When we look at biological cells under a microscope, they’re usually not very colourful. Normally, to visualise them we have to artificially add colour — 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.

A light-powered microscope has a resolution limit of around 200 nanometers—which makes observing specimens smaller or closer together than that all but impossible. Engineers at the University of ...

Researchers at the University of California are working on a technology that is able to enhance the resolution of a standard light microscope, allowing it to directly view finer structures and details ...

If you look at cells from a human or other mammal under a microscope, you’ll see big fat molecular complexes called chromosomes that contain our DNA. If the cells are from a bird or reptile, you’ll ...

Maybe it expressed a sergeant’s snark toward the officer corps. Or a budding scientist’s thrill at a big find. Either way, the hand-lettered label that future Bates professor William H. Sawyer Jr.

Electrical engineers at the University of California San Diego developed a technology that improves the resolution of an ordinary light microscope so that it can be used to directly observe finer ...

Engineers have developed a technology that turns a conventional light microscope into what's called a super-resolution microscope. It improves the microscope's resolution (from 200 nm to 40 nm) so ...
