False-colour scanning electron micrograph (SEM) of the soil bacterium Streptomyces lividans, showing the formation of a spiral spore chain (orange). S. lividans is a natural producer of the antibiotic Streptomycin. A member of the Actinomycetes group, the bacterium shares many characteristics with the fungi. The bacteria grow in the soil as a branching network of filaments, known as a mycelium (yellow). They also produce aerial mycelium, from the tips of which develop spore chains of indefinite length. When spores of the kind shown here are mature, they rupture & are dispersed on the wind. Magnification x6500 at 6x4.5cm size.
Science Photo Library was founded in 1981 by Michael Marten, one of the authors of "Worlds Within Worlds", a book exploring different ways to observe the universe - from electron micrographs, to images of earthrise taken from the Apollo spacecraft. When Marten started receiving requests for the beautiful images in the book, he had an idea of setting up Science Photo Library.
Since then, Science Photo Library has continued to work alongside world acclaimed photographers and the leading science and medical experts to provide a central source of the best science and specialist imagery available. Although the collection started with scientific images, it has grown to encompass all aspects of science and their impact on everyday life.
