Emma Stoye presents this month’s podcast about immunology professor Daniel Davis’s latest book – The Beautiful Cure. The book explores the history of immunology, along with insights from the author’s career and findings from his recent research. As a leader in the field of immunology, Davis breaks down the various factors that can affect the human immune system, explains how complex a thing it is, and goes on to explore how sensitive it is to things like sleep, stress, age and even our state-of-mind.
