Genes amplify the stress of harsh environments for some children, and magnify the advantage of supportive environments for other children, according to a study that's one of the first to document how genes interacting with social environments affect biomarkers of stress. The study used telomere length as a marker of stress. Found at the ends of chromosomes, telomeres generally shorten with age, and when individuals are exposed to disease and chronic stress, including the stress of living in a disadvantaged environment.
