Petri Dish

Profane, insane, and 100% primo science, Petri Dish is a no-BS podcast that explores the wildest subjects in modern science with clarity and evil joy. Hosted by Sean Allen, a Nanoparticle/Immunology Researcher, and Nathan Allen, his "screenwriter" brother, Petri Dish fuses hard science with a freewheeling and madcap conversational style. Cannabinoids, Plague, Cats, the dreaded Candiru, and the even more dreaded Covid-19: all these and more are dissected with intellect and irreverence, dropping
