Circadian Rhythyms Originate in Red Blood Cells

Whoa, this is interesting: “One study, from the Institute of Metabolic Science at the University of Cambridge, 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.”

The implications of these finding will have huge impacts on developing therapies for jet-lag, shift-work and metabolic disorders such as diabetes, mental health problems and even cancer.  [via geekosystem]
