When last we saw [xoreaxeax], he had built a lens-less optical microscope that deduced the structure of a sample by recording ...

The first microscope that uses the eerie trick of quantum entanglement to increase its sensitivity has been developed by Japanese researchers. The new tool relies on a weird principle of quantum ...

Receive emails about upcoming NOVA programs and related content, as well as featured reporting about current events through a science lens. The new microscope uses a 405 nm laser—the same wavelength ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

A new microscope is giving scientists a clearer, more comprehensive view of biological processes as they unfold in living animals. The microscope produces images of entire organisms, such as a ...
