Researchers have devised optical tweezers made up of laser beams that could be used to manipulate and move tiny atoms to align them to form single molecules. This is a breakthrough and has been done ...

Scanning electron microscopes are the workhorses of imaging structures on the scale of billionths of a meter. Typically, they work by shooting a beam of electrons at the specimen and then detecting ...

Scientists have made the first observation of an unusual class of optical waves called Airy beams. Unlike most types of light waves, Airy beams have the ability to resist diffraction over long ...
