A scientist from Budapest who immigrated to the US in the 1930s. A beloved and common pet store fish. And a researcher looking at genes that suppress the growth of cancerous tumors. On this episode of The Show About Science, these three worlds serendipitously collide to lead to a discovery that would help us understand one of the most important things in human history. Joining Nate on the show are Keith Cheng, the Principal Investigator of the Cheng Lab at the Penn State College of Medicine, and Máté Varga, a professor at Eötvös Loránd University in the Department of Genetics.
