A study of over 6,000 mothers and their newborn children—one of the largest studies of its kind—solidifies the evidence that smoking cigarettes while pregnant chemically modifies a fetus' DNA, mirroring patterns seen in adult smokers. The researchers also identify new development-related genes affected by smoking, suggesting a potential explanation for the link between smoking during pregnancy and health complications in children. http://medicalxpress.com/news/2016-03-mom-fetal-dna.html Paper: http://www.cell.com/ajhg/fulltext/S0002-9297(16)00070-7
