Alfonso Rodríguez-Baeza and Marisa Ortega-Sánchez (2009). Photomicrograph of the microscopic blood vessels that shuttle oxygen and nutrients to neurons in the brain, obtained with a scanning electron microscope. This sample, from Human cerebral cortex, shows a large blood vessel at the surface of the brain (top), which sends down thin, densely branched capillaries to deliver blood throughout the entire cortex.
The cancer cell's pink mitochondria and gold endoplasmic reticulum--a network of vesicles and sacs--swirl around a dark nucleus. The rendering was awarded an honorable mention in the illustration category of the 2008 International Science and Engineering Visualization Challenge. Donald Bliss and Sriram Subramaniam of the National Institutes of Health's National Library of Medicine created the image by "sandblasting" the cell with ions of the element gallium.
