4Ps

4Ps: Plants, Pests, Parasites & People is a story-driven science podcast hosted by Dr. Kate Martin that uses four rotating lenses—plants, the things that eat them, the diseases that follow, and the people caught in the middle—to answer one big question: how did we get to where we are? From plant domestication and medicinal plants to bed bugs, wheat stem rust, Mormon cricket swarms, and even alchemy in the age of plague, each episode connects biology to our agricultural and urban history—with clear science, sharp storytelling, and the occasional “wait… that explains a lot.”
