A metal that has never been recorded before turned up in a grain of sand from Hiroshima Bay. The bead is a hiroshimaite, one of the melted spherules recovered from the beach sands around the bay. The metal grain inside it measures a few micrometers across and sits in a matrix of glass that cooled too fast to crystallize. "This finding demonstrates that nuclear plasma events may stabilize complex metallic phases and highlights atomic-blast debris as a natural laboratory for nonequilibrium alloy formation and materials discovery," the paper concludes.
