This study reanalyzes navigation data and conducts a virtual reality experiment to reveal persistent individual left/right biases in path integration, which are obscured by population-level averaging.

This study shows bumblebees can associate visual cues with collision experiences, avoiding high-risk areas based on cues before or after collisions.

This study shows that experienced bumblebees optimize flight in cluttered environments through learning, not just reflexes, as transparent obstacles affect naive bees more than experienced ones.

This study investigates how bumblebees estimate height in 3D space using ventral optic flow and local/global cues during foraging.

This study shows bumblebees adjust their flight altitude and orientation in dense environments to navigate and locate their nest more effectively.

This study investigates how humans combine path integration and landmark cues in virtual navigation, finding that performance varies with environment complexity and individual differences in cue usage.

This study shows bumblebees primarily use ground-level views, not birds-eye views, to navigate dense environments, challenging existing snapshot-homing models.
