    [BONUS] Dangerously tiny frequencies, endometriosis tests, and cookies made from ... plastic?: Tiny Show and Tell Us #54

    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.

    Giant viruses: How these amoeba-infecting behemoths are rewriting the rules of virology

    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.

    [BONUS] Fairy tale evolution and the 400(ish) year old elusive Greenland shark: Tiny Show and Tell Us #53

    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.

    From cow’s milk to blood banks: The surprising evolution of blood transfusions

    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.

    [BONUS] Bread clip taxonomy and power poles on fire: Tiny Show and Tell Us #52

    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.

    Placebo: Why ‘fake’ treatments can have real power

    A sugar pill shouldn't work as well as a real drug ... except sometimes it does. In this episode, we explore the fascinating science of the placebo effect and how expectations can shape biological outcomes. From open-label placebos and AI healthcare chatbots to the nocebo effect, we unpack what scientists know, what they still don't understand, and why the placebo response is still largely mysterious.

    [BONUS] A pathology lab, a sausage duel, and the fascinating lives of yeast: Tiny Show and Tell Us #51

    In this episode of Tiny Matters, a listener who works in a pathology lab explains how even the ickiest specimens become ho-hum with time, sending Sam and Deboki down a rabbit hole of pathology history and the bizarre life of Rudolf Virchow, the “father of pathology” who was also rumored to have brought worm-filled sausages to a duel. Then, a listener's sourdough experiments spark a conversation about yeast and how these microscopic organisms are the chemists behind tasty bread, beer, wine, and more.

    Fireworks over millennia: From battlefields and royal displays to sustainable spectacles

    In medieval Europe, people who worked with early cannons and gunpowder were viewed as untrustworthy, boorish outsiders. But just a few centuries later, as they began creating elaborate fireworks displays for royalty, they went from outcasts to artists. From black powder to modern low-smoke pyrotechnics, in this episode of Tiny Matters we look at the chemistry, engineering, and artistry behind one of humanity's favorite forms of celebration. We also learn how scientists are reinventing pyrotechnics with cleaner-burning compounds that deliver brighter colors and fewer emissions. And check out this video from our friends at Headline Science to get a behind the scenes tour of the Science History Institute’s new exhibit: Flash! Bang! Boom! A History of Fireworks.

    [BONUS] The ‘elite neutralizers’ immune to HIV and why galaxies ‘FART’: Tiny Show and Tell Us #50

    This week on Tiny Show and Tell Us, a listener introduces us to "FARTs" — a silly acronym for galactic gas outflows — and sends us down a rabbit hole of dying stars and recycled cosmic gas in the early universe. Then we discuss the decades-long search for broadly neutralizing antibodies (bNAbs) that can target many HIV strains at once. One bNAb that looks promising is in clinical trials right now!

    Collisions in space: Satellites, space debris, and the quest to clean up Earth's orbit

    We tend to think of space as vast and mostly empty, yet the region just above Earth is far from it. In this episode, we explore the surprising congestion of low Earth orbit, where tens of thousands of satellites and millions of pieces of debris are hurtling around at incredible speeds. From a major satellite collision in 2009 to the looming threat of the Kessler Effect — where Earth’s orbit becomes so densely packed that collisions set off an unstoppable chain reaction — we unpack how even tiny fragments can cause massive damage to spacecraft, disrupt critical services, and potentially put astronauts and even us Earth dwellers at risk. We talk with scientists about creative solutions that could help tackle this growing problem, including space lasers, and we ask an important question: who is responsible for keeping space clean?

    [BONUS] A nitrogen asphyxiation disaster and why ears are incredible: Tiny Show and Tell Us #49

    In this episode of Tiny Show and Tell Us, we unpack a tragic NASA accident in 1981 when technicians, preparing for the maiden voyage of Space Shuttle Columbia, were accidentally poisoned by nitrogen gas. Then guest Mischa Stanton takes us deep inside the human ear. We talk about how vibrations turn into thoughts via the cochlea and basilar membrane and dive into the fascinating world of logarithmic perception.
