Tiny Matters

In this special bonus episode, we join American Medieval with host Matthew Gabriele, a professor of medieval studies and who knows about a LOT of history that we don’t. We're there to chat with Matt about some new science research surrounding the Turin Shroud — a cloth that many Christians believe was used to wrap Jesus after he was killed. The debates over this artifact are fascinating and the science only adds to it! So if you like science, history, and a little controversy, you’re going to love this episode. 

American Medieval is a podcast about the Middle Ages, but with an American twist. Each week, Professor Matthew Gabriele is joined by expert guests to explore either some fascinating part of the medieval world, or some way Americans have used this period to help them understand themselves.

Matthew Gabriele is a professor of Medieval History and an elected Fellow of the Royal Historical Society (UK). In addition to hosting the podcast "American Medieval," he’s the co-author of the books The Bright Ages: A New History of Medieval Europe (Harper Books, 2021), and Oathbreakers: The War of Brothers that Shattered an Empire and Made Medieval Europe (Harper Books, 2024). His new book, Violence: A Christian History, will be out with WW Norton in late 2027/ early 2028.

Single-celled marine organisms called foraminifera may be microscopic, but they've had a massive impact on life on Earth. They also leave behind intricate shells that have become part of a fossil record stretching back more than 500 million years. Today, they're one of the most powerful tools scientists have for reconstructing Earth's past climates, helping us put the current (alarming) state of our warming planet into context.

In this episode of Tiny Show and Tell Us, we discuss new blood tests and research into blood biomarkers that could make diagnosing endometriosis faster and less invasive. Next, we unpack subsynchronous resonance, a phenomenon that can damage power infrastructure, and is gaining new attention with so many AI data centers being built across the country. Then we hear from guest Emily Schneider who shares some delicious (maybe? You be the judge!) new research where scientists have engineered yeast to convert plastic waste and agricultural leftovers into cookies.

Scientists spent decades searching for viruses by filtering out anything too large to be one. That strategy seemed to work well... until it didn't. When researchers discovered a microbe living inside an amoeba that looked like a bacterium but behaved like something else entirely, they uncovered a hidden world of giant viruses with massive genomes, unusual genes, and even their own viral parasites. In this episode, we dive into the discoveries that forced scientists to rethink what viruses are, how they evolve, and whether the rules historically used to define them still hold up.

In this episode of Tiny Show and Tell Us, we explore how scientists are using evolutionary methods to reconstruct the history of folktales like Little Red Riding Hood, Beauty and the Beast, and Jack and the Beanstalk. Then guest Matt Gabriele, professor of medieval studies and host of the podcast American Medieval, shares his fascination with Greenland sharks, leading us into the science of radiocarbon dating, longevity genetics, and the ongoing debate over whether these elusive deep-sea predators truly live for 400 years or more.

Before modern blood transfusions, doctors tried some odd alternatives, including cow's milk. In this episode, we trace the fascinating history of blood transfusions, from risky animal experiments and failed milk injections to the discovery of blood types and disease screening. You'll hear how blood transfusions became one of medicine's safest procedures, why researchers are still debating exactly when patients need them, and what innovations could make blood easier to store, transport, and use in emergency situations including the military battlefield.

In this episode of Tiny Show and Tell Us, we dive into the surprisingly elaborate world of occlupanids: the humble plastic bread bag clips that have inspired an entire taxonomy complete with Latin names, species classifications, and a community of collectors. Then, we investigate a strange power outage in central Texas, where power poles caught fire after a light drizzle. We unpack the science behind pole-top fires, the "Goldilocks" weather conditions that fuel them, and the surprising technologies being used to inspect and maintain power grids across the world.
