Scientists have investigated whether zebrafish use social learning to assess risk. They found that wild zebrafish, which are more timid than their domesticated counterparts, became emboldened after interacting with domesticated zebrafish. The opposite did not occur, however.

A key component found in an ancient anaerobic microorganism may serve as a sensor to detect potentially fatal oxygen, researchers have found. This helps researchers learn more about the function of these components, called iron-sulfur clusters, which occur in different parts of cells in all living creatures.
