We wanted to know: If you could flip the telomerase switch on and restore telomeres in animals with entrenched age-related disease, what would happen? Would it slow down aging, stabilize it, or even reverse it?
It was akin to a Ponce de León [the Spanish explorer looking for the Fountain of Youth] effect. When we flipped the telomerase switch on and looked a month later, the brains had largely returned to normal.One of the most amazing changes was in the animals' testes, which were essentially barren as aging caused the death and elimination of sperm cells. When we restored telomerase, the testes produced new sperm cells, and the animals' fecundity was improved - their mates gave birth to larger litters.
Why the "uh-oh" in the headline? I don't know. Just seems so big, possibly, it deserves an uh-oh.

all the cool medical breakthroughs seems to happen only in mice. Pretty soon they will overtake us and it will be all our fault. They'll have full heads of hair, long lasting erections, hardy bones, and cancer resistant genetic makeup.
We'll be powerless to stop our Frankenmice creations.

"I heard that while this apparently works, it also gave the mice cancer. Still no free lunch."
Cancer can be cured with treatments that damage cells.
Damaged cells can be fixed with treatments that cause cancer.
This cycle will fund healthcare long into the future.

By all means, we need to ratchet this up to tests on human subjects. Human subjects who vote Democrat. If amnesty and the DREAM Act are paths to a permanent Democrat majority, teleomerase therapy could result in a permanent Conservative majority.
The science is settled.

This is ironic, because cancer cells activate telomerase to become "immortal" (i.e. the mechanisms that normally lead to cell cycle arrest are blocked).
Also, the longer cells "live" and divide, the more chance there will be a DNCe replication error that leads to cell malignancy development.

yuck!

23 Speaking of which, who in the pharmaceutical industry decided that the cut off point for a too long lasting erection was 4 hours? Not some middle aged man's poor wife, I'll bet.
There isn't enough blood to maintain both heads for more than 4 hours. Sorry, it is a curse of biology.
/And thus shows the bad wages of decadence.

replication errors will increase at an even faster pace when senile cells are re-activated to a post-juvenile state. (cross ref: intercalated errors)
the cancer states will be sledge hammer fast and brutal....

It was akin to Pamela Anderson getting even bigger tits.
It was akin to my putting two gym socks in my underwear.
It was akin to Joe Klein taking a shower.
It was akin to getting ones rest and eating right.

If you think the deficit is large now, just wait until people start living to 300. "Uh-oh" doesn't begin to describe it.

This needs to be expensive. Want another 50 years? Save up some cash for it. Cash in that IRA or 401k.

At some point, sooner or later, technology answers some hugely important questions for an individual. Rationality makes it desirable to make the technology scarce and expensive: until it's not.
Enter the plutocrat. Unless power is "reserved to the States respectively, or to the people", we are where we are.

One thing I've learned from my recent medical adventures is that everything. including life, "causes cancer". It's *kind of* bullshit.
Whether it's stem cells or telemorase editing, anything that affects cell growth affects cancer. "Causes" is the wrong word, because the telemorase experiments seem to increase the risk of cancer (be aware that a lot of lab mice are bred specifically to easily develop cancer).
The problem comes when you get a 1.1 RR factor on a 5% increase in cancers in a species bred to develop cancer, and a researcher tells a reporter that the treatment "causes" cancer.
Also, doctors are freakin' paranoid about cancer. I think lawyers have something to do with that, but there you go.
Me, I'm looking forward to some of the better life-extension technologies. Fair warning, if they don't sell it, sooner or later I'll steal it.

I think it's neat, but it doesn't really advance anything yet (still just mice). Wait about 20 years and see if they're hawking it in doctors' offices.

Quoth Aubrey de Grey on Facebook:
Spectacularly oversold. The mice are broken in one very well-understood way (no telomerase, so eventually over-short telomeres), and they have been constructed so that that problem can be fixed with a drug, and lo, lots of the downstream consequences of the problem are also fixed. Duh.

Sci-Fi treated this issue many decades ago. If you get to practical immortality there are only several possible outcomes. One is the population overruns the planet. Another is a select population retires from the world behind shielded cities where no births are allowed except a one-to-one with a death. There are some variations on those themes. One variant is - who is going to choose who gets the treatment? If you think the "it's not fair" crowd is a pain in the ass now...
So then.... quasi-immortals. What could possibly go wrong with that?
