An integrative study of five biological clocks in somatic and mental health indicate that one's biological age is best reflected by combining aging measures from multiple cellular levels.

Deep learning on fundus images provides a non-invasive, short time-scale biological aging clock that successfully identifies aging genes validated in a fly model.

Among the factors that predict fitness in wild baboons, dominance rank in males, but not in females, is the best predictor of epigenetic aging.

Latest advances in biological timing studies substantiate an emerging concept of autonomous clocks that are normally entrained by the cell cycle and/or the circadian clock to run in synchrony, but have evolved to run independently to regulate different cellular events.

Studying the fecal microbiota of wild baboons helps provide new insight into the factors that influence biological aging.

The light-modulated protein kinase CDK5 is important for phase shifts of the circadian clock, impacting phase delays through calcium influx and signaling pathways, crucial for adapting to jet lag.

Among European children, shorter telomere length and older DNA methylation age relative to chronological age were associated with poorer behaviors, while older age, as predicted by a novel immunometabolic clock relative to chronological age, was associated with greater cognitive maturity.

The first epigenetic clock for rats was developed and revealed to reflect phenotypic aging and captured the effects of longevity interventions.

Molecular clocks that are robust to external fluctuations are vulnerable to internal fluctuations and vice versa.

Single cell analysis reveals how period differences between cells and cell-to-cell coupling generates the spatial structure of the plant circadian clock.
