In probing mysteries of glass, researchers find a key to toughness

Innovations Report - 'Most of us think of glasses as brittle, but our finding shows that any glass can be made ductile or brittle,' said Jan Schroers, a professor of mechanical engineering and materials science at Yale, who led the research with Golden Kumar, a professor at Texas Tech University.

Ductility refers to a material's plasticity, or its ability to change shape without breaking.
