Forums / Biological Immortality

pixel
I was browsing my contingent of online webcomics when I found this.

Apparently, the cells taken from this woman's body are alive and immortal, continuing to reproduce and live even though she is long dead.

Scientists finally decided that this amoeba-like organism that formed is a brand new species, evolved out of the cells taken from this woman.

These cells are considered to be biologically immortal...they will continue to grow and reproduce forever.

Really interesting read, I think.

jesus that is a bit scary, fascinating but scary

That description is a bit ass-backwards. The circulatory and digestive systems themselves are comprised of cells, so it's rather simplistic to say that "body cells" can't survive without them; normal somatic cells can persist in culture just fine but "age" as their DNA degrades with repeated divisions (edit: also the cell environment in culture is significantly different than in culture... I don't want to go into too much detail here since I'm not familiar with integrins, cadherins, etc., etc.). Obviously the "mortality of cells" does not reflect the mortality of the greater organism as much as dictate it. A seemingly obscure paper by Van Valen (who doesn't even list it on his selected publications list; I'm guessing the "HeLa = species" paper was meant to be "cute", but it does provoke interesting thought about how to define speciation) is cited to support the idea that HeLa cells are a distinct biological species (apparently on the basis of how fecund they are). It is meaningless to state that the HeLa cell is "an animal with a mostly human genotype, but which does not develop into a human-like phenotype." How can a single cell possibly express any human-like phenotype?

because you touch yourself at night. dude. Van Halen was a ROCK BAND. you know, 'right now', 'Runnin' with the devil' 'Dance the Night Away'? it also comes from an unknown scientific source. i have never seen or heard of this from a reputable source. i think you found yourself a dud chaos.

I passed year 10 biology... (note that here in Australia the high school system ends in year 12, so year 10 biology was hardly good)

I like...evolution...

i enjoy natural selection! especially when I am the one doing the selecting!

Oddly enough, his name is Frank BEARD! So each of them has a beard! :P :lol:

yeah, but not all of them could spin thier instruments from thier belt buckles!

You all deserve death.

If you didnt understand the shit you should have just left it be; instead you infected with your already rampant idiocy.


Fuck. :angry:
pixel
but all the good points had been said after the first few posts, there was nothing but idiocy left. Theres only so far pretending to be intelligent can get you on a forum, eventually it all boils down to discussions about beards

As i stated earlier, you deserve a slow and exceedingly painful demise.

This forum wasnt great when i first joined, but it was okay. Now it just sucks ass; i see why Zero morpheous stays hooked up on that damn FF online all day and never comes here now. This forum is a git barn, a slowly dying one at that. And when it is alive you lot spam it with crappy jokes and bullshit that makes cow manure smell like roses.


You people make Rpgamer look so cool right now...

So no amazingly awesome response to Paul's argument then?

First off it wasnt an "argument" because nobody was debating. I said "discuss" not "debate". I cant go into detail for a plausable response to what he said because like Paul; when they start talking about integrins caderins and the lot i get lost.


But from what i read, It already IS a complete lifeform, these chordate/human cells evolved into some sort of amoeba, with a human genotype but a nonhuman phenotype. It does not suggest that a role-reversal can occur....that an amoeba may evolve into a chordate....since such an event would take more than one mutation.


So i dont think they express any human phenotypes i assume they express the human genotypes.

My crap wasn't meant to be any sort of argument. I just don't like to see busters (like the guy who wrote that to begin with) blab on as though mutant human cells are really fully "autonomous" entities and "scientists" means more than two authors of an obscure paper which I can't find at the moment. What else can a single human cell in culture be but "amoeba-like"? It's a trivial description like saying it has a human genotype but not phenotype.

As for FFO I couldn't care less that people jack off to shit like this.

right so roughly what has happened is that some cells taken from as womans body are immortal, for some reason. and so there now a new species. a amoeba-species, instead of a human one. is that about it? its hard to understand when you're a rampant idiot.

Meh, argument being a discussion turned into disagreement. All good.

When a person dies, the brain ceases to function, in turn stopping all other functions, including the supply of oxygen to all cells. I would think because of that, it's why we decompose, create gas and bloat and just smell all over ewey. They never stated what condition those cells were being contained in. Needless to say, they're being incubated in a place where there's oxygen and a constant food supply. Since there's no brain to eventually die off and kill those supply's, they will continue to live and multiply forever. Think - that's the only reason cancer cells ever stop growing, is because the host ceases to be (cancer is the uncontrolled growth rate of somatic [non-sex] cells)
