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 and dates back millions of years to early life on Earth.
"The implications of this for health are manifold. We already know that disrupted clocks - for example, caused by shift-work and jet-lag - are associated with metabolic disorders such as diabetes, mental health problems and even cancer. By furthering our knowledge of how the 24-hour clock in cells works, we hope that the links to these disorders - and others - will be made clearer. This will, in the longer term, lead to new therapies that we couldn't even have thought about a couple of years ago."
And how convenient it's at extactly 24 hours .
