Did you know that secretly… we are all electricians? Every single cell in your body—from your skin to your brain—runs on electricity. You are literally powered by ion flows, voltage gradients, and tiny biological batteries humming inside your tissues right now.

We're exploring developmental bioelectricity—the study of how cells use electrical signals to shape bodies, heal wounds, and even regenerate missing organs. Most people think electricity in the body only happens in the brain or the heart. But modern research has shown that every cell has a voltage, called the resting membrane potential.

Episode Timeline & Key Points:

[0:00] Introduction - You're All Electricians

  • Hook: Every cell runs on electricity
  • Lia's "Botox to Bolts" connection to anatomy

[1:30] Bioelectricity Fundamentals

  • Resting membrane potential explained
  • Research from pioneers like Michael Levin

[4:15] Cellular Power Generation

  • Ion movements (sodium, potassium, chloride, calcium)
  • Cell membranes as electrical barriers

[7:20] Voltage as Communication

  • Cells use voltage patterns, not just chemicals
  • Examples: liver cells, skin cells, embryonic cells

[10:45] Developmental Bioelectricity

  • Embryonic voltage mapping
  • Michael Levin's "instructional code" concept

[14:30] Slow vs. Fast Electrical Signals

  • Analog "dimmer" vs. digital "switch" analogy

[18:15] Body's Electrical Architecture

  • Gene expression regulation
  • Cell proliferation control
  • Organ placement coordination

[22:00] Electrochemical Balance

  • Chemical and electrical gradients interconnected

  • Electrotaxis: cells following electrical signals

[29:45] Regeneration Research

  • Animal model discoveries
  • Xenopus frogs, planaria, zebrafish examples

[33:20] V-ATPase Breakthrough

  • Adams & Levin (2007) research
  • Electrical signals controlling regeneration

[36:00] Closing & Implications

  • Body as walking electrical grid
  • Connection to skilled trades perspective
