The observation that long-lived and relatively healthy animals can be obtained by simple genetic manipulation prompts the search for chemical compounds that have similar effects. Since aging is the most important risk factor for many socially and economically important diseases, the discovery of a wide range of chemical modulators of aging in model organisms could prompt new strategies for attacking...
Mild hormetic heat treatments early in life can significantly increase the lifespan of the nematode C. elegans. We have examined the effects of heat treatments at different ages and show that treatments early in life cause the largest increases in lifespan. We also find that repeated mild heat treatments throughout life have a larger effect on lifespan compared to a single mild heat treatment early...
