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. Every Wednesday, hosts and former scientists Sam Jones and Deboki Chakravarti cover topics from infectious disease to the search for extraterrestrial life, embracing the awe and messiness of science today and throughout history, 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?"
