The existing literature on the development of recombinant DNA technology and genetic engineering tends to focus on Stanley Cohen and Herbert Boyer's recombinant DNA cloning technology and its commercialization starting in the mid-1970s. Historians of science, however, have pointedly noted that experimental procedures for making recombinant DNA molecules were initially developed by Stanford biochemist Paul Berg and his colleagues, Peter Lobban and A. Dale Kaiser in the early 1970s. This paper, recognizing the uneasy disjuncture between scientific authorship and legal invention (...) in the history of recombinant DNA technology, investigates the development of recombinant DNA technology in its full scientific context. I do so by focusing on Stanford biochemist Berg's research on the genetic regulation of higher organisms. As I hope to demonstrate, Berg's new venture reflected a mass migration of biomedical researchers as they shifted from studying prokaryotic organisms like bacteria to studying eukaryotic organisms like mammalian and human cells. It was out of this boundary crossing from prokaryotic to eukaryotic systems through virus model systems that recombinant DNA technology and other significant new research techniques and agendas emerged. Indeed, in their attempt to reconstitute 'life' as a research technology, Stanford biochemists' recombinant DNA research recast genes as a sequence that could be rewritten thorough biochemical operations. The last part of this paper shifts focus from recombinant DNA technology's academic origins to its transformation into a genetic engineering technology by examining the wide range of experimental hybridizations which occurred as techniques and knowledge circulated between Stanford biochemists and the Bay Area's experimentalists. Situating their interchange in a dense research network based at Stanford's biochemistry department, this paper helps to revise the canonized history of genetic engineering's origins that emerged during the patenting of Cohen-Boyer's recombinant DNA cloning procedures.

Efforts to improve the means to diagnose and treat human genetic diseases have a long history in biomedical research and medicine. Now, preimplantation genetic diagnosis provides a new way to prevent the transmission of certain types of human genetic diseases to the next generation. It is an alternative to elective termination of pregnancies.PGD is used to test for genetic diseases that are due to defective single genes or abnormal chromosomes within days of fertilization and prior to the establishment of pregnancy. (...) The procedure essentially begins with the biopsy of one or more cells of a cleavage stage or blastocyst stage preimplantation human embryo that has been produced by in vitro fertilization. In certain cases, PGD can be done on polar bodies—discarded by-products of egg formation containing excess chromosomes—of unfertilized eggs. Then, the cell, or a polar body, is placed into a tube for single gene analysis ), or for chromosome analysis by spreading the nucleus of the cell on a microscope slide ). (shrink)

The aim of this paper is to discuss a key question in the history and philosophy of medicine, namely how scholars should treat the practices and experimental hypotheses of modern life science laboratories. The paper seeks to introduce some prominent historiographical methods and theoretical approaches associated with biomedical research. Although medical scientists need no convincing that experimentation has a significant function in their laboratory work, historians, philosophers, and sociologists long neglected its importance when examining changes in medical theories or progress (...) in scientific knowledge. The reason appears to have been the academic influence of the then dominant tradition in the history of ideas, but was also due to a misconception of what could usefully be termed the view on “historical ontology.” During the last two decades, there have been many books and research articles that have turned towards the subject, so that the study of experimental practice has become a major trend in the contemporary history and philosophy of medicine. A closer look at the issue of laboratory research shows that concepts in medicine and the life sciences cannot be understood as historically constant, free-standing ideas, but have to be regarded as dependent on local research settings. They often carry particular “social memories” with them and thus acquire important ethical implications. (shrink)

Studies on ‘Big Science’ have shifted our perspective from the complexity of scientific objects and their representations to the complexity of sociotechnical arrangements. However, how scientists in large-scale research attend to this complexity to facilitate and afford knowledge production has rarely been considered to date. In this article, we locate organizational complexity on the level of organizing practices that follow multiple and divergent logics. We identify three strategies of managing organizational complexity, drawing on existing literature on large-scale research as well (...) as own empirical research. The three strategies are: segmenting research infrastructure, introducing elements of bureaucratic governance, and implementing standards and standardization. We illustrate these strategies with examples from our empirical case study on experimental particle physics research at CERN’s Large Hadron Collider. While the strategies we identified help to cope with the complexity of some organizational tasks by dividing, ordering, or mediating between divergent organizational logics, we find that organizational complexity overall is not reduced but rather displaced. We argue that dealing with complexity is a dynamic and ongoing process, which inevitably generates novel organizational complexity. (shrink)

This paper examines processes of translation through which molecular genetic technologies and practices are incorporated into environmental health research and regulation. Specifically, it considers how scientists, risk assessors, and regulators have used genetically modified mouse models to translate across scientific disciplines, articulate emergent molecular forms, standards, and practices with the extant? gold standard,? and establish roles for molecular knowledge in risk assessment and regulation. Noting variation both within and between regulatory agencies in responses to data from these models, the article (...) describes also the role of public-private networks and their effects on professional and institutional imperatives which shape regulators? responses to the potential applications of these models. The conclusions address the importance of translation for understanding the wider implications of the molecularization of environmental health science. (shrink)

This article analyses 1,073 e-mails that were hacked from the Climatic Research Unit at the University of East Anglia in November 2009. The incident was popularly dubbed 'Climategate', indicating that the e-mails reveal a scientific scandal. Here we analyse them differently. Rather than objecting to the exchanges based on some idea about proper scientific conduct, we see them as a rare glimpse into a situation where scientists collectively prepare for participation in heated controversy, with much focus on methodology. This allows (...) us to study how scientists communicate informally about framing propositions of facts in the best possible way. Through the eyes of science and technology studies, the e-mails provide an opportunity to study communication as part of science in the making across disciplines and laboratories. Analysed as 'written conversation' the e-mails provide information about processes of consensus formation through 'agonistic evaluations' of other scientists' work and persuasion of others to support one's own work. Also, the e-mails contain judgements about other groups and individual scientists. Consensus-forming appeared as a precarious activity. Controversies could be quite resilient in the course of this decade-long exchange, probably reflecting the complexity of the methodological challenges involved. (shrink)

In this article I consider some central aspects of the naturalist philosophy of science and science and technology studies in dealing with the contested status of technoscience in medicine. Focusing on the concepts of realism and representation, I argue that theories of science-as-practice in naturalist philosophy of science should expand their scope so as to reflect more thoroughly on the social and political context of technoscience. I develop a hermeneutic of technomedical objects in order to highlight the internal connectedness between (...) social action, material agency, and the actions of scientific communities. The framework thus developed is used to re-consider the genomic turn in medicine. Pointing to the discrepancies between socially dominant representations of genomic technology and the actual interventions brought about through those technologies, I raise the question of how and where to address problems of theory and policy.

This article analyzes the National Science Study produced by the Republican-dominated U.S. Congress in the mid-1990s to see if the priorities of S&T policy were changing, if state agencies were being reorganized to achieve new priorities, and if universities were expected to work closely with industry in reconfigured agencies. Also analyzed was the economic composition of board members of eight S&T policy organizations that informed the National Science Study. It was found that, generally, Republican policy supported both basic science and (...) civilian technology policy but did not advocate reorganization of state administration of S&T. However, a number of the S&T policy groups pushed for the establishment of a separate mission agency for civilian technology. This suggests that conceptualization of a unitary social contract between science and society or iterated principal-agent relations expressing the interaction of science and society are insufficient because there may be multiple social contracts and many principals and agents.

This paper explores what it takes for research laboratories to produce valuable knowledge in academic institutions marked by the coexistence of multiple evaluative frameworks. Drawing upon ethnographic fieldwork carried out in two UK-based epigenetics research laboratories, I examine the set of practices through which research groups intertwine knowledge production with the making of scientific, health, and wealth value. This includes building and maintaining a portfolio of valuable resources, such as expertise, scientific credibility, or data, and turning these resources into assets (...) by carefully organizing and managing their value. Laboratories then put these assets to productive use within and outside their labs toward the creation or extraction of value. I identify two models for producing value within academic science: a commodity-based model whereby laboratories mobilize their assets to produce results, which can be converted into publications for the accumulation of credibility capital, and a rentier model of accumulation whereby laboratories own valuable assets, which they rent out to others outside their lab against revenue. Following recent developments in Science and Technology Studies on value production in the bioeconomy, I argue that the concepts of asset and rent are essential analytical tools for getting to grips with the origins of value within academic science.

Taking into account how much modern medicine is a function of—and at the same time has a function in—science and technology, it is hardly surprising that both the approach of science studies and the idea of the social and cultural construction of health, disease, and bodies overlap, generally and specifically, in the realm of the novel field of MEDICINE STUDIES. The work already done in science and technology studies as well as in social studies of medicine, together with the rich (...) tradition of medical history and philosophy of medicine, may be considered a solid base and a good vantage point for further analysis. By exploring the shifts of knowledge production in medicine we may be able to see the driving forces behind the ongoing development of medicine and the associated transformation of its social functions in a new light. Based on historiographical reconstructions we may come up with a much more broadly contextualized understanding of the ways in which science, technology, medicine and society interact and in what regard their mutual interdependencies have been undergoing profound changes for a number of decades. By tracing the channels through which key concepts defining the relationship of medicine and its social context are negotiated, we may further explore how our notions of health, disease, and humanity are continuously morphing alongside the incessant transformations of medicine. This editorial explores the aims and scope of MEDICINE STUDIES as a truly transdisciplinary endeavor. (shrink)

The availability of new genetic testing technologies to identify individuals as at risk for a particular disease has inspired tremendous concern that individuals with gene mutations will soon be universally identified, for both insurance and employment purposes, as a genetic underclass. Scholarship in science and technology studies, however, suggests that understandings of genetic knowledge might be locally contingent, while research in comparative politics helps us understand how national context might play an important role in framing approaches to the regulation of (...) genetic information. What role does national context play in defining genetic risk and shaping approaches to the privacy of genetic information? Using data from interviews, document analysis, and ethnographic observation, the author follows debates among advocacy groups, insurers, and governments in the United States and Britain about the appropriate use of genetic information in insurance underwriting to understand how national context frames the definition of genetic risk as well as its regulation.

Biomedicine is today transforming the human condition, but how such transformation is to be understood is a matter of debate. I seek to contribute to the debate by focusing on recent developments within a relatively novel subfield of gerontology which is engaged in the bio-molecular and bio-demographic characterization of the processes associated with the development of the organism from birth to death. I argue that these developments aid understanding of the conceptual difficulties confronting neo-Darwinian biological thought and poststructuralist social theory (...) as one decentres the organism and the other the subject.

The authors study how an aerosol technology research group constructed a research agenda for itself and how its activity was changed in the process. The group's research agenda was heterogeneous, comprising several research areas in which the knowledge of aerosols was applied in different industrial contexts. The authors analyze the development of one of these areas, the research on the production of ultrafine particles from 1992 to 1997, employing the concept of mediated activity that has been developed in the cultural-historical (...) theory of activity. In the analysis, the activity is seen as the coevolution of the subject, the means, and the research object and the networks of collaboration with other activities. The applications developed in the collaborative networks significantly influence the identity and learning of the researchers, the construction of tools and instruments, and the selection of the phenomena to be studied.

This article traces the ubiquitous geopolitical metaphors used by researchers in the field of pregnancy-related microchimerism. In this research domain, immunologists and medical geneticists locate ‘non-self’ cells in women by marking Y chromosomes in cells derived from their sons. In the course of this research trajectory, experiments have yielded a number of surprises, beginning with the very presence of these cells in women decades after pregnancy. This finding confounded the expectations predicted by classical immunology, which posits the destruction of such (...) ‘foreign’ entities. Once they were known to be present, fetal cells were implicated in pathological and destructive activity. In a series of reorientations in which metaphor, theory and practice are entangled with matter, the characterization of these cells has shifted from invaders to insurgent foreigners to assimilated productive immigrants. The article reflects on this rich domain of material-semiotic practice to demonstrate that the case of fetomaternal cell trafficking contributes to a growing uneasiness with dominant ontologies of bodies as bounded, defended, pure collectives of homogeneous inhabitants.

This article explores how researchers in a scientific research lab co-operate with each other and value these co-operations, using a case study of a life sciences lab as an illustrative example. It explores how researchers within the lab co-operate in three main ways: through their ideas, methods and resources. A core contention of this article is that the values researchers attach to these different ways of co-operating can be assessed on two dimensions: goals and ways of understanding. The goals dimension (...) moves from group goals, manifested in the vision of the lab defined by its principal investigator, to the goals of individual researchers within the lab, often achieved through work on individual projects. Individual goals were more highly valued by researchers in this case study. The ways of understanding dimension moves from theory-based and theory-building research activities, to craft-based activities related to the research lab’s experiments. Theoretical ways of understanding are more highly valued by researchers in this case study. Combined, these two dimensions mean that researchers will value co-operations that support individual goals and theoretical ways of understanding more highly. Idea-based collaborations, individualistic and theoretical in nature, were the most highly valued. Collaborations based on resources, communal and craft-centered, were the least valued in this case study. (shrink)

This article combines the idea of the active interview with insights from science studies and suggests that some concepts from science studies, like boundary objects and trading zones, should be utilized to understand and facilitate the production and analysis of data in a transcultural interview. This is illustrated by examples from interviews that the author conducted with women computer science students and faculty in a university in Malaysia. The article argues that the understanding of, as well as the performance of (...) the transcultural interview might benefit from the highly pragmatic character of scientific investigations, focusing on using locally available resources to produce knowledge; and that this in turn may enhance our capacity to do feminist research.

Although scholarship in the social construction of technology has contributed much to illuminating technological development, most work using this theoretical approach is committed to an agency-centered approach. SCOT scholars have made only limited contributions to illustrating the influence of social structures. In this article, the authors argue for the importance of structural concepts to understanding technological development. They summarize the SCOT conceptual framework defined by Trevor Pinch and Wiebe Bijker and survey some of the methodological and explanatory difficulties that arise (...) with their approach. Then the authors present concepts from organizational sociology and political economy that illuminate structural influences in shaping phenomena of interest to SCOT scholars. These structural concepts can be applied to the study of the design, development, and transformation of technology. The authors conclude that the limited amount of scholarship on structural factors in the social shaping of technological development presents numerous opportunities for research. (shrink)

The dichotomy between the conceptual and the empirical is part of common sense, yet its organizing force also extends to intellectual life more generally, including the disciplinary life of science and technology studies. This article problematizes this dichotomy as it operates in contemporary STS discussions, arguing instead that the conceptual and the empirical form unstable hybrids. Beginning with a discussion of the “discontents” with which the dominant theory methods packages in STS are viewed, it is suggested that STS has entered (...) a phase resembling Kuhnian normal science. Based on a discussion of the making of cognitive dissonance theory, it is then argued conceptual–empirical mixtures are unavoidable in actual research practice. This situation can be taken as an encouragement for more sustained exploration of conceptual–empirical relations and their inventive potentials. Invoking Deleuze and Guattari’s notion of “continuous variation,” the article concludes that STS as a discipline is well served by promoting an ethos of empirical and conceptual experimentation.

In recent decades, academic science has increasingly been directed toward commercializable ends by neoliberal governments. In this article, I outline a concern that academic scientists have not been consulted about the transformation of science, but nevertheless, in some ways accept commercialization as the way things are done. I focus on the ways in which academic scientists attempt to exercise agency, albeit within the parameters of the neoliberal knowledge economy. In this economy, scientific inquiry has transformed to be focused more on (...) producing marketable products. In order to explore the parameters of scientists’ agency in the context of that transformation, I first elaborate on the idea of agency’s “parameters” and argue that the literature on commercialization lacks attention to how researchers’ agency is encouraged and discouraged in the context of academic research in the United States and Canada; second, I make a case for using the concept of hegemony to understand the ideas and practices of contemporary science; third, I propose a methodological direction that can attend to researchers’ agency in the contemporary context of the neoliberal knowledge economy.

Drawing on the idea of visions and the sociology of expectation, the article shows how different actors compete to have their preferred definitions of the term accepted (...) by the world at large.

Precision medicine is emerging as a scientific bandwagon within the contemporary biomedical sciences in the United States. PM brings together concepts and tools from genomics and bioinformatics to develop better diagnostics and therapies based on individualized information. Developing countries like China and Brazil have also begun pursuing PM projects, motivated by a desire to claim genomic sovereignty over its population. In spite of commonalities, institutional arrangements produced by the history of genomics research in China and Brazil are ushering PM along (...) different trajectories. In the Chinese case, we identify a strong state-backed push for PM combined with a dynamic network of international academic and private actors along the lines of networked technonationalism that has made large-scale, speculative PM projects possible. The Brazilian case is characterized by an institutional void at the federal level in which PM is driven by domestic academic actors in universities in the regional level, resulting in smaller scale, needs-driven PM projects. Through these cases, this paper shows how a scientific bandwagon adapts to national histories and institutions. Through this peripheral translation of the scientific bandwagon, the global infrastructure of biomedical knowledge has the potential to be transformed. (shrink)

The technique of nuclear transplantation – popularly known as cloning – has been integrated into several different histories of twentieth century biology. Historians and science scholars have situated nuclear transplantation within narratives of scientific practice, biotechnology, bioethics, biomedicine, and changing views of life. However, nuclear transplantation has never been the focus of analysis. In this article, I examine the development of nuclear transplantation techniques, focusing on the people, motivations, and institutions associated with the first successful nuclear transfer in metazoans in (...) 1952. The conflict between embryologists and geneticists over the mechanisms of differentiation motivated Robert Briggs to pursue nuclear transplantation experiments as a way to resolve the debate. Briggs worked at the Lankenau Hospital Research Institute, a research facility devoted to the study of cancer. The goal of understanding cancer would play a role in the development of the technique, and the story of nuclear transplantation sheds light on the role that biomedical contexts play in biological research in the second half of the twentieth century.

What is now familiarly referred to as the ‘embryonic stem (ES) cell’ is a recent biological category whose origins lie in research into benign and malignant teratomas carried out in the 1950s, 60s and 70s. In these studies, the question of the normal or pathological character of the ES cell was a matter of considerable debate and indeed the term ES cell was often used interchangeably with that of the embryonal carcinoma (EC) cell. This article argues that the indecisiveness of (...) the entity known as the ES cell—its refusal to commit to established demarcations between the normal and the pathological—continues to haunt the field of stem cell science. Exploring the prehistory of research into ES cells, early theories of cancer (in particular the embryonal theory expounded by Julius Cohnheim) and recent theoretical critiques of the somatic mutation theory, the article not only points to a shift in understandings of the normal and the pathological but asks under what conditions such shifts are able to take place.

This article focuses on a crucial development in genetic research that occurred in the 1990s: the identification of the first two of the genes responsible for hereditary breast and ovarian cancer. Issues addressed touch on the evolution of the subfield, its potential impact on cancer treatment, and industry involvement. The article follows the activities of the various research groups competing in the race to identify the genes and depicts the frequent conflicts between them. Data are derived chiefly from a bibliometric (...) database. The results show a diversity of research practices. Industrial researchers interacted within far more tightly knit networks than their counterparts working in public organizations. The patenting and commercial exploitation of results led to fierce battles, with one group capturing most of the benefits. (shrink)

This article explores the accounts of eugenics made by a small but important group of British scientists and clinicians working on the new genetics as applied to human health. These scientists and clinicians used special rhetorical strategies for distancing the new genetics from eugenics and to sustain their professional autonomy. They drew a number of boundaries or distinctions between eugenics and their own field, describing eugenics as politically distorted "bad science, " as being technically unfeasible, a feature of totalitarian regimes, (...) the abuse of neutral knowledge, and as the manipulation of the population's gene pool as opposed to diagnosing and treating individuals with genetic conditions. Their more sophisticated defense strategies invoked the importance of individual choice and the relationship between nature and nurture. The article highlights the ambiguities and difficulties in professionals' use of this rhetoric, drawing on historical and sociological analyses of eugenics, genetics, and medical science and technology more broadly.

Evo-Devo exhibits a plurality of scientific “cultures” of practice and theory. When are the cultures acting—individually or collectively—in ways that actually move research forward, empirically, theoretically, and ethically? When do they become imperialistic, in the sense of excluding and subordinating other cultures? This chapter identifies six cultures – three /styles/ (mathematical modeling, mechanism, and history) and three /paradigms/ (adaptationism, structuralism, and cladism). The key assumptions standing behind, under, or within each of these cultures are explored. Characterizing the internal structure of (...) the cultures is necessary for understanding how they collaborate or compete, and how they are fragmented or integrated, in the rich interdisciplinary /trading zone/ (Galison 1997) of Evo-Devo. Evo-Devo is an important example of how science can progress through a radical plurality of perspectives and cultures. (shrink)

The article reconsiders the nature and location of science in the development of genetic classification. Drawing on field studies of medical genetics, we explore how patient categorization is accomplished in between the clinic and laboratory. We focus on dysmorphology, a specialism concerned with complex syndromes that impair physical development. We show that dys-morphology is about more than fitting patients into prefixed diagnostic categories and that diagnostic process is marked by moments of uncertainty, ambiguity, and deferral. We describe how different forms (...) of evidence are brought into play and how patterns of physical features are identified as genetic or not. We suggest that clinical categorical work helps articulate the genetic as an emergent domain of medical classification and that moments of ambiguity and deferral create an imperative space that helps legitimate the need for more technoscience, and consequently, more clinical judgment with which to fix the genetic future.

I suggest that the transformation of an artifact from an introductory-type instrument into a viable, collectively used tool cannot be understood solely in terms of gradual adaptation of the technology and user environment, but also as a qualitatively broader integration process in which an expansion takes place. The case illustrated a constrained shift of an artifact from its first adopter, an individual pioneer user, to a more collective user in institutional medicine. The artifact, a neuromagnetometer instrument for brain research and (...) diagnostics, brings together physicists, neuroscientists, physicians as well as various practitioners from the medical imaging industry. I applied an activity-theoretical framework for analysing the adoption of the neuromagnetometer from the pioneer phase of implementation into the more established use. The case showed that the anticipated transformation of the artifact constituted a major challenge for the user organization and its practitioners. It is suggested that an expansion of the object into a shared object of implementation among the separate practitioner groups is indispensable.This expansion of the object involves for the practitioners to recognize both the different objects and requirements of the pioneer phase of the implementation and the new phase of introduction into medical practice. It is shown that this recognition does not, however, come as given, spontaneously born in the transition. The emerging new object may remain only partially shared if not made visible by deliberate effort among the practitioners. The expansion requires collective visualization of the work and reflective dialogue on it. Employing analytical tools, such as the activity-theoretical concepts used here, is one possible way of facilitating such an effort. (shrink)
