When we look at biological cells under a microscope, they're usually not very colorful. Normally, to visualize them we have to artificially add color—typically by staining. By doing so, we can see ...

Approximately 145 million: That's the number of specimens—including plants, animals, minerals, and human artifacts—curators estimate are held in the Smithsonian National Museum of Natural History.

1) Microscope slides and coverglass are used in many parts of the lab while knowledge of how these items are made and the technical properties they have is limited. 2) By not understanding the ...

Red dye fills the tiny blood vessels of this tongue tissue. The large, roundish structure in the center of image is a projection on the surface of the tongue known as a fungiform papilla. These ...

Thermal sensing with fine spatial resolution is important to the study of many scientific areas. While modern microscopy systems allow optical detection at high spatial resolution, their intrinsic ...

The ability to image intact tissues at high resolution over large areas or volumetric fields of view, with the same level of morphological and molecular contrast that is possible through conventional ...

To use a light microscope to examine animal or plant cells. To make observations and draw scale diagrams of cells. Turn the coarse focus so that the stage is as close to the objective lens as possible ...
