As many self-healing polymers as we've seen roll across our screens, we never really tire of them -- chalk it up to our unending quest for perfection, but we like our gadgets devoid of nicks and scratches. Lucky for us, a team of scientists that shares our need for clean has produced a material that fixes its imperfections in a mere 60 seconds when exposed to UV light. The typically rigid material basically melts down when exposed to rays of a specific wavelength, allowing it to fill in any nicks or dings. When the light is lifted, the polymer goes back to its original form, and voila -- the surface is like new. Its creators say
