Journeys across several time zones make our internal body clocks go haywire. We feel exhausted and tense, and our sleep pattern is out of synch. As scientists at the Max Planck Institute for Biophysical Chemistry have now succeeded in demonstrating for mice, the clocks associated with individual organs in the body adapt to the new time at different speeds. As a result, the body's physiological processes are no longer coordinated. The adrenal gland plays a key role in this process. When the...
