The Oxygen–Antioxidant Paradox
Advanced life requires the efficient processing of energy to perform work. Only the oxidation of carbohydrates, starches, and fats can deliver the necessary efficiency. However, the presence of oxygen … more
Explanation for Origin-of-Life’s Molecular Handedness is Insoluble
One of my teenage daughters is left-handed. And nobody in our family wants to sit next to her when we eat at the table. It’s not because she has bad manners. It’s because her left arm … more
