A new kind of microscope is giving scientists a way to watch life inside cells with a clarity that feels almost unfair. Instead of choosing between seeing big structures or tiny particles, researchers ...

A mouse’s heart beats roughly 600 times each minute. With every beat, blood pumping through vessels jiggles the brain and other organs. That motion doesn’t trouble the mouse, but it does pose a ...

For centuries, biological imaging was myopic; visualization stopped at about 10 μm of tissue depth. Detailed observation of tissue came with a death sentence for the tissue (fixation) so that it could ...

Researchers have shown that consumer-grade 3D printers and low-cost materials can be used to produce multi-element optical ...

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 ...

This type of microscope can achieve a magnification of typically 2-6 x, which is sufficient to study relatively large samples. However, achieving higher magnification and better image quality requires ...

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 ...
