Radio Review: The Secrets Inside Your Cells - Epigenetics, Trauma and Ancestry

08 May 2017 - by Dr Avi Lerner

The Human Genome Project, completed in April 2003, greatly improved our ability to study human health and disease. It also provided a deeper insight into our history and evolution as a species. Yet a recent episode of the 'Science Friction' radio show, presented by Natasha Mitchell on Australia’s ABC Radio, delved further into these fascinating topics through the lens of the new and emerging field of epigenetics.
