Gail Davies (Department of Geography, UCL) opened her presentation stating that her paper is about deviants, mutants, virgins and rogues. Davies emphasised, however, that these are not her terms, but are used by her respondents to talk about the animals in their care. She explained that these are people managing the range of genetically altered mice used in contemporary biomedical research. Further, Davies argued that the terms take us back to the monstrous bodily overspills of early taxonomy. However, she pointed out that the context here is twenty-first century biology. Therefore, Davies proposed that these terms emerge as animal caretakers and scientists seek to understand the challenge that spontaneous mutations in laboratory mice present to their use as experimental objects. Unexpected happenings in the mouse house either herald a useful new strain of research animal, or they are culled. Gail Davies stated that she is interested in where and when these different outcomes occur – the difference difference makes as it were. Being a geographer, she read this through the spatiality of these experimental forms, using site as the basis from which to explore whether these moments of biological emergence are able to articulate new potential, or remain excessive to the demands of control in experimental systems.
