Biology and full moon nights

Posted by isabelaz on 15 May 2009 at 17:26 GMT

It seems there is no end to nature complexity!
This description of interactions between blue light, cryptochrome - a photoreceptor involved in biological clocks, and magnetic field, beyond the amazing talk between so different physical entities, speaks for the crucial importance of time in biology. The fact that magnetosensitivity of cryptochrome depends on blue light is compatible with the hypothesis of special sensitivities in full moon nights [1]. Amazing!
