In the epic battle of soap bubble versus drop of water, the surprising winner is the bubble. This is because of the bubble's ability to "self-heal" as the drop first splashes down through it, and then back up through it again. We'll give you some of the physics behind why the bubble can heal itself.
This plastic heals itself through a process that's eerily reminiscent of blood clotting. It contains a network of capillaries that deliver healing chemicals to damaged areas. So in the future, the cracked screen of your phone could mend itself.
An odd quirk of iron led, eventually, to the first self-healing materials. An iron bar, dipped in strong acid, was just fine. Dipped in weak acid, it was eaten away to nothing. Here's why a diluted acid will succeed when a strong acid fails.
In the wake of yesterday's 4.4 earthquake in the Los Angeles area, some seismologists are suggesting that this could be the first of many quakes in the region. As the city looks to a shaky future, there are two cutting-edge technologies that might keep their buildings, bridges and transit systems from crumbling.
The Spanish scientists who developed it are calling it the 'Terminator' Polymer — and for good reason. Like the T-1000 blown to bits, it can spontaneously and independently repair itself without any outside intervention.
Earlier this week, scientists announced the development of an entirely new genre of plastic that heals itself when it's scratched or cut, and bleeds like human skin — but researchers say you're more likely to find these next-gen materials wrapped around a car bumper than you are a freshly minted 800 Series.
Scientists have discovered a new polymer that could be repaired with nothing more than UV light. The material is a metallosupramolecular polymer, a rubbery substance with bits of metal throughout. It's made of molecular chains which naturally latch together to form bigger ones, in a stable lattice. When damaged, this…
