OpenAI researcher Adam Kalai sits down with UC San Diego professor Mikhail Belkin to discuss his work in machine learning, algorithmic fairness, and artificial intelligence. Kalai has contributed research in areas like fairness in AI models, word embeddings, and human-AI collaboration. He has worked at Microsoft Research and has published influential papers on bias in machine learning models. His work has helped shape discussions on ethical AI and the development of more equitable AI systems. Series: "Data Science Channel" [Science] [Show ID: 40264]

Human beings show a range of emotional attachment, affection, and infatuation often referred to as “love”. Love promotes long-lasting and secure relationships that involve nurturing and support. Biological mechanisms underlying such behavior involve ancient neuropeptides and their receptors in the brain. These systems are also involved in reproduction, ranging from mating and pair-bonding, to giving birth and lactation. They shape the earliest experiences of all mammals and their mothers. The concept of love and how we experience it are affected by culture and its diverse societal norms. This symposium will explore the evolutionary roots of human love, compare human love to corresponding emotions in other animals, consider human conditions that prevent the expression of such feelings, and examine the key role of love and affection for our development and daily lives.  Series: "CARTA - Center for Academic Research and Training in Anthropogeny" [Humanities] [Science] [Show ID: 40506]

Human fathers exhibit hormonal shifts in testosterone, prolactin, and oxytocin, enabling flexible responses to parenting. In species with costly paternal care, these shifts balance mating and parenting efforts, suggesting evolved neuroendocrine capacities that support fatherhood. Today, fathers collaborate with mothers worldwide, though their roles vary across cultures and family systems, much as they likely did evolutionarily. Using research from the Philippines, Congo-Brazzaville, and the U.S., alongside cross-cultural data, this talk examines how men’s hormonal physiology adapts to parenthood and influences family behaviors and bonds within diverse ecological and cultural contexts.

The titi and owl monkeys of South America live in socially-monogamous groups where the male and female establish a pair bond and share parental duties. Why do males of these species mate in a monogamous relationship presumably foregoing other reproductive opportunities? And why are titi and owl monkey males such good fathers, investing heavily in the care of offspring that they cannot be certain they sired? Relying on ecological, behavioral and genetic data collected during 28 years from wild populations in Argentina, Peru and Ecuador. This lecture will discuss the role of food distribution, mate guarding and infant care in the evolution of pair-bonds, monogamy and paternal care.

This film explores the dynamic fusion of science, art and historic collections, set against the stunning backdrop of La Jolla’s hidden underwater world of giant kelp forests. Five artists talks about their unique perspectives captured in the exhibition "Ebb and Flow: Giant Kelp Forests through Art, Science and the Archive," at UC San Diego's Geisel Library. Produced by Mary Ann Beyster, with assistance from filmmaker Eladio Arvelo, the film reveals the profound beauty, healing power and global significance of the vital kelp habitat.

Grandmothers play a key role as alloparents in human families. A leading hypothesis suggests that the inclusive fitness benefits of grandmaternal care selected for an extended female lifespan after reproduction, a unique trait among primates. Beyond lifespan extension, grandmothers may have biological adaptations for caregiving. Research from our lab shows grandmothers have lower DNA methylation of the oxytocin receptor gene (OXTR) compared to non-grandmothers, with lower methylation linked to stronger bonds with grandchildren. MRI scans reveal grandmothers have a lower brain age than controls, further reduced among those with higher engagement. These findings suggest grandmotherhood may enhance oxytocin signaling, promoting bonding and slowing brain aging.

Through a focus on Spanish-speaking Catholics, Amanda Baugh sheds light on environmental actors hiding in plain sight. Drawing from ethnographic research conducted across Los Angeles, Baugh, Professor and Associate Chair of Religious Studies and Director of the MA Program in Sustainability at California State University, Northridge, demonstrates that minority communities are not merely victims of environmental problems. Instead, many Spanish-speaking Catholics embrace what Baugh calls “la tierra environmentalism,” an embodied ethic of living lightly on the Earth that is rooted in a sense of love and respect for God, fellow humans, and the rest of God’s creation. A focus on la tierra environmentalism challenges scholars and activists to rethink who counts as environmental leaders and what counts as environmentalism.

Close relationships help us shape both our other social interactions as well as our internal physiology. Do these close relationships, also known as pair bonds, look and function similarly in species as diverse as titi monkeys, prairie voles, seahorses, and humans? How do negative experiences such as loss factor into, and perhaps strengthen, our close relationships? And what do we mean by luminance? This lecture will explore these topics while also touching on the underlying neurobiology of pair bonding.

Ths discussion captures the experiences of parents raising neurodivergent children, emphasizing the importance of finding joy, fostering inclusion, and supporting sibling relationships. Parents share personal stories of resilience, from guiding neurotypical siblings to embrace their roles with love to advocating for inclusive school environments. They highlight the unexpected ways their children teach them patience and strength, as well as the deep sense of community that emerges when families, educators, and peers come together.
