Metaphors in search of a target: the curious case of epigenetics

Analysing bio-art’s epistemic landscape: from metaphoric to post-metaphoric structure

Since its emergence, bio-art has developed numerous metaphors central to the transfer of concepts of modern biology, genetics, and genomics to the public domain that reveal several cultural, ethical, and social variations in their related themes. This article assumes that a general typology of metaphors developed by practices related to bio-art can be categorised into two categories: pictorial and operational metaphors. Through these, information regarding several biological issues is transferred to the public arena. Based on the analysis, this article attempts to answer the following questions: How does bio-art develop metaphors to advance epistemic and discursive agendas that constitute public understanding of a set of deeply problematic assumptions regarding how today’s biology operates? Under the influence of today’s synthetic biology, could bio-media operationally reframe these epistemic agendas by reframing complex and multi-layered metaphors towards post-metaphoric structures? Finally, what are the scientific, cultural, and social implications of reframing?

Gene drive communication: exploring experts' lived experience of metaphor use

Metaphors have been crucial in making genetics and genomics public, from the code and the book of life to genetic scissors and gene surgery. A new field is emerging called "gene drive" - a range of controversial technologies that can potentially be used for the eradication or conservation of animal species. At the same time, metaphors are emerging to talk about the promises and dangers of "gene drive". In this article we use thematic analysis to examine thirty interviews with gene drive science and communication experts, and stakeholders, focusing on how they talk about their lived experience of metaphor use in the context of gene drive communication, including their struggle to remember salient metaphors and their reflections on which metaphors to use and which to avoid. We discuss the significance of our findings for research and practice of responsible science communication.

Metaphors and why these are important in all aspects of genetic counseling

Metaphors appear simple but are fundamental schemata allowing expression and processing of complex emotions and information. They are so embedded in language and thinking that we are often unaware of their impact, despite the crucial role of metaphors in communication, learning and creating meaning from experiences. A deeper understanding of how to recognize and work with client-generated and counselor-generated metaphors has great potential as an addition to the genetic counseling 'tool-box'. Here, we draw on studies from related health and psychotherapy fields to discuss how working purposefully with metaphors may offer a powerful way to enhance communication within a reciprocally engaged client-counselor relationship. Metaphors present ways to explain complex genetic concepts in a personally meaningful form, to gain a deeper understanding of client's experiences and emotions, to assist processing of experiences, emotions, and concepts, and to assist client and counselor to access and reflect on subconscious emotions, self-concept, and motivations. In addition, working with metaphors has been shown to facilitate coping and action. This paper sets the scene for why and how genetic counselors can utilize client-generated and counselor-generated metaphors purposefully in all areas of practice, including enhancing the therapeutic interaction with clients, as well as in supervision, training, cultural competence, and shaping of societal attitudes toward genetics.

Negotiating Novelty: Constructing the Novel within Scientific Accounts of Epigenetics

Epigenetics is regarded by many as a compelling domain of biomedicine. The purported novelty of epigenetics has begun to have various societal ramifications, particularly in relation to processes of responsibilisation. Within sociology, it has stimulated hopeful debate about conceptual rapprochements between the biomedical and social sciences. This article is concerned with how novelty is socially produced and negotiated. The article engages directly with scientists' talk and writings about epigenetics (as process and field of study). I aim to advance an explicitly sociological analysis about the novelty of epigenetics that underscores its social production rather than an account which participates in its reification. I attend to definitional skirmishes, comparisons with genetics, excitement and intrigue, and considerations of the ethical dimensions of epigenetics. Any assertions that epigenetics is exciting or important should not inadvertently elide reflexive consideration of how such characterisations might be part of the machinery by which they become real.

Heritable changeability: Epimutation and the legacy of negative definition in epigenetic concepts

Epigenetic concepts are fundamentally shaped by a legacy of negative definition, often understood by what they are not. Yet the function and implication of negative definition for scientific discourse has thus far received scant attention. Using the term epimutation as exemplar, we analyze the paradoxical like-but-unlike structure of a term that must simultaneously connect with but depart from genetic concepts. We assess the historical forces structuring the use of epimutation and like terms such as paramutation. This analysis highlights the positive characteristics defining epimutation: the regularity, oxymoronic temporality, and materiality of stable processes. Integrating historical work, ethnographic observation, and insights from philosophical practice-oriented conceptual analysis, we detail the distinctive epistemic goals the epimutation concept fulfils in medicine, plant biology and toxicology. Epimutation and allied epigenetic terms have succeeded by being mutation-like and recognizable, yet have failed to consolidate for exactly the same reason: they are tied simultaneously by likeness and opposition to nouns that describe things that are assumed to persist unchanged over space and time. Moreover, negative definition casts the genetic-epigenetic relationship as an either/or binary, overshadowing continuities and connections. This analysis is intended to assist practitioners and observers of genetics and epigenetics in recognizing and moving beyond the conceptual legacies of negative definition.

Communicating science: epigenetics in the spotlight

Given the public interest in epigenetic science, this study aimed to better understand media representations of epigenetics in national newspaper coverage in various regions in North America, Europe, and Asia. Content analysis was used to study media messages about epigenetics, their policy focus, and the balance of the reporting. We identified several recurring themes in the news reports, including policy messages relating to individual and societal responsibilities. We also found shortcomings in the media's portrayal of epigenetic science, and sought to identify potential causes by considering the underlying scientific evidence that the media reported on. A case study analysis showed that the results of epigenetic studies were often overstated in academic research publications due to common experimental limitations. We suggest that defining standardized criteria with which to evaluate epigenetic studies could help to overcome some of the challenges inherent in translating complex epigenetic research findings for non-technical audiences, and present a Press Kit template that researchers can adapt and use to aid in the development of accurate and balanced press releases.

Plasticity of the neural coding metaphor: An unnoticed rhetoric in scientific discourse

The convincing argument that Brette makes for the neural coding metaphor as imposing one view of brain behavior can be further explained through discourse analysis. Instead of a unified view, we argue, the coding metaphor's plasticity, versatility, and robustness throughout time explain its success and conventionalization to the point that its rhetoric became overlooked.

Self- and Other-Dehumanization Processes in Health-Related Contexts: A Critical Review of the Literature

Dehumanization is an everyday, pervasive phenomenon in health contexts. Given its detrimental consequences to health care, much research has been dedicated to understanding and promoting the humanization of health services. However, health care service research has neglected the sociopsychological processes involved in the dehumanization of self and others, in formal but also informal health-related contexts. Drawing upon sociopsychological models of dehumanization, this article will bridge this gap by presenting a critical review of studies on everyday meaning-making and person perception processes of dehumanization in health-related contexts. A database search was conducted in PsycINFO, Web of Science, Scopus, and PubMed, using a combination of keywords on dehumanization and health/illness/body; 3,229 references were screened; 95 full texts were assessed for eligibility; 59 studies were included. Most studies focused on informal contexts, reflecting a decontextualized and one-sided view of dehumanization (i.e., not integrating actors’ and victims’ perspectives). Despite the dominant focus on self-dehumanization, emerging perspectives uncover the role of processes that deny human uniqueness to others, and their individual determinants and consequences for mental health. A few studies bring to light the functions of a variety of dehumanizing body metaphors on self- and other-dehumanization. These trends in the literature leave several gaps, which are here critically analyzed to inform future research.

Epigenetics, ethics, law and society: A multidisciplinary review of descriptive, instrumental, dialectical and reflexive analyses

Epigenetics, defined as 'the study of mitotically and/or meiotically heritable changes in gene function that cannot be explained by changes in DNA sequence', has emerged as a promissory yet controversial field of scientific inquiry over the past decade. Scholars from many disciplines have formulated both optimistic and cautionary claims regarding its potential normative implications. This article provides a comprehensive review of the nascent literature at the crossroads of epigenetics, ethics, law and society. It describes nine emerging areas of discussion, relating to (1) the impact of epigenetics on the nature versus nurture dualism, (2) the potential resulting biologization of the social, (3) the meaning of epigenetics for public health, its potential influence on (4) reproduction and parenting, (5) political theory and (6) legal proceedings, and concerns regarding (7) stigmatization and discrimination, (8) privacy protection and (9) knowledge translation. While there is some degree of similarity between the nature and content of these areas and the abundant literature on ethical, legal and social issues in genetics, the potential implications of epigenetics ought not be conflated with the latter. Critical studies on epigenetics are emerging within a separate space of bioethical and biopolitical investigations and claims, with scholars from various epistemological standpoints utilizing distinct yet complementary analytical approaches.

Epigenetics in the public sphere: interdisciplinary perspectives

Despite the high public interest in epigenetics, few scholars have empirically investigated the forms, reasons and consequences of the public circulation of epigenetics. Using an original database focusing on 'lifestyle' or 'everyday' epigenetics, this article aims to promote an open-minded and interdisciplinary dialogue between the public appropriation of epigenetics and the current scientific state of the art. It raises three main questions: Are there any specific modes of circulation of epigenetics in the general public? Why does epigenetics seem so appealing to the public? Within the public repertoire of epigenetics, is it possible to identify some specific knowledge claims and, if so, given the current state of the art, what is their degree of accuracy? The article argues that the social diffusion of epigenetics frequently carries on beliefs and misconceptions about genetics and epigenetics. The social life of epigenetics fuels a collective 'illusion' of control and empowerment on the basis of which new markets expand. More unexpectedly, this article underlines the emergence of a new scientific culture, i.e. the 'scientifization' of the cultural appropriation of epigenetics. Our analysis can inform the scientific community about the current and evolving state of the public representation of epigenetics and help it frame outreach activities.

The Use of Figurative Language to Describe Frailty in Older Adults

INTRODUCTION

Frailty affects 15% of non-institutionalized older adults in the United States, yet confusion remains in defining and, in turn, assessing frailty. Figurative language, such as metaphor, can help to explain difficult scientific concepts and to form new theories. We aimed to examine the use of figurative language to describe frailty and to identify themes in the way figurative expressions are used. Understanding how frailty is described figuratively may offer insights for developing useful communication approaches in research settings.

METHODS

We performed a comprehensive review of editorials in the scientific literature to explore figurative language used to describe frailty in older adults. We categorized themes among the figurative expressions, which may help to inform how to effectively communicate about frailty.

RESULTS

We found 24 editorials containing 32 figurative expressions. The figurative expressions conceptualized frailty in six ways: 1) a complex, multifaceted concept; 2) an important issue in health and medicine; 3) indicative of something that is failing or faulty; 4) indicative of fragility; 5) representative of vulnerable, ignored persons; and 6) an opportunity for self-awareness and reflection.

DISCUSSION

Our review highlights the heterogeneity in depictions of frailty, which is consonant with the lack of a standardized definition of frailty. We also found a novel aspect to the concept of frailty, which merits attention: frailty characterized as an opportunity for self-awareness and reflection. Figurative language, which often juxtaposes familiar with challenging, complex concepts, can offer insights on issues in frailty research and holds potential as a tool for researchers to improve communication about this important and debated medical condition.

Gene-Environment Interplay in Child Eating Behaviors: What the Role of "Nature" Means for the Effects of "Nurture"

PURPOSE OF REVIEW

This narrative review describes the evidence for both genetic and environmental influences on child appetitive traits and suggests ways of thinking about how these interact and correlate to influence how a child eats.

RECENT FINDINGS

Emerging evidence from social network analysis, and from longitudinal studies questioning the direction of association between parent feeding behaviors and child obesity risk, suggest that children's genes may shape the environmental risk for obesity that they are exposed to. There is strong evidence that child appetitive traits are both heritable and shaped by the environment. Instead of thinking about how genetic and environmental factors operate independently on each appetitive trait, research needs to expand the current paradigm to examine how genes and environments interact and shape each other.

Who are the users of synthetic DNA? Using metaphors to activate microorganisms at the center of synthetic biology

Synthetic biology, a multidisciplinary field involving designing and building with DNA, often designs and builds in microorganisms. The role of these microorganisms tends to be understood through metaphors making the microbial cell like a machine and emphasizing its passivity: cells are described as platforms, chassis, and computers. Here, I point to the efficacy of such metaphors in enacting the microorganism as a particular kind of (non-)participant in the research process, and I suggest the utility of employing metaphors that make microorganisms a different kind of thing-active participants, contributors, and even collaborators in scientific research. This suggestion is worth making, I argue, because enabling the activity of the microorganism generates opportunities for learning from microorganisms in ways that may help explain currently unexplained phenomena in synthetic biology and suggest new experimental directions. Moreover, "activating the microorganism" reorients relationships between human scientists and nonhuman experimental participants away from control over nonhuman creatures and toward respect for and listening to them, generating conditions of possibility for exploring what responsible research means when humans try to be responsible toward and even with creatures across species boundaries.

'Your DNA, Your Say': global survey gathering attitudes toward genomics: design, delivery and methods

Our international study, 'Your DNA, Your Say', uses film and an online cross-sectional survey to gather public attitudes toward the donation, access and sharing of DNA information. We describe the methodological approach used to create an engaging and bespoke survey, suitable for translation into many different languages. We address some of the particular challenges in designing a survey on the subject of genomics. In order to understand the significance of a genomic result, researchers and clinicians alike use external databases containing DNA and medical information from thousands of people. We ask how publics would like their 'anonymous' data to be used (or not to be used) and whether they are concerned by the potential risks of reidentification; the results will be used to inform policy.

Synthetic biology, metaphors and responsibility

Metaphors are not just decorative rhetorical devices that make speech pretty. They are fundamental tools for thinking about the world and acting on the world. The language we use to make a better world matters; words matter; metaphors matter. Words have consequences - ethical, social and legal ones, as well as political and economic ones. They need to be used 'responsibly'. They also need to be studied carefully - this is what we want to do through this editorial and the related thematic collection. In the context of synthetic biology, natural and social scientists have become increasingly interested in metaphors, a wave of interest that we want to exploit and amplify. We want to build on emerging articles and books on synthetic biology, metaphors of life and the ethical and moral implications of such metaphors. This editorial provides a brief introduction to synthetic biology and responsible innovation, as well as a comprehensive review of literature on the social, cultural and ethical impacts of metaphor use in genomics and synthetic biology. Our aim is to stimulate an interdisciplinary and international discussion on the impact that metaphors can have on science, policy and publics in the context of synthetic biology.

Framing Strategies to Avoid Mother-Blame in Communicating the Origins of Chronic Disease

Evolving research in epigenetics and the developmental origins of health and disease offers tremendous promise in explaining how the social environment, place, and resources available to us have enduring effects on our health. Troubling from a communications perspective, however, is the tendency in framing the science to hold mothers almost uniquely culpable for their offspring's later disease risk. The purpose of this article is to add to the conversation about avoiding this unintended outcome by (1) discussing the importance of cognitive processing and issue frames, (2) describing framing challenges associated with communicating about developmental origins of health and disease and offering principles to address them, and (3) providing examples of conceptual metaphors that may be helpful in telling this complex and contextual story for public health.

Exploring the post-genomic world: differing explanatory and manipulatory functions of post-genomic sciences

Richard Lewontin proposed that the ability of a scientific field to create a narrative for public understanding garners it social relevance. This article applies Lewontin's conceptual framework of the functions of science (manipulatory and explanatory) to compare and explain the current differences in perceived societal relevance of genetics/genomics and proteomics. We provide three examples to illustrate the social relevance and strong cultural narrative of genetics/genomics for which no counterpart exists for proteomics. We argue that the major difference between genetics/genomics and proteomics is that genomics has a strong explanatory function, due to the strong cultural narrative of heredity. Based on qualitative interviews and observations of proteomics conferences, we suggest that the nature of proteins, lack of public understanding, and theoretical complexity exacerbates this difference for proteomics. Lewontin's framework suggests that social scientists may find that omics sciences affect social relations in different ways than past analyses of genetics.
