Pollution, disease, and climate change are pushing the limits of what coral reefs can withstand. But, despite those harsh conditions, some corals are thriving. Scientists are trying to understand how that's possible, and what they're learning could save these incredible ecosystems from extinction. Episode transcripts at acs.org/tinymatters

We had a vaccine for COVID-19 within a year of identifying the virus that causes it, yet still don’t have one for HIV after 40 years of research. Why is that? On this week’s episode, Sam and Deboki cover HIV’s history and spread, how it causes AIDS, and the tiny things it does that have allowed it to evade potential vaccines for decades.

This week on Tiny Matters, we’re talking about dinosaurs: the ancient beasts that died off 65 million years ago but whose remains still captivate us today. Fossils are helping scientists piece together how dinos and other extinct creatures looked and behaved. That info isn’t just inspiring movies like Jurassic Park—it’s helping researchers predict Earth’s future and could even lead to more sustainable tech. Episode transcripts at acs.org/tinymatters

Tiny Matters is a science podcast about things small in size but big in impact. 

Every other Wednesday, join hosts Sam Jones and Deboki Chakravarti as they unpack the little stuff that makes the big stuff in our world — both good and bad — possible, tackling questions like, “What is a memory?” "Is sugar actually addictive?" and "Why don't we have an HIV vaccine?"
