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 is a hierarchical code. Most of it is devoted to developmental pathway ('how long to grow or release it') as opposed…

Emotion no longer has to be our guide?

Two recent discussions I've engaged in on Facebook have elicited more thought on the subject of how the human brain ties together emotion to memory. A study released recently showed that an emotional component could be untied or subtracted from the associated sensory experience or memory under current retrieval if a stimulus is provided at a given time. This discovery hints at some amazing possibilities for how the human brain works and helps point to a possible hypothesis for the purpose of emotion in the evolutionary history of the brain.

The new frontier of brain science

We know today loosely that the neocortex is responsible for processing and relating sensory input (between adjacent senses) we know that "adjacent" is more than an abstract categorization of their hierarchy in the mind but is quite literal, when flattened out the surface consists of patches of cells devoted to processing various types of sensory input in several layers (5 or 6)...where their edged touc…
