Light derails electrons through graphene

The way electrons flow in a material determines its electronic properties. For example, when a voltage is sustained across a conducting material, electrons start flowing, generating an electrical current. These electrons ...

Quantum imaging: Pushing the boundaries of optics

Quantum mechanically entangled light particles break down the boundaries of conventional optics and allow a glimpse into previously invisible wavelength ranges, thus bringing about new possibilities for imaging techniques, ...

New holographic camera sees the unseen with high precision

Northwestern University researchers have invented a new high-resolution camera that can see the unseen—including around corners and through scattering media, such as skin, fog or potentially even the human skull.

Thin, large-area device converts infrared light into images

Seeing through smog and fog. Mapping out a person's blood vessels while monitoring heart rate at the same time—without touching the person's skin. Seeing through silicon wafers to inspect the quality and composition of ...

'Yellowballs' offer new insights into star formation

A serendipitous discovery by citizen scientists has provided a unique new window into the diverse environments that produce stars and star clusters, revealing the presence of "stellar nurseries" before infant stars emerge ...
