A new study has used aging trajectories of various cell types to predict diseases such as Alzheimer’s and lung cancer [1]. This expands on previous research into organ-specific aging. Age is more than one number Gone are the days when aging was assumed to be happening uniformly across every tissue at once. Today, we know...

A new study links accelerated aging to early-onset solid cancers, while showing that this gap is becoming wider with each new generation [1]. Why do more young people get cancer? While life expectancy has been on the rise for decades (though it has slowed in recent years), counterintuitively, early-onset cancer is becoming more common. Cancers...

A paper in Cell Genomics has described how age-related systemic inflammation (inflammaging) is related to epigenetic aging as measured by four established clocks. Tying together two well-known aspects of aging Chronic InflammationChronic inflammation refers to a persistent, low-grade buzz of immune activity that settles into the body without the drama of an infection or obvious...

A new study reported an association between having more problematic people in close networks and increased biological aging [1]. A look into the dark side Social connection has been discussed as a factor essential for well-being, reduced epigenetic aging, and inflammatory signaling [2, 3]. However, the dark side of social connections, relationships that are toxic...

In Aging Cell, researchers have published their surprising findings that epigenetic clocks are not significantly related to most measurements of metabolic health after weight loss interventions. The utility of clocks What Are Epigenetic ClocksAn epigenetic clock is a biochemical test that uses DNA methylation levels and accumulation of methyl groups on DNA to determine biological...

A new study has found that professional soccer players experience a drop in their biological age after a match, as measured by biomarkers assessed with state-of-the-art methylation clocks [1]. We asked Dr. Steve Horvath, the study’s co-author, to comment. Clocks, stress, and exercise Epigenetic clocks have become extremely popular in the longevity field, both as...
