Developmental biology: Flowers' wings, fruitflies' petals p123

The technique of clonal analysis allows dividing cells in a developing organ to be marked and tracked. The aim of such studies, in plants as well as animals, is to understand how tissues acquire their form and size.

Astronomy: Atmosphere out of that world p124

A planet orbiting very close to a Sun-like star is apparently enveloped by an extended atmosphere of hydrogen atoms, and may be losing mass because of the intense radiation from the parent star.

Behavioural science: Fair's fair p125

A basic theory of behaviour holds that people act only in their own best interests. But more complex motives are apparent in an experimental study that shows that generosity is diminished by the unfairness of others.
