The freshwater polyp Hydra oligactis is essentially immortal and reproduces asexually by cloning itself. Except when it gets too cold: then the animal switches to sexual reproduction, begins to age, and eventually dies. A research team at the University of Innsbruck has now investigated the metabolic changes that accompany this process. One of the findings: the aging process is accompanied by a sharp decline in taurine.
