Hydrogen sulfide provides clues to a longer life

Hydrogen sulfide, or H2S, the chemical that gives rotten eggs their sulfurous stench - and the same compound that researchers at Fred Hutchinson Cancer Research Center successfully have used to put mice into a state of reversible metabolic hibernation - has now been shown to significantly increase life span and heat tolerance in the nematode worm, or C. elegans.
