Examine how what we eat and how we live can promote wellness, enhance immunity, combat age-related diseases, and promote longevity. Gordon Saxe, M.D., Ph.D., and Anthony Lim, M.D., J.D., share a timeless perspective, supported by their own research and clinical experience, on how optimal nourishment, purposeful reflection, health movement, and generosity of spirit can improve age-related conditions and slow the aging process. They present evidence-based recommendations for diet and lifestyle, as well as a practical and simple framework to help foster extending healthy aging behavioral changes.

John Dick, Ph.D., F.R.S., explores the role of CD83, a molecule found in blood stem cells, in how these cells respond to inflammation. His team demonstrates that CD83 becomes highly active during inflammation and contributes to the loss of healthy stem cells. Using advanced gene-editing tools, they show that removing CD83 protects stem cells from inflammation-related damage. This discovery highlights CD83 as a potential marker for identifying inflamed stem cells and as a possible target for treatments to improve recovery after stem cell transplants. He also discusses early findings on potential differences in blood stem cell behavior between men and women and raises questions about how inflammation from severe illnesses, like COVID-19, could impact the blood system as we age.

How can a healthy microbiome prevent disease? In this program, Dr. Sean Spencer talks about the vast microbial world that lives within our guts — known as the gut microbiome — and how it supports our health. He discusses the current evidence about how to nourish your microbiome to prevent and treat disease.

Catriona Jamieson, M.D., Ph.D., discusses pioneering research on cancer and aging in space environments, highlighting how microgravity accelerates cancer cell growth and leads to stem cell exhaustion, genomic instability, and “dark genome” activation. Using innovative tools like nano-bioreactors and artificial intelligence, her team simulates these effects and tracks cellular changes, uncovering how space’s unique conditions drive mutations and alter cellular behavior. They find that stem cells rapidly proliferate but then become exhausted in space, a process tied to telomere shortening and mitochondrial stress, impacting cell longevity and regenerative potential. Through collaborations with NASA and industry partners, Jamieson’s research aims to develop therapies to counter these effects, offering potential insights for cancer treatment and stem cell health on Earth.

Through the UniversityLink Medical Science Program (ULMSP), college students from underrepresented and disadvantaged backgrounds who aspire to become future health science professionals develop essential academic and professional skills, benefit from long-term mentoring, and build lasting social and professional networks. Dr. Ramón A. Hernandez highlights how the program fosters family support, instills a culture of academic excellence, and emphasizes the importance of community service, showing how ULMSP helps pave the way for these students' success in the health sciences.

What's the secret to supporting a sharp mind at any age? In this program, Dr. Nancy Isenberg discusses the latest science-based practices to promote brain health and resiliency as we age. Series: "Osher WISE: Well-being and Integrative Science for Everyone" [Health and Medicine] [Show ID: 40073]

Elizabeth Blackburn, Ph.D., examines the relationship between telomeres, cellular aging, and metabolic health, highlighting how telomere regulation differs between insulin-sensitive and insulin-resistant individuals. She discusses the effects of environmental factors—like glucose levels, stress hormones, and drugs—on telomere maintenance, which can disrupt cellular coordination and contribute to age-related diseases. Blackburn also shares insights from studies on hibernating lemurs, indicating that while their telomere health remains stable during metabolic slowdowns, it declines upon reactivation. Ultimately, she suggests that telomere maintenance could serve as a valuable biomarker for early signs of metabolic dysfunction, informing strategies for long-term health and resilience.

Dennis O. Clegg, Ph.D., discusses treatments for age-related macular degeneration (AMD), a condition that causes vision loss. Clegg explains that while patients often report improved vision after receiving implants, objective tests don't always confirm this. He explores the potential differences in patients' responses based on genetics and disease progression. There is also an ongoing challenge in finding the best ways to reduce immune rejection of these treatments. New trials are underway to test implants in earlier stages of the disease, and researchers are looking at different strategies like localized immunosuppression. Additionally, some studies suggest that secretions from retinal cells may help preserve vision. Overall, there are many open questions, but advances in the field offer hope for better AMD treatments.

In the last ten years, we've seen a huge change in our approach to epilepsy surgery. We have more options than ever before for patients with uncontrolled seizures. In this new video, @UCSFHospitals neurosurgeon Edward Chang, MD, provides an overview of the pros and cons of different minimally invasive surgical treatments: laser ablation, responsive neurostimulation, deep brain stimulation and vagal nerve stimulation.

We hope that raising awareness about the available options can help more people access effective therapies and eliminate or greatly reduce their seizures. Series: "UC San Francisco News" [Health and Medicine] [Show ID: 40239]

The risk for many chronic diseases is directly linked to metabolic changes in the body and loss of muscle mass often associated with aging. In this program, Dr. Natalie Marshall focuses on the central importance of movement, strength training, and body composition to improve metabolic fitness and tips to help you get started “building muscle for life."
