Across metazoans, lifespan varies greatly, not only among species but also within the same species. Much effort has been devoted to discovering genetic and abiotic factors associated with longevity in humans, and many lifespan-extending perturbations in model organisms like C.…

let-7 microRNA absent in many Caenorhabditis nematodes
A recent paper by Nelson and Ambros [1] reports that let-7 heterochronic microRNA is absent in Caenorhabditis species of the japonica group. Research in C. elegans has shown that let-7 plays an essential role during larval to adult transition and mutations…
