Have you ever thrown a pinch of spilled salt over your left shoulder? Or said to someone “well, take his opinion with a grain of salt”? Or looked up the potential salary of a job listing? Salt is so deeply embedded in our cultures, our languages, our history as a species that we often take its influence for granted. We may forget (or perhaps we never knew) how much history is held within the unassuming yet ubiquitous salt shaker. In the first installment of this two-parter on everyone’s favorite seasoning, we delve deep into some salt lore. When did humans start to ramp up their salt intake? Why was salt such a big deal? Which places are named for salt? When did we start worrying about how much sodium we were eating? Tune in for a fun, fact-filled episode that’ll forever change the way you think about salt.

In an anatomy and physiology class, you may learn how the different heart valves work to circulate your blood, how the structure of your kidney helps to maintain electrolyte levels, and how the expansion and contraction of your lungs sets off a carefully orchestrated cascade of gas exchange and transport. The human body is an endlessly fascinating machine. But when you spend so much time learning about the body, you can lose sight of the fact that it isn’t a machine. It is the story of your life. In this book club installment, I am joined by surgeon and award-winning writer Gabriel Weston to discuss her latest book Alive: Our Bodies and the Richness and Brevity of Existence. In this compelling blend of memoir, science, and meditation, Weston examines different body parts chapter by chapter - what they have meant to her or her loved ones, their significance in history, and how their meanings are shaped by our scientific understanding. Weston inspires readers to take a moment to reflect on what it’s like to live in your body, feel your heart beat, your lungs expand. Doing so can help us connect with ourselves and others.

If you were asked to describe necrotizing fasciitis in three words, you might choose: rapid, deadly, and rare. The third of those adjectives may provide some comfort, but the first two are the clear inspiration for this infection’s more lurid nickname: flesh-eating bacteria. In this episode, we get up close and personal with necrotizing fasciitis and its causative agents. We start off by examining step by step how these infections wreak so much havoc and why doctors still struggle with its treatment. Then we take a tour through its grisly history, featuring maritime misadventures and wicked war wounds. We wrap up the story with a look at the global trends in these infections as well as some promising new research. This episode may not be for the faint of heart, but it is for the endlessly curious.

It’s the stuff nightmares are made of. A fly lands on an open wound and lays hundreds of eggs, from which hatch countless ravenous maggots. There they writhe, devouring flesh, insatiable and relentless. Every minute they dig deeper and deeper until flesh gives way to bone. Even the species name of these maggots inspires a shiver of fear: Cochliomyia hominivorax - “man eater”. This nightmare of a fly is the horrifying reality for many mammals in South America and some Caribbean islands, particularly cattle. And it seems to be making a comeback in the places it was previously eradicated - Central and North America. What exactly this fly does, why it’s such a problem, and how we came to defeat it (temporarily) all feature in this week’s episode. Sterile flies? Archival footage? Gnarly descriptions?

Science doesn’t always get it right the first time (or the second, or the third, or even the ninety-ninth!). And while we may chuckle at the outlandish things people believed or the goofy experiments they tried, we forget two things: 1) those failures helped us get where we are today and 2) a hundred years from now, people will probably be laughing at the “cutting edge” medical knowledge of today! In this week’s book club episode, Erin and I chat with two of our all-time favorite science communicators, Dr. Lindsey Fithzarris and Adrian Teal to discuss their newest book Dead Ends!: Flukes, Flops & Failures That Sparked Medical Marvels. This hilarious and insightful book, geared towards middle-school readers (but enjoyable for all ages!), frolicks through some of the strangest stories in the history of medicine, accompanied by delightfully grotesque illustrations. There’s learning, there’s laughter, but most importantly, there’s a lesson: failure is okay. Not just okay but a necessary part of science. Tune in for all this and more!

As we learned last week, starvation extends far beyond hunger and what a lack of food does to the human body. Similarly, famine is much more than a food shortage and starvation on a population-level scale. This week, we’re picking up where we left off last episode to explore the definitions, drivers, and many dimensions of famine. We trace famines throughout human history, asking how they have changed either in their incidence, severity, or cause. No two famines are exactly alike, but taking a bird’s eye view of patterns in famine over time gives us insight, especially into the famines of the past 100 years. We conclude the episode with a discussion of the ongoing famine in Gaza and other food insecurity crises in other regions of the world.

Deprived of food, our bodies do the best they can to keep us alive and functioning as long as possible. As the days pass, the rhythms of our lives change: our metabolism, our heartbeats, our hormones, even our thoughts shift to adjust to this period of scarcity. This response is evolutionarily engrained, following a variable but fairly prescribed path. In this episode, we trace that path, exploring what happens when our bodies are not given the energy stores they need, how patterns of metabolism alter, leading our bodies to consume themselves, and the profound consequences this has on every part of our physiology and psychology. We also tell the story of how we came to learn about these outcomes, chiefly through a WWII-era study called the Minnesota Starvation Experiment. This is the first of two episodes centered around malnutrition, starvation, and famine. Next week, we’ll explore the broad topic of famine, of which starvation is merely one component.

The United States is in the midst of a monumental mental health crisis, with one in four people predicted to experience mental illness at some point in their lives. Adequate mental health care remains out of reach of so many due to a myriad of factors: unaffordability, stigma, shame, and racism, to name a few, leaving enormous gaps in mental health equity. The roots of these inequities can be traced back decades, to the earliest psychiatric hospitals founded on harmful racist notions of mental illness. In Madness: Race and Insanity in a Jim Crow Asylum, author and award-winning journalist Antonia Hylton explores the story of Crownsville Hospital, a segregated asylum in Anne Arundel County, Maryland, built in 1911 by its first patients: twelve Black men. Over the course of the 20th century, the shifting perspectives of race and mental illness played out in the overcrowded and understaffed Crownsville Hospital, with powerful implications for understanding our current failing to deliver adequate care to all in need. Madness is a powerful and necessary book that sheds much-needed light on the intersections between race, racism, and mental illness.

Every year, millions of babies around the world are screened for dozens of treatable conditions within the first day or two of life. What it takes is a few drops of blood on some filter paper, and what it gives is profound: potentially life-saving information. The advent of newborn screening is one of the greatest public achievements of the 20th century; since their earliest implementation, screening programs have diagnosed hundreds of thousands of babies early enough for medical intervention. And the life-saving potential they hold continues to grow with the development of genomic sequencing technology, which will increase the number of screenable conditions by an order of magnitude. In this episode, we explore the serendipitous origins of newborn screening, what the process looks like from a parent’s perspective, and how cutting-edge technology could revolutionize these programs. To help us navigate the exciting future of newborn screening, Dr. Joshua Milner, Professor of Pediatrics and Director of Allergy Immunology and Rheumatology at Columbia University Medical Center joins us to discuss an ambitious research program at NewYork-Presbyterian hospitals titled the GUARDIAN study, or Genomic Uniform-screening Against Rare Disease in All Newborns. Tune in for a truly thrilling episode!

None of us are ever truly alone. Our bodies are home to untold numbers of microbes, chilling on our skin, in our guts, throughout our respiratory tract, inside our bellybuttons, under our fingernails, and beyond. For the most part, we live in harmony with these critters, never giving them a second thought. But occasionally, they may grow a bit too friendly, taking advantage of our hospitality to grow and spread with abandon. Candida yeasts are especially fond of this tactic, leading to millions of infections around the globe each year, many of which can cause significant illness or even death. In this episode, we explore the characteristics of these yeasts that make them so prone to overgrowth, how severe infections can develop, and why one of medicine’s greatest achievements may have helped usher in this new fungal era.

When your car breaks down or your fridge goes on the fritz, you can order a replacement part and get things back up and running in no time. The same cannot always be said for another intricate machine: the human body. For centuries, scientists have grappled with making or transplanting suitable replacements for nearly every body part, from hearts to hair and from legs to lungs. We’ve come quite a long way in that quest, so that at times, it feels as though we’re living in a sci-fi novel, where skin cells are printed and we can grow a customized heart. Yet we still have further to go, thanks to our magnificent immune system, who proves to be quite a worthy opponent. Here to tell you all about the weird and wonderful world of regenerative medicine is the one and only Mary Roach, who joins us this week to chat about her latest book Replaceable You: Adventures in Human Anatomy.

Last week, we took you through all the ways that cold can harm us and the harrowing history of humans perishing at its icy hands. Ending the story there would be skipping over the parts where cold gets to play the hero, rather than the villain. In the second installment of this frosty miniseries, we explore the situations in which we might use cold to protect us and how it actually works. We also delve into the surprisingly long (and unsurprisingly grim) history of therapeutic hypothermia, a journey that wouldn’t be complete without a debate over sea cloaks, a reconsideration of the plot of Titanic, and a brief jaunt into cryonics.

For all our wondrous adaptations as a species - our big brains, our capacity for language, our opposable thumbs - we humans are not well-equipped to deal with the cold. Take us out of our insulated dwellings, take away our winter clothes, and things can get dicey fast. From frostbite to hypothermia, the cold can settle into our bones, leading us down a path where injury or death are possible outcomes. In this episode, we explore that path: how our meager cold-survival adaptations are vastly outshone by other animal species, the long and grim history of hypothermia in war, and what exactly is happening inside your body when your temperature drops.

The development of antibiotics was one of the greatest turning points in the history of medicine. Bacterial infections that were once death sentences were cured within a matter of days after administration of these lifesaving compounds. But the honeymoon didn’t last long, as resistant bacterial strains emerged and spread. Now, antimicrobial resistance poses one of the greatest threats to global health; frankly, we can’t invent new antibiotics faster than resistance develops. Fortunately, there may be a solution, one that has existed even before antibiotics came on the scene: phage therapy, the use of bacteriophages to treat bacterial infections. In The Living Medicine: How a Lifesaving Cure Was Nearly Lost—and Why It Will Rescue Us When Antibiotics Fail, author Lina Zeldovich takes readers through the incredible and long-forgotten story of phage therapy and the doctors who developed it. Tune in to learn how phage therapy, after almost being relegated to a footnote in the history of medicine, is reemerging as a possible solution to the deadly problem of antimicrobial resistance.

Some things just go together: peanut butter and jelly, bacon and eggs, milk and cereal, London and smog. Or at least, that’s the way things used to be until the Great Smog of 1952. (Don’t worry, the first three pairings are safe). If you’ve watched The Crown, you may remember an early episode in which a thick, noxious smog surrounded the entire city of London for days on end. People coughing, hacking, collapsing. Traffic ground to a standstill. Authorities in denial. What was actually going on in December 1952 to lead to such conditions? What was in the smog to make it so toxic? And how did this severe pollution event lead to massive changes in air quality regulations around the world?

For most of us, there probably hasn’t been a good reason for you to think about your gallbladder. Ever. Much of the time, it sits there, silently storing, concentrating, and, when needed, churning out bile every day. But occasionally, this unassuming organ will announce itself through waves of unceasing, excruciating pain brought on by a blockage of some sort. Why it does this to us, what we do about it, and how we can live a gallbladder-free life are just some of the things we cover in this episode. We’re also taking this opportunity to deep dive into the substance most closely associated with the gallbladder: bile. Bile plays an outsized role in the history of medicine, mostly through its role as one of the four humors in the humoral theory of disease. Are you of a choleric temperament or is your vibe more sanguine? Maybe melancholic or phlegmatic suits you better. Don’t know what the heck we’re talking about? Tune in to find out.

In the first years of the COVID pandemic, a debate raged: was the virus transmitted via respiratory droplets, or was it airborne? For some, this distinction seemed overly technical, pedantic even. But for others, it represented decades of dismissal and missed opportunities - opportunities that had cost untold lives. In this week’s TPWKY book club episode, renowned science writer and journalist Carl Zimmer joins us to discuss his latest book Airborne: The Hidden History of the Life We Breathe, which uncovers the long-forgotten story of an entire field of study - aerobiology - and the pioneering scientists who discovered life where there was thought to be none.

What’s in a name? What can you really tell from a label like “polycystic ovarian syndrome”? And how much of that is more misconception than truth? The answer, as it turns out, is the former. In this episode, we delve into the world of PCOS, a world that shows us how preconceived notions of health and disease, gender and sexuality can do far more harm than good. For many people with PCOS, this condition violates society’s expectations of how you should look, act, or feel. And the resulting stigma and shame deepens the silence that often surrounds PCOS and leads to inadequate treatment and medical gaslighting. But thanks to the work of some incredible advocates, that silence is slowly fading. Tune in to discover the many lessons that PCOS can teach us, if only we are willing to learn.

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.

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.

Content Warning: This episode includes mentions of miscarriage, pregnancy loss, pregnancy complications, traumatic birth experiences, and other potentially disturbing topics related to childbirth, pregnancy, and the postpartum period. 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. Tune in to learn more about these mushrooms that show death can come in small packages.

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.

Hemorrhagic virus? Check. Deadly disease? Check. Mosquito-borne? Check. Affected by animal movement, human activity, and environmental change? Check. Rift Valley Fever has all the markings of a classic TPWKY episode. This week, we’re doing a deep dive on this deadly virus, taking a One Health approach to explore the intricate relationships between animals, humans, and the environment to understand how this virus moves across the landscape. We trace the various paths this virus takes: through the organisms it infects, across the globe as it spreads, and over time as it appears to be evolving to be deadlier. Tune in to learn more about Rift Valley fever and what we might see with this pathogen in the years to come.

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? Tune in for a fascinating discussion that will stay on your mind long after your next movie night. And also check out Merle and Lee’s excellent podcast Infectious Historians!

Yes, the world may be out to get us with allergens around every corner, but we’ve got some tricks up our sleeve to help us cope. Our allergy treatment toolkit includes an impressive suite of tools, and in the second episode of our two-part series on allergies, we focus on three in particular: antihistamine medications, allergy shots, and the epinephrine auto-injector (aka the EpiPen). We take you through how exactly each of these work, trace their development from concept to product, and highlight some of the most promising areas of allergy treatment research today. Have you ever wondered why we have so many different types of antihistamines? Or thought about what the Cold War has to do with the EpiPen? Then this is the episode for you.

Sometimes it seems like the world is out to get us: bees in our garden, pollen in the air, nuts in our brownies, any number of other things that could trigger an allergic reaction ranging from itchy eyes and a runny nose all the way to anaphylaxis. Why must our bodies react in such over-the-top ways to these seemingly innocuous substances? In the first episode of our two-parter on allergies, we explore that very question. From the biological basis of an allergic reaction to the potential evolutionary significance of allergies, from the history of their discovery to the global status of allergies today, we cover it all.

In February 2012, Paul Volkman was sentenced to four consecutive terms of life imprisonment for his role in illegally prescribing and dispensing pain medications that resulted in the deaths of several individuals in his care. This was a remarkable case, both in terms of the lengthy sentence as well as the perpetrator. Paul Volkman was a highly-educated physician researcher, who earned both his MD and PhD and had decades of experience practicing medicine. How did he end up in a cash-only pain clinic in southern Ohio? In this TPWKY book club episode, journalist Philip Eil joins me to trace Volkman’s journey as outlined in Eil’s book Prescription for Pain: How a Once-Promising Doctor Became the “Pill Mill Killer”. Eil places Volkman’s actions in the broader context of the opioid epidemic and reflects on the lasting impact Volkman’s case has had on painkiller regulation and the communities most impacted by his crimes. Tune in for a fascinating conversation about what happens when a doctor decides he is above the law.

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). In this episode, we trace the story of the appendix from its earliest descriptions to the latest advancements in treatment of appendicitis. If you’ve ever wondered whether the appendix actually serves any function and what that function might be, then this is the episode for you!

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. Tune in to learn how the great scabies debate was finally resolved with a public demonstration, what role conscientious objectors played in scabies research during WWII, and where we are with scabies around the globe today.
