Genetic Manipulation - The New Weapon Of Mass Destruction
By PNW Staff September 05, 2016 Share this article:
Biological warfare is a frightening possibility that has recently
become more accessible and, potentially, far more powerful due to recent
advances in genetic manipulation called CRISPR.
Early this year, Director of National
Intelligence James Clapper cited genetic manipulation made possible by
the new technique as a threat to national security, adding genetic
manipulation to the list of threats of weapons of mass destruction. But
just what is CRISPER and how much of a threat does this pose?
The
technique's full name is Clustered Regularly Interspaced Short
Palindromic Repeat and it refers to a component of the immune systems of
bacteria that seek to protect themselves against viruses.
The
short and palindromic DNA sequences in bacterial and microorganism
cells precisely cut up and modify virus DNA to protect the cell.
Researchers have now figured out how to harness this process for both
industrial and research purposes.
This is a
classic example of a dual-use technology that has powerfully beneficial
civilian applications as well as devastating military potential. In an
industrial context, the system can be used to create hardier
antibiotics, yogurts and yeasts. The benefit to food production alone
can be substantial.
In research, there is
enormous medical potential in the ability, very precisely, to alter the
DNA of a specific cell or organism. Cures for disease and genetic
disorders are much closer with such a powerful tool for precise genetic
manipulation, but so are engineered bio-weapons.
Bio-weapons
present a unique challenge to nation states. Officially, the
development of biological weapons is prohibited by the Biological and
Toxic Weapons Convention of 1975, signed by 175 countries, including the
US, China and Russia.
But without
continuing research into bio-warfare, a nation is left defenseless
against an enemy that does have continued development. Several secret
programs out of Russia, China and the US have already been discovered,
highlighting the weakness of the treaty itself.
But
what was previously a resource-intensive endeavor only within the reach
of powerful nations, the increased precision and efficiency of the
CRISPR techniques have put far more powerful weapon development
possibilities within reach of any regime or sophisticated criminal
organization.
Biological warfare is not new.
The US Army distributed smallpox infected blankets to American Indian
populations in an act of biological warfare and even the early Mongols
broke sieges by launching diseased bodies over the walls of castles.
During
World War II, the Japanese dropped bubonic plague infected fleas in
ceramic jars onto Chinese cities, releasing plagues that killed untold
thousands.
The US military conducted tests of
bio-weapons on an industrial scale during the Cold War and in September
of 1950, purposely tested bacteria called Serratia marcescens on 800,000 residents of San Francisco, resulting in eleven illnesses and one death, in their attempt to increase its spread.
The research into bacteria such as anthrax and far more deadly viruses was conducted in secret on a massive scale.
But CRISPR allows even greater capabilities to be had in the
garages or low-cost laboratories of any bad actor. Now able to tailor
viruses to specific populations and for very specific effect, it is
theoretically possible to produce pathogens that could render certain
populations sterile or cause genetic mutations in their victims.
As is the case with bio-weapons, they may be easily loosed upon the world but are very difficult to contain or control.
Whereas
the benefits of editing the human genome to remove inherited heart
defects is a great leap forward for science, this technique brings with
it the chance for easily-accessible and precisely-tailored viruses that
are far more difficult to stop.
The double
edged sword of genetic engineering that can produce hardier crops,
improved food supplies and remove genetic defects also threatens to kill
millions with man-made plagues.
Imagine this
system in the hands of a terrorist group or malicious nation-state that
modifies the Ebola virus to have a longer incubation period and increase
the transmission rate by a thousand fold, or build into Zika the
ability severely to alter a victim's DNA and render 95% of its victims
infertile.
Spread by mosquitoes or person to person, these new diseases would speed across borders, breaching all conventional defenses.
After
the incredible advances and proliferation of the use of the CRISPR
technique in the past several years, experts believe we are now looking
at a genetic arms race that is being conducted in research labs across
the globe.
Expect advances in medicine and
food sciences, but don't be surprised if the next global pandemic is
man-made and far worse than any we have seen before.
