[Summary] The book called "The Epigenetics Revolution,” by Nessa Carey offers an overview of the field of epigenetics, which explores how environmental factors can influence the way genes are expressed without changing the underlying DNA sequence. The source explores the impact of epigenetics on human health, including cancer, aging, and mental health. It also discusses the history of the field, highlighting the contributions of key scientists who helped shape our understanding of epigenetics, as well as the potential implications for therapeutic interventions and new drug development.
