Sodium valproate drug, molecular model. This drug, marketed under dozens of brand names worldwide including Depacon and Epilim, is the sodium salt of valproic acid. It is an anticonvulsant used to treat epilepsy, but can also be used in the treatment of bipolar disorder as a mood stabiliser. It increases the activity of the inhibitory GABA neurotransmitter in the brain, thus stabilising brain activity. This prevents the build-up of electrical signals that causes fits. Atoms in this model are represented by coloured spheres; carbon is turquoise, hydrogen is white, oxygen is yellow, and sodium is purple.
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.
