Tiny Matters: Daily Summaries Delivered
by Multitude
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?"

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

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.Check out Simple and Clean here or wherever you listen to podcasts!A transcript and references for this episode can be found at acs.org/tinymatters.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

[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 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?Check out American Medieval here or wherever you listen to podcasts!A transcript and references for this episode can be found at acs.org/tinymatters.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

[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.Find Mischa at mischastanton.com.We need your stories — they're what make these bonus episodes possible!

The Challenger disaster: How a NASA tragedy led to a safer Artemis II
When Artemis II lifted off this past April, marking humanity’s return to the Moon, people across the world were captivated. It was a triumph decades in the making, but also shaped by painful loss due to a toxic organizational culture. In this episode of Tiny Matters, we trace the legacy of the Space Shuttle Challenger disaster on its 40th anniversary, unpacking what went wrong — from brittle O-rings to “normalization of deviance.” We hear firsthand from astronaut Terry Hart, who flew on Challenger less than two years before the accident, and from NASA’s acting Chief of Safety and Mission Assurance, Nathan Vassberg, about how Challenger — and later, Columbia — reshaped the way NASA thinks about risk, and how those lessons were applied to Artemis II. We also hear from Vanessa Bentley, professor of applied ethics who teaches a course dissecting the conflict between managers and engineers that led to the Challenger disaster.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.
