    Mapping Cognitive Resilience: How Environment Aging and Inflammation Shape Information Encoding in the Hippocampus

    Cognitive resilience depends on how the brain responds to environment, aging, and inflammation. J. Tiago Gonçalves, Ph.D., studies the hippocampus to examine how spatial memory is shaped by factors such as cognitive enrichment, exercise, social interaction, disease, and age. Gonçalves explains how adult neurogenesis and microglia help support the brain’s ability to encode information, and how disruptions in these systems can affect memory. He also shows that aging and systemic inflammation can weaken spatial encoding while still revealing signs of adaptation and recovery over time. By connecting brain plasticity, immune activity, and memory formation, Gonçalves presents a broader view of how cognition changes across the lifespan and how these mechanisms may inform future strategies for addressing cognitive decline Series: "Stem Cell Channel" [Health and Medicine] [Science] [Show ID: 40848]

    Learning Beyond the Data: Adam Klivans on Distribution Shift and the Future of AI

    Trustworthy machine learning requires models that still work when real-world data changes, and Adam Klivans, Ph.D., Director of the Institute for Foundations of Machine Learning (IFML), emphasizes learning under “distribution shift” as a major barrier to relying on models to predict disease across different patient populations. IFML focuses on foundational algorithms and mathematical techniques that push generative AI forward, including better methods for training and inference in deep learning and advances in diffusion approaches. Klivans highlights robustness and safety as core priorities, asking how to trust a model trained in one setting when it is applied in another. IFML connects these foundations to use-inspired domains such as imaging, protein engineering and biologics, and AI for mathematical discovery. Series: "Science Like Me +" [Science] [Show ID: 40972]

    Where Innovation Meets Patients: The Work of California’s Alpha Clinics

    Alpha Clinics in California accelerate the development of regenerative medicine therapies that use cells and genes to treat serious diseases. Patient advocate Tara Radcliffe Ghiglieri shares lived experience with gene therapy, while Sheldon Morris, M.D., M.P.H., Mehrdad Abedi, M.D., Daniela A. Bota, M.D., Ph.D., Catriona Jamieson, M.D., Ph.D., Michael Lewis, M.D., Mark Walters, M.D., and Leo D. Wang, M.D., Ph.D., describe how Alpha Clinic teams design and deliver clinical trials for a wide range of conditions, including cancer, blood disorders, neurologic disease, osteoarthritis, metabolic disorders, pulmonary arterial hypertension, and Duchenne muscular dystrophy. They highlight how coordinated networks, community partnerships, and genomic tools help expand access, lower financial barriers, and bring promising cell and gene therapies to more patients while carefully tracking safety, effectiveness, and long-term outcomes.

    CARTA: The Evolution of the Human Brain through Shifts in Gene Regulation with Miles Wilkinson

    A fundamental question in biology is: how did humans acquire their unique characteristics? What allows us to stand upright, while our primate ancestors walked on all fours? What brain alterations drove our increased intelligence and allowed us to perceive our own mortality? One of the mechanisms that has been hypothesized to be involved is changes in gene expression elicited by nucleotide alterations in non-coding regions of the human genome. Miles Wilkinson, a professor in the Department of Obstetrics, Gynecology, and Reproductive Sciences at UC, San Diego, discusses a class of DNA sequences hypothesized to have this role. These human accelerated regions (HARs) are segments of DNA that exhibit 3 characteristics that—together—make them prime candidates for specifying human-specific traits by altering patterns of gene expression. First, HARs have rapidly changed in sequence specifically in the human lineage. Second, HARs are highly conserved in sequence, indicating they that must have been selected for the ability to confer one or more function in higher organisms. Third, the vast majority of HARs are in the non-coding portion of animal genomes, indicating that most are likely to have a regulatory function.

    Reimagining T Cell Therapy: An Unconventional Path to Universal CAR-T Cells

    Off-the-shelf immune cell therapies using engineered T cells represent an important direction in cancer treatment. Lili Yang, Ph.D., at UCLA develops an off-the-shelf platform based on invariant natural killer T (iNKT) cells generated from hematopoietic stem cells, often sourced from cord blood. Yang programs these stem cells with iNKT cell receptors, chimeric antigen receptors (CARs), and genes such as IL-15 to create pure, expandable iNKT products that recognize lipid antigens presented by non polymorphic CD1d molecules. These cells combine multiple killing mechanisms, infiltrate tissues, target tumor cells and immunosuppressive myeloid cells, and show reduced risk of graft versus host disease and cytokine release syndrome in preclinical models. Yang’s group tests this strategy in models of blood cancers and solid tumors, aiming to generate many therapeutic doses from a single donor.

    CARTA: Human Brain Specializations Related to Language and Theory of Mind with James Rilling

    Humans excel at transmitting ideas, skills, and knowledge across generations, and at building on those competencies in a cumulative manner. James Rilling, Professor of Psychology at Emory University, explores how the transmission of our cumulative culture is assumed to depend on both language and mental perspective-taking, or theory of mind. If humans have specialized abilities in these domains, we must have neurobiological specializations to support them. Our research has used comparative primate neuroimaging to attempt to identify such specializations. The arcuate fasciculus is a white matter fiber tract that links Wernicke’s and Broca’s language areas. It is known to be involved in multiple, high level linguistic functions such as lexical semantics, complex syntax, and speech fluency. Using diffusion weighted imaging and tractography, we have demonstrated human specializations in the size and trajectory of the arcuate fasciculus that may partially explain human linguistic abilities. Theory of Mind depends on a set of cortical regions that belong to a neural network known as the default mode network that is functionally connected, highly active at rest, and deactivated by attention-demanding cognitive tasks. We and others have used functional neuroimaging to show that chimpanzees and other primates appear to have a default mode network that is similar to that of humans. However, the non-human primate default mode network seems to have weaker connectivity between certain key nodes, suggesting that these connections could play a role in human theory of mind specializations.
