Biotechnology is
one of the world's fastest growing commercial sectors. Since 1992,
the number of biotechnology companies in the United States
alone has tripled. These firms are research-intensive, every day
bringing into the marketplace new methods and products that
may reshape medical practices and human performance, allowing for
unprecedented improvements in health care.
Many of
biotechnology's benefits are dual-use, increasing the possibility
that knowledge, skills, and equipment could be adapted for use as
biological weapons. As the global biotechnology industry
expands, the U.S. government should therefore increase its capacity
to exploit biotech advances for national security.
The challenge of
exploiting cutting-edge biotechnology will be different from
the way the Pentagon harnessed science and technology for national
security during the Cold War. Rather than driving the
biotechnology revolution, the federal government will need to
figure out how best to utilize and adapt the products
developed by a multibillion-dollar transnational industry that
already has the money and capacity for research and
development.
To keep up, the
federal government must adopt legislative, policy, and
organizational innovations. These should include promoting
international liability protection for developing and deploying new
national security goods and services, promoting scientific travel
and exchanges, and assigning a lead agency to coordinate
biotechnology exploitation for national security.
From There to
Here
Biotechnology
refers to any technological application that uses living
organisms to make or modify products for explicit use, specifically
through DNA recombination and tissue culture. Gregor Mendel first
described the role of genes through his research on "dominant and
recessive factors" in the 1860s. By the 1940s, scientists were
aware of DNA, and James Watson, Francis Crick, and Rosalind
Franklin modeled its structure in the 1950s.
In 1970, the
discovery of enzymes, which break apart and connect snippets of
DNA, allowed for the creation of genetically modified organisms.
This bore fruit by the early 1980s, when scientists managed to
genetically modify bacteria to produce human insulin, which is now
the principal source of insulin for diabetics.[1]
Recently, major
advances in information technologies have led to the
development of bioinformatics.[2] Bioinformatics focused
initially on creating and storing biological and genetic
information, most notably in the Human Genome Project. Scientists
are now combining this information into a comprehensive
picture, enabling researchers to study how different diseases alter
these activities. Combining advances in genomics and information
technology has significantly enhanced the industry's capability to
bring new products to the marketplace.
Many of the
advancements in biotechnology are dual-use. The technology that may
revolutionize medical care by providing faster-acting and more
effective drugs could also be used to field more lethal biological
weapons. Thus, federal agencies have a clear imperative not
only to exploit the advantages of new developments, but also to
anticipate and prepare countermeasures for how potential
adversaries might exploit these medical advances.
Current
Research
Much of the
current biotech research focuses on agent detection, vaccines, and
treatment. Scientists are studying the immune systems of primitive
organisms, such as jawless fish, to garner greater
understanding of the human immune system and to develop new
antibody therapies.[3] They are also studying how diseases infect
and affect human cells. For example, recent research indicates that
the family of bacteria that includes bubonic plague blocks
immune system responses using a protein related to one naturally
found in humans.[4] Scientists are also investigating ways to
create vaccines that work against whole classes of disease-causing
organisms and to boost the human immune system in general.[5]
Research is also
underway to counter the rise of multidrug-resistant bacteria.
Scientists are investigating the use of bacteriophages, which
are viruses that prey on bacteria, as a means to fight infectious
disease. Ironically, research on bacteriophages began in the early
20th century but declined after the discovery of antibiotics. In
the summer of 2006, the U.S. Food and Drug Administration approved
the use of a bacteriophage preparation on meat as an anti-microbial
agent against Lysteria bacteria.[6]
Better vaccines
and treatments could provide permanent immunity to all "classic"
biological agents or at least reduce their lethality to a
considerable degree. In October 2006, the Institute for
Soldier Nanotechnologies at the Massachusetts Institute of
Technology announced the development of microscopic pumps that
would allow rapid testing of blood and other fluids by pumping them
into a "lab on a chip," which would detect biological or chemical
agents.[7]
Argonne National
Laboratory is also developing its own biochip detection
technology.[8] This "lab on a chip" research points to the
feasibility of rapid biological agent detection, allowing
individuals to know whether they have been exposed within minutes
rather than days. It may even be possible to develop implantable
biosensor chips that would continuously monitor for exposure
to biological agents.[9]
The Future of
Biotechnology
Future advances
in biotechnology will continue to improve the protection of both
the general public and military personnel from deadly biological
agents. The creation of broad-spectrum vaccines may give the public
health community the ability to vaccinate the country's entire
population against both endemic diseases and biological weapons. A
bioweapon inoculation may someday be as common as other
childhood vaccinations.
Besides disease
detection and vaccines, biotechnology has numerous other
potential applications. The military is exploring the use of
biomimicry, which uses natural biological systems or material as an
inspiration for solving engineering problems. For example:
- In 2002, scientists discovered how geckos stick themselves to
smooth surfaces using van der Waal's forces-the weak natural
attraction between atoms-and were then able to re-create the
surface of a gecko's foot artificially.[10]
- The Defense Advanced Research Projects Agency is researching
devices that mimic geckos' use of van der Waals force to enable
soldiers to climb buildings without ropes or ladders.[11]
- Scientists are also researching spider silk and abalone shell
to create stronger, lighter armor for personnel and vehicles.
- Other projects include developing organic solar cells and a new
generation of sensors and optics derived from biological and
silicon-based systems.[12]
The next great
step in biotechnology is proteomics: the direct manipulation
and construction of proteins. While DNA instructs cellular
mechanisms in how to operate, proteins do the actual work inside
and outside of cells. Proteins are found in everything from papayas
to snake venom. Because protein structure and composition is much
more complex than DNA, protein analysis is much more difficult and
time-consuming. However, understanding how proteins are
constructed and how they behave promises to be as great an advance
in biological science as understanding DNA was in the 20th
century.
If advances in
biotechnology continue, constructing a completely artificial
organism from the "ground up"-creating synthetic DNA and proteins
from raw materials and then combining them to form living cells-may
be possible in the not too distant future.
National Security
and Biotechnology
The challenge for
the federal government is to figure out how to leverage
cutting-edge biotechnology for national security purposes.
Before 2001, the Department of Defense (DOD) was the primary arm of
the federal government in funding biological defense and research
related to national security. The DOD research program focused
primarily on the battlefield uses of biotechnology.
The events of
9/11 and the post-9/11 anthrax letters shifted the focus to
the American people's vulnerability to biological threats. In
many respects, the DOD research was not directly applicable to
other biodefense national security needs. For example, DOD
immunization programs assume that the individuals to be immunized
will be generally healthy and young. On the other hand,
immunizations for a general population in the event of
biological weapons attack would have to consider the effects
of vaccines on old and young people and on individuals with medical
conditions who might have weakened or compromised immune systems
and react very differently to a vaccine developed by the
military.
To apply research
to broader national security concerns, the National Institutes of
Health (NIH) under the Department of Health and Human Services
(HHS) received the bulk of increased funding for developing
biodefense measures.[13] In recent years, in addition to HHS and
DOD, many other federal agencies have initiated biotechnology
research related to national security, including the recently
established Department of Homeland Security (DHS). While much of
the research in DOD, HHS, and other federal entities involves
detecting, protecting against, and mitigating biological
attacks and pandemics, it also involves other products related to
national security, including human performance enhancement (such as
reducing the effects of stress and fatigue) and battlefield medical
treatment. There is a plethora of ongoing programs.
The Pentagon has
considerable experience and capacity for medical research and
development of products related to national security, but this is
virtually a new mission for the NIH, which historically has
focused on basic scientific research.[14] The U.S. Army Medical
Research Institute for Infectious Diseases has unique research
facilities and expertise in biowarfare defense. On the other hand,
the DOD's record with respect to developing and producing vaccines
has engendered significant controversy.
The post-9/11
expansion of the government application of biotechnology to
national security has not been matched by organizational
innovations to manage and integrate programs more
effectively. DOD, DHS, and NIH research programs are not
routinely coordinated, and NIH policies prohibit funding other
federal institutions. Thus, NIH programs cannot utilize DOD
scientists who may have valuable knowledge and experience relevant
to NIH national security research. In some cases,
government-sponsored research duplicates other programs, and
opportunities for complementary research programs are missed.[15]
Enlisting the
Private Sector
Harnessing the
vast capabilities of the private sector has proven similarly
challenging. Compared to potential commercial buyers, the
government is a modest-sized customer for biotech firms. There are
also other issues. After 9/11, insurance skyrocketed for
technologies developed for homeland security. While the demand for
new security technologies has swelled, companies must weigh the
pressure to rush new products to the marketplace against their
liability risks.
In 2002, Congress
enacted the Support Anti-Terrorism by Fostering Effective
Technologies (SAFETY) Act[16] to encourage companies to continue
researching and developing biotechnologies vital to homeland
security. The act protects companies from litigation if their
products fail during a terrorist attack or are harmfully
employed by terrorists. The DHS has shown some success in
implementing the legislation and granting SAFETY Act protections to
goods and services that are employed to prevent or respond to
terrorist threats. However, companies do not enjoy similar
protections from other countries when the technologies are
deployed outside the United States or adopted by U.S. friends and
allies.
The government
also has a mixed record in encouraging the private sector to
develop new national security capabilities. In 2004, the President
announced the implementation of Project Bioshield to accelerate
research on and development, purchase, and availability of
effective medical countermeasures against biological,
chemical, radiological, and nuclear agents. The program provided $6
billion over the next 10 years to private companies for
research and development of next-generation countermeasures
against anthrax, smallpox, and other infectious agents and
antidotes against chemical and radiological threats. To date, the
effort has yielded meager results.[17]
The response to
9/11 has introduced another difficulty in advancing
biotechnology research in the United States. After the terrorist
attacks on New York and Washington, the United States imposed a
number of additional requirements on visa issuance and monitoring
to thwart travel by terrorists. These measures included more
rigorous registration and monitoring of foreign graduate students,
mandatory interviews of all overseas visa applicants, and requiring
visa holders to return to their countries of origin to renew their
visas.
These measures
have had unintended consequences, including deterring top
graduate students from coming to the United States, making
scientific exchanges more difficult, and even prompting
companies and academic and scientific associations to move
meetings, conferences, and research facilities outside of the
United States. As a result, the United States has become less
competitive in many key scientific areas, including
biotechnology.[18]
Moving Forward
The United States
has no room for complacency. Without better policies, programs, and
management, it risks losing its competitive advantage in
exploiting biotechnology for national security. Congress and
the Administration should act to set the right conditions for the
government to adopt commercial biotechnology developments.
Specifically, they should:
- Restructure national security biotechnology programs.
While increased funding has transformed it into the leading
federal agency in biosecurity research, the NIH is
inexperienced and unproven in its ability to develop products.
Likewise, the DHS has yet to demonstrate that it can produce
cutting-edge biotechnology advances. Conversely, the DOD has
significant experience and skills in developing biodefense
countermeasures.
To the maximum extent possible, research programs should be
consolidated under a single agency. Where consolidation is not
practical, a more effective management structure is needed to
leverage the advice and expertise in different agencies in support
of NIH programs.[19]
- Encourage other countries to adopt SAFETY Act
protections. While the SAFETY Act has been successfully
implemented in the United States, it does not protect companies
from litigation abroad. Consequently, companies that
operate outside of the United States have shied away from
contributing to biosecurity because of the potential risks.
The Administration should develop a strategy to encourage other
countries to adapt similar protections. The U.S. strategy
should take a regional approach, beginning with the European Union
and Japan.
- Reform visa issuance and management. U.S. national
security and competitiveness rely heavily on people's ability to
travel to the United States, but the current visa system is
unnecessarily depriving the United States of many of the world's
best and brightest scientists, students, and entrepreneurs.
Long wait times for personal interviews are among the most
frequently cited factors that make travel to the United States
difficult.
- Congress should remove the requirement for personal
interviews of virtually all non-immigration visa applicants and
restore the Secretary of State's ability to waive personal
interview requirements. The U.S. should begin using electronic visa
applications to reduce applicants' travel expenses and should
reduce processing times to 30 days or less. All of these reforms
can be implemented in a manner that makes international travel both
more convenient and more secure.[20]
Making the Nation
Safer
Dual-use
biotechnologies developed in the private sector offer powerful
tools to protect Americans from biological threats and to increase
the military's operational capabilities. Congress and the
Administration should not only be aware of this growing field,
but also act to ensure that the private sector- which is making the
largest investment in basic research and product
development-remains competitive. Specifically, the U.S.
government should streamline the federal government's capability to
fund and adapt new technologies, work to expand litigation
protection beyond the country's borders, and further reform U.S.
visa issuance and monitoring programs.

the use of databases and analytical tools for genome analysis and
innovations in molecular biology. One study holds that
bioinformatics can reduce the cost of drug development by 18
percent and cut one year from developmental timelines. "The Race to

Among its many applications to biowarfare, bioinformatics can
facilitate the identification of pathogens. For example, see D. A.

(July 16, 2007). Bioinformatics also holds great promise in
developing therapeutic responses to a bioattack. For example,
studies show that variations in individual responses to therapeutic
drugs are affected by genetic polymorphisms (variations in enzymes
caused by slightly different amino acid sequences).
Pharmacogenetics employs bioinformatics to assist in decoding and
mapping millions of polymorphisms across the human genome, which
can provide insights into the links between disease-causing genes
and drug-response genes, facilitating the development of new
therapeutic strategies. Michael M. Shi, "Diagnostics Meets
