End of the smashed phone screen? Self-healing glass discovered by accident

New type of polymer glass that can mend itself when pressed together is in development by University of Tokyo after a student discovered it

Japanese researchers say they have developed a new type of glass that can heal itself from cracks and breaks.

Glass made from a low weight polymer called "polyether-thioureas" can heal breaks when pressed together by hand without the need for high heat to melt the material.
