Recently I read that a lot of people want their bodies frozen so that they can be revived in the future to see how it turned out. Do we have the technology to freeze a person or an animal alive today that can be thawed back to life?

I have heard this technology a few years ago, but my memory failed me. I couldn't remember the source, but the technology had been developed and a few scientists and some cancer patients demanded to be frosen until a day which they can be treated. (Since this is what I've heard long time ago, the source could be false)

Just out of curiosity, when we freeze our body, do we also freeze our mind, i.e. our concious? What if we don't, wouldn't it be a suffering to live under that condition?:confused:

technology since once our body freezes ice crystals tear everything like small knifes.
altough scientists managed to freeze (a fly,a toad,a worm a fish ,i don't really remember what since i saw it on a science show)
it turns out that it has a certain enzime in its body that acts like an anti freeze fluid.(yhe i think i remember now it was a toad but not sure).

I have confirmed my source, it was from a discussion made by my English teacher during an English lesson. I wonder the accuracy of his source...

Is there a way to only crystalise the outer layer of our skin and keep our bofy hydrated, but just keep our body at a low temperature that matabolism virtally stops? Thus we can create a state where we age slowly?

Bacterias thrive even in minus 4 degree celsius. So keeping body at 1 degree C wont do. The solution is some type of antifreeze that permeats all the cells and protects it at say minus 50 C. OR remove the water from the body and replace it with a polymer which is difficult to do.

This seems to me to be really hard to achieve. Just say, there's this tech. already to protect our cells, does this mean the slowing of motabolism, if not, doesn't this seem to be pointless, as we will age and die just like before?

kmguru
08-14-01, 01:21 PM
I think, the metabolish slows down and stops at or below certain temperature. I was watching the demolition man directors narration. They took some of the facts and made a fiction out of it. This was one of those issues.

I have watched the movie and some other films that freezes human after their death in hoping to bring them back to life when technology allows them. This could well happen in the future.

Now this goes back a couple years and all the details have slipped from my mind but I distinctly remember a nature program which showed a type of cricket which lived in an environment with wildly fluctuating temperature changes. During the day it was reasonably warm but at night the temp. dropped to freezing or below and this cricket would hunker down in its tunnel and wait out the night. They had a camera in the tunnel which showed the cricket literally freezing solid, ice crystals formed etc. and then when the sun came up it thawed out and went about it's crickety business.
I figure if we can study how it does this maybe revivification isn't that far off.

P.S. For a good fictional story about Cryology (and the social ramifications) check out The Last Immortal. (I forget the auth.)

I happened to see a grasshopper frozen a few years ago in winter. But I still think that motabolism won't stop completely, but only slows down to a state where we cannot detect easily without precise intruments. Therefore, we will still age, but only slower.

A new life in the physical realm . That is, if the soul finds it necessary. Now, the memory of the previous existense is not lost. It just takes a little effort to wake it up. And then you also have the priviledge to experience the future as a child too, which you can´t if you freeze yourself as an adult.

08-20-01, 12:17 PM
and here we were having a nice discussion about freezing each other. Anyhow let's just stick to the physical realm, in our "present incarnations" and extending the potential overall time in the Universe. If I remember correctly the main problem is freezer burn, when the h2o in the body cools it expands which bursts the cell walls or something like that.
Even if we solve thee purely physical, ignore the purely spiritual, we still have yet to state with any certainty the final composition of the mental faculties.
Can the human conciousness survive being frozen? Will the neurons actually be able to be resuscitated in the future? What do you think?


[Beb's] Your reincarnation huballo don't hold water in our discussion. If we never venture into Cryonics then human stasis will never be a factor of consideration for interstellar flight and we'll never get off this silly little rock.

More on Freezing

An antifreeze protein produced by Antarctic fish has been synthesised in a more robust form by US researchers. The breakthrough will allow much larger amounts of the proteins to be produced for uses as diverse as storing human tissue, making concrete frost resistant, and preventing frozen food going mushy.

The class of proteins - known as antifreeze glycoproteins (AFGPs) - have been widely studied. Without them, ice crystals would form in the fishes' blood and tissues, rupturing the delicate membranes and internal structures of cells. However these fish, cod and notothenioids, have been the only source of AFGPs until now.

"Supply is a major problem," says Ann Oliver, an AFGP researcher at University of California, Davis, "because obtaining the protein from fish is an extremely expensive process."

The new work, by Robert Ben and his colleagues at the State University of New York, Binghamton, should change that. The new technique, "allows the routine production of more chemically and biologically stable AFGP analogues in fairly sizeable quantities," says Ben.

So how would one go about introducing a foriegn protien into a human subject with constructive results. The effect is going to have to be 90% inclusive on a cellular (or is it molecular) level. And do these substances (AFGP's and synth AF) maintain the neural environ at such °'s?

as i recall (having seen that same grasshopper show), the grasshopper's blood actually had a natural antifreeze in it...and thats what allowed it to be frozen....and then thawed......without bursting all of its cells.

08-22-01, 02:27 PM
Hang on, is it viable to use something to stop the blood from freezing? Just thinking about that, it seems to me that the blood would pool in the lowest areas. The heart stops pumping, but the blood isn't frozen only turned into a semi-solid state, there would still be some motion. Over the years there would be rigor mortis.
Blood pooling in tne muscles.
I wonder what technology Zip-lock has with the anti-freezer burn storage bags?

Yes freezing humans without damage is now possible.

Most cryogenic systems now in place do use a system that results in the formation of small ice crystals in the cells. These aren’t too serious except in the brain, where the damage can be quite devastating. So it is currently very unclear what will happen to those who have already been cryogenically frozen using these older techniques, when they are eventually revived.

One hope is that future technology will be sufficiently advanced that it will be able to repair, or supplant the cell damage.

However, in the last year Allcor, the current world leader in cryogenics has developed a new technique known as vitrification. The preparation techniques are important but the freezing process is extremely rapid. The high speed is so fast that ice crystals do not have time to form. The result is a kind of solid frozen form that more resembles those ancient insects captured in amber. The process has been tested on frogs and they have been successfully unfrozen and returned to life.

This process is now the official technique being adopted by Alcor for all new cryogenic clients. However there aren’t too many cryogenic establishments in the world. The best is probably in Arizona, and there is one a few miles from me here in Cupertino CA, and there are several in Europe. However, my local doesn’t do vitrification yet so I will be looking to move to Arizona in the near future.

The key to successful cryogenics is to be treated within 30 minutes of brain death, after that, brain damage is increasingly likely. Since I am only interested in having my brain uploaded then I would only have my brain vitrified. The cost is currently around $15000, and there are other costs associated with future revival.

The vitrification method and its very solid result is ideally suitable to the slicing process that is probably the most likely for brain scanning needed for the uploading process.

And then you also have the priviledge to experience the future as a child too, which you can´t if you freeze yourself as an adult. A lovely fairy story. Of souls and spirits there are many tales and myths, but for now they have no relevance except in the realm of fiction. But fantasies are fun, just be careful not to delude yourself that such things are true, unless you can prove to me otherwise.

One hope is that future technology will be sufficiently advanced that it will be able to repair, or supplant the cell damage.

It may take about 10 years of Proteomics research to have a general idea how to repair the cell structure, another 10 years to do it successfully and so on.

I think freezing a human head now will work this way. Sometime in 2040, non-invasive scanning technology may be available such that, it will upload the neural pattern and memory engram to a computer. It could even be longer like 2100 if our economic condition is going the way it is going now....so right now, it is science-fiction. Sorry Cris...

Freezing wholebody, using AFs may work this way. Once it works, it may be tried on convicted criminals as volunteers with money paid by DOD to save lives in conflict. I will be surprised if this has not already happened. I still think, the repair process will be based on specialized proteins yet to be designed.

Sorry thecurly1, let me add to the topic to discuss what technology derivative we can see in the next few decades that can make Human Freezing and Unfreezing process viable and if successful, do you want to do that for yourself? I mean, do you want to be frozen and setup alarm to wake up in 100 years for a year then go to freeze for another 100 years and so on...
just to find out how the future turned out?

Cris

km,

All I'm really intrested in at this stage is to be sure that my brain can be accurately and perfectly preserved with no damage during the process. I would then hope that science and technology will continue to grow and that safe mechanisms will be available in the future that would allow either my brain to be successfully unfrozen or an invasive scanning process has been proved reliable.

At this time only the preservation process is important.

After the first hundred year wakeup it would be meaningless to stay around society. You are a product of your time and as such there would be very little in common with what existed for society and how you see the world. You would be so alien to them as to have almost no common links. That's putting curisoity on a level I am not sure I would want to take.

Cris
08-29-01, 12:33 AM
Nah, you're just being pessimistic. I sincerely hope that within 100 years we would have developed direct brain input learning techniques. None of this attending schools for 16 years hoping that the information sprayed around might find a target. One month, tops, to reach PhD standards.

I would hope that when I am revived that techniques would be available to update my memories and understanding very rapidly, especially if I am uploaded into a computer based substrate.

Wet1, you are watching too many dumb movies. Most script writers, faced with future projections do not use our accumulated knowledge so far from real science and speculations from Sci-fi movies before us.

If you can not handle going forward only 100 years, what would you do going to heaven where people from 2000 years past are running around talking in gibberish and eating with wooden spoons? Do you think, God sagregates these people by 20 years interval? And if heaven is independent of our time reality (say 90 degrees out of phase) then you may meet future souls too...

If you really put your mind to learn, the neural connections can be newly formed, that is the way we are designed...it is an adaptive organ...

The real problem might well be inflation.

If the money I have deposited or invested that will be used to pay for my revival is inadequate then what motivation will the freezer company have for reviving me? If my money has become so devalued so it is worthless then I hope that they will still revive me and allow me to pay off the debt over time, however, I might not have any useful skills required in the new future time.

Hmm, but I should have an unlimited life- span so I have eternity to pay off my debts.

Another possibility is that money might have been abolished. In which case I have no idea why anyone would want to revive an old fossil like me from te past.

MMMMM! Person-sicles!!!
Perhaps we could whip up some blue/white/pink stripe AFGP's??

But seriously, I think the whole thawing problem could be avoided if the process involved 'flash freezing' instead. Alternatively, let's look at the real problem here: H2O is a uniquely strange molecule, and the only one that exhibits expansion during the cooling process. So, replace the water. It's either that, or the sublimation flash.
In any case, I think the best bet would to just freeze the brain... a la.."The First Immortal', as Hypnogog mentioned.

Last I heard, there were some attempts to freeze flesh very quickly, so as to prevent the formation of ice crystals......(ice crystals destroy cells)........

There was also something about a natural antifreeze which is produced by frogs, fish, ect.......which prevents the formation of ice crystals in their cells during extremely cold conditions. The hope of these determined sci-pros is to produce an extract of this chemical which could be injected/transfused--actually, if I were going to attempt it, I'd use a variant of a dialysis machine to .....:confused: .....nay, that wouldn't work either. The antifreeze chemical would have to be present in every cell, not just the bloodstream.......:confused:.. Anyway, the challenge of circulating an antifreeze agent into every cell within the body would be very difficult. The only possibility that comes to mind would be to perhaps use some form of gene therapy that would presumably cause humans to produce the chemical in each cell.

If the formation ice crystals in living tissue could be averted, then it seems that putting someone into cold storage & then reviving them at a later date might be possible, by many accounts.

Freezing flesh with low temperatures is not the be all/end all of solutions though. The main goal is to simply stop bodily processes, or to <i>suspend the bodies cellular animation.</i> There may well exist a way to temporarily suspend all cellular function without using extremely cold temperatures. Perhaps chemically, or even by some kind of energy field that has a similar effect.

Personally, I'd hate to wake up in the 23rd century, with a bad case of freezer burn ! ! ! !! :D :D :D

Nitrogen encasement and permeation could help. An inert gas that won't allow bacteria to eat flesh.

A big problem with cryotech is the thawing event. It has to be done very quickly or the living tissue begins to decay while the frozen flesh becomes irreversibly nerve damaged. If a person was very thin when on death door, it would help. And make thee hyperventilate with an inert gas just before # is up. Maybe helped along with life support machines until completely saturated with non-oxygen.

Crickets and frogs and lightning bugs reanimate partly because they are so small and thaw quickly.

Nanok,

Good for you. I have to do the same thing shortly as well.

What scheme have you requested? Whole body, head, or just the brain? How close are you to an Alcor center? I understand that if you cannot undergo at least the first stages of freezing within 30 minutes of death then deterioration of your body may be so great that there won’t be much point doing the remaining processes.

The logic for freezing is very simple: If you do nothing then you will cease to exist at some point. If you are frozen then at least you stand a chance no matter how small of future survival.

But I believe Alcor released a statement last year stating that they are adopting the new process that involves extremely rapid freezing, known as vitrification. The effect is very much like the effect that we see of prehistoric mosquitoes that have been perfectly preserved in amber (sap from a tree).

The very rapid process pretty much removes the formation of water crystals that occur during slower freezing and which cause so much cell damage.

The thawing process is clearly the most dangerous stage since ice crystals may well form and cause the damage that should be avoided.

From my perspective I only plan to have my brain vitrified and I hope to go through a future upload process that will likely require that my brain be sliced very finely, while in a solid vitrified form, and the information scanned digitally. Or in other words the issues of thawing will not be applicable.

I look forward to ultimately shedding any vestiges of my biological form.

12-27-01, 01:21 PM
There may be another way.

Two unique features of a human is the DNA and the memory. What if we extract the DNA which is easy to do today and the memory of a person.

Assume that DNA is like the operating system of the brain and the memory is the data (the total experience of the physical world). Combine the two, you get the whole person in a digital form.

What do you think?

Cris
12-27-01, 04:29 PM
Km,

I think the concept is good but the implementation poses some problems.

Human memory doesn’t seem to be conveniently located in a single easily identifiable spot. And things like emotions tend to be both chemical and electrical and again spread among different areas of the brain. All of these features do seem to be intertwined with and within neurons and the synapses.

I suspect that one would still have to perform a brain scan of some sort to extract such memories, and at present such techniques look as though they will be destructive.

But memories are not all that makes each of us unique. It is also the way our neurons have made their connections over time. In effect the way we process memories is unique to each individual. So we need both a copy of the processing algorithms as well as the data (memories+).

Without those unique processing features all uploads would function identically but would just have different memories.

But OK, where would DNA enter into the story? DNA is a static map of our characteristics from birth, it doesn’t reflect how the brain has grown and adapted over a lifetime. I see DNA as a set of guidelines for brain growth but doesn’t actually contain the resultant information.

I suspect an upload only requires a map of actual brain algorithms and memories and has no need for DNA.

But I’m open to more ideas on this. If there was a way to avoid freezing and death then I’m all for it.

Hi Crisp:

Here are my ideas. Ofcourse they are hypothetical and we are talking about stuff that is 30 years away. So, my ideas will be like swiss cheese - lots of holes.

Armed with DNA, you can simulate growth of a person that provides a persons physical abilities, looks etc. If I clone you using your DNA, I will get an exact replica. The only missing part is the memory and adaptive algorithms that you mentioned. To solve that problem, all I have to do is extract your experiences in a time series from birth to whatever time period you set. You do not want to scan your brain after you had Alzheimers or any brain disease that loses your memories. So, you set up a time when your faculties are intact. Now, since we are talking about computer upload, all I have to do is to run the sensory inputs (the time series memory) through your DNA produced empty brain (the baby) and run the simulation at high speed (1000:1) to the time period you specified.

Wallah...you got your brain in a computer....and live in a virtual world happily ever after....

01-03-02, 02:27 PM
Cris, thats great to hear you could possibly get frozen with alcor as well.

And to answer your questions, the scheme will be full body suspension, only because I barely managed to get an insurance plan that would cover it. As for living near an Alcor center, I plan to move very close to a center sometime after I retire.

I have read about the process of vitrification, it sounds like the technology is getting better everyday......hopefully it will become even more rapid.

I also expect my body to eventually become entirely non-living and my memories uploaded into a computer for future existence......thats a scary thought.....

As for right-now, I'm just keeping up with all the latest cryo-freezing info on the internet.

The reason freezing does not work today is because, the cells blow up due to ice crystals. Several fish specis can get frozen and in summer get thawed to go about their business. Their blood has glycol type chemicals that prevent ice crystals. Once we figure out the mechanism, all we have to do is turn on a gene than can pump out such chemicals when the body core gets to 40 F. Then you keep thet body at that temp for 6 hours or so until the blood is saturated with your own antifreeze.

I will not be surprised if the first one will be a human that has an artificial heart pump which starts the process.

Cris
02-10-02, 01:44 AM
km,

The problem of ice crystal formation is solved with the new vitrification process. Essentially freezing takes place so fast that ice crystals do not have time to form.

The issue will be with thawing. However, if uploading is the goal then a vitrified brain would be perfect for the destructive scanner process, e.g. taking very thin slices for very accurate scanning.

[B]err...Cris How about a little Non-destructive process like Gamma ray scanning,or may be MRI for uploading purposes.Nice idea, but current estimates show these technologies are unlikely to achieve the required resolution, at least not in the short term, or if they could then the intensity would be so high that you will fry the target material, i.e. you would still have a destructive result.

Remember with some 100 billion neurons, each with many thousands of dendrites, and then, many more trillions of synapses, and all with wide ranges of electrical variance, plus of course the hormonal and other messenger signals, … and we need perfect accuracy. The technologies you mention are currently thousands of times short of the required accuracy.

Also if you are trying to scan dynamic living tissue then you have the problem of not having a static target. If a cohesive thought is dispersed over many areas of the brain and your scan is not instantaneous then the result may simply be chaotic. Since an instantaneous scan with the required accuracy seems highly unlikely then one answer might be to freeze all brain activity during the scan. And that is something we would want to avoid if the process is meant to be non-destructive.

The best approach for the moment seems to be some form of very high powered electron microscope that can scan at high resolution at extremely small distances from the material and in a 2D framework – i.e. extremely thin bio slices. And where the bioactivity has been suspended.

I have the estimates buried in my email from MURG, I need to dig them out and give you the actual numbers.

From www.lef.org

Whatever the source of cells, tissues and organs for transplantation turn out to be, there is an across-the-board need for improved methods of cryopreservation for storage. Current methods of freezing are quite poor for cells and tissues and completely inadequate for organs. The Life Extension Foundation is funding the development of a technology called vitrification at a private laboratory in Southern California, which allows for long-term cryopreservation of tissues and organs without the formation of damaging ice crystals. The cryobiologists at this laboratory have developed the world’s first synthetic ice-blockers and are close to the successful vitrification of rabbit kidneys. They have also targeted the heart and corneas (for eyes) in their vitrification research.

Well guess wot everyone. Some of you might be aware but a few years ago a dog named "Miles" was put to sleep, put down whatever. It was killed and totally dead. No organs working and absolutly NO BRAIN ACTIVITY. Then Miles was frozen and a year or two later he was warmed up, given blood and now he is 100% normal living dog. Miles' brain is still fully functional even though it died. It has it's own memory fully intact and remembers names and other things from its "Past Life" and the first thing to go wrong in the brain is balance. Miles can balance on his hind legs with ease and has passed every test scientists can throw at him. You could try searching for something like "Miles the dog frozen revived" or something using a search engine. If i find a source on the internet I'll let you's know!

Just a thought.. if you have you're brain scanned at perfect resolution and run in a computer simulation (imagine the pc to do that! ;) ) would it be you ?.. it might be an exact copy, but is still a copy.. in a sense *you* still die when you die, no ?.. am very scheptical about this form of eternal life :rolleyes: if you run the simulation at the same time as you're alive.. who's who hehe. Hopefully when i go in 30 odd years freezing will be proven science, dont see alot of point to life it it just ends.. *sings* "i wanna live for ever" :o

Nothing can live forever and living on in a computer is about as close as we can get (in today imagination). Yes that would be a copy but if the original no longer exist and if the copy believes it is the original then who to tell it different? Remember: “I think there for I am”

HAHAJHhahahaha...right on dental-plan

it never ceases to amaze me how people will concot the weirdest ideas of escape from death. this goes way back. it's all to do with the fear of death.

alright, even RAWlison with his LifeExtension shit knew it was only meant for space travel, nt earth. but jeeez who'd want that. it all sounds to computer room geeky for me....give me spindle branched woods with the clouds moving over head and the possibility of an erotic encounter before i...DIEEEEE!!!! hehe

Cris,

You said that : The process has been tested on frogs and they have been successfully unfrozen and returned to life.

Frog do that each year without any help! That is not a proof!

if with one way or another they manage to freeze brain/body u could trow few bucks in a bank/invest and after 100 years that u wake up u will be a millionaire (even a billionaire depending on the money you invested).
And after that many years technology would be so advanced that u could live forever with uploading or telomerase cause u would be fuckin rich.
I wouldn't use the freeze thingie tho..ONLY if i was about to die from age or a desease.

To freeze a human and keep it alive you'd have to freeze it at a precise rate so as to not damage anything and then keep it at a constant temperature. Near impossible.

I wonder, if you maintain a lower pulse rate, whether you will live longer....??

Only if you assume that a faster metabolism means faster aging.
