perhaps he can write something about the famous paul octopus, who has predicted world cup scores with high accuracy. it's a good popular science topic, considering chinese fever for world cup and superstition tradition.

yesterday i saw cctvnews gave some scientific explanation (guess adapted from foreign news):

octopus likes bright colors such as red and yellow, no wonder germany and spain usually got picked, and he picked germany beat uruguay, spain beat holland, we shall know in two days.

holland and uruguya flags are much less "attractive", but germany and spain ones should be close, as paul chose germany before 2008 eurocup final (which he got wrong), but this time picked spain (right)
