This essay considers how scholarly approaches to the development of molecular biology have too often narrowed the historical aperture to genes, overlooking the ways in which other objects and processes contributed to the molecularization of life. From structural and dynamic studies of biomolecules to cellular membranes and organelles to metabolism and nutrition, new work by historians, philosophers, and STS scholars of the life sciences has revitalized older issues, such as the relationship of life to matter, or of physicochemical inquiries to (...) biology. This scholarship points to a novel molecular vista that opens up a pluralist view of molecularizations in the twentieth century and considers their relevance to current science. (shrink)

The role of a journal like HPLS during the novel coronavirus pandemic should serve as a means for scholars in different fields and professions to consider historically and critically what is happening as it unfolds. Surely it cannot tackle all the possible issues related to the pandemic, in particular to the COVID-19 pandemic, but it does have a responsibility to foster the best possible dialogue about the various issues related to the history and philosophy of the life sciences, and thus (...) to solicit contributions from potential authors working in different parts of the world and belonging to different cultural traditions. Only a real plurality of perspectives should allow for a better, large-scale comprehension of what the COVID-19 pandemic is. (shrink)

The essays in this Focus section expand the notion of writing insect histories of science by attending to matters of space and scale, ecological relationships, and institutional silences. They magnify diverse understandings about how the worlds of insects are noticed and understood by humans, what has historically counted as “insect,” and who narrates histories (of science). In doing so, the collection offers methodological suggestions for studying tiny animals in history that broaden the scope of often overlapping material, cultural, linguistic, political, (...) ethical, economic, and biological domains. It is precisely this magnified attention that foregrounds the domains’ interdependence and is necessary to make sense of additional bearers or forms of agency. (shrink)

The binary categories of harm and benefit have often shaped how historians frame discussions of insects. Scientists also leverage the binary framing of insects as tools and targets to carry out their work, especially in the development of biological technologies for pest control. This essay emphasizes how binaries function in scientific practice. Two case studies spanning from the twentieth century to the recent past illustrate the shift away from chemicals in pest management and, in doing so, show the instability of (...) binary categories over the longue durée. Noticing “ambivalent insects” affords a way to widen narrative options and identify new opportunities for investigating insect histories. (shrink)

Japanese agricultural scientist Toyama Kametaro’s report about the Mendelian inheritance of silkworm cocoon color in Studies on the Hybridology of Insects spurred changes in Japanese silk production and thrust Toyama and his work into a scholarly exchange with American entomologist Vernon Kellogg. Toyama’s work, based on research conducted in Japan and Siam, came under international scrutiny at a time when analyses of inheritance flourished after the “rediscovery” of Mendel’s laws of heredity in 1900. The hybrid silkworm studies in Asia attracted (...) the attention of Kellogg, who was concerned with how experimental biology would be used to study the causes of natural selection. He challenged Toyama’s conclusions that Mendelism alone could explain the inheritance patterns of silkworm characters such as cocoon color because they had been subject to hundreds of years of artificial selection, or breeding. This examination of the intersection of Japanese sericulture and American entomology probes how practical differences in scientific interests, societal responsibilities, and silkworm materiality were negotiated throughout the processes of legitimating Mendelian genetics on opposite sides of the Pacific. The ways in which Toyama and Kellogg assigned importance to certain silkworm properties show how conflicting intellectual orientations arose in studies of the same organism. Contestation about Mendelism took place not just on a theoretical level, but the debate was fashioned through each scientist’s rationale about the categorization of silkworm breeds and races and what counted as “natural.” This further mediated the acceptability of the silkworm not as an experimental organism, but as an appropriately “natural” insect with which to demonstrate laws of inheritance. All these shed light on the challenges that came along with the use of agricultural animals to convincingly articulate new biological principles. (shrink)
