title: Cellular senescence: lessons from yeast for human aging?
abstract: Recent results point to an important role for the nucleolus in the senescence of yeast cells. A further report suggests that the formation and preferential accumulation in mother cells of extrachromosomal rDNA circles is a cause of aging in yeast; this may be an ancient and conserved mechanism of senescence.
