by body system throughout pregnancy. Why do you pee so much? Feel nauseous? Have high blood pressure? We get into it all.

With this and the next three episodes, we’re delivering a four-part series on pregnancy, trimester by trimester. We start our series with a tour through the history of the pregnancy test: how and when did these sticks with the two blue lines become the everyday at-home medical device they are today? How has their introduction changed the knowledge that women have about their bodies and who has access to that knowledge? Then we explore the biology of what happens at the very beginning of pregnancy with some light embryology, exploring the earliest steps of implantation, placentation, and what could happen if this process doesn’t go as expected.

For much of history, female reproductive anatomy has been studied only in the context of or in comparison to male reproductive anatomy. This shows in clinical trial design, in healthcare disparities, in the research questions we ask (or fail to ask), it’s even apparent in our language - the word “vagina” means “sheath”, as if vaginas only exist to sheathe penises. Only recently have researchers begun to close this gap in our knowledge when it comes to half the humans on this planet. In Vagina Obscura: An Anatomical Voyage, award-winning journalist and author Rachel Gross takes readers through the origins of this information gap, examining how preconceived notions about sex and gender underlie the bias that still exists today. She then delves into the fascinating research that seeks to confront this bias and address the vast health inequities that limit care for so many. Tune in for a truly enlightening odyssey through the only recently charted world of female anatomy.

Has a name brand prescription medication ever shot to notoriety as quickly as Viagra did? Within a few months of its arrival on the market, it seems like everyone knew about the little blue pill, whether through commercials featuring celebrity spokespeople or from endless jokes on late night talk shows. But while everyone understood that this medication promised to treat erectile dysfunction, what most people didn’t know was the wild story leading to its development. Or how this medication (and similar medications) actually works. Or the tremendous impact this blockbuster drug would have on the ways that medications are advertised and developed. In this episode, we bring you those stories (and many more).

In forests, in lawns, in city parks across the world lurks a small, pale, unassuming mushroom whose inconspicuous appearance belies its deadly nature. For within this mushroom dwelsl one of the deadliest poisons known to humans: amatoxin. It’s because of this toxin that the aptly-named ‘death cap mushroom’ (Amanita phalloides) is responsible for the vast majority of mushroom-related deaths around the globe each year. What makes this poisonous mushroom so very deadly, and is there anything we can do about it? In this episode, we take a journey through this legendary mushroom’s story, exploring its destructive biology, its murderous history, and its worrying yet hopeful future.

Okay everyone, think about your tongue. Maybe move it around a bit, check in with it, consider what it means to you. Now imagine that your tongue suddenly shriveled up and fell off and that in its place is a tongue-sized isopod aka rollie pollie aka pillbug. Just there, hanging out, forever. How are you feeling? Horrified? Disgusted? Hey, we get it. But at least you’ll never be alone again. Believe it or not, this is not some bad creative writing exercise. This is a very real parasite. In fact, it’s not just one but a whole group of them. Fortunately for us humans, these tongue-replacing isopods don’t target mammals but rather various fish species (unfortunately for the fish). And in this week’s episode, we’re getting up close and personal with these bizarre (and dare we say cute?) organ-replacing parasites. If you’re wondering why on earth you should care about a niche parasite like this one or why it might be a bad idea to get rid of all of earth’s parasites, then we warmly invite you to sit back, relax, and enjoy this parasite appreciation hour.
