2Frailty 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 compared to being fit. Adding blood-based markers like inflammation and kidney function to frailty scores slightly improved predictions. One surprise: none of the biological aging markers predicted cancer deaths specifically.
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 across six tissue types and could detect accelerated aging in leukemia samples and age reversal after treatments. One surprising finding: many aging-related changes peak at midlife rather than climbing steadily. The approach even worked in fruit flies, which lack DNA methylation entirely.
