[National Geographic] "Immortal" Jellyfish Swarm World's Oceans

post #1 of 21
Thread Starter 
Quote:
A potentially "immortal" jellyfish species that can age backward—the Benjamin Button of the deep—is silently invading the world's oceans, swarm by swarm, a recent study says.

Interesting read I thought I would share with ya'll. thumb.gif

WOW! I'm literally left speechless! Not only can they reverse their age, multiple time's but they can also clone themselves in the process! I'm still not sure I fully believe this! I'm off to google about these guys!

A little old, yeah. But it's my first time hearing about it and I think it's pretty cool.

I am confused though; the article says the jellyfish will revert to a cyst, and later develop into a polyp colony. This makes sense if it's physically damaged, but for a jellyfish that's starving to death, wouldn't this process require a lot of energy?

Get this stuff working in me. Spare me the technical thing. I volunteer for beta testing.

There are many creatures suspected to have indefinite life spans, but how these jellyfish go about it is pretty interesting.

Potentially a lot.

Being able to undifferentiate one's cells and allow them to be reconfigured would be huge. Learning exactly how this is triggered, and replicating it in higher animals, could have a profound impact on medicine.

It would be like a starving man transforming himself into a child or two. Even though the man is starving, he's still made of way more stuff than a healthy child is. That's a very rough analogy, but it should get the point across.

Not exactly, but this process would essentially kill him, if the full equivalent could happen to a human.

Everything anyone is, as a person, is part of the physical structure of their brain. Your body completely undifferentiated, then reformed itself from scratch, you'd be a blank slate.

The idea would be to selectively undifferentiate cells, so that missing parts and other serious damage could be regenerated. I don't think most people would want to clone themselves at the cost of their own lives.
