Phenylethylamine: from Cacao to the Brain, the Chemistry of Mood
Cacao contains phenylethylamine — the same amine the brain releases during falling in love and intense exercise. A small molecule with simple chemistry and a neurological effect that has fascinated humanity for centuries.
Water: the Most Studied and Most Underestimated Molecule in Chemistry
Water appears simple — H₂O, two hydrogens and one oxygen. But its physical and chemical properties are so anomalous that if water behaved as elementary chemistry predicts, life on Earth would be impossible.
Cholesterol: the Most Misunderstood Molecule in Nutrition
Cholesterol is not poison — it is an essential molecule that cells cannot live without. The problem is not cholesterol itself, but where it is, how much there is, and what type of particle it travels in.
