By monitoring when and how often the mice chose to run on an exercise wheel the team spotted a change in some of the animals’ normal rhythms.
Instead of following the typical 24 hour pattern, some of the mice had body clocks that stretched to up to a 27 hour day.
Closer study of the DNA from the mice then revealed that those on a 27-hour-cycle had the after hours version of the Fbxl3 gene, one of a large family that controls the breakdown of specific proteins within body cells.
IT ALL MAKES SENSE!!! I love the number 27 because I am on a 27 hour NIGHT OWL GENETIC CODE! Yay for Science. Now perhaps, if I stopped “drinking coffee at midnight, when the moment is not right…”
