Résumé

The Youtube channel Zeste de science explores all aspects of scientific research, proving that even the most complicated scientific facts can be explained in less than 5 minutes, and that even the most seemingly trivial events of everyday life, if thoroughly studied, can contribute to the biggest technological advances.
Episode 30: A research team developed an experiment to study emotions in a particular species of fish, the convict cichlids. The females are trained to receive two boxes in their aquarium, one with a white lid, the second with a black lid. Little by little, the fish understand that only the box with a white lid contains a reward. It is therefore opened systematically. Creating an ambivalent situation with a box with a grey lid makes it possible to measure the animal's degree of optimism based on its reactions. These small tropical fish are known to be monogamous. Therefore, a decrease in optimism is observed in the female when forced apart from its breeding male.

Our work is guided by the way scientists question the world around them and we translate their research into images to help people to understand the world better and to awaken their curiosity and wonderment.
