Electron microscopes are some of the most powerful tools in science, allowing us to capture images at a scale so tiny that we can observe individual atoms! Unlike traditional light microscopes ...

Abstract: We present a general method using local intensity information and PCA to detect objects characterized only by that they differ from their surroundings. We apply our method to the problem of ...

When June Almeida peered into her electron microscope in 1964, she saw a round, grey dot covered in tiny spokes. She and her colleagues noted that the pegs formed a halo around the virus—much ...

A close-up microscopic view of MRSA (Methicillin-resistant Staphylococcus aureus) bacteria, a type of staph infection that is resistant to many antibiotics. This video is perfect for educational, ...

A fiery-looking electron micrograph of Varicella zoster virus. Varicella zoster virus (VZV) is a member of the herpes virus family, which commonly causes chickenpox in children, teens, and young ...

Images were recorded digitally with a transmission electron microscope HT-7800 (Hitachi, Tokyo, JP). Enrichment of nigericin-resistant S. aureus S. aureus strain RN450 was grown from 100-fold dilution ...

Cryo-electron microscopy has exposed the structure of a bacterial virus with unprecedented detail. This is the first structure of a virus able to infect Staphylococcus epidermidis, and high ...

Electron microscopy images of monkeypox virus infection in 24-year-old man. Markus Müller, MD a ∙ Barbara Ingold-Heppner, MD b ∙ Hartmut Stocker, MD a ∙ Prof Frank L Heppner, MD c,d,e ∙ Carsten ...

The images also show that covid-19 infection damages the cilia, which are clustered and misshapen in infected cells. It isn’t clear why, as there are no spike proteins on them.

So far, mainly scanning electron microscopy (SEM) has been used to examine cells infected with the virus. With SEM, an electron beam scans the cell and provides an image of the surface structure of ...
