This is a snapshot of an atomic simulation in progress. Boomerang-shaped water molecules slip as they march single file through the narrow pore of the gold aquaporin, while the red balls and fibers that make up the cell's membrane keep the outside water (top) from mixing with the cellular pool (bottom).

X-ray crystallographic data was used from real DNA molecules to paint a unique portrait of the double helix. The image omits the chemical bonds that crisscross the center of the molecule, so that the structural features of the helix, such as the major and minor grooves, can be seen more easily.

This graphic cuts to the core of one of the world's most unusual volcanoes in Mt. Etna. The image merges the latest scientific data with state-of-the-art 3D modeling software to give a comprehensive view of the volcano's rich and violent history.
