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.

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.

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.

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.

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.

We are coming at you with our very first live episode from Perth, Australia! Here at the 2024 Australian Institute of Occupational Hygienists Annual Scientific Conference and Exhibition, occupational hazards and exposures get top billing. And one of the most ubiquitous hazards, experienced by nearly every industry is fatigue, specifically fatigue caused by circadian rhythm disruption. In this very special episode, we explore how our circadian rhythms work and some of the consequences that can emerge when we work against those rhythms, whether that’s because we’re traveling across many time zones or switching to night shift work. We then dig into the history of circadian rhythm research, from how we first learned about these daily patterns to when their disruption became a routine occurrence. Helping us to navigate some of the alarmist headlines (“your screens are ruining your sleep!”) and biohacker claims (“avoid jet lag with this one simple trick!”) is Ian Dunican, PhD. Dr. Dunican is the Director and Chief Adviser of Melius Consulting, a scientific consultancy undertaking research, consulting, and education, and he also hosts and produces the Sleep4Performance podcast. We also bring on Dr. John Iliff, Emergency Physician and Aeromedical Consultant to share his frightening experience with fatigue after a long shift during his training as a physician.

Everyone’s got a favorite disease movie. What’s yours? Does it feature zombies like 28 Days Later (2002), or is it more grounded in reality, like Contagion (2011)? Does it end with a glimmer of hope or with a dose of despair? Who are the bad guys and who are the good guys? From the early days of disease movies like Panic in the Streets (1950) to more recent films like Little Joe (2019), these movies have provided endless entertainment, excitement, and opportunities to examine society itself. In this TPWKY book club episode, Robert Alpert, Dr. Merle Eisenberg, and Dr. Lee Mordechai join us to discuss their book Diseased Cinema: Plagues, Pandemics, and Zombies in American Movies. Diseased Cinema approaches the genre of disease-themed movies with the goal of understanding what these movies say about our hopes, our fears, our anxieties, and how these perspectives have shifted over the decades. When did faith in our government’s problem solving give way to rugged self-reliance? Why did people start to view science as the bad guy rather than the source of salvation?

For decades, it seemed like the appendix would go the way of 8-track players, pagers, and the phonograph. Outdated, obsolete, not worth keeping around. Surgeons performed appendectomies like it was spring cleaning - when in doubt, cut it out. But then the tides began to turn as medicine started to question the long-held belief that the appendix is a defunct organ (on a good day) or a ticking time bomb (on a very bad one).

Among the many conditions that creep under your skin and make scratching irresistible, scabies alone holds the honor of being called simply “The Itch” for centuries. In this episode, we examine how the burrowing scabies mites cause this extremely uncomfortable sensation, what we can do to halt their progress, and how contagious they really are (less than you probably think). Today, the word scabies instantly conjures up images of the mite responsible for The Itch, but for centuries, medicine failed to make that connection, even when the proof was right in front of them and when traditional wisdom had long since known mite=scabies.

A mere 150 years ago, uttering the words “scarlet fever” was enough to strike fear into the hearts of many, especially parents of young children. For a brief period of time, this disease, caused by an infection with the bacterium Streptococcus pyogenes, reigned as a leading cause of childhood death in many parts of the world. It left its mark on gravestones, in public health decrees, in literature like the Velveteen Rabbit, but then something changed. The disease became milder, no longer the deadly threat it once was. But it didn’t go away entirely or lose its bite completely. In this episode, we examine the biology of scarlet fever and trace how it can make you sick before exploring its strange and tragic history.

We really don’t give fungi the credit they deserve. Over the years of this podcast, we’ve covered only a handful of fungal pathogens, and pathogenic fungi themselves represent a teeny tiny proportion of the incredible diversity of fungal life on this planet. But with this book club episode, we’re attempting to correct this oversight, at least a little bit. Toxicologist and science writer Dr. Emily Monosson joins us to discuss her book Blight: Fungi and the Coming Pandemic. We chat about how fungal epidemics have shaped entire ecosystems, altered economies, and invaded hospitals. Despite the devastating impact pathogenic fungi have made, we still underappreciate their potential to cause harm in the future, as our climate changes, as our land use changes, and as globalization continues. In Blight, Monosson delivers an important reminder that we should use what we have learned about these historical outbreaks to limit the harm fungi may cause in the future.

That little bottle of retinol serum sitting on your bathroom counter - what do you know about its history? This week, we’re digging deep into the man behind the medicine, renowned dermatologist Dr. Albert Kligman, and the unethical research he conducted at Holmesburg Prison in the mid-20th century. Kligman’s research program at Holmesburg spanned decades, involved dozens of experiments (including tretinoin) and thousands of individuals, received ample funding from public universities and many pharmaceutical companies, and was generally praised until it all came crashing down in the early 1970s. But, as we’ll discover, the unethical behavior persisted even after the program’s closure as Kligman fought to get tretinoin to market. The murky history of retinoids might be a bit too long to include on the label, but this episode forces us to consider the human cost of a household product and the importance of acknowledging that history.

In this TPWKY book club episode, Pulitzer Prize-winning journalist Kate Zernike joins us to discuss her book The Exceptions: Nancy Hopkins, MIT, and the Fight for Women in Science, which details the sequence of events that led sixteen scientists to demand the equality that had been denied to them for so long. Zernike, who was one of the reporters to break the story in 1999, centers this story on molecular biologist Dr. Nancy Hopkins, who, armed with a tape measure, brought this history of marginalization to light. Simultaneously personal and panoramic, The Exceptions carefully illustrates the sexism entrenched in higher education and academia and sends an important message: this problem is far from solved.

Stiff person syndrome, like many rare diseases, does not get nearly the same amount of screen time or name recognition that other, more common diseases do. For many people, Celine Dion’s announcement of her diagnosis with the condition in 2022 marked the first time they had heard of it. This limited awareness surrounding stiff person syndrome marks just one of the many challenges keeping this disease and other rare disorders in the dark. In this episode, we attempt to shed some light on stiff person syndrome, exploring the complex biology, frustrating history, and hopeful future of this disease. Because while the field of stiff person syndrome research faces many hurdles, there are also so many individuals - researchers, patients, advocates - and organizations that fight to bring this and other rare disorders into the light.

Five years ago, we asked you all to ask us anything, and you delivered. We answered dozens of listener questions, like how we first met, our favorite quarantinis, where we were in our career journeys, and so many more. But in the years since that first “ask us anything”, a lot has changed for both of us! So we’re coming back to you with the answers to more of your probing questions, like “what disease names would make good person names?”, “where are you in the world these days?”, “if you could have only one sandwich for the rest of your life, what would it be?” and a million more, ranging from serious to silly and everywhere in between.

How is it that we can’t remember where we put our keys or the name of the person we just met, but we can recall in excruciating detail the embarrassing interaction we had at the grocery store ten years ago? Sometimes it seems like our memory works against us more than it does for us. But, as it turns out, this aspect of our memory is more a feature than a bug, and the key to understanding the difference may lie in our evolutionary history. Dr. Charan Ranganath, Professor of Psychology and Neuroscience and Director of the Dynamic Memory Lab at the University of California at Davis, joins us today to discuss his book Why We Remember: Unlocking Memory's Power to Hold on to What Matters. Dr. Ranganath deftly guides readers through not only the “how” of memory formation but also the “why”, helping us to understand why we remember certain things and forget others. Tune in for a fascinating discussion ranging from the importance of context (like smell) in memory to the different types of memory, from decision-making to memory competitions, and so much more!

One day, you’re enjoying a beautiful hike through the tall grass. A few months later, you find yourself in anaphylaxis from a post-hike hamburger. The culprit: a tick bite. In this much-requested episode, we take on alpha-gal syndrome, the red meat allergy triggered by the bite of a tick. Sometimes science is stranger than fiction. How exactly does an encounter with a tiny arachnid cause your throat to swell up and your skin break out into hives hours after eating red meat? Is it all red meat? Is it all ticks? How on earth did anyone even make this connection in the first place? Those are just a few of the questions we answer in this action-packed episode that has us venturing into surprising topics, like primate evolution, ancient epidemics, and cancer treatments.

For life on this planet, iron is not optional. It is essential. When our iron levels are low, we can get sick, and when they get really really low, we can even die. But you know what they say, too much of a good thing can be a bad thing. In the case of iron, the genetic condition hemochromatosis is often to blame for iron overload, but why is too much iron a bad thing? In this episode, we explore that question and many others, starting with why iron is a biological non-negotiable and how a lack of iron regulation in hemochromatosis can lead to severe tissue damage. Then we’re going Deep Time™ to suss out the origins of our dependence on iron, a journey that eventually leads us to the Neolithic Revolution and the 20th century realization that a certain ancient medical practice is not as obsolete as previously thought.

Phosphorus is an element that wears many faces. Its overuse as a fertilizer has polluted freshwater ecosystems, transforming rivers and lakes from thriving communities to lethal zones devoid of life. Its role as an explosive has brought fiery death and suffering to many during times of war. And its dwindling global supply poses an existential threat to humanity. Because phosphorus is not just a destructive force - it is essential for all of life on this planet. In The Devil’s Element: Phosphorus and a World Out of Balance, author Dan Egan explores the multi-faceted nature of phosphorus and the surprising ways this element has shaped our world. Egan, Journalist in Residence at the Center for Water Policy in the University of Wisconsin-Milwaukee's School of Freshwater Sciences, transports readers from the guano-covered islands off the coast of Peru to the fertile fields of the American Midwest, from the 17th century laboratories reeking of boiled urine to our tenuous future as the demand for this element outpaces its supply.

“Is it gonna be poop or is it gonna be barf?” It’s the question we all fear during a bout of food poisoning when time is of the essence and a decision has to be made before it’s made for us. Often, the germ forcing this question upon us is none other than the dreaded norovirus. First called “winter vomiting disease” for reasons obvious to anyone who has been unfortunate enough to become infected, norovirus now conjures up images of puking passengers aboard cruise ships or oysters on the half shell secretly harboring a vomiting virus. In this episode, we delve into the world of norovirus, examining what qualities make it spread so rapidly and sicken us so quickly. Our tour of norovirus history takes us down some surprising roads, where we meet Vomiting Larry and chat about vulture vomit. We round out the episode by looking at norovirus by the numbers, dispelling the notion that norovirus can only be found aboard cruise ships. Spoilers: it’s everywhere.

In the pre-antibiotic era, tuberculosis was one of the biggest killers humanity ever faced. The specter of the ‘great white plague’ hung over towns and cities across the world, cities like New York whose population boom in the early 20th century paved the way for this deadly disease to spread throughout crowded tenements. As tuberculosis rates in NYC reached a breaking point, city officials sought to solve the problem by establishing a sanatorium on Staten Island. But they quickly ran into an issue - who would be willing to work there, exposing themselves to this untreatable deadly disease? In The Black Angels: The Untold Story of the Nurses Who Helped Cure Tuberculosis, author Maria Smilios tells the story of the courageous nurses who worked at Sea View Hospital on Staten Island, facing the constant threat of disease and perpetual racism from patients, colleagues, and neighbors. Smilios brings these women’s stories to life, describing how they persevered in these difficult conditions to ultimately help bring about the cure for tuberculosis, for which they have only recently been recognized.

Roads are essential to our modern lives, so much so that they largely exist in the background of our minds. When we do think of roads, we’re either complaining about traffic or celebrating them for enabling our restless need to explore. Can you imagine if all of the world’s 40 million miles of roads were suddenly erased? Chaos for humanity. But a boon perhaps to natural ecosystems. In Crossings: How Road Ecology is Shaping the Future of Our Planet, author Ben Goldfarb takes readers on a fascinating tour of the relatively recent science of road ecology. Even beyond their impact on roadkill, roads are powerful disruptors of natural ecosystems, bringing noise, pollution, and humans to natural areas and fragmenting landscapes. And as Goldfarb demonstrates, we are only just starting to reckon with the widespread effects of roads and integrate this knowledge into road design. After this fascinating conversation, you’ll never think of roads in the same way again! Learn more about your ad choices. Visit megaphone.fm/adchoices

Think of an infectious disease. What comes to mind? A viral infection like influenza? Or a bacterial illness like cholera? Maybe some of you thought of a fungal pathogen or a parasite. But how many of you thought of a cancer? In this episode, we explore the bizarre, stranger than fiction story of devil facial tumor disease (DFTD), a transmissible cancer that has devastated Tasmanian devil populations over the past few decades. And when we say transmissible cancer, we don’t mean a cancer caused by a virus - we mean the cancer itself is transmissible. How is that possible? What does it do to the devils? What are Tasmanian devils like? What role do they play in the ecosystem? What does the future hold for these adorable creatures? Tune in for a lively discussion all about these devils and their disease, featuring Dr. Rodrigo Hamede, Senior Lecturer at the University of Tasmania and DFTD expert. This episode will have you looking up pictures of baby devils, listening to their wide range of sounds, and rethinking the lines between contagious and non-contagious disease.

CW: discussion of disordered eating, eating disorders Did the word gluten manifest in everyone’s consciousness one day in 2010? Suddenly, grocery stores were filled with gluten-free crackers, cookies, buns, you name it. Everyone went on gluten-free diets or knew someone with a gluten intolerance or sensitivity. For some, it might seem that gluten-related disorders went from 0 to 60 overnight, but those who had lived with these illnesses for decades knew better. In this episode, we delve into the story of gluten intolerance and celiac disease, a story which begins thousands of years ago, not just in the 2010s. We break down why gluten makes some people sick, how scientists finally made the link between grain and pain, and what promising new research is on the horizon for treating gluten-related disorders.

Going to the doctor is probably not at the top of anyone’s list of enjoyable activities, but when we do go, we expect and deserve to be heard, to have our concerns listened to and our questions answered. However, most, if not all, of us have at some point felt unheard, dismissed, or even gaslit by our healthcare provider. What is it about the doctor-patient relationship or the way medicine is practiced today that enables this miscommunication or mistreatment, and how can we make things better? In Unheard: The Medical Practice of Silencing, author Dr. Rageshri Dhairyawan draws upon her experience on both sides of the patient-physician relationship to explore these questions in depth. Dr. Dhairyawan, who is a sexual health and HIV doctor with the NHS as well as a health equity researcher and science communicator, demonstrates with clarity and compassion how each dimension of healthcare, from training to research and beyond, can contribute to this pattern of patients going unheard.
