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 ways, and in this week’s book club episode, we delve into some of the more insidious and less explored impacts: those on our cognition, our mental health, our brains, and our behavior. In The Weight of Nature: How a Changing Climate Changes our Brains, author Clayton Page Aldern, neuroscientist and journalist who leads the data journalism program at Grist, presents a compelling and sweeping examination of the many unseen ways that climate change is changing us. Why do we have a shorter fuse when it’s hot outside? How are our memories and language impacted by our changing climate? What pathogens pose a greater threat to our brains as the climate warms? And most importantly, how can we begin to process these effects on our inner selves? Tune in to find out.

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. But do these spiders actually deserve all the hatred they get? In this week’s episode, we argue no. Breaking down not just the bite of thebrown recluse but also its behaviors, its distribution, and its lore, we present a more complete picture of this vilified arachnid. Tune in for the low down on this shy spider.

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, it finds you anyway, preying on health anxieties and promising an easy fix. In this week’s TPWKY book club episode, Dr. Deborah Cohen, medically-trained, award-winning journalist, broadcaster, and editor, joins me to discuss the implications of this flood of health misinformation, which she explores in her recent book Bad Influence: How the Internet Hijacked Our Health. From podcast bros touting peptide injections to TikTok influencers swearing by supplements, Cohen demonstrates that the internet is a wild west in desperate need of consumer protections. But it has also been a double-edged sword, providing community and connection alongside these bad actors. How can we continue to leverage the good of the internet to democratize health information while putting guardrails on nefarious wellness influencers hawking lies for profit? Tune in to find out.

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.
