NIH researchers researchers and collaborators have gained some key insights into the biological inner-workings of regrowing a body, the evolution of aging and a unique method to dispose of aging cells, by studying the genomes of a hermit crab (Hydractinia symbiolongicarpus).
… detected a molecular signature associated with the biological process of aging, also known as senescence. … Reports , Hydractinia demonstrates that the fundamental biological processes of healing and aging are intertwined, … of unusual organisms reveal both how universal many biological processes are and how much we have yet to …
