Modern humans are living in an environment radically different from the one our biology evolved to operate within. In this conversation, we explore how light, mitochondria, evolution, and physics shape aging, disease, mental health, and longevi...

We discuss three pivotal studies showing how natural light wavelengths positively influence health from all-cause mortality to visual perfomance to blood glucose control in Type II diabetics.Jonathan Jarecki is a biomedical science soph...

Peter Cowan and I discuss the surge in non-contact soft-tissue injuries of 49ers players and possible mechanisms including chronic magnetic field exposure from nearby electrical substation, circadian rhythm disruption causing mitochondrial dysf...

Sunlight or fake light? We explore how light timing and intensity shape the circadian clock, mood, hormones, fertility, and sleep—and why amplitude is the missing key. Sean Kane shares new research on individual light sensitivity, depression an...

In this talk I present the case that artificial light and wireless RF radiation are pervasive indoor pollutants that are disrupting your circadian rhythm and damaging the health of your children. Watch on Youtube to see the slides.&...
