December 2010 Announces the recipient of an award for online resources in education, Dr. Louisa Stark, who developed two interactive Web sites on genetics.
Presents research findings linking 89 genes to drug abuse and dependence, found using genome-wide association studies, a new technique for identifying genes.
Reports on a study involving researchers who successfully desensitized mice to cocaine by genetically altering their dopamine transporters.
Reports on an animal study suggesting that the manic stage of bipolar disorder promotes signs of drug abuse vulnerability by enhancing sensitivity to rewards, both natural and drug-related.
In a surprising finding, male rats who used cocaine sired male offspring who later exhibited blunted responses to the drug. Researchers determined the cause was an epigenetic alteration.
Reports on the relative influence of genes versus environment on adolescents’ choices that involve delayed gratification.
Describes a literature analysis reporting on the prevalence of people with bipolar disorder who also have a substance use disorder and discusses the genetic link that may contribute to this comorbidity.
Reports on the research underway to identify gene variations associated with nicotine addiction and the interaction of genetic makeup, experiences, and surroundings to addiction.
July 2011 Describes research showing that the combination of prenatal smoking exposure and specific genes increases children’s and adolescent’s risk for behavior problems.
Describes research exploring differences and similarities in the genetic profiles of African-Americans and European-Americans who are heavy smokers.
