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. "Our findings suggest that an individual's genetic architecture moderates the magnitude of the response to external stimuli—but it is the environment that determines the direction" says Colter Mitchell, lead author of...

The long and the short of telomeres In captivity, grey parrots are often kept in social isolation, which can have detrimental effects on their health and wellbeing. So far there have not been any studies on the effects of long term social isolation from conspecifics on cellular aging. Telomeres shorten with each cell division, and once a critical length is reached, cells are unable to divide further (a stage known as 'replicative senescence'). Although cellular senescence is a useful...

Results help explain puzzling features of 'dot chromosome' In previous research, UC Berkeley scientists Beatriz Vicoso, Ph.D., and Doris Bachtrog, Ph.D., determined that genes on the so-called "dot chromosome," or fourth chromosome, of the fruit fly Drosophilia melanogaster are X-linked in three other related fly species. These and other findings revealed that the fruit fly's "dot chromosome" had descended from a differentiated X chromosome and suggests that several of the chromosome's...

University of Helsinki Researchers from the University of Helsinki analyzed thoroughly the commonly occurring genetic variation in chromosome X, one of the two sex-determining chromosomes, in almost 25,000 Northern European individuals with diverse health-related information available. The aim of the study was to find genetic factors that could explain individual differences in several traits, including BMI, height, blood pressure and lipid levels. In addition, the researchers also...

UMD-led study is first to link racism-related factors and cellular age A new study reveals that racism may impact aging at the cellular level. Researchers found signs of accelerated aging in African American men, ages reporting high levels of racial discrimination and who had internalized anti-Black attitudes. Findings from the study, which is the first to link racism-related factors and biological aging, are published in the American Journal of Preventive Medicine. Racial disparities...

[ Watch the Video: Will Beer Or Coffee Contribute To Your Aging? ] Alan McStravick for redOrbit.com - Your Universe Online Each time our cells replicate in our bodies, the end points of chromosomal DNA - known as telomeres - copy themselves to the new cell, shortening with each subsequent copy until they can no longer keep the cell viable, resulting in its eventual death. However, a group of researchers from Tel Aviv University’s (TAU) Department of Molecular Microbiology and...

Aging Biomarker, Telomere Length, Evaluated in Post-Bariatric Surgery Patients ATLANTA, Nov. 15, 2013 /PRNewswire-USNewswire/ -- Researchers have identified a connection between surgical weight loss and the aging biomarker, the telomere, a DNA sequence found on the end of chromosomes. According to a study presented at The Obesity Society (TOS) Annual Meeting at ObesityWeek(SM) 2013, "Does Gastric Bypass Influence Aging?" weight loss following bariatric surgery was associated with...
