Nancy Kedersha's photographs reveal information critical to the study of cancer, Alzheimer's, and other diseases. After freezing cells with formaldehyde, the Harvard Medical School biologist punches tiny holes in the outer membrane and inserts antibodies - tagged with photosensitive dyes - which attach to cellular components. Using fluorescence microscopy, she captures the stunning interiors. This image - of cancerous cells (red) hiding among healthy lung cells (green) at more than 1,500 times their actual size - and others are included in Hank Whittemore's Your Future Self: A Journey to the Frontiers of Molecular Medicine, published this month by Thames and Hudson (www.wwnorton.com/thames).
