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.

Drugged bodies are commonly depicted as passive, suffering and abject, which makes it hard for them to be known in other ways. Wanting to get closer to these alternative bodies and their resourcefulness for living, I turned to body-mapping as an inventive method for telling different kinds of drug-using stories. Drawing on a research project with people who inject heroin and crack cocaine in London, UK, I employed body-mapping as a way of studying drugged bodies in their relation to others, human and non-human, in the injecting event. I invited participants to draw their bodies in describing these otherwise hard-to-articulate experiences. Following Donna Haraway, I conceptualise body-mapping as a more-than-human mode of storytelling where different kinds of bodies can be known. Here, I look at three such bodies - sensing-bodies, temporal-bodies and environment-bodies - and argue that it is through being able to respond to such bodies that more hospitable ways of living with drugs can become possible.

Breath is invisible and yet ever present and vital for living beings. The concept of invisibility in relation to breath operates in concrete and metaphorical ways to extend ideas about breath and breathlessness across disciplines, in clinical spaces and in life experience. Using a critical medical humanities approach, I demonstrate that the poverty of narrative accounts and language for breath outside the health context have had a crucial influence enabling clinically mediated interpretations and accounts to dominate. These third-person accounts are important in the articulation of the 'lived body', but I balance this with a consideration of the subjective sensation of interoception, which has important implications for the visibility of breathlessness in both clinical and lay contexts. This article illustrates the rich potential of the subjects of breath and breathlessness within body studies and this special issue is a key step in making breath such an emergent topic.

Breath, the ephemeral materialization of air at the interface of body and world, engages with and alters the quality of both. As a process of inhalation and exhalation that signals its physiological universality, breath is an invisible prerequisite for life, an automated and functional necessity. Yet it is more than simply a reflexive action and can at times be controlled or manipulated. It can also affect or be affected by experiences, environments and relationships. In this essay, like the contributors to the special issue it prefaces, we aim to address the lacuna that exists in the examination of the meanings and embodiment of breath as a central theme in the humanitics and social sciences. Interdisciplinary perspectives that explore breath as a multifaceted phenomenon, both intrinsically shared and contextually distinct, open new directions in the field of breath and body studies.

This article sets the stage for a genealogy of the postgenomic body. It starts with the current transformative views of epigenetics and microbiomics to offer a more pluralistic history in which the ethical problem of how to live with a permeable body - that is plasticity as a form of life - is pervasive in traditions pre-dating and coexisting with modern biomedicine (particularly humoralism in its several ramifications). To challenge universalizing narratives, I draw on genealogical method to illuminate the unequal distribution of plasticity across gender and ethnic groups. Finally, after analysing postgenomics as a different thought-style to genomics, I outline some of its implications for notions of plasticity. I argue that postgenomic plasticity is neither a modernistic plasticity of instrumental control of the body nor a postmodernist celebration of endless potentialities. It is instead closer to an alter-modernistic view that disrupts clear boundaries between openness and determination, individual and community.

Beginning in the 1940s, mass production of antibiotics involved the industrial-scale growth of microorganisms to harvest their metabolic products. Unfortunately, the use of antibiotics selects for resistance at answering scale. The turn to the study of antibiotic resistance in microbiology and medicine is examined, focusing on the realization that individual therapies targeted at single pathogens in individual bodies are environmental events affecting bacterial evolution far beyond bodies. In turning to biological manifestations of antibiotic use, sciences fathom material outcomes of their own previous concepts. Archival work with stored soil and clinical samples produces a record described here as 'the biology of history': the physical registration of human history in bacterial life. This account thus foregrounds the importance of understanding both the materiality of history and the historicity of matter in theories and concepts of life today.

The growing abundance of medical technologies has led to laments over doctors' sensory de-skilling, technologies viewed as replacing diagnosis based on sensory acumen. The technique of percussion has become emblematic of the kinds of skills considered lost. While disappearing from wards, percussion is still taught in medical schools. By ethnographically following how percussion is taught to and learned by students, this article considers the kinds of bodies configured through this multisensory practice. I suggest that three kinds of bodies arise: skilled bodies; affected bodies; and resonating bodies. As these bodies are crafted, I argue that boundaries between bodies of novices and bodies they learn from blur. Attending to an overlooked dimension of bodily configurations in medicine, self-perception, I show that learning percussion functions not only to perpetuate diagnostic craft skills but also as a way of knowing of, and through, the resource always at hand; one's own living breathing body.

In 2003 the UK National Blood Service introduced a policy of 'male donor preference' which involved women's plasma being discarded following blood collection. The policy was based on the view that data relating to the incidence of Transfusion-Related Acute Lung Injury (TRALI) was linked to transfusion with women's plasma. While appearing to treat female donors as equal to male donors, exclusion criteria operate after donation at the stage of processing blood, thus perpetuating myths of universality even though only certain 'extractions' from women are retained for use in transfusion. Many women in the UK receive a plasma-derived product called Anti-D immunoglobulin which is manufactured from pooled male plasma. This article examines ways in which gender has significance for understanding blood relations, and how the blood economy is gendered. In our study of relations between blood donors and recipients, we explore how gendered bodies are produced through the discursive and material practices within blood services. We examine both how donation policies and the manufacturing and use of blood products produces gendered blood relations.
