In this episode, we explore how ketamine, a dissociative anesthetic with a long history in medical use, is now being investigated for its rapid and sustained effects on depression, anxiety, and PTSD. We discuss its role in promoting neuroplasticity—rewiring the brain's structure to counteract stress-induced atrophy—and review the evidence from clinical trials, including a landmark 2023 meta-analysis. While ketamine shows promise in alleviating depressive symptoms and supporting neural growth, we also address its risks and the importance of professional oversight. Learn how this cutting-edge research is reshaping mental health treatment and what it means for the future of therapy.

In this episode, we talk about a recent study from Nature Aging that suggests aging may not progress in a straight line. Using data from thousands of biological measurements, researchers identified key ages—44 and 60—where changes in aging appear to accelerate. We review what this means for our understanding of aging, how it affects multiple systems in the body, and the potential implications for health and disease. We also discuss what this study tells us—and doesn’t tell us—about the biology of aging and how it could guide future research.

Can we slow the speed of aging? In this episode, Dr. Varun Dwaraka, Head of Bioinformatics at TruDiagnostic, walks us through through the science of measuring "biological age" using epigenetic markers, such as DNA methylation. We discuss how epigenetics (i.e. DNA methylation), may provide biomarkers of biological age, the rate at which aging occurs, and potentially early markers of disease. Dr. Dwaraka explains the distinctions between chronological and biological age, the development and refinement of epigenetic clocks, and the potential applications of these tools in aging interventions. The conversation also addresses the mechanisms of epigenetic regulation, the influence of lifestyle factors on biological age, and the future role of epigenetics in predicting and managing age-related diseases. Additionally, we examine the data science that underpins these clocks, their targeted outcomes, and a recent study published by Dr. Dwaraka and colleagues comparing aging biomarker outcomes in a vegan vs. omnivore diet intervention among twins.
