Why does sweat smell? Contrary to popular belief, sweat doesnБt smell. ItБs a clear, odourless liquid mostly made up of water, salt, proteins and oils.

The molecules are packed closer together. The amount of water vapor in the air also affects the density of the air. The more water vapor that is in the air, the less dense the air becomes. ...

To celebrate, we asked an actual newcomer in the office if she knew why citrus trunks are painted white, and she said it was to repel insects. These comical newcomers. We were going to laugh at her until we remembered she is much higher up the food chain than us and holds what passes for our career in her elegant and well-manicured hands. So we didnБt laugh. Just to double-check, and to look busy, we called Ralph Backhaus, a professor of plant
