Manipulating wrinkles could lead to graphene semiconductors

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 ...

Mathematical models explain how a wrinkle becomes a crease

Wrinkles, creases and folds are everywhere in nature, from the surface of human skin to the buckled crust of the Earth. They can also be useful structures for engineers. Wrinkles in thin films, for example, can help make ...

Teaching complete evolutionary stories increases learning

Many students have difficulty understanding and explaining how evolution operates. In search of better ways to teach the subject, researchers at Michigan State University developed complete evolutionary case studies spanning ...

Science gets a grip on finger wrinkles

Getting "pruney fingers" from soaking in the bath is an evolutionary advantage, for it helps us get a better grip on objects under water, scientists suggest.

Wrinkled surfaces could have widespread applications

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 ...

The older we get, the less we know (cosmologically)

(Phys.org) -- The universe is a marvelously complex place, filled with galaxies and larger-scale structures that have evolved over its 13.7-billion-year history. Those began as small perturbations of matter that grew over ...
