Scientists succeed in reversing biological aging

In a world-first study, the biological aging process has been reversed in a group of elderly volunteers.
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.

This however could be set to change thanks to a recent scientific study that sought to reverse two key indicators of biological aging - telomere length and senescent cell accumulation - through a process known as Hyperbaric Oxygen Therapy.

The research, which was carried out by scientists from Tel Aviv University and the Shamir Medical Center, involved placing volunteers in a pressurised chamber where they were given pure oxygen for 90 minutes, five days a week for around three months.
Incredibly, after the trial had finished, their telomere length and senescent cell accumulation was found to be equivalent to that of someone 25 years younger.

"Since telomere shortening is considered the 'Holy Grail' of the biology of aging, many pharmacological and environmental interventions are being extensively explored in the hopes of enabling telomere elongation," said study co-author Shai Efrati.

"The significant improvement of telomere length shown during and after these unique HBOT protocols provides the scientific community with a new foundation of understanding that aging can, indeed, be targeted and reversed at the basic cellular-biological level."

What these changes may mean for the day-to-day health of the participants however remains unclear.

Yet you would start a business on it from a single article? Seems a tad premature don't you think?

I have looked at the papers and the study doesnt reverse aging by increasing the oxygen supply to a patients cells, but rather by inducing hypoxia. That is low oxygen levels, in case people get the wrong impression from reading the article. The treatment lowers a persons oxygen levels for 90 minutes a day over a period of several weeks to clear out a lot of senescent cells and extend telomere length. The HIF genes upregulate when oxygen levels are low to kill of cells so that a person can survive on the reduced oxygen availability. They also kill cells when we die (aka, our circulation stops r...

Well there is no way Im doing all that... I choose death.

Not new on the planet here. If they ever do get an effective anti- aging process it will cost, at a minimum, $100,000 per month.

That would make pretty poor business practice (blocking out 95% percent of your customers lol) and run contrary to how technology works historically. New tech starts high and gets cheaper as it goes. Like with cars, computers, phones, etc. Hyperbolic chambers currently cost 8-20k to buy right now so it would be odd for such a price jump. A competitor could easily undercut you with a cheaper price.

Although we all would like to live longer and better perhaps but that would be a mistake for the survival of the human race. This would most certainly quickly increase the population of the planet and what we need to do to survive is to reduce our populations (and quickly) The planet cannot support more people.

With that logic we should never of made any advances in the medical field . Doomers thought we were going to all starve on the industrial age due to population growth. But then we ended up just innovating ways to produce more food then ever before.

If your useful they will keep you alive longer.
