The daily rhythms of the body - once thought to be strictly governed by a master clock lodged in the brain - appear to be driven to a remarkable degree by tiny timepieces pocketed in organs all over the body. Whats more, these peripheral timepieces appear to be strikingly idiosyncratic in appearance - more like Swatch watches than the classic Timex. Clocks located in the liver and heart appear to use very different sets of genes to perform essentially the same functions, researchers at the Medical School (HMS) and the School of Public Health (SPH) report in the April 21 Nature online.
