The three living beings who have learned the secret of eternal life

The three living beings who have learned the secret of eternal life

From ancient giant tales to science fiction literature, there are many stories of our quest for eternal youth. But there are also creatures who have the secret to stopping and even reversing the natural aging process. have known

And these are actually found.

These are the animals that are biologically immortal or so we think. This means that unless a predator, disease or drastic change in the environment kills them, they survive. Can Prevent Aging? Three of these surprising organisms are:

Planaria

It has been known since the late 19th century that these ticks can regrow even if they are cut off, but in 2012 the University of Nottingham published a study on their possible immortality. Planaria are a type of flatworms, or flatworms, that are found all over the world and can produce unlimited stem cells. Planaria are of two types, one that reproduces sexually and the other that a. Sexually i.e. asexually, they divide themselves into two halves to form new pleniaria.

Planaria

Scientists at the University of Nottingham examined both species and found that those who reproduce asexually give their DNA a ‘new lease of life’.

At some point in our lives, like most animals, our DNA reaches its cell division limit and our bodies begin to decay. Planaria, on the other hand, contain large amounts of enzymes that These enzymes protect their cells from aging and are regenerated when they go through the reproductive process, leading scientists to believe they are immortal.

 

Hydra

This organism, which seems to be a creature from another planet, is found in fresh water. Its body is like a tube. Through filaments near their mouths, they catch their prey, which may include small earthworms and other aquatic organisms. were the first organisms involved. Shortly thereafter, Swiss scientist Abraham Tremblay’s hydra and its ‘superpowers’ of regenerating body parts ushered in a new era in biology. can recreate parts of In order to understand their potential immortality, it is important to understand their stem cells, which self-reproduce in an infinite manner. In fact, the entire body of a hydra appears to be made of self-renewing stem cells. Be made

Hydra

Scientists who studied a group of hydra over several years showed no signs of aging. In 2018, researchers at the University of California, Davis, hypothesized that hydra are likely immortal because they carry transposon genes. or can control genes called ‘jumping genes’.

These are genes that can ‘jump’ from one part of the genome to another, causing genetic changes. When we’re young, our bodies can control these genes, but as we age, we lose control of these genes. Well, we have a hard time controlling them. Hydra, on the other hand, can probably keep these genes under control forever.

 

Tritopsis dohernii: The Immortal Jellyfish

Tritopsis dohernii: The Immortal Jellyfish

Immortal jellyfish whose scientific name is Tritopsis dohrnii are found in marine waters. They were first discovered in the Mediterranean Sea in the 1880s. They are very small and like to eat seaweed, fish eggs and small snails. The amazing thing about this jellyfish is that it turns its life upside down. When it is stressed, it carries itself into the prime of its life.

It is like a butterfly turning into a moth again. This happens through a step called transdifferentiation.   Transdifferentiation occurs when a fully mature cell transforms itself into another type of mature cell. This entire stage is still a mystery to scientists. And not only that. When this jellyfish reverts to its earlier life form, it gives birth to other organisms with the same genetic code, in a way, itself. Along with giving new life, it also reproduces itself.
