By Heidi Ledford of Nature magazine A widely touted–but controversial–molecular fountain of youth has come under fire yet again, with the publication of new data challenging the link between proteins called sirtuins and longer lifespan. In a paper published today in Nature , researchers report that overexpressing a sirtuin gene in two model organisms–the nematode Caenorhabditis elegans and the fruitfly Drosophila melanogaster –does not boost longevity as had been previously reported.
