Scientists have devised a coating that, when scratched, heals itself upon exposure to sunlight. Polymeric self-healing composites are used for longer lasting products. Sewers have long had a cutting board which has possessed that self-healing power.
Mankind as some self-healing powers in physical makeup and is working on making more of that possible. For the last eight years Bush stopped research with the type of stem cells which had the most promise for success. If I understand their potential greatest usage is that they will be used as closely to self-healing in the human body as any product we have today. Embryonic stem cells show the most promise because they have the most potential for being easily persuaded to become the type of cells needed to be corrective for innumerable conditions and illnesses.
