Not flying blind: a comparative study of photoreceptor function in flying and non-flying cockroaches.
Flying is often associated with superior visual performance, as good vision is crucial for detection and implementation of rapid visually guided aerial movements. To understand the evolution of insect visual systems it is therefore important to compare phylogenetically related species with different investments in flight capability. Here, we describe and compare morphological and electrophysiol...
متن کاملHoneybee: The flying pharmacist
Honeybee, a small -although powerful- creature moves from one place to another to make an elixir, which cures different diseases. To make one kilogram of honey the small creature has to carry 150000 pieces of pollen and suck the sap of ten million flowers. Both honey and the honeybee poison have been used in treating diseases for thousands of years. The product made by such tiny creatures has b...

متن کاملFlying Blind: The Case for a Spatial Framework for Semantic Information
Urban environments require cognitive abilities focused on both spatial overview and detailed understanding of uses and places. These abilities are distinct but overlap and reinforce each other. Experimental recall of spatial and semantic information indicates that using a road map enables subjects to demonstrate a significantly better spatial understanding, identify semantic elements more often...
متن کاملFlying by Ear: Blind Flight with a Music-Based Artificial Horizon
Two experiments were conducted in actual flight operations to evaluate an audio artificial horizon display that imposed aircraft attitude information on pilot-selected music. The first experiment examined a pilot’s ability to identify, with vision obscured, a change in aircraft roll or pitch, with and without the audio artificial horizon display. The results suggest that the audio horizon displ...
