Biosecurity Background Information
As biological techniques become cheaper and easier to perform, and information becomes
increasingly accessible to anyone interested to find it, the chance of misuse of these techniques and
information increases. The concept of dual use research is that legitimate scientific inquiry has the
potential to be used out of its original context for inappropriate usage up to and including
development of bioweaponry. As information is absorbed and adopted into the greater community
the scientific and governmental communities lose their controlling positions over the research
questions, which are explored, the methods used to explore them, and the security of the
information once obtained. It is clear that the management of dual use research cannot be left solely
in the hands of government regulators; blanket restrictions designed to manage research activities
from academia through the biopunk movements may require sacrificing the speed and freedom
under which current scientific inquiry is conducted.
The responsibility of the researcher to prevent misapplication of methods or findings is becoming a
serious ethical issue. Investigators are in a unique position; as subject matter experts they are the
most qualified individual to identify potential dual uses for the techniques and results of their work.
Awareness of this potential and a real consideration of the repercussions should their findings be
published must be weighed against the cultural (and often financially driven) incentive to “publish or
perish.”
The first consideration for dual use research is the potential for a technique to be adapted for the
development of bioweapons. Bioweapons have been widely used throughout history; most

bioweapons were developed under the watchful eyes of the scientific community and adapted from
simple and widely used techniques. In 1925, the Geneva Protocol prohibited use of bioweapons and
this sentiment was ratified by the US senate in 1975. In 1975 the Biological and Toxin Weapons
Convention (BTWC, or more formally The Convention on the Prohibition of the Development,
Production and Stockpiling of Bacteriological (Biological) and Toxin Weapons and on Their
Destruction) was also enacted. This treaty prohibits the development, production, stockpiling, and
acquisition of biological and toxin weapons, and required the destruction of existing inventories and
delivery devices. As with the scientific community, the question of responsibility, accountability,
and enforcement has not been sufficiently explored at the nation’s level.

The future of bioterrorism is moving towards the home brew methods. Several examples of dual
use research have been reported using methods, equipment, and materials taken completely from

online resources including synthesis of the polio virus and influenza viruses. One study, which
caused concern in the community about the potential for dual use research described improvements
of drug delivery via aerosol methods, which could potentially be used for the widespread delivery of
toxic agents or harmful biologics.
Dual use research has been used to break the law in a non-conventional way. The biopunk
movement is a growing trend. A biopunk is a hobbyist who experiments with DNA and other
aspects of genetics. These individuals perform high-tech biological experiments in their closets,
basements and garages. They also find innovative ways to inexpensively produce the necessary
equipment for these high-tech experiments. An example of one of these experiments is the
transfection of tobacco plants with THC gene found in marijuana. They found that it was quite
possible to achieve THC expression in the transfected tobacco plants. The study is an example of
research that could be duplicated by biopunks in order to circumvent the law. It shows that not all
people are interested in technological advancements in biology are interested or willing to create
bioweapons.
There is now the question of what to do about information pertaining to biological research.
Researchers could self-police to ensure that only responsible and trusted parties have access to their
data. Journals and institutes could suppress certain information in papers such as materials and
methods. Researchers could choose not to publish in order to avoid the information getting into the
hands of dangerous individuals. All of these choices will end up in the impediment of scientific
findings.
But something must be done to safeguard the public.
Dual Use Case Study: Rehashed
Most college students know that there is nowhere good to buy weed on campus. So they invented
it. Two student roommates were riding the golf cart around campus after their biotech class and
were all fired up about transfection methods and all of the cool things that they could make if they
had the supplies. Then it hit them- they could do this.
So they went to their best friend- Google. Of course, everything they could ever ask for was there
and they were so excited. They converted one of the bathrooms in their apartment into a wet lab

using equipment and supply purchased online and were able to save quite a bit of money by making
their own equipment, like the compound microscope they made by removing the camera off of a
webcam and turning it upside down; $10- score!! One of their dads even came and checked out
their little operation and was really proud of the lab setup they had put together- it was just like
when he was in college building CB radios with his friends and hacking the radio waves.
The two students practiced a few times on bacteria they grew on potatoes and then they had this
great idea to make a glowing rose bush for one of their girlfriends. So the time had come!! They
had only put between the two of them about $200 in investment and they were ready to take the
leap and try something that would make them some money back. Just outside of their apartment
window there is this obnoxious ivy plant that grows clear across the window and makes it hard to
open. They decided to take a clipping from this ubiquitous and innocuous plant and transfect it
with the genes for THC1 (not hard to find, look on Google).
They researched the literature and discovered this had never been done before, it was novel, and it
had both commercial and scientific value. They found lots of support on some BioPunk websites
and Blogs, and actually attended a few seminars where they were able to tweak our technique to get
it just right. They grew their new friend “Potty the Potted Plant” big and strong, and got ready to
test it out. They dried some leaves and processed them according to the instructions they found on
line. So, they smoked it, as a trial run- they couldn’t sell a product without ensuring its safety and
efficacy. They suffered no ill side effects although one of the roommates was sure that there was a
raccoon trapped in the room with them-they attributed that to not drying the ivy thoroughly.
Anyhow, once they ensured that it was perfectly safe to use, they began taking clippings and selling
little houseplants to their fellow students.
With the money they made they were able to reinvest into their enterprise and purchase some
upgraded equipment. They took a poll of our fellow students asking what drugs they would like to
be available through either inhaled or eaten vegetation; top requests included contraceptives, acne
relief, and allergy relief. Some of the more mischievous students suggested that they transfect plants
to produce botulism toxin or morphine. They had started tinkering around with different herb types
and had some promising results so far. Several of their friends have asked if they could help them to
develop these ideas and then went to brag about their work to some professors.

Here is where the trouble comes in… One of their professors approached them the other day and
told them off for breaking the law by providing THC to students even though it was not in
marijuana. He commended the students for being so enterprising and for moving into further
interests to meet demand, but he felt that he would have to turn them in to law enforcement citing
that we were performing research on their friends and dealing drugs. Another one of their
professors suggested that they file a provisional patent and write a paper to submit to a journal. They
are too afraid of the legal implications to do either of those things.
They just applied what they had learned and were smart enough to capitalize from it. Isn’t the
whole point of Socratic method and the university system to give students the tools to freely
investigate and to foster an environment of entrepreneurism and creativity? They never wanted to
go to jail.

Ethical questions to consider regarding Dual Use research:

Whose responsibility is it to monitor what research is published, and what
equipment is sold?
The vendor and the publishing journals should be responsible for monitoring what they sell
and publish. If there is something blatantly dangerous that they are providing than they
should prevent that from being available. Unfortunately, as of today, they are not
responsible.

Is it acceptable to publish research that could be used for bioterrorism?
Journals should not publish research that could be used for research unless they omit
information that could help potential terrorists to duplicate the experiment such as the
materials and methods sections. Researchers that are known and trusted should be allowed
to have access to the information if they are planning to conduct further research.


Should you publish techniques to purify or create recombinant production of toxins?
It is a moral obligation of journals not to allow dangerous information to fall into the wrong
hands. Morally giving someone the information that they need to create a toxin that could
kill thousands of people is very close to creating it yourself.

Should you allow universities to hold potential bioweapons?
In this situation one should consider the potential consequences. Universities do not have
the policies and procedures in place to properly secure their research materials that could be
used as bioweapons. If they had the proper security than perhaps it would be a different
situation but as of now they should not have these potential bioweapons.

Is it appropriate for policy makers to limit researchers in dual use research?
The distinction between morality and the law is important to consider in this case. In many
cases, the law has not limited the research that scientists can perform. But because it is not
necessarily illegal, does not mean that it is not immoral. In some circumstances the research
that one conducts has beneficial possibilities that outweigh the bad but in many situations
they do not.

Whose responsibility is it to determine whether or not research could be used for
malicious intent, and whether or not to publish?
It is very difficult to determine what is “wrong” to publish due to the fact that many people
disagree about the quantification of “beneficial” or “bad” in this case. The journals need to
have an ethics committee in order to determine what information should be published and
what should not.
