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)

“Historicity” describes the human condition during one’s life course, marked by contingency and freedom, temporality and finitude. The concept also occurs in evolutionary biology, social sciences and psychology, highlighting history and context. Hannah Arendt situates the capacity for new beginnings at the essence of human beings (natality), allowing for new generations. Transhumanist narratives are shown as foreign to the concept of historicity due to a view of human nature, the load of accumulated past, and directed evolution. Finally, the “back to (...) dust” motif is related to finitude, suggesting that new technologies may move us away from humanness. (shrink)

In this article, I materially situate air pollution exposure as a topic of social and political inquiry by paying attention to the increasing specificity of spaces and sites of exposure in air pollution and health research. Evidence of the unevenness of exposure and differential health effects of air pollution have led to a proliferation of studies on the risks different environments pose to bodies. There are increasingly different airs in air pollution science. In this research, bodies are often relegated to (...) passive objects, exposed according to the environments they move between. Yet exposure implies a blurring of bodies and environments which also challenges the idea of a discrete body that is distinguishable from its material context. By studying the process of modelling indoor air pollution, I highlight how air pollution, buildings and bodies are co-implicated with one another in ways that demand new ways of materialising human exposure in science.

Social theory has paid little attention to air, despite its centrality to bodily existence and air pollution being named the world’s biggest public health crisis. Where attention to air is found, the body is largely absent. On the other hand, conceptualizing the body without life-sustaining breath fails to highlight breathing as the ongoing metabolic bodily act in which the materiality of human and more-than-human intermingle and transmute one another. Political ecology studies how unequal power structures and knowledge production reproduce human–environment (...) relations, including a nascent focus on the body and air – but as separate issues. This article argues that a political ecology of air would productively fuse with a political ecology of the body to bring the visceral realm into intersectional analysis of air’s contemporary materialities. A feminist political ecology situates explicitly air-and-breathing-bodies, their intimately posthuman, relational, elemental and corpomaterial intra-action, at the heart of such analysis. (shrink)

Some Indigenous Australians have embraced developmental origins of health and disease (DOHaD) and epigenetic discourses to highlight the legacies of slow violence in a settler colonial context. Despite important differences between Indigenous and scientific knowledges, some Indigenous scholars are positioning DOHaD and epigenetics as a resource to benefit their communities. This article argues that time plays a crucial role of brokering disparate knowledge spaces in Indigenous discourses of postgenomics, with both Indigenous cosmological frames and DOHaD/epigenetics centring a circular temporal model. (...) Drawing on interview data with scientists who work in Indigenous health, and broader ethnographic work in Indigenous Australian contexts where epigenetics is deployed, this article explores how different circularities of space and time become entangled to co-produce narratives of historical trauma. We use the concept of biocircularity to understand the complex ways that Indigenous and postgenomic temporalities are separated and connected, circling each other to produce a postcolonial articulation of postgenomics as a model of collective embodiment and distributed responsibility.

This article builds on feminist scholarship on new biologies and the body to describe the temporal politics of epigenetic research related to the human placenta. Drawing on interviews with scientists and observations at conferences and in laboratories, we argue that epigenetic research simultaneously positions placenta tissue as a way back into maternal and fetal bodies following birth, as a lens onto children’s future well-being, and as a bankable resource for ongoing research. Our findings reflect how developmental models of health have (...) helped recast the placenta as an agential organ that is uniquely responsive to environments during pregnancy and capable of embodying biological evidence about the effects of in utero experiences after birth. We develop the concept of ‘recursive embodiment’ to describe how placenta epigenetics is reimagining relationships between bodies and environments across developmental, epigenetic, and generational time, and the impacts this has for experiences of pregnancy and responsibilities related to children’s health.

This article explores the metabolic lives of whey powder, the most popular form of protein supplement in what has become a multibillion-dollar industry during the past two decades. Faced with the slippery and elusive properties latent to this multiplicitous substance, our approach is to follow whey powder from its mid-20th century emergence as a noxious byproduct of industrial dairy production, through the human and animal bodies unevenly tasked with its processing, and out into waterways, where its nitrogen density rematerializes as (...) a pollutant. We show how whey powder emerged as a solution to the environmental damage posed by whey pollution, how such damage is an effect of the systematic overproduction endemic to agrofood industries and how whey’s toxicity persists through processes of metabolism and consumption, despite attempts to process and profit from its vital capacities. Throughout, we argue that whey exemplifies ecological embodiment, understood as the co-constitutive relations between bodily matter and ecological life, and their entanglement with processes of commodification.

While unicellular microbes such as phytoplankton (marine algae) have long been considered immortal unless eaten by predators, recent research suggests that under specific conditions entire populations of phytoplankton actively kill themselves; their assumed atemporality is being revised as marine ecologists recognize phytoplankton’s important role in the global carbon cycle. Drawing on empirical research into programmed cell death in marine microbes, this article explores how, in their study of microbial death, scientists change not only our understanding of microbial temporality, but also (...) reconstruct the relationship between life and death, biological individuality and assumptions about a natural teleology associated with bounded biological systems and genetic programmes. Reading this research together with a Derridean deconstruction of the limit between human and other animals with respect to death, this article explores how the deconstruction of individuality from within biology may suggest alternatives to our anthropocentric notion of time and embodiment.

Over the last few decades feminists, science and technology studies scholars and others have grappled with how to take materiality into account in understanding social practices, subjectivity and events. One key area for these debates has been drug use and addiction. At the same time, neuroscientific accounts of drug use and addiction have also arisen. This development has attracted criticism as simplistically reinstating material determinism. In this article we draw on 80 interviews with health professionals directly involved in drug-related public (...) policy and service provision in three countries to identify the main ways the neuroscience of addiction (and thus the agency of the brain) is understood. We analyse these understandings using contemporary posthumanist theory to develop new options for conceptualizing matter in public responses to addiction. We close by calling for a new approach to addiction and the brain based on a process model of materiality and public debate. (shrink)
