This isn't new. The Notho research found that RNA level change with age and this correlates with protein aggregation. I think these protein aggregates can be cleared, and the RNA levels restored to be more like a youthful state -- we have shown this in Nothos. But I am not sure this is really reversing aging. I think this is more like giving the car a good cleaning (inside and out) but it doesn't really restore the car to something newer. It just looks better and runs better but with each day you are getting closer to a critical part failure. In my work, by fasting, we cleared out the senescent cells from the tissue but a few weeks later there was no difference between the fasted and normally aged fish. The DNA damage driving aging is still there and the protein aggregates will come back. There is now a lot of epidemiology work showing that regardless of our best efforts all lifespan trajectories converge at about 120 years of age. The difference is whether we die slowly or quickly -- the slope of the survival curve is either shallow or steep. Carry on keeping your body in good working order and you can expect to get closer to 120 years than those who don't.
