How understanding plant body clocks could help transform how food is grown
Have you ever had a bad case of jet lag? That horrible feeling when you get off a long haul flight and your body is telling you it's time to go to sleep, but the outside world is telling you it's time for breakfast? That's ...

A simplified method to assess the synchronization properties of the body clock
Numerous organisms are equipped with circadian clocks (internal body clocks) that help them adapt to daily environmental changes in light and temperature. For synchronizing the clock phase (timing) with these environmental ...

CERN facility takes a solid tick forward towards a nuclear clock
Atomic clocks are the world's most precise timekeepers. Based on periodic transitions between two electronic states of an atom, they can track the passage of time with a precision as high as one part in a quintillion, meaning ...

Clock
A clock is an instrument used to indicate, keep, and co-ordinate time. The word clock is derived ultimately (via Dutch, Northern French, and Medieval Latin) from the Celtic words clagan and clocca meaning "bell". A silent instrument missing such a mechanism has traditionally been known as a timepiece. In general usage today a "clock" refers to any device for measuring and displaying the time. Watches and other timepieces that can be carried on one's person are often distinguished from clocks.
The clock is one of the oldest human inventions, meeting the need to consistently measure intervals of time shorter than the natural units: the day; the lunar month; and the year. Devices operating on several different physical processes have been used over the millennia, culminating in the clocks of today.
