All living people hope to see many wonders of science during their lifetime: some want to go into space, others want to see advanced, perfect robots with their own eyes, others dream of merging with electronics themselves and so on. However, "magic pills against aging" or other methods of regeneration want to find everything in this life.
Biological aging can be considered as a progressive decline in the functionality of the body, which results in a bunch of hundreds of diseases typical for old age. Modern molecular biology has identified hundreds of different causes today, each of which individually causes aging in tissues, but the result of all these problems is a rather sad fact: the accumulation of old and non-functioning cells in tissues.
The presence of spent elements in tissues is a problem in itself, since old cells take up space for new cells that could appear in their place, pull oxygen and nutrients, divert some of the power of the immune system to destroy itself, and so on. However, the most important thing that biologists have discovered only recently is that aging cells release packets of special signaling molecules that not only enter young neighboring cells, but also spread throughout the body.
The effect of these signaling molecules is not fully understood, but in general it is negative, totally accelerating the cell cycle and forcing young cells to age faster. Therefore, when a critically large number of old cells are collected, the body goes through a kind of "point of no return": a huge volume of old cells makes the entire body aging. But it seems that this problem itself has become the key to its solution.
According to Technology Networks on August 20, a very simple experiment by American molecular biologists allowed everything to return to its place in cultures of old, dying tissues. Quote:
So the solution to activate dying cells is a simple, readily available volcanic gas called hydrogen sulfide. Water saturated with this gas is a traditional feature of very, very many resorts. The staff of these establishments, in general, knows little about hydrogen sulfide, clogging their ears with the traditional "blah-blah-blah" about the "general healing effect."
However, now, thanks to the study of enlightened adepts, the biological mechanism of this gas is almost known today, and in anticipation of a further biological breakthrough, people can already fight age on their own.
