How Screens Rewire Childhood: The Science Behind Smartphones, Social Media, and Child Development

Biologist and science journalist Irina Yakutenko examines the scientific evidence behind smartphone and social media bans for children, unpacking research on lost language development, displaced boredom and free play, dopamine-driven attention deficits, and "technoference" between parents and kids. Drawing parallels to the sugar industry's manipulation of nutrition science, she argues that consistently directional findings across imperfect studies still reveal real harm—despite methodological limitations like reverse causality and self-report bias. The discussion covers screen effects on vocabulary acquisition, executive function, shared reading, physical activity, and parental phone habits, closing with a preview of upcoming topics like sleep, eyesight, and practical recommendations for families.

Creatine Uncovered: Debunking Myths and Exploring Muscle, Bone, and Brain Benefits with Dr. Darren Candow

Creatine researcher Dr. Darren Candow separates fact from fiction, debunking persistent myths about kidney damage, water retention, hair loss, and cramping while explaining the science behind creatine's real benefits for muscle performance, bone density, and brain function under stress. He covers practical dosing strategies for different goals—from 3-5g for muscle to 8-12g for bone health to 20-30g for cognitive resilience during sleep deprivation—along with product quality tips, microdosing techniques, and emerging research on Alzheimer's, depression, and concussion recovery. The conversation also touches on aging, menopause, protein synergy, and Candow's personal supplement routine, framing creatine as one essential tool within a broader lifelong health toolbox.

Why Your Metabolism Isn't the Problem: The Science and Psychology of Losing Weight

This deep dive dismantles the myths of "slow metabolism" and magic slimming foods, explaining what actually governs weight gain — calorie arithmetic, muscle mass, genetics of appetite, and an evolutionary brain built for scarcity. It covers the science behind semaglutide (Ozempic), why crash diets can permanently lower your basal metabolic rate, and how the body fights back against a deficit by cutting your activity and cranking up your cravings. The second half turns to psychology: the constant battle between the rational prefrontal cortex and the pleasure-driven limbic system, and why willpower alone reliably loses. Practical takeaways include honest calorie tracking, removing temptation from physical reach, and engineering "controlled external compulsion" — trainers, groups, commitments — so circumstances, not willpower, make your decisions for you.

The Burden of the Past in Our Brain: How a Billion Years of Evolution Still Runs Your Mind

Anthropologist Stanislav Drobyshevsky unpacks the human brain as an evolutionary nesting doll, where the deepest structures are the oldest, simplest, and most vital — from the net-like reticular formation inherited from creatures resembling hydras, to the pineal gland that was once a fourth eye on top of a fish's head. He traces how the cerebellum, basal ganglia, and cortex each accumulated archaic, paleo-, and neo- layers, why humans have almost no true instincts beyond a reflexive eyebrow flash, and how the limbic system still judges people by smell at roughly the level of a lancelet. Along the way he explains why our inherited feeding rules — eat everything, prefer sweets, store fat — sabotage us in a world of full refrigerators and 24-hour shops, and how Delgado's electrode experiments showed that aggression in cats, bulls, macaques, and humans can be switched on and off through nearly identical brain structures. The talk closes on fear, dominance hierarchies shared across all mammals, humanity's unique talent for rotating leadership, and the strikingly stable group size of about thirty that has persisted since the australopithecines.

Why Your Food Should Energize You, Not Put You to Sleep: A Physician's Guide to Active Longevity

Physician and biophysicist Yakov Marshak explains how the Neolithic shift from oil-rich wild seeds to cooked grains rewired the human food instinct — replacing slow hunger with urgent appetite and turning meals from stimulating into sedating. He outlines a simple pulse test for detecting individual food intolerance, the three pillars of "stimulant nutrition" (digestible protein, fiber, and spices), and the leaky-gut cascade that links poor digestion to chronic inflammation. The conversation also covers the biochemistry of arterial plaque and a pomegranate-and-cocoa combination that reportedly reversed atherosclerosis, plus a candid look at A1 versus A2 milk, homogenization, and gout. The core message: healthy eating is deeply individual, and a proper meal should leave you energized rather than reaching for the sofa.

Generation Ship: How the Microbes in Your Gut Shape Who You Are

The human gut hosts the densest microbial community on Earth — hundreds of bacterial, archaeal, and fungal species carrying roughly 100 times more genes than our own genome — and they do far more than digest food. This post explores how the microbiome defends us from pathogens, trains the immune system, and communicates with the brain through the gut–brain axis, influencing sleep, mood, and even personality traits. Analysis of 2,000-year-old preserved stool reveals that industrialized diets have wiped out entire bacterial species, leaving modern guts less diverse, less adaptable, and more prone to conditions like Crohn's disease, diabetes, and obesity. With fecal transplants already reversing cognitive decline in aging mice, manipulating our microbial partners may soon become a genuine medical tool — though far more questions remain open than answered.
