Epigenetics - how does it work?: Bruce Lipton explains how your thoughts, and the thoughts of those around you, can directly influence the state of your health.

Epigenetics: from nucleosomes to gene expression: This is a short stop motion video done for a school project on the topic of epigenetics. It provides a brief overview of how nucleosomes become chromatins and how chromatins form a chromosome. From there the video provides a simple look at how chromosomes from identical twins can be affected by methylation, thereby affecting gene expression.

Epigenetics of identical twins: Why do the physical characteristics of identical twins diverge as they age? Follow the interaction of the environment and the genome in a pair of twins over time.

Genetic/Epigenetic modeling of male lupus risk: Women develop lupus nine times more often than men. Research implicates hormones and having two X chromosomes as risk factors for women. However, little is known about why men get lupus. Dr. Bruce Richardson of the University of Michigan has received a Lupus Foundation of America national research grant to study lupus in men. In this video, Dr. Richardson describes his research project and his hypothesis regarding the role epigenetics plays in the development of lupus in males.

The epigenome at a glance: The genome dynamically interacts with the environment as chemical switches that regulate gene expression receive cues from stress, diet, behavior, toxins and other factors. Epigenetics is the study of these reactions and the factors that influence them.

The Ghost In Your Genes: Epigenetics adds a whole new layer to genes beyond the DNA. It proposes a control system of 'switches' that turn genes on or off and suggests that things people experience, like nutrition and stress, can control these switches and cause heritable effects in humans.

Gay twins and the science of epigenetics: What has Science discovered so far about the question over Homosexuality and its inheritable biologic or lifestyle choice debate? Is being Gay a choice? Or are people born Gay? Nature or Nurture?
