Why is the polyp Hydra immortal ? Researchers from Kiel University decided to study it — and unexpectedly discovered a link toaging in humans […].
The tiny fresh water polyp Hydra does not show any signs of aging and is potentially immortal. There is a rather simple biological explanation for this : these animals exclusively reproduce by budding rather than by mating.
A prerequisite for such vegetative-only reproduction is that each polypcontains stem cells capable of continuous proliferation. Due to its immortality, Hydra has been the subject of many studies regarding aging processes for several years…
