Hairs on leafThe 2005 Novartis and The Daily Telegraph Visions of Science Photographic Awards, supported by the Science Photo Library, produced some colorful and eclectic art-meets-science winners this year. Contest entries came from professors, doctors, researchers, scanning electron microscopists, artists, photographers and students.
This photograph does not portray orange starfish on a rocky seabed, but rather tiny star-shaped hairs on a plant's leaf. The hairs, called trichomes, can help stop insects from feeding on the leaf and prevent some water loss.
Shrimp cleaning teeth

When fish need a cleaning, they approach the anemone in the background, in which the shrimp lives, and open their mouths, encouraging the shrimp in. Both partners benefit.
A rotating amusement park ride at dusk. Passengers on this ride experience a force about twice that of gravity. The force is due to the acceleration felt by the change in direction necessary to keep the passenger moving in a circle at a constant speed. The same force applies to satellites orbiting planets and planets orbiting the sun.
