Preparative and analytical methods developed by separation scientists have played an important role in the history of molecular biology. One such early method is gel electrophoresis, a technique that uses various types of gel as its supporting medium to separate charged molecules based on size and other properties. Historians of science, however, have only recently begun to pay closer attention to this material epistemological dimension of biomolecular science. This paper substantiates the historiographical thread that explores the relationship between modern laboratory (...) practice and the production of scientific knowledge. It traces the historical development of gel electrophoresis from the mid-1940s to the mid-1960s, with careful attention to the interplay between technical developments and disciplinary shifts, especially the rise of molecular biology in this time-frame. Claiming that the early 1950s marked a decisive shift in the evolution of electrophoretic methods from moving boundary to zone electrophoresis, I reconstruct various trajectories in which scientists such as Oliver Smithies sought out the most desirable solid supporting medium for electrophoretic instrumentation. Biomolecular knowledge, I argue, emerged in part from this process of seeking the most appropriate supporting medium that allowed for discrete molecular separation and visualization. The early 1950s, therefore, marked not only an important turning point in the history of separation science, but also a transformative moment in the history of the life sciences as the growth of molecular biology depended in part on the epistemological access to the molecular realm available through these evolving technologies.

This study considers the role of epistemic turning points in the historiography of sexuality. Disentangling the historical complexity of scientia sexualis, I argue that the late 19th century and the mid-20th century constitute two critical epistemic junctures in the genealogy of sexual liberation, as the notion of free love slowly gave way to the idea of sexual freedom in modern western society. I also explore the value of the Foucauldian approach for the study of the history of sexuality in non-western (...) contexts. Drawing on examples from Republican China (1912—49), I propose that the Foucauldian insight concerning the emergence of a ‘homosexual identity’ in the West can serve as a useful guide for thinking about similar issues in the history of sexuality and the historical epistemology of sexology in modern East Asia.

Historians and philosophers of science have furnished a wide array of theoretical-historiographical terms to emphasize the discontinuities among different systems of knowledge. Some of the most famous include Thomas Kuhn’s “paradigm”, Michel Foucault’s “episteme”, and the notion of “styles of reasoning” more recently developed by Ian Hacking and Arnold Davidson. This paper takes up this theoretical-historiographical thread by assessing the values and limitations of the notion of “style” for the historical and philosophical study of science. Specifically, reflecting on various methodological (...) and theoretical concerns prompted by sexuality, translation, and East Asian studies, this paper argues that the heretofore ways in which historians and philosophers of science have used the notion of “style” are severely restricted in terms of its mere applicability to the intellectual history of Western science. The particular example of the translation of “homosexuality” into Chinese during the May Fourth era reveals that the notion of “style” has the potential of carrying a much more dynamic conceptual weight, as when used in “styles of argumentation”. The paper also engages briefly with the historiography of scientific “national styles” and ends with some concluding remarks on the limitations of “social histories from below” and the under appreciated importance of “epistemological histories of possibilities”.

This article examines the development of koro’s epistemic status as a paradigm for understanding culture-specific disorders in modern psychiatry. Koro entered the DSM-IV as a culture-bound syndrome in 1994, and it refers to a person’s overpowering belief that his genitalia is retracting and even disappearing. I focus in particular on mental health professionals’ competing views of koro in the 1960s—as an object of psychoanalysis, a Chinese disease, and a condition predisposed by culture. At that critical juncture, transcultural psychiatrists based outside (...) of continental China—namely, Taiwan, Hong Kong, and Singapore—appropriated ideas from traditional Chinese culture to consolidate the clinical diagnosis of koro as culture-bound. This new global meaning of koro was made possible by a cohort of medical experts who encountered the phenomenon and its sufferers in Sinophone communities, but placed their contributions within the broader contours of the global reach of Anglophone psychiatric science.
