Bupropion drug molecule. Computer model of bupropion, an antidepressant and smoking cessation aid, sold under a variety of brand names including Wellbutrin, Zyban and Buproban. As an antidepressant it acts as a norepinephrine and dopamine reuptake inhibitor. This prevents the uptake of these neurotransmitters back into the presynaptic cell, which results in elevated extracellular levels. As a nicotinic antagonist it inhibits nicotine from acting on the nicotine receptors in the brain, therefore preventing it from having a rewarding and enjoyable effect. Atoms, represented as tubes, are colour-coded carbon (yellow), hydrogen (white), nitrogen (blue), chlorine (green) and oxygen (red).
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.
