Researchers Develop Self-Healing Plastic 71
schliz writes "Arizona State researchers have been working on a 'self-healing' polymer that uses a fibre optic 'nervous system' to detect and fix cracks. The system recovers up to 96 percent of an object's original strength in laboratory tests. It could find use in 'large-scale composite structures for which human intervention would be difficult,' such as wind turbines, satellites, aircraft, or the Mars Rover."

Frogs are very advanced. One could argue that they're more "advanced" than humans (in terms of anatomical specialisation).

Also, a fair bit of the issue is cost per mile.
We could build, right now, with modern technology, roads that could go decades or longer between repaving or other maintenance. No self-healing wonderplastic required; modern engineering and existing materials are up to the task. Wouldn't last forever, but if you only need to make repairs every eighty odd years, that's more than good enough. It might even been economical in the very, very long run.
The reason we don't do this is money. Simple asphalt and gravel, with sporadic repairs and repaving every decade or so is "good enough". Long term savings that would take most of a human lifespan to pay off aren't attractive to anybody in a position to implement them, for obvious reasons.

Every Terminator movie is "the \"I'll be back\" one", it's one of the movies catchphrases. Actually I think 2 is the one that uses it most.
While the first one is the most shocking and new one, 2 is absolutely the best of the franchise. I consider it Cameron's best movie.

Half the reason these things end up in the junk yard to begin with is they get into some kind of accident which generally screws up the bumpers. And due to exposure differences you get different paint fade characteristics which cause color matches to look like color mismatches.

One of my father's favorite stories is about a time he brought his car to a body shop to get a dent fixed. It was a dent in the trunk, roughly the size of a basketball. The guy wanted $450 to fix it (this was many years ago, so inflate to whatever sounds appropriate). He declined. When he got back home and took another look at it, he got pissed off about the whole thing and slammed his fist into the trunk... which caused most of the dent to pop back into place. What was left was closer to the size of a tennis ball. He went back to the same guy a week later and they quoted him $50 for it. He's always referred to it as his $400 punch.

It just grows stronger and returns to its original shape when cracked. A clean break would not be able to be healed. And that "repair" will fail if they ever turn off the lights in the fiber optics because the crack is still there and the strengthened plastic near the crack will cool back down.
