Cell division. Coloured scanning electron micrograph (SEM) of a neuroglia cell splitting into two new cells (cytokinesis) after mitosis. Mitosis is a form of cell division in which a cell's nucleus splits to form two identical copies of itself. These new nuclei move to opposite parts of the cell, and the cytoplasm between them constricts to leave only a thin bridge (centre), which eventually breaks. Neuroglia cells are supportive cells which make up around half the weight of the central nervous system. Magnification x1500 at 6x7cm size.
About the Artist - Professor P. Motta & D. Palermo
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.
