DNA is a vitally important starting point for life, but it’s how it’s used by cells and organisms that is really important. Epigenetics is a rapidly moving field that has transformed our understanding of how one set of genes can create the masterpiece that is each of us. It’s also leading scientists into unexpected and exciting areas such as new ways to treat disease, understand drug addiction or unravel the lifelong consequences of early childhood trauma.

Nessa Carey is a geneticist and author of The Epigenetics Revolution. She has a degree in Immunology, PhD in Virology, was a post-doctoral researcher in Human Genetics, and a senior lecturer at Imperial College London in Molecular Biology. She’s also spent 10 years in the biotechnology industry and now works in the pharmaceutical sector.

  1. I've been wanting to create a learning center for some time now. In this era of social distancing, I am taking the first steps by beginning it online. The 'Synechism Center for Learning and Dialogue' is now conducting its work from my YouTube channel. It's time. …. Those who understand the differences between synechism and nominalism, triadic versus dyadic thinking, and the terrible fallout to humanity that the misdirected, missing limb of perception has caused (dualism, reductionism, materialism, ontological individualism), need to combine their teaching skills to combat humanity's current direction. Time is of the essence. We need to teach the importance of understanding and respecting 'biological dialogue' (semiosis, dialogism, unity of opposites, 'Being' categories, universes of experience, etc.), and this teaching needs to touch all levels of education and intellect, not just academia. .. Many people have recognized this natural understanding when learning about any one of a handful of historic thinkers (referenced on 'My Freedom from Nominalism' playlist), and my goal is to gather those who recognize this understanding, no matter their source. … We are too spread out in trying to combat nominalism. We would have much better success if we unify our efforts and practice what we preach instead of individualizing and 'naming' this understanding in so many ways that it is confusing for others. … Otherness is key. … The common man and woman are very vulnerable and subject to the forces of a nominalistic culture. If we don't reach them in ways that they can understand, humanity's tragic direction will not change. … You will find the historical background of our dilemma on my 'Discussion' tab. … Thank you.

  2. Fantastic, Love the energy your brought to your book The Epigenetics Revolution"
    I wonder if you can see the link between Epigenetics and Buddhist Karma.
    (They are both very deep matters)
    Any Buddhist's out there pls read this and think….

  3. You should have tried things like hand raising the runty mouse offspring and such. How could the female restrict calories of babies? Probably by making it harder for them to feed. Also how were the females mated, held down, or just put together with the male?

  4. 34:00 all imprinted genes have a female version which wants to get rid of the kid and male version that wants to nourish the kid no matter what, eg. Gene responsible for chrionicvilli implantation in endometrium and gene of prader willi/angelman

  5. Let's summarise. No it isn't a new field.. C.H Waddington was on this in the 1950's and Jean Piaget in the 1970's and 1980's. However the REAL TRUTH is that the phenotype can / has to become hereditarily fixed. This was found in 1974!Therein lies the problem.. the truth goes against flaky neo Darwinism and its refutation of Lamarck. It's all about the environment's ( ie non hereditary) causal affect on gene expression ( the phenotype). Piaget proved in 1974 that the phenotype precedes the genotype. The environment can be considered the internal environment of the organism external to the stem cell and also the external environment external to the organism, and even the social environment external to the cognitive phenotype. So the environment is a REAL controlling factor in the development of the organisms structural or behavioural phenotype. Now you know why and how social engineering works and why we have Public Schools and why we segregate by class etc etc .. The environment really does affect your gene expression (or your evolutionary fitness) as well as hereditary fixing characteristics into your genome for the benefit of your offspring… People who suffer massive trauma, stress and anxiety in their lives often get physiological and psychological symptoms which directly affects their genome and its expression ie schizophrenia, cancer…etc…

  6. Reading her book now after watching this a few months ago! Brilliant and exciting literature! Epigenetics is such a fascinating field! This is telling us how we can affect our future progeny!

  7. re 1:21 … well, scientists did not create life, nor the DNA. Their role is of passive … learners… observers. So, why would scientists get offended by not receiving credit for something they shouldn't get credit? I don't get it.
    well, no, I actually do get it. these are the folks of the highest ego in any given population. Who else names discoveries after themselves? I mean one thing to name an invention that you made. But a discovery? well

    saying that, generally, presentation was good

  8. please tell me it's evolution maybe I'll try harder at buying into this time.. dna code with switches hmm what kinda systems use that kinda programming/. in a few years will they be building bodies from scratch ?

  9. There's one thing I am confused about. So if the histones are wrapped around our genes, and say you become a smoker (but no one in your family tree extending hundreds of years smoked) and the chemical tag is added to the histones to make that gene become 'expressed', does that mean that the 'smoker gene' is predetermined? In other words, will I have a 'smoking gene' by default that is turned off, but will only be turned on if I smoke?

  10. Would a babies/child’s dna receptors be affected/changed by a traumatic birth experience?

    Ie would a more ‘relaxed’, non stressfull/traumatic birth experience have a better outcome for a child later in
    Life?
