This article focuses on the potential for older females to continue having children because of changes in their biological clock that allow somatic cell ages to synch up. They’re looking at the gene (TGF-β) in C. elegans worms and this mutagen gene allows for fertile eggs to be made up until the day the worm died. Since they’re finding a separate set of genes that control reproduction instead of bodily aging, it’s becoming more likely that they can mutate the reproduction genes to keep eggs fertile longer.
