This Podcast Will Kill You

Already this summer, heatwaves are causing thousands of deaths across the world, catastrophic flooding threatens millions, wildfires rage across enormous swathes of the globe, many regions face extreme drought conditions, and a very strong El Niño is predicted for later this year, leading to further climate chaos. It’s a lot to take in. The devastating consequences of climate change can be measured any number of ...

Few spiders hold the dubious honor of name recognition among the general public. Most that do, like black widows, Australian funnel-web, the Goliath birdeater, are renowned not for their cute colors or weaving skills but for being fearsome, dangerous predators. The brown recluse is no exception. A bite from one of these arachnids can send someone to the hospital with a painful necrotizing wound and weeks of recovery. ...

If you have a medical question, where do you turn? How often is google or social media your first stop? As you sift through the AI overview and countless reels professing to have the answers, it becomes harder and harder to separate fact from fiction. Do these supplements actually do what they promise? Should I be wary of this commonly prescribed medication? Even if you’re not directly seeking this information, i...

Last week, we set the stage by breaking down the science behind cholesterol: how it moves through our body, why it causes disease, and when we discovered the link between LDL and atherosclerosis. This week, armed with that knowledge, we’re asking the big question: what do we do about high cholesterol? Statins emerged as a highly effective intervention but one that is not without its share of controversy and misin...

So your latest blood test results have come in, and you see a couple of numbers for cholesterol. What do those numbers mean, and why do we care about them? In this first part of our cholesterol miniseries, we break down the science behind this compound and trace how we made the link between certain types of cholesterol and heart disease. First, we follow the path that cholesterol takes in our bodies and what LDL and HD...

You’ve seen the headlines: a food-borne parasite is infecting people across the US, leaving them chained to the toilet sometimes for weeks on end, as they are ravaged by wave after wave of gastrointestinal upset. What the heck is cyclosporiasis and where did it come from? How scared should we be of our raspberries or lettuce or cilantro? To dish out the answers as fast we could, we put together this fact-filled e...

Social media ads for egg freezing. A craigslist-like site for breast milk. Fertility fairs featuring IVF clinics alongside shamanic nutritionists. Surrogacy contracts offering a discount for multiple embryos. The rapidly-growing global fertility industry promises hope, fulfillment, and control, as long as you can afford it. Participating in this industry can be empowering. All parts of reproduction are commodified thes...

In keeping with last week’s theme of “bodily excretions that are kinda gross that you don’t really think about but are actually really important”, we’re devoting this episode to earwax, aka cerumen. In one hour, we somehow manage to weave together stories of earwax impaction, misadventures in ear candling, glimpses of earwax in art history, and a whale of a tale as revealed by cetacean cer...

Hard and crusty. Green and gloopy. Clear and watery. Boogers come in a veritable rainbow of colors and a full spectrum of textures from liquid to solid. They’re really quite impressive if you think about it. Which, of course, few of us do, besides adding tissues to our shopping list or cursing the dagger-like boogers that emerge during a trip to a particularly dry locale. But boogers deserve a lot more credit, an...

Stories of unethical medical experimentation often center around the individuals who spearheaded such atrocities or highlight how patient protection laws were changed in response to the studies. But rarely do they focus on the people who fought to bring these harms to light: the whistleblower. What does it take to blow the whistle, and what does it cost? Are we all capable of blowing the whistle or is there a “wh...

At the turn of the 20th century, a severe burn was often a death sentence. Today, that is no longer the case. Over the past eighty years, burn care has undergone a profound transformation thanks to crucial advances across diverse areas of medicine, such as skin grafting, antiseptic technique, and fluid balance. In this episode, we trace how those pieces of the puzzle were integrated to bring new hope to those with seve...

Burns have been a part of the human experience since our hominin relatives began controlling fire 1.5 million years ago. Until very recently, we’ve been limited in our ability to manage burn wounds with any success, having instead to rely on our body’s innate healing responses. In this episode, we delve into those repair responses, explore what makes burns different from other types of injuries, and examine...

An accurate diagnosis can give us so much. It can give us a path forward. It can give us answers to long-standing questions. And it can give us much-needed hope. Yet many people around the world wait years to receive an accurate diagnosis, which can take a profound physical and emotional toll. What underlies these missed or incorrect diagnoses, and what can we do about it? In this week’s TPWKY book club episode, health journa...

It comes on sneakily. You become aware of your stomach. You break out in a cold sweat. Your mouth fills with saliva. And before you know it, you’re leaning over the side of the boat (or out of the car, or into the airplane sick bag), barfing up your breakfast. Motion sickness. We’ve all been there, or at least most of us have. Why? What is it about our physiology that breaks down as soon as we travel via wa...

Once thought to be a rare, always fatal disease, histoplasmosis is now recognized as one of the most prevalent fungal infections in North America. It infects hundreds of thousands of people every year, and its distribution is growing. In this episode, we dissect this abundant fungus, examining how it makes us sick, who tends to get sick, and what we can do about it. We also take you through the history of this fungus, a story that ...

In a time when smallpox, tuberculosis, measles, and typhus ran rampant through the streets of London, there was another disease that instilled even more fear than these other killers: syphilis. So feared and so stigmatized was syphilis that it was sometimes called “the secret disease.” A diagnosis would not only sentence you to a drawn-out and painful illness possibly resulting in death, it also labeled you as an outcas...

If you’ve come across the latest dietary guidelines, a few things may have caught your attention: a big ol’ steak front and center in the new “inverted pyramid”, beef tallow and butter recommended as “healthy” fats, a declaration that the war on protein is ending. “Since when have we been at war with protein?” you may reasonably ask. In part 2 of our episodes on dietary g...

Over the decades, dietary guidelines have taken a diverse array of shapes, from pamphlets to wheels, from plates to pyramids. In many cases, the shapes have changed more than the recommendations they contain. This week and next, we explore those recommendations - who’s making them, how they have changed over time, and how closely they align with what we should be eating. First, we delve into the long history of d...

Why do we believe what we believe? Is what we believe the truth? How can we convince others of our beliefs? If you’ve ever found yourself pondering these questions, you know that the answers are rarely clear-cut. We need to form beliefs in order to navigate the world, but how skilled are we at evaluating evidence for those beliefs or weighing new data that contradicts them? In this week’s TPWKY book club episode, Adam K...
