This just might be our itchiest episode yet, and for that we sincerely apologize. But it might also be one of our most fascinating and fun episodes yet, and for that we are proud. Whether or not you have personal experience with bedbugs, the mere mention of these vampiric critters is often enough to inspire skin-crawling horror in us all. But in this episode, we also make a case for their appreciation. How can you not admire (from a distance, of course), their incredible ability to go for months or even a year without feeding? Or that their saliva contains all kinds of proteins that slow blood clotting or dilate our blood vessels? Or that the ubiquity of these bugs during the Industrial Revolution drove massive changes in furniture design? From the biology of a bedbug bite to the impressively long history of these blood-feeding arthropods, we present the story of bedbugs in more detail than you ever knew you wanted (and trust us, you do).See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Ep 117 Bedbugs: Bug-bitten and bedeviled

Menstruation. Is there any other biological process that is so widely experienced yet is still discussed in hushed tones or with an air of disgust? Period product commercials that never mention menstruation (and what’s with the blue liquid?), sex education classes covering what periods are without advising how to manage them, the endless list of menstruation euphemisms, prominent evolutionary hypotheses dismissing periods as maladaptive, even proposed laws forbidding the discussion of periods in school (looking at you, Florida) - these are just a few examples of the ways that we have been taught to be ashamed or grossed out by a natural biological process. In this TPWKY book club episode, we chat with Dr. Kate Clancy, Professor of Anthropology at the University of Illinois, about her recently published book Period: The Real Story of Menstruation, a compelling must-read that examines both scientific and societal perceptions of periods. Our conversation with Dr. Clancy takes us through the origins of period stigma, the leading hypotheses as to why we get periods, the observed link between the SARS-CoV-2 vaccine and menstruation, the hopeful period future, and so much more. Tune in to learn where a uterus pancake fits into this discussion and stay to have all of your period myths busted.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Even if you haven’t watched the TV show House MD, you’re probably familiar with the phrase “it’s never lupus”. But have you stopped to consider why it’s never lupus? Or why lupus is so often suspected in the first case? Well, dear listeners, this episode aims to get at the heart of those questions, which is easier said than done. Like many other autoimmune diseases, lupus erythematosus continues to baffle, but we know a lot more now than we used to. In this episode, we take you through that knowledge as best we can and then trace the steps of how we came to first recognize, then describe, and then treat lupus, a journey that takes us through how we learned about autoimmunity in the first place. If you’ve ever been curious about how lupus got its name (wolf bite, anyone?) or what the pregnancy compensation hypothesis could mean for this and other autoimmune diseases, then this is the episode for you.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Ep 116 It's never lupus (except this time)

In our episode on the bends, you joined us as we explored how low we can go. Now we’re back with a similar invitation: come along to learn how high we can fly (and what happens to our bodies when we get up there). In this very special episode, we examine the short-term effects and potentially deadly consequences of life at great heights and ask how we came to understand the relationship between altitude, oxygen, and health. This journey begins earlier than you may have guessed, back to a time before oxygen was discovered, and winds through unexpected avenues, including misadventures in hot air balloons and early experiments demonstrating the vitality of air, as we trace how the pieces of high altitude physiology were put together. A big part of what makes this episode so very special is our guest, Dr. Jonathan Velotta, Assistant Professor of Evolutionary Biology at the University of Denver, who joins us to chat about some of the incredible ways that humans and other animals have adapted to live at high altitude. Tune in for a bird’s-eye view of what it’s like to have a high life.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Ep 115 Altitude Sickness: Balloons though?

Listeners of this podcast are likely no strangers to the horrifying history of eugenics, a topic that has made an appearance in our episodes on epilepsy, Huntington’s disease, hemophilia, sickle cell anemia, and many others. We have touched on eugenic policies that prohibited marriage, encouraged and permitted forced sterilization, and restricted immigration in the U.S. in the early 20th century. But what we haven’t explored in great depth are the origins of eugenics as well as its disturbing persistence in scientific research today. This week’s TPWKY book club selection, Superior: The Return of Race Science, goes way beyond filling in those gaps, offering a brilliant, disturbing, and much-needed examination of the history and continued practice of race science. In this bonus episode, Angela Saini, award-winning journalist and author of Superior (and many other must-read books), joins us to discuss this history, exploring questions such as “what role did colonialism play in the creation of racial categories?”, “where does the public image makeover of Neanderthals fit into this story?”, “what does race science look like today?”, and “how did race science make an appearance during the COVID pandemic?”. Tune in for a fascinating interview that highlights the need to remain vigilant against the insidious and damaging practice of race science.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

For many of us, our encounters with listeria may not go beyond reading the occasional headline about an outbreak from contaminated hot dogs or listening to our doctor advise us to avoid certain foods while pregnant. But as we explore in this episode, the story of Listeria monocytogenes is more complex, scary, and unexpected than you may have imagined. Join us this episode as we trace the dual-natured and sometimes extremely deadly infections this pathogen can cause, examine how the industrial revolution and cattle movements may have altered the landscape of Listeria monocytogenes, and ask why cell biologists are so enamored with this bacterium. One thing’s for sure: this isn’t your typical food-borne pathogen.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Ep 114 Listeria: It put dairy on the map

You may be wondering if there’s a typo in this week’s TPWKY book club selection - The Joy of Sweat? Are we supposed to find joy in this secretion? Shouldn’t it be The Inconvenience of Sweat? Some of you sauna-goers or hot yoga enthusiasts may already welcome sweat (at the right time and place, of course), but I’m guessing there are plenty of you out there that do everything you can to prevent perspiration and the odor that frequently accompanies it. In this bonus episode, Sarah Everts (@saraeverts), author of The Joy of Sweat: The Strange Science of Perspiration and Science Journalism Chair at Carleton University’s School of Journalism, joins us to discuss why we should reconsider our stance on sweat and instead recognize it for the superpower it is. Or at the very least, be grateful that we don’t do what vultures do to cool off. Our conversation covers topics as far-ranging as sweat forensics, the evolutionary significance of body odor, the shameful marketing of early antiperspirants, the wild world of sweat dating, and so much more. Whatever your current feelings towards perspiration, this episode will have you thinking more about sweaty secretions than you ever have before (and enjoying every second of it).See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Special Episode: Sarah Everts & The Joy of Sweat

There is no shortage of ailments that vitamin D has been claimed to prevent or cure - various types of cancers, heart disease, COVID-19, diabetes, an assortment of autoimmune conditions, just to name a few. What is it about this micronutrient that leads people to behold it as a panacea? In this episode, we sift through what we know about the biology of vitamin D, along with what happens when you don’t have enough of it, in an attempt to discern what might be overhype and what might be underhype when it comes to vitamin D and health claims. And there certainly is ample reason for excitement over this micronutrient, as its deep, deep evolutionary history reveals just how many biological processes in which vitamin D is intimately and vitally involved. The consequences of vitamin D deficiency form a large part of its human history, as soaring rates of rickets during the Industrial Revolution drew the interest of researchers intent on pinpointing the cause of this disease. As is typical for this podcast, the more we know, the more questions we have, like “who decided what counts as deficiency?”, “how much vitamin D should people be getting?”, and “what is vitamin D really telling us?”. Tune in for plenty of sunshine, cod liver oil, and drama over vitamin D.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Ep 113 Vitamin D: The D stands for drama

What do you get when you combine a love of reading with an interest in biology/public health/medical history and a background in podcasting? The TPWKY book club, of course! This season’s miniseries of bonus episodes features interviews with authors of popular science books, covering topics ranging from why sweat matters to the history of food safety, from the menstrual cycle to the persistence of race science and so much more. So dust off that library card, crack open that e-reader, fire up those earbuds, do whatever it takes to get yourself ready for the nerdiest book club yet.We’re starting off this book club strong with a discussion of Breathless: The Scientific Race to Defeat a Deadly Virus, the latest book by award-winning science writer David Quammen (@DavidQuammen). Breathless recounts the fascinating - and sometimes frightening - story of how scientists sought to uncover the secrets of SARS-CoV-2, the virus that causes COVID. In this interview, Quammen, whose 2012 book Spillover explores the increasing pathogen exchange occurring among humans, wildlife, and domestic animals, shares with us how he decided to write Breathless and why this story of discovery needs to be told. Our conversation takes us into musings over why we saw this pandemic coming yet could not keep it from happening, the controversy over the origins of SARS-CoV-2, and the question of whether future pandemics are preventable or inevitable. Through this discussion, we find that the global response to future pandemics depends just as much on locating the gaps in our knowledge about this virus as it does on applying what we have learned so far. Tune in for all this and more.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Special Episode: David Quammen & Breathless

Only our second episode of the season and we’re already getting in over (and inside) our heads with one of the biggest topics we’ve taken on yet: epilepsy. In this episode, we navigate the constantly changing definitions of epilepsy, make our way through the many different types of seizures, and dig into the inner workings of the brain as we attempt to understand the pathophysiology of this disease. And that’s just the biology section! The history of epilepsy proves to be just as intense, as shown by the multitude of meanings this disease has held over thousands of years. The past merges with the present - and maybe the future - when we delve into some of the technologies that have helped us to gain a clearer picture of this disease and may lead to improvements in prevention, detection, and management of seizures in years to come.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Ep 112 Epilepsy: It’s always the phlegm

We’re kicking off our sixth season in the same way we ended our fifth: with another headline-making respiratory virus. But as our listeners know, not all respiratory viruses are the same, and it’s often those differences among them that play the biggest role in their spread or the symptoms they cause. This episode, we’re exploring the virus that everyone has been talking about lately. No, not that one. Or that one. The other one. Yes, we’re talking about respiratory syncytial virus, or RSV. For many people, the recent surge in RSV infections that dominated headlines this winter may have been the first time they had heard of this viral infection or realized how deadly it could be. But for others, RSV has long inspired fear and dread. In this episode, we Erins explain why this virus deserves such notoriety, how long we’ve recognized the dangers of infection, and what hope the future may hold for novel RSV treatments or vaccines. If at any point you’ve wondered what all the fuss is about this virus or how to pronounce syncytial, then this is the episode for you!See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Ep 111 RSV: What’s syncytial anyway?

Ep 110 Influenza, Take 2: Sitting Ducks; Fowl PlayOver five years ago, on October 31, 2017, the very first episode of This Podcast Will Kill You premiered, an action-packed (and mildly disorganized) tour of the influenza virus and the 1918 flu pandemic. So much has happened since that episode’s release, both within the podcast and in the world of public health, not the least of which is a respiratory virus pandemic. Given this distance from the podcast’s beginning and the added perspective of experiencing a pandemic firsthand, we decided to circle back to where we started by revisiting influenza for our fifth season finale. In this episode, we provide a bird’s eye view of influenza viruses overall, from how they make you sick to the long history of influenza pandemics and where we stand with case numbers in recent years. Then we dig deeper by giving you a different kind of bird’s eye view: a close examination of highly pathogenic avian influenza, especially H5N1. How is this virus different from your standard seasonal influenza strain, where did it come from, and how worried do we need to be? Are we just a bunch of sitting ducks? Tune in to find out.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Ep 110 Influenza, Take 2: Fowl Play

Somehow it’s taken us until the penultimate episode to cover this season’s first mosquito-borne virus. But we assure you, this episode is well-worth the wait. Although Chikungunya virus is often lumped in with dengue or Zika, the unique characteristics that distinguish Chikungunya virus from these other arboviruses are just as important to note as the similarities among them. In this episode, we explore these differences and similarities in the biology of Chikungunya virus before reassessing what we thought we knew about the history of this disease, a history that is presently under revision. Finally, we wrap up the episode as we always do, by taking stock of where we stand with Chikungunya virus today. Tune in for a good deal of dengue compare/contrast, a whodunnit (or whichdiseaseisit) in the history of these two diseases, and a frustrating attempt to gather present-day case numbers.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Ep 109 Chikungunya: Not dengue (or is it?)

Although today we tend to think about diseases in terms of signs and symptoms, tests and treatments, that hasn’t always been the case. For much of history, diseases carried with them a deeper meaning beyond the pathophysiological processes leading to their development. A diagnosis was as much about the identity and personality of an individual as it was about the disease itself, and this was especially the case for the topic of today’s episode: gout. But before we get into the tangled history of this “monarch among maladies”, we first break down its biology and possible evolutionary origins. Once we have a solid understanding of this crystalline illness, we turn our attention to the changing perceptions of gout over time and why gout was once a welcomed diagnosis, in sharp contrast with so many other diseases. Finally, we take stock of gout around the world today, no easy feat. Tune in for a fascinating deep dive into this incredibly common but often overlooked illness.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Ep 108 Gout: Toetally fascinating

Over the years of the podcast, we have often struggled with questions of why: why pathogens act the way they do, why certain people get sick while others don’t, or why we know little about some diseases. This episode is no exception - sepsis certainly inspires many “whys”. But for perhaps the first time on the pod, we find ourselves grappling not only with “why?” but also with “what?”. What, indeed, is sepsis? Ask a dozen doctors and you may get a dozen different answers. Our first goal for this episode is to sift through the various definitions of sepsis and what we know about its pathology to get a firm handle on this deadly consequence of infection. We then turn our sights to a thrilling period of sepsis history - Joseph Lister and his carbolic acid spray - before attempting to address the status of sepsis around the world today. By the end of the episode, your picture of sepsis may not be crystal clear, but hopefully the edges are a little less blurry.And helping us to de-blur the edges of sepsis is the wonderful Katy Grainger, leading sepsis and amputee advocate and on the Board of Directors of Sepsis Alliance, who shares with us her harrowing sepsis experience. You can learn more about Katy’s story and advocacy work by following her on instagram (@katysepsisamputee), TikTok (@katysepsisamputee), Facebook, or by checking out www.sepsis.org.

Ep 107 Sepsis: It's a mess

This podcast might not actually kill you, but it covers so many things that can. Each episode tackles a different disease, from its history, to its biology, and finally, how scared you need to be. Ecologists and epidemiologists Erin Welsh and Erin Allmann Updyke make infectious diseases acceptable fodder for dinner party conversation and provide the perfect cocktail recipe to match.
