Genetics, environment, and smoking in pregnancy

A study in the January issue of Developmental Psychology examined the long-term effect of prenatal exposure to tobacco. This project was unique in that the researchers also considered the expression of genes affecting the dopamine (a neurotransmitter) system in the brain. The researchers asked preschoolers to complete a task that required “executive control;” the executive…

Genes and delinquent friends

Criminology researchers at Florida State University have found a possible genetic link to delinquent peer association among adolescent boys. Professor Kevin Beaver collected information about family friends and DNA of over 1800 boys in middle and high schools. They linked a variation in the Dopamine Transporter gene to affiliation with delinquent peers. However, the connection…

Yoga and meditation at the cellular level

PLoS ONE published an article today comparing long-term meditation and yoga practitioners to a group of controls and a group who had taken an 8-week relaxation training course. The researchers found differences in the expression of over 2200 genes, some of which affected cellular metabolism and response to oxidative stress in the long- and short-term…
