Did not know there was any jellyfish that lives this long. Thou they call them immortal I would say we have not discovered their life span. In any event an interesting article from interestingengineering.com written by Nergis Firtina:
"Are we one step closer to unlocking the secrets of human aging?
ou might be familiar with the movie 'The Curious Case Of Benjamin Button'.
Button was suffering from a rare ailment that made him age backward. Meanwhile, in another similar scenario, a species of jellyfish — called turritopsis dohrnii — seems to have reached immortality.
A team of Spanish researchers has been successful in deciphering the genome of a jellyfish famed for its capacity to resurrect itself after death.
The study was published in PNAS on Monday.
Even after sexual reproduction, the tiny marine creature, known as the immortal jellyfish, can turn back the biological clock and transform into a group of juvenile cells.
Re-specializing the 'immortal' jellyfish
The Independent reported that Maria Pascual-Torner and her colleagues at Spain’s University of Oviedo examined the genomes of the immortal jelly to a closely related species, Turritopsis rubra, the crimson jellyfish, which cannot reverse its aging process as easily.
Looking at the two medusas, researchers discovered that the immortal jellyfish had mutations that allowed it to limit cell division and prevent telomeres, the protective caps over the chromosomes, from breaking down. It also had two times the number of genes linked to DNA repair and protection.
In addition to silencing developmental genes to revert to their earlier forms, the immortal jellyfish also triggered additional genes that allowed the reverted cells to "re-specialize" as the colony split off into swimming individuals once again.
More specifically, medusae, or adult jellyfish, reverse their genetic clock to become larval once more when they perceive a threat from changing environmental conditions. They are merely a thin layer of cells and tissue that float through the water in search of a rock or seagrass blade to cling to.
Are humans closer to immortality?
The scientists expressed hope that their genome mapping might result in discoveries on human aging and initiatives to lengthen life expectancy, as reported in The Wall Street Journal.
"It’s a mistake to think we will have immortality like this jellyfish because we are not jellyfish,” she said. But it’s possible something in the immortal jellyfish’s evolutionary trick can be used to better understand the pathologies of aging," Pascual-Torner said.
The study contained an important message about extending an organism's health span, or healthy years, according to Dr. Jan Karlseder, a molecular biologist and director of the Glenn Center for Biology of Aging Research at the Salk Institute.
"The most interesting thing is that it’s not a single molecular pathway…It is a combination of many of them,” he said.
"If we want to look for an extension of healthspan, we cannot just focus on one pathway. That will not be sufficient. We need to look at many of them and how they synergize," he added.
Study abstract
Turritopsis dohrnii is the only metazoan able to rejuvenate repeatedly after its medusae reproduce, hinting at biological immortality and challenging our understanding of aging. We present and compare whole-genome assemblies of T. dohrnii and the nonimmortal Turritopsis rubra using automatic and manual annotations, together with the transcriptome of life cycle reversal (LCR) process of T. dohrnii. We have identified variants and expansions of genes associated with replication, DNA repair, telomere maintenance, redox environment, stem cell population, and intercellular communication. Moreover, we have found silencing of polycomb repressive complex 2 targets and activation of pluripotency targets during LCR, which points to these transcription factors as pluripotency inducers in T. dohrnii. Accordingly, we propose these factors as key elements in the ability of T. dohrnii to undergo rejuvenation."
Interesting article for sure and may one day show how to cure some rapid aging illnesses to prolonging lives and rapid healing if in an accident. There are some dark sides as well, but there are as noted above some good sides of this research.

I have lost a lot of faith with the Medical Community and the Governments over the last several years, but there are a few good things that can raise above the corruption and the pushing of drugs a new approach to heal people. The following is from www.gaia.com and written by Hunter Parsons that does not involve any drug or pushing an ineffective so called vaccine that the drug company is not held accountable in any way but they use sound! The use of sound can regrow bone tissue! Here is the story:
"The future of regenerative medicine could be found within sound healing by regrowing bone cells with sound waves.
The use of sound as a healing modality has an ancient tradition all over the world. The ancient Greeks used sound to cure mental disorders; Australian Aborigines reportedly use the didgeridoo to heal; and Tibetan or Himalayan singing bowls were, and still are, used for spiritual healing ceremonies.
Recently, a study showed an hour-long sound bowl meditation reduced anger, fatigue, anxiety, and ...
Not a fan of a Defense Agency studying Anti-Gravity and other Exotic Tech, but if the commercial world and make this technology cheap that will change our world yet again. The following is about three minute read and from www.gaia.com. The below was written by Hunter Parsons:
"Wormholes, invisibility cloaks, and anti-gravity — it’s not science fiction, it’s just some of the exotic things the U.S. government has been researching.
A massive document dump by the Defense Intelligence Agency shows some of the wild research projects the United States government was, at least, funding through the Advanced Aerospace Threat Identification Program known as AATIP.
And another lesser-known entity called the Advanced Aerospace Weapons System Application Program or AAWSAP
The Defense Intelligence Agency has recently released a large number of documents to different news outlets and individuals who have filed Freedom of Information Act requests.
Of particular interest are some 1,600 pages released to Vice News, which ...
As our technology gets better we are discovering more about the history of mankind and pushing the timeline back further and further. The following article is from www.gaia.com and written by Michael Chary that discusses this new find that changes the historical timeline:
"Over the past decade, there have been a number of archeological revelations pushing back the timeline of human evolution and our ancient ancestors’ various diasporas. Initially, these discoveries elicit some resistance as archeologists bemoan the daunting prospect of rewriting the history books, though once enough evidence is presented to established institutions, a new chronology becomes accepted.
But this really only pertains to the era of human development that predates civilization — the epochs of our past in which we were merely hunter-gatherers and nomads roaming the savannahs. Try challenging the consensus timeline of human civilization and it’s likely you’ll be met with derision and rigidity.
Conversely, someone of an alternative...
Not sure if you have heard of a show on YouTube called "The Why Files". If not you should check it out it is interesting and has some humor with it on different subjects. Last weeks was on a different theory how the Universe works and how main stream Science is attempting to shut it down like is always seems to do if it goes aguest some special interest. Today it is akin to what happened to those who questioned the Earth was the Center of the Universe that main stream so called Science all believed during the Renaissance period, They called any theory that the Earth was not the Center of the Universe misinformation. Does this sound familiar today? People laughed and mocked people like Leonardo da Vinci, Nicolaus Copernicus, Georg Purbach as crack-pots, conspiracy theorists, nut-jobs and they were suppressed and even imprisoned for their radical thoughts and observations. Again it sounds like today in so many ways. In any event this is a good one to ponder and see even if a bad idea ...
Seemingly chaotic systems like the weather and the financial markets are governed by the laws of chaos theory.
We all have heard about chaos theory, but if you have not or have forgotten what chaos theory is well here you go from interestingengineering.com:
"Chaos theory deals with dynamic systems, which are highly sensitive to initial conditions, making it almost impossible to track the resulting unpredictable behavior. Chaos theory seeks to find patterns in systems that appear random, such as weather, fluid turbulence, and the stock market.
Since the smallest of changes can lead to vastly different outcomes, the long-term behavior of chaotic systems is difficult to predict despite their inherently deterministic nature.
As Edward Lorenz, who first proposed what became commonly known as the Butterfly Effect, eloquently said, "Chaos: When the present determines the future, but the approximate present does not approximately determine the future.""
You may have heard the term about chaos theory as a butterfly flaps its wings in Brazil,...
I for one have lost trust in Medical Doctors due to COVID and reflection that they seem to push pills for everything and untested so called vaccines that is using a unproven technology because the Government and the Medical Boards of the State told them to. There are a very few exceptions. Thus they do not address the key problem just prescribe more and more pills to keep you alive an sick longer for them and Big Phama to profit from you. Will AI do any better? Well that depends on what was used for the training of AI. If it also pushes pills and vaccines without question then you have the same problems noted above. However, if the AI Training includes all possible forms of treatment and they zero in on the right issues for the true problem then there is possibilities they would be way better than most of the current Medical Doctors today.
The following is from an article from interestingengineering.com and written by Paul Ratner:
