Frailty Markers Predict 20-Year Death Risk in Older Chinese Adults

In about 4,000 older Hong Kong adults tracked for nearly two decades, frailty measures strongly predicted who would die and from what cause. Being frail was linked to a 66% higher risk of death compar...

This study suggests frailty assessments could help identify older adults at higher mortality risk.

Fish That Age Fast Reveal Predictable 'Life Stages' in Aging

Scientists tracked African killifish behavior continuously from adolescence to death. Long-lived fish behaved differently from short-lived ones surprisingly early in life. Machine learning could actua...

This study suggests aging may follow structured, predictable stages rather than a gradual slide.

New Aging Clocks Built From Histone Marks Work Across Species

Researchers built 36 new biological aging clocks using histone modifications (chemical tags on the proteins that package DNA) instead of the usual DNA methylation approach. These clocks worked well ac...

Red Blood Cell Proteins Can Track Biological Aging and Predict Health a Decade Later

Researchers built a protein-based aging clock from the red blood cells of over 13,000 blood donors. People with conditions like G6PD deficiency and sickle cell trait showed accelerated molecular aging...

This study suggests red blood cell proteins could serve as accessible markers of biological aging.
