Activated platelet, coloured scanning electron micrograph (SEM). Platelets, or thrombocytes, are fragments of white blood cells. When blood clots, red blood cells (erythrocytes) are trapped within a fibrin protein mesh, which is formed in response to chemicals secreted by the platelets. Magnification: x15000 when printed at 10 centimetres tall.

A original analog leafstamp of a white wine vine. The perfect gift for the wintner, gardener and nature leaves lover.

Sea slug (Coryphella polaris), from the white sea, Russia.

X and Y chromosomes, coloured scanning electron micrograph (SEM). Humans have 46 chromosomes in total: 23 inherited from the mother and 23 from the father. These sex chromosomes determine the individual's gender. Males have an X sex chromosome (pink) and a Y sex chromosome (blue) and females have two X sex chromosomes.

Kidney tubule. Coloured transmission electron micrograph (TEM) of a section through a proximal convoluted tubule in the kidney. The proximal convoluted tubules function to reabsorb water, glucose and other small molecules from the filtrate, producing a concentrated urine. The tubules consist of a lumen (interior, white) lined with cuboidal epithelial cells (green). These cells are covered in many finger-like projections known as microvilli, which serve to increase the cells' surface area for reabsorption. The cells' nuclei (brown), which contain the cells' genetic information, are also seen. The reabsorbed molecules move into the interstitial fluid of the kidney and are absorbed back into the blood. The liquid in the tubules passes to th...

California sea lion (Zalophus californianus) pup in coastal waters. California sea lions are found along the west coast of North America. They are gregarious, carnivorous marine mammals that mainly feed on fish and shellfish in shallow coastal waters. Photographed in the Gulf of California, Mexico.

Stem cells. Coloured scanning electron micrograph (SEM) of the surface of a clump of human embryonic stem cells (HESCs), showing surface detail. HESCs are pluripotent, which means that they are able to differentiate into any of the 200 cell types in the human body. The type of cell they mature into depends upon the biochemical signals they receive, though the cells seen here have not been exposed to growth factors. HESCs are being studied as a way to repair damaged tissue in diseases such as diabetes and Parkinson's. These cells were grown in 2005 at the Centre for Life, Newcastle Upon Tyne, UK. Magnification: x2200 when printed 10cm wide.

Egg-yolk jellyfish (Phacellophora camtschatica). This jellyfish is found in cool waters across the world. It feeds on gelatinous zooplankton and smaller jellyfish, which become ensnared in its tentacles. Photographed in the western Pacific Ocean, in the Sea of Okhotsk.

Green turtle (Chelonia mydas) swimming by a gorgonian (left) on a coral reef. Green sea turtles are found in warm tropical waters. They are herbivorous, eating algae and sea grasses, and can grow up to 1.5 metres in length. A gorgonian is a coral-like colony of polyps that form a tough structure (red) around themselves for protection and support. Photographed in the Andaman Sea off the coast of Thailand.

Human embryo. Coloured scanning electron micrograph (SEM) of a human embryo at the 16-cell stage on the tip of a pin. The ball of cells (yellow) of the embryo is known as a morula, a cluster of almost identical, rounded cells, each containing a central nucleus. This 16-cell embryo is about three days old. It is at the early stage of transformation from a single cell to a human composed of millions of cells. The cells multiply by repeated cleavage divisions (mitosis) and will form a hollow ball of cells (the blastocyst). Development of the blastocyst occurs before the embryo implants into the wall of the uterus (womb). Magnification: x130 at 6x7cm size. Magnification: x450 at 8x10 inch size.

Bone marrow stem cell. Coloured scanning electron micrograph (SEM) of a stem cell from adult bone marrow in culture. Bone marrow is the tissue found in the hollow interior of bones. It makes several different types of cells, including white blood cells (leucocytes), red blood cells (erythrocytes) and bone cells (osteocytes). Magnification: x4310 when printed 10 centimetres wide.

This "Biohazard Alert" t-shirt provides a warning with an image of a skull wearing a biohazard mask and sporting a frightening biohazard sign on its forehead. With dark colors that create a serious atmosphere, this t-shirt is a visual warning of potential danger and the caution that must be taken. The striking slogan “Biohazard Alert” ensures that the message is conveyed clearly, and this design is not just fashion, but also a serious warning of the potential dangers of biohazards.

American bison (Bison bison) covred in snow. Photographed in Yellowstone National Park, Wyoming, USA, in winter.

Resting T lymphocytes. Coloured scanning electron micrograph (SEM) of resting T lymphocytes from a human blood sample. T lymphocytes, or T cells, are a type of white blood cell and components of the body's immune system. They mature in the thymus. T lymphocytes recognise a specific site on the surface of pathogens or foreign objects (antigens), bind to it, and attract antibodies or cells to eliminate that antigen. Specimen courtesy of Professor Greg Towers, University College London. Magnification: x3000 when printed at 10 centimetres wide.

The Kite Bros. Railway was a subway rail service which privately operated in Raccoon City. It was one of two subway operators in the city, the second being Umbrella USA which operated separately with its own tunnels and stations. It was developed by brothers Oral and Werner Kite in the 1960s, and was opened in April 1969. When it first opened, it ran on only one mile of track, with three stops. Thanks to the "Bright Raccoon 21" plan set up by Mayor Michael Warren, which was funded by Umbrella, the company received enough funding to add another five stations and seven-and-a-half more miles of track.

Biohazard sign design inspired by science fiction and horror.

Brain and spinal cord. Coloured magnetic resonance imaging (MRI) scan of a healthy brain (red) and upper spinal cord (centre to lower centre).

Light microscopy of two renal corpuscles in the kidney. Entering and exiting the corpuscle at one pole are arterioles which form a compact branched mass of capillary loops with red blood cells inside them. These capillaries, known as a glomerulus, provide for a selective filter of blood plasma that circulates through them, constituting the primary mechanism by which the kidney removes waste products from the blood stream that later results in urine production. This initial filtrate also called provisional urine, passes into the gap (Bowman's space) between the glomerulus and the margin of the corpuscle called Bowman's capsule. There may be a million renal corpuscles in each adult human kidney, all of which are developed before birth ther...

Red blood cell, artwork. Section through a human red blood cell (erythrocyte). The upper half of the image shows the blood serum, the lower half shows the erythrocyte. The erythrocyte consists of a cell wall (mauve) and haemoglobin molecules (red) which act as a carrier of oxygen to all parts of the body. The serum contains antibodies (Y-shaped molecules), long thin fibrinogen molecules (light red), albumin (dark yellow), complement C1 (6-armed structures) and lipoprotein (blue).
