Researchers Develop Self-Healing Plastic

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."

      [Do you know what else is self healing...] ...Wolverine and the T-1000. Wolverine was alive and the T-1000 was a machine. That's it, time to take out sky net!

      And of course thirdly, what does he mean anyway? Of course one is organic and the other isn't, so what? He seems to be drawing a conclusion from these premises but neither the context nor the conclusion is stated. He might as well be saying:
