Visual Neuroscience: How Do Moths See to Fly at Night?
A new study shows that moth vision trades speed and resolution for contrast sensitivity at night. These remarkable neural adaptations take place in the higher-order neurons of the hawkmoth motion vision pathway and allow the insects to see during night flights.
متن کاملFly - By - Night Firms , Credit , and Regulation : A Simple Model Philip
“Fly-by-night” is a derisive term for a firm that appears to be untrustworthy and/or transient. Previous studies have focused on general fly-by-night firms’ behavior and their interaction with the credit market, while much less has been done to show how they approach government regulation.

While these diseases remain important diagnostic considerations in patients with night sweats, other diagnosi...
متن کاملHow to trick mother nature into letting you fly around or stay up all night.
Night shift work and rapid transmeridian travel result in a misalignment between circadian rhythms and the new times for sleep, wake, and work, which has health and safety implications for both the individual involved and the general public. Entrainment to the new sleep/wake schedule requires circadian rhythms to be phase-shifted, but this is often slow or impeded. The authors show superimposed...
متن کاملHornets Can Fly at Night without Obvious Adaptations of Eyes and Ocelli
Hornets, the largest social wasps, have a reputation of being facultatively nocturnal. Here we confirm flight activity of hornet workers in dim twilight. We studied the eyes and ocelli of European hornets (Vespa crabro) and common wasps (Vespula vulgaris) with the goal to find the optical and anatomical adaptations that enable them to fly in dim light. Adaptations described for obligately noctu...
