Coming soon `self-healing` materials

Researchers have discovered that under certain conditions, putting a cracked piece of metal under tension, exerting a force that would be expected to pull it apart, has the reverse effect, causing the crack to close and its edges to fuse together.

Pinecones inspire new material that gets itself into shape

Drawing inspiration from pinecones, which close their scales when wet and open them again once they have dried out, researchers have produced synthetically a composite material with comparable properties.

New polymer can reproduce smooth, rough textures

Perhaps inspired by a chameleon`s changing colours, engineers have developed a polymer that reproduces rough, smooth textures as and when required.
