Scientists found an oldest immortal jellyfish i.e. The Benjamin Button Jellyfish. Turritopsis dohrnii is the scientific name of this jellyfish.
When T. dohrnii reach adulthood, they regenerate their cells back into their childhood which backwards their age.
This allows T. dohrnii to bypass death and make them potentially biologically immortal.
Scientists found that the gene in mitochondrial RNA (mRNA) was responsible for its immortality power.
If this technology is developed and experimented on humans then we can find the cure for issue of Human Aging and Diseases.
