And cracks are by far the least serious form of damage because it is the easiest to fix or replace, if you can't fix cracks then you have no hope of fixing the far more serious forms of damage. I don't think any Cryonics patient will be revived until we have Drexler style Nanotechnology and can control matter at the atomic level.</font></div><div class="gmail_quote"><br></div><div class="gmail_quote"><span class="gmail_default" style="font-family:arial,helvetica,sans-serif"></span><font size="4">The key question is if Information Theoretic Death has occurred, if the information on what makes you be you is lost then you're dead. That's why I think Alcor should switch from the vitrification process it uses now to ASC (Aldehyde Stabilized Cryopreservation). In ASC in addition to a cryoprotectant a brain is also infused with the chemical Glutaraldehyde, it's the stuff in wart removing lotion you can get over the counter in any drugstore. Glutaraldehyde kills cells because it crosslinks proteins<span class="gmail_default" style="font-family:arial,helvetica,sans-serif">,</span> but that very cross-linking holds things in place even when they're cooled down to liquid nitrogen temperatures, and so Information Theoretic Death is avoided.</font></div><br><div><font size="4">ASC has been used on a entire pig's brain which was then cooled down to near liquid nitrogen temperatures and then warmed back up to room temperature and sliced into thin sections and sent to a electron microscope. The result was beautiful pictures of synapses and other brain structures that are far superior to the pictures Alcor's current vitrification process can produce, and there is no reason to think molecular-level information wouldn't be preserved too. It's even more impressive when you consider that the pictures were made after rewarming because most of the damage happens at the warming stage not the cooling stage, I would have been delighted even if the pictures were made while the brain was still frozen because I'd be willing to let future technology worry about warming, but this is even better.</font><br><div><br></div><div><div><a href="https://turingchurch.net/cryonics-for-uploaders-the-brain-preservation-prize-has-been-won-cebbe98c241a" target="_blank" rel="noreferrer"><font size="4">Cryonics for uploaders: The Brain Preservation Prize has been won</font></a></div><div><br></div><div><div class="gmail_default"><font face="arial, helvetica, sans-serif"></font><font size="4">Nevertheless Alcor has resisted changing over to ASC, I suspect the reason for their hesitation is that if they did so they would implicitly be saying "<i>we're not even trying to bring that frozen body back to life, we're just trying to preserve the information in it because information on how the atoms are arranged in my brain are different from the way they are arranged in your brain is the only difference between you and me</i>". </font></div><div class="gmail_default"><font size="4"><br></font></div><div class="gmail_default"><font size="4">I happen to think that's exactly what Alcor should be saying, but the ghost of the discredited 19th century theory of Vitalism is still haunting the 21th century and many still think that despite all the scientific evidence to the contrary the atoms in our bodies must somehow have our name scratched on them. I suspect Alcor is reluctant to change because they believe ASC would be bad public relations. But I think reality is more important than PR and the Vitalism superstition could get people killed.</font></div></div><div><div class="gmail_quote"><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><span style="border-collapse:separate"><div dir="ltr"><div dir="ltr"><span style="border-collapse:separate"><div><span class="gmail_default" style="font-family:arial,helvetica,sans-serif">> </span><i>Guided nanotech may be an answer</i></div></span></div></div></span></div></div></div></div></div></div></div></div></div></div></blockquote><div><br></div><div class="gmail_default"><font face="arial, helvetica, sans-serif"></font><font size="4">I don't think there is any "may" about it, without Nanotech there is no hope.
