A bacterium sees red : Chlorophyll f (Chl f), a tetrapyrrole displaying unprecedented red‐shifted absorption bands, was discovered in cyanobacteria and its structure was deduced by spectroscopic means. The new chromophore of Chl f is likely a result of biological adaptation and biochemical optimization in bacteria in their struggle for survival. It is a sign of life's constant demand for energy obtained from sunlight through photosynthesis.
