Researchers are making progress toward a “perfect lens” that will be able to resolve an organelle assembling a protein or a virus attacking a cell. From ribosomes assembling proteins to viruses ...

What makes it distinct from other metamaterials is that it is made entirely from semiconductor material — the stuff found in computer chips and prized for its ability to act as ...

Nearly a decade after getting waves of light to bend backward, physicists have done the same with electrons. Electrons coursing through a sheet of carbon atoms exhibited negative refraction, bending ...

Science seems obsessed with creating tiny objects that can do big things. Like a team at the University of Wisconsin-Madison which has created a new microlens with a 170-degree field of vision.
