Epigenetics are a complex set up chemicals that surround a gene and tell it when to express itself or go dormant. In this 12-part lecture series, Dr Mykura explores the science and controversy of epigenetics study. She discusses how epigenetics applies to the formation of a fetus, how it responds to external and internal environment. She explains the importance of the gut biome and how epigenetics play out in autoimmune diseases. She ends the series by tackling the question as to whether epigenetic states can be passed from parent to child.
Dr. Mykura presents this fairly technical topic with the charisma and energy of a TED talker. She is fond of enthusiastic hyperbole, like "This is the most amazing process in the history of human biology". This makes her lectures very engaging despite the density of scientific terminology. Throughout the lectures I kept reminding myself, that, of course, things like exercise, stress, and diet change our body's makeup. I just had never thought about how that worked before, and now I feel like I have a better sense of what that process looks like. I enjoyed her creative metaphors to describe difficult concepts, like how a methylated chromosome looks like a tangled ball of string. My favorite fact from the series is that, since a woman's eggs are formed while she is a fetus in her mother's womb, parts of us have been around much longer than we think. That means part of me was first formed in 1935! (6 hours, 2023)
