How do you navigate a nonlinear, “squiggly line” career in science and public health? Dr. Katelyn Jetelina, an epidemiologist and scientific communicator, explores challenges of science communication within academia—from cultural resistance to misaligned incentives—and why so much vital research never reaches the public. Joined by Dr. John Schwartzberg, Professor Emeritus, School of Public...

Exercise is medicine, however, is there an optimal time to take that medicine? Satchidananda Panda, Ph.D., Salk Institute, discusses the benefits and hazards of exercising, depending on the time of day. Series: "Stein Institute for Research on Aging" [Health and Medicine] [Show ID: 41209]

Circadian timing shapes how we sleep, feel, and function each day. Satchidananda Panda, Ph.D., Salk Institute, describes what the ideal circadian rhythms of a day look like. Dr. Panda explains that keeping daily light, meals, movement, and sleep in step with the body’s internal clock supports alertness, metabolism, and recovery. Series: "Stein Institute for Research on Aging" [Health and...

Rudeness is not just annoying. John O’Brien, psychologist and author of "Rudeness Rehab," links everyday rudeness to stress and even broader health outcomes, including differences in life expectancy.

How much exposure to daylight is recommended for optimal health? Satchidananda Panda, Ph.D., Salk Institute, answers this question and many more on the therapeutic nature of light. Dr. Panda also discusses indoor lighting considerations in order to simulate day/night cycles. Dr. Panda explains that the use of lighting isn't just for safety and convenience but also for one's health. Series: "Stein...

In this excerpt, Dr. Natalie Marshall responds to a question about taking nutritional supplements. Dr. Marshall speaks on the importance of getting vitamins through natural foods. Series: "Osher WISE: Well-being and Integrative Science for Everyone" [Health and Medicine] [Show ID: 41185]

Public health often works behind the scenes—preventing illness, protecting communities, and generating research that too often stays hidden behind paywalls. In a world of eroding trust and rising falsehoods, Dr. Katelyn Jetelina, an epidemiologist and scientific communicator, explores how we can make the value of public health visible: by telling better stories with data, making science more...

Intermittent fasting isn’t just about calories—it’s about timing. Michael J. Wilkinson, M.D., F.A.C.C., F.N.L.A., explains how time-restricted eating aligns daily food intake with the body’s natural circadian rhythms. He shares insights from animal studies, clinical trials, and UC San Diego research showing how consolidating meals into an 8–10 hour window can improve glucose control, blood...

Biological resilience underpins healthy aging, and Anthony Molina, Ph.D., investigates how people resist, adapt to, and recover from age-related stressors. Molina defines three domains of resilience linked to aging and studies “life course” resilience using the Rancho Bernardo Study, a longitudinal cohort that starts in 1972 and tracks cognitive, sensory, physical function and comorbidities. His...

Alejandro Sánchez Alvarado, Ph.D., argues that real progress in understanding regeneration comes from studying whole organisms rather than cells grown under artificial conditions. Sánchez Alvarado shows how observations from intact animals reveal organizing rules that narrow laboratory systems can miss. He presents evidence that stem cells in a studied animal lack detectable junctions with...
