Clocks coming out of a large clock as a 3D illustration. We age along two clocks: a chronological clock and a biological clock. The former is just a measure of how many birthdays you have celebrated — ...

Modern timekeeping relies on the accuracy of atomic clocks, which revolutionized timekeeping by using the quantum behavior of atoms to measure time. Discover how these incredibly precise clocks work, ...

A new study shows that the timing of the different clocks in our body depends on multiple stimuli. This was investigated in the liver- and muscle clock of rats, where only a combination of eating and ...

(The Conversation) — It is that time again. Time to wonder: Why do we turn the clocks forward and backward twice a year? Academics, scientists, politicians, economists, employers, parents – and just ...
