    S02E01 Bonus : Sleep Paralysis | TBC - Truly BioChemical

    Step back into the dark side of REM sleep in this bonus episode of Truly BioChemical. We explore the terrifying sensory hallucinations that accompany this glitch in consciousness, from auditory rushing and phantom footsteps to olfactory decay and the crushing weight of the "incubus". What we cover this week: The Hallucination Spectrum: We break down the visual, auditory, and olfactory terrors of sleep paralysis, including the vivid sensation of air rushing through the head, the smell of decay, and out-of-body vestibular-motor hallucinations. Sleepwalking vs. Paralysis: We explain why sleepwalking safely occurs during non-REM sleep, allowing the physical body to move without the brain experiencing vivid, directed dreams. The Ion Pump Mechanism: We dive into the electrochemical mechanics of muscle paralysis, examining how the cellular potassium-sodium pump establishes a negative resting potential by pushing three sodium ions out for every two potassium ions brought in. The Neurotransmitter Cascade: We trace the biochemical signaling pathway from acetylcholine in the pons, to glutamate, to the ultimate release of GABA and glycine by the medulla. Hyperpolarizing Motor Neurons: We theorize how GABA and glycine alter cell membrane permeability—potentially by opening potassium channels to let positive charge escape—driving the internal charge lower to completely block skeletal motor neuron firing.

    S01E10 : The Haber Process | TBC - Truly BioChemical

    You are likely only alive because of this reaction. Literally. It is estimated that 50% of the nitrogen atoms in your body—in your DNA, your enzymes, your muscles—came from a factory, not nature. In the Season 1 Finale of Truly BioChemical, we tackle the most important industrial reaction in human history. We explain how two German scientists figured out how to "turn air into bread" and why this chemical breakthrough effectively detonated the human population bomb. We move from the bird-poop wars of the 19th century to the high-pressure steel reactors that sustain 8 billion people today. In this episode: The Nitrogen Problem: Nitrogen makes up 78% of the air, but the Triple Bond (N≡N) is so strong that plants can't use it. We explain the massive Activation Energy barrier required to break it.Guano Wars: A history lesson on how the world relied on limited supplies of bird droppings (Guano) before we learned to synthesize Ammonia (NH3​).The Compromise: Le Chatelier's Principle vs. Economics. Why industrial conditions (450°C, 200 atm) are a calculated trade-off between Equilibrium Yield (favored by low temp) and Reaction Rate (favored by high temp).Surface Chemistry: How the Iron Catalyst works by Adsorbing nitrogen molecules to weaken their bonds—and why Osmium would be better if it wasn't so expensive.Fritz Haber's Legacy: The dark duality of the man who saved billions from starvation with fertilizer but pioneered chemical warfare (Chlorine gas) in WWI. HIT FOLLOW and we will see you for Season 2!
