Biological ages have the potential to provide aging-related information beyond chronological age and can be predictive of mortality independently of both chronological age and different types of biological ages.

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.

A comparison of nine different approaches over a period of 20 years reveals the most promising indicators for biological age.

Brain-Age delta is a non-invasive marker of biological brain aging that is sensitive to the presence of risk factors and altered biomarkers of Alzheimer's disease in non-demented individuals.

A robust mouse multi-tissue age predictor is presented that can be used to assess the DNA methylation age of mouse tissues and test the effects of longevity interventions.

Unhealthy lifestyle habits in adolescence associate with accelerated biological aging in young adulthood, but shared genetic factors underlying both lifestyle and biological aging may largely explain the observed associations.

Site-specific DNA methylation analysis at three CG dinucleotides by pyrosequencing provides a reliable measure for epigenetic aging of mice.

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

Partial chemical reprogramming is able to reduce the biological age of cells by diverting them to a different metabolic state marked by a strong upregulation of mitochondrial oxidative phosphorylation.

A new cellular transport mechanism splits the substrate and separately translocates its fragments to achieve selectivity.
