Repairable cascaded slide-lock system endows bird feathers with tear-resistance and superdurability [Biophysics and Computational Biology]

Bird feathers have aroused tremendous attention for their superdurability against tears during long flights through wind and even bushes. Although feathers may inevitably be unzipped, the separated feather vanes can be repaired easily by bill stroking. However, the mechanism underlying bird feathers' superdurability against tears remains unclear. Here, we reveal...
