Science shapes every facet of our lives, but so much of its influence is overlooked or buried in the past. Tiny Matters is an award-winning science podcast about the small science of big things. From the microbes behind deadly diseases to the molecules informing our search for extraterrestrial life, hosts and former scientists Sam Jones and Deboki Chakravarti embrace the awe and messiness of science and its significance both today and in the past, asking questions like, "how was IVF invented?," "what do glaciers tell us about Earth’s ancient past?," and "why is smallpox the only human infectious disease we’ve eradicated?"

Tiny Matters is created by the American Chemical Society, a non-profit scientific organization based in Washington, D.C., and is produced by Multitude. New episodes every Wednesday, wherever you listen to podcasts.

    [BONUS] The ‘Tyrant Lizard Queen’ and how evolution shaped our anxious brains: Tiny Show and Tell Us #58
    Oct 21 2026

    Why does your brain sometimes react to a stressful meeting or traffic jam like you’re being hunted by a lion on the savannah? In this episode of Tiny Show and Tell Us, we explore the evolutionary roots of anxiety, why our internal alarm system sometimes misfires, and how treatments can help some people. Then paleontologist and author Riley Black joins the show to talk about her new book Tyrant Lizard Queen: The Love, Life, and Terror of Earth’s Greatest Carnivore. She shares why T. rex is a much more complicated dinosaur than the movie monster we’re used to seeing. We hear about how T. rex grew, hunted, weathered dramatic environmental changes, and fit into her ecosystem.

    [BONUS] Decoding dinosaur colors and the failure of postpartum care: Tiny Show and Tell Us #57
    Oct 7 2026

    In this episode of Tiny Show and Tell Us, a listener asks why maternal mortality rates in countries like the U.S. and Canada have risen while many other wealthy nations have seen them plateau or even decrease. We talk about postpartum health, racial disparities, access to care, and why support after birth can be just as important as care during pregnancy and delivery. Then we switch gears and discuss how we know the colors of some dinosaurs. The answer lies in tiny fossilized structures called melanosomes, which allowed researchers to reconstruct some of the colors of dinosaurs.
