Multitude
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 impact our world’s future. New episodes every Wednesday. Tiny Matters is brought to you by the American Chemical Society, a non-profit scientific organization based in Washington, D.C., and is produced by Multitude.

Pig hearts in people: Xenotransplantation's history, promise, and the ethical use of people who are brain-dead in research
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 into another. In the United States, over 100,000 kids and adults are currently on the national transplant waiting list, and every day around 17 people on that list die while waiting. In today's episode, we cover the science and historical research that made Bennett’s transplant possible, and what doctors learned from him that helped the next heart xenotransplant recipient, Lawrence Faucette, live even longer. We also get into some of the ethics conversations surrounding xenotransplantation work — not just questions about the use of animals like pigs and baboons, but experiments with recently deceased, i.e. brain dead, people.Check out Jyoti Madhusoodanan's Undark story, "The Allure and Dangers of Experimenting With Brain-Dead Bodies" here.

Sewage and the Seine: From Mesopotamia messes and the 1858 Great Stink to today's flush toilets and fatbergs
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 other bacteria. And a lot of people are asking, "why is this river so dirty?" In today’s episode, we’re going to get into the interesting history of how people have dealt with sewage, from Mesopotamia times to today, and how the Seine, as well as a river Sam knows well — the Potomac — are trying to clean up their acts. We'll dive into questions like, 'Will it ever be legal to swim in the Potomac?' 'Did Thomas Crapper actually invent the cra... um, toilet?' 'How do you clean up dilapidated old mines that are poisoning a river?' and more.

‘Beef snow,’ sludge, and seafood fraud: How NIST standardizes everything from $1,143 peanut butter to house dust to keep us safe
Standard reference materials — or SRMs — at the National Institute of Standards and Technology (NIST) serve as standards for many food, beverage, health, industrial and other products. There are over a thousand SRMs including peanut butter, house dust, dry cat food, soy milk, blueberries, stainless steel, fertilizer, and a DNA profiling standard. SRMs help make products safer and ensure that consumers are getting what they think they’re getting. But how do they work exactly?In this episode of Tiny Matters, Sam and Deboki cover SRMs that are helping us accurately detect toxic substances like lead and pesticides in our house dust, fight seafood fraud, and keep PFAS out of our meat. Sam also travels to the NIST headquarters outside of Washington, DC to get a behind the scenes tour of how SRMs are made. She even gets a chance to snoop around the warehouse where SRMs are stored.Email us your science stories/factoids/news that you want to share at tinymatters@acs.org for a chance to be featured on Tiny Show and Tell Us!Tiny Matters has a YouTube channel!
