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.

Dance Classes May Peak in Benefit at Just 20 Minutes for Older Adults

In healthy adults over 60, dance programs led to medium-to-large improvements in physical function across 24 studies. The sweet spot for benefits appeared to be around age 70-75, and surprisingly, ses...

This review suggests short dance sessions may support physical function in older adults.

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.

Vitamin C May Slow Primate Aging by Blocking Iron-Driven Cell Damage

As primates age, iron builds up in tissues and fuels a chain reaction of fat damage in cells. Researchers call this process "ferro-aging" and found that a specific enzyme (ACSL4) drives it. When aged ...

This study suggests vitamin C may help counter age-related iron-driven cell damage in primates.

How Your Immune System Rewires Itself from Birth to Old Age

Researchers mapped immune cells at the single-cell level across the human lifespan, from mid-fetal development through late adulthood. T cells showed the biggest age-related changes. A specific subset...

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...

Fish-Eaters and Vegetarians Show Slower Biological Aging Than Regular Meat-Eaters

Among over 400,000 UK adults, people who ate fish but little meat aged the slowest biologically. Vegetarians came in a close second. Regular meat-eaters aged fastest by two different biological age me...

This study suggests reducing meat and including fish may be linked to slower biological aging.
