A 2-year field study has demonstrated that volatile compounds produced by plants when they are attacked by herbivores act as defenses by attracting predators to the herbivores and increasing the reproduction of the plants.

The ability of Manduca moths to recognize changes in the profile of volatile compounds released by plants being attacked by Manduca caterpillars allows them to lay their eggs on plants that are less likely to be attacked by insects and other predators, and to avoid competing against other caterpillars of the same species for resources.

A transport protein enables leaf beetle larvae to take up and store plant toxins and use them as part of their own defense strategy.

The transcriptional regulator BZR1 acts as a molecular integrator of environmental cues regulating the trade-off between growth and innate immunity.

Rats show socially selective helping behavior based on familiarity with the type of rat, but not necessarily the individual rat.

Triacylglycerides found in the males of 11 species of Drosophila form a largely overlooked, novel, sex-specific class of pheromones that act to suppress courtship behaviour.

Male and female mice respond differently to the same pheromone signals, and the representation of these sensory stimuli by neurons in the medial amygdala correlates precisely with the differences in behavior.

Primate amygdala neurons provide a coordinated representation of space and motivational significance whereby amygdala responses to visual stimuli predicting either rewards or aversive stimuli could influence spatial attention in a similar manner.
