Life
as a popsicle
By Kevin Miller
OTTAWA — It’s
the stuff of science fiction and pseudo-scientific web
sites. The idea of freezing people and then thawing
them out decades, if not centuries, later sounds like
something out of an episode of Star Trek.
But is there anything to the extraordinary
idea that, in years to come, we can be revived to become
productive members of a future society?
According to Cryobiologist Kenneth Storey,
when discussing cryonics, the line between religion
and science becomes blurred and rational thought processes
sometimes go out the window.
Storey likens it to the fight between
the church and science over creationism. “The
same battle was drawn when Darwin published his book
on the origin of the species where he showed that evolution
was true, and there was a lot of evidence for it.”
In that case, the church claimed to have
the answers to how man came to be on Earth, and science
proved them wrong. In this case, as Storey says, “they
are more or less a theology; there is really no difference
between cryonics and any other religious organization.
They have the truth with no proof, you must have faith
but you can never see a real example of it, you must
do what they say without any hesitation (give large
amounts of money to them every so often) and they have
the key to eternal life.”
It’s not just the faith-based aspects
of cryonics that Storey takes issue with. One of his
problems with cryonics is that he says it’s based
on a flawed key principle, a process called vitrification.
According to the Alcor Life Extension
Facility, the largest cryonics company in the world,
“the (vitrification) procedure involves partly
replacing water in cells with a mixture of chemicals
that prevent ice formation. This is a method of stabilizing
the physical basis of the human mind for practically
unlimited periods of time.”

Dr. Kenneth Storey disagrees
with claims that people will one day be able to
revive frozen bodies. |
Storey agrees that theoretically, vitrification
will hold the cells as if frozen in time. In this process,
the temperature of the water (or mixture of chemicals,
as in Alcors procedures) is reduced so fast that ice
doesn’t have time to form. Storey says the cells
must cool “at 1,000 degrees a minute,” or
as he describes it somewhat less scientifically, “really,
really, really fast.” The rapid temperature reduction
causes the water to become a glass, rather than ice.
It’s a bit complicated, but there
are easier ways to picture it. Imagine people on a street
as water molecules. When the water is free flowing,
the people are moving with ease. If time were to stop
instantly, everyone would suddenly stop moving in exactly
the place they were. However, if time were to slow down
gradually, people would have time to gather and talk
about what was happening. The same is true of water
molecules in vitrification, the molecules have their
temperature reduced so fast that they don’t have
time to gather and form ice, and since ice is what damages
cells in the first place, they will remain frozen in
time permanently.
Alcor’s vitrification claim, according
to Storey, is in fact, accurate, “Absolutely true,
there’s no question, if you want to be frozen…and
come back as one brain cell, well, it’s your money.
But the thing is it works for one cell, and it looks
marvelous, but it doesn’t work for the whole brain.”
The freezing process is a valid scientific
principle, and in fact, Storey regularly vitrifies individual
cells, and small groups of cells in his lab at Carleton
University in Ottawa. The thawing process, however,
is entirely speculative and is based on unknown, and
yet-to-be invented technology.
Storey says the problem is that Alcor’s
procedures don’t talk about the thawing process.
Storey does. He says there will be this "horrible
reckoning" at those sort of warming temperatures
that naturally occur, when water will go from a vitrified,
or glass state, and turn into ice — destroying
the cells.
Storey has two main problems with Alcor
and other cryonics organizations. First, he says they
only focus on the freezing, and don’t talk about
the problems that will occur in thawing the bodies.
Secondly, they put far too much faith in vitrification
as a saviour. “Vitrification, although an interesting
phenomenon in the lab, is simply not going to transfer
itself to organs in the real world. It will never work
for organs, and it will certainly never work for human
bodies.”
So, in the face of all the evidence that
this won’t work, how do cryonics supporters defend
their ideas?
George Dworsky is the president of the
Toronto Transhumanist Association, a group devoted to
“improving the human condition through the use
of…available technologies to eliminate aging.”
Transhumanists are typical of cryonics
supporters. The general idea behind their beliefs is
that if you told someone a century ago that men would
walk on the moon and talk to each other on wireless
phones while driving 120 kilometres per hour on an eight-lane
highway, you would have been ridiculed in the same way
they believe they are being treated.
Dworsky admits that there isn’t
any real evidence right now. “I can’t sit
here today and look you in the eye and tell you we are
going to bring people back. Anyone who is going to tell
you that is either deluding themselves, or they’re
not being realistic... I think there are enough clues
now to give us some hope.”
He also admits that the thawing process
will need “a radically futuristic technology (that)
could resuscitate or revitalize the person.”
Cryonics supporters like Dworsky and Alcor,
put their faith in sciences ability to create things
that are inconceivable at this time. Yet the lack of
real science, and the propensity toward speculation
in cryonics is what has caused it to develop the quasi-religious
fervour that Storey has seen among its followers.
Storey prefers to deal with science that
is applicable today. He is currently studying the way
mammals hibernate, in order to prolong the shelf life
of organs being used for transplants. “We don’t
want to have to take a heart and realize it’ll
only live for four hours and have to run it through
an airport in a picnic basket full of ice.”
He prefers to deal with this kind of research
because he can see the results it is having on the world.
“I’ve published nearly 500 papers, I have
an endowed chair in research science, I’m world-known
in the field of cryobiology and I think I’m actually
doing something useful.”
Already, the results from this type of
research are being felt. “Figuring out how to
lengthen the time of transplantable organs happens,
literally, on a month by month basis…the survival
times of organs has grown from one hour to four hours,
four hours to eight hours, in terms of kidneys, maybe
eight hours to 18 hours, but the growth is incremental.
Science, at this stage does not work by some huge breakthrough.”
Storey does concede that cryonics, defined
as the freezing and reviving of an animal can happen,
but is quick to strike down the idea of human cryonics,
saying “tragically for cryonics, those animals
are only frogs and turtles.” Frogs and turtles
survive the winter by allowing themselves to freeze
solid and thaw in the spring.
Storey’s distaste for cryonics isn’t
limited to the fact that they have no real science,
in the end, he says, the fundamental problem with cryonics
is that “they (claim) they will somehow overturn
the laws of physics, and chemistry and evolution and
molecular science because they have the way. There is
no difference between somebody dressing up in a long
robe, and being the son of some deity or other that’s
going to take you to a planet far away if you buy some
new Nike sneakers, and cryonics which promises you,
in the face of overwhelming evidence, that they will
overcome, literally, objective reality…it’s
not science, it’s a religion, we can’t really
fight it on the basis of science because they don’t
have any.”
At this time, cryonics is impossible,
even the supporters admit that. And experts like Storey
say it will never be possible. But who really knows,
maybe future generations will be watching a freshly
thawed Ted Williams back in left field for the Boston
Red Sox? Williams’ body was preserved by his son
and Alcor following the baseball legend's death in 2002.
As Storey sums it up: “In a hundred
years or so, we’ll know which approach was valuable.
The advantage there is that if they were right, they’ll
all be alive and thawed out, and I’ll be well
and truly dead, so I won’t care then either."
