Challenges of our own making

The successful transplantation of a synthesized genome highlights unresolved ethical and security issues posed by synthetic biology.

Who gets to imagine the future where science and technology are concerned? If we are creating new objects, who is responsible for the proliferation of good consequences and the prevention of bad ones? These perennial conundrums were aptly posed last July by the social scientist Sheila Jasanoff of Harvard University at a high-level conference on synthetic biology (see

Events last week illustrated their continuing relevance. Scientists led by Craig Venter published the first successful transplantation of a synthesized genome into a recipient cell (D. G. Gibson et al. Science doi:10.1126/science.1190719; 2010). The feat was a technical tour de force, requiring the accurate synthesis of a slightly modified genome of the bacterium Mycoplasma mycoides — all 1.08 million base pairs of it — followed by its successful insertion into a related species, Mycoplasma capricolum, and then the demonstration of replication of descendant cells exhibiting the characteristics of M. mycoides (see pages 406 and 422).

As many biologists were quick to point out, this was not the synthesis of life, nor indeed of a cell. But it was the first time that an organism had been put together with DNA constructed from specifications in a computer database, albeit derived from an existing organism rather than conceived from scratch. The long-anticipated development is a landmark in synthetic biology — a field that is burgeoning not only in its science and engineering but also in the discussions that surround it.

Credit is due both to the pioneers of the field for fostering open deliberations about the research-community, societal and ethical issues surrounding synthetic biology, and to the Alfred P. Sloan Foundation of New York for its long-standing support of these efforts. Unfortunately, such discussions repeatedly point to key concerns without resolving them. The achievements reported last week underline the need to do better.

“Concerns need to be developed beyond the knee-jerk soundbite.”

A prime example is the lack of international governance for synthetic biology, not least in relation to security issues. The European Union, the Organisation for Economic Co-operation and Development as well as national governments such as those of the United States and, to a lesser extent, China are engaged. But none seems willing to take the lead in establishing an international framework of governance and standards.

Another chronic security issue is the growth of do-it-yourself synthetic biology. The construction and transplantation of whole genomes remains beyond the capacity of most labs, although both may be routine within five years. But the ability to undertake hazardous biology in the garage is already with us. With trust being so important in science, universities and individual investigators are almost certainly not attentive enough to security risks. Nor are governments: the very possibility of malign synthetic biology, whether by states or eventually by 'biohackers', only reinforces the need for a much more extensive worldwide network of centres able to detect emerging infections.

Meanwhile, the anticipated power of synthetic biology leads back to the larger, as-yet-unresolved questions that Jasanoff posed. US President Barack Obama took a belated step in the right direction last week when he asked his bioethics council to consider the wider significance of synthetic biology and to report back in six months. But other organizations — ethical, environmental, medical and commercial — also need to join the discussion.

If its visions can be fulfilled, the power of synthetic biology is profound. The extensive discussions that have already taken place have revealed no significant new moral or societal constraints on its full realization. Accordingly, where there are concerns, they now need to be developed beyond the knee-jerk soundbite. Those inclined to worry about synthetic biology should take only small comfort from the fact that the complexity of organisms makes it so difficult to deliver.

    You can have ethics guidelines, recommendations and what not but if industry finds synthetic biology with commercial applications no amount of guidelines are going to stop them. Politicians are easily persuaded to do industry interests because of political funding and lobbying. The lack of regulation of genetic engineering/genetically modified organisms is one of the many examples where politicians and regulators have succumbed to industry needs even if initially lofty guidelines by scientists were put in place.

    During George W Bush administration, Secretary of Agriculture, Ann Veneman, was from Monsanto. Linda J. Fisher, ex-Monsanto official, was nominated by Bush to be second-in-command at the Environmental Protection Agency (EPA). Donald Rumsfeld, the defence secretary, was president of Searle Pharmaceuticals when it was bought by Monsanto. John Ashcroft, attorney general, received $10,000 from Monsanto for the elections, the most the company gave to any congressional candidate. Bill Clinton administration too was very chummy with the GE industry.

    Top journals like Nature and Science receive so much revenue from biotech and pharmaceutical company advertisements and sponsorhips. This could influence them about the two industries and could affect their publication preferences. The parent body of Science, the AAAS, its annual meetings are sponsored by industry especially biotech and big pharma. Again this could influence their publication preferences.

    We should learn from our past mistakes with regard to Nuclear power, GMO & other field of science developments. How far rules & regulations have rightly controlled these debatble issues? Just like anyother scientific development Synthetic Biology is again going to be boon for the humanity only if we use it for consttructive purposes & for that an impartial, globally uniform rules & regulations are need of the hour.
