Submission + - Vanderbilt University Steps Into the Exoskeleton Market (

Zothecula writes: For people who are unable to walk under their own power, exoskeletons offer what is perhaps the next-best thing. Essentially “wearable robots,” the devices not only let their users stand, but they also move their legs for them, allowing them to walk. While groups such as Berkeley Bionics, NASA, Rex Bionics, and ReWalk are all working on systems, Nashville’s Vanderbilt University has just announced the development of its own exoskeleton. It is claimed to offer some important advantages over its competitors.

Submission + - Could a 'Death Star' really destroy a planet? (

aquabats writes: "Mirroring many late night caffeine-fueled arguments among Sci-Fi fans, a University of Leicester researcher asks the question:
Could a small moon-sized battle station generate enough energy to destroy an Earth-sized planet?
A paper by David Boulderston (University of Leicester) sets out to answer that very question."

Submission + - What do we do when the Internet mob is wrong? (

cornicefire writes: By now everyone has heard the news and seen the picture of the boy who was killed over the new Nike sneakers. There are Facebook pages devoted to fist shaking protests about the materialism and greedy. Yada yada yada. But while the scuffles over the shoes were real, the death was not. The photo was just a stock photo of some kid in a lab. We know this because of some old school reporters — Steve Earley and Justin Fentin of the Baltimore Sun. In the rush to celebrate crowdsourcing, many of us pooh-pooh the old media as "gatekeepers" but there are times when the keeping that gate locked is a good idea. After all, if one of the crowd discovered the error, the signal would barely rise above the noise. There are people claiming that anyone questioning the facts is being disrespectful. Is there something we can do about the mobocracy? How can we support the best traditions of journalism while fixing the worst? How can we nurture accuracy?
