Ambika at the National Zoo in Washington, DC is thoght to be 71 years old, likely making her the … But its unique ability was not discovered until the 1990s. But when starvation, physical damage, or other crises arise, "instead of sure death, [Turritopsis] transforms all of its existing cells into a younger state," said study author Maria Pia Miglietta, a researcher at Pennsylvania State University. Miglietta speculates that the creatures have very effective cellular repair mechanisms that allow them to age without incurring the usual ravages of time. The discovery underscores "our remarkable underestimation of the extent to which the ocean has been reorganized," said Carlton, who also was not involved in the research. About as wide as a human pinky nail when fully grown, the immortal jellyfish (scientific name: Turritopsis dohrnii) was discovered in the Mediterranean … For reasons still mysterious, the immortal jellyfish takes on slightly different forms as it spreads. According to a study utilizing eye lens radiocarbon testing, the minimum life span … THIS year, Tommy the tortoise turned 121, having been born in 1898. Like all jellyfish, Turritopsis dohrnii begins life as a larva, called a planula, which develops from a fertilized egg.A planula swims at first, then settles on the sea floor and grows into a cylindrical colony of polyps.

But while they won't yield the next Botox, the jellyfish just might help fight one of human health's greatest threats—cancer—according to biologist Stefano Piraino of the University of Salento in Italy. 586-591). Like cancer cells, "some cells of this jellyfish that were supposed to [die] … are able to switch off some genes and to switch on some other genes, reactivating genetic programs that were used in earlier stages of the life cycle," Piraino said. The immortal jellyfish (as it is better known popularly) propagate and then, faced with the normal career path of … All rights reserved. In it, there is an account of the great sage Utnapishtim, who is warned of an imminent flood to be unleashed by wrathful gods.

What is the longest living creature […] These small, transparent animals hang out in oceans around the world and can turn back time by reverting to an earlier stage of their life cycle. No turritopsis dohrnii has been observed in a laboratory for an extended period of time, and there is no other way to establish the age of an individual. It hails … No turritopsis dohrnii has been observed in a laboratory for an extended period of time, and there is no other way to establish the age of an individual. Turritopsis nutricula, or sometimes - Turritopsis dohrnii, is able to transform its cells from mature state back to immaturity, in other words - back to youth.

Maria Pia Miglietta, an assistant professor in the Department of Marine Biology at Texas A&M’s Galveston campus, received an Early Concept Grants for Exploratory Research (EAGER) National Science Foundation (NSF) grant to study cell regeneration and gene sequencing within a very special jellyfish, the Turritopsis dohrnii, or T. dohrnii. Imagine this… You’re old, with a hunched back and greying hair. Jellyfish can be found in seas all over the world and they are one of the oldest multi-organ animals, inhabiting our planet for 500 million years.
