Stretching protein samples in all directions pulls molecules farther apart, allowing them to be visualized using only light ...

Hosts of new applications have turned the light microscope into an exquisitely sensitive measuring device that can be used to image dynamic cellular events right down to the molecular level. Indeed, ...

A laser (purple) is powerfully amplified by highly polished mirrors and focused on the electron beam (blue) to shift its ...

Imagine owning a camera so powerful it can take freeze-frame photographs of a moving electron—an object traveling so fast it could circle the Earth many times in a matter of a second. Researchers at ...

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 ...

Constructed with an LCD digital display, multiple lenses and XY stage plate navigation, the Celestron PentaView feels professional, enables specimens to be viewed by a large audience and is an ...

Our brain is a complex organ. Billions of nerve cells are wired in an intricate network, constantly processing signals, enabling us to recall memories or to move our bodies. Making sense of this ...

In biology, seeing can lead to understanding, and researchers in Professor Edward Boyden's lab at the McGovern Institute for Brain Research are committed to bringing life into sharper focus. With a ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

In 1931, physicists Knoll and Ruska unveiled the first electron microscope, revolutionizing science by using magnetic lenses ...
