“I don’t want to be buried underground. I want to live and live longer and I think that in the future they might find a cure for my cancer and wake me up. I want to have this chance. This is my wish.”
Here are two articles about the case if you want to know more:

https://www.theguardian.com/science/2016/nov/18/teenage-girls-wish-for-preservation-after-death-agreed-to-by-court
So I decided to do some research.
Interested? In Michigan there is Cryonics Institute...
In Scotsdale, Arizona there is Alcor....
http://www.alcor.org/
What do you think? This week rather than asking you to read an article. I am going to let you do the research. You will still write a scholarly paragraph, but you get to do the research. Pick a few questions and answer them, pose your own questions, state your opinion, and be sure to comment on someone else's post.
What is cryogenic preservation?
Is cryogenic preservation done on living organisms?
Is revival even possible?
Can a preserved brain be put into another person's body?
Has any mammal been successfully cryopreserved and revived?
How much does it cost?
What is the neuro option?
Do you think it will be possible to cure every disease, reverse aging and fix the damage from freezing?
Can the brain stop working without losing function?
How soon after the heart stops must the person be frozen?
Cryonics is suppose to offer a second chance at life once you have passed away. To be honest i first thought that this was nonsense and was something I could never see working. But with advances in technology and science, i do see how Cryonics could work some day. The people who decided to be frozen saw this too. Cryonics works be being frozen liquid nitrogen temperatures so the body is preserved and is still in good condition. The goal is to be able to if waking the person back up, there body will stay be in good shape and not having any problems. I looked at the question, “can you guarantee success?” The question to that is no, Scientists can’t guarantee success because they don't know what the future holds. I found out that people who have been deceased for a long time (like Lincoln) have no chance at being revived, although that would be amazing.. It is impossible because their brains have had no activity in such a long time. My opinion on this is kinda in between, it’s really hard to pick a side. The cost for this is $28,00, which is odd because i thought it would be a lot more. I see religiously why cryonics is not a good idea and makes no sense. But then i also can see that in the future this could work and gives you a second chance at life.
ReplyDeleteI love how you kept an open mind, Lindsey!
DeleteI like how you addressed that Scientists can't guarantee success.
DeleteCryogenic preservation is when you freeze someone's body then later revive them from their dying state. As of now the science isn't here to revive these bodies but people are frozen hoping that the technology will come soon. As for the costs it's about $200,000 to preserve your whole body and about $80,000 for the "head only"(neuro) option. I don't think it is possible to cure every disease and fix the damage to the brain as of now. But maybe in the future it will be a common practice to be cryopreserved. If this does become possible i would say that this should be only available to people with deadly diseases, because if this is available to to everyone the world could become overpopulated. Personally i hope the technology comes soon to make this all possible. It could potentially save many lives and would be a huge breakthrough in science.
ReplyDeleteIt is very interesting that you mentioned the idea of overpopulation due to cryogenic preservation, I haven't really thought of that.
DeleteBeginning in 1962, when the idea of cryonics was mentioned in Robert Ettinger’s book The Prospect of Immortality. Cryonics is the process of preserving people at very low temperatures (-320 degrees fahrenheit), so they can be revived in the future. The process of their temperature being lower to said degrees is called vitrification, currently used to preserve human embryos undergoing IVF therapy. As imagined, it’s much easier to preserve and revive 8 cells compared to an entire body, in addition because of the quicker process some companies offer to just freeze the brain, although, the brain would be damaged through cryonics and chemicals the replace blood are toxic. In fact, scientists have preserved a rabbit kidney and then revived it, then put into a another rabbit. This would be pretty neat if we could potentially use cryonics for organ donors. The cost of cryonics is a one time fee of $28,000 at time of death. It might sound like a great idea now, but what if the condition you left the world in isn’t the same when and if you finally return? Even though, I not interested in being buried 6 feet underground I am also not keen of the idea of any part of me being preserved, I plan on dying with no plans of ever being revived. Also, I could list several ways $28,000 could be better spent. No thanks, not interested.
ReplyDeleteI agree with you, I would not be interested either! There are a lot of cons to cryonics and I like how you mentioned those and also how expensive it would be.
DeleteI agree with you, I would not be interested either! There are a lot of cons to cryonics and I like how you mentioned those and also explained how expensive it can be.
DeleteI agree that I have no interest in my body being frozen and used as a guinea pig for this technique, but you do have to appreciate the science and thought behind it. People who lived such short lives could have the potential to enjoy what they didn't get to before, so in that aspect it's pretty cool.
DeleteCryogenics
ReplyDeleteCryogenics preservation is preservation of humans at freezing temperatures. This theory was started in 1962 after Robert Ettinger wrote a book called The Prospect of Immortality. Although this idea of bringing back dead people with modern medicine sounds cool, it is easier said than done. To successfully revive the person you would not only have to cure what killed them but also cure the effects of being frozen for X amount of years and then be able to bring them back to life. Today we are only able to safely preserve egg cells for 12 years, not an a human body with trillions of cells. To freeze humans you have to pump the blood full of “Antifreeze”, which is toxic in itself. Also there are ethical concerns like, Will the person still have their conscious?. All in all, the damage done during this preservation seems too crazy to combat at this time, but I do think it could have some use. If we could learn how to preserve human organs, like scientists did with a rabbit kidney, this far fetched science would be very practical in that sense.
I think that if we were to start using cryogenics, it should be to preserve human organs for people who need them. They are always looking for organ donors, and this would be an efficient way to help this process.
DeleteCryopreservation is “the process by which any living cells, tissues, organs or entire bodies are protected from decay by storing them at extremely low temperatures”. Cryogenic preservation is most definitely done on living organisms. People would want to do this to their bodies because they think that after a long time, science and technology will have figured out a way to revive the bodies, cure what killed them, and then they will bring them back. The 14 year old girl from the U.K. that wants to be frozen has this mindset and wants a second chance at life. It is very expensive, ranging from $28,000- $200,000. The neuro option is cheaper, however, but it is to just have your head preserved, so that maybe in the future they can create a new body for your brain or clone it. Nobody knows yet if revival is possible. There really isn't any way to guarantee that there will be this kind of technology in the future, so we will probably just have to wait. Apparently, there has been a mammal successfully revived. According to Independent, “the minute animal had been collected from moss in Antarctica in 1983, before being unfrozen in 2014”. Japan’s National Institute of Polar Research says that their scientists have succeeded in reviving the ‘tardigrade’ animal which they had collected in Antarctica after 30 years. This is very interesting and makes me think about how technology will be in the upcoming years and who knows, maybe we will regularly be able to revive people and animals that were frozen.
ReplyDeleteYeah maybe we'll be able to revive people, but I wonder what that will do to our population, that persons body, and that persons personality
DeleteCryogenic preservation is the process in which living cells are stored at low temperatures, to slow decay. Cryogenic preservation has been done on many living organisms, including organs of many species, along with an entire organism, the nematode worm. Revival of cryogenically frozen organisms is possible, such as the nematode worm, but research has not gone far enough to revive larger and more complex organisms, like humans. I do not know if it will be possible in the future to cure every disease, reverse aging, and fix the damage from freezing, but I do know that not too long ago many things were considered impossible but they are now possible.
ReplyDeleteCryogenic preservation is a very interesting thing for me. I have heard of it through many movies and video games, but now that I have heard more practical purposes for it I believe it is a great thing. The possibility of freezing organs is a huge fascination for me, as I have been hearing news on preserving hearts. There is a machine created that keeps the heart beating by constantly pumping enriched blood through it, keeping the delicate tissue of the heart alive. If cryogenics enables hearts to be frozen for future use, that will be evening better than the machine, because hearts and others organs could be used for people that desperately need them years later, drastically reducing deaths.
Cryogenic Preservation is the process of packing a body in ice and injecting them with various chemicals in attempt to reduce blood clotting and damage to the brain. Scientists talk about what would happen if we thaw these bodies and they say that cooling a body to -196C makes it very brittle and that the brain is very sensitive to heating and cooling. They also think that these bodies may be at the end of life after illness and ageing has had its effects. I’m not sure if any animals have been brought back to life because of this process, but a rabbit’s brain has been frozen and thawed years later in perfect condition. Scientists say that this could help preserve memories. The next step for them is successfully freezing and thawing a pig’s brain and ultimately a human’s. I think that if we can preserve bodies, that would be really cool, but I don’t see how it’s beneficial. Everyone else you know is already dead and I just personally think it’s wrong. Life seems artificial at that point and I believe that you are born in a certain time for a certain reason and you get certain diseases or die early for a reason. I know that’s very morbid, but it’s also life.
ReplyDeleteI agree when you said about if people would have come back to life using that process then life would be artificial. I also believe that everything happens for a reason.
DeleteI personally believe that something like this is actually possible, but their is not really a way of knowing what affects something like this will have. Scientists have already discovered how to revive animals like monkeys from this state, so they are already almost there. Now, they just need to figure out how to reanimate these animals. At the moment, it is not likely that a brain would be able to be transferred to another person. After cryogenic freezing, there would still be excessive cell damage. The brain most likely would not be suitable to put into another person for this reason, as well as many others. I think that cryogenic freezing is actually a really good idea, even if we do not know if it will work yet. Many people who have terrible diseases often do not have any other option but to do this. It is really cool that they will have a second chance. One thing that I am wondering about is what affect freezing someone will have on there mental state. Will they even be able to remember what there life was like? How will they react to the changes that will occur while they are away?
ReplyDeleteI agree with you that this is possible, but the question is when? How soon will we be able to bring back the dead or save lives and what does that mean?
DeleteI agree that this could be possible but I don't think we will be able to see this in our life time because it would just take centuries of further investigation to know for sure what this really is all about.
DeleteCryogenic preservation is a process why living organisms are preserved and frozen in extreme low temperatures. I think there are too many complications that would come with this when it comes to human brains but I do like the idea of doing this to donor organians. Not only preserving a brain but then putting it into another body, that in itself is near impossible, with having too reconnect all those nerves and the spinal cord. Having this done has never been done before so there's not a distinct price but I imagine the price too get this done is super expensive. It will be interesting to see what the future holds when is comes to the world of science.
ReplyDeleteI agree that there are a lot of potential complications, but I think that with what can come from the research may be worth it because if we can preserve someone with a deadly disease then use this later on as evidence as to how to cure it or how it happened then it could be a huge help to medicine and curing other people.
DeleteCryonic preservation is the preservation of a body at a low temperature (-196 degrees C) of people who cannot be saved by modern medicine so they hope health could be possible in the far future. The procedure costs on average $46,000 because of how hard it is to do and not every country offers it. Currently, revival is not possible and scientists do not know if the cells will still work and function properly after being frozen. There is no evidence that the entire body would survive the transplant. Although, it may be possible in the near future because it is plausible but hasn't been done successfully on a human. Cryonics is considered controversial because of the ethical reasoning like is it okay to bring someone back from the dead. Personally, I believe that we should let nature run its course and die when we die but it still is interesting how scientists are looking into crying and how one day we might be able to cheat death.
ReplyDeleteI agree, this concept is very interesting, but I feel once we die, we should not be preserved. When nature says its our time to go, we should let it happen.
DeleteI also believe we should let nature do it's thing, and we shouldn't mess with what we were all given with. It could possibly have some benefits in the future though!
DeleteAll of this "cheating death" reminds me of Frankenstein!
DeleteI agree. I believe cryonics could really cause problems considering the limited space we have on Earth. However, I do believe that using it to preserve an endangered animal species would be a responsible use of cryonics.
DeleteWhat is cryonics? It's is “the practice or technique of deep-freezing the bodies of people who have just died, in the hope that scientific advances may allow them to be revived in the future” the thought of this idea could be life changing (literally). Cryonic preservation allows living cells to be stored at very low temperatures. Cryonics is not legally allowed to be carried on living people. People may ask, does it work? It is not possible yet, but it very well could in the future once doctors have developed certain techniques. There are only 3 facilities in the world where you can be cryogenically preserved, two in the US and one in Russia. Although this may seem like a good idea, it does come at a price, it can range from 28,000 to 35,000 (not including transportation). To cover this cost, many people use life insurance. Some people that would like to have this procedure done are, Britney Spears and Larry King. In my opinion, I find it very hard to believe that this could actually work, and even if it did, I do not feel as though you would be the person you were when you were alive before, so I, at this point, would not have the procedure done.

Cryogenic preservation is the process that living tissue is protected from decaying by being stored at extremely low temperatures. One common question that most people wonder is...how do we even know revival is possible? Research shows that insects, eels, and human embryos have been revived and are living well. To convince me that this concept really works, I would want to see more evidence on living things relatively closer to the human being preserved first. Plus, no mammal has ever been successfully cryopreserved and revived. A question I had was...if a person is already dead, what's the point in freeing them when you wouldn’t be able to revive them? One website mentions that “raising the dead” is done everyday in thousands of hospitals. They said we could raise the clinically dead by the standard practice of CPR. If they can prove this concept is a successful guarantee, I believe it could have possibility of a science breakthrough. But right now, I don’t think it's convincing enough.
ReplyDeleteThat's true, who knows how everything will play out. Right now, there is not enough evidence, but in the future it is hard to say what could happen.
DeleteCryogenic preservation is defined as the process by which any living cells, tissues, organs or entire bodies are protected from decay by storing them at extremely low temperatures. The point is to freeze the body and keep the organs alive long enough to find a cure to whatever caused their death in the first place. Cryogenic preservation isn't proven to work on large organs like a kidney or etc. because we can't sustain them them in the proper environment. However, it does work with living cells such as blood cells. Unfortunately, it costs a considerable amount of money to use cryogenic preservation on someone because of how expensive it is to run the process. I think it may be possible to have a successful example of cryogenic preservation in the near future. I might not go for cryogenic preservation because I wouldn't want to be a tax on my family and drain that much money for a very slim chance at life.
ReplyDeleteCryogenic preservation is when an organelles, cells, or other biological constructs are preserved by cooling and freezing at a very low temperature. A whole body could cost as much as $200,000 and $80,000 for a head only. I think that with the science we have today, and in the future, scientists will be able to freeze an organism's head and place it into another person's body. This process buys scientists time to find out maybe a cure or cause for a disease and potentially research it and use this evidence in the future. I think that this is a good idea and can help with a lot of research later on to save things and pick up at a later time when we know what we’re dealing with and the effects of something that may be unknown at the moment.
ReplyDeleteWow! As cool as this is that is a lot of money to spend just for a very small chance of being revived. I agree that this is a very good idea and definitely help with future research.
DeleteCryonics are the science of using ultra-cold temperature to preserve human life with the intent of restoring good health when technology becomes available to do so. Though this seems like a crazy subject, it is actually theoretically quite possible. Except however, the cost. Keeping a whole body preserved could be up to $200,000 or you could just freeze your head for $28,000! Is doing this really worth it though? Costing your family so much money just to be frozen in case something might happen? I guess that’s up for the person to decide. In my opinion, I think freezing my body would be pretty cool and I would like to donate parts of my body to science or for medical reasons when I die, so maybe I’ll just have to try this! Do you think that spending this much money to be frozen is worth it?
ReplyDeleteI don't personally think that it would be worth it because you don't know if it will work or if its a scam.
DeleteCryopreservation or cryoconservation is a process where organelles, cells, tissues, extracellular matrix, organs or any other biological constructs susceptible to damage caused by unregulated chemical kinetics are preserved by cooling to very low temperatures (typically −80 °C using solid carbon dioxide or −196 °C According to the Cryonics Institute, “Prices with other organizations can be as much as $200,000 or more for whole body cryopreservation and $80,000 for a "neuro" (head-only) option. With CI, a whole body cryopreservation costs as little as $28,000.00, rendering an alternative "neuro" option unnecessary. I really find it fascinating that a child came up with the idea to preserve herself. I would've never thought of that. Sources say that it could happen if the nanotechnology is there and if the circumstances are right. But who knows.
ReplyDeletePersonally this is why I don't think cryogenics is worth it, it is very expensive and the technology isn't all there.
DeleteI personally don't really believe in Cryopreservation, I'm not saying that it doesn't work i just don't really see a point. We all die and I feel like it should stay like that we have all lived our lives, some maybe less and some maybe more than others. Cryopreservation is the process by which any living cells, tissues, organs or entire bodies are protected from decay by storing them at extremely low temperatures. From what I heard there are no mammals that they have brought back to life but there is a thing called the, ‘tardigrade’ animal which they had collected in Antarctica and that has been brought back. I also learned that after the heart stops, and preferably within 15 minutes, Cryonics procedures should begin.
ReplyDeleteCryonics is basically the process of storing an organism at low temperatures to possibly resurrect it in the future. Protecting the brain is important as we lack the technology to properly preserve the whole human body. Scientists seem to struggle with finding a way to freeze the body without damaging cells so animals have been used often. For example, a group of scientists froze and then thawed a rabbit's kidney. They later put the kidney back in the rabbit and it was as good as new. However, we still have a long way to go since the brain is more complex than a rabbit's kidney. Most scientists are trying to mimic animals that can survive after freezing like frogs and Nematode worms, but our bodies are too different. Of course cryonics is expensive but the price truly depends on whether you want your body frozen or not. I've seen prices below $25k and above $100k. I believe cryonics is perfectly fine right now but in the future it could lead to many problems. If cryonics becomes a common thing then the world will quickly be overpopulated and Malthus would disapprove strongly.
ReplyDeleteCryonics is the process of freezing people at very low temperatures so that they can be revived in the future. This idea began in 1962, when scientist Robert Ettinger suggested that freezing people could preserve them, so that in the future, advanced medicine could revive them. It is believed that a person is not truly dead, until the mind stops working. If you preserve the mind, you can preserve the body and person, meaning that they can be cured in the future, once the right technology has been developed. Today, we are able to freeze a handful of cells for up to 12 years, before they must be replanted. I don’t have an opinion on cryogenics because I can see and understand both arguments. However, I do believe that if we learn how to successfully, and safely, preserve and bring someone back to life, there could many positive outcomes.
ReplyDeleteCryonics is a method of preserving humans by freezing them. This requires a temperature of -196 degrees Celsius in the liquid nitrogen the bodies are stored in. The idea is that in the future there will be technology to revive and cure these people using tiny nanobots or advanced medicine. At the time this is just a theory, so no one really knows if it will work, yet several people, like Ted Williams, have taken their chances at being revived in the future. While I think it is unlikely that this will work, I think if I had some fatal disease at a young age, I might as well take my chances at being revived in the future and living a long healthy life. Cryonics still has a long way to go before we can even know if it will work, but it is a very interesting concept and considering the huge technological improvements we have made in the last century I could definitely see cryogenically frozen people being revived sometime in the fairly distant future.
ReplyDeleteAfter looking at the Alcor FAQ page which is where Ted Williams had his head frozen I don’t see the point in cryogenics. This is because the technology to reverse it doesn’t yet exist. All the answers to the questions that the company gave were based on the fact that the technology to revive people didn’t exist, but that they were sure it would in the future. To me this is not worth it because the process costs in the tens of thousands of dollars just to begin the process and more for long term care. You also have to decide very fast whether you want to go through with it because they need to begin the process within 15 minutes after the heart stops. With no guarantee that anyone will be able to wake you up again, it is my opinion that cryogenics is not a worth it investment.
ReplyDeleteI agree with you that this process seems pointless. There are so many unknowns in the process to base any hope for the teen's "preserved" future.
DeleteCryogenic preservation is a process where organelles, cells, tissues, extracellular matrix, organs or any other biological constructs vulnerable to damage are preserved by cooling to very low temperatures, typically -80 to -200 degrees Celsius. At these extremely low temperatures any chemical activity that could possibly damage human tissue is theoretically stopped. How do the temperatures not turn the tissue into ice? An example of this is in Water-bears which are microscopic organisms that can survive freezing by replacing most of their internal water with the sugar trehalose. This type of preservation can run north of $200,000 but don’t worry because they have a special price of $80,000 for just your head. I just don’t understand why someone would want this for their body. Why would you try to change a huge part of nature?
ReplyDeleteI agree, we will be messing with the laws is never a good thing and there is so much things that could go wrong. I also think it is too expensive for something that the science isn't here for yet.
DeleteCryonics is the cooling of dead people in liquid nitrogen so that the process of decaying stops and hopefully will allow people to be revived and cured of diseases once they have found a cure for said disease. Although revival of a human has not yet happened they believe it can because of the success that other organisms, such as insects, vinegar eels, several types of human tissue, and small mammals. The cost is not as ridiculous as one might assume, it is $28,000, but apparently most life insurance policies would cover that cost. Personally, I would not want to be cryonically preserved, I will die when it’s my time, but if other people would like the opportunity then they should do it. It would be cool to wake up decades later and tell people you’re from the past. The concept is so revolutionary and fascinating even so, I have never wanted to live forever, so I will take a hard pass.
ReplyDeleteI agree that the idea of living forever is not something I would want, and so would pass on the process. I wonder how religious people feel about this process?
DeleteThe article I read, “What is cryogenic preservation?” explained that this is a process which living cells, tissues, organs or even whole bodies are protected from decay by being stored at very low temperatures over periods of time, costing patients up to $200,000. The original idea of this process is to preserve these bodies until technology catches up and will be able to revive them. Personally, I cannot comprehend why someone would put all of this money and time into something that has a high chance of failing if the technology never catches up with the process. In the article, Dr. Channa Jayasena (who is a clinical senior lecturer in reproductive endocrinology at Imperial College London) says that it is “currently science fiction to suggest that a person could be brought back to life in the future even considering technological advances.” If even an intellectual who teaches at a prestigious school concludes that this idea is very far-fetched, then it must be a long shot for it to happen. He is showing us that even at the progression rate technology is at now is going to make an idea like this one almost impossible, like “science fiction”.
ReplyDeleteAfter doing a little research on cryogenics I was able to find some very interesting and valuable information. I was super intrigued by the Ted Williams story being such a huge sports fan so that where I went first when looking for information. I found an article that talked about the process of freezing Ted Williams' body. The first step involved placing Williams body into a chamber and embalm him in a glycerin-based solution. This would then be cooled under dry ice until it reaches -40 degrees Fahrenheit. Finally, this will be lowered into a pool of liquid nitrogen until the body reaches -320 degrees Fahrenheit. This is key in the preservation process because at this temperature all movement of cells in the body have stopped. Alco, the cryonics center, required Williams to register and pay ahead of time. The payment cost was $280,000.00. This is a staggeringly high and quite frankly it really surprised me to see how expensive this entire process is.
ReplyDeleteCryogenic preservation is the process that living tissue is protected from decaying by being stored at extremely low temperatures. This idea began in 1962, when scientist Robert Ettinger suggested that freezing people could preserve them, so that in the future, advanced medicine could revive them. It is believed that a person is not truly dead, until the mind stops working. Which i think could be really cool if it actually worked. I haven't heard of this actually working yet but I would love to hear the outcome if this actually works.
ReplyDeleteCryonics is the process of cooling a dead body down to the temperature of liquid nitrogen in the hopes that future technology will be able to revive the person. Although revival isn’t possible yet, there has been promising research involving insects,eels,and human tissue, as well as the advancement of nanobiology and stem cell research.The minimum fee for a full body preservation is $28,000, but other companies can be around $200,000 dollars - a small price to pay for another chance at life. Short on cash? For a lower price, you could take the “neuro” option, where just your head is frozen. I think that this is a lot of time, effort and money to put into something that might never work. We’ve never been able to preserve and revive a mammal yet, and humans are the most complex mammals out there. Even if we could revive humans, they would still be left with the ailment that killed them, whether it’s cancer or old age. In that case, we’d have to find cures for nearly everything that a cryopatient could die from, and reverse aging. That’s a whole lot to figure out, but there’s no telling what technological advancements we’ll make over the next century.
ReplyDeleteCryogenic preservation is the preservation of the body at a low temperature to stop tissue decay after humans decease. We would do this in hopes that maybe in the future we could revive the dead with technology. Now do I agree with this? Absolutely not! We should let nature take it's course and let it do it's thing. When it is time to go it's time to go and we should respect that. To be honest I don't think the brain would even function after it stops working! We will not be able to reverse aging or cure all diseases, but we might be able to fix the damages from the freezing in the future.
ReplyDeleteCryogenic preservation is a process in which any organs, or even entire bodies can be protected from decay by keeping them at extremely low temperatures. It is also done on living tissues. Although a teenager who recently died of cancer was frozen as a way to possibly bring her back to life, success is not very common. One surgeon’s opinion is that corn genetically preserved brains could be brought back to life within three years. Professor Canavero stated "We will try to bring the first of the company's patients back to life, not in 100 years. As soon as the first human head transplant has taken place, i.e. no later than 2018, we will be able to attempt to reawaken the first frozen head,” However, I don’t think cryogenics is good idea. Bringing people back from the dead who were supposed to remain that way will have extreme consequences that could crush the hopes of loved ones of the dead. Cryogenetics may be able to work for smaller tissues and possibly organs, but it is my opinion that we need to learn more about it before we start making half-hearted promises and attempting to being whole people back to life.
ReplyDeleteFreezing for good? Cryonics is the science of using ultra-cold temperatures to preserve human life with the intent of restoring good health when technology becomes available (Alcor). The process involves cooling down the body of a legally-dead person to temperature of liquid nitrogen (-196 degrees C). At such ultra low temperatures, the physical decay of the body is halted. The hope is that in the future, science and medical technology will have advanced so that the ‘cryopreserved’ patient can be warmed up / revived and restored to good health. With a cost of $28,000 and no guarantee of success, cryopreservation is a pricey gamble. A month ago I would have been very skeptical about cryopreservation. However, I’m now a wee bit less skeptical. Emphasis on the wee, but at least willing to ponder the possibilities. A family friend recently suffered a severe traumatic brain injury. One of the medical treatments she underwent was therapeutic induced hypothermia. While not cryonics, the process and intent are very similar. Reduce the body and brain temperature with the hope of minimizing additional brain damage and the ripple effect damage to the rest of the body. It’s only done for a short period of time, usually a couple of days. For my friend, this cooling treatment has been successful. It definitely gave her a second chance on life. Her recovery progress has been slow, but it’s progress. Especially when she wasn’t expected to survive. Freezing for good? I’m starting to buy in to the idea, just a wee bit.
ReplyDeleteI agree. At first I was very skeptical of cryogenics and all that it entails but now I am feeling more open to the idea.
DeleteIt would be very expensive for the family if their under age child was to ask for this, it would be kind of selfish leaving your family in so much dept.
DeleteIs it worth it to be frozen after death? Many people have differing opinions on cryogenics, the process of cooling people who are legally dead to to the temperature of liquid nitrogen with the hope that whatever has caused the to die will be curable in the future so they can reverse the process and bring the person back to life. The cryonics process can not legally be performed on living and breathing people yet. No mammals have been brought to the point of cryogenic temperatures and then brought back to life but dogs and monkeys have had their body temperature brought down to 0 degrees Celsius and then been revived. I believe that the process of cryogenics is not worth it. With no actual proof that a person can be brought back to life and no guarantee that what has caused a person to die will be reversible in the future it would not be worth the cost and effort that you and your grieving family would have to go through.
ReplyDeleteTo answer the first question Cryogenic preservation is the preservation of living cells,tissue, muscles, etc, instead of being frozen are instead supercooled to 77 degrees Kelvin as to prevent chemical kinetics from damaging said cells.
ReplyDeleteCryopreservation is already being done on human embryo’s to preserve them for up to twelve years, and revival, at least for embryo’s is possible. Embryo’s, however, only have a small amount of cells when compared to the tens of trillions of cells a full grown person has, all those cells equals more complication.
In my opinion, with my (probably biased) 21st century mind, I kind of doubt that we will ever achieve perfect cryogenic preservation, it seems like there too many problems to fix, I am writing this however, as a public high school freshmen with only a very basic understanding of cryogenics. I am also writing this from the perspective of the 21’st century and what we know in the present day, however I cannot rule out the possibility of cryogenic preservation becoming reality, and as the past has shown me, many people whose ideas or research was ‘crazy’ or ‘impossible’ turned out right in the end.
Cryogenic preservation is the process by which any living cells, tissues , organs or entire bodies from decay by storing them at an extremely low temperatures. Scientist have actually succeeded reviving a mammal. The revived ‘tardigrade’ an animal which they found in antarctica. They brought this animal back after 30 years of being frozen. To be cryopreserved cost about 200,000 dollars for the whole body and 80,000 for just the head. That is very expensive but I think it could be worth it if they would be able to revive you.
ReplyDeleteIts so cool that they were able to bring the "tardigrade" back to life but I wonder if it retained the same level of motor and cognitive functions it had before death.
DeleteCryogenics is preserving somebodies body in extremely cold temperatures so that in the future it can be brought back to life. The body is brought back to life by extracting the brain and putting it into a fresh body that way you have the same thoughts and you are the same overall person but just have a different body. Though I wonder what would happen if they weren't able to bring them back 30 years later would they just dispose of the body. Cryogenic preservation is done on the organism as soon as possible after death and is used to preserve the body.I however think that this is wrong because we all have our time on earth and we are not the ones to change and meddle with that.
ReplyDeleteStoring people in freezing temperatures to later bring back to life is the science of Cryogenics. It's a heavy debate right now to figure out if it works and if it's worth the money. To get it done it can cost $200,000 or more. It's all theoretical for us to be able to be frozen and come back to life fine, but there has been tests on animals to see if it can work. The only questions left are: Is this worth it? Would it actually work? is this a need or a want? In my opinion I believe that though this is a break through of medical science I don't believe it is necessary and that it's not natural to freeze yourself just so that you can come back later in life to do what? Go back to having petty debates over what's right and what's wrong and wasting so much time. I believe that we need to do what we need to do as soon as possible because if we don't then the world will become more and more messed up.
ReplyDeleteCryonics is the process of cooling someone who was recently deceased in liquid nitrogen so that they could be preserved indefinitely. Revival is too complicated for science at this point, but many who undergo the operation have high hopes to be brought back in the distant future when our science has advanced substantially. There have been successful freezings and revivals of mammals, although not from cryogenic temperatures. An example of this is that monkeys and dogs have had their blood cooled and replaced after revival. Luckily, being frozen is not as expensive as many think. There is a one time of about $28,00 and is due at the time of death, and a monthly payment can be arranged so that money is set aside starting at $30. With all that said I think the entire process is worth it depending on who you are, and by that I mean only people whose quality of life has been degraded by any means. If everyone were to be cryogenically frozen then as a society it would be difficult for us to evolve. Not only physically but mentally we would not advance as our views probably wouldn’t change as much as they should, and all in all cryogenics should only be an option for a select percent of the population.
ReplyDeleteCryogenic preservation is essentially the freezing of either an entire deceased organisms body head or other organs. This is done by cooling the body to -320◦F drain the organism of all its blood and replacing it with cyropresevants to prevent ice crystals from forming in the blood. The idea is that this preserves the organism allowing it to be revived in the future when whatever ailment it died from is cured. I do not believe it will ever be possible to fully cure the disease of a dead person and bring them back to life with full cognitive or even partly cognitive function. The brain is a very fickle thing and even having hypothermia for an extended period of time can to irreversible damage to it I can't imagine what years in subzero temperatures would do to it. They could end up in a vegetative state or with an IQ of 64. While we may be able to cure the diseases that the person dies from the antifreeze that has been sitting in their body will surely have poisoned their organs after a few years and the function would probably be limited at best. Forcing them to live a life of medications and hospital visits. All in all I do not think cryogenic preservation will work and be able to restore life to those who died years ago, at least not one they would like to live.
ReplyDeleteCryogenics is done to living things like worms and rabbits but even though they were able to be revived and still worked like they did before being frozen they are much simpler than humans so it's encouraging that we can bring something back but we still have a little way to go before we bring someone back instead of a rabbit or worm. It may be possible to cure every disease one day if we all worked on it but it take awhile to find the cure for every disease we have to our knowledge. Also reverse aging and fixing damage from freezing would be great but what would we have to do to achieve that. Nano bots seem like a logical choice but we are far off from even forming something so complex at the molecular level. The only way the nanobots would fix damages on the cells would be at a molecular level and since we haven't figured out how to make something that small yet we still have a long way to go before we do everything we dream of accomplishing. Why does it have to be so hard for us to get what we want or need? Wouldn’t it be much easier if the world wasn't so complex and harsh? I think it would be much easier but then none of us would ever learn something new and become better for the sake of humanity. Life is cruel and difficult but eventually we'll figure out a way to do what we want to do.
ReplyDeleteAfter watching the video on cryogenics I realized that we can freeze organs from a dead organism and put them in that of living one, but this was done with a rabbits kidney not an entire human body. From the video it seems like scientist can freeze and keep a body fresh, but this is nothing new we do this with lots of foods everyday.The real problem in cryogenics is figuring out how to unfreeze that body without causing damage to it. I feel like our government needs to stop all research on anything dealing with bringing the dead back or creating new life, because I do feel that this is more fact then fiction. We don't need a bunch of people from the 2000's being brought back in 3005 when everyone s creating perfect babies. I also feel that we would then run into a problem where we have to figure out when to unfreeze these people what if their disease is incurable , there family forgot that there great great great great great ... grandfather is frozen or they can't afford to unfreeze them, what happens then.
