Many natural composite materials have evolved to wrinkle in response to certain stimuli: The eye of the squid is lined with wavy layers of silvery reflectors that give it a silvery sheen. In the cell walls of many plants, ...

A team of researchers from the University of Illinois at Chicago, Syracuse University and the University of Pennsylvania, has developed a means for showing how a certain piece of material wrinkles after it has been flattened. ...
Graphene has generally been described as a two-dimensional structure—a single sheet of carbon atoms arranged in a regular structure—but the reality is not so simple. In reality, graphene can form wrinkles which make the ...

An object that's intrinsically flat, say a piece of paper, can be shaped into a cylinder without stretching or tearing it. The same isn't true, however, for something intrinsically curved like a contact lens. When compressed ...

The wrinkles on a raisin result from a simple effect: As the pulp inside dries, the skin grows stiff and buckles to accommodate its shrinking size. Now, a team of researchers at MIT has discovered a way to harness that same ...

Wrinkles and folds are ubiquitous. They occur in furrowed brows, planetary topology, the surface of the human brain, even the bottom of a gecko's foot. In many cases, they are nature's ingenious way of packing more surface ...
