South Florida’s tropical fruits are not just a glamorous little collection of produce that happens to like warm weather. They are really a lesson in how growing something and growing it well are not at all the same thing. Avocado, mango, lychee, longan, mamey, banana, passionfruit, and dragonfruit all bring their own baggage, frankly, whether that is drainage issues, flowering quirks, storm damage, trellising, pests, diseases, or the awkward little question of whether anyone is actually going to buy enough of it to make the whole thing worthwhile. And that is what makes South Florida so interesting. It is not just warm, and therefore magical. It is warm in a way that opens the door, but then everything else — the soil, the weather, the crop biology, the grower, and the market — has to decide what happens next.

In this episode of 4Ps, Dr. Kate Martin takes a closer look at cockroaches, the insects people think they already understand. From their strange biology and surprising diversity to the major pest species found around human spaces, this episode explores what cockroaches actually are, how they succeed so well alongside us, and why their reputation only tells part of the story. Unsettling, scientifically fascinating, and unfortunately very good at being cockroaches.

In this episode of 4Ps: Plants, Pests, Parasites and People, Dr. Kate Martin explores Cauliflower mosaic virus (CaMV)—a plant virus most people have never heard of, but one that quietly shaped modern plant science. From haunted-looking brassica leaves and aphid transmission to the famous CaMV 35S promoter, this is the story of how a crop disease became one of the most widely used molecular tools in plant biology. It’s a look at viruses, agriculture, and biotechnology through one surprisingly influential little pathogen.
