Can people wake up after 100 years of freezing?

Scientists can invent non-freezing cold mix technology to preserve mummies for centuries. Current incurable diseases can be cured if humans are given artificial "sleep" by freezing and wake up after science finds an effective cure.

Back in the 40s of the last century, researchers first laid out the concept of freezing people. But, experiments on animals did not achieve the desired results.

A group of Russian scientists have been trying to develop an effective biochemical and resuscitation technology since the early 90s. This scientific team is led by Academician V. Kovanov, Russian Medical Institute. Russian scientists have achieved somewhat remarkable success.

A laboratory mouse was frozen and then warmed up slowly - the result of the animal not dying during the experiment.

But cryoprotectors can only block ice formation in individual cells, ie blood, kidneys, semen or small pieces of tissue. but these substances cannot penetrate the entire body - some areas of the body remain unaffected.

This group of researchers disbanded in 1994 after the death of Kovanov. Later, the leading scientist of the Kovanov group, Pavel Scherbakov, gathered former colleagues to form a new research group.

V. Telpukhov , Professor of Surgery at the Moscow Sechenov Institute of Medicine along with P. Scherbakov pioneered the use of a mixture of inert gases in place of cryoprotectors. Mixtures include argon, krypton and xenon. When frozen, the gases turn into masses like frozen fruit juice, re-forming the solid water without forming sharp ice crystals.

A lab rat was frozen in an inert gas environment at -196 ^o C. The mouse was then released to 0 ^° C. The heart of the rat was eventually transplanted to another mouse and as a result it caught head banged back. The experiment was repeated 10 times.

Russian scientists then copyrighted the method of preserving their tissues and organs at the Russian Patent Office in January 2006. 'Frozen people' stored in the biochemical environment are the final destination of the program. However, the problem still needs to be solved : why not revive the entire mouse while its heart has started to bounce back after a short period of time in liquid nitrogen?

According to Pavel Scherbakov, inert gas bubbles are the biggest obstacle today. The bubbles will rise high in the blood vessels of the mouse when the temperature is raised to 0 degrees and more. The body will produce more gas if helium is introduced into a gas mixture. The problem to be solved is the selection of gas mixture components, pressure and warming speed.

However, the investment in the program has faced legal obstacles in Europe, the US and Russia that can make it difficult to freeze the human body at any time. Until legal obstacles are removed, new researchers can conduct a fully dormant state (anabiosis) of a mammal in the near future.
