"I think it will be completely possible to revive her." Cryonics is the practice of deep-freezing recently deceased bodies (or even just the brains of those who have recently died) in the hopes of one day reviving them. It has been the subject of serious scientific exploration and study - as well as a fair share of pseudoscience, lore, and myth. Fictional accounts like Batman's Iceman, and the (untrue) rumours of Walt Disney being cryogenically frozen have cast a speculative shadow over the field of cryonics. But recently, for the first time ever in China, a woman has been cryogenically frozen. Zhan Wenlian died at the age of 49 from lung cancer and her husband, Gui Junmin, "volunteered" her for the cryonic procedure. Both he and his late wife wanted to donate her body to science to "give back to society." He told The Mirror UK that he was initially "pitched" the idea of cryonics with it being described as a "life preservation project". This procedure - which has Wenlian's body resting face down in 2,000 litres of liquid nitrogen - was completed at the Yinfeng Biological Group in Jinan. This project is the collaborative effort of the Yinfeng Biological Group, Qilu Hospital Shandong University and consultants from Alcor Life Extension Foundation, a nonprofit cryonics company based in the United States. Even with all the faith many have in the procedure, the question remains: how scientifically possible is a project like this? Is this just an experiment to allow us to better understand human biology, or could cryonics one day become a feasible option? Cryonics is all about timing. The bodies of the deceased are cryogenically frozen immediately after the heart stops beating. "Freezing" is a bit of a misleading term, because cryonic freezing is actually very specifically trying to avoid ice crystal formation - which damages the cells of the body's tissues. Rapid cooling, rather than freezing, is a more accurate description of the process. A chemical cocktail of preservatives like glycerol and propandiol, in addition to antifreeze agents, are commonly used to get the body into a stable state where it won't be decaying, but also won't suffer damage from being stored at low temperatures for, conceivably, a very long time. From there, the bodies are given specific care that caters to the idea that death is a continuing process; one that can ultimately be reversed. The aim of cryonic preservation would be to one day be able to thaw the bodies and reanimate them at a cellular level - preferably without too many epigenetic changes. "I tend to believe in new and emerging technologies, so I think it will be completely possible to revive her." With our current understanding and technology, this process of reversing death so completely is just not possible. The closest kind of revival we have are the moments after clinical death where patients are revived by something such as cardiac defibrillation. Cryonics acts within this critical, albeit brief, period as well - but works within the belief that death is a grey area. More of a process rather than a definite, final, event. Just because we haven't succeeded in reviving the dead yet doesn't mean the field of cryonics is unnecessary or unimportant. This case in China is a step forward for everyone researching the field of cryonics - and those of us who hope to benefit from advancements in it. We may not be able to reverse death just yet, but it doesn't seem out of the realm of possibility to imagine that, with such wild scientific advancements underway, technology could one day allow it to be possible. Whether or not it does in our lifetimes, this most recent development is certainly an interesting one. This article was originally published by Futurism. Post Comment Private Reply Ignore Thread
