Fruit Flies Could Reveal Cure for Jet Lag
Filed under: add to del.icio.us
A geneticist the University of Pennsylvania noticed that the fruit flies in her lab slept normally when bathed in light for 24 hours a day but tossed and turned when shifted from one day/night cycle, or "time zone," to another. The flies lacked a protein that helps to regulate their body clocks and allows them to adapt to changes in the duration of light and darkness. If a similar protein operates in humans, it could be possible to banish jet lag altogether.
