Behaviors linked to adult crime differ between abused boys and girls, study finds

A new study from the University of Washington suggests that abusive children can exhibit either 'externalizing' (arguing, disobedience, fighting) or 'internalizing' (depression, withdrawal) behaviors, which are predictors of later criminal activity. Abused girls who internalize their emotions are more likely to commit crimes as adults.

Predators might not be dazzled by stripes

Research suggests that stripes do not provide an advantage for animals living in groups when multiple targets are presented simultaneously. This contradicts the long-held assumption that stripes evolved to make it difficult for predators to capture animals moving in a group.
