We can see objects as small as 0.1 millimeters, and that means we can just about see these lice eggs in our hair and tiny single-celled organisms like amoeba. But it's possible to see things much ...

Biomedical research involves getting a close look at what’s happening inside of cells. Usually, that happens after cells are grown on a glass slide and then fixed in place. They can then be treated so ...

There are several different types of electron microscopes, including the transmission electron microscope (TEM), scanning electron microscope (SEM), and reflection electron microscope (REM.) Each of ...

Electron microscopy is a powerful technique that provides high-resolution images by focusing a beam of electrons to reveal fine structural details in biological and material specimens. 2 Because ...

Mass spectrometry has come into its own as an extremely powerful tool for the study of whole proteomes. So why are not more cell biologists embracing it with open arms? The human body has some 20,500 ...

Or more precisely, as neuroscientist Eric Betzig and his colleagues put it in today’s issue of Science: “Every living thing is a complex thermodynamic pocket of reduced entropy through which matter ...

Fundamentally, a microscope comprises two subsystems: an illumination system to illuminate the sample and an imaging system that produces a magnified image of the light that has interacted with the ...

Which stereo microscopes are best? Depending on how you plan to use it, finding the best stereo microscope for your needs can actually make a huge difference. However, making sense of the various ...

An engineer at Stanford University has created a DIY microscope, called the Foldscope, that is fashioned out of a single piece of printed-and-folded A4 paper, origami-style. This paper-based ...
