Computer model of the molecular structure and function of the circadian clock Kai protein in cyanobacteria LAGUNA PHOTO LIBRARY
In a test tube, a circadian clock was recreated in its entirety. This is the first time that a cellular pacemaker has ever been created outside of a living organism.
Carrie Partch, University of California Santa Cruz and her colleagues invented the clock from a cyanobacteria. It is composed of six proteins and can function for many days without human intervention. The record so far is probably two weeks.
