Factors may prevent postpartum smoking relapseEventhough a number of women quit smoking during pregnancy to protect their unborn children from the effects of cigarettes, half of them resume the habit within a few months of giving birth.
By shedding light on the factors that enable the other half to put down that cigarette for good, a study by scientists at the University of North Carolina at Chapel Hill could lead to programs designed to help women quit and stay quit.

Alcohol consumption can cause too much cell deathThe initial signs of fetal alcohol syndrome are slight but classic: facial malformations such as a flat and high upper lip, small eye openings and a short nose.
Scientists want to know if those facial clues can help them figure out how much alcohol it takes during what point in development to cause these and other lifelong problems.
