LONDON, Sept 9: – Scientists have found a genetic mechanism in mice that hampers their body clock’s ability to adjust to changes in patterns of light and dark, and say their results could someday lead to the development of drugs to combat jet lag. Researchers from Britain’s Oxford University and from the Swiss drug firm Roche used mice to analyze patterns of genes in an area of the brain called the suprachiasmatic nuclei (SCN) – which in mammals pulls every cell in the body into the same biological rhythm.
