The Jellyfish That Rewinds Its Life

Nature hides strange wonders, but few are as jaw dropping as a jellyfish that refuses to grow old.

Turritopsis dohrnii begins life like any ordinary jellyfish, drifting and pulsing through the sea.

When it faces stress or the natural decline of age, it performs a biological magic trick.

Instead of dying, it reverts its cells and transforms back into its youthful polyp stage. It literally starts over.

Scientists call this shape shifting โ€œcellular transdifferentiation,โ€ a process that lets the animal switch cell types and rebuild itself from the ground up.

๐Ÿชผ Why Die?

This type of evolution feels magical, and borderline impossible, yet nature yet again surprises us.

With our world obsessed with newness and reinvention, this tiny jellyfish shows us how rebirth can really occur.

Even simple, tiny life can be circular, creative, and surprisingly resilient.

    Jellyfish, aren’t they one of the creatures without a brain? Politicians should be rejoicing at what they may be able to do as well.

    One day in the near future with advanced AI, a scientist will enable himself to imitate the ‘cellular transdifferntiation’ of the jellyfish, hop into a time machine, go back to the garden of Eden, stop Eve from eating the forbidden fruit and all mankind will be back and live for ever.
    Fantastical fiction.
