It only gets better from here...

The following is a comment to this article on the new "cosmecuticals" industry that is emerging due to advances made from the sequencing of the genome and the amazing discoveries of stem cells in the last few years. Early this year a paper was published that isolated key genes in the expression of skin tissues that contain both sebaceous (oil) and perspiration (sweat) glands. Last year a method was published that allowed the genetic mutation changes in tissue pathology (in that case two cancers) to be tracked down to the number of changes (the 1 mutation per 15 cigarettes paper) tie these methods together and you have a recipe for finding differentiating pathological and normal development in tissues. We already know that the genetic code is amazingly dense but most of it consists of "non coding regions", now the story is coming clear....it is a hierarchical code. Most of it is devoted to developmental pathway ('how long to grow or release it') as opposed...
