COVER: A hydrothermal vent boils at 325 °C in the Niua South volcano, in the Tonga volcanic arc, South Pacific Ocean. In addition to the metal sulfides typically comprising the “black smoke,” this system also contains gold colloids that form upon boiling. See “Boiling-induced formation of colloidal gold in black smoker hydrothermal fluids” by Gartman et al., p. 39–42 in the January 2018 issue of Geology.
