Scientists reverse the aging of human cells

Researchers in the UK have achieved a significant milestone in their quest to reverse the aging process.
Mankind has been obsessed with gaining immortality for thousands of years, but even despite the incredible advances in science and medicine achieved over the last few centuries, our species still remains just as vulnerable to the aging process as our ancestors were millions of years ago.

Now though, in a new study, researchers report that they have managed to reverse aging in old human cells by delivering hydrogen sulfide directly to the mitochondria.

The technique appears to stop the cells from reaching senescence - the point at which division stops.
"We still don't fully understand why cells become senescent as we age, but damage to DNA, exposure to inflammation and damage to the protective molecules at the end of the chromosomes - the telomeres - have all been suggested," the study authors wrote.

"More recently, people have suggested that one driver of senescence may be loss of our ability to turn genes on and off at the right time and in the right place."

While we are still a long way from fully reversing the aging process, the breakthrough could lead to effective new treatments for several different types of age-related diseases.

"This is some way in the future yet, but it's an exciting start," the researchers wrote.

Currently there's plenty of room. We could all have a square meter on Iceland. The problem is our consumption.

surely they meanstopping the aging process or slowing down?

I'd like to bet that: a ) It will be ridiculously expensive if and when available, and b ) It won't be given willy-nilly to just 'anyone'. There will be a certain pecking order among the echelonway before your average Joe. Damn, I'm usually void of tin-hat material but this one's got me

Hmmm... May be the movie "In Time" was not all that stupid. People think they have enough intelligence to control population, forgetting meanwhile that procreation is the meaning of life for every species on our planet, including ourselves, and it's burned in every particle of our flesh. It's all about ecological balance, food resources and consumption, that's why cells die. Every species which didn't follow this rule became extinct.

Reversing aging has already been achieved (mainly in mice): 1. Stitch the blood vessels of a young and old mouse together - The young mouse rapidly ages over a couple of weeks and the old one gets younger. Their biological age comes to rest someone in the middle of both ages. Tests are currently underway to try it on humans and it is believed to all be down to the levels of one protein in the blood. 2. Population statistics shows that people who primarily eat younger animals live longer. Some relation to the above? Anybody fancy becoming a vampire? Wait... weren't they immortal in myths? lol. ...

There is overpopulation on our planet now, how could we possibly support a population that never dies? Why would anyone wish to live forever? Look around at the world situations today; it's only going to get worse. More people, more hate.

Let me guess, the person who wants to limit the population is the one that's spreading love; not hate.

I don't know if I want anyone shooting my cells full of H2S. That stuff is highly toxic. It's a strong reducing agent. Since ageing is thought off as an oxidation process, I can see how it can stop the process for a while, but reverse it? If if works, someone will be rich in a very short time.
