Jordi Soriano Fradera is a Spanish physicist and Associate Professor of Physics at the University of Barcelona, where he leads the Neurophysics Group and serves as vice-director of the university’s Institute of Complex Systems (UBICS). He earned his PhD in condensed matter physics at the University of Barcelona before completing postdoctoral research in developmental biology in Germany and in neuroscience at the Weizmann Institute of Science in Israel. For more than fifteen years, his group has developed in vitro neuronal cultures and biophysical models to study how connectivity and collective dynamics give rise to brain function, and how they break down in neurological disease. He has collaborated closely with medical teams on Parkinson’s, Huntington’s, Sanfilippo, and Alzheimer’s disease, and coordinated research under the EU Horizon 2020 NEU-CHiP project on biological computing. In this InterDialogue, recorded in Soriano’s lab among live neuronal cultures and imaging equipment, we trace his path from studying fluid fronts in porous media as a condensed matter physicist to a twenty-year career in neurophysics. We discuss how his group engineers rat and human stem-cell-derived neuronal cultures to model the brain’s structural and functional connectivity and to serve as disease models for Parkinson’s, Huntington’s, Sanfilippo, and Alzheimer’s, the prospects and limits of cell transplantation and personalized medicine, and why Soriano estimates a twenty-year horizon before such approaches reach the clinic. We also discuss his work on network damage, resilience, and criticality in neuronal cultures, the NEU-CHiP project’s attempt to train living neurons to perform computation, neuromorphic chips that mimic neurons in silicon, and a striking experiment in which donated human brain tissue was made to play back a melody fed to it through a robotic piano. We close by considering the ethical stakes of coupling neuronal cultures with robots and augmented-human technologies, Soriano’s efforts to help build neuroscience...

Ashish Kothari is an Indian environmentalist, author, and founding member of Kalpavriksh, a non-profit working on environmental and social justice issues at local, national, and global scales. He has taught at the Indian Institute of Public Administration and the National Law School of India University in Bengaluru, coordinated India’s National Biodiversity Strategy and Action Plan process, and serves as a judge on the International Tribunal on the Rights of Nature. He also helps coordinate the Vikalp Sangam alternatives confluence, the Global Tapestry of Alternatives, and the Radical Ecological Democracy initiative. Over more than four decades, he has authored, co-authored, or edited more than 30 books, along with hundreds of articles. In this wide-ranging InterDialogue, Kothari traces his path from a childhood watching Delhi’s urban forests disappear into a lifetime of environmental and social justice work, and how that activism grew into Kalpavriksh and wider networks like the Vikalp Sangam, the ICCA Consortium, and the Global Tapestry of Alternatives. We discuss the biocultural and ideological diversity of the Indian subcontinent, his concept of “outscaling” as an alternative to conventional growth models, and how Adivasi and indigenous rights in India compare with frameworks in Latin America, shaped by very different histories of colonization and violence. Kothari also reflects on decades of writing—from a self-published newsletter in 1980 to the hundred-essay volume Pluriverse—and how it has supported grassroots movements and reached younger generations. We go on to explore the rights of nature movement in India—including the personhood granted to the Ganga and Yamuna rivers and the transboundary politics of South Asia’s rivers—before Kothari lays out earthy governance, his framework for moving beyond the legal limits of rights of nature toward a form of decision-making in which the rest of the natural world is already part of the process, illustrated through examples from a...

In this guest InterDialogue, folklorist and InterPlex content and operations strategist Rowan Glass converses with K. Brandon Barker, Associate Professor of Folklore at Indiana University Bloomington and editor of Children’s Folklore Review. Barker co-authored the book Folk Illusions with Claiborne Rice, introducing the term “folk illusions” to study children’s play forms in relation to the science of perception and cognition. He has also written on animal cognition and the folklore of science with comparative psychologist Daniel Povinelli, with whom he co-edited the book The Aesop’s Fable Paradigm. For several years, Barker led the Folklore and Science Section of the American Folklore Society, which he helped found. The conversation begins with two notoriously murky words: how to define both folklore and science when both terms carry so much baggage? Barker makes the case that “the folk” are far less naive than some scientists assume, and that folklore’s ethnographic methods can offer insights into problems like vaccine hesitancy and misinformation by taking seriously perspectives often overlooked by or inaccessible to scholars in other fields. Glass then addresses Barker’s research on folk illusions and what children’s play reveals about adultcentrism, body acquisition, and the science of perception. They probe the epistemological stakes of folklore scholarship in relation to the natural sciences, asking whether folklorists can or should advance universal claims and broad theoretical frameworks. They also talk about computation folklore and Barker’s work on the folklore of animal cognition. The conversation then turns toward humans’ seemingly inherent tendencies toward anthropomorphism and human exceptionalism—whether applied to animals or artificial intelligence. Barker asserts that our seemingly inherent penchant for projecting human qualities onto the non-human world might be more powerful, and perhaps more dangerous, than we realize.

Ciro Cattuto is an Italian physicist and complexity scientist whose work explores the intricate relationships between human behavior and digital technologies. Since 2008, he has served as Scientific Director of the ISI Foundation, based in Turin, Italy. He is also the founder and principal investigator of the Sociopatterns Collaboration. Throughout his career, Cattuto has held a range of influential research, fellowship, advisory, and board positions in Italy, the United States, and Japan. In this thought-provoking InterDialogue, we trace Cattuto’s intellectual journey from theoretical solid-state physics into complex systems science, a multicultural path that unfolded across three continents. We also discuss his contributions to data science and complex network research, including his work on some of the first digital social networks. We then examine what it means to conduct interdisciplinary research and how such collaborations can be cultivated more effectively. Cattuto also draws on his experience at the intersection of complex networks and epidemiology as a case of interdisciplinary bridge-building in practice. We further discuss the research priorities and guiding principles of the ISI Foundation, especially in relation to its current focus on computational social science and opportunities for policy impact. Finally, we reflect on both the promise and the profound challenges associated with the growing integration of artificial intelligence into scientific research and society more broadly.
