  • CARTA: The Costs of Big Brains with Alex Pollen

    CARTA: The Costs of Big Brains with Alex Pollen
    Apr 15 2026
    Human brain expansion is often discussed in terms of the genetic and molecular innovations that drove uniquely human cognitive abilities. Yet evolution is fundamentally a process of tradeoffs. Disproportionate expansion of forebrain structures increases the demands placed on long-range connectivity, metabolism, and cellular maintenance, imposing costs that scale with brain size. Alex Pollen, associate professor of neurology at UC San Francisco, discusses using stem-cell-derived brain organoids to investigate the development of human-specific connectivity differences in dopaminergic neurons and to test whether these cells deploy compensatory mechanisms to cope with the metabolic and structural demands of large brains. His research findings support a model in which human brain evolution involves not only mechanisms driving greater computational capacity, but also the emergence of cellular adaptations that mitigate the costs of large, highly connected brains.

    A Conversation with Jamaica Kincaid - Writer's Symposium By the Sea 2026
    Apr 13 2026
    Jamaica Kincaid is an Antiguan-American writer known for her vivid, poetic prose and exploration of themes like colonialism, family, identity, and the legacy of the Caribbean. Her deeply personal and reflective style has made her one of the most influential voices in contemporary literature. Born Elaine Potter Richardson on May 25, 1949, in St. John’s, Antigua, she moved to the United States as a teenager and began her career writing for The New Yorker. Her acclaimed works include Annie John, Lucy, A Small Place, and The Autobiography of My Mother. Kincaid joins host Dean Nelson for a lively and funny conversation at Point Loma Nazarene University.

  • Artificial Intelligence in (AI-Driven) Healthcare

    Artificial Intelligence in (AI-Driven) Healthcare
    Apr 13 2026
    AI in healthcare raises urgent questions about bias, privacy, and power. Safiya U. Noble, Ph.D., examines how AI systems can reproduce social and racial inequities when they rely on incomplete data, hidden assumptions, and proxies such as healthcare spending. Noble points to problems in search engines, image generation, facial recognition, and medical algorithms, including cases where systems mislabel darker skin, fail more often on Black women, or favor white patients over sicker Black patients. She also highlights the risks of turning sensitive public and patient data over to large technology companies. Rather than treating AI as a neutral solution, Noble emphasizes the need for human judgment, community participation, stronger data protections, and smaller expert models with local control so healthcare decisions better reflect people’s real lives and social context.
