Food adulteration with toxic chemicals is a global public health threat. Lead chromate adulterated spices have been linked with lead poisoning in many countries, from Bangladesh to the United States. This study systematically assessed lead chromate adulteration in turmeric, a spice that is consumed daily across South Asia. Our study focused on four understudied countries that produce >80 % of the world's turmeric and collectively include 1.7 billion people, 22 % of the world's population. Turmeric samples were collected from wholesale and retail bazaars from 23 major cities across India, Pakistan, Sri Lanka, and Nepal between December 2020 and March 2021. Turmeric samples were analyzed for lead and chromium concentrations and maximum child blood lead levels were modeled in regions where samples had detectable lead. A total of 356 turmeric samples were collected, including 180 samples of dried turmeric roots and 176 samples of turmeric powder. In total, 14 % of the samples (n = 51) had detectable lead above 2 μg/g. Turmeric samples with lead levels greater than or equal to 18 μg/g had molar ratios of lead to chromium near 1:1, suggestive of lead chromate adulteration. Turmeric lead levels exceeded 1000 μg/g in Patna (Bihar, India) as well as Karachi and Peshawar (Pakistan), resulting in projected child blood lead levels up to 10 times higher than the CDC's threshold of concern. Given the overwhelmingly elevated lead levels in turmeric from these locations, urgent action is needed to halt the practice of lead chromate addition in the turmeric supply chain.

When you think of the climate crisis and the major impact it will have upon all corners of the world, one nation stands out as the epicenter of the unfolding cataclysmic changes: Bangladesh.

When Stephen Luby, MD, began working there two decades ago, the South Asian country was facing tremendous climate stress brought on by intermittent floods, extreme heat, cyclones and drought that threatened human life.

Methane emitted and flared from industrial sources across the United States is a major contributor to global climate change. Methanotrophic bacteria can transform this methane into useful protein-rich biomass, already approved for inclusion into animal feed. In the rapidly growing aquaculture industry, methanotrophic additives have a favourable amino acid profile and can offset ocean-caught fishmeal, reducing demands on over-harvested fisheries. Here we analyse the economic potential of producing methanotrophic microbial protein from stranded methane produced at wastewater treatment plants, landfills, and oil and gas facilities. Our results show that current technology can enable production, in the United States alone, equivalent to 14% of the global fishmeal market at prices at or below the current cost of fishmeal (roughly US$1,600 per metric ton). A sensitivity analysis highlights technically and economically feasible cost reductions (such as reduced cooling or labour requirements), which could allow stranded methane from the United States alone to satisfy global fishmeal demand.

With what now seem like almost weekly product scandals, recalls, and supply chain exposes, the public increasingly wants to know more about the products they are putting in, on, and around their families. Until recently, consumers had no way to find out the full impacts of the products they consumed. However, with advances in information technologies, product assessment methodologies, and web and mobile platforms, there is now a real potential to radically increase transparency in consumer markets and global supply chains. Dara O'Rourke, Associate Professor at UC Berkeley, will discuss an experiment in providing information to the public about the environmental, social, and health impacts of products and companies: GoodGuide. GoodGuide's award-winning web and iPhone apps have been featured recently in the New York Times, Newsweek, Time, and even Oprah's Magazine! Dara will discuss GoodGuide's long-term vision, current strategies, and the information technologies they are applying to this challenge.

Dara O’Rourke is an Associate Professor at the University of California, Berkeley, and the co-founder of GoodGuide. Dara’s research focuses on systems for monitoring the environmental, labor, and health impacts of global production systems. His research has been featured in The New York Times, The International Herald Tribune, The Boston Globe, The Los Angeles Times, The Economist, Business Week, Newsweek, Time, and TechCrunch. Dara has served as a consultant to international organizations such as the World Bank, the United Nations Development Programme, the Organization for Economic Cooperation and Development, and a wide range of domestic and international non-governmental organizations. He has degrees in Mechanical Engineering, Political Science, and Energy and Resources, and he previously taught at MIT.

GoodGuide seeks to revolutionize how consumers see and interact with products and companies. GoodGuide provides a suite of tools that offer information about the environmental, social, and health performance of products and companies to consumers at the point of purchase (through web and mobile apps), and that empower people to screen and compare products based on their personal values and concerns. GoodGuide's tools seek to empower millions of consumers to buy products that better match their values, to avoid products that are detrimental to their health, the environment, or issues they care about, and to participate in a more transparent marketplace.

Projects to enhance health security and child survival in Africa with improvements in water and sanitation, examine why poor business-management practices persist in India, study the relationship of legal courts to politics and human rights, and understand why the Middle East has lagged in economic progress were recent recipients of grants totaling just under $1 million from Stanford's Presidential Fund for Innovation in International Studies.

"These projects have great potential to advance academic knowledge, social capital and human development around the world, and to create a healthier, more promising future for hundreds of millions of people," President John Hennessy said. "When we launched The Stanford Challenge, we committed to marshal university resources to address the great challenges of the 21st century in human health, the environment and international affairs, and it is gratifying to see the response from our remarkable faculty."

The 2008 projects and their principal investigators follow:

Enhancing Health Security Through Infrastructure and Behavioral Intervention: Water, Sanitation and Child Survival in Africa. Alexandria Boehm and Jenna Davis, Civil and Environmental Engineering; Abby King, Health Research and Policy and Medicine; Gary Schoolnik, Medicine and Microbiology and Immunology. The project seeks to improve the health and well-being of the 1.2 billion people in low-income countries who lack access to clean water and the 2.6 billion who lack access to sanitation services, with a focus on mortality reduction in children. It will be carried out in sub-Saharan Africa, where the toll of water- and sanitation-related illness on health is severe, and will investigate the extent to which information and education about water and sanitation at the household level motivates behavior changes that result in reduced morbidity. Results will inform international efforts to design and implement effective water supply and sanitation interventions for more than 400 million Africans currently lacking access.

Why Are Indian Firms Poorly Managed? A Survey and Randomized Field Intervention. Nicholas Bloom and Aprajit Mahajan, Economics; Thomas C. Heller and Erik Jensen, Law School; John Roberts, Graduate School of Business. The biggest single reduction in poverty in the history of mankind was achieved by the industrialization of China since 1978, which lifted almost 500 million people out of poverty. India has not experienced this level of poverty reduction because its manufacturing firms have not achieved the productivity gains seen in China. Recent evidence suggests one key factor is the poor management practices adopted by Indian firms. This project examines why poor management practices persist in India and are much more common there. It focuses in particular on evaluating the relative importance of informational, legal and development barriers. The project will undertake a field survey of Indian firms to evaluate their knowledge of modern management techniques and a field intervention aimed at upgrading management practices in a randomized sample of Indian firms, comparing their progress to a control group of untouched firms.

Courts, Politics and Human Rights. Joshua Cohen, Philosophy, Political Science, and Law School; Terry L. Karl, Political Science; Jenny S. Martinez, Law School; Helen Stacy, Law School. This project examines the role of courts as the centerpiece of strategies for promoting human rights by asking if courts should be a preferred human rights venue or if there are other more accessible and effective ways to secure human rights. It addresses three broad themes: the interplay between national, regional and international courts in the protection of human rights; the role of governments and nongovernmental organizations in influencing legal proceedings; and how courts construct historical truth and shape public opinion, memory, attitudes and discourse about human-rights abuses. The multidisciplinary project will span countries, regions, issue areas and historical timeframes to ask what reasonably can be expected from international, regional and domestic courts in safeguarding human rights.

The Middle East and the World Economy. Matthew Harding, Economics; Lisa Blaydes, Political Science. This project examines why the Middle East has lagged in economic progress compared to much of the developing world and the implications of this underdevelopment for two overarching trends in Middle Eastern politics today: authoritarian government and Islamic fundamentalism. The researchers also will examine how political instability originating in the Middle East has affected world oil prices and world markets by constructing economic models of the world economy. The project seeks broadly to understand the macro- and microeconomic determinants of Islamic fundamentalism and authoritarian rule, and the extent to which these two outcomes have affected the stability and prosperity of the world economy. It measures global factors resulting from increased globalization and quantifies their impact on the development of economies in the Middle East.

The $3 million Presidential Fund for Innovation in International Studies was first established in 2005 by the Office of the President and the Stanford International Initiative to support new cross-campus, interdisciplinary research and teaching among Stanford's seven schools on three overarching global challenges: pursuing peace and security, reforming and improving governance at all levels of society, and advancing human well-being.

The first $1 million in interdisciplinary grants was awarded in February 2006; the second round of grants was awarded in February 2007.

"In all three rounds of funding, it has been heartening to see the imaginative and innovative ways that Stanford faculty are combining intellectual forces across disciplines to tackle some of the most pressing and persistent problems of our day," said Coit D. Blacker, chair of the International Initiative Executive Committee and director of Stanford's Freeman Spogli Institute for International Studies. "It is especially gratifying to see the younger faculty competing for these grants, eager to generate new knowledge and new solutions and help train a new generation of leaders."

Priority in funding has been given to teams of faculty who do not typically work together, who represent multiple disciplines and who address issues falling broadly within the three central research areas of the Stanford International Initiative. Projects are to be based on collaborative research and teaching involving faculty from two or more disciplines and, where possible, from two or more of the university's seven schools.
