(PhysOrg.com) -- Jet lag, as every long-distance airline passenger knows, disrupts the body's normal circadian rhythms, or body clocks, and causes some very unpleasant effects such as disturbed sleep and fatigue. Now scientists ...
Using automated screening techniques developed by pharmaceutical companies to find new drugs, researchers from UC San Diego and three other research institutions have discovered a molecule with the most potent effects ever ...
