Scientific quest for immortality

11 Apr

ScienceSearch for the Ponce de León fountain of eternal youth may be a legend, but the basic idea – find a cure for old age – is very real.

People have been trying to crack the code of eternal youth, almost from the beginning of mankind.We tried everything we could imagine from the magical objects and an epic journey to the sacrifices and the use of blood also invented monsters that live forever, drinking blood. There was only a matter of time when science got involved in this quest Mysterious, and, you know, some real steps in this direction, she will be able to do. The Scientific quest for immortality Aging at the molecular level, it makes no sense. Our bodies are constantly creating new cells and restore our natural ability to protect, but we’re still getting old. Entropy takes the best of us, and we accept it as inevitable, although science has made a huge step forward, increasing our life expectancy.

Over the last century, life expectancy has increased, and people in developed countries can live for about 80 years, which is much more than 47 years in 1900. This increase is due to greater advances in treating childhood diseases, but it also led to an increase in chronic Mysterious diseases in old age. Heart disease, cancer, Alzheimer’s disease – a serious problem, and each one is treated individually, or not treated at all. It would be much easier to just swallow a pill and strengthen the body’s resources.

Scientists are well aware of these problems and constantly test different methods to restore the viability of the human body. Restoration of homeostasis Mysterious – or the body’s ability to stabilize its own system in response to stress, such as exercise, hot or cold weather, high or low light – this is the main direction. The human body – is primarily a complex biological machine, and old age – is, in fact, a mechanical problem that must be addressed.

And if the solution to this problem is to keep people healthy and free from disease as long as possible, then science is very good chances to cope with this.

The biggest villain who prevents us from living a long time, is the enzyme telomerase. Open Dr. Elizabeth Blackburn (who received a Nobel Prize for his discovery), telomerase repeat DNA sequences at the end of the chain of chromosomes that cover every chain and determine the beginning of the next. It is responsible for reporting to our cells when to stop growing, and every time the chain cover, a small piece of information about the cell how to rebuild lost. As a result, scientists are looking for ways to prevent loss or activate telomerase, when she cannot fight aging at the molecular level.

Nevertheless, science does not always know what the problem is telomerase, so throughout the history of science offers other solutions. Aviator Charles Lindbergh tried to cheat death in a way to replace our bodies machines, like those doctors use in modern medicine for the temporary replacement of the lungs. Cloning, cyborgs, Nanotech cell renewal and 3D-print media – a continuation of the line of thought Lindberg, which can hardly be called incorrect. In any case, all these techniques rely primarily on the replacement of parts of the body, but not to stop aging.

Worm-hole Science fiction writers often offer download human brain into a computer and thus achieve immortality, and real-world science says that this is quite possible. The so-called “whole brain emulation” will allow scientists to take us on this form of immortality, and further create neural device that will work with the human body as well as our brains, and thus create a “perpetual brain.” Science fiction also prompted us an idea of cryogenic preservation of the human body by slowing metabolism and conservation of resources – simply put, freezing. But this measure is more protective than solving the problem.

Current research Scientists, University of California at San Francisco successfully drew the effects of aging and diseases of old age in mice infused blood of young mice in the old. In particular, they found that the blood of 3-month-old mice reverses age-related memory loss, learning and brain function in 18-year-old mouse (equivalent to 70-year-old man). Scientists have also found that when they injected the plasma only in old mice are increased endurance and motor function, becoming with her 3-month peers on the same level. Scientists have even been able to identify a chemical signal, a specific protein, which acts as the primary regulator of brain activity which increases with young blood. However, the fact that there is no specific mechanism or a drug that will solve all the problems of aging – and some scientists plan to find when they start to experiment with people.

Silicon Valley – the main center of scientific papers on aging. Google has created Calico Labs, to take back the aging treatment and a cure that will help our biology. Human Longevity focuses on creating a database of 1 million sequences of the human genome in 2020 to improve the quality of anti-aging. Awards Palo Alto Longevity Prize, each about 500 000 dollars, was awarded for Innovation in restoring the homeostatic ability of the body and promoting the extension of the stable and healthy life.The stated goals of all such companies – to develop methods of dealing with aging and diseases of old age specifically, but in fact they all bring us closer to immortality.

Why Silicon Valley is involved in this?one of the pioneers of the industry, believes that a successful medicine for anti-aging has the potential to become the largest industry ever existed with major opportunities for profit.
