Scientific iconoclasm and active imagination: synthetic cells as techo-schientific mandalas

Metaphors allow us to come to terms with abstract and complex information, by comparing it to something which is structured, familiar and concrete. Although modern science is “iconoclastic”, as Gaston Bachelard phrases it, scientists are at the same time prolific producers of metaphoric images themselves. Synthetic biology is an outstanding example of a technoscientific discourse replete with metaphors, including textual metaphors such as the “Morse code” of life, the “barcode” of life and the “book” of life. This paper focuses on a different type of metaphor, however, namely on the archetypal metaphor of the mandala as a symbol of restored unity and wholeness. Notably, mandala images emerge in textual materials related to one of the new “frontiers” of contemporary technoscience, namely the building of a synthetic cell: a laboratory artefact that functions like a cell and is even able to replicate itself. The mandala symbol suggests that, after living systems have been successfully reduced to the elementary building blocks and barcodes of life, the time has now come to put these fragments together again. We can only claim to understand life, synthetic cell experts argue, if we are able to technically reproduce a fully functioning cell. This holistic turn towards the cell as a meaningful whole also requires convergence at the “subject pole”: the building of a synthetic cell as a practice of the self, representing a turn towards integration, of multiple perspectives and various forms of expertise

The Machine Conception of the Organism in Development and Evolution: A Critical Analysis

This article critically examines one of the most prevalent metaphors in modern biology, namely the machine conception of the organism (MCO). Although the fundamental differences between organisms and machines make the MCO an inadequate metaphor for conceptualizing living systems, many biologists and philosophers continue to draw upon the MCO or tacitly accept it as the standard model of the organism. This paper analyses the specific difficulties that arise when the MCO is invoked in the study of development and evolution. In developmental biology the MCO underlies a logically incoherent model of ontogeny, the genetic program, which serves to legitimate three problematic theses about development: genetic animism, neo-preformationism, and developmental computability. In evolutionary biology the MCO is responsible for grounding unwarranted theoretical appeals to the concept of design as well as to the interpretation of natural selection as an engineer, which promote a distorted understanding of the process and products of evolutionary change. Overall, it is argued that, despite its heuristic value, the MCO today is impeding rather than enabling further progress in our comprehension of living systems

Foundations and profiles: splicing metaphors in genetic databases and biobanks

In this paper we explore new developments in genomics, in particular the move from data sequencing efforts like the Human Genome Project (HGP), to newer forms of data-driven genomic work that focus explicitly on the complicated relationship between genes and environment. We compare the use of a key term within the HGP, the metaphor of “foundation,” to the use of a different term, the metaphor of “profile,” within the GenomEUtwin consortium, an exemplar of “post-genomic” projects. By doing so, we attempt to re-think the role of language and metaphor in scientific projects and explore new developments in post-genomic research. These developments include: first, the movement towards an explicit and programmatic acknowledgement of the complexity of gene and trait relationships, second, the use of bio-informatics techniques as exploratory tools of discovery rather than as part of a more straightforward “decoding” effort, third, the development of network infrastructures that link up and provide access to a vast array of different databases, and fourth, the alignment between various disciplines and interests within biology, clinical work, and public health initiatives. We use the metaphor of “splicing” to emphasize the heterogeneous work of scientists engaged in “weaving together” the diverse set of ideas, interests, and players necessary for the success of large-scale scientific projects

The best and the worst of times for evolutionary biology

The 21st century will offer great opportunities, but also challenges, for the field of evolutionary biology, particularly in areas related to molecular genetic technologies, the environment, biodiversity, and public education. The coming decades promise to be both the best and the worst of times for the evolutionary disciplines

The ten grand challenges of synthetic life

The construction of artificial life is one of the main scientific challenges of the Synthetic Biology era. Advances in DNA synthesis and a better understanding of regulatory processes make the goal of constructing the first artificial cell a realistic possibility. This would be both a fundamental scientific milestone and a starting point of a vast range of applications, from biofuel production to drug design. However, several major issues might hamper the objective of achieving an artificial cell. From the bottom-up to the selection-based strategies, this work encompasses the ten grand challenges synthetic biologists will have to be aware of in order to cope with the task of creating life in the lab

\u27Are you playing god?\u27: Synthetic biology and the chemical ambition to create artificial life

Throughout history chemists have faced the accusation of ‘playing God’ or similar devilish associations, overshadowing all moral judgments of chemistry. The paper provides an ethical analysis of the accusation with focus on Craig Venter’s 2010 announcement of having produced the ‘first selfreplicating cell’. Against the deeper historical background of the ambitious projects that came to be known as ‘synthetic biology’, I describe Venter’s actual research and its international media reception. Then I analyze both the ethical and theological implications of creating living beings in the laboratory. In conclusion I argue that the Venter case, like many others cases from chemistry before, is a case of unfortunate science-public interaction that mislead both ethics and science

Genomic stuff: Governing the (im)matter of life

Emphasizing the context of what has often been referred to as “scarce natural resources”, in particular forests, meadows, and fishing stocks, Elinor Ostrom’s important work Governing the commons (1990) presents an institutional framework for discussing the development and use of collective action with respect to environmental problems. In this article we discuss extensions of Ostrom’s approach to genes and genomes and explore its limits and usefulness. With the new genetics, we suggest, the biological gaze has not only been turned inward to the management and mining of the human body, also the very notion of the “biological” has been destabilized. This shift and destabilization, we argue, which is the result of human refashioning and appropriation of “life itself”, raises important questions about the relevance and applicability of Ostrom’s institutional framework in the context of what we call “genomic stuff”, genomic material, data, and information

Neutral networks of genotypes: Evolution behind the curtain

Our understanding of the evolutionary process has gone a long way since the publication, 150 years ago, of "On the origin of species" by Charles R. Darwin. The XXth Century witnessed great efforts to embrace replication, mutation, and selection within the framework of a formal theory, able eventually to predict the dynamics and fate of evolving populations. However, a large body of empirical evidence collected over the last decades strongly suggests that some of the assumptions of those classical models necessitate a deep revision. The viability of organisms is not dependent on a unique and optimal genotype. The discovery of huge sets of genotypes (or neutral networks) yielding the same phenotype --in the last term the same organism--, reveals that, most likely, very different functional solutions can be found, accessed and fixed in a population through a low-cost exploration of the space of genomes. The 'evolution behind the curtain' may be the answer to some of the current puzzles that evolutionary theory faces, like the fast speciation process that is observed in the fossil record after very long stasis periods.Comment: 7 pages, 7 color figures, uses a modification of pnastwo.cls called pnastwo-modified.cls (included
