In 1986, an encounter changed ocean science forever. Today, on its 40th anniversary, ⁨Radiolab⁩ and ⁨the Science Communication Lab are proud to present THE TINIEST PLANKTON—a new film by ⁨Sharon Shattuck celebrating the discovery of Prochlorococcus! 🦠🌊

On a research cruise off the coast of Africa, Penny Chisholm and her team had an idea to point a flow cytometer at seawater. What looked like background noise in the samples turned out to be the most abundant photosynthetic organism on Earth: a microscopic powerhouse driving our oceans and supplying 20% of global oxygen.

Join scientists Penny Chisholm and Heidi Sosik as they share the inside story behind this remarkable find.
