How do you navigate a nonlinear, “squiggly line” career in science and public health? Dr. Katelyn Jetelina, an epidemiologist and scientific communicator, explores challenges of science communication within academia—from cultural resistance to misaligned incentives—and why so much vital research never reaches the public. Joined by Dr. John Schwartzberg, Professor Emeritus, School of Public Health, they discuss the growing opportunities for scientists both within and beyond academia, and what needs to change to better support public impact across all career paths.

Espiritismo traces its roots to the sacred knowledge of West and Central African peoples carried into the Americas by enslaved ancestors between the 15th and 19th centuries. Marta Moreno Vega, Ph.D., scholar and co-founder of Corredor Afro, explores how these traditions—sustained in Cuba, Haiti, Brazil, Puerto Rico, other Caribbean islands, and U.S. urban centers—function as systems of memory, survival, and continuity. Drawing on personal and family experiences, Moreno Vega reflects on the challenges of centering African Diaspora spiritual practices in academia, which often privileges “objective” distance over embodied knowledge. She emphasizes the resilience of these ancestral practices and the ways they continue to manifest in contemporary life through remembrance, ritual, and cultural expression.

Public health often works behind the scenes—preventing illness, protecting communities, and generating research that too often stays hidden behind paywalls. In a world of eroding trust and rising falsehoods, Dr. Katelyn Jetelina, an epidemiologist and scientific communicator, explores how we can make the value of public health visible: by telling better stories with data, making science more accessible, and ensuring communities see themselves in the work before, during, and after crisis.

Peter Godfrey-Smith, Professor of History and Philosophy of Science at the University of Sydney, explores the evolutionary roots of consciousness by surveying animal evolution and the emergence of felt experience in several lineages. He examines two central philosophical questions: how such experience might arise gradually, existing in partial forms, and whether it represents a single unified feature with variations or instead a cluster of distinct traits. Author of "Darwinian Populations and Natural Selection," and "Living on Earth: Forests, Corals, Consciousness and the Making of the World," Godfrey-Smith brings his expertise in philosophy of biology and mind to illuminate how consciousness may have emerged and why its origins remain a profound puzzle.

Legal scholar Annabel Brett explores the idea of “moral possibility”—the boundary between what laws demand and what people can realistically or ethically be expected to do. Drawing from early modern thinkers like Aquinas, Suarez, and Hobbes, Brett shows how moral impossibility has long shaped debates about legal obligation, resistance, and political agency. Commentators Melissa Lane and David Dyzenhaus join the discussion, examining how this concept applies to everything from climate action and military conscription to unjust regimes and democratic norms. Together, they highlight how institutions, customs, and time shape the space between legal duty and human capacity—and why recognizing this gap is vital to both justice and legitimacy.

Political theorist Annabel Brett of Cambridge University explores how the concept of “moral possibility” shapes law, politics, and public obligation. She explains that laws must be realistic for people to follow—what is morally possible varies by individual, culture, time, and circumstance. Drawing on early modern Catholic legal theory, Brett discusses how extreme demands (like enduring war or plague) may justify higher expectations, but only temporarily. She examines how colonial Spanish officials misused this framework to justify forced labor in Peru, wrongly claiming it aligned with indigenous customs. Brett contrasts this with more democratic approaches to law, like Domingo de Soto’s defense of beggars’ rights, which take individuals’ real conditions seriously. Ultimately, she shows how moral possibility is deeply tied to time, virtue, and justice. Commentary is provided by David Dyzenhaus of the University of Toronto.

It's time for a new narrative for the ocean, one that reflects current scientific knowledge and acknowledges innovative new partnerships and solutions that center the ocean in our future. In this program, Jane Lubchenco, Professor of Marine Biology at Oregon State University and with expertise in the ocean, climate change, and interactions between the environment and human well-being, talks about the two current dominant narratives for the ocean are anchored in the past. The older one considers the ocean to be so vast, bountiful, and resilient that it is simply too big to fail. This first narrative drives pollution and over-exploitation of resources. A second, more recent narrative is that the ocean is now so depleted, polluted, and disrupted, and the drivers of those outcomes are so powerful and complex, that the ocean is simply too big to fix. A third, new narrative is emerging, based on scientific findings, existing solutions, and innovative partnerships and policies. This new narrative acknowledges that the ocean is central to a safe, clean, healthy, just, and prosperous future. This new narrative tells us that the ocean is neither too big to fail, nor is it too big to fix. But it is too important and too central to our future to ignore.

Three major global challenges – climate change, loss of biodiversity and its benefits, and inequality and inequity among people – are typically tackled within three separate silos. However, scientific knowledge tells us that the three are inextricably linked. If the problems are not considered together, solutions to one may undermine solutions to the others. Moreover, more holistic, integrated solutions can deliver multiple co-benefits. Success requires integrated solutions. Jane Lubchenco, Professor of Marine Biology at Oregon State University, talks about the historically ambitious, innovative policies implemented by the Biden-Harris Administration to achieve this integration. Lubchenco is a marine ecologist with expertise in the ocean, climate change, and interactions between the environment and human well-being. From 2021-2025, she served as Deputy Director for Climate and Environment in the White House Office of Science and Technology Policy.

There's a powerful idea in the history of European legal and political thought: that laws must be possible for people to follow. Annabel Brett, professor of Political Thought and History at Cambridge University, describes how from ancient times through the Renaissance, thinkers believed that demanding the impossible—whether physically or psychologically—was a hallmark of tyranny. A classic example is Pharaoh in the Book of Exodus, who ordered the Israelites to make bricks without straw. Brett analyzes how legal thinkers balanced the need for law to be both realistic and aspirational, and how these ideas shaped the development of modern legal systems. Brett is joined by Princeton University's Melissa Lane for commentary. Series: "UC Berkeley Graduate Lectures" [Public Affairs] [Humanities] [Show ID: 40429]

The "energy transition" is actually a shift from relying on fossil fuels (like coal, oil, and gas) to using metals to generate energy. However, extracting metals has always been a significant environmental and political issue, especially for cities. This problem has been around for centuries, even ancient Roman writers wrote about it. In this program, Helen Thompson, Professor of Political Economy at Cambridge University, talks about the historic use of fossil fuels and its economic, social and environmental impacts to the transition today to extracting metals for energy, dominated by China. Thompson points out that extracting resources will always have environmental and social costs. To mitigate these risks, she says we need to find ways to reduce international competition and ecological damage. This requires acknowledging that the idea of endless progress, which was fueled by fossil fuels, has its limits. And she says we must prioritize sustainability and responsible resource management to create a better future. Series: "UC Berkeley Graduate Lectures" [Public Affairs] [Business] [Show ID: 40428]
