127: Coffee Intake and the Microbiota–Gut–Brain Axis

This episode dissects a research study that investigates the microbiota-gut-brain axis by comparing coffee drinkers to non-drinkers and observing the effects of caffeine withdrawal and reintroduction.

126: Peakspan: Defining and Extending the Boundaries of Human Performance

This episode does a deep dive into an academic perspective that introduces Peakspan, a novel metric defined as the period when an individual maintains at least 90% of their maximum functional capacity in specific physiological or cognitive areas. The authors argue that while humans are living longer, most biological systems—including cardiorespiratory, renal, and immune functions—peak in early adulthood, creating a significant "functional gap" where people are clinically healthy but significantly declined. This misalignment poses a major threat to economic productivity and the sustainability of retirement systems as the "Biological Retirement Age" approaches earlier than the chronological one.

125: Sleep Chart of Biological Ageing Clocks Across Systems

This episode does a deep dive into a 2026 study by the MULTI Consortium that identifies a systemic, U-shaped relationship between sleep duration and biological ageing across the human body. By analyzing data from the UK Biobank, researchers utilized 23 biological ageing clocks derived from MRI imaging, plasma proteomics, and metabolomics to show that both insufficient and excessive sleep accelerate ageing in nine organ systems.

124: Neural Recovery After Carpal Tunnel Release: A Systematic Meta-Analysis

This episode dissects a comprehensive systematic review and meta-analysis regarding the recovery of the median nerve after carpal tunnel release surgery. Spanning 199 studies and over 15,000 patients, the research investigates structural and functional healing through metrics like nerve conduction, sensory testing, and grip strength.

123: Creatine Supplementation in the Management of Osteosarcopenia

This episode examines the potential of creatine monohydrate as a therapeutic tool for managing osteosarcopenia, an age-related decline in both bone density and muscle mass.
