Is sacred space protective space? This question lies at the heart of the Sanctuary Movement. From the 1980s to the present, this practice has protected undocumented immigrants at risk of deportation by offering them refuge in churches, where federal immigration agents to this day still fear to tread. In this lecture, Lloyd Barba, Assistant Professor of Religion and Core Faculty in Latinx and Latin American Studies at Amherst College, asks how these houses of worship in the 1980s protected migrants from immigration enforcement authorities. What histories and testimonies rendered such spaces sacred and lent houses of worship qualities of safe refuge? And what is the applicability of these practices today?

UCLA’s Avishek Adhikari, PhD, presents new research on the role of GABAergic neurons in the brain’s periaqueductal gray (PAG) region. Previously studied for their involvement in fear and defensive behaviors, these neurons were found to promote food-seeking behavior when activated—even in fully fed mice. Using calcium imaging and optogenetics, Adhikari’s team discovered that these neurons are active during food approach but suppressed during eating. The effect is stronger for high-value foods like chocolate or crickets and depends on the mouse’s prior experience with that food. A key finding is that these neurons influence behavior through a specific projection to the zona incerta, a subthalamic region. Rather than signaling hunger, this pathway appears to drive food seeking based on reward value, highlighting a new motivational circuit in the brain.

Take a stunning journey across Earth as seen from space, captured by the astronauts of ISS 69 on July 30, 2023. This film soars over the Greek islands, Turkey’s rolling mountains, cloud-covered Ukraine, the Volga River flowing into the Caspian Sea, and a glowing sunset over Mongolia. The breathtaking visuals are set to music by Steve Thomas Guitar, featuring tracks adapted from his Folktales and Fusions album, with performances by Chris Cheek (alto sax), Rosie Caine (harp), Josh Metz (bass), and Claire Arenius (percussion).

Sheng Zhong, Ph.D. pioneers technologies that advance women’s reproductive health. Zhong develops a minimally invasive method to analyze extracellular RNA secreted by embryos during IVF. By sequencing tiny samples of spent culture media, they generate comprehensive RNA profiles and use machine learning to identify biomarkers that predict embryo quality with accuracy comparable to traditional imaging. This breakthrough offers a gentler, data-driven alternative for assessing embryo viability, with the potential to improve live birth rates and support families navigating infertility. Zhong’s research highlights the power of molecular innovation to transform fertility care and address critical challenges in women’s health.

The land we now call Scripps Oceanography has been home to the Kumeyaay people for thousands of years. A history of encroachment, colonization and displacement from coastal lands has challenged Kumeyaay ocean traditions and practices. Today, Kumeyaay-Iipay-Tipay people are actively revitalizing Indigenous ocean culture. As part of Perspectives on Ocean Science Lecture Series, Stan Rodriguez and Priscilla Ortiz Sawah of the Iipay Nation of Santa Ysabel, and Andrew James Pittman of the Los Coyotes Band and Cupeño Indians, talk about the history of the Kumeyaay culture in the region. Through community efforts, they are rebuilding traditional ha kwaiyo (tule boats), harvesting ha shupill (grunion) and teaching language about the ocean (ha silowik). These intergenerational practices embody Indigenous resilience, resistance and revival — nurturing and evolving Indigenous ocean knowledge, culture and traditions. Series: "Jeffrey B.

Linda Brubaker, M.D. emphasizes the urgent need to advance women’s health research beyond its traditional focus on reproduction, pregnancy, menopause, and breast cancer. She highlights the biological, social, and lifestyle factors that affect women across the lifespan and calls for greater inclusion of women in clinical research. Brubaker announces her leadership of a new JAMA initiative to centralize women’s health content and promote rigorous scientific studies. She stresses that conditions like menopause and aging impact all areas of medicine and should be understood by all clinicians. Brubaker encourages collaboration, innovation, and resilience in pursuing high-quality science to support personalized care, healthy aging, and improved outcomes for all women.

Andrea Z. LaCroix, Ph.D. presents major public health trends affecting women across the lifespan, from rising maternal mortality and chronic disease risks linked to pregnancy complications to the ongoing need for improved menopause care. She highlights innovative research, including digital tools for menopause education, studies on cancer survivorship, and efforts to predict healthy aging using epigenetic clocks and physical activity data. LaCroix shows how decades of research continue to shape strategies for aging with preserved cognitive and physical function, aiming to help more women thrive into their 90s and beyond.

Dr. Kelly Fitzgerald explains current standards of care for metastatic hormone-sensitive prostate cancer, focusing on treatment strategies shaped by both clinical trial data and emerging imaging technologies. She defines key terms such as poly- and oligometastatic disease and outlines how newer imaging methods like PSMA PET scans are reshaping diagnosis. She describes the shift from traditional androgen deprivation therapy (ADT) to intensified ADT, where additional agents—such as chemotherapy or novel hormone therapies—are shown to improve survival. Fitzgerald also reviews ongoing questions around triplet therapy and the potential benefits of local treatments like radiation. She highlights the importance of patient-specific factors and the evolving definitions that influence treatment decisions in this complex disease landscape.

Antoni J. Duleba, M.D. outlines the broad scope of reproductive endocrinology and infertility, emphasizing care across a woman’s lifespan—from adolescence through menopause. He explains common endocrine conditions like polycystic ovary syndrome (PCOS), endometriosis, and menstrual disorders, all of which can affect fertility and overall health. Duleba highlights advances in fertility preservation, especially for patients undergoing cancer treatment, and notes the rising need for such services as more women delay childbearing. He also addresses efforts to improve hormonal therapies, IVF outcomes, and treatments that target inflammation and the microbiome. In addition to medical innovation, he points to social and financial barriers that continue to limit access to reproductive care. Series: "Motherhood Channel" [Health and Medicine] [Show ID: 40672]
