A breakthrough paper, in my opinion. :) Read the entire thread. It's well worth it.



An TIME article about this paper. https://time.com/6246864/reverse-aging- ... milestone/

Scientists Have Reached a Key Milestone in Learning How to Reverse Aging
By Alice Park

In the Cell paper, Sinclair and his team report that not only can they age mice on an accelerated timeline, but they can also reverse the effects of that aging and restore some of the biological signs of youthfulness to the animals. That reversibility makes a strong case for the fact that the main drivers of aging aren’t mutations to the DNA, but miscues in the epigenetic instructions that somehow go awry. Sinclair has long proposed that aging is the result of losing critical instructions that cells need to continue functioning, in what he calls the Information Theory of Aging. “Underlying aging is information that is lost in cells, not just the accumulation of damage,” he says. “That’s a paradigm shift in how to think about aging. “
Just wow. Now I'm starting to think it will be definitely possible to reverse at least some aspects of aging in our lifetime. :shock:

I wish one of these scientist would do the right thing and start human trials on themselves. The benefits if they can pull off would probably be will worth it.

World's oldest person, French nun Sister Andre, dies aged 118

17 minutes ago

The world's oldest living person, French nun Lucile Randon, has died aged 118.

Ms Randon - who assumed the name Sister Andre when she took holy orders in 1944 - died in her sleep at her nursing home in Toulon, France.

Born in 1904 in southern France, she lived through two world wars and dedicated much of her life to Catholicism.

"Only the good Lord knows" the secret of her longevity, she told reporters.

Born when Tour de France has only been staged once, Sister André also saw 27 French heads of state.

Study Finds Hypertension Drug Could be Repurposed to Delay Aging
January 23, 2023

Introduction:
(Medical Xpress) Researchers have found that the drug rilmenidine can extend lifespan and slow aging.

Published in Aging Cell, the findings show that animals treated with rilmenidine, currently used to treat hypertension, at young and older ages increases lifespan and improves health markers, mimicking the effects of caloric restriction.

They also demonstrate that the healthspan and lifespan benefits of rilmenidine treatment in the roundworm C. elegans are mediated by the I1-imidazoline receptor nish-1, identifying this receptor as a potential longevity target.

Unlike other drugs previously studied for this purpose by the researchers, the widely-prescribed, oral antihypertensive rilmenidine has potential for future translatability to humans as side-effects are rare and non-severe.

To date, a caloric restriction diet has been considered the most robust anti-aging intervention, promoting longevity across species. However, studies of caloric restriction in humans have had mixed results and side effects, meaning finding medications like rilmenidine that can mimic the benefits of caloric restriction is the most reasonable anti-aging strategy.

Anti-ageing gene injections could rewind your heart age by 10 years
https://www.telegraph.co.uk/news/2023/0 ... -10-years/
Healthy mutant gene in super-fit people can reverse the decline of heart performance in the elderly, according to a study
By Sarah Knapton, Science Editor 23 January 2023 • 5:10pm

Injecting the genes of so-called “super-agers” into failing heart cells regenerates them, making them function as if they were 10 years younger, scientists have found.

The discovery opens the door for heart failure to be treated or prevented by reprogramming damaged cells.

Researchers have long suspected that people who live beyond 100 years old must have a unique genetic code that protects them from the ravages of old age.

Previous research showed that carriers of a variant of the BP1FB4 gene enjoy long lifespans and fewer heart problems.

In new experiments, scientists from the University of Bristol inserted the gene variant into a harmless virus and then injected it into elderly mice. They found that it rewound the heart’s biological clock by the human equivalent of 10 years.
