Cover of an old red book on a black background. The book is unfolded. Side view.
Old book journal cover, with worn marbled paper pattern, scuffed leather spine and corner
centropyxis aculeata (amoeboid organism) under the microscope - optical microscope x400 magnification
Squash preparation of onion root tip cells stained to reveal chromosomes, Bright field illumination, light microscopy. This image was taken with the X40 objective lens. Depth of focus is extremely low at this magnification. Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced. The aperture in this image was optimised for contrast and resolution. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
In vitro bacterial culture
Transmission electron microscope micrographs showing the aspect of muscle fiber sarcomere components in longitudinal (below) and transverse (above) sections at the Z-line, I and A bands and H zone
Algae under microscopic view, Diatoms, phytoplankton, fossils, silica, golden yellow

Vacuolar-type ATPase (V-ATPase) is a highly conserved evolutionarily ancient enzyme with remarkably diverse functions in eukaryotic organisms. V-ATPases acidify a wide array of intracellular organelles and pump protons across the plasma membranes of numerous cell types. 3D cartoon and Gaussian surface models, based on PDB 6wm2, white background.
Collage with old papers
Diatoms, algae under microscopic view, phytoplankton, fossils, silica, golden yellow algae
Concentric patterns and textures of Natural Agate slice for background.
Paps smear analysis: Superficial squamous cell, metaplastic squamous cell, koilocytes cell. HPV related change
Photomicrograph of Volvox globator, a green algae in various stages of development. Dark green spots are daughter colonies forming inside of parent colony. Live specimen. Wet mount, 10X objective, transmitted brightfield illumination.
Notoedres cati under the microscope. Notoedric mange, also referred to as Feline scabies, is a highly contagious skin infestation caused by an ectoparasitic and skin burrowing mite Notoedres cati.
Squash preparation of stained onion root tip cells showing various stages of mitosis. Differential interference contrast optics on a Leica microscope, Image taken with the X40 objective lens. Depth of focus is extremely shallow (just a few microns). Differential interference contrast results in an optical slice horizontally through the specimen providing maximum possible resolution at this magnification and good contrast. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
Alternaria spore was zoom by transmission electron microscope. Alternaria is a genus of ascomycete fungi. Alternaria species are known as major plant pathogens.
Besides the strictly-for-book clipping path, there is another to include the dark shadow strip just under page edges at bottom right as well. Larger, lighter shadow area not included.
