Abstract
What can’t freezing hold still? This article surveys the history of substances used to protect cells and organisms from freezing damage, known as cryoprotectants. Dimethyl sulfoxide (DMSO) has since 1959 been the most widely used of these agents in cryopreservation. Here, its evolution from pulp and paper waste byproduct to wonder drug to all-but-invisible routine element of freezing protocols is used to trace the direct arc from protection to toxicity in theories of how and why cryoprotectants work, from the 1960s to today. The power of these agents to simultaneously protect and degrade is shown to reside in manipulation of chemical time via hydrogen bonding and electron exchange, thereby reframing freezing as a highly active and transformational process. Countering long-held assumptions about cryopreservation as an operation of stasis after which the thawed entity is the same as it was before, this article details recent demonstrations of effects of cryoprotectant exposure that are nonlethal but nonetheless profoundly impactful within scientific and therapeutic practices that depend on freezing infrastructures. Understanding the operationalization of chemical time in the case of cryoprotectants is broadly relevant to other modern technologies dedicated to shifting how material things exist and persist in human historical time.
期刊介绍：
BioSocieties is committed to the scholarly exploration of the crucial social, ethical and policy implications of developments in the life sciences and biomedicine. These developments are increasing our ability to control our own biology; enabling us to create novel life forms; changing our ideas of ‘normality’ and ‘abnormality’; transforming our understanding of personal identity, family relations, ancestry and ‘race’; altering our social and personal expectations and responsibilities; reshaping global economic opportunities and inequalities; creating new global security challenges; and generating new social, ethical, legal and regulatory dilemmas. To address these dilemmas requires us to break out from narrow disciplinary boundaries within the social sciences and humanities, and between these disciplines and the natural sciences, and to develop new ways of thinking about the relations between biology and sociality and between the life sciences and society.
BioSocieties provides a crucial forum where the most rigorous social research and critical analysis of these issues can intersect with the work of leading scientists, social researchers, clinicians, regulators and other stakeholders. BioSocieties defines the key intellectual issues at the science-society interface, and offers pathways to the resolution of the critical local, national and global socio-political challenges that arise from scientific and biomedical advances.
As the first journal of its kind, BioSocieties publishes scholarship across the social science disciplines, and represents a lively and balanced array of perspectives on controversial issues. In its inaugural year BioSocieties demonstrated the constructive potential of interdisciplinary dialogue and debate across the social and natural sciences. We are becoming the journal of choice not only for social scientists, but also for life scientists interested in the larger social, ethical and policy implications of their work. The journal is international in scope, spanning research and developments in all corners of the globe.
BioSocieties is published quarterly, with occasional themed issues that highlight some of the critical questions and problematics of modern biotechnologies. Articles, response pieces, review essays, and self-standing editorial pieces by social and life scientists form a regular part of the journal.
