A certain sequence of letters, EBU, creates chemical conditions in which an iron atom disconnects itself from an organic molecule (on the right), activating it and causing it to emit green fluorescent light. The sequence EUB leads to the emission of blue light. Other sequences of letters do not cause light emission

A portion of the mouse hypothalamus reveals that the protein made by the Otp gene (green) is expressed in all the neurons (red) that drive hunger – and the combined color is therefore yellow. It was known that in the developing brain, Otp is needed for the generation of these neurons. The study found that during adulthood, Otp is crucial for causing these neurons to express AgRP, a major hunger-promoting substance
