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 before it starts.

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

A new study could help identify promising treatments to extend the human lifespan, researchers say
