Researchers find how liver cells control biological clock
Updated : 2 years, 10 months ago IST
To control their activity according to the time of day, organisms rely on a biological clock known as the 'circadian' clock. A central clock, made up of a collection of brain cells known as suprachiasmatic nuclei (SCN), synchronises the circadian clocks found in all of the body's organs, kno
