Scanning Electron Micrograph

Moss spore capsule (Tortula muralis var. muralis). Coloured scanning electron micrograph (SEM) of part of the opening mouth of a capsule (spore case) of moss. Mosses reproduce by means of spores at certain times during their life cycle. The spores are dispersed from the mouth of the capsule, dispersal aided by the wind. Magnification x1380

Wellcome Image Awards 2011: Life as you've never seen it before - in pictures

Moth wing scales Kevin Mackenzie, University of Aberdeen Scanning electron micrograph (SEM) of the scales on the wing of a Madagascan moon moth, Argema mittrei. This moth is also known as the Comet moth, after its very long tail. The tail span is 15 cm and wing span 20 cm, making it one of the world's largest silk moths.

Ask Well: Ebola on Airplanes, Ebola in Sneezes

This digitally-colorized scanning electron micrograph (SEM) depicts a single filamentous Ebola virus particle that had budded from the surface of a VERO cell of the African green monkey kidney epithelial cell line under a very-high magnification. Produced by the National Institute of Allergy and Infectious Diseases (NIAID). See:


Retina. Coloured scanning electron micrograph (SEM) of rods (yellow) and cones (green) in the retina of the eye. The outer nuclear layer is purple. Magnification x1800 when printed at 10 centimetres wide. [F0010041] Incredible!!


Blood clot. Coloured scanning electron micrograph (SEM) of a blood clot from the inner wall of the left ventricle of a human heart. Red blood cells (erythrocytes) are trapped within a fibrin protein mesh (cream). The fibrin mesh is formed in response to chemicals secreted by platelets (pink), fragments of white blood cells. Clots are formed in response to cardiovascular disease or injuries to blood vessels. Connective tissue (orange) is also seen.


Fat tissue. Coloured scanning electron micrograph (SEM) of a sample of fat tissue, showing fat cells (adipocytes, blue) surrounded by fine strands of supportive connective tissue. Adipocytes are among the largest cells in the human body, each cell being 100 to 120 microns in diameter. Almost the entire volume of each fat cell consists of a single lipid (fat or oil) droplet. Adipose tissue forms an insulating layer under the skin, storing energy in the form of fat, which is obtained from…
