Dr. Linda Buck of the research center says it remains unclear why, depriving the body of all but the minimum amount of calories needed to survive seems to enhance longevity but the Seattle team believe they may have found an easier way to achieve the same effect.
Nematode worms are ideal subjects for studies into lifespan, they are similar in many ways to humans as they have a central nervous system and sexual reproduction; they also only live for only a matter of weeks.
