![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. [Show ID: 40972]

![How Can Primary Care Detect Alzheimer’s Risk Earlier?
A version of this video with audio description track is available here:
https://www.youtube.com/watch?v=B6L19pWzHBA
Alzheimer’s disease can begin developing years before memory and thinking problems become noticeable. Iris Broce-Diaz, Ph.D., of UC San Diego is developing accessible, noninvasive, and cost-effective tools to help primary care physicians and neurologists identify people at higher risk earlier. Her models combine information from cognitive assessments, brain imaging, genetics, and PET scans to estimate the likelihood that mild cognitive impairment will progress within five years. Combining multiple measures improves the models’ ability to separate higher- and lower-risk patients. Broce-Diaz also plans to add women-specific factors, including menopause history, hormone therapy, reproductive history, endocrine markers, and symptoms. The goal is to support better referrals, guide monitoring, and help eligible patients consider treatment sooner. Earlier risk assessment could also strengthen clinical trials and make dementia care more useful across different health systems. Recorded on 05/27/2026. [8/2026] [Show ID: 41632]

FAQ
Q: How early can Alzheimer’s disease begin before symptoms appear?
A: The disease process can begin about 10 years before noticeable memory or thinking problems. This makes earlier risk assessment important for monitoring, referrals, and treatment decisions.
Q: How can doctors estimate whether mild cognitive impairment will progress?
A: Risk models can combine cognitive assessments, brain imaging, genetics, and PET scans. In the data presented, combining several measures separates people at higher and lower risk more effectively than using one measure alone.
Q: Why include menopause and reproductive health in Alzheimer’s risk models?
A: Alzheimer’s disease affects women about twice as often as men, and biological changes may occur during the same period when the disease is beginning to develop. Researchers are studying menopause history, hormone therapy, reproductive history, endocrine markers, and symptoms to see whether they improve prediction for women.

![Treatment for Moyamoya Disease
UCSF stroke neurologist Dr. Anirudh Sreekrishnan and UCSF vascular neurosurgeon Dr. Luis Savastano describe Moyamoya disease, a rare condition where arteries at the base of the brain become narrowed or blocked, reducing blood flow. The name “moyamoya” means “puff of smoke” in Japanese, describing the tiny vessels that form to compensate. These fragile vessels can cause strokes or bleeding. Treatment often involves surgical procedures, such as direct or indirect revascularization, to restore blood flow and reduce stroke risk. [9/2025] [Show ID: 41036]

![The Causes of Autism
A version of this video with audio description track is available here:
https://www.youtube.com/watch?v=P5ST1nY6o0A
Understanding the causes of autism matters for families, public health, and public trust in science. Jonathan Sebat, Ph.D., UC San Diego, explains what research actually shows about the causes of autism and how scientists separate strong evidence from misleading correlations. Sebat examines genetics, de novo mutations, twin studies, developmental regression, and the interplay of genes and environment, helping clarify why autism cannot be reduced to a single trigger. He also addresses why rising diagnoses do not necessarily reflect a simple rise in symptoms and why better research design is essential when studying environmental influences. This work helps explain what science does and does not support and points toward a more rigorous understanding of autism. Recorded on 11/07/2025. [6/2026] [Show ID: 41177]

![Glycobiology (GLOW)
Amanda Lewis, Ph.D. investigates how glycan-degrading enzymes contribute to bacterial vaginosis (BV), a common condition linked to infertility, preterm birth, pelvic inflammatory disease, and increased cancer risk. Her research shows that BV-associated bacteria strip protective sugar coatings—glycans—from vaginal epithelial cells, disrupting normal function and increasing vulnerability to infection. Lewis and her team study specific enzymes, such as sialidases, that remove sialic acid from glycoproteins and mucins. Using clinical samples and imaging techniques, they identify how these changes in glycan composition correlate with disease severity. Their work reveals how glycan degradation contributes to persistent or recurrent BV and opens new pathways for understanding the microbiomes role in women’s health. Recorded on 04/16/2025.

![Germline Epigenetic Imprints Regulate Mammalian Development with Azim Surani
Azim Surani, Director of Research at the Gurdon Institute and Professor Emeritus at University of Cambridge, received the Kyoto Prize in Basic Sciences, specifically in the field of Life Sciences and Medicine, for his work in demonstrating how male and female mammalian genomes receive distinct imprints during germ cell development. Genomic imprinting introduced a novel concept to Mendelian genetics and is a now fundamental principle in the life sciences. Suranis research has contributed to developmental biology and epigenetics, along with a wide range of life science fields including physiology, regenerative medicine, reproductive medicine, and plant science.

![Returning to the Moon
A version of this video with audio description track is available here:
https://www.youtube.com/watch?v=AyBexB_oPJk
With the success of Artemis II, NASA is preparing for humanity’s return to the Moon through the ambitious Artemis Project. In this lecture, Professor Neil Farber explores the future Artemis missions, the spacecraft and technologies designed to support them, and the challenges NASA faces in sending astronauts back to the lunar surface. Building on the legacy of the Apollo program, Artemis represents a new era of exploration focused not only on reaching the Moon, but on establishing a sustainable long-term presence and preparing for future missions to Mars. Professor Farber examines why returning to the Moon today presents more difficulties than during the Apollo era, including modern engineering demands, funding realities, mission complexity, astronaut safety, and the logistical challenges of deep space travel. The lecture also highlights how NASA’s goals have evolved since Apollo and why the Moon remains central to the future of human space exploration. Recorded on 05/13/2026. [Show ID: 41597]
