Epidermis. Electron microscope micrograph showing a keratinocyte of spinous layer. The epithelial cell has a polygonal shape, central nucleus with nucleolus, cytoplasm full of keratin filament bundles, and numerous dark desmosomes crossing the intercellular spaces.
Micrograph of amoeba.  Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live animal, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.
Artificial Intelligence: Simplified image of the principles of convolutional neural networks with input, hidden, output layers. It classifies geometric forms - in this case a cube

Deep artificial neural network, schematic structure with layers text labels on white background
Burkitt lymphoma is a form of non-Hodgkin's lymphoma in which cancer starts in immune cells called B-cells. Recognized as a fast growing human tumor, Burkitt lymphoma is associated with impaired immunity and is rapidly fatal if left untreated.
After dopamine binding, the dopamine receptor changes his shape and binds the inactive G protein.The G protein expels its GDP molecule replacing it by GTP. and falls into two pieces. The Galpha subunit binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.

Internal structure of the Earth, cutaway 3D illustration. From the centre outwards, the four layers shown in the image are: inner core, outer core, mantle, and crust
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.
Eye disease, eye cancer, 3d illustration
Christmas background composition with Christmas baubles on white snow.
Isolated lipid bilayer coating mesoporous silica nanoparticle 3d rendering in the background
Image taken with Flir T420 infra red digital camera. Each color represents different temperatures, as is shown on spectrum scale on right side of image.
Amitriptyline is used as an antidepressant and antimigraine drug. It blocks sodium channels on neuronal membrans. Sodium channels generate and propagate action potentials in neurons and muscle. Source: PDB entry 6AGF
