Bruce Ames — Nutritional deficiencies and trace synthetic chemicals: Putting health risks into perspective

Tuesday, April 23, 2013

Humanities 1, Room 210

Bruce N. Ames (Senior Scientist, Nutrition and Metabolism Center, Children’s Hospital of Oakland Research Institute (CHORI) and Professor of Biochemistry and Molecular Biology, UC Berkeley)

Bruce Ames’ research in nutritional biochemistry has examined exposure to health risks from a number of perspectives. Early in his career he developed the Ames test, an inexpensive method to measure the mutagenic and carcinogenic potential of chemicals which has become an essential tool of contemporary biochemistry. Although it contributed to public fears about synthetic chemicals, the common carcinogenic effects of ‘natural’ chemicals led Dr. Ames to assert that these fears were largely unfounded or exaggerated. More recently, his research has focused on the hidden biochemical costs of vitamin deficiencies, which are widespread even in wealthy nations. His triage theory posits that the human body protects against short term consequences of essential vitamin deficiencies by reducing the production of longevity proteins that are markers of long term health. This discovery led to his lab’s creation of CHORI-Bars, nutritional food bars that provide high densities of essential vitamins and minerals with very few calories. Preliminary research indicates that resolving nutritional deficiencies in this fashion can have positive effects on a wide range of health problems in wealthy and poor economies alike.

In this presentation, Dr. Ames will discuss the triage theory and what it means for the relative risks of competing nutritional strategies. Have food system reformers significantly over-stated the risks of synthetic chemicals to human health? Does the emphasis on reducing synthetic chemicals actually lead to more negative health outcomes, such as cancer, by making fresh fruits and vegetables more expensive? Can highly-engineered foods such as CHORI-Bars provide the least expensive solutions to a wide variety of negative health outcomes?

Jenny Reardon’s op-ed sparks conversation about medical and genetic privacy

SJRC Co-Director Jenny Reardon published an Op-Ed in the San Francisco Chronicle on March 2, 2013, “Should patients understand that they are research subjects?” In the article she recounts visiting a physician at UC San Francisco and not being able to parse the standard informed consent to having tissues and/or medical data used anonymously in medical research. At the heart of problem is a confusing mix of U.S. case law that denies ownership over one’s bodily tissues once they have left one’s body, medical privacy standards that require providers and researchers to inform you that they may use the tissues for research without directly requesting permission, and the speed at which medical advances are occurring. Given these conditions, it is actually imposible to know what one is consenting to when one signs these ubiquitous forms, making that ‘consent’ tenuous at best. Reardon, whose research examines the social, ethical political dynamics of biomedicine and genomics, notes that even experts like her are in the dark about how their tissues might be used in the near future, and recent research has shown that while researchers may aspire to keeping tissues and data anonymous it is no longer technically feasible.

I have spent two decades studying this minefield, and even I had a hard time making sense of what it might mean for these researchers to have access to my samples. For example, UCSF would be required by law to make my samples “anonymous,” yet research published in Science the day of my visit revealed that even anonymous samples can be reidentified. Does this mean that information gained from my samples might be linked back to me?

Reardon cites recent developments in patient consent at the University of Washington medical centers as a model for UCSF and other providers to adopt. At the University of Washington, patients are able to opt out of research without their physicians knowing, and thus not feel as if they are risking their access to care. Additionally, Reardon supports giving patients more rights to affirmatively opt in to research whenever their tissues or data is desired by researchers.

The San Francisco Chronicle editorial board also published an editorial in support of Reardon’s proposal. The editors suggest that as the US Department of Health and Human Services revises its standards for medical consent, they should keep these principles in mind:

— Patients may not have legal “property,” but they still have rights. Regulators should err on the side of more patient disclosure, not less.

— Compensation is going to be a big question going forward, but it doesn’t have to be monetary. If there’s no longer a way to provide patients with anonymity, will they have free or reasonably priced access to medical developments that come about as a result of their cells or DNA?

— Standardized disclosures should be encouraged throughout the industry. Different institutions have widely varying policies. Patients don’t deserve to be confused.

In response to these two pieces, UCSF’s Elizabeth A. Boyd, associate vice chancellor for ethics and compliance, and Daniel Dohan, associate professor of health policy and social medicine, noted that the success of medical research rests on relationships of trust between physicians, researchers and patients. The development of personalized medicine, which promises to revolutionize health care by tailoring treatments to individuals, will require willingness on the part of patients to provide samples for research and testing. Boyd and Dohan note that UCSF supports revising consent standards, and cite the recent creati0n of EngageUC, an initiative on the part of UC physicians and faculty to develop new comprehensive guidelines.

We want to develop a consent process and a set of policies that will help ensure that all patients – whether they have volunteered for specific research, are donating leftover tumor samples, or are being admitted to the hospital for care – truly understand what information may be gleaned from their samples, how that information will be used, whom it will be shared with, and what privacy controls can – and cannot – be guaranteed.

Reardon and the rest of the UCSC Science & Justice Research Center will continue to contribute to these conversations.

Critical Nutrition Symposium

March 8, 2013

9:00AM-5:30PM

261 Social Sciences I

Advice about what to eat for health and well being is pervasive in the modern world, and such advice is delivered as if it were uncontroversial, universally applicable, welcome, and effective. When it appears not to work, rather than reflection on the scientific, cultural, and sociological underpinnings of the endeavor, the response has been for more informative food labels and more emphasis on food education. What’s wrong or missing in conventional nutritional practice? What are its effects in terms of human health and social justice? What other approaches might work better? This symposium will bring together scholars from multiple disciplines and perspectives to comment on the content and delivery of nutritional science. Invited guests include Charlotte Biltekoff (American Studies and Food Science, UC Davis), Jessica Hayes-Conroy (Women’s Studies, Hobart and William Smith Colleges), Adele Hite (Public Health, University of North Carolina-Chapel Hill), Aya H. Kimura (Women’s Studies, University of Hawai’i-Manoa), Hannah Landecker (Sociology and Center for Society and Genetics, UCLA), and Jessica Mudry (Center for Engineering in Society, Concordia University). UCSC food scholars Julie Guthman, Melissa Caldwell, Nancy Chen, and Jake Metcalf will provide commentary.

This event is sponsored by the Multi-campus Research Program on Food and the Body and the “Knowing Food” Research Cluster of the Center for Global, International, and Regional Studies. Additional support has been provided by the Community Studies Program, the Science & Justice Research Center, the Department of Environmental Studies, and the Department of Sociology.

Please RSVP to Lisa Nishioka (global@ucsc.edu) if you plan to attend.

Measuring and Predicting Carbon Absorbed in Reforestation and Averted Forest Fires: Problems of communicating uncertainty about landscape change

Karen Holl (UCSC, Environmental Studies)

Maggi Kelly (Dept. of Environmental Sciences, Policy & Management, UC Berkeley)

Tim Forsyth (Department of International Development, London School of Economics)

 

Over the last few years the contribution of deforestation and forest fires to climate change has come to be of increasing interest, even as new technologies of remote sensing and modeling have made it possible to measure and predict landcover change with unprecedented accuracy. These technologies have made it possible to imagine environmental policies which compensate landowners for averted deforestation (known as REDD, Reduced Emissions through Degradation and Deforestation), or to support thinning forests in order to prevent forest fires. However, increased precision also introduces new problems of communicating uncertainty to policymakers and of gaining the trust of the general public. Professor Holl will talk about the challenges of including tropical forest restoration in proposed markets in carbon offsets, Professor Kelly will talk about her work with remote sensing technologies such as LIDAR in order to measure California forests and to inform the general public about forest conditions. Tim Forsyth is a specialist in political approaches to environmental change and international development, and will moderate a conversation about the challenges of communicating uncertain knowledge about forests to policymakers and other audiences.

Seeding Sustainability: Hunger, BioTech, and the Future of Food Systems

Saturday February 23, 2013

7:00-10:00PM

UCSC Media Theater

Confirmed Speakers:

Miguel Altieri (UC Berkeley)

Eric Holt-Gimenez (Food First)

Kent Bradford (UC Davis)

Moderator: Jacob Metcalf (UCSC Science & Justice Research Center)

Registration (free) is kindly requested.

In collaboration with the UCSC Center for Agroecology and Sustainable Food Systems, the Science & Justice Research Center will host a panel discussion on the role of genetically modified crops within sustainable food systems in the global South. Food and agroecology activist and scholar Dr. Vandana Shiva will headline a panel with diverse perspectives from crop science, philanthropy. This panel will cap the CASFS weekend-long gathering and seed exchange event Strengthening the Roots: Seeds and Justice Convergence.

Two decades of experience with GMO crops, including mixed assessments of environmental impact and increased yield, indicate that controversies about biotech agriculture is not just (or even primarily) about the modified plants themselves. Rather, a complex social system travels with the plants. This system includes intellectual property, legal and political regimes, chemical inputs, industrialized and centralized food processing, farmer debt and much more. As the debate over GMO crops has evolved, particularly in the global South, the controversies have shifted from genetic modification techniques to the appropriateness of that social system for providing environmentally beneficial and economically secure food systems. Thus, this panel seeks to investigate the question of under what conditions ag-biotech is capable of providing sustainable—in all its ecological, cultural, and economic connotations—food systems in the global South? And are achieving those conditions both plausible and worth whatever trade-offs may be made in pursuit of extending and improving upon more traditional modes of growing food?

Mast Fruiting and Ectomycorrhizal Associates: How Looking Below Ground Reshapes Above Ground Ecologies and Politics

February 19, 2013

4:00-6:00PM

Engineering 2, Room 599

Lisa Curran (Woods Institute for the Environment/Department of Anthropology, Stanford University)

Respondents: Anna Tsing (Anthropology, UCSC) and Andrew Mathews (Science & Justice Research Center and Anthropology, UCSC)

Lisa Curran is an anthropologist and tropical ecologist who, over the last twenty five years, has carried out extensive research on forest ecology and plant/mycorrhizal relations in Indonesian forests. Through her engagement in policy research and advocacy she has participated in key forest policy conversations, including through her criticism of oil palm plantations in Latin America and South East Asia. Lisa’s current interdisciplinary research programs examine the effects of land use change, climate, drought and fire on carbon dynamics and biodiversity; and impacts of governmental policies and industrial practices on ecosystems and rural livelihoods in Asian and Latin American tropical forests. Today she will talk to us about her research on the relationship between below ground ectomycorrhyzal associates and above ground mast fruiting by important dipterocarp tree species. In a public conversation with Anna Tsing (Anthropology, UCSC) and Andrew Mathews (Science & Justice Research Center and Anthropology, UCSC) she will talk about how this research has informed her engagement with and criticism of oil palm plantations, and about how it broadens competition models that have historically been dominant in ecology.

Recent special issues edited by Science & Justice members, past and present

A number of past and present Science & Justice members have recently edited special editions of scholarly journals focussed on themes commonly explored in Science & Justice colloquia and courses. These collections highlight the ways in which S&J facilitates thinking across boundaries and gathering around interesting objects.

Assistant Director of the S&J Research Center  Jacob Metcalf and longtime friend of S&J, Thom van Dooren (University of New South Wales), co-edited an edition of Environmental Philosophy (9:1) titled Temporal Environments: Rethinking Time and Ecology. The collection of essays addresses the role that temporality, or lived time, should have in environmental philosophy, and especially ethics. The role of time in environmental ethics has largely been restricted to an empty container for human agency to do good or ill. By understanding time as material, produced, constructed, maintained, lived, multiple, and a more-than-human concern, the authors in this collection are able to ask which times are liveable for humans and non-humans alike. This topic grew out of Science & Justice discussions, especially the Slow Science event in Fall 2011.

Astrid Schrader (York), a founding member of the Science & Justice Working Group, co-edited with Sophia Roosth (Harvard) a special issue of differences: A Journal of Feminist Cultural Studies (23:3) titled Feminist Theory Out of Science. The issue features articles by a number of Science & Justice members and friends, including Karen Barad, co-Director of the Science & Justice Training Program. Attending to the rich entanglements of scientific and critical theory, contributors to this issue scrutinize phenomena in nature to explore new territory in feminist science studies. With a special focus on relating theory to method, these scholars generate new feminist approaches to scientific practice. What emerges from these diverse essays is an approach to critical thinking that inhabits, elaborates, and feeds upon scientific theory, holding feminist theory accountable to science and vice versa.

Lindsay Kelley (Public Library of Science), an early member of the Science & Justice Working Group, and Lynn Turner (Goldsmiths) co-edited an issue of parallax (19:1) titled bon appétit. This issue includes a contribution from S&J Assistant Director, Jacob Metcalf, on the ethics of cultured meat and the stories we tell about technoscientific advances. bon appétit explores the limits of eating, confronting the boundaries between self and other, filth and food.  At the time of writing escalating food costs – especially as linked to climate change – provoke daily crises, demonstrating the urgency of a wholesale rethinking of the matter of what, how and who we eat. The essays engage different strategies and target different aspects of this erstwhile basic need.

Forthcoming shortly as a special issue in Science Technology & Human Values, S&J advisory board member Laura Mamo (SFSU) and Jennifer Fishman (McGill) have collected articles on the Entanglements of Science, Ethics and Justice. This issue grew out of a conference about topics in science and justice at SFSU, including an article on genomics and justice by Jenny Reardon, co-Director of the S&J Research Center.

Karen Barad provides keynote address to “MATTERING: Feminism, Science and Materialism” conference

Karen Barad, co-Director for the Science & Justice Training Program, will provide the keynote address at the upcoming feminist science studies conference at CUNY, MATTERING: Feminism, Science and Materialism.

This conference, organized jointly by the Center for the Study of Women and Society, the Committee on Interdisciplinary Science Studies and the Advanced Research Collaborative at the Graduate Center, City University of New York, will engage with feminist perspectives on the onto-epistemological questions raised by the materialist turn.

In the past decade, feminist theory has elaborated new materialist perspectives to re-imagine nature, biology, and matter more generally and to critically address new developments in biology, physics, neuroscience and other scientific disciplines. This scholarship revisits the relationship between human corporeality and subjectivity, questions and redefines the boundaries of human and non-human and nature and culture, and elaborates on their mutual entanglements. New feminist theories address materialization as a complex and open process and matter as lively and productive. The conference will address: the intellectual and scientific context of the new turn toward materialism; the relation of matter (including the biological body) to the social; the insights, knowledge and methodologies offered by the new materialist studies of science; the political implications of neo-materialism for feminism as a project, theory and a movement for social justice; theoretical innovations for addressing material-discursive relations and the epistemological questions they raise; and empirical research using materialist feminist frameworks.
