So you'd like to know what'll cut diamonds should you need to do so, yes? This week Professor Asa Barber of the University of Portsmouth's School of Engineering spoke up on the project. Also leading the project, Barber suggested, "Until now we thought that spider silk was the strongest biological material because of its super-strength and potential applications in everything from bullet-proof vests to computer electronics." Until now, of course. Their new findings suggest that the teeth of the snail-like Limpet is stronger than any material they've found before.
The material these teeth are laced with goethite fibers. Geothite is an iron uniquely bearing diaspore hydroxide minerals (α-FeO(OH)). Before this research, it was thought that geothite only appeared in soils, in swampy areas, on cave floors, and in small bodies of water.
