In the field of aging research a great many as yet unexplained correlations exist, any one of which may point the way to important new knowledge. Take this for example: \"Biological rhythms that <a href=\"http:\/\/en.wikipedia.org\/wiki\/Circadian_rhythm\">oscillate with periods close to 24 h (circadian cycles)<\/a> are pervasive features of mammalian physiology, facilitating entrainment to the 24 h cycle generated by the rotation of the Earth. In the absence of environmental time cues, circadian rhythms default to their endogenous period called tau, or the <a href=\"http:\/\/en.wikipedia.org\/wiki\/Free-running_sleep\">free-running period<\/a>. This sustained circadian rhythmicity in constant conditions has been reported across the animal kingdom, a ubiquity that could imply that innate rhythmicity confers an adaptive advantage. In this study, we found that the deviation of tau from 24 h was inversely related to the lifespan in laboratory mouse strains, and in other rodent and primate species. These findings support the hypothesis that misalignment of endogenous rhythms and 24 h environmental cycles may be associated with a physiological cost that has an effect on longevity.\"<\/p>\n<p>View the Article Under Discussion: <a href=\"http:\/\/pmid.us\/20392719\">http:\/\/pmid.us\/20392719<\/a><br \/>\n<br \/>Read More Longevity Meme Commentary: <a href=\"http:\/\/www.longevitymeme.org\/news\" \/>http:\/\/www.longevitymeme.org\/news\/<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Scientists proceed in their work by discovering a correlation and then picking apart the underlying mechanisms to find out why the correlation exists.
