The Cosmology of Evidence: Suffering, Science, and Biological Witness After Three Mile Island.

The 1979 partial nuclear reactor meltdown at Three Mile Island was simultaneously hyper-visible and hidden from public view. It was the subject of non-stop media attention, but its causes and consequences required expert explanation. No fire or explosion marked the moment when insensible radionuclides escaped the facility. Yet, residents recalled a variety of troubling sights, sounds, odors, tastes, and sensations. Public distrust percolated in the interstices between government assertions that little radiation had escaped the facility and residents' sense memories of the incident. This article traces intertwined networks of activists from Japan and Pennsylvania as they mobilized legally, politically, and scientifically to develop evidence about the offsite effects of Three Mile Island. Exploring the distinct cosmology of evidence that activists marshaled, the article shows how they placed the messy, contingent, dynamic living world at the center of inquiries about the meltdown's consequences. Activists developed new practices of biological witness that reconfigured the interplay between scientific, legal, and moral authority, while concurrently reformulating sufferers' subjectivities and notions of scientific objectivity. In the process, they suggested that environmental justice entailed epistemic justice. Their cosmology of evidence served as an argument and a material proof that the beloved but suffering living world, and the sciences used to understand it, could and should frame the governance of industrial society's invisible harms.

Screening Out Controversy: Human Genetics, Emerging Techniques of Diagnosis, and the Origins of the Social Issues Committee of the American Society of Human Genetics, 1964-1973.

In the years following World War II, and increasingly during the 1960s and 1970s, professional scientific societies developed internal sub-committees to address the social implications of their scientific expertise (Moore, Disrupting Science: Social Movements, American Scientists, and the Politics of the Military, 1945-1975. Princeton: Princeton University Press, 2008). This article explores the early years of one such committee, the American Society of Human Genetics' "Social Issues Committee," founded in 1967. Although the committee's name might suggest it was founded to increase the ASHG's public and policy engagement, exploration of the committee's early years reveals a more complicated reality. Affronted by legislators' recent unwillingness to seek the expert advice of human geneticists before adopting widespread neonatal screening programs for phenylketonuria (PKU), and feeling pressed to establish their relevance in an increasingly resource-scarce funding environment, committee members sought to increase the discipline's expert authority. Painfully aware of controversy over abortion rights and haunted by the taint of the discipline's eugenic past, however, the committee proceeded with great caution. Seeking to harness interest in and assert professional control over emerging techniques of genetic diagnosis, the committee strove to protect the society's image by relegating ethical and policy questions about their use to the individual consciences of member scientists. It was not until 1973, after the committee's modest success in organizing support for a retrospective public health study of PKU screening and following the legalization of abortion on demand, that the committee decided to take a more publicly engaged stance.
