What makes a feather shine? A nanostructural basis for glossy black colours in feathers.
Colours in feathers are produced by pigments or by nanostructurally organized tissues that interact with light. One of the simplest nanostructures is a single layer of keratin overlying a linearly organized layer of melanosomes that create iridescent colours of feather barbules through thin-film interference. Recently, it has been hypothesized that glossy (i.e. high specular reflectance) black ...
متن کاملPhysical methods for investigating structural colours in biological systems.
Many biological systems are known to use structural colour effects to generate aspects of their appearance and visibility. The study of these phenomena has informed an eclectic group of fields ranging, for example, from evolutionary processes in behavioural biology to micro-optical devices in technologically engineered systems. However, biological photonic systems are invariably structurally an...
متن کاملThe diversity and implications of animal structural colours.
Diffraction gratings were believed to be a rare cause of colour in nature. However, surface gratings, which include diffraction gratings and Bragg gratings, appear to occur in many forms within a diversity of animals. Structural colours in general have implications in the study of animal behaviour and evolution.
متن کاملKey to xenobiotic carotenoids.
A listing of carotenoids with heteroatoms (X = F, Cl, Br, I, Si, N, S, Se, Fe) directly attached to the carotenoid carbon skeleton has been compiled. The 178 listed carotenoids with C, H, X atoms demonstrate that the classical division of carotenoids into hydrocarbon carotenoids (C, H) and xanthophylls (C, H, O) has become obsolete.
متن کاملTaking a shine to it: How the preference for glossy stems from an innate need for water
Human beings are attracted to glossy objects. However, the investigation of whether this preference for glossy is a systematic bias, and the rationale for why, has received little or no attention. Drawing on an evolutionary psychology framework, we propose and test the hypothesis that the preference for glossy stems from an innate preference for fresh water as a valuable resource. In a set of s...
