Solar-powered sea slug harnesses stolen plant genes - life - 24 November 2008 Video: Watch a sea slug eat algae to nab some of its chloroplasts, and the genes that keep them functioning It's the ultimate form of solar power: eat a plant, become photosynthetic. Now researchers have found how one animal does just that. Elysia chlorotica is a lurid green sea slug, with a gelatinous leaf-shaped body, that lives along the Atlantic seaboard of the US. What sets it apart from most other sea slugs is its ability to run on solar power. Solar System, Solar System Information, Facts, News, Photos Our Cosmic Neighborhood From our small world we have gazed upon the cosmic ocean for thousands of years. Ancient astronomers observed points of light that appeared to move among the stars. Apollo 11-17 First man on the Moon - Apollo Moon Landings - QTVR photos from panoramas.dk Less known is that during all the missions they made image sequences which with today's computer technics can be stitched together into 360o interactive panoramas giving you the possibility to view the moon almost as you were there. Many of these panoramas have been published before but in low resolution and displayed in small sizes. Film used on the Moon was a modified Kodak Ectachrome 160.

Modern Art Movement Timeline This French painting movement began when avant-garde artists including Cézanne, Renoir, and Manet scandalized the art world after being refused admission to the official art salon. Turning away from the stress on clarity of form and realistic rendering, the French Impressionists had an interest in how visual perception was based in fleeting optical impressions. They sought new ways to capture light and movement, atmosphere, and weather. They loosened their brushwork and lightened their palettes to include pure, intense colors – especially in their landscapes. Mars: The Mission On the evening of January 3, 2004, Spirit is scheduled to land on Mars. Here's a step-by-step guide to what will happen.

MARS Rover Virtual Reality Panoramic images - 360 degree QTVR Photos from panoramas.dk A Great Place to Watch the Weather - Dust devils The martian wind sends hundreds of dust devils spinning across the surface of the planet. From Spirit's high perch approximately 90 meters (295 feet) above the surrounding plains, as shown in this image taken from the summit of "Husband Hill," three dust devils are clearly visible in the plains of Gusev Crater. Planetary Scientist Ron Greeley of Arizona State University, Tempe, describes the whirling vortices of wind and dust as "vacuum cleaners" that were first seen in images from the Viking Orbiter in 1985, though their existence was predicted as early as 1964. The largest dust devil in this 360-degree panorama, is one of the closest seen by Spirit. It is about 2 kilometers (1.2 miles) away, about 90 meters (295 feet) in diameter, and 275 meters (902 feet) tall.

Read more The primary goal of Experimental Eye Research is to publish original research papers on all aspects of experimental biology of the eye and ocular tissues that seek to define the mechanisms of normal function and/or disease. Studies of ocular tissues that encompass the disciplines of cell biology, developmental biology, genetics, molecular biology, physiology, biochemistry, biophysics, immunology or microbiology are most welcomed. Manuscripts that are purely clinical or in a surgical area of ophthalmology are not appropriate for submission to Experimental Eye Research and if received will be returned without review.
