SCIENCE NEWS: Researchers at the University of Bonn say they’ve taught a popular aquarium fish—cichlids—to do math. The scientists used the color blue as a prompt to add one, and the color yellow as a prompt to subtract one. (earthsky.org)

Delighted by their acrobatics
As they swim up and down, with their eyes cold and blank,
Are they working on their mathematics?
