Dear Tipsters,
There is a fascinating article in the May 2007 issue of Nature Reviews
Neuroscience about how epigenetics might explain a variety of
psychiatric disorders, including depression schizophrenia, and drug
addiction.
If you haven't heard of it before, epigenetics is a scientific
discipline that has been emerging over the past decade or so that
attempts to model the regulation of gene expression -- i.e., of the many
genes in an organism's DNA, many are never expressed, and apparently
identical genes in two different organisms of the same species can be
expressed in different ways and at different times. Environmental
factors seem to control which genes are expressed and the manner in
which they are expressed. How precisely this works is what the field of
epigenetics attempts to address.
One can get access to the article at

register on the Nature site to get it).
