Researchers have known for decades that concrete fixes itself as cement particles near a small crack mix with air and water to form calcium carbonate. But some fractures are too big to heal on their own. Now engineers at the University of Michigan have mixed a new concrete formula with reinforcing glue-like fibers that hold it together under pressure, allowing only hair-width cracks that can mend after a rainy day. Available in a few years, the remixed concrete will cost more than the standard stuff, but less maintenance could make it cheaper in the long run.
i need some self healing sunglasses. well i always got krazy glue.
The first 2 are fascinating, but I don't know what chip types are being discussed for the transistor bypass.
An Intel Core 2 Duo processor has 291,000,000 transistors, so that's probably not the target. This is an extreme, but there are many chips in the 100k transistor range. Maybe there are some details, not mentioned here, that would make this concept seem more reasonable.
Having the healing chips would be excellent for aircraft. Having it on a desktop chip would be amazing because there are so many transistors i doubt you would notice one out.
