The Australian Experiment
It was a classic purely scientific experiment.
Australian researchers were interested in, of all things, mouse contraceptives.
To this end they modified a mousepox virus to contain the gene
for interleukin-4 (IL-4) as well as the mouse egg shell protein (ZP3). The
egg shell protein was there to encourage a contraceptive response against
the mouse's own eggs. The IL-4 gene was there to increase the immune
response against ZP3 protein, so as to make the contraceptive response
more effective. The mousepox itself was a relatively benign virus, of little
threat to the health of the mice themselves.
The results were, to put it mildly, unexpected. When the genetically
engineered mousepox was put into mice the mice simply
died. The supposedly benign mousepox
virus was discovered to have become a killer. And not only a killer,
but a super-killer: 100% of the mice died.
The scientists
thought they might learn something
useful about mouse contraception, but instead they had learned how to create
a universally fatal virus. And this killer virus had been
created via a very simple genetic manipulation, accessible
to every country with a few PhD microbiologists. Imagine their surprise.
After much debate, the results were published 18 months after the
experiment. And the results were easily replicated and
verified in independent labs. The result was widespread
terror within the defense
and medical community. If this technique could be
used on a mouse virus, why not a human one?
Smallpox and mousepox are very closely related. Would smallpox+IL-4
create a superpox? This is very likely. As one scientist said, "if
some idiot put IL-4 into smallpox, they'd increase the lethality quite
dramatically ... I wouldn't want to be the one to do this experiment."
He won't need to. Others have volunteered;
no doubt this question is being answered right now in clandestine
labs around the globe. The technology is easily accessible, the technique is
published. All it takes now is intent and a modest lab.
And, if this particular technique doesn't work, perhaps another
one will do the trick ...
This mousepox experiment is hardly unique. Other
techniques are being pioneered and other biological products are
being produced, which are at least as troubling. For example,
a number of firms are working on modifying the common
cold virus so that it can combat cancer. These modifications take
a variety of forms. In some the virus is modified so that
it can only attach to cells that have a deficient defense of
some sort, of a a type seen only in cancer cells. One such
defense is the p53 gene, which is preferentially inactive in
certain cancerous cells. Another such
defense, called the retinoblastoma tumor suppressor protein (pRB)
pathway, is known to be defective in nearly all human cancers.
Once a targetable difference is determined, the virus is
engineered such that it can only attack cells
with that particular defect or expression. Once in
the cancer cell the cold virus is further modified to
increase its lethality. For instance, in some implementations
the cold virus is given
genes that, when expressed in the target cancer cell,
make it more susceptible to anti-cancer drugs.
Another interesting recent medical approach involves
chimeric viruses. These are basically combinations of
multiple organisms, thus ideally presenting the strengths
of both. One such chimera - a combination of the common cold
and polio - has shown great promise in brain cancer (curing it,
not causing it).
In aggregate, these viral therapies appear to be a very
promising avenue in anti-cancer research.
Why is this a problem? Aren't new anti-cancer techiques a
good thing? No doubt about it. However, the problem is not
in these particular implementations, but the overall technology
itself. For example, applying these same
techniques, why couldn't the common cold virus be
engineered to more effectively attack non cancerous cells?
The common cold virus is exactly that - common. If it could be
made generally lethal as well, then it would make for an
absolutely devastating weapon. Why not a chimera of the
common cold and HIV?
One might argue that mankind would never develop such a virus,
given it would be in no one's interest. Well, World War 1 was in no
one's interest too, and yet it happened anyway.
The historical
record is not particularly comforting on this point.
All these experiments and products clearly illustrate
the paradox we face: basic scientific research, one of mankind's
purest and most noble endeavors, increasingly
reveals the seeds of our own destruction.
