Jet lagged?—A recent murine study in Science (doi:10.1126/science.1245474) may just have the answer. According to Japanese researchers at Kyoto University, mice that lack receptors for the neuropeptide arginine vasopressin could be resistant to jet lag. The mice were able to adjust to the clock being put back eight hours in a single day, compared with the six days needed by normal mice. These findings have implications for shift workers who would benefit from being able to realign their circadian rhythms. However, the authors warned that any treatment targeted at vasopressin receptors would need to be carefully tested to ensure that it has no adverse effect on other organs of the body, such as the kidney, where vasopressin receptors play an important part in water reabsorption.
