Can jellyfish live forever?
« on: 09/09/2009 20:11:22 »
A few weeks ago a friend of mine asked me the simple question, "Does everything die?" I instantly was like "Well obviously" and then he had told me about a type of jellyfish that was discovered that could live until it reaches maturity then its aging process somehow reverses, What i would like to know is, if this is in fact an immortal creature, could we somehow use this creatures DNA/Etc. to our own benefit? Im not purely suggesting that we could achieve being immortal, but Im thinking along the lines of somehow using it to maybe slow the rate at which we age?

Quote from: National Geographic
Miglietta (Maria Pia Miglietta, a researcher at Pennsylvania State University) dismissed news reports from this week that implied the jellyfish could hold a key to anti-aging drugs for humans.

"Nobody is looking into that," she said, "and I don't think you're going to find any secrets in these creatures."

Bold statement.
I say don't change the title back until you present the proof :)

Google is not proof you silly :D I find The Sun, the Daily Mail as sources for this info.  ::)

PubMed, ISIKnowledge, science-direct, is a lot closer to proof..

And I'm guessing that study into these jellyfish does not benefit the slowing of humans.

Assuming the link two posts above is correct scientific data, then I conclude that the jellyfish as an organism is not immortal.
Only it's cells are immortal.

And the source explains what happens to the cells: in simple terms, the cells of an adult jellyfish specimen transdifferentiate into cells of juvenile polyps. The article mentions that theoretically, this cycle can go on infinite, but have they really looked into it?
It might as well only work 10 times, if the jellyfish cells would have an analogue to what we humans have as telomers.

Further investigation is required, and I remain sceptical

I actually read somewhere, not sure at the moment, but it stated that scientists did do a study and all of them lived and never died. Plus wouldent it be possable to find the remains of any deceased ones? And if so why havent there been any found?

well, they'd be eaten pretty quick, and we don't walk in the sea every day :)

We "Humans" do, someone everyday touches and/or will be taking steps at the bottom of the sea floor. Next time use harder wording lol. :P

This jellyfish is only 4.5 mm in diameter
