Building ‘Smart’ Cell-Based Therapies

(Nanowerk News) – A Northwestern synthetic biology team has created a new technology for modifying human cells to create programmable therapeutics that could travel the body and selectively target cancer and other sites of disease. Engineering cell-based, biological devices that monitor and modify human physiology is a promising frontier in clinical synthetic biology. However, no existing technology enabled bioengineers to build such devices that sense a patient’s physiological state and respond in a customized fashion.

Will Synthetic Biology Evolve into the Next Hot Field?

(Yahoo News) – Synthetic biology grew from a very old human desire to engineer living systems and make them do useful things for us. As genetic engineering of the 1970s has evolved into synthetic biology today, the technologies and economics for sequencing (reading) and synthesizing (writing) DNA have become optimized for large-scale DNA processing. This allows synthetic biologists to design and modify the genetics of living systems so that they produce a wide variety of materials for us that don’t occur in nature, such as drugs, biofuels, flavors, fragrances and more.

Math Modeling Integral to Synthetic Biology Research

( – A long-standing challenge in synthetic biology has been to create gene circuits that behave in predictable and robust ways. Mathematical modeling experts from the University of Houston (UH) collaborated with experimental biologists at Rice University to create a synthetic genetic clock that keeps accurate time across a range of temperatures. The findings were published in a recent issue of the Proceedings of the National Academy of Sciences.

Scientists Move Closer to Inventing Artificial Life

(National Geographic) – In a biological first, an international team has inserted a man-made chromosome into brewer’s yeast, producing a life form that thrives and successfully passes the designer genes on to its offspring. The “synthetic” biology advance—the first synthesis of a working artificial chromosome in an organism more complex than a bacterium—opens the door wider to man-made microbes that may someday be designed to manufacture better fuels, food, and medicines.

“Biological time travel”

(Harvard Magazine) – From glowing fish to bacteria that can count, synthetic biologists are now able to create life forms never before seen on earth. “Historians and Ecclesiastes be damned,” says Sophia Roosth, assistant professor in the history of science. “In the first decades of the twenty-first century, a number of things are new under the sun.” In a lecture last Wednesday drawn from her forthcoming book, Synthetic: How Life Got Made, Roosth, a Joy Foundation Fellow this year at the Radcliffe Institute for Advanced Study, described her analysis of recent attempts at “de-extinction,” the effort to recreate extinct or endangered species using modern technologies.

Synthetic Biology and Venter’s Life at the Speed of Light

Craig Venter’s book Life at the Speed of Light: From the Double Helix to the Dawn of Digital Life describes the completion of the first functioning organism with a completely synthetic genome and places this accomplishment within the context of the history of genetics. While several reviews can be found online, this article will look at the specific bioethics issues that arise in discussing Venter’s process of making a synthetic organism as well as his vision for a future where digital technology and biological information merge to potentially solve many of the world’s problems.

Venter’s goals are to determine a minimal genome necessary for life, create this genome in the lab, and create the necessary cellular machinery to operate the genome. In the book, he explores the definition of life, and feels that his research helps answer the question “What is life?”


Summary of the Process

Venter’s group began by synthesizing the genome of Phi X 174. Phi X 174 was the first virus genetically sequenced, so it was used as a test subject for the Venter group’s process for synthesizing long pieces of DNA in the laboratory. They wanted to use this well-studied genome to double check that their process was working. At that time, scientists had not successfully made long sequences of DNA in the lab without the DNA breaking or introducing errors. By 1999 the Venter group was able to successfully re-create the DNA sequence for Phi X 174 using their method.

While the media may have touted the construction of the Phi X 174 genome as “creating life in the lab” the Venter group did not consider it so because Phi X 174 is a virus, not a cellular organism. Venter considered this accomplishment merely one step toward the end goal of making an actual synthetic organism.

In 2007 the Venter group was able to reconstruct the genome of M. genitalium, a well-studied bacterial organism. This established a method by which they would then construct a genome that had never been constructed in the laboratory before. Additionally, they demonstrated that the genome of one bacterial organism can be placed into the cell of a different species of bacteria, which had its DNA removed, and the cell will behave according to the identity of new DNA. In the end, they synthesized a M. mycoides genome and placed it within a M. capricolum cell. Final tests showed that the organism behaved like a M. mycoides cell (Venter, 123).

Ethics Review

After the preliminary studies with Phi X 174, Venter funded a private review board to investigate the ethics and implications of making life in the lab. This group was headed by Arthur Caplan, at the time working at the University of Pennsylvania. The review was published in Science as “Ethical Considerations in Synthesizing a Minimal Genome.”

Additionally, because the Venter group had constructed a virus, and there were political issues associated with the potential for other countries making synthetic viruses, completion of the Phi X 174 also sparked an ethics review by the government’s National Science Advisory Board for Biosecurity on dual-use research.

Then, in 2010, when the J. Craig Venter Institute announced that they had created “the world’s first self-replicating synthetic (human-made from chemical parts) genome in a bacterial cell of a different species, President Obama had the Presidential Commission for the Study of Bioethical Issues evaluate the research and its implications. The Commission published a document entitled “New Directions: The Ethics of Synthetic Biology and Emerging Technologies” evaluating the ethical issues surrounding Venter’s work.

Both the independent review board and the Presidential Commission for the Study of Bioethical Issues brought up several key points, one of the more important of them is whether Venter actually created life in the lab. Both they and Venter point out that synthetic biology is really a form of genetic engineering (Venter, 83), so many of the same ethical concerns that were considered when the human genome project was happening apply to synthetic biology as well.

There are, however, a few additional bioethics issues that are specific to this technology:

  • The Venter group did develop a robust approach to making large sequences of DNA in the lab by inputting the desired code into the computer. While some question whether this technology can really be used to make a functioning bacterial cell, it does have implications for creating a synthetic virus. Viruses are rather simple organisms that consist of a container for holding DNA, the actual viral DNA (or RNA) that invades a cell, and sometimes, a virus will have some mechanism for inserting itself into a cell. The concern is that this technology may be used for bioterrorism. This is why the government board on dual-use technologies evaluated the research. While Venter sees his work as solving more problems than it creates, he considers this one of the key areas of concern (Venter, 155).


  • Because the bacterial cells with the synthetic DNA are capable of replication, there is potential to introduce synthetic organisms, ones without precursor parents, into the environment.  Unlike naturally-occurring organisms, these do not have an ancestral history. Venter lauds this as an accomplishment because, as he stated in the beginning of the book, he sees the scientific endeavor as understanding and controlling life (Venter, 8), and introducing new organisms into the environment is a type of control. However, the President’s Commission says that this can also be cause for concern. Indeed, they question whether synthetic organisms, once released into the wild, will be controllable “We are far from being proficient speakers of the language of life, and our capacity to control synthetic organisms that we design and release into the world is promising but unproven” (Commission, 22).


  • Synthetic biology is a changing field, and while ethical recommendations and considerations have been made, the President’s Commission believes that dialog, critique, and public education are important for this changing field (Commission, 15-16). To that end, the Commission developed some guiding principles that Venter mentions but does not discuss in detail in his book: 1) public beneficence, 2) responsible stewardship, 3) intellectual freedom and responsibility, 4) democratic deliberation, and 5) justice and fairness. (See The Commission’s report for details on each of these.)


  • Finally, there is a question of how to deal with patents. While the process to make a synthetic organism may be patentable, are synthetic genomes able to be patented? They do not fall under the category of “natural phenomena” because they were technically engineered. However, as we saw with the Myriad Genetics’ case, one cannot patent human genes.Additionally, there may be a question of how similar is too similar. In the case of Venter’s research, the synthetic genes are modeled on naturally occurring genes, but may have slight differences. This also brings up the question of whether living things can be patented at all, assuming Venter’s group did make a novel living organism in the lab.


Philosophical Points

While the goal of this article is to address bioethics issues, there are several philosophical issues that play an important role in Life at the Speed of Light that ought to be mentioned. The book begins by contemplating what the definition of life is. According to Venter, his experiment answers this question by showing that life is information, namely DNA.

A key theme throughout Life at the Speed of Light is Venter’s exasperation with vitalism. In this case, he is referring to the scientific use of the term “vitalism,” a term that was originally used to describe the belief that cells have a vital force that cannot be measured empirically. Venter, however, expands the term to mean a belief that life is anything more than chemistry (Venter, 17 and 18). In other words, he uses an antiquated notion to encompass anything other than his definition of life. For Venter, the information and complexity seen in the cell emerges out of chemical properties, and his group’s ability to replace the genome of one organism with another serves, at least from his point of view, as definitive proof that vitalism is an antiquated notion based on poor science:

The other major impact of the first genome transplants was that they provided a new, deeper understanding of life. My thinking about life had crystallized as we conducted this research. DNA was the software of life, and if we changed that software, we changed the species, and thus the hardware of the cell. This is precisely the result that those yearning for evidence of some vitalistic force feared would come out of good reductionist science, of trying to break down life, and what is meant to be alive, into basic functions and simple components. Our experiments did not leave much room to support the views of the vitalists or of those who want to believe that life depends on something more than a complex composite of chemical reactions. (Venter, 109)

Venter is uninterested in the implications of a purely reductionistic view of life and expressed surprise that the ethics board that he funded spent time in their Science paper discussing the religious and philosophical implications (Venter, 81). For Venter, ethics appears to be about permissibility. Is he doing anything illegal or that will cause religious groups to protest? The ethics committee said that they “could not find references in the Bible or other religious writings that forbade the creation of new forms of life” (Venter, 79). For Venter, this signified that he did his due diligence to appease those who may have philosophical or religious concerns about his work.

Finally, Venter addresses his critics’ claims that he did not actually make life in the lab, because he used already existing templates and cellular machinery (See, for example, page 32 of the Commission’s report). Some contend that he did not make life “from scratch.” Venter appropriately points out the ambiguity of the phrase, “from scratch,” and questions what his detractors would consider a completely synthetic organism (132). However, he does not adequately address the fact that the two species of bacteria were specifically chosen because their genetics were similar and therefore, the cellular machinery (organelles and proteins) used to read the DNA should be compatible between one species and the other. Furthermore, his group specifically chose M. mycoides as the DNA donor and M. capricolum as the host cell because they knew from other studies that the experiment does not work if M. capricolum is the DNA donor and M. mycoides is the host (Venter, 102). He likens the feat to trying to run PC software on a Mac (Venter, 112), but really, it is more like trying to get a Word document on a PC to open in the Office Program for Mac. However, in responding to his critics, Venter downplays the role of cellular machinery in order to advance the narrative that DNA is the essence of life.



This article is meant to address the book by Venter, rather than the entire field of synthetic biology. It is difficult to write about the bioethics issues in Life at the Speed of Light because Venter’s goal is to discuss the process and laud the benefits. It downplays the concerns, but assures the reader that the concerns have been adequately addressed.

Most disconcerting about the book is Venter’s disregard for any views contrary to his own or that critique his work. Venter discusses his own position with an air of rational superiority while he, himself, makes un-objective philosophical claims. He believes in the moral and intellectual superiority of scientists, and presumes that if scientists are doing synthetic biology, it can only serve for the public good and for furthering progress. His goal is to convince the public of the benefits of synthetic biology. While the book seems educational in nature, it is not so much about empowering the public to decide whether synthetic biology is safe, but rather to show them that it really is all under control.

Synthetic gene helps HIV vaccine hit shape-shifting foe

An HIV vaccine that uses a synthetic gene to trigger an immune response might offer a way to protect against the virus where others have failed. Most vaccines work by training immune cells called B-cells to produce antibodies against a virus. Another approach is to stimulate T-cells, which kill cells infected with the virus. This is known as inducing cellular immunity. (New Scientist)

Interview with Dr. Eric Drexler

Interview with Dr. Eric Drexler during his recent book tour for Radical Abundance (PublicAffairs, 2013).

“To begin with, it’s important to understand that the prospects I describe involve something more than nanotechnology in the present sense — they involve developments that are outside the fields of material science and much simple nanoscale devices. The long-range revolutionary potential of developments at the nanoscale will come from atomically precise manufacturing, a technology analogous to digital information technologies or 3D printing: a general-purpose way to make intricate patterns of something, in this case, patterns of advanced materials that form advanced products of all kinds.” (Nanotechnology Now)

Do-it-yourself biologists doing no harm, survey finds

There’s little to fear from the existing Do-It-Yourself Biology (DIYbio) movement, concludes a report released today by the Woodrow Wilson International Center for Scholars in Washington, D.C. “There’s been a lot of debate in the biosecurity community about what DIYers may or may not be doing, from making narcotics to pandemics to viruses that kill heads of state (I’m not joking),” writes Wilson fellow and report co-author Daniel Grushkin in an e-mail to ScienceInsider. He hopes the report will “dispel a lot of these myths, so that the discussion can move beyond suspicion and risks, and start focusing on opportunities.” (Science)
