Overview: The #CoffeeRingEffect causes stains to be darker at the edges. This happens because water evaporates faster at the droplet's edge, which gets 'pinned' on rough surfaces, transporting coffee particles to the perimeter. #Science 1/5

Evaporation controls contact-dependent bacterial killing during surface-associated growth Abstract. Many bacteria employ contact-dependent killing mechanisms, which require direct physical contact with a target cell, to gain an advantage over co
