Researchers from several institutions, including, UCLA, Boston University, Stanford University and the Institute for Aging Research at Hebrew SeniorLife, analyzed blood samples from nearly 10,000 people to find that genetic markers in the gene responsible for keeping telomeres (tips of chromosomes) youthfully longer, did not translate into a younger biologic age as measured by changes in proteins coating the DNA.
DNA methylation age is a biomarker of chronological age and predicts lifespan, but its underlying molecular mechan...

Read MoreResearchers uncover the link between protein aggregation, aging. Early in evolution, sugar intake and the regulation of life span were linked with each other. The hormone insulin is crucial here. It reduces blood sugar levels by binding to its receptor on the cell surface. However, many processes for stress management and survival are shut down at the same time. When there is a good supply of food, they appear unnecessary to the organism, although this reduces life expectancy over the long term. The insulin receptor thus acts like a brake on life expectancy...
