A Minimal Genome, A Giant Step? Research Ethics in the News

In late May the J. Craig Venter Institute (JCVI) announced the creation of the “First Self-Replicating, Synthetic Bacterial Cell.” (The research team’s report was published simultaneously: Gibson DG, …, Venter JC. Creation of a Bacterial Cell Controlled by a Chemically Synthesized Genome. Science. 2010 May 20. PubMed PMID: 20488990.) With $40 million and over a decade of work, the team produced the synthetic cell by piecing together a replica of a bacterial genome (Mycoplasma mycoides) and transplanting this DNA “software” into a cell from a related bacteria (Mycoplasma capricolum). When the cell began to replicate the information from its “synthetic genome,” the JCVI declared success.

What will be the scientific and social impact of this research? Both researchers and ethicists appear to be of two minds: the synthetic cell is big news, but maybe not worth the “hype” everyone is more than willing to supply. For example, while announcing JCVI’s discovery with great fanfare (suggesting solutions for the flu vaccine, greenhouse gas, and even the BP oil spill), Venter insists in The Wall Street Journal that this is not the creation of life ex nihilo. In fact, he refers us to Arthur Kornberg’s work in 1967 to make a copy of a virus. Perhaps the history lesson is meant to reassure the public; although considered by President Johnson to be “a very spectacular breakthrough,” Kornberg’s work was completed over forty years ago and, while the effort did have a scientific impact, we’re not overrun with zombies … yet.

Ethicists responded similarly: part “hype”, part reassurance. Arthur Caplan (in January 2009) reminded us that ethicists have been thinking and writing about the risks and benefits of synthetic biology for a long time. In fact, Caplan was one of the authors on paper published in 1999: Cho MK, Magnus D, Caplan AL, McGee D. Policy forum: genetics. Ethical considerations in synthesizing a minimal genome. Science. 1999 Dec 10;286(5447):2087, 2089-90. PubMed PMID: 10617419. Caplan echoes these reassuring sentiments in his recent Breaking Bioethics commentary: “The regulatory, social and legal challenges can be solved.” He, nevertheless, insists that grander issues might now be at stake:  “The real fallout from the Venter group’s achievement is subtle but more powerful. The scientists are chipping away at the view that there is something unique and unknowable about life itself. From this day forward, we know that the right chemical messages, presented in the right order and put in the right chemical context, can produce life.”

Julian Savulescu, quoted at BBC News, also looked at both sides of the coin. According to Savulescu the risks and benefits of synthetic biology are “in the far future,” but also “unparalleled”: “If this research goes in one direction Dr Venter may get the Nobel prize, but if it goes in another direction there will be no Nobel prizes to give because there will be no people to give them.”

On the very day of Venter’s press release, President Obama sent a letter to Amy Gutmann, the director of the recently formed Presidential Commission for the Study of Bioethical Issues. The Commission now has six months to complete “a study of the implications of this scientific milestone.” Reporting to the Science and Technology Advisor, Dr. John P. Holdren, the Commission will also develop recommendations for how the Federal government should anticipate and respond to similar scientific developments. Erik Parens, writing for the Hastings Center’s Bioethics Forum wonders if the new commission’s focus on “practical” questions will limit its ability to address the larger philosophical implications of synthetic biology. Although not responding directly to Parens, Jonathan Moreno takes a quick look at one of these big philosophical questions at Science Progress. Not unlike Venter’s reference to Kornberg, Moreno remembers early investigations of the idea that scientists are overstepping natural boundaries and “playing God.” By producing “an organic substance from non-organic matter,” chemist Friedrich Wohler crossed a “natural” boundary in 1828. This was a big deal for chemistry and for the philosophy of science. While Moreno, it seems, believes the ethical issues and philosophical questions are not insurmountable, he graciously opens the debate to a variety of voices: “Whatever challenge it may pose to our contemporary assumptions, it would be foolish to reject wisdom from any source in helping us decide where the path should lead, divine ones included.”

Readers looking for a thorough introduction to ethical issues of synthetic biology may wish to begin with:

Friedman, “Synthetic Biology,” in From Birth to Death and Bench to Clinic: The Hastings Center Bioethics Briefing Book for Journalists, Policymakers, and Campaigns, ed. Mary Crowley (Garrison, NY: The Hastings Center, 2008), 163-168.

The Synthetic Biology Project, established at the Woodrow Wilson International Center for Scholars and partnering with both The Hastings Center and the JCVI, also provides many resources on the subject, including:
