Molecular clocks that can provide accurate estimates of both molecular age and lifespan across multiple mammalian species and tissue types are presented in an article published in Nature this week. An ...

Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a perfectly repeatable way.

A research team at Charité–Universitätsmedizin Berlin has developed a test that can determine a person's chronotype based on their hair roots. It is intended to lay the foundation for circadian ...
