Electric cars are an excellent choice for everyday use, in particular for daily trips in the city. This conclusion is the result of user analyses in two projects in which Siemens plays a decisive role: the internal 4-Sustainelectromobility (4-S) project involving 20 moveE cars and the external "Electromobility Model RegionMunich - Drive eCharged" project involving 40 BMW MINI E cars. The latter is a joint project with BMW Group and Stadtwerke München, Munich's municipal utility.

After six years of intensive effort, scientists are reporting development of the first commercially viable nanogenerator, a flexible chip that can use body movements - a finger pinch now en route to a pulse beat in the future - to generate electricity. Speaking here today at the 241st National Meeting & Exposition of the American Chemical Society, they described boosting the device's power output by thousands times and its voltage by 150 times to finally move it out of the lab and toward everyday life.

After recently undertaking a journey to walk -- not fly -- across the United States in the "Grounded" storyline and reconnect with the country and everyday Americans, Superman appears to be taking another step that could have major implications for his national identity: in Action Comics #900... ...Superman announces that he is going to give up his U.S. citizenship. Despite very literally being an alien immigrant, Superman has long been seen as a patriotic symbol of "truth, justice, and the American way," from his embrace of traditional American ideals to the iconic red and blue of his costume. What it means to stand for the "American way" is an increasingly complicated thing, however, both in the real world and in superhero comics, whose storylines have increasingly seemed to mirror current events and deal with moral and political complexities rather than simple black and white morality.

Web-connected devices, not just mobile phones and 3G tablets but everything from home electronics to consumer packaged goods instrumented to transmit data to the Web, have become a part of every major speech here at the wireless industry's giant conference in Orlando, CTIA. "All devices that can benefit from connectivity will be connected," Hans Vestberg, CEO of Ericsson, said in a keynote, predicting that the world's nearly 5 billion mobile phone subscribers today will be surpassed by 50 billion connected non-phone devices in 10 years.
