Further proof of extraterrestrial origin of quasicrystals

Further proof of extraterrestrial origin of quasicrystals - physicsworld.com: "An international team of researchers has found nine new samples of naturally occurring quasicrystals. The work also provides further proof that quasicrystals were delivered to the Earth by a meteorite. The team's discovery challenges our understanding of both crystallography and solar-system formation."
