LIGHT COULD HEAL MATERIALS
New material repairs itself when exposed to ultraviolet light

Scientist found out that ultraviolet light can heal scratches on cars or any other scratches. When the scratches is expose to sunshine for a long period, the scratches will heal, meaning, the scratched part will be gone. But it will take a longer time to heal, whereas, if you want it to recover fast, just shine ultraviolet light over it, it will heal faster. Scientists have used a substance from the shells of shrimp to create a new material that repairs itself when exposed to ultraviolet light. Scientist are still investigating other things that can be heal like all kinds of coatings, such as paints, and surfaces on everything from surgical instruments to countertops. Materials is acting just like out body. When we fall and hurt ourselves, our cells and with the help of medical oil, our wound will heal. For materials, when they get scratched, it will "bleed", but it will remake bonds through an interaction with an external stimulus such as heat, water or, in this case, UV light.
