This past weekend, I was in New York City for a meeting organized by Alcor New York, a cryonics community group that is presently seeking to set up a more robust Biostasis Society of New York complete with well-organized standby capacity to help people achieve a successful cryopreservation at the end of life. Setting aside technical issues, the greatest challenge in cryopreservation is the fact the euthanasia, and thus the ability to arrange time of death, remains largely illegal. Hence there must be expensive standby operations, suboptimal deaths that cause significant damage to the brain, and a scramble to ensure rapid cooldown and preservation when death does occur. Since there are only two reputable cryonics providers in the US, local organizations capable of coordinating standby and transport are essential.

A number of folk in the cryonics community can be found in and around New York of late; Aschwin de Wolf and Chana Phaedra of Advanced Neural Biosciences, for example. In the introduction to the meeting, it was noted that early cryonics of the 60s and 70s started as much in New York as in California – there was a Cryonics Society of New York, and restoring that entity seems a worthy goal. There were a few noteworthy visitors from elsewhere, such as one of the Nectome folk, and a representative of the European Biostasis Foundation in Switzerland – this is not CryoSuisse, interestingly enough, but a distinct initiative with some overlapping members.

The talks at the meeting were divided between discussions of progress towards slowing aging or attaining rejuvenation, and discussions of cryonics itself. In general, cryonicists have a strong interest in not dying if all possible, and thus most are quite interested in what is going on in the newly formed longevity industry. The weight given to cryonics is tempered by expectations as to how soon rejuvenation therapies will arrive, and how effective they will be over time.

Joao de Magelhaes presented remotely from the UK, and gave his view on where things stand in working towards therapies to treat aging and thereby slow or reverse age-related degeneration and mortality. He is fairly conservative and pessimistic; he doesn’t think that there will be enough progress in our lifetimes to achieve actuarial escape velocity, but he does think that we will see a slowing of aging in our later lives. Therefore cryonics is very important, and it is particularly important to achieve for cryonics the same that has already been achieved for work on the treatment of aging – to move it from a small, comparatively poorly regarded fringe concern to a field with notable technical successes and greater financial support. In this, there is little substitute for the hard work of bootstrapping, advocacy, research in resource constrained environment, and so forth. On the cryonics side of the house, de Magelhaes is involved in setting up the UK Cryonics and Cryopreservation Research Network to spur more academic research into relevant technologies.

Ben Best spoke about NAD+ upregulation and senolytics; he works at the Life Extension Foundation, and the principals there have recently started to heavily promote these approaches to treating aging. To the extent that they work, this is an example of what will happen to the “anti-aging” industry of fraud and hope and supplements that do little good: many of the people involved are motivated to do something about aging, and thus the good should chase out the bad, given time and therapies that actually work. Ben Best has experimented with these approaches to therapy, as one of the physicians connected with the LEF is willing to prescribe the senolytic dasatinib and NAD+ infusions, but committed the cardinal sin of not assessing metrics before and after. This is sadly prevalent in the self-experimentation community. If you don’t measure, nothing happened. Still, there is evidence for both NAD+ upregulation and senolytics to be beneficial in older people, and sooner or later ever more physicians will become comfortable enough with the evidene to prescribe these therapies the many who might benefit.

Mike Perry gave a fascinating talk on the early history of cryonics, starting in the mid-1960s. It is eye-opening just how much information can be lost even at a distance of a mere fifty to sixty years. For example, James Bedford was the second preserved individual; the first may have been a woman called Sarah Gilbert, but this is uncertain. Of the fifteen people cryopreserved from 1966 to 1973, only Bedford remains. All of the others were lost to the haphazard, unprofessional nature of the early initiatives. Perry exhibited a short film made in 1968 by members of the New York Cryonics Society, showing the process of cryopreservation in one of the dewars of the time. It is quite the artifact of its era.

Chana Phaedra gave a presentation on paths towards optimization of cryopreservation. The success of cryopreservation depends upon delivery of cryoprotectant to the brain, efficiently and rapidly. At present, even in the best of circumstances the perfusion of cryoprotectant isn’t optimal. This is challenging on a number of fronts: the skull is in the way; you can’t just push fluid through tissue at high pressures; the blood-brain barrier blocks all cryoprotectants to some degree. The present conclusion based on work at Advanced Neural Biosciences is that the low-hanging fruit here is finding ways to bypass or open the blood-brain barrier. That may mean new cryoprotectants, or some chemical way of disrupting the blood-brain barrier rapidly and selectively. Other options to improve the situation: faster perfusion, less ischemia, and better assays that can be used in animal studies or on preserved human brains to reliably establish the quality of the preservation.

Aschwin de Wolf discussed the prospects for revival of patients who were frozen rather than vitrified, in part or in whole. The present wisdom is that straight freezing – which can and does occur in sections of the brain given a suboptimal perfusion of cryoprotectant – is highly destructive and causes large amounts of ice crystal formation. Can people with this sort of damage be repaired? De Wolf argued that the best approach, conceptually, is some form of low-temperature repair, via nanomachinery capable of operating in a preserved tissue at liquid nitrogen temperatures. The more interesting part of the discussion was a presentation of straight frozen and then thawed brain tissue that doesn’t appear to have anywhere near as much damage as we might expect. The state of the tissue is worse than the same case for vitrification, but perhaps not as much worse as thought. More work is needed to assess this conjecture, however.

Since one of the presenters was ill, I filled in and gave an impromptu talk on self-experimentation: how to do it responsibly and effectively. We might consider four classes of self-experimentation at increasing levels of sophistication. Class 1: the sort of thing that everyone does with dieting for weight loss or eating foods and supplements for benefits. Class 2: compounds that are easy to obtain, easy to use, have great human safety data, and that may have effects on aging, such as metformin (a poor idea, I think) or senolytics (a better prospect). Class 3: treatments that are logistically challenging, and that may need a personal lab. Few people would be able to safety inject themselves with myostatin antibodies, for example. Get that wrong, and you die. But it is technically plausible, and helpful in terms of spurring muscle growth, given the evidence. Class 4: treatments that require a company or other significant effort to create. Liz Parrish’s efforts with Bioviva , in order to self-experiment with telomerase gene therapy, for example. Or cryonics, for that matter. In near all cases, from dieting to quite sophisticated efforts, people tend self-experiment poorly. They do not do the one fundamental thing, which is to measure the effects.

Researchers in the fields of neurobiology and cryobiology gave a couple of technical presentations. One was an interesting outline of methods that could be used to evaluate the quality of brain preservation protocols, not limited to cryonics. It essentially boils down to examining labelled dendritic spines in neural tissue, which can be done before and after an experimental preservation to see how well the fine structures survived. It is even in principle possible to do this in a brain, rather than just in sections of brain tissue. The second presentation was on the use of computer modelling and machine learning to optimize cryopreservation procedures. There are many variables that can be tweaked, from cooldown trajectory to type and mix of cryoprotectants. Modelling could be used to find optimal parts of this large state space more effectively than other forms of experimentation.

The European Biostasis Foundation (EBF) representative outlined their efforts to build a professional cryonics provider in Switzerland, which would be the first in Europe if they are successful. I liked a lot of what he had to say, particularly that customer focus and scalability are the weak points of the present cryonics industry, given its non-profit roots. Thus one of the initial projects is to ramp up the professionalization of signup and standby. They are launching a brand called Tomorrow, which streamlines the process of signing up for cryopreservation, making it an entirely online process that runs more smoothly and requires less work on the part of the individual. They are also looking into how to make a for-profit cryonics organization viable through the path of long-term asset management, meaning partnership with life insurance companies. As you may know, most cryopreservations are funded by life insurance policies, making it quite cost-effective, particularly if started at a younger age. Middlemen in the the life insurance industry are a well established business model, and so this might be a path towards for-profit cryonics. Beyond these early stage efforts, EBF supports research efforts to improve the quality and reliability of cryopreservation, and is planning a storage facility, but this will be contingent on success in the initial for-profit path, opening the door to capital investment.

Unfortunately I had to leave before the final keynote by Robin Hanson, but it was an interesting event. The cryonics community needs to grow and find success: we live in a strange world, in which there is an alternative to oblivion and the grave, but it is poorly capitalized, poorly supported, and rarely used. Cryonics, as happened for the treatment of aging as a medical condition, must find its way to success and growth. I think that this will be achieved in part by the slow process of building technologies that work, such as reversible vitrification of donor organs, carried out in research communities that presently have little funding for rapid progress, and in part by efforts such as those of the EBF, the process of discovery in business models and persuasion.
