Soft biohybrid morphing wings with feathers underactuated by wrist and finger motion
Science Robotics, 2020 A soft biohybrid aerial robot with underactuated feathers shows how birds can steer by morphing their wings with wrists and fingers. Since the Wright Flyer, engineers have strived to develop flying machines with morphing wings that can control flight as ...

How flight feathers stick together to form a continuous morphing wing
Science, 2020 Wing shapes take flight Birds can dynamically alter the shape of their wings during flight, although how this is accomplished is poorly understood. Matloff et al. found that two mechanisms control the movement of the individual feathers.

Feather versus non-feather bedding for asthma [PDF]
Cochrane Database of Systematic Reviews, 2000 Two recent epidemiological studies have reported that children using non-feather pillows suffered from more frequent episodes of wheeze than those using feather pillowsTo evaluate the efficacy of using feather bedding in the control of asthma symptoms.The Cochrane Airways Group asthma clinical trials register, derived from MEDLINE, EMBASE and hand ...

Valorization of Waste Feathers in the Production of New Thermal Insulation Materials
Waste and Biomass Valorization, 2020 Poultry has become the primary source of dietary protein consumed globally and as a result the by-product feathers are an increasingly problematic industrial waste. Developing a circular economy for feathers is, therefore, an important research area that

Preparation and Characterisation of Waste Poultry Feathers Composite Fibreboards
Materials, 2020 The growth of poultry meat production is increasing industrial waste quantities every year. Feathers represent a huge part of the waste, and international directives and restrictions prevent landfilling of such biodegradable materials with high burning ...

Environmental effects on magnetic fluorescent powder development of fingermarks on bird of prey feathers [PDF]
, 2019 A comparison study of the effects of environmental conditions on the development of latent fingermarks on raptor feathers using green magnetic fluorescent powder was undertaken using both sebaceous loaded and natural fingermark deposits.

Structural absorption by barbule microstructures of super black bird of paradise feathers
Nature Communications, 2018 Many studies have shown how pigments and internal nanostructures generate color in nature. External surface structures can also influence appearance, such as by causing multiple scattering of light (structural absorption) to produce a velvety, super ...
