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 ...

Nearly 100 years ago, a seemingly simple discovery revolutionized the microscope. The introduction of phase contrast, which ...

Electron microscopy (EM) has become an indispensable tool for investigating the nanoscale structure of a large range of materials, across physical and life sciences. It is vital for characterisation ...

Fifteen years ago, physicists worked out a method to increase image contrast by hitting the electron imaging beam with an ...

Scientists have known for decades that opioids relieve pain by binding to molecular switches in the brain called mu-opioid receptors. What they didn't know—until now—was exactly what happens next. A ...

Cells are tiny, so we use microscopes to see their details. A slide is a thin piece of glass used to hold objects which are examined under a microscope. Peel a thin layer of cells from an onion. Place ...
