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.

One tiny chemical difference between RNA and DNA may help explain how life began
Scientists may have found a clue to one of the biggest mysteries surrounding the origin of life: how fragile RNA molecules could gather and survive before cells existed. New research shows that RNA is unusually good at assembling into tiny liquid-like droplets that concentrate mo
