In 1518 a strange sight could be seen all over the town of Strasbourg. Crowds of people dancing unceasingly, unable to control their movements, seemingly heedless of their blistered and bloodied feet. As the contagious dance grew, so did the body count as the frenzied dancers succumbed to exhaustion. Over 500 years later, this dancing plague leaves us with many questions, first among them being, “...

From the behavior-altering effects on rodents to the ancestral origins of the domestic cat, we d...

This episode, our first foray into toxic metals, is heavy in all kinds of ways - metallically, emotionally, informationally, politically.

Tune in to hear us chat about the multitude of effects...

E. coli . Such a short name for such a massive topic.

For our last episode of this season, we’re going out with a bang, or should we say bite? This week we’re tackling the doozy of a disease called Lyme, the most prevalent tick-borne infection in the northern hemisphere.

Despite being one of the most common genetic disorders, affecting millions of people worldwide, cystic fibrosis evaded medical description for thousands of years after its first appearance. But the last century has led to a revolution in diagnosis, treatment, and our understanding of the disease. This week we talk all things cystic fibrosis, from salty sweaty tests to European folklore, from Bell...

Walking through a forest at dusk, you’ve likely heard the croaks and groans of frogs and toads forming a chorus in the damp undergrowth. But what if the forest were suddenly, inexplicably, silent? In the 1980s scientists started noticing the forests becoming quieter as amphibian populations around the globe began to decline -- rapidly. Today we are joined by Dr. Taegan McMahon from the University...

What exactly is disease ecology anyway? How did  TPWKY come to be? How do we come up with our quarantinis? What’s our favorite pathogen?

From what are the effects of climate change on vector-borne disease to what we were like at age nine,...

Giardia may be the most common intestinal parasite in the US and one of the most common worldwide, but did you know it was only in the last 40 years that it was officially recognized as a human pathogen?! In today’s episode, we’ll travel back to a time before humans knew microbes even existed to discover alongside Leeuwenhoek a whole new world of animalcules like giardia. We’ll find out how seeing...

Imagine this: a sickness where millions fell into a deep slumber from which they never woke. Of those that did, many remained trapped in a cage of their own bodies, unable to move or speak but fully aware of the world around them. Imagine that this sickness appeared suddenly, without warning, and spread across the globe, affecting millions in just a few decades. Then, just as quickly as it emerged...

On this very special crossover episode with our friend Matt Candeias from In Defense of Plants, we’re switching things up from poison to remedy, focusing on the plant-derived wonder drug, aspirin! We cover the ancient use of salicylic acid-containing willow bark to relieve pain and fevers and then reveal how such a harsh compound was transformed into a useable pharmaceutical. We also delve into wh...

This week's episode comes with a warning: don't attempt this at home. While self-experimentation has led to many a scientific breakthrough, we're definitely not advocating it. But it happened to work out for the best for Barry Marshall and Robin Warren, even earning them a Nobel prize. That’s right folks, today we’re talking about none other than  Helicobacter pylori , the curvy little bacterium i...

Zika virus may not have as long and storied a history as many diseases we've covered, but in a short time it has managed to make a big impression. Today we'll talk about how Zika wriggled its way out of obscurity and cover its journey from a mosquito's mouth straight to our newspaper headlines. From the first discovery of the virus in a Ugandan jungle, to the heartbreaking effects only recently di...

Today we’re taking a bite out of hookworm, our first macroparasite. We start, as all hookworm journeys must, from the dewy grass, where larvae burrow into your exposed flesh and make their long and winding way to your guts, where the eggs of a fortunate few will be immortalized in fossilized poop. It’s a tale of human migration, of failed eradication, and of overburdened populations. So pull up a...

Are you ready to dilate your mind? Or at least your eyes? We hope so, because that means you’re ready for another Poisoncast episode!

And not just any protein, a protein you  already have in your body . Are you sweating yet? Good. The...

Arr, mateys, climb aboard for a swash-buckling tale of when the high seas were full of disease! Today we’re covering a non-infectious but no less terrifying scourge that has wrecked millions of lives and sent even the bravest of sailors quivering in their boots: Scurvy. From the open ocean to the California gold rush to modern times, scurvy has been causing collagen breakdown throughout human hist...
