Self-healing materials
Scientists discover construction materials that can undo the damage caused by radiation
Xian-Ming Bai and colleagues at the Los Alamos National Laboratory (LANL), US, showed, using computer simulations on nano-crystalline copper materials, that when these materials are exposed to radiation and damage occurs they can 'heal' themselves by reversing the migration of atoms within the material's structure when it is further bombarded with radiation.
