Tiny Matters

In this episode of Tiny Show and Tell Us, we explore a listener's experience with peanut allergy immunotherapy — what it is, how the therapy works, and the odd and fascinating history of allergy treatments, including a 19th‑century scientist who shoved grass pollen up his own nose. Then we chat about “reef balls” made of oyster shells and concrete. These mini artificial reefs are being used to restore marine habitats and, in some cases, also hold cremated remains.Check out Simple and Clean here or wherever you listen to podcasts!We need your stories — they're what make these bonus episodes possible!

We want to recommend a new podcast called The Interface. It's the BBC's fiercly informed, fast and funny take on how tech is impacting all of us. We have become regular listeners and hope you enjoy it too!

Monique Rainford, obstetrician and maternal health justice advocate. Deidre Cooper Owens, historian of medicine who uncovers gynecology’s roots in slavery. Alexis Pedrick, science-history storyteller and producer. They trace racist myths about Black bodies, historic medical exploitation, modern pain bias and maternal disparities, and consider midwifery, doulas, and policy as responses.

Chain Reaction is a new podcast from the American Chemical Society that links chemistry’s past to its future, revealing how this ever‑evolving science shapes the world around us, from the materials we use every day to the environment that we depend on. Each episode brings fresh perspectives and personal stories from chemists, engineers, and other scientists, as well as historians who guide us through pivotal moments in chemistry’s history. Together, we’ll uncover chemistry’s surprising connections, explore its interdisciplinary impact, and see how past discoveries set off the breakthroughs of today and the future. Whether you’re a student, an experienced scientist, or simply curious, Chain Reaction will show you how chemistry fits into the bigger picture — and why it matters now more than ever.

In this episode of Tiny Show and Tell Us, we go from nerdy house-party physics to the brutal realities of morning sickness (can you say range!). First, we unpack what 5D data storage is and debate what we’d personally toss into the “Memory of Mankind” salt mine in Austria. Then we tackle a listener’s question about whether science has any updates on what causes severe morning sickness. We need your stories — they're what make these bonus episodes possible!

Monica Piris, a high-altitude expedition physician with years on Everest, and Nathan Hudson-Peacock, an emergency doctor turned expedition medic, share gripping field stories. They cover sudden high-altitude cerebral edema, improvised rescues, what goes into preparing teams, risks beyond altitude like frostbite and infections, and how climate change and remote work reshape medical practice.

In this episode of Tiny Show and Tell Us, we talk about the crafty corvids that steal anti‑bird spikes to build chaotic, spiky nests and “Mitochondrial Eve” — the most recent common maternal ancestor of modern humans. Get ready for stories of sandwich‑stealing gulls, Deboki being held hostage by a peacock, and the Mitochondrial Eve/Y Chromosomal Adam romcom no one asked for.We need your stories — they're what make these bonus episodes possible!

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.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.

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.We need your stories — they're what make these bonus episodes possible!

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.
