The mechanism that controls the internal 24-hour clock of all forms of life from human cells to algae has been identified by scientists. Not only does the research provide important insight into health-related problems linked to individuals with disrupted clocks - such as pilots and shift workers - it also indicates that the 24-hour circadian clock found in human cells is the same as that found in algae.
A study from the University of Cambridge's Institute of Metabolic Science, has for the first time identified 24-hour rhythms in red blood cells. This is significant because circadian rhythms have always been assumed to be linked to DNA and gene activity, but - unlike most of the other cells in the body - red blood cells do not have DNA.
