Nerve cell culture. Coloured scanning electron micrograph (SEM) of new growth from a cultured sample from a spinal cord. The numerous branching strands are neurites, processes growing out of the nerve cell body (not seen). These connect to other neurites from other nerve cells, forming a network of nervous tissue. A neurite is either an axon or a dendrite, the former transmitting nerve impulses away from the nerve cell body, while the latter transmits nerve impulses towards the nerve cell body. Research into curing spinal paralysis, uses nerve tissue cultures to investigate methods of promoting neurite growth and neural regeneration. Magnification unknown.
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.
