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.

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 ...

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 ...

Scientists at the Smithsonian National Museum of Natural History have developed methods to digitize microscope slides, revealing billions of microfossils previously uncounted in collections. The ...

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 ...

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 ...

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 ...

In the not-so-distant future, there will be a new kind of microscope on the market. One that can easily fit in a backpack or purse and zoom in up to 1,000 times, making it possible for pretty much ...

Victorians were also fascinated by Egyptian mummies. They were collected avidly and even unwrapped at events. Not surprisingly, mummies also found their way under the microscope. These slides contain, ...
