Cellular-ageing clocks based on gene activity could be more sensitive than previous measures.

Cellular-ageing clocks based on gene activity could be more sensitive than previous measures.

The new tool can predict ageing in rodents and monkeys — and time to death in people. Plus, zebrafish sleep in stages, similarly to humans, and the race to intercept lung cancer…

Swiss-assisted researchers develop "gene clocks" to measure biological age and remaining lifespan.
