Tiny Matters

Science shapes every part of our lives, but so much of its influence is overlooked or buried in the past. Tiny Matters is an award-winning podcast about tiny things — from molecules to microbes — that have a big and often surprising impact on society. 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 place in history and today, and how it could

*A disclaimer that there will be discussions of self harm in this episode* In 2003, Chris Nowinski found himself in a WWE wrestling ring, concussed and not remembering where he was or how he was supposed to finish the match. This would be a pivotal moment not just in his life but for an entire field of research on a neurodegenerative disease long known to exist but poorly defined and even censored: chronic traumatic encephalopathy or CTE. There’s evidence that people knew about CTE — which we...

Tiny Matters ·

2024/08/21

In the early hours of January 7, 2022, David Bennett was out of options. At just 57 years old, he was bedridden, on life support, and in desperate need of a heart transplant for which he was ineligible. Yet Bennett would go on to live for two more months — not with a human heart, but with a heart from a pig. David Bennett was the first case of a pig heart being transplanted into a human, an example of xenotransplantation — when the cells, tissues or organs from one species are transplanted in...

In this episode of Tiny Show and Tell Us, we cover the recent discovery of a new (relatively speaking, more like 100 million year old) organelle called a nitroplast that could revolutionize agriculture. Then we embark on a highly entertaining journey of 1930s chemistry poetry, sometimes written by inebriated chemists, and track down a rare and stunning Chemical Map of North America. Check out the map in this YouTube short and this Instagram post. We need your stories — they're what make these...

You might be familiar with plant-based alternatives to animal products — things like the Impossible Burger or Beyond Meat. And maybe you’ve heard of places trying to grow fish or meat cells in a dish to make sushi or steak without a fish or cow. But in today’s episode we’ll cover an old technology that’s bringing us some new foods: precision fermentation. With precision fermentation, many everyday products including dairy-free milk, insulin, and the collagen in lotions are now being made by m...

Send us a Text Message.The opening ceremony of the 2024 Summer Olympics is two short days away. As over 10,000 athletes gather in Paris, France, anticipation builds. But that anticipation is not just for the next 19 days of fierce competition, it’s also for the Seine. The Seine River is set to host events including the 10 kilometer marathon swim and the triathlon, but as the Games approached, much of the testing showed that the Seine was still teeming with dangerous levels of E. coli and othe...

Send us a Text Message.This summer is a sports fan’s dream! Beyond some major soccer tournaments, Paris 2024 kicks off at the end of July. If you think about it, sports are science in motion, which means that buried in incredible athletic feats is a lot of data about how athlete bodies are using and responding to chemistry, biology and physics. That data is helping scientists design new or better tools for athletes. Today, in honor of this very sporty summer, Sam and Deboki delve into how sci...

Bogoslof had been quiet for 24 years, and there wasn’t any equipment on it that scientists could use to track its eruptions. But over the next 8 months, scientists were able to track at least 70 eruptions from Bogoslof, and they did so using something you might not expect: sound.In this episode of Tiny Matters, we’ll cover what sound can tell us about events as big as volcanoes a...
