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 misinformation. We delve into the story and science of statins and other cholesterol-lowering drugs, from their brilliant discovery to early promising trials, from barriers preventing their use to the heaps of misinformation abounding on the internet. How do statins actually work? What does penicillin have to do with their discovery? What's the deal with side effects? Tune in for all this and more.

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 HDL mean in the context of heart disease. Then we delve into the history of this compound, which involves an over 2 billion year journey back in time, fascinating experiments that revealed the stubborn nature of medicine, and a terrible - but hopefully memorable - baseball analogy. Tune in for the low down on cholesterol.

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 episode about the biology of Cyclospora cayetanensis, how this parasite makes you sick, when we first learned about it (more recently than you might think), and what we know about this current outbreak (or outbreaks). We also probe how recent changes to foodborne pathogen surveillance on a national scale are contributing to the challenges in understanding the scope and origin of outbreaks such as this.

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 these days, so why not use your free will to take advantage of that, whether through selling breast milk or freezing your eggs? But the global fertility industry is also blatantly exploitative, preying on those who are desperate and vulnerable in order to maximize profits. In Cash Cow: How the Maternal Body Became a Global Commodity - and the Hidden Costs for Women , author and journalist Alev Scott explores that blurred line between empowerment and exploitation in this globally varied industry. Her reporting takes her through the underbelly of the breast milk market, the complicated world of fertility tourism, and the legal and emotional turmoil of surrogacy. As she describes, the morality, legality, and expenses of different procedures are a moving target across the globe, reflecting the struggle to attach moral judgment when science and circumstances change so rapidly.

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 cerumen. The biology and history of earwax proves to be surprisingly rich and revealing and will have you second-guessing yourself as you reach for that cotton swab. Armed with this week's episode on earwax and last week's on boogers, you'll be ready to take on even the most daunting office icebreaker.

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, and this episode is our attempt at righting that wrong. What are boogers, and what purpose do they serve? How long have handkerchiefs been around, and when did mucus evolve? How many of us are nose-pickers, and how do other species deal with their boogers? More stuffed with snot facts than a nose during flu season, this episode has all the best tidbits to share at your next dinner party.

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 "whistleblower type"? What happens when there's no one left to hear the whistle being blown? These are just some of the questions we explore in this week's TPWKY book club episode, where I'm joined by Dr. Carl Elliott, [Professor of Philosophy at the University of Minnesota] to discuss his latest book The Occasional Human Sacrifice: Medical Experimentation and the Price of Saying No. In this profound and personal work, Dr. Elliott reflects on the drivers and consequences of blowing the whistle, interviewing whistleblowers in past scandals as well as drawing from his own experience. We may all think we'd do the right thing, but how many of us are prepared for the cost? Tune in for an enlightening conversation about medical ethics and human nature.

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 severe burn injuries. But this revolution in burn care is far from over. As we discover, thrilling research in this area is blurring the lines between science and science fiction. Bioengineered skin? 3D-printed skin scaffolding? Nanoparticles?

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 how we categorize burns based on severity. On the history side of things, we take a tour through humanity's quest to alleviate the pain and suffering caused by the near-universal experience of getting burned. Ever wondered what Hippocrates would have recommended for a burn? Or what distinguishes a second- from third-degree burn? Tune in to find out.

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 journalist Alexandra Sifferlin joins me to discuss The Elusive Body: Doctors, Patients, and the Diagnosis Crisis . Her compassionate and sweeping exploration of this topic takes readers across the US as she connects with patients, doctors, and researchers that are deeply impacted by the diagnosis crisis. While plumbing the depths of this pervasive issue, Sifferlin also encounters many people who have dedicated their careers to addressing the diagnosis crisis and bringing people the answers they need and deserve. Tune in for a fascinating conversation on a subject that has affected so many of us.

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 water, vehicle, or air? That's exactly what we're going to explore in this episode. From how long humans (and other species) have been coping with these debilitating symptoms to what's actually going on in your brain to trigger the breakdown, from what's in the most nauseating historical "cures" for motion sickness to why the drugs we have today have some positive effect, we're covering it all.

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 features a surprise discovery, more evidence that everything is tuberculosis, and a spotlight on an extinct bird. Curious to know how all the pieces fit together? Tune in for the full picture.

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 outcast and not fit for polite company. Skyrocketing infection rates drove a corresponding rise in syphilis "cures" and an increasingly desperate public. In this TPWKY book club episode, Dr. Olivia Weisser , associate professor of history at the University of Massachusetts, Boston joins me to discuss her recent book The Dreaded Pox: Sex and Disease in Early Modern London . She transports readers to the hidden shops and stalls that promised a remedy to this feared disease, to the courthouses where a syphilis infection was an important piece of evidence, and to the country houses that held recipe books for those who could not purchase a cure. Tune in for a fascinating glimpse into a time and place where morality, sex, and disease were so strongly entangled.

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 guidelines, we get to the bottom of the latest iteration of these guidelines and investigate which changes are good (there are a few), which are bad (definitely a few there), and which are somewhere in between. Then we explore what science has actually shown about what constitutes a "healthy" diet. Tune in for a lively discussion that features lots of complaining about protein-enriched products, exasperated sighs, and a few shocking revelations about "the American diet."

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 dietary guidelines and how their intentions have evolved as the food landscape drastically changed over the 20th century. Then we interrogate the conflicts of interests at the heart of their formation, questioning how much these recommendations are backed by science vs industry interests. Ultimately, we come back to the question of "if few people actually use these guidelines, why should we care about them at all?" Turns out, we have lots of feelings on the matter.

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 Kucharski , Professor at the London School of Hygiene and Tropical Medicine joins me to discuss latest book, Proof: The Art and Science of Certainty . With this book, Dr. Kucharski presents a compelling and thoughtful examination of the concept of proof, delving into topics ranging from the justice system (what's a reasonable doubt?) to infectious disease, clinical design to the founding of this country. And he leaves us with a powerful lesson: what convinced you of something might not convince someone else. Tune in for a fascinating conversation!

Tear gas is an expected, normalized part of protests today. But its use in international war is banned. How can that be? That's just one of the questions we investigate in this episode. First, we take you through the long history of tear gas and its emergence alongside deadlier chemical weapons before discussing how its use became routine, fueled by industry interests. Then we delve into what's in tear gas that causes the painful physical reaction and consider whether claims of non-toxicity are backed up by research (spoilers: not really). This is an info-packed episode that will leave you with many questions answered, but not all of those answers will be satisfying.

Though discovered relatively recently, Oropouche virus has been making headlines as an emerging vector-borne infectious disease on the rise. Not transmitted by the usual suspects (like ticks and mosquitoes), this virus is instead spread through the bites of midges or no-see-ums. Since these arthropods are already widely distributed and their range is growing thanks to climate change, this is a recipe for potential disaster. In this episode, we take you through the story of Oropouche virus, from how it makes us sick to what the construction of a highway has to do with its discovery, from surprising prevalence statistics to the history of One Health. Tune in for the full scoop on this midge and the virus it carries.

For the entirety of our species' history, our approach to cancer has largely been to react, to design new therapies and better combinations of treatments. This energy has certainly been well-spent, but what if we didn't have to use treatment at all? Or what if we could minimize the use of aggressive therapies? Prevention and screening represent two under-appreciated pillars of cancer care, and we're using this final installment in our cancer miniseries to show some appreciation. To grasp the impact that screening and prevention can have, we also need to consider the global landscape of cancer prevalence and incidence - where is it decreasing? Where is it on the rise? Where can intervention or prevention make an impact? As we've shown over these four episodes, science and medicine has accumulated a wealth of information about cancer - but the striking racial and socioeconomic disparities in cancer incidence and mortality in the US and around the world demonstrates that that knowledge has not been applied equally. Any proposal to reduce the global cancer burden must address the systemic issues driving these disparities. Tune in for a thought-provoking reflection on the status of cancer today.

A century and a half ago, the list of effective cancer treatments was essentially a single entry: surgery. Today, in 2026, you'd need pages to contain the number of treatments available, and multiple notebooks to delineate all of the various therapies currently in development. It is nothing short of a revolution. Of course, no revolution is perfect, and many cancer treatments are ineffective or carry risks of serious side effects. In part 3 of our cancer series, we delve into all facets of cancer treatment, from the history of their development to how they actually work. Tune in to learn how far we've come and where we might go from here in our perennial quest to treat and cure cancer.

For centuries, physicians noticed that cancer sometimes ran in families, but until the 1960s, an answer to this mystery remained out of reach. Only then were scientists beginning to unlock the cellular dynamics underlying cancer, and what they found finally allowed grief-stricken families to put a name and explanation to their experience. It wasn't simply bad luck. It was genetics: a heritable mutation in a key tumor suppressor gene that greatly increases the risk of developing cancer in your lifetime, a condition known as Li-Fraumeni Syndrome. Journalist Lawrence Ingrassia belongs to one of those families; he has lost his mother, three siblings, and a nephew to cancer. In this TPWKY book club episode, Ingrassia joins me to discuss his book A Fatal Inheritance: How a Family Misfortune Revealed a Deadly Medical Mystery , where he weaves together his family's story with that of the scientists who sought to uncover the cellular drivers of cancer.

Each of our cells can become cancerous. It's an uncomfortable, yet unavoidable truth. Nor is it a truth restricted to our species - cancer is a consequence of complex life. The features that make a cell cancerous are those that, under other circumstances, are beneficial, essential even, for an individual's growth and survival. How is that possible? In the second installment in our series, we're putting cancer under the microscope to consider the qualities that underlie a cancer cell's success in our body. By placing cancer in an evolutionary framework, we can not only understand why cancer is so darn prevalent, but we can also leverage that knowledge to devise new approaches to treatment - working with evolution rather than against it. If you've ever wondered why we haven't come up with a cure for all cancer or why some animals get cancer more than others, this is the episode for you.

Cancer has touched every one of us in some capacity, and learning of a diagnosis inspires many more questions than it answers. In this four-part series on cancer, we aim to lay a foundation of knowledge that will help make sense of this multifaceted disease. We begin our four-part series on cancer by asking a deceptively simple question: what is cancer? As we'll discover over the course of these episodes, there is not one answer but many. After all, cancer is not one disease but many. In this first episode, we examine the clinical definitions of cancer - when someone receives a cancer diagnosis, how is that determined, and what does that mean? Viewing that question through a historical lens reveals our changing understanding of cancer and how that knowledge filters into the public perception of this disease. With cancer diagnoses on the rise, it's tempting to label cancer a disease of the 20th or 21st centuries. But is that the case? Tune in to find out.

What happens if you put a bunch of rats in an enclosure and provision them with unlimited food and water? Researcher John B. Calhoun was committed to finding out. Results from Calhoun's "rat utopia" experiments from the mid-20th century revealed a behavioral dark side that emerged as space grew increasingly limited, ultimately leading to complete population collapse. As headlines conveyed dire warnings about global overpopulation, Calhoun's work served to reinforce those fears and shape our understanding of the importance of personal space. In this week's TPWKY book club episode, Jon Adams and Edmund Ramsden join me to discuss their book, Rat City: Overcrowding and Urban Derangement in the Rodent Universes of John B. Calhoun . Tune in for a fascinating a tour through Calhoun's bizarre and influential research, which even inspired a beloved (if a little creepy) children's book and movie, Mrs. Frisby and the Rats of NIMH.

Poop is an incredibly valuable and massively underutilized resource. However, most of us don't see it that way because of our evolutionarily ingrained disgust towards poop. Flush toilets and intricate sewer systems have revolutionized health and hygiene by whisking our poop far away where we don't have to think about it. But that poop has gotta go somewhere, and eventually, not thinking about it isn't going to be an option. Similarly, not thinking about our individual poop is asking for disaster, since what we produce can reveal a great deal about our gut and overall health. In this episode, we explore the problems that poop can cause on both the individual and population level. From constipation to fiber, and the Great Stink to communal poop sponges, we're continuing our journey into the curiously fascinating world of poop.
