Researchers already knew that the sleep patterns of mice would change to match the opportunity to feed, but they did not know the mechanism that enabled the change. What I thought was most interesting was how the researchers looked for the part of the brain at work. They bred mice without a certain master gene, and then target various parts of the brain with the gene, delivered in the shell of a virus. The results may among other things, provide a new method for preparing to deal with jet lag." Link to Original Source
