Pi number wheel representation, illustration. 10,000 digits of Pi as a path traced by links between successive digits. Each digit is assigned a segment (0-9). For example, the sequence '14' is drawn as a link between segment 1 and segment 4. The number of transitions between digits is summarized in a series of circles placed outside the links. 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. For a labelled variant of this image, see C038/4613 to C038/4615.

Norovirus, computer illustration. Norovirus is a genus of RNA (ribonucleic acid) viruses (of the family Caliciviridae), which cause about half of all gastroenteritis cases around the world. The disease is characterised by nausea, vomiting, diarrhoea and abdominal pain. The diarrhoea results in fluid loss and dehydration, which may become life-threatening in the young, the elderly, and the immunocompromised if not treated promptly.

Human ovum, or egg, surrounded by numerous spermatozoa, computer illustration. In fertilisation, only a single sperm may successfully penetrate the ovum to fuse with the female nucleus. Barriers to be overcome include layers of follicular cells surrounding the ovum (corona radiata) and an underlying glycoprotein membrane, the zona pellucida. The membrane is digested by enzymes released from the acrosome, a cap on the head of the sperm: subsequent rapid chemical changes in the zona pellucida prevent competing sperm from entering.
