[UC] Ancient Body Clock Discovered That Helps To Keep All Living Things On Time.

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."
Sweet mercy!

And how convenient it's at extactly 24 hours .

Just looked it up and I'll probably be occupied with this all day.

Thanks for the knowledge sir

I've always considered time to be a thing of human creation. As I believe time can be manipulated and can be conceived differently between the observers.

For them to possible find cells in your body that dictates this 24 hour cycle boggles my mind. Now I know that we have some sort of internal clock as thats why your body can wake up a few minutes right before your alarm goes off for example. But is that an actual "internal clock" or is it from habit?

Also, how did they determine it was a 24hr cycle?

hmmm, the article states that circadian rhythms control patterns of migration, which doesn't quite make sense, since circadian refers to a day cycle, not year cycle

I doubt this is as universal as the article claims. There is much life that has evolved to it's current state well out of reach of the sun or any perceptible day/night cycle.

Still, it doesn't seem at all surprising that life on the surface would have adapted to the solar cycle.

Also, the news is in the specifics. A 24-hour cycle has been long known. The understanding of the mechanisms behind it is what is new.

Time exists without us. Always has.

Without an internal clock, how could habit apply to such cases? No frame of reference, whether it be an internal clock, the sun, or something artificial, would mean that you'd wake up randomly.

Observation. You look for patterns in metababolism, reproduction, sleep cycles, etc. Then you look at your clock.

Well thats true when considering light.

However there are other things such as tides, temperature, behavior of food sources, etc all offer themselves as a hook for such organisms to also adopt a similar clock cycle.

It could even be an effect of gravitation by the moon. Just theorizing.

I mean cells and life have been living on this planet for a long time now. The sun has been doing its thing for all that time with the earth spinning and rotating.

Of course this is going to happen you silly people!
