Michael J. Wilkinson, M.D., F.A.C.C., F.N.L.A., explains how aligning when we eat, sleep, and move with our body’s natural circadian rhythms can profoundly affect metabolic health. Drawing on research from UC San Diego and the Salk Institute, he explores how disruptions in daily patterns—late-night eating, less movement, artificial light—contribute to obesity, diabetes, and fatty liver disease. Wilkinson shows why *when* we eat may be as important as *what* or *how much* we eat, and how time-restricted eating offers a practical, biology-based strategy for preventing cardiometabolic disease and promoting healthy aging.

In Vivo Brain Organoid Model to Study Human Neuronal-glia Interactions
An in vivo brain organoid platform reveals how human neurons and glia interact across development, aging, and disease. Fred H. Gage, Ph.D., generates three dimensional organoids from induced pluripotent stem cells and examines their maturation, synapses, and network activity with two-photon imaging and single-cell profiling. Gage integrates human microglia and astrocytes to study immune signaling, injury responses, and support functions that shape circuit behavior. Transplantation enables vascularization, reduces cell death, and yields features consistent with a blood brain barrier. Analyses identify diverse astrocyte types and trajectories, while patterns of tau expression inform Alzheimer’s disease modeling. Gage also converts adult fibroblasts into age retaining neurons that assemble into 3D spheroids, creating complementary models to connect genes, cells, and circuits with pathology and to guide strategies for prevention and therapy.

Dealing with Difficult People
If you feel like there's more rudeness in the world, you're not alone. According to John O'Brien, psychologist and author of "Rudeness Rehab," there's a pandemic of incivility. O'Brien says we're seeing bad behavior everywhere, from the streets to the workplace to even the operating room. As part of our Osher Author Talk series, host Henry DeVries talks with O'Brien about the physical and mental toll of experiencing rudeness. O'Brien says we have the power to be our own superhero when dealing rude and difficult people. He calls his approach BAM, which stands for breathing, active listening and mindfulness.
