A newly published research study funded the National Institute on Alcohol Abuse and Alcoholism (NIAAA) has identified new genes that may play a role in the overconsumption of alcohol. The report appears in today’s Procedings of the National Academy of Sciences. According to to the NIAAA, grant recipient Dr. Susan E. Bergeson, Ph.D., of the University of Texas (UT) at Austin, and a multi-site team of scientists participating in NIAAA’s Integrative Neuroscience Initiative on Alcoholism (INIA) employed mice that were specially bred to have a high or low preference for alcohol to study gene expression in their brains. Numerous pathways, as well as genes whose functions are currently unknown, may contribute to the genetic predisposition to drink high amounts of alcohol, notes Dr. Bergeson. “Our results will allow us to begin to focus on targets never previously implicated in excessive drinking. For example, genetic studies have shown that chromosome 9 contains genes that may regulate alcohol consumption in mice. Our analyses allowed us to narrow our focus from thousands of genes in that region to twenty.” (Image Credit: BBC)

Back in the ’90s, the golden mussel (Limnoperna fortunei) hitched a ride on ships traveling from Asia to South America. In the past decade and a half, the mussel has proliferated through South America’s river systems, destroying the native habitat and disrupting the operation of power plants and water treatment facilities. This invasive species now threatens the delicate […]
Wendy Chung of the Simons Foundation Autism Research Initiative says that she is constantly asked the same question by parents: “Why does my child have autism?” It’s a question that plagues them whether their child has a severe form of autism, to the point of being non-verbal, or a mild one. “Autism isn’t a single condition. It’s […]
