Immortality

>>8597043
No because cells also deal with problems that aren't solved by maintaining proliferative capacity, which will eventually overcome the body unless you treat them

>>8597043
Yes. But we would also develop cancer that had to be removed constantly.

I've been seeing a rise in biological immortality threads on /sci/ and in the news. What's up with that?

Also there has been a rise in want to be edgy nihilist shit posters as well.

I think you could circumvent that problem, by not making your cell immortal. But increase the length of your telomeres and then repeat the treatment after a while. Then senescent cells should become able to divide again, but cancer cells that would proliferate a lot faster than normal cells, would not be able to proliferate indefinitely.

/pol/esmokers have been shitposting here for a while

>>8597094
so like a temporary treatment of telomerase?

Cells don't always enter senescence just because they run out of telomeres, IIRC. If the cells just accumulates enough stress it'll just shut down growth indefinitely anyway, after accumulating proteins that are made in response to cell arrest signals (cells will normally say fuck no to mitosis if it knows crazy shit is going down, ie you got shot with x-rays).

You can have non-tumorigenic immortalised cell lines i.e. immortalised cells that aren't cancerous.

There are other problems with immortalising cells, this isn't really a good one to start with.

apologies on behalf of /pol/.. we should never interfere with /sci/'s white-guilt + EM drive threads.

I'll get the Bogs on you for that

>>8597115
What does /sci/ have to do with white guilt?

>>8597085
SAD and college freshmen realizing uni doesn't suddenly make you whole.

>so like a temporary treatment of telomerase?
yes, I think directly cellular immortality, would be dangerous because of the likelihood of survival of "rouge cells" and I don't think a universal cure to cancer will be developed in this century.
If you went with stimulating regrowth of telomers with spaced intervals .Then you could reduce the likelihood of rouge cells turning into full blown cancer.

Is it possible to reinduce the ability of replication in senescence cells? - yes it is. If it takes more than just applying a telomerase treatment, then that would complicate things, but it would still be feasible.

Isn't that what SENS currently trying to do? Treatment where you go in get it, come back 20 years do it again, and repeat.

>>8597185
don't know what SENS is trying to do, as far as I understand then it is that guy, Aubrey de grey or something like that, I was under the assumption that he was more meme than man.

But if that is what they are trying to do, then they sound somewhat reasonable, since they must have reached the same conclusion that I have.

>>8597198
>more of a meme
Well he hasn't been proven wrong with his idea, and used his own most of the millions from his inheritance to help fund his group and work.

If he was a meme that would be taking it too far.

Life extension that leads to biological immortality for 1st worlders: 2030s.

Calling it now.

seems a little short.. let's say there is a periode of a ~7 year drug trial, before such a drug can enter the market. So the blueprint of a potential drug should already be in the progress now, if your prophecy were to be true.

But again, as I understand it they have already have made some progress with mice. But you know the saying "we have cured cancer thousands of times - in mice".

>>8597263
A lot more progress would be made if we tested humans instead of mice.

>>8597263
>Mice
If I remember correctly they managed to reverse age within a few month old mice, but the mice got cancer.

Which isn't bad as it showed progress. I'm sure there is an article on the thing floating about.
