Obesity in Offsprings Linked To Endocrine Disrupting Compounds

Fetal Exposure To PVC Plastic Chemical Linked To Obesity In Offspring.  Science Daily.  January 15, 2013.

TBT, tributyltin, is used in PVC plastic and marine hull paint.  According to Dr. Bruce Blumberg, UC Irvine professor of pharmaceutical sciences and developmental & cell biology, TBT is an obesogen.   This class of chemicals acts in part by modifying mesenchymal stem cells during development, giving them a propensity to become fat cells.  While the study focused on mice, there perhaps could be implications for children and pregnant women.

Developmental Stability the Key to Intelligence?

If Smart is the Norm, Stupidity Gets More Interesting by David Dobbs.  The New York Times.  October 23, 2012.

Since scientists are having difficulty in finding the specific genetic keys to intelligence, they are looking elsewhere.  By looking at the mutations we carry and their relationship to developmental stability, the accuracy with which the genetic design is built, they are beginning to discern an association between bodily symmetry and intelligence.  This article is largely based upon the ideas of Kevin Mitchell, a developmental neurogeneticists at Trinity College Dublin.
