There are a lot of differences between organic and inorganic objects, but one that we're going to focus on today is that living things are self-healing and inorganic objects aren't. If you've ever cracked your phone screen, you might wish it would heal itself, but you know you have to get a new screen.

The same goes for broken toys, furniture, cars and up to airplanes. You usually have to replace what's broken. Even if you fix it, it's often left weaker and will break again.

When it's a small, cheap object, replacing it isn't a problem. But when you're talking about airplane wings, crash helmets and expensive smartphones, it's a completely different story.

That's why scientists have been working on ways to give inorganic objects the ability to heal. Self-healing plastic has been around since 2001, and last year scientists came up with a self-healing polymer. That's great, but researchers at the University of Bristol have just cracked (pun intended) the biggest advance yet.
