☕ The Molecular Democracy: Why Coffee Affects People Differently
From section: ⏳ The liver gives caffeine a changing timetableThe pace of this process varies between people. Researchers often describe caffeine's persistence using its half-life: the time taken for its concentration to fall by about half during elimination. In adults, this commonly takes several hours, with considerable variation.

🌊 Where the Salt Stays: Why the Ocean Is Salty but Rivers and Most Lakes Are Fresh
From section: 🗺️ Salinity is a moving map of the water cycle… Where evaporation is strong and replenishment from rainfall and river inflow is limited, surface water often becomes saltier. Where precipitation is abundant, river discharge is substantial, or ice melts, surface salinity may fall. Currents and vertical mixing continually redistribute these patterns. …
