The striking appearance of the Eurasian Jay owes much to its beautiful striped feathers.  What’s interesting about these is that the colours of the feathers are not produced by a pigment – instead they are a result of an optical interference effect arising from the sub-micron structure created in the cells that form the feather. We’ve studied this structure – and analogous structures from beetle scales – using synchrotron x-ray radiation, and we find that these structures are characteristic of a process of controlled…
