Rainbow trout
The rainbow trout (Oncorhynchus mykiss) is a species of the salmon family native to cold-water tributaries of the Pacific Ocean in Asia and North America. Those that spend their lives in streams and rivers average between 1 and 5 lb (0.5 and 2.3 kg); others, called steelhead trout, live in the ocean or the Great Lakes for two to three years before returning to fresh water to spawn, and may reach 20 lb (9.1 kg). Coloration varies widely, but all adult fish are distinguished by a broad reddish stripe along the lateral line, from gills to the tail, which is most vivid in breeding males. Wild-caught and hatchery-reared forms of this species have been transplanted and introduced for food or sport in at least 45 countries. Introductions to locations in the U.S., Southern Europe, Australia and South America outside the fish's native range have damaged native fish species when the trout has preyed on them, out-competed them, transmitted contagious diseases, or hybridized with closely related species. Some local populations of specific subspecies, or in the case of steelhead, distinct population segments, are listed as either threatened or endangered under the Endangered Species Act. The steelhead is the official state fish of Washington. (Full article...)

Four people standing on a stage with Rock Band instruments, including a keyboard, two guitars, and a drumkit, along with two singers

Eighty-three songs are included in Rock Band 3, a 2010 music video game developed by Harmonix, published by MTV Games and distributed by Electronic Arts. All of these songs were recorded either from master copies or live performances. When Rock Band 3 was first detailed on June 11, 2010, Harmonix announced 22 of the game's songs. The next month, Harmonix used Facebook and Twitter to provide clues about additional songs for both Rock Band 3 and Dance Central, which they then confirmed to be six Rock Band tracks and three Dance Central tracks. During a video interview at the 2010 Gamescom convention, most of the setlist was inadvertently leaked because someone was scrolling through the setlist in the background. Rock Band Network songs are also playable in Rock Band 3. The game's setlist was well-received by video game critics. Eurogamer's Johnny Minkley noted the contrast between it and the heavier style of Guitar Hero: Warriors of Rock's setlist. (Full list...)

Sophienkirche

The Sophienkirche in Dresden, Germany, as presented in a photochrom from c. 1895. Established in 1333 as a Franciscan monastery and chapel, the church stood empty for years after the Protestant Reformation. Restored in 1610 by Sophie of Brandenburg, the church received an organ made by Gottfried Silbermann in the 18th century, and the composer Johann Sebastian Bach performed several of his works there. The church, redesigned during the mid-19th century, was heavily damaged during the bombing of Dresden in 1945, and in 1962 the East German government ordered it destroyed.
