Long before a distant herd comes into view, an elephant likely already knows it is coming, thanks to silent messages sent through the ground.

Female Megalopta sweat bees must choose whether to remain as helpers in their mother’s nest or leave to reproduce independently.

A minimal wake-vortex model explains how a bird following behind and to the side of another can reduce the mechanical power needed for flight by about 11 percent.

Kagoshima University researchers identified methyl benzoate as an airborne plant-defence signal whose release rises around dusk. Plants receiving the compound activate defence-related genes through NPR1, a central regulator of plant immunity, using a response pattern distinct from the better-known signal methyl salicylate.

Researchers selectively silenced neural circuits associated with the doublesex gene in older honeybee workers and caused them to resume queen-care duties normally performed by younger bees.

A new agent-based model suggests that Andean condors can reduce the energetic cost of long-distance flight by using the movements of other birds as continuously updated social information.

To Which Quorum Should a Bacterium Listen? In the first article on microbial communication, we saw how bacteria release chemical signals that accumulate as a population grows.

Researchers found that aphids transfer several of their own microRNAs, together with the regulatory protein Argonaute 1, into Buchnera bacteria living inside specialised host cells.

Greater Japanese horseshoe bats gradually converge on a shared echolocation frequency after unfamiliar individuals join a colony. Instead of separating their signals into individual channels, lower-frequency bats shift upward until colony members preserve a common clutter-free band in which echoes from fluttering prey remain detectable.

Wood ants maintaining their nests can move sticks cooperatively even when there is no shared destination or leader directing the task.
