RESUMO

In this paper, we investigate the ways in which a group of scientists in Edinburgh worked across mice and sheep during the last quarter of the twentieth century. With this local episode, we show the utility of an interspecies perspective to investigate recent historical transformations in the life sciences. We argue that the emergence of animal biotechnology was the result of interactions between neoliberal policymakers, science administrators, molecular biologists, agricultural breeders, and the laboratory and farm organisms with which they worked. During the early 1980s, all these actors believed that the exportation of genetic engineering techniques from mice to farm animals would lead to more effective breeding programmes in the agricultural sciences. However, the circulation of people, money, expertise and infrastructures that the experiments required, as well as the practical constraints of working with mice and sheep, resisted a simple scaling-up from one organism to the other. This displaced the goals of the Edinburgh scientists from the production of transgenic sheep to stem cell research and human regenerative medicine. We account for this unexpected shift by looking at the interplay between science policy and its implementation via collective action and bench work across different organisms. The emergence of animal biotechnology in Edinburgh also provides historiographical insights on the birth of Dolly the sheep and, more generally, on the interactions between the molecular and the reproductive sciences at the fall of the twentieth century.

RESUMO

In this paper, I propose a strategy for navigating newly available archives in the study of late-twentieth century genomics. I demonstrate that the alleged 'explosion of data' characteristic of genomics-and of contemporary science in general-is not a new problem and that historians of earlier periods have dealt with information overload by relying on the 'perspective of time': the filtering effect the passage of time naturally exerts on both sources and memories. I argue that this reliance on the selective capacity of time results in inheriting archives curated by others and, consequently, poses the risk of reifying ahistorical scientific discourses. Through a preliminary examination of archives documenting early attempts at mapping and sequencing the human genome, I propose an alternative approach, in which historians proactively problematize and improve available sources. This approach provides historians with a voice in the socio-political management of scientific heritage and advances methodological innovations in the use of oral histories. It also provides a narrative framework in which to address big science initiatives by following second order administrators, rather than individual scientists. The new genomic archives thus represent an opportunity for historians to take an active role in current debates concerning 'big data' and critically embed the humanities in pressing global problems.

RESUMO

This paper addresses the 1996 cloning of Dolly the sheep, locating it within a long-standing tradition of animal breeding research in Edinburgh. Far from being an end in itself, the cell-nuclear transfer experiment from which Dolly was born should be seen as a step in an investigative pathway that sought the production of medically relevant transgenic animals. By historicising Dolly, I illustrate how the birth of this sheep captures a dramatic redefinition of the life sciences, when in the 1970s and 1980s the rise of neo-liberal governments and the emergence of the biotechnology market pushed research institutions to show tangible applications of their work. Through this broader interpretative framework, the Dolly story emerges as a case study of the deep transformations of agricultural experimentation during the last third of the twentieth century. The reorganisation of laboratory practice, human resources and institutional settings required by the production of transgenic animals had unanticipated consequences. One of these unanticipated effects was that the boundaries between animal and human health became blurred. As a result of this, new professional spaces emerged and the identity of Dolly the sheep was reconfigured, from an instrument for livestock improvement in the farm to a more universal symbol of the new cloning age.

RESUMO

Historical epistemology, according to the historian of science Hans-Jörg Rheinberger, is a space through which "to take experimental laboratory work into the realm of philosophy". This key concept, together with the crucial events and challenges of his career, were discussed in a public conversation which took place on the occasion of Rheinberger's retirement. By making sense of natural phenomena in the laboratory, the act of experimenting shapes the object; it is this shaping which became the core of Rheinberger's own research across biology and philosophy into history. For his intellectual agenda, a history of the life sciences so constructed became "epistemologically demanding".

RESUMO

This paper argues that the history of the computer, of the practice of computation and of the notions of 'data' and 'programme' are essential for a critical account of the emergence and implications of data-driven research. In order to show this, I focus on the transition that the investigations on the worm C. elegans experienced in the Laboratory of Molecular Biology of Cambridge (UK). Throughout the 1980s, this research programme evolved from a study of the genetic basis of the worm's development and behaviour to a DNA mapping and sequencing initiative. By examining the changing computing technologies which were used at the Laboratory, I demonstrate that by the time of this transition researchers shifted from modelling the worm's genetic programme on a mainframe apparatus to writing minicomputer programs aimed at providing map and sequence data which was then circulated to other groups working on the genetics of C. elegans. The shift in the worm research should thus not be simply explained in the application of computers which transformed the project from hypothesis-driven to a data-intensive endeavour. The key factor was rather a historically specific technology-in-house and easy programmable minicomputers-which redefined the way of achieving the project's long-standing goal, leading the genetic programme to co-evolve with the practices of data production and distribution.

RESUMO

This paper explores the introduction of professional systems engineers and information management practices into the first centralized DNA sequence database, developed at the European Molecular Biology Laboratory (EMBL) during the 1980s. In so doing, it complements the literature on the emergence of an information discourse after World War II and its subsequent influence in biological research. By the careers of the database creators and the computer algorithms they designed, analyzing, from the mid-1960s onwards information in biology gradually shifted from a pervasive metaphor to be embodied in practices and professionals such as those incorporated at the EMBL. I then investigate the reception of these database professionals by the EMBL biological staff, which evolved from initial disregard to necessary collaboration as the relationship between DNA, genes, and proteins turned out to be more complex than expected. The trajectories of the database professionals at the EMBL suggest that the initial subject matter of the historiography of genomics should be the long-standing practices that emerged after World War II and to a large extent originated outside biomedicine and academia. Only after addressing these practices, historians may turn to their further disciplinary assemblage in fields such as bioinformatics or biotechnology.

RESUMO

This paper explores the different identities adopted by connective tissue research at the University of Manchester during the second half of the 20th century. By looking at the long-term redefinition of a research programme, it sheds new light on the interactions between different and conflicting levels in the study of biomedicine, such as the local and the global, or the medical and the biological. It also addresses the gap in the literature between the first biomedical complexes after World War II and the emergence of biotechnology. Connective tissue research in Manchester emerged as a field focused on new treatments for rheumatic diseases. During the 1950s and 60s, it absorbed a number of laboratory techniques from biology, namely cell culture and electron microscopy. The transformations in scientific policy during the late 70s and the migration of Manchester researchers to the US led them to adopt recombinant DNA methods, which were borrowed from human genetics. This resulted in the emergence of cell matrix biology, a new field which had one of its reference centres in Manchester. The Manchester story shows the potential of detailed and chronologically wide local studies of patterns of work to understand the mechanisms by which new biomedical tools and institutions interact with long-standing problems and existing affiliations.

RESUMO

Fred Sanger, the inventor of the first protein, RNA and DNA sequencing methods, has traditionally been seen as a technical scientist, engaged in laboratory bench work and not interested at all in intellectual debates in biology. In his autobiography and commentaries by fellow researchers, he is portrayed as having a trajectory exclusively dependent on technological progress. The scarce historical scholarship on Sanger partially challenges these accounts by highlighting the importance of professional contacts, institutional and disciplinary moves in his career, spanning from 1940 to 1983. This paper will complement such literature by focusing, for the first time, on the transition of Sanger's sequencing strategies from degrading to copying the target molecule, which occurred in the late 1960s as he was shifting from protein and RNA to DNA sequencing, shortly after his move from the Department of Biochemistry to the Laboratory of Molecular Biology, both based in Cambridge (U.K.). Through a reinterpretation of Sanger's papers and retrospective accounts and a pioneering investigation of his laboratory notebooks, I will claim that sequencing shifted from the working procedures of organic chemistry to those of the emergent molecular biology. I will also argue that sequencing deserves a history in its own right as a practice and not as a technique subordinated to the development of molecular biology or genomics. My proposed history of sequencing leads to a reappraisal of current STS debates on bioinformatics, biotechnology and biomedicine.

RESUMO

In 1983, after devoting some eight years of his life to the description of how a nematode worm develops from an embryo into an adult, molecular biologist John Sulston embarked on a remarkably different project: he decided to map the worm's genome. Sulston's impulsive desire to characterise this creature's DNA from start to finish offers only a partial explanation for this transition. Instead, a close examination of the wider social context for this 'moment' in molecular biology gives a more rewarding explanation of Sulston's intellectual leap. This reveals a world in which biotechnology gradually adapted to and integrated into an 'information society' increasingly dependent on the creation, distribution and manipulation of information. The application of computing to DNA during the first half of the 1980s was crucial for this integration, fostering the emergence of genomics and ultimately the Human Genome Project.
