To study living organisms at ever smaller length scales, scientists must devise new techniques to overcome the so-called diffraction limit. This is the intrinsic limitation on a microscope's ability ...

For the first time, researchers have shown that terahertz imaging can be used to visualize internal details of the mouse cochlea with micron-level spatial resolution. The non-invasive method could ...

Cells are tiny, so we use microscopes to see their details. A slide is a thin piece of glass used to hold objects which are examined under a microscope. Peel a thin layer of cells from an onion. Place ...
