Hi RAMole,
thanks :-)
Here is the direct comparison of "Google-Translation" and "Babel Fish".

An elegant method for the preservation of proteins, American researchers
have developed. By tiny drops of a protein solution into a liquid desiccant
type, transforming the droplets into beads of glass protein.

"This protein is non-crystalline glass," said David Needham of Duke
University, "it is rather a frozen liquid." Unlike in a crystal, the
molecules are not arranged in a glass lined up in formation. Apparently, the
dehydration successes so fast that the relatively large protein molecules
can not slip into a crystal lattice.
In their experiments, Needham and colleagues appeared a thin pipette tip in
decanol, a relative of the long-chain alcohol drinking ethanol. Then they
pressed a tiny drop of protein solution from the tip. Within a short time
that went into the protein solution contained in the alcohol over water.
Leaving behind a few hundredths of a millimeter large pearl pure protein,
the researchers report in the "Biophysical Journal.
The process works so carefully that in glass convicted enzymes after
re-addition of water are again operational, initial tests showed four
different proteins. The reason for this is likely to pass only the water
molecules in the vicinity of the proteins in the alcohol. Those water
molecules that are embedded in the structure of large protein molecules,
however, remain in place.
For microbes is not this "structural water" accessible, so that the protein
glass does not constitute a breeding ground for bacteria or fungi, said
Needham colleague David Gaul. In addition, protein glass is easier to
produce and easier to use as a freeze-injected protein and could, for
example in the case of therapeutic proteins directly into the body. A patent
for their technique, the researchers have applied already.

American researchers developed an elegant method for the preservation of
proteins. By giving tiny drops to a protein solution to a liquid desiccator,
the droplets transform into beads from protein glass. Picture: Deborah
Rickard, Pratt School OF engineering, Duke University "This protein glass is
not crystalline", explains David Needham of the Duke University, "it is
rather a rigid liquid." Differently than in a crystal, the molecules are in
a glass not in line up and member arranged. Obviously take place the
dehydration so rapidly that the comparatively large protein molecules no
more could not slip into a crystal lattice. With their experiments Needham
and colleagues dipped a thin pipette point into Dekanol, langkettigen
relatives of the drinking alcohol ethanol. Then they pressed a tiny drop of
a protein solution from the point. Within short time the water contained in
the protein solution changed into the alcohol. Back few Hunderstel
millimeter remained a large bead of pure protein, reports the researchers in
the "Biophysical journal". The procedure works so carefully that in glass
transferred enzymes are again functional after renewed addition of water,
resulted in first tests with four different proteins. The reason for the
fact might be that only the water molecules change into the environment of
the proteins into the alcohol. Those water molecules, which are embedded
into the structure of the large protein molecules, remain against it at
their place. For microbes this "structural water" is not accessible, so that
the protein glass does not represent fertile soil for bacteria or mushrooms,
describes Needhams colleague David Gaul. Besides protein glass is easier to
manufacture and more simply manageable than freezingdried protein and can,
approximately in case of therapeutic proteins, directly into the body be
injected. The researchers already requested a patent on their technology.

Hello all:
Here is an on-line translation of the paper pasted here in German. The
translation is pretty good in spots and otherwise it's amusing. It gives a
good idea of the current state of translation programs (and would probably
do
much better on non-technical material.) The original text is below so those
who read German better than I can make comparisons.

Subject: New Technique Turns Proteins Into Glass
****************************
Information in German:
Zitat: " Protein zu Glasperlen 19. Marz 2010 12:17
Eine elegante Methode zur Konservierung von EiweiBen haben amerikanische
Forscher entwickelt. Indem sie winzige Tropfen einer Proteinlosung in ein
flussiges Trockenmittel geben, verwandeln sich die Tropfchen in Perlen aus
Proteinglas.
"Dieses Proteinglas ist nicht kristallin", erklart David Needham von der
Duke University, "es ist vielmehr eine erstarrte Flussigkeit." Anders als
in
einem Kristall, seien die Molekule in einem Glas nicht in Reih und Glied
angeordnet. Offenbar erfolge der Wasserentzug so rasch, dass die
vergleichsweise groBen Proteinmolekule nicht mehr in ein Kristallgitter
rutschen konnten.
Bei ihren Experimenten tauchten Needham und Kollegen eine dunne
Pipettenspitze in Dekanol, einen langkettigen Verwandten des Trinkalkohols
Ethanol. Dann druckten sie einen winzigen Tropfen einer Proteinlosung aus
der Spitze. Binnen kurzer Zeit ging das in der Proteinlosung enthaltene
Wasser in den Alkohol uber. Zuruck blieb eine wenige Hunderstel Millimeter
groBe Perle reinen Proteins, berichten die Forscher im "Biophysical
Journal".
Das Verfahren arbeitet so schonend, dass in Glas uberfuhrte Enzyme nach
erneuter Zugabe von Wasser wieder funktionstuchtig sind, ergaben erste
Tests
mit vier verschiedenen Proteinen. Der Grund dafur durfte sein, dass nur die
Wassermolekule in der Umgebung der Proteine in den Alkohol ubergehen. Jene
Wassermolekule, die in die Struktur der groBen Proteinmolekule eingebettet
sind, bleiben dagegen an ihrem Platz.
Fur Mikroben sei dieses "Strukturwasser" nicht zuganglich, sodass das
Proteinglas keinen Nahrboden fur Bakterien oder Pilze darstelle, erlautert
Needhams Kollege David Gaul. Zudem sei Proteinglas leichter herzustellen
und
einfacher handhabbar als gefriergetrocknetes Protein und konne, etwa im
Falle therapeutischer EiweiBe, direkt in den Korper injiziert werden. Ein
Patent auf ihre Technik haben die Forscher bereits beantragt.

Dear friends, true words block a clouded vision. When it's funny, don't rate this message as poor. The telegraph.co.uk article from 17 Mar 2010 is called: medieval child's brain to unlock human thought processes. See, there we got it! They had witch potions 800 years ago, that's probably the magic brew where bacteria made the enzymes reacting with body fats, water, and hydrogen, producing a soap-like substance to preserve some neurons and other tiny things in that brain.
They also had powerful wizards 800 years ago in Quimper, Brittany, not far from the location where the grave was excavated 1998. So Christina Papageorgopoulou might have written the Neuroimage article under the influence of an evil spell from Gaulish druids and the 18 years old boy was probably a bewitched prince, trying to break the unblemished sciences with spiritual forces in a single (and therefore paranormal) brain preservation that occurred despite the absence of cryogenic temperatures. But beware, there's an 8 in the above 3 numbers.
Frank Ruhli, head of the Swiss Mummy Project at the University of Zurich, has already hosted holy majesties like the great Egyptian King Tutankhamun who are likely now to seek revenge for their plundered graves. See, there's a secret omen too! So stay away from an alchemy like this, nothing good will come over us when the curse of the mummy's tomb strikes the outlawed.

Subject: Down with Uploading
Content-Language: en
The relevance of this to cryonics is marginal but not zero. It is
political or PR-related.
I think there is a small but not insignificant group who think that, since
quite a few
cryonicists are also Uploaders, they are tarred with the same brush.
This was instigated by my recent second looks at some works by uploaders,
including
Perry, Tipler, Moravec, and Kurzweil.
Curiously, I have a lot of respect for the first two, but not much"in this
context"for
the latter two. Mike Perry, in particular, I believe thoroughly
understands my arguments
against the uploading thesis. He isn't dogmatic, admits he might be wrong,
and has
many splendid things to say, such as early in Forever for All that what we
should aim
for in life is a preponderance of satisfaction over dissatisfaction"the
meat of my
book Youniverse. Cosmologist FrankTipler makes bolder and more dogmatic
statements,
in The Physics of Immortality, some of which I consider clearly wrong,
but still offers
good food for thought. Moravec and Kurzweil, on the other hand, I think
make too
many obvious blunders and are basically lightweights in this area.
So let me attempt in extreme brevity first to list some of the
shortcomings of the
Uploading thesis. If there is any interest, I could follow this with more
detail.
It's all old hat, of course, but there are always new people and old
people with
new interests. These notes are in no particular order.
"Identity of indiscernibles" is a common tenet. Often attributed to
Leibniz,
one version is that if two physical objects or systems cannot be
distinguished
from each other by any criterion, then they must be considered the "same"
or identical.
First, this assertion actually asserts nothing except a certain preference
in
use of language. It has no consequences. It is also useless because if
the
question arises, are A and B distinguishable, the answer is always yes. An
example might be two hydrogen atoms, which some would say fill the
bill. But the atoms at minimum are at different locations, hence are
distinguishable, e.g. by a mass detector of appropriate sensitivity. In
addition, being at different locations, they necessarily differ in other
ways too, such as the gravitational fields to which they are subjected.
The sufficiency of isomorphism is a pervasive and clearly wrong
idea. Isomorphism means roughly same-in-form, and refers most
commonly to the fact that, in a computer simulation of a physical
object or system, every attribute of the original has a counterpart
in the simulation, and it is therefore allowable to think that the
simulation is "just as good" as the original and that a simulated
person would be alive and conscious.
Among other fatal afflictions, which I have spelled out in Youniverse,
this idea simply assumes, without proof, that a description or
representation of a thing is the "same" as the thing. In a few limited
circumstances this is true, the most obvious example being a map.
If two maps show the same city with equal fidelity, the maps are
essentially the same and either can be used. But no map is the city.
The map is not the territory, and a description of a person, no matter
how detailed and whether or not dynamic, is not the person.
For an easily understood reductio ad absurdum, consider a
description of a hydrogen atom, in its ground state and far
removed from all other influences. Anyone"even I"could
write down, with pencil and paper, words and numbers
providing a quantum mechanical description of the atom,
its wave equation or equivalent. But no one will claim, I
hope, that the pencil marks on paper CONSTITUTE a hydrogen
atom. Yet this is exactly, in effect, what the Uploaders do
claim. There is no difference, in principle, between a computer
simulation of a hydrogen atom and my pencil marks on
paper. In either case we just have a coded description of
a physical system, which has to be interpreted.
Enough for now. If there are any gluttons for punishment, I
can continue.

Subject: An incentive to manage reanimation trusts.
From: MARK PLUS <[email protected]>
The Anticult on Rick Ross's Cult Education Forum seems stuck on the
idea that the people nominated as trustees of a cryonicist's
reanimation fund would immediately steal the money after the
cryonicist dies.
Dr. Steve Harris counters that this almost never happens to all kinds
of posthumous trusts in the real world.
So why would that happen to reanimation trusts? Trustees of fortunes
which don't belong to them gain status by showing that they don't
abuse their positions. An honest trustee signals to other people that
he has integrity and good character, even if the trust he manages and
protects has some unusual but defensible purpose.
