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.

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 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.
