25,000 tissue samples show organs age at different rates; blood tests flag 8 diseases

Eric Topol highlights an open-access Nature Medicine paper, 'Histological aging signatures for monitoring tissue-specific aging and disease':
- Organs and tissues age at very different rates, each with its own clock
- This tissue-specific aging can be detected via blood tests
- The blood-test clocks predicted 8 diseases indexed to accelerated organ aging
- Based on 25,000 tissue samples across 40 tissue types from nearly 1,000 individuals
The work builds aging signatures from histopathology images — a classic AI-for-Science application.
