cc: "Nostoc are a genus of cyanobacteria known for gathering their thin, thread-like bodies into gelatinous colonies, forming what look like, basically, a weird noodle soup. Of course you might not want your bowl of noodle soup to be bright green like this, and that is fair. But outside the world of imagined meals, the color of cyanobacteria like nostoc are an indicator of their life-sustaining ability, turning their chlorophyll into a vivid display as they reflect green wavelengths into our vision. Then, with a flick of a switch, we can change the light on our sample from white light to ultraviolet light and everything changes. Our soup of filaments is now a bright, bright red, like we just doused our noodles in hot sauce."
