What does it mean to be thirsty?

Because these brain areas are difficult to study — due not only to their location, but also to their composition, with many different cell types and crisscrossed circuitry — it’s only in the last decade or so that neuroscientists have begun to understand how thirst fundamentally works.

How those sensors work, or what they even are, continues to elude sc

Fish was an important part of the ancient Roman diet, and Romans processed their catch for long-term preservation in coastal fish-salting plants called cetariae. There, they crushed and fermented small fish into pastes and sauces such as the iconic umami-flavored
