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 from the American Chemical Society about tiny things — from molecules to microbes — that have a big and often surprising impact on society, past and present. From deadly diseases to forensic toxicology to the search for extraterrestrial life, hosts and former scientists Sam Jones and Deboki Chakravarti embrace the awe and messiness of science and its significance, 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?" New episodes every Wednesday wherever you listen to podcasts.

    From ancient grain mills to massive offshore turbines: Why wind energy was — and still is — a big deal

    For over a thousand years, humans have been harnessing wind energy. It may have begun with small, grain‑grinding windmills in ancient Persia, but today you might spot Hoover‑Dam‑sized offshore turbines as you drive along the east coast. How did we get here? In this episode of Tiny Matters, we explore the first electric wind turbines built in the late 1800s, how government policies in the 1970s and ’80s shaped the modern wind industry, and why giant offshore wind farms are suddenly in the news. We also clear up misinformation stemming from a Hollywood blockbuster as well as what we know about the impact of wind farms on whales, birds and bats.

    [BONUS] Dandelion rubber tires and a fentanyl vaccine: Tiny Show and Tell Us #40

    In this episode of Tiny Show and Tell Us, we explore a listener’s tip about a new source of tire rubber — the Russian dandelion — and the science behind what makes it such an incredible and sustainable source of natural latex rubber. Then we answer a listener’s question about a vaccine for fentanyl that will stop the drug from reaching the brain, preventing overdose.

    The history of clinical trials: From fake exorcisms to testing today

    In 1599, a family in a small French town claimed that their daughter was possessed by a demon called Beelzebub and, despite daily exorcisms, the demon possessing this woman was staying put. So France’s Henri IV set up a royal commission that would try something a little different. The woman would still receive exorcisms, complete with the normal exorcism accoutrements, but with a catch. The priest wouldn’t actually be Catholic, the water in the vessel would be ordinary water, and the Latin used wouldn’t be religious — it would be from Virgil’s famous poem Aeneid. That's because this wasn't actually an exorcism. It was an experiment built on a deceptively simple tool that scientists and doctors still use today to study new medical treatments: a placebo. In this episode, we explore the surprising origins and evolution of one of modern medicine’s most important tools: the clinical trial. We follow the development of experimental design across centuries to modern day randomized controlled trials and the debates about their limitations, trying to answer the question, “How do we know whether a treatment truly works?” Send us your science facts, news, or other stories for a chance to be featured on an upcoming Tiny Show and Tell Us bonus episode.

    [BONUS] Bat periods and toxins from fungi: Tiny Show and Tell Us #39

    In this episode of Tiny Show and Tell Us, we learn that humans aren’t the only mammals who menstruate. We explore the fulvous fruit bat’s 33‑day cycle, how reproductive biology differs across species, and why scientists still don’t fully understand why menstruation evolved in the first place. Then we take a deep dive into the world of mycotoxins: dangerous compounds produced by fungi. We cover how these toxins form, why they’re so hard to eliminate, and risks they pose to agriculture, livestock, and human health.

    The iron lung: How a hulking metal tube became the first machine to keep humans alive

    It’s no exaggeration to say that polio shaped modern medicine. Before a vaccine was available, polio outbreaks left thousands of people paralyzed, with some unable to breathe. But, in 1928, the development of the iron lung meant that, for the first time, humans could rely on a machine to stay alive. In this episode, we trace the rise of polio in the early 20th century, the science behind the virus, and the race to save lives. From early resuscitation experiments to the unexpected inspiration behind the iron lung, we uncover the innovation, ethical dilemmas, and human stories that defined this era, hearing from two people whose early childhoods and families were dramatically shaped by the disease.  Send us your science facts, news, or other stories for a chance to be featured on an upcoming Tiny Show and Tell Us bonus episode.

    [BONUS] The woman who mapped the Milky Way and a toxic evolutionary showdown: Tiny Show and Tell Us #38

    In this episode of Tiny Show and Tell Us, we kick things off with a quick shout-out to a listener who started flossing thanks to a previous episode. Then we dive into the hidden history of the women “computers” at Harvard Observatory, including Henrietta Leavitt, who laid the foundation for modern astronomy with her groundbreaking discoveries including calculating the size of the Milky Way. Then we discuss the co-evolutionary arms race between passion vines and Heliconius butterflies, which includes fake eggs, toxic fruit, and impaled caterpillars.
