Effective biodegradation of chicken feather waste by co-cultivation of keratinase producing strains
BackgroundChicken feather, a byproduct of poultry-processing industries, are considered a potential high-quality protein supplement owing to their crude protein content of more than 85%. Nonetheless, chicken feathers have been classified as waste because

Feathers account for 5–7% of the total weight of chicken have become one of the major pollutants due to their recalcitrant nature. Feather which is constituted of 90% keratin can be a good source of peptides, amino acids, and minerals for use as organic ...

The Making of a Flight Feather: Bio-architectural Principles and Adaptation.
The evolution of flight in feathered dinosaurs and early birds over millions of years required flight feathers whose architecture features hierarchical branches. While barb-based feather forms were investigated, feather shafts and vanes are understudied.

Adaptation of feathered dinosaurs and Mesozoic birds to new ecological niches was potentiated by rapid diversification of feather vane shapes. The molecular mechanism driving this spectacular process remains unclear.

Feather corticosterone levels on wintering grounds have no carry-over effects on breeding among three populations of great skuas (Stercorarius skua) [PDF]
Environmental conditions encountered by migratory seabirds in their wintering areas can shape their fitness. However, the underlying physiological mechanisms remain largely unknown as birds are relatively inaccessible during winter.

Exposing image forgery by detecting traces of feather operation [PDF]
Powerful digital image editing tools make it very easy to produce a perfect image forgery. The feather operation is necessary when tampering an image by copy–paste operation because it can help the boundary of pasted object to blend smoothly and ...

Early feather pecking as a form of social exploration:the effect of group stability on feather pecking and tonic immobility in domestic chicks [PDF]
In two lines of White Leghorns that differ in their propensity to feather peck, feather pecking was already present I day after hatching. A significant line difference developed within 3 days and this difference remained in the following weeks. There was
