The Beast Within, the Beast Without
Drawing on and accentuating classical motifs, the surfaces of Renaissance armour are inhabited by an impressive variety of animal exuviae: leonine protomes and paws, ram’s horns, shells, tails, beaks, and wings.

Deep learning approaches to landmark detection in tsetse wing images.
Morphometric analysis of wings has been suggested for identifying and controlling isolated populations of tsetse (Glossina spp), vectors of human and animal trypanosomiasis in Africa.

Dissection of Larval and Pupal Wings of Bicyclus anynana Butterflies
The colorful wings of butterflies are emerging as model systems for evolutionary and developmental studies. Some of these studies focus on localizing gene transcripts and proteins in wings at the larval and pupal stages using techniques such as ...

Separasi Aliran pada Permukaan Atas Airfoil Kumbang Kelapa dengan Metoda China Clay
This study is aimed at identifying airfoils by mimicking the curved shape of the wings of a flying animal. This interferes with what people did in ancient times to obtain objects capable of flying.

Animalopters - towards a new dimension of flight mechanics [PDF]
Recently, it has been recognised that flapping wing propulsion can be more efficient than conventional propellers if applied to very small-scale vehicles, so-called MAVs (micro air vehicles).

Ways that Animal Wings Produce Sound
SynopsisThere are at least eight ways that wings potentially produce sound. Five mechanisms are aerodynamic sounds, created by airflow, and three are structural sound created by interactions of solid surfaces. Animal flight is low Mach (M), meaning all animals move at <30% of the speed of sound.

Structure and Chemical Organization in Damselfly Calopteryx haemorrhoidalis Wings: A Spatially Resolved FTIR and XRF Analysis with Synchrotron Radiation [PDF]
Insects represent the majority of known animal species and exploit a variety of fascinating nanotechnological concepts. We investigated the wings of the damselfly Calopteryx haemorrhoidalis, whose males have dark pigmented wings and females have slightly

Theoretical modelling of wakes from retractable flapping wings in forward flight [PDF]
A free-wake method is used to simulate the wake from retractable, jointed wings. The method serves to complement existing experimental studies that visualise flying animal wakes.

Animal migration research takes wing [PDF]
In the beginning there was great confusion about animal migration. Aristotle, noting that the types of birds around him changed with the seasons, concluded that summer redstarts turned into robins at the onset of winter, and that garden warblers became blackcaps [1]. Others thought that birds disappear in winter because they hibernate submerged in mud.
