Spider silk has long been hailed as the strongest known natural material, but UK scientists have discovered that the teeth of limpets—snail-like sea creatures found in the Atlantic and Pacific Oceans—may be even stronger. The research team examined limpet teeth down to the atom and found a hard mineral called goethite, the strength of which helps limpets cling to rocks and remove algae. Experts see potential in copying the structural makeup of limpet teeth for use in the manufacturing of cars, boats, and planes. More… Discuss
