An in-depth study charts the genetics involved in the shortening of life in response to mood and stress.
A team from Indiana University School of Medicine and the Scripps Research Institute, CA, conducted a multifaceted project investigating the genetic basis of premature aging in response to stress and psychiatric illness.
Using human participants and Caenorhabditis elegans, one of planet Earth's most-studied worms, the researchers delved into this intractable question.
They managed to identify a raft of genes that seem to control the impact of mood and stress responses on the longevity of an organism.
