Deinonychus dinosaur, illustration. This small raptor reached about 3 metres in length and stood 1.5 metres tall. It was an agile predator that lived between 110 and 100 million years ago, in the Cretaceous period. The large claws, especially the sharp hooked claw of the hind legs, would have been lethal to its prey. Deinonychus had a large brain for its size and may have hunted in packs. Fossils of this dinosaur have been found in western North America.

Gene mapping, conceptual image. HIPMap (high-throughput imaging position mapping) accurately determines the position of a gene in the three-dimensional (3D) space of the cell nucleus. In this illustration, images of genes (red, green, and blue spots within the nuclei of HeLa cells) are artificially superimposed on images of multi-well plates.

Pi frequency distribution representation, illustration. Frequency distribution of digits in Pi for the first 4,988 digits of Pi in groupings of 4. The layout is 29 columns and 43 rows. The first digit (3) is offset to the top left. For each grouping the number of times a digit was seen is proportional to the width of the ring. Pi (the sixteenth letter of the Greek alphabet) is the symbol used in mathematics to represent the constant of the ratio of the circumference of a circle to its diameter. It is a crucial element of periodic functions and is found in many formulae in trigonometry and geometry. The value of this ratio is approximately 3.14159. It has been calculated to over one trillion digits beyond its decimal point, though as an irrational and transcendental number it continues infinitely without repetition or pattern.

Kidney longitudinal section. Light micrograph of a vertical section through a whole kidney. The kidney is surrounded by a capsule (outer layer) under which is the cortex (purple) consisting mainly of blood vessels and the filtering units (Bowman's capsules). The central medulla (pink) is made up of tubes conveying urine to the medullary pyramids, which open into the renal pelvis (centre right). From here, urine drains into the ureter and to the bladder. This specimen is from a mammal.

Map of climactic zones, 13th century. The map (upper right) is labelled in Latin, with the Earth's polar regions marked 'frigida' (cold), with the temperate zones and a 'Mediterranean' equatorial zone also marked. This manuscript page is thought to have been produced in Therouanne in what is now northern France in the later part of the 13th century (after 1277). It consists of tempera colours, pen and ink, gold leaf, and gold paint on parchment. This is the verso of folio 156 from the Ludwig XV 4 collection of manuscripts, held at the J. Paul Getty Museum, Los Angeles, California, USA.

Biblical astronomer Jonicus, 15th-century manuscript. Jonicus (lower right) is claimed by sources to be the fourth son of the biblical patriarch Noah. He is depicted here as the first astronomer, studying the stars and holding a book. This manuscript page was produced in Regensburg, Bavaria, in what is now Germany, in the early years of the 15th century (1400-1410). It is a later version of the earlier 'Chronicle of the World' (Weltchronik) by 13th-century Austrian poet Rudolf von Ems. This page was produced in tempera colours, gold, silver paint, and ink on parchment. This is the recto of folio 12 of this manuscript, held at the J. Paul Getty Museum, Los Angeles, California, USA.

Astronomers in China, 18th-century tapestry. Standing with his hand on the globe at lower left is the Chinese emperor (the Shunzhi Emperor of the Qing dynasty); the bearded man next to him is German Jesuit priest Father Johann Adam Schall von Bell (1592-1666), director of the Imperial Observatory in Beijing. Equipment in use includes a globe, a telescope, and an ecliptic armillary sphere. This tapestry is part of the series 'The Story of the Emperor of China', produced in France by the Beauvais Manufactory under the direction of Philippe Behagle, based on drawings by Guy-Louis Vernansal, Jean-Baptiste Monnoyer and Jean-Baptiste Belin de Fontenay. The tapestry was produced in Beauvais, France, in the period 1697 to 1705. Made from wool and silk, it measures 3.18 by 4.24 metres. It is part of the collections held at the J. Paul Getty Museum, Los Angeles, California, USA.

Cutaneous syphilis. 19th-century artotype portrait of a patient with a form of cutaneous syphilis. This is a circinate papular form of the disease, here given the name 'Syphiloderma Papulosum Circinatum'. Cutaneous syphilis is a symptom of the secondary stage of syphilis, a sexually transmitted (venereal) infection caused by the Treponema pallidum bacterium. About 6 to 12 weeks after infection, secondary syphilis results in a skin rash, headache, fatigue and fever. No effective treatment was available before 1910 and the disease could be fatal. This image, with markings (red) added to highlight the syphilitic lesions, was published in 1881 by US dermatologist George Henry Fox (1846-1937). Photographed by US photographer Oscar G. Mason (1830-1921).

Urine retention. Illustration of an enlarged male bladder caused by acute retention of urine. At centre is the enlarged bladder (red). The overlying muscles are at right, with the surrounding bone structure revealed at left. At lower centre is the prostate gland (red, oval). Urine retention is the inability to empty the bladder or difficulty in doing so. It may be due to bladder stones, phimosis (tight foreskin), or prostate tumour. A catheter may be used to drain the bladder, before treating the underlying condition.

Angina pectoris. Illustration of the heart and its blood vessels in a case of angina pectoris. This condition is where the heart muscle does not receive enough blood. Pain is felt in the chest radiating towards the neck, right shoulder, right side, and down the left arm. The partially sectioned coronary artery on the heart shows atheroma deposits (yellow) due to atherosclerosis. This is the left anterior descending artery. It is this blockage of the coronary arteries that reduces the blood supply and causes angina pectoris. In severe cases, it can lead to a heart attack.
