Controlling airborne cues to study small animal navigation

Animal Navigation: A Galaxy of Cues

Elegant new experiments show that on clear nights and in the absence of other celestial cues, dung beetles can orient their routes to the band of stars known as the Milky Way.

Animal navigation

Nearly all animals move in an oriented way, but navigation is something more: the directed movement toward a goal, as opposed to steering toward or away from, say, light or gravity. Navigation involves the neural processing of sensory inputs to determine a direction and perhaps distance. For instance, if a honey bee were to seek food south of its hive, it would depart from home with the sun to ...

Autonomous Airborne Video-Aided Navigation

We present an autonomous airborne video-aided navigation system that uses video from an onboard camera, data from an IMU, and digitally stored georeferenced landmark images. The system enables self-contained navigation in the absence of GPS. Relative position and motion are tracked by comparing simple mathematical representations of consecutive video frames. Periodically, a single image frame i...

Controlling exposure to laboratory animal allergens.

Laboratory animal allergy (LAA) is a significant occupational disease that may affect up to one third of personnel exposed to laboratory animals. Research has characterized the relative risks of exposure, in terms of intensity, frequency, and duration, associated with given tasks and work areas in the animal facility. Studies have shown that reduced exposure to animal allergens can reduce the i...
