In this episode of The International Book Show, host Makonnen speaks with author Leon Marshall about his book The Hidden Science of Melanin. Leon explores melanin as a vital component of human biology, describing it as a “chemical key to life” and explaining its presence in the brain, immune system, and overall bodily functions.

He breaks down how melanin is produced, the different types, and its roles in areas like movement, protection, fertility, and drug metabolism. The conversation also challenges common misconceptions, including the idea that melanin blocks sunlight.

Leon highlights the research behind his book, which includes over 120 scientific references and vivid illustrations, aimed at making complex science more accessible and relatable.
