Artificial blood factories, growing GMO hearts, injecting stem cells into the brain, putting a person into a state of suspended animation … Medicine is gradually realizing the wildest dreams of science fiction writers about human immortality.

Bonic hand

The average life expectancy of a person is constantly increasing with the development of medicine and new technologies. The fight against cardiovascular and other diseases dangerous to humans, the creation of artificial organs and limbs can, in the end, realize the long-standing dream of mankind - of physical immortality.

Blood factories

Blood transfusion has saved the lives of so many people. However, there is a constant lack of blood donors, and besides, not all blood is suitable for every person: only a certain group is required, otherwise the immune system attacks foreign cells.

Scientists have recently found a solution: for the first time, they managed to create artificial blood in the laboratory, moreover, of the universal group O, which will suit anyone. This discovery may lead in the future to the end of the donation institute and to the production of blood on an industrial scale.

Growing body parts

From the realm of science fiction, growing body parts in laboratories has already become a reality. Women, whose reproductive and genital organs were underdeveloped from birth, were transplanted with artificial genitals produced in the laboratory from their genetic material. Within eight years, the new organs have taken root completely without any side effects.

Also, people who have lost parts of their nose due to skin cancer have received new laboratory nostrils grown from their own skin cells.

Restoration of functions of paralyzed limbs

Injuries to the spine can lead to paralysis of a person's limbs, up to most of his body. However, when studying the effect of electrical impulses on the nervous tissue of the spinal cord, specialists made a breakthrough in medicine: they managed to restore the mobility of previously paralyzed parts of the patient's body using targeted electrotherapy.

Together with traditional physiotherapy, the method of processing spinal cord tissue with electrical signals promises many wheelchair users with hope for the restoration of lost body functions.

Young blood

Chemicals have been found in the blood of young organisms that can slow down the aging process. Three independent groups of researchers came to such a similar conclusion at once, conducting experiments on mice.

By transfusing blood from young to old, experts have noted significant improvements in memory and cognitive abilities in the latter, as well as endurance and muscle strength.

So it is quite possible that Countess Elizabeth Bathory, who used the blood of young virgins for rejuvenation, was not mistaken in her calculations. In the next few years, researchers are looking to conduct similar trials on older people. If successful, it is quite possible that many will be able to postpone the approaching old age for a long time.

Genetic monitoring

Whatever miracles modern medicine promises, many people are unlikely to get rid of laziness and neglect of their health. But many deadly diseases can be eradicated in the bud if you see a doctor in time.

Perhaps, in the future, this problem will be solved with the help of an electronic system, which, through microscopic sensors on the human body, will monitor his physical condition, give him recommendations, warn him in time in case of a disease in the body. The development of such systems is already in full swing by the best researchers.

GMO pig heart transplant

Cardiovascular diseases are the leading cause of death in almost all developed countries of the world. There are often cases when an operative heart transplant could save a person's life.

However, donated hearts are extremely rare, and heart-lung machines are only a temporary solution. To date, there has not yet been created an effective human-implantable whole-heart prosthesis.

This problem can be solved with the help of pioneering developments in the introduction of human genes into pigs. A heart transplant of a GMO pig has already been done to a baboon, who has lived peacefully with the new organ for over a year.

Therefore, the likelihood that humanity in the future will have access to an almost unlimited number of donor hearts (albeit very expensive) from pigs with human genes is very high.

Rebuilding the brain after a stroke

Stroke is another killer disease that claims millions of lives every year. But even if apoplectic stroke does not kill, it can render a person disabled. After a stroke, people often lose the ability to fully control their own bodies, and their mental abilities also suffer.

More recently, however, medicine has found a way to help stroke victims. By injecting stem cells into the brains of patients, the researchers were able to restore the lost abilities of the victims. After therapy, patients were able to move their limbs again, control over which they had previously lost, and perform their usual actions.

Heart from a 3D printer

3D printing is gradually entering our lives, with the help of it you can make the most intricate parts and finished products. A team of specialists from the University of Louisiana even managed to print the working components of the human heart using fat cells and collagens.

Experts expect that over the next 10 years, hearts and other organs of the human body will begin to come out of 3D printers, much to the delight of doctors and patients.

Bionic limbs

Prosthetics also does not stand still. People who have lost their arms and legs as a result of accidents or illness may soon cease to feel disabled.

Modern bionic hands, for example, from the DEKA company, are already complex technical devices that can be controlled directly by signals from the brain of their owners.

Prosthetic limbs easily button up and unfasten the buttons on the jacket, take eggs without breaking them. Who knows, maybe one day with their help it will be possible to perform virtuoso passages on the piano?

Anabiosis

The idea of ​​putting a person into a state of suspended animation and then bringing him back to life has been in science fiction for several decades. However, very soon it can become a reality.

Peter Rea already conducted a number of similar experiments on pigs back in 2000. Their blood was replaced with cold saline solution, which “froze” the animals' organisms. Then the pig was brought back to life.

A team of researchers from the University of Arizona is looking for the first human candidates to test the new technique. After these experiments, the very definition of death may change, scientists say.
