A research team in Northeastern University, leading by Javier Apfeld, has been studying in the connection between brain signaling and the aging speed of organisms. In the advantages of hermaphroditic individuals and short lifespan, C. elegans, is one of the best organisms for the study of life science.
By manipulating the living environment or neurons of C. elegans, their lifespans can be altered. Dietary restriction and lower temperature are two mainly manipulations they discovered to prolong lives of C. elegans. Researchers are eager to discover less stressful ways that affect lifespan of organisms.
