Epigenetics

Monday, July 11, 2011

Richard Francis discusses the new scientific field of epigenetics, the study of how stress in the environment can impact an individual's physiology so deeply that those biological scars actually can be inherited by the next generations. In Epigenetics: The Ultimate Mystery of Inheritance he explains why researchers believe that epigenetics holds the key to understanding obesity, cancer, Alzheimer's, schizophrenia, autism, and diabetes.

This explains much about the health problems of African Americans… imagine the epigenetic changes the trans-Atlantic boat ride must have caused in the bodies of the abducted let alone the centuries of enslavement and then the decades of Jim Crow… it’s a wonder and testament to our strength as a people that were still here.

Georgina, is hyperemesis gravidarum normal morning sickness or a more extreme version that severely deprives a fetus of nourishment?

Lost a leg? It's more like the Y chromosome lost all *but* a leg!

I know that children of mothers who lived through the Holocaust are definitely deeply affected psychologically. Whether it is genetic or not, I cannot say, but repercussions of this trauma echo on. Children of highly traumatized parents are often affected themselves.

Does the health of childen born from mothers who suffered from Hyperemesis Gravidarum correlate with the Dutch study?

What is the biological mechanism that occur when external factors change the genes?

(That is if I understand what you are talking about)

Please have your guest explain how epigenetics is the difference between your toe nail and your eye.

Epigenetics is not new, its as old as the central dogma of DNA (Richard Dawkins, et al). Dr. Bruce Lipton, author of BIOLOGY OF BELIEF is the contemporary proponent of this theory, and he has the evidence to back it up. Our life, at the micro level (our cells), and the macro (our complete body), is determined more by our relationships with those in our proximity, than with the imprint of the genes we are born with. Take physical longevity, for example: if you are born with 'good genes', but lead an unhealthy lifestyle, you will get chronic degenerative disease much faster as you age. If you are born with 'weak genes', but lead a robust, healthy life, you can extend your longevity beyond any 'date/time' stamp the doctors think you possess.

let's not forget, that this works in a positive direction also. please don't fixate on pathology.
