A treasure-trove of formerly classified data on the thickness of sea ice in the Arctic Ocean, gathered by U.S. Navy submarines over several decades, is now being opened. Data from the first of approximately 20 cruise tracks -- an April, 1992 trans-Arctic Ocean track -- has just been released, and information from the rest of these tracks, or maps of a submarine's route, will be analyzed and released over the next year-and-a-half.

Just as a photographer moves a camera to focus on a specific image, the human brain directs the eyes to focus on an image. Although the images we see are often quite complex - an array of colors, textures and shapes - seeing them begins with a process that originates in single brain cells. Vanderbilt psycholgoist Jeffrey D. Schall has spent the past 10 years studying how the brain guids the eyes. For his research, he has been recognized by the National Academy of Sciences.
