In this introduction to the special section ‘Biocircularities: New Formations of Embodied Time’, we introduce the concept of ‘biocircularity’. Drawing on case studies from Senegal, Australia and the United States, we argue that (bio)circularities provides a new tool to understand transformations of embodiment and embodied time in response to rapid technoscientific, social and environmental change. We situate the potential of biocircularity by distinguishing the approach from cycles and ‘looping’. We lay out why we think biocircularity is an important concept now, (...) when we stand on the brink of ecological crisis and reproductive futures appear deeply precarious and uncertain. Biocircularity, we argue, offers new ways of understanding how people live out embodiment and understand biological time. The concept offers new possibilities for theorising and realising scientific practice and public health interventions. (shrink)

In the middle of the twentieth century, physiologists interested in human biological rhythms undertook a series of field experiments in natural spaces that they believed could closely approximate conditions of biological timelessness. With the field of rhythms research was still largely on the fringes of the life sciences, natural spaces seemed to offer unique research opportunities beyond what was available to physiologists in laboratory spaces. In particular, subterranean caves and the High Arctic became archetypal ‘natural laboratories’ for the study of (...) human circadian (daily) rhythms. This paper is explores the field experiments which occurred in these ‘timeless spaces’. It considers how scientists understood these natural spaces as suitably ‘timeless’ for studying circadian rhythms and what their experimental practices can tell us about contemporary physiological notions of biological time, especially its relationship to ‘environmentality’ (Formosinho et al. in Stud History Philos Sci 91:148–158, 2022). In so doing, this paper adds to a growing literature on the interrelationship of field sites by demonstrating the ways that caves and the Arctic were connected by rhythms scientists. Finally, it will explore how the use of these particular spaces were not just scientific but also political – leveraging growing Cold War anxieties about nuclear fallout and the space race to bring greater prestige and funding to the study of circadian rhythms in its early years.

In 1817, the German botanist Ludolph Christian Treviranus (1779–1864), while working on cytoplasmic streaming, exclaimed “What a matter for new observations and what an expectation for a more profo...
