Cell infected with HIV. Coloured scanning electron micrograph (SEM) of HIV particles (yellow) budding from the membrane of a host cell (blue). HIV (human immunodeficiency virus) attacks CD4+ T-lymphocytes (specialised white blood cells), which are crucial in the body's immune system. It enters the cell and makes many copies of itself, which then destroy the cell as they emerge through its membrane. #anatomy #microscope #microscopic #medicine #medical #human

Bdelloidea are microscopic aquatic animals that are related to roundworms

Bdelloidea are microscopic aquatic animals that are related to roundworms, found in freshwater and moist soil. Interestingly, a male has never been observed within the species; females reproduce exclusively by parthenogenesis (without fertilization).

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.

Colored scanning electron micrograph (SEM) of squamous cell carcinoma (cancer) cells from a human mouth. The many blebs (lumps) and microvilli (small projections) on the cells' surfaces are typical of cancer cells.

Fat cell. Coloured scanning electron micrograph (SEM) of an adipocyte (fat cell, blue). Surrounding the adipocyte are white blood cells (red). hip hop instrumentals updated daily => http://www.beatzbylekz.ca

Coloured scanning electron micrograph (SEM) of an adipocyte (fat cell, blue). Surrounding the adipocyte are white blood cells (red). Such a lovely color.

Nerve bundle. Coloured scanning electron micrograph (SEM) of a freeze-fractured section through a bundle of myelinated nerve fibres. Myelin sheaths (yellow) can be seen surrounding the axons (blue). Perineurium (connective tissue, pink) surrounds the nerve bundle while endoneurium divides the individual fibres.

<b>Balancing stone from inner ear</b> (colored scanning electron micrograph)

Game-Changing Discovery Links Brain and Immune System

Our sense of balance is derived from a tiny stone in each ear, called an otolith (from Greek, literally "ear-stone"). The stones are built up in the inner ear from deposits of calcium carbonate crystals, seen here on the surface of an otolith.

Diatom. Coloured scanning electron micrograph (SEM) of a Stephanopyxis sp. diatom.

Just another design miracle! Coloured scanning electron micrograph (SEM) of a Stephanopyxis sp.

Lung cancer cell division.  Coloured scanning electron micrograph (SEM) of a lung cancer cell during cell division (cytokinesis). The two daughter cells remain temporarily joined by a cytoplasmic bridge (centre). Cancer cells divide rapidly in a chaotic, uncontrolled manner. They may clump to form tumours, which invade and destroy surrounding tissues.

This is a scanning electron micrograph (STEM), coloured by Steve Gscheissner, of a lung cancer cell dividing. The two daughter cells remain temporarily joined at the cytoplasmic bridge.
