Without the force called friction, cars would skid off the roadway, humans couldn't stride down the sidewalk, and objects would tumble off your kitchen counter and onto the floor. Even so, how ...

For nearly 200 years, scientists clung to a simple idea: ice is slippery because pressure or friction melts its surface, ...

Chemists and physicists shed light on a crucial aspect of friction: how things begin to slide. Using fluorescence microscopy and dedicated fluorescent molecules, they are able to pinpoint how and when ...

The friction on a graphene surface can be dynamically tuned using external electric fields, according to researchers. The friction on a graphene surface can be dynamically tuned using external ...

As man voyages farther toward the stars, and faster across the face of his own earth, the instruments by which he steers become vastly more important. And on planes or ships or spacecraft, the heart ...
