Key Takeaways High neuronal activity levels have been linked to a shorter lifespan.Lower levels of brain activity have been, conversely, associated with increased longevity.This association has been confirmed in several different organisms including worms, mice, and humans.The REST gene is a major regulator of neuronal excitability that prevents excess activity in the neurons. Evidence indicates that people who managed to reach the age of 85 and beyond have a much more active REST gene than…

Key Takeaways General stress and socio-economic issues increase one’s risk for many diseases and mortality. Scientists don’t know the exact mechanism yetOne possible explanation could be cellular aging due to stress, with resulting impairment in cell and tissue functionIn this animal study, mice subjected to lifelong chronic psychosocial stress developed several health issues associated with cell aging. This association suggests that stress may, indeed, increase the risk of disease and reduce life expectancy Actions to…

Key Takeaways Your genetic information is stored in genes, which are bundled tightly into chromosomes that are stored in every cell’s nucleus. The end fragments of each chromosome are called telomeres. Their primary function is to protect the genetic information in the chromosomes from instability.With each cell division, part of the telomere is lost. When a telomere’s length becomes critically short, its cell dies via apoptosis (programmed cell death)There is a clear link between short…
