UK researchers shows highest-resolution optical microscope ever

Scientists form the UK have demonstrated the highest-resolution optical microscope ever, aided by tiny glass beads.

The microscope is so powerful that imaged objects down to just 50 billionths of a metre to yield a never-before-seen.

The team says the method could even be used to view individual viruses.

Their technique, reported in Nature Communications, makes use of "evanescent waves", emitted very near an object and usually lost altogether.
