Harder than Diamond: Superior Indentation Strength of Wurtzite BN and Lonsdaleite Recent indentation experiments indicate that Wurtzite BN (w-BN) exhibits surprisingly high hardness that rivals that of diamond. Here we unveil a novel two-stage shear deformation mechanism responsible for t...

KOI 500, is one of the most interesting because the planets so closely orbit the parent star. There are five of them, with periods that range from just under a single day to 9.5 days. It resembles Jupiter's system of moons in that regard. Jupiter's three largest inner moons orbit the planet orbit in 1:2...
