Will Our Generation Overcome Old Age And Death?
On one of Texas’s sunny days, when a molecular biologist, Meng Wong, went to his work lab, he never came to his mind where he was waiting for him: tens of thousands of worms were flocking in different boxes. As he threw his eyes into the box, he began to reveal the truth to him. What he saw could truly be the heaviest pain on humanity: aging.
Diseases associated with aging, such as cancer, rheumatism and Alzheimer’s disease, kill up to 100,000 people per day, but more and more scientists believe that the situation should not be this way and that finally there should be some options.
Recently, the BBC has conducted a survey of some renowned researchers on the nature of “aging” and the latest advances in the world of science for its treatment (from homophobic microbes to 3D-generated organs).
Teeth that do not fail
The aging mean? If you could look at the molecular world, you could see small but increasing amounts of cellular degeneration that are rapidly transmitted to the cells, tissues and adjacent members. This devastation goes so far as to eventually accumulate the whole of the organism as a result of the destruction and death.
Danish physician Dr. K. Kristensen explains:
The day when we can no longer recover from our recovery, aging begins.
Christensen worked for many years as a doctor until one day he concluded that he had already cured enough patients. He now runs the Danish Center for Aging Research, a place where he tries to stop people from becoming sick early in life. He points out, “We have made some progress.” In the mid-nineteenth century, the average life expectancy in the world was around 40 years, while now in the northern parts of Europe, it has reached a dazzling average of 80 years, and the rest of the world is approaching this mean.
This extraordinary progress is due to the reduction of infant and child mortality, rather than the real increase in the lives of humans. However, there has also been another change that should not be overthrown. Christensen says:
Today, people are getting older in a better state of health, and a simple proof of this is “teeth.” You clearly see that every decade, the health of the elderly’s teeth is better and better.
He says teeth can be a standard for public health. Their condition directly affects our ability to eat properly and nourishes properly. Their proportions can show if other parts of the body are in good condition. Christensen believes people, not only with older teeth but also even have higher results in intelligence tests, a measure that, in his view, reflects the improvement in livelihoods around the world. Better living conditions, better education, better work, etc. all mean better living conditions.
He believes this progress will continue. But for how long?
Current record The longest recorded lifetime in the world belongs to a French woman named Jean-Louis Culman, who lived until the age of 122. An interesting point is that he died in 1997, more than 20 years ago. Since then, the world has seen a lot of changes.
Printers that produce organs
Bvhmyk insulting a Bglvr Zystfyzykshnas, and most members of his family in India was a doctor. He recalls that his father or his uncle at the dinner table talked about patients who could not be saved. Whenever he asks why they cannot prevent death, his father replied that they were doing everything they could, but medical science also had its own limitations. Bohemia remembers:
I did not become a doctor, but I still wished to be the one who made the medicine.
He says the cause of death in aging is often related to the inefficient functioning of vital organs such as the heart, lungs, or liver. If patients could receive a healthy organ from a donor, then doctors like Bohemian’s father could have given people a chance to live again, but things do not always go as we want.
The problem is that the number of people in need of these organs is always higher than the donors. Elderly people around the world are always in long queues for a new kidney or heart, but finding a suitable item is difficult. In many cases, the applicant will die before he receives a member. Bohemia thought what could be done instead of waiting for a donation member? This question was preceded by the fact that he began his efforts to print functional organs, the organs that the patient’s body would never reject. He says:
Let’s assume that you need a liver, and the results of CT scan and MRI also show the exact size and shape of your limbs on a computer. You can give this template a 3D printer and print an artificial prototype of your body of the same size and shape.
However, instead of using conventional ink cartridges, Bohmyk’s equipment uses spontaneously from proteins and cells, but certainly not every cell, but only the patient’s own cells. This means that the probability of a new member being removed from the patient’s body is very small.
His team was also the first to create the first artificial human tissue in India; the next step is to increase the dimensions of the work and produce a small foreign liver; a point we will find from the Bohmic point of view in the next five years. He imagines this foreign limb as a small device outside the body that one can move it with. Within eight to ten years, he expects to arrive at his favorite bench: the point at which a full liver can be produced and planted in the patient’s body.
But does having a defective member does not mean that the organs are approaching the end of their useful life? What if the heart and lungs also get out of work?
Bohemia believes that each of these cases has a different story. He says:
If you change the organ that is the main cause of the patient’s death, the patient may end up in another 20 years. The reason is that perhaps his only defective member of his body was his liver, not his brain or heart.
We ask him to guess how much our lifespan could increase. In response, he said, considering these methods, if you were born in or after the 80s (or 60s), you might well have a chance to live up to 135 years.
The germs that make life lasting
Grandmother Wang died at the age of 100; she was healthy and sweaty by the end of her life. He was still older when he saw that his grandmother was in good health, thinking about the secret of this aging.
Wang is now a molecular and human geneticist at the University of Bailer College of Medicine from the United States, where he performs his experiments in one of the most exciting fields of medicine: the microbes that coexist with us. He explains:
These creatures are micro-organisms that live peacefully with us, from the inside of our digestive system to the skin of our bodies. They are almost everywhere.
You can not see them with their unprotected eyes, but these symbiotic germs take us all. Most of the population consists of bacteria, but beside them, fungi, viruses, and other germs are also present. In the past, scientists did not pay much attention to this microscopic world, but now we have seen their tremendous impact on our bodies.
Recent studies show that our symbiotic microbes are another member of our body. They can influence our behavior and even our response to various drugs. Wang says:
Sometimes these germs make us sick; on the other hand, they play a very important role in staying healthy.
He intended to figure out if these symbiotic germs could have an effect on the process of aging. To discover the truth, he began his experiments on a particular type of worms that lasted only two or three weeks; this seemed to be suitable for life-like experiments. His question was, what happens when microbes change the coexistence of a worm? Can the cream last for longer?
Wang chose one of a variety of bacteria that lived in the belly of this worm and tried to genetically manipulate these bacteria to create new species. Then these new bacteria are fed into a separate group of worms. Three weeks later (when all the worms were expected to die), he went to them. Wang remembers this:
I was very excited, because in some cases it was seen that the animals were still not dead. When we went to them, they were still alive.
I was flopping up and down. What I saw was quite beyond expectation.
Older worms usually exhibit significant reductions in their physical activity, but those who lived with new symbiotic germs, not only grow older over the ages but also had a lower chance of getting the disease. Wang has already begun experiments on mice to see if the change in the coexistence of microbes in these animals will similarly increase their longevity.
It’s not a matter of mind that one-day doctors can prescribe pills that have such a function even for us. This time, asking our question from Wang that this therapeutic approach can, to a large extent, be effective in increasing our longevity; Wang replies:
Some of my colleagues believe that people will be able to live for 200 or 300 years, but I think 100 years is also a good number.
Cells that do not get old
When your age rises, a strange thing happens. As the cells age, they begin to divide, but this process is not always perfect. The more frequent the splitting of a cell, the more likely it will be that that cell becomes what we call “aging.”
The cells that reach this stage are really old and have reached the end of their life cycle, but instead of dying, they also remain and communicate with the cells around them in the face of destructive behavior. This can bring many problems. Lorena Harris, a professor of molecular genetics at Exeter University in England, said:
It’s almost like the cell says I’m an old cell, and you have other cells in the same amount of time that I’ve spent, so you must be old.
These older cells begin to infect other cells, and as we become older, more cells become aged until one day our entire body is filled with these cells. Harris may find in his lab a way to confront these aging hooligans. A long time ago, he stated that one of his fellow researchers had tried to test some chemicals on old-skin cells to see what was happening. In order to determine the age of skin cells during the test, they used a specific color; thus, the cells became aged, and they were dyed blue. Harris says:
I expected the cells to continue to look blue and look old and aged, but that was not so. It was as though a young man had returned to them.
He could not believe this conclusion; therefore, he asked his trainee to repeat the experiment. Every time he repeated the experiment, he again faced the same results, and Harris again asked him to repeat the experiment. Harris recalls that the researcher repeated the experiment about nine times, until one day it came to the conclusion that perhaps something new has probably been discovered.
The experiment has been effective in restoring old cells and transforming them into young cells. This was the first test that reversed the aging process in human cells. Some people suspect that this discovery could be a secret to a longer life. Since then, a flood of phone calls has come from investors and scientists from all over the world.
But Harris is still not sure how much longer life can be. He believes that humans now have the longest lifespan. However, he hopes that these studies will lead to the production of a new generation of drugs for diseases such as dementia or cardiovascular problems. Harris continues:
I hope we can achieve a treatment that simultaneously affects several diseases; thus, people who were supposed to lose their lives at an early age can reap the benefits of a natural lifespan.
Let’s go back to this fundamental question: How long can we live?
Perhaps one day we will be able to replace our injured organs and use supplements that are rich in rejuvenating germs and prevent the aging of our cells.
How many years can they all add to our lives? If, as predicted by Bohemia, we were born from the lucky 60s of the 60s or later, we might be able to reach the age of 135. When we arrive at this age in 2116, who can imagine what other capabilities will await our generation?
