Matters Microbial #82: Melanin, Fungi, and Global Warming

Today, the impressive Dr. Arturo Casadevall of Johns Hopkins University returns to the podcast to discuss how fungal disease is a looming threat on our warming planet, and how these organisms can use pigmentation to adapt to human-associated environments . . . and increase their chances of causing disease.
