Trinity College DublinHow Insects Repair Their ‘Bones’ - Biomechanics researchers from Trinity College Dublin have discovered how insects build internal bandages to repair their broken ‘bones’.

A DIY cuticle repair kit allows wounded insects to go about their day-to-day lives almost as efficiently as they would have done before meeting with mishap.When an insect cuts one of its legs, it kicks into repair mode by laying a patch of new cuticle underneath the affected area. This new cuticle effectively functions as a bandage, which seals the wound and provides structural strength where it is required.

The study, which has just been published in international journal Interface, is the first to ever assess the biomechanics of repair in arthropods. Insects are the most species-diverse group of animals on the planet
