In this episode, we unpack a groundbreaking 2024 study from the Journal of Biophotonics showing that just 15 minutes of 670 nm red light exposure—targeting the upper back before a glucose challenge—led to a 27.7% reduction in overall post-meal blood sugar levels and up to 12% lower glucose spikes compared to placebo

We explore how this light stimulates your mitochondria to make more ATP, prompting your body to burn more glucose, and possibly triggering systemic signals that help regulate metabolism

Think: a smart, non-invasive way to curb sugar surges and protect against long-term health risks.

Tune in to learn the science, real-world implications, and whether this red-light method could one day support diabetes management or everyday metabolic health.

What if part of what makes us human comes from an ancient virus? In this episode, we explore groundbreaking research revealing how retroviral DNA—once thought to be genetic junk—played a critical role in the evolution of myelin. Myelin, the protective sheath around nerve fibers, supercharged the speed of nerve signals and made complex vertebrate brains possible. Scientists have now discovered a specific genetic element, called RetroMyelin, embedded in our DNA by a virus hundreds of millions of years ago.

This viral legacy appears not only in humans but across species—from fish to mammals—suggesting it was a pivotal evolutionary leap. Without this ancient genetic hitchhiker, the rapid, efficient brain communication we take for granted might never have evolved.

Join us as we break down what myelin is, how this discovery reshapes our understanding of brain evolution, and why viruses might be more deeply woven into the story of life than we ever imagined. Whether you’re into neuroscience, genetics, or just love a good twist in the history of evolution, this episode delivers a mind-expanding journey through time, science, and the surprising ways the past still lives inside us.

In this episode, we dive into a groundbreaking BMJ study of nearly 60 million U.S. Medicare beneficiaries, revealing how long-term exposure to fine particulate matter (PM₂.₅) increases hospital admission risks for heart diseases—even at low levels. Discover how chronic PM₂.₅ exposure raises rates of ischemic heart disease, stroke, heart failure, arrhythmia, and aneurysms, with no safe threshold, as risks emerge even from 5 μg/m³—well below many current regulatory levels

Learn about the study’s innovative use of causal frameworks and exposure calibration techniques that sharpen our understanding of air pollution’s true impact. We also unpack how the World Health Organization's guideline of ≤ 5 μg/m³ can deliver substantial cardiovascular benefits—yet many U.S. standards may still fall short

Plus, hear how factors like age, education level, neighborhood deprivation, and access to healthcare amplify vulnerability to PM₂.₅—underscoring environmental justice implications
