    The Curious Case of the Immortal Jellyfish | Discoblog | Discover Magazine

    Jellyfish that can age backwards are invading the world's oceans | Worldhealth.net

    This tiny, 5mm-wide hydrozoan is the only known animal capable of rolling back the clock, willfully reverting to its immature stage, thus living indefinitely.

    More fascinating still, this particularly species, native to the Carribean, has slowly been conquering the world, and now can be found in most of the world's oceans.

    What a wonderful world!


    The good news? We're getting much closer to clinical regeneration:

    The downside? The genes that prevent us from regenerating limbs like other species, also prevent us from rapidly developing cancers. Catch-22?

    i saw a thing on the discovery channel that said, the next life expectancy on humans is going to be a THOUSAND YEARS.....say what? yes, a thousand years....it showed how close we were to actually making that a reality....

    for goodness sakes.... the world could not accommodate or support that, and they know it...so why pursue this?

    In nature, the shorter-lived an organism, the faster it reproduces.

    You could argue that, with a lifespan of 1000 years, we'd have much less motivation to reproduce. A combination of reduced reproduction rates and renewable energy would make this practical, assuming we can biologically make it happen.

    Also, living 1000 years, we would have plenty of bodies to put into space. There is no commodity with more potential uses than the human brain.

    There is a reason why we have such things as cancer, AIDS, etc. IMO

    While I'm not optimistic enough to suggest that I will live to be 1000, given the current rate of advance, I think it is reasonable to plan for a retirement starting at 100.

    Seeing how Technology and Medicine are advancing pretty fast i wouldn't doubt seeing the life expectancy to be over 100-110 when i get to my 50's.

    I can testify that this is not always true.

    I am surprised I made it to 45.

    I tell you right now, the second I am condemned to bingo and applesauce Tuesday, I am going to take it shotgun-standing just like Hemmingway.

    I...I don't what to say. I have relatives in nursing homes, and thought they seem happy when I visit, I cannot help but wonder if they resent us for keeping them around in this condition.

    Well, cancer is simply runaway growth,yes?

    So it follows that a mutation that limited growth could aid in preventing many cancers while also severely limiting the ability to heal and that a mutation which enables the regeneration of whole limbs might also lead to a higher risk of such uncontrolled growth, yes?

    Of course, unless you plan to somehow deactivate it in living persons (is there any known way to achieve such a thing? Perhaps epigenetics is the key? My knowledge here is very limited and that of a mere curious layman), you face to moral/ethical dilemma of whether to test it on new humans.
