Scientists can lengthen them in the lab but not in vivo. And our bodies lengthen them with telemorase reverse transcriptase but it's pretty much only expressed in stem cells as far as I know.
I'm sure one day someone will try to come up with a viral vector to insert an inducible copy into mature cells or something like that (assuming research ends up showing it would be beneficial). That's usually how the zombies start though so there's always that to consider.

Although I'm still a little skeptical until I see the results published in a journal
Transient delivery of modified mRNA encoding TERT rapidly extends telomeres in human cells, John Ramunas, Eduard Yakubov, et al., The FASEB Journal, doi: 10.1096/fj.14-259531, published online 22 January 2015, abstract
That being said, I'm still skeptical as far as the overall implications. Cell biology is so unbelievably complex that, even when it seems like there's one major trigger or mechanism, that's very very rarely the case. And there's so many potential downstream effects and unintended consequences that it's hard to see this ending up having a real clinical application unless it's very specific to a certain disease. But I couldn't imagine it ever "reversing aging."

Damn. Good find with the article 
I'll have to read it after class today

I don't think time travel is possible simply because what happens if you go back in time and kill your grandfather, thus preventing you from being born, which means you never go back in time to kill your grandfather.
I can see maybe going to the future, but not going to the past.

Let's say you do travel back in time to kill your grandfather. Maybe you are then just trapped in a parallel universe where you don't exist.
The multiverse concept fascinates me.

scientists have confirmed that on the quantum level time travel occurs both forward and backward, so essentially it's possible.

Spacetime flows in only one direction. It's possible, and is easy to demonstrate, to go forward in time. However, it's a one-way trip.
For example, if one of an identical-twin pair travels into space, he is now younger than his brother who stayed on earth. That's not reversible.
Travel into the past is theoretical and is without any demonstrable evidence.

Time travel actually already happened.
The Rant used to be a quaint little website full of good cheer. A good time was had by all. Some dipshit (I think a UAB fan) traveled to the past and put in a thread about how LSU sucks monkey balls - and Whammo! - here we are.

ETA: New stuff from a Stanford lab. Pretty cool but probably a long long way from any kind of clinical application.
Yeah, I agree. Cell biology is ultra complex.
However, the promise of this type of research is incredible:

“This new approach paves the way toward preventing or treating diseases of aging,” said Blau. “There are also highly debilitating genetic diseases associated with telomere shortening that could benefit from such a potential treatment.”
I'm sure you're familiar with the story of Henrietta Lacks and her cervical cancer cells that have been kept alive for 64 years since her death in 1951. It's fascinating that these "HeLa" cells have been used in 70,000 medical studies around the world.

You can't change the past. Whatever happened happened.
OR
Alternate Universes. One in which 9/11 did happen and one where it did not.

quote:Yea her story and all the ethical arguments raised by the family are really interesting. But damn, I didn't realize HeLa had been used in that many studies. I actually didn't know they were used in making the Polio vaccine either. The impact that she has had on humanity just through research involving her cancer cells is amazing. Definitely stirred up a lot of ethical stuff too but that's a whole other topic.

I think time travel would be dangerous as hell. First if you go back in time, you are likely to be immediately identified as "not from around here". In 15th century England, that would mean immediate arrest, probable assignment of local crimes that are unsolved, and execution. Especially if your knowledge of basic facts as common as the button, or any medicine would identify you as a probable witch.
There are a few books around about life in the middle ages and after. Those societies are so closed because of lack of travel and technology that ANYTHING different was subject to strong scrutiny.
Very hazardous environment the moment you attempt to communicate with a local. even in English (now vs then)

This gets me thinking.....if we became 4th dimensional beings, would we weigh more or less? this could work in a girl's favor.

it could exist right now. think about it if the government had that technology do you think they would tell us about it? just the info that time travel exists is Extremely Dangerous! What if Isis got there hands on it or Kanye? 1st Churches of Beyoncé Everywhere!!! :0

Isn't that the plot to the TV show Fringe?

Do you think there will ever be a way to do it? You know (don't know but probably) we spend tons of money trying to figure it out.....
Yes ... but it will be a residual discovery in the process of trying to reach the speed of light in our attempt to travel the universe and/or venture through a found wormhole, etc.
We'll probably discover teleportation first because it is key to time travel ... a "first step," if you will.

The closest we will ever come to time travel in our lifetimes will be any of us getting blackout drunk for 24+ hours and losing a day. Time is a perception.

I've actually time-traveled a few times then in my younger days ... oh, and once after the loss to Mizzou while I was down in Santee cat-fishing and deer hunting.

Oh yeah, the Henrietta Lacks ethical debate is a huge one. Some argue that since cells are a part of us, that she is not really dead.
But the whole ethical debate of using her for the betterment of society is a huge issue. Effectively they let her die for research.
