A quantum version of a fractal pattern, known as "Hofstadter's butterfly," has long been predicted, but the new study marks the first time it has been directly observed experimentally in a real ...

A fractal butterfly pattern produced by an unusual configuration of magnetic fields, first predicted almost 50 years ago, has been seen in detail for the first time in a twisted piece of graphene.

A team has used a process known as DNA origami to make electrochemical sensors that can quickly detect and measure biomarkers. Using an approach called DNA origami, scientists at Caltech have ...
