Why are 95% of people who live to 110 women? You're as old as your stem cells Human super centenarians share at least one thing in common--over 95 percent are women. Scientists have long observed differences between the sexes when it comes to aging, but there is no clear explanation for why females live longer. In a discussion of what we know about stem cell behavior and sex, researchers argue that it's time to look at differences in regenerative decline between men and women..

One night of partial sleep deprivation activates gene expression patterns in peripheral blood mononuclear cells (PBMCs) consistent with increasing accumulation of damage that initiates cell cycle arrest.
