Dig into the field of cryobiology and explore the possibility of humans being frozen and preserved for future resurrection.
--
In 1967, James Bedford had a plan to cheat death. He was the first person to be cryogenically frozen. This process promised to preserve his body until a theoretical future when humanity could cure any illness, and essentially, reverse death. So is it possible to freeze a human, preserve them indefinitely, and then thaw them out? Shannon N. Tessier explores the challenges of human cryopreservation.

While it may be far off for an entire person, this opens the door for a great way to preserve donated organs! Instead of rushing to get permission from grieving relatives due to the viability of their deceased loved one's organs, you could just ask for their organs to get vitrified through an injection or something, to be donated at a later date if at all. Organs could even be harvested and stored for later!

The field of humancryopreservation is lagging behind ... I work in plant cryopreservation and we are able to cryopreserve 1mm³ sized shoot meristem AND plant these plantlets in the field afterwards. Cryopreservation of plant tissue is an important part of gene banking and storing diversity.

@justanotherloki5569 Год назад

Wow, that's really cool. How long were the plantlets preserved for prior to planting and germination? And how many grew afterwards? I'm very curious.

@hanneswilms4632 Год назад

@@justanotherloki5569 it all depends a bit, when developing protocols we store them for at least 30 min, as the material should not change anymore once cooled. I helped develop such a protocol for sweet potato shoots and there we saw some differences between some of our varieties we had 2 where more than 90 % of the material we cryopreserved was able to regenerate into a normal plant and 1 where only 10 % did that. Luckily most of the ones we store have a regeneration rate of more than 50%. These % are species and cultivar dependent. But because we work with clonal material and back ups if some of them die it's not a problem. Other people from my lab are also validating long term storage where they regenerate banana plantlets that have been stored for multiple years. Meanwhile we store hundreds banana accessions which had successfull trials.

@setcheck67 Год назад

Cyberpunk 2077 did a good job explaining why this sucks or SOMA if you are into the less known video games. SOMA is a nightmare of the issues of this. You are not your body, you are not even your brain. The closest thing to actually being you is an electrical loop in your brain. Not THE brain, a loop inside of it. This is important, because when that loop ends by any of many different things, you stop being "You". This has been observed in countless studies, someone was dead a little too long before being resuscitated, part of their brain was removed or damaged, a disease caused atrophy or inflammation in key areas, or even just you aged and certain electrical pathways in your brain opened up or deprecated. Trying to copy that electrical loop, which was created by gradual changes over time to match the circuits created in the brain specifically to accommodate that loop, into a construct, which by design has to have a uniform system of operation is almost bordering on the levels of magical rather than scientific. We're basically talking here that in order for that to be possible, they need to not only have a way to capture the original loop without distorting it, but also create a 1:1 perfect replica of the existing circuit into the circuitry of the machine for every person they do this with. I didn't even go into the higher level stuff how you're not just 1 electrical loop, you're 2 loops that connect to a single completely separate loop while still being their own loops. So they basically need to copy all 3 of your loops AND keep them separated but specifically two of them are able to communicate to the 3rd one or again you become a different person.

@gargidave6285 Год назад

Some thoughts and questions: • Will a person preserved and revived through cryobiology methods have the same qualities, skills, and abilities before his natural death? If physical damage has been done to the body and the mind, by what percentage will they reduce? • If the concept of the 'Atman' is true, what happens to it when the person is in preservation? • Legal consequences: Interim death certificates have to be issued to those who opt for cryogenic preservation which will be scrapped when they're revived. The hospital or the laboratory will contact the family and some government officials to decide if the person should be revived and who will look after him (accommodation, food, etc.); the government may take responsibility for those who don't have family and can contribute to the country's progress. This will help avoid both civil and criminal issues. • Social consequences: Whether or not the person can reproduce after being revived? If yes, will they have normal babies or be physically disabled? • Economic consequences: More competition for jobs.

@slamp3844 Год назад

The last question doesnt make sense. More people wont neccessarily equate to more competition. A greater worker force however is needed to keep up any govnerment. Also, for your first question, no idea. As mentioned in the video, cryobiology cant exactly revive you. But lets say it did, then the amount of damage or changes done to the brain be the biggest factor in what you need to relearn, and it depends entirely on where the damage is, which no one would know.

There's this show I watch called Manifest. It's about a plane that came back 5 1/2 after it took off. In one episode, you learn that some of the passengers had no one waiting for them when they came back which meant they had no where to go after the plane ride. When you think about it, would cryogenically freezing yourself be worth it if there's no one to greet you when you come out? In fact, there a couple of episodes of Batman TAS which addressed the idea of cryogenically freezing someone with a terminal illness until a cure was found. Our technology might be more advanced now than it was back when the show first came on but we're still no closer to finding a cure for cancer than we are to inventing flying cars.

What about harnessing and building on the limitations of natural hibernation to achieve something similar to the stasis sleep of sci-fi movies. It could be useful for things like trips to Mars, where one or two of the crew are awake in 6 month shifts, putting down the previous shift, fine tuning instruments, ensuring the snoozing crew's muscles do not atrophy, other astronaut chores, waking up the next shift. The crew do not age the full 5 years the trip would take thanks to the extremely slowed metabolic rate caused by hibernation. Though before that we'd need to crack the nascent potential of the axolotl in paralell to hibernation to avoid any complications with the human hibernation process if it has any chance of working.

@setcheck67 Год назад

lol in space travel how much time they experience is entirely up to the tech they have driving the ship. Time is relative and the less gravity you experience, the more time passes for you. This is a bad thing, it means you're aging much faster regardless of hibernation stuff. Having literally 0 gravity is the worst situation. If the ship travels at light speed then it's technically worse as this got explained in the book "The Forever War" where just traveling from one planet to another planet fucks up the time for all 3 places to such an extreme that by the time you reach the other planet they have forgotten about you and are probably so much more advanced they will annihilate you effortlessly. In a nutshell, if they have ships like we use now... They will age drastically faster. If they have a ship traveling at light speed... They will drastically slow aging while both planets undergo many, many years of aging. If they travel faster than light... They will go backwards in time. Where they somehow arrive at the destination before they left the previous location. Probably should hope those are only one way trips.

It's not new information that Tessier is sharing with us cryonicists. Our main concern is whether the damage that occurs during cryopreservation can be reversed, and we firmly believe that it can. We're already aware of the risks associated with cryoprotectants and fracturing, so it's not telling us anything new. As for the idea that there are ethical and social implications that cast doubt on the benefits of cryonics, it's a bit strange and contradictory. We believe that access to potentially life-saving healthcare is a universal human right and everyone should have the opportunity to benefit from it.

@EccentricGentelman Год назад

The problem is not just preserving a person or safely unfreezing them but what we can actually do with them when they get out. For a long time I thought that people who were cryogenically frozen, in suspended animation or stasis were essentially in a state of deep sleep. But then I looked into it and it turns out they are all DEAD, stone dead, deceased. Indeed they NEED to be in order to undergo the freezing process. The whole concept of cryogenic preservation depends on idea that it is possible to reanimate a dead body if it's preserved well enough. All these technologies actually do is keep a dead body from degrading. So these frozen people are waiting for a future that not only has a cure for what was killing them but the same technology as Frankenstein. And even then we still face the issue of the machinery breaking down or whether these cryogenic companies will be able to exist long enough keep people on ice.

That doesn't mean you would see and experience the things that the clone is seeing. That's basically what it would be like to upload your mind to something. Scientists literally can't explain, definitively, what consciousness is and how it operates. We're literally swinging in the dark when it comes to preserving our consciousness outside of our bodies.

@onecommunistboi Год назад

I seem to be alone in this, but the idea of a perfect clone replacing me does not sound frightening. If it happened instantenous without me or the clone knowing then what would have changed? Nothing really. One could argue that this truly happens irl too. The atoms of our bodies are constantly replaced by atoms from our environment, get literally replaced by identical clones. We don't notice it, so there's no harm done to anyone.

@miken7629 Месяц назад

Freezing may be simpler than you think, in Iceland there is a frog that is frozen for up to 7 months a year, before freezing the frog boost it's blood sugar over 40 times which stops it's cells from being destroyed while frozen. Sugar is a natural preservative. Freezing may be possible with glucose injections prior to freezing. Should be easy enough to test.

Pretty sure there's a company that does that already- where they preserve just the head severed from the entire body. Somewhat gruesome if you ask me. There's also this thing with mind-uploading that might be a more feasible goal to preserving someone's consciousness.

@ElusiveTy 9 месяцев назад

@@koshka02Uploading is more feasible and absolutely will be a thing. The issue is that that's not the original person. Someone would be dying so their... Other self can continue on and their loved ones will have them, but not actually them (and who knows whether that's really a comfort). All the while, the original will die and not experience any of it.

Sure it is. Every time you seek medical attention you’re trying to push back against death. Every time you breath, eat or drink you’re pushing your life forward against death. Everyone, everything, we consider living is solving the problem of death second by second. Modern medicine is just taking the solving to a way higher level.
