Charles Darwin Featured February Print

Charles Darwin

Portrait of Charles Robert Darwin (1809-1882) English naturalist and author of the Origin of Species aged about 65 years. He suggested that natural variation in a species creates a wide range of individual characteristics, some of which are more useful than others. The competition to survive in nature provides a driving force for evolution in the form of natural selection, a mechanism which weeds out those individuals possessing traits less suitable to the environment. The implications of his theory to man's own origins fuelled a bitter controversy with Christian orthodoxy. Black and white photograph 1874: coloured in 1995

Coloured SEM of a dust mite, Dermatophagoides sp Featured February Print

Coloured SEM of a dust mite, Dermatophagoides sp

Dust mite. Coloured Scanning Electron Micrograph (SEM) of a dust mite Dermatophagoides sp., in a sample of household dust. It is crawling among hair, fibres and other dust debris. This mite is a cause of dermatitis (skin inflammation) and is implicated as a cause of asthma. Every house has millions of tiny dust mites, living in carpets and furniture and feeding on the flakes of skin shed by their human landlords. The average double bed contains about two million dust mites of various species. The body of the mite is made up of three regions: gnathosoma (head, centre right); propo- dosma (with first two pairs of legs); hysterosoma (abdomen).

Artwork of arteriole dilated by alpha-blocker drug Featured February Print

Artwork of arteriole dilated by alpha-blocker drug

Dilated arteriole. Artwork of an arteriole (small artery) dilated by an alpha-blocker drug given to treat hypertension - abnormally high blood pressure. The large red cells are red blood cells. The smaller blue cells are platelets, which play a role in blood clotting. The arteriole's outer muscular wall is dark pink. Its inner membrane is light pink. Nerves are shown in blue and yellow. Hypertension increases the risk of heart disease and stroke. Alpha-blockers relieve the condition by blocking the signals from nerves that make arterioles constrict. As a result the arteriole dilates (vasodilation), improving peripheral blood flow and reducing blood pressure
