This skin is complex and unusual; it is thinner than typical mammalian skin and contains organized bundles of elastin and embedded skeletal muscles. These elements are likely responsible for controlling the shape of the wing during flight and contributing to the aerodynamic capabilities of bats.

The twitch duration of mesothoracic, first tergocoxal (Tcxl) wing muscles is only about one-half the duration of the upstroke or downstroke portion of the wing cycle. During tethered flight the Tcxl muscles are activated on each cycle with short bursts of action potentials, each burst typically containing four action potentials. Activating th

AbstractAquatic birds show a great diversity of locomotion styles and wing morphologies, from penguins that are fully specialized for an aquatic life to species of aerial flyers that also use their wings for underwater propulsion (e.g. auks and shearwaters). Moving between the air–water interface exerts conflicting pressures on the body and wing anatomy of diving birds. In this work, we investigated the functional morphology of the forelimb musculature of 18 species of aquatic birds that display a variety of flight and foraging styles.

Recent studies on bird flight propose that hotter wing surfaces reduce skin friction drag, thereby improving flight efficiency (lift-to-drag ratio). Darker wings may in turn heat up faster under solar radiation than lighter wings. We used three methods to test the impact of colour on wing surface temperature. First, we modelled surface temperature based on reflectance measurements. Second, we used thermal imaging on live ospreys ( Pandion haliaetus ) to examine surface temperature changes with increasing solar irradiance. Third, we experimentally heated differently coloured wings in a wind tun

Abstract:
Male courtship songs in Drosophila are exceedingly diverse across species. While much of this variation is understood to have evolved from changes in the central nervous system, evolutionary transitions in the wing muscles that control the song may have also contributed to song diversity. Here, focusing on a group of four wing muscles that are known to influence courtship song in Drosophila melanogaster, we investigate the evolutionary history of wing muscle anatomy of males and females from 19 Drosophila species. We find that three of the wing muscles have evolved sexual dimorphisms in size m

Abstract:
Take-off is how a bird initiates flight and is important for predator evasion and therefore survival. A birds’ take-off ability is affected by the mechanical power available from the flight muscles, the size and shape of the wings, the mechanical control of the wings and therefore the wing beat kinematics, and the body weight that needs to be supported. How a birds’ body weight, size, shape and dynamic motions of their wings interact with the air flow during flight, will determine flight performance and trade-offs in wing morphology are likely due to different morphologies being optimal for di

‘On the move’ considers the insect wing as a remarkable structure. Aside from vertebrates, insects are the only animals that use flapping wings for locomotion. Insects are unique among the invertebrates as they developed the ability to fly, although this characteristic has been lost in many species and some orders. Unlike those of other animals, insect wing muscles can contract multiple times for each single nerve impulse, allowing the wings to beat faster than would otherwise be possible. It is worth taking a look at dragonflies, which have additional small accessory flight muscles that contr

Abstract The locomotory centre of winged insects is the thorax. The two wing-bearing segments (the meso- and metathorax) form the ‘pterothorax’. It is in the thoracic muscles of the wing that energy is transformed from chemical into mechanical form. Hence, the pterothorax can be compared with the engine of an aeroplane (Fig. 1.1). Power generated by contraction of the muscles is transmitted to the propulsive device-the wings-through the skeleton and the system of the axillary sclerites in the wing bases. The insect flaps its wings and thus generates aerodynamic forces. The insect uses differen

It was known before that the halteres, which beat antiphase to the wings, act as gyroscopes which stabilize flight on all three axes by feeding information directly to the wing muscles.

Abstract:
Abstract This study introduces the aerodynamic forces measurements of a novel bio-inspired drone design, drawing inspiration from bat flight dynamics while using Shape Memory Alloy (SMA) micro-wires as artificial muscles. Unlike conventional drones powered by motors coupled with gears, this bio-mimetic drone relies on an agonist-antagonist muscle-like system of SMA wires activated by an electrical signal, imitating the animal wing structure. The presented research focuses on lift measurements derived from a flapping wing operating at different frequencies. The combination of SMA micro-wire ago

Abstract:
Several grape varieties and red wines were found to contain large concentration of phenolic compounds which work as antioxidant in-vitro and in-vivo. Wastes from wine production contain antioxidants in large amounts, between 2-6% on dry material basis. Red wines but also white wines were found to prevent lipid peroxidation of turkey muscle tissues stored at 5oC. The antioxidant reaction of flavonoids found in red wines against lipid peroxidation were found to depend on the structure of the molecule. Red wine flavonoids containing an orthodihydroxy structure around the B ring were found highly

Abstract:
“Environmental justice is not just about the environment-it about people. It’s about dignity. It’s about equity.” The damage we do to the planet does not land evenly. Dark smoke hangs over busy, low-income neighbourhoods, while coastlines that poor island families call home slowly slip below wave after wave. Too often, those who did the least to cause the problem feel the blow first and hardest. That imbalance sits at the heart of environmental justice. It says that caring for nature and caring for people must walk hand in hand. When a new mine opens, a highway stretches through a community, o
