Nature's strongest material yet

Nature's strongest material yet

Scientists at the University of Portsmouth have discovered that the teeth of limpets (shelled aquatic snails) are the strongest biological material on earth. Previously spider silk was believed to be the strongest natural material, however, the strength calculated for this tooth material was five gigapascals - some five times that of spider silk.

To put this in perspective against man-made materials, limpet teeth are stronger than Kevlar and even rivals some high-tensile carbon fibre products.

Imagine the possibilities for the next generation of airplanes, tooth implants or high-performance bicycles!
