Feather structure and bone anatomy as a biomimetic model for new adhesives and flying objects

Researchers from INM and the University of California, San Diego found that the length of the humerus bone varies in a characteristic way with the body weight of the bird to optimize lift. By contrast, the elements of the feather attachments (barbules) are spaced equally for all bird species to optimally control airflow.
