Special Episode: Dr. Noah Whiteman & Most Delicious Poison

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).

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 omnystudio.com/listener for privacy information.

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.

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 omnystudio.com/listener for privacy information.

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 omnystudio.com/listener for privacy information.

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 omnystudio.com/listener for privacy information.

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).

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 omnystudio.com/listener for privacy information.
