Friction is an important fact of life, robbing efficiency from anything where two surfaces interact with each other, such as engines and wheels. Lubrication can reduce the amount of friction, but it's never possible to get rid of it entirely.
In some rare cases, however, it's been possible to get the coefficient of friction to drop dramatically. A phenomenon called superlubricity occurs when two perfectly flat surfaces with incompatible crystal structures slide past each other. It's only been observed in extremely small samples, however, as larger surfaces have imperfections that tend to get stuck as they slide around.
Now, researchers have managed to create superlubricity in a large sample. They do so by getting graphene to wrap around nanoscopic diamonds, creating something akin to tiny ball bearings.

These three new images of huge filamentary structures of gas and dust from ESA’s Herschel space observatory reveal how matter is distributed across our Galaxy, the Milky Way.
Large spiral galaxy NGC 4945 is seen edge-on near the center of this cosmic galaxy portrait. In fact, NGC 4945 is almost the size of our own Milky Way Galaxy. Its own dusty disk, young blue star clusters, and pink star forming regions standout in the sharp, colorful telescopic image. About 13 million light-years distant toward the expansive southern constellation Centaurus, NGC 4945 is only about six times farther away than Andromeda, the nearest large spiral galaxy to the Milky Way. Though the galaxy's central region is largely hidden from view for optical telescopes, X-ray and infrared observations indicate significant high energy emission and star formation in the core of NGC 4945. Its obscured but active nucleus qualifies the gorgeous island universe as a Seyfert galaxy and home to a central supermassive black hole.Topological insulators are an unusual class of materials, which do not conduct electricity in their insulating interiors but
