17th century world map

World map, published around 1664 in Amsterdam, the Netherlands, by Dutch mapmaker Joan Blaeu (c.1599- 1673). The Latin title is Nova et Accuratissima Totius Terrarum Orbis Tabula (new and accurate all world map). Blaeu's maps built on those made by Mercator and Hondius in the late 16th and early 17th centuries. The Blaeu maps emphasized fine art and colours, being the most expensive of the time. Two mapmakers are shown at upper right and upper left, together with a wide variety of mythical beings. The poorly-mapped regions include the far north and south, parts of the Americas (left-hand hemisphere), and the Far East. The western coast of Australia (New Holland) was discovered in 1616

Potato blight on leaf

Potato blight on leaf. Coloured scanning electron micrograph (SEM) of the potato blight fungus Phytophthora infestans, emerging from a potato leaf. Here, sporangiophores (dark green) are seen growing from the lip-like stomata on the underside of the leaf. Sporangiophores are hyphae, or filaments, which carry sporangia (spore sacs, brown). Leaf hairs, or trichomes, are the large green/yellow structures. The first widespread infection of commercial importance was in 1845, when most of Europe suffered decimated potato crops due to blight. Prevention of blight depends on spraying with fungicide and selective breeding. Magnification: x140 at 5x7cm size. x550 at 4.5x10ins
