Dwarf planet diamonds could hold the key to stronger machine parts

Strange diamonds from an ancient dwarf planet in our solar system could lead to the production of ultra-hard machine parts, according to scientists. A team of researchers, including those from Australia’s national science agency, CSIRO, has confirmed the existence of lonsdaleite in ureilite meteorites from the dwarf planet’s mantle.

  Lonsdaleite is a rare, hexagonal-shaped diamond believed to be much stronger and harder than the more typical cubic version. Research led by Monash University, in collaboration with CSIRO, RMIT...
