Rare blue proteins from cold-adapted microbes could serve as prototypes for molecular on-off switches

Imagine the magnificent glaciers of Greenland, the eternal snow of the Tibetan high mountains, and the permanently ice-cold groundwater in Finland. As cold and beautiful as these are, for the structural biologist Kirill Kovalev, they are more importantly home to unusual molecules that could control brain cells' activity.
