Light--and all waves--can bend around the corners of obstacles found along its path. Because of this phenomenon, called diffraction, it is impossible to focus light onto a spot that is smaller than ...

A group at Yale University has successfully captured 3D super-resolution images from the brains of living mice. As published in Optica, the breakthrough was based on the use of stimulated emission ...

Visualizing subcellular structures deep inside the brains of living animals could improve our understanding of how neurons function in their native environment. Thanks to an improved super-resolution ...
