Too little or too much sleep might be hurting you more than you think.
Epigenetic aging clocks use DNA methylation patterns to measure biological age and predict health risks across human tissues.
For nearly a century, scientists have watched underfed lab animals outlive their well-fed counterparts. Worms, flies, mice, ...
Landmark review analyzes 41 human studies to identify which interventions have been shown to slow next-generation epigenetic ...

The immune system acts as a critical sentinel of organismal aging, integrating the sensing of physiological states with the execution of defense and clearance functions. Immunosenescence not only ...
A team of international researchers has developed a new biological age "clock" that estimates how well someone is aging, not just how "old" they or their various organs might be. The IC Clock, which ...
Universal” biological signatures of aging shared across different mammalian species—including humans—could offer new clues to ...
Molecular clocks that can provide accurate estimates of both molecular age and lifespan across multiple mammalian species and ...
Aging is a complex process, and precisely measuring how the human body declines has long been a challenge. Two people of the same chronological age can have very different health trajectories.
