Recent social historical studies on the development of life expectancy over the last 300-400 years have shown that the increasing certainty that the great majority of us will be able to live relativel...
Mice of the autoimmune, lymphoproliferative strain MRL/lpr and the congenic, nonlymphoproliferative strain MRL/n were fed one of six diets from weaning on-ward. These mice were sacrificed at 3 or 5 mo...
The dynamics of life span (LS) and fecundity in Drosophila melanogaster, strain D-32, were analyzed in a series of successive generations. Highly reliable variations in both fitness components were fo...
Loss of the protein kinase Sch9p increases both the chronological life span (CLS) and the replicative life span (RLS) of Saccharomyces cerevisiae by mimicking calorie restriction, but the physiologica...
The observation that fusion of infinite life span cells with finite life span cells produces hybrid cells with finite life spans led to the conclusion that an infinite life span in culture is a recess...
The dynamics of life span (LS) have been studied in successive generations of postirradiation and control groups of Drosophila melanogaster, strain D-32, after a single exposure to Co60 gamma-quantum ...
