Tristram Wyatt

In this fascinating discussion, Tristram Wyatt, a chemical communication expert from Oxford, Jane Hurst, a mammalian scent specialist from Liverpool, and Francis Ratnieks, a honeybee behavior authority from Sussex, explore the intricate world of pheromones. They reveal how these invisible chemical signals guide animal behavior, from honeybees’ alarm signals to rabbits' milk scents influencing neonatal learning. The evolution, diversity, and even applications in pest control of pheromones are also highlighted, showcasing their crucial role in the animal kingdom.

Join dermatologist Dr. Madalyn Nguyen, biological anthropologist Dr. Kara Hoover, author Katherine Ashenburg, and pheromone expert Dr. Tristram Wyatt as they unravel the mysteries behind body odor. They delve into the cultural history of hygiene, revealing Europe's historical fear of washing. The conversation shifts to the science of body odor, exploring bacteria's roles and genetic factors. Discover how natural scents may play a surprising role in attraction and communication, and learn why some might not smell at all!

Melvyn Bragg and guests discuss how members of the same species send each other invisible chemical signals to influence the way they behave. Pheromones are used by species across the animal kingdom in a variety of ways, such as laying trails to be followed, to raise the alarm, to scatter from predators, to signal dominance and to enhance attractiveness and, in honey bees, even direct development into queen or worker. The image above is of male and female ladybirds that have clustered together in response to pheromones.
