Piezo Crystals Harness Sound To Generate Hydrogen 187

MikeChino writes "Scientists at the University of Wisconsin-Madison have discovered that a mix of zinc oxide crystals, water, and noise pollution can efficiently produce hydrogen without the need for a dirty catalyst like oil. To generate the clean hydrogen, researchers produced a new type of zinc oxide crystals that absorb vibrations when placed in water. The vibrations cause the crystals to develop areas with strong positive and negative charges — a reaction that rips the surrounding water molecules and releases hydrogen and oxygen. The mechanism, dubbed the piezoelectrochemical effect, converts 18% of energy from vibrations into hydrogen gas (compared to 10% from conventional piezoelectric materials), and since any vibration can produce the effect, the system could one day be used to generate power from anything that produces noise — cars whizzing by on the highway, crashing waves in the ocean, or planes landing at an airport."

Dying Man Shares Unseen Challenger Video 266

longacre writes "An amateur video of the 1986 Space Shuttle Challenger explosion has been made public for the first time. The Florida man who filmed it from his front yard on his new Betamax camcorder turned the tape over to an educational organization a week before he died this past December. The Space Exploration Archive has since published the video into the public domain in time for the 24th anniversary of the catastrophe. Despite being shot from about 70 miles from Cape Canaveral, the shuttle and the explosion can be seen quite clearly. It is unclear why he never shared the footage with NASA or the media. NASA officials say they were not aware of the video, but are interested in examining it now that it has been made available."

Novell Bringing .Net Developers To Apple iPad 315

GMGruman writes "Paul Krill reports that Apple's new iPad could be easier to write apps for, thanks to Novell's MonoTouch development platform, which helps .Net developers create code for the iPad and fully comply with Apple's licensing requirements — without having to use Apple's preferred Objective-C. This news falls on the footsteps of news that Citrix will release an iPad app that lets users run Windows sessions on the iPad. These two developments bolster an argument that the iPad could eventually displace the netbook."

Has Apple Created the Perfect Board Game Platform? 531

andylim writes "recombu.com is running an interesting piece about how Apple has created a 'Jumanji (board game) platform.' The 9.7-inch multi-touch screen is perfect for playing board games at home, and you could use Wi-Fi or 3G to play against other people when you're on your own. What would be really interesting is if you could pair the iPad with iPhones, 'Imagine a Scrabble iPad game that used iPhones as letter holders. You could hold up your iPhone so that no one else could see your letters and when you were ready to make a word on the Scrabble iPad board, you could slide them on to the board by flicking the word tiles off your iPhone.' Now that would be cool."

Net Users In Belarus May Soon Have To Register 89

Cwix writes "A new law proposed in Belarus would require all net users and online publications to register with the state: 'Belarus' authoritarian leader is promising to toughen regulation of the Internet and its users in an apparent effort to exert control over the last fully free medium in the former Soviet state. He told journalists that a new Internet bill, proposed Tuesday, would require the registration and identification of all online publications and of each Web user, including visitors to Internet cafes. Web service providers would have to report this information to police, courts, and special services.'"

Student Orchestra Performs Music With iPhones 65

A course at the University of Michigan ends with a live concert featuring students using iPhones as instruments. “Building a Mobile Phone Ensemble“ teaches students to code musical instruments for the iPhone, using the Apple-provided software-development kit. Georg Essl, assistant professor of computer science and music, says, "What’s interesting is we blend the whole process. We start from nothing. We teach the programming of iPhones for multimedia stuff, and then we teach students to build their own instruments.”

Copyright and the Games Industry 94

A recent post at the Press Start To Drink blog examined the relationship the games industry has with copyright laws. More so than in some other creative industries, the reactions of game companies to derivative works are widely varied and often unpredictable, ranging anywhere from active support to situations like the Chrono Trigger: Crimson Echoes debacle. Quoting: "... even within the gaming industry, there is a tension between IP holders and fan producers/poachers. Some companies, such as Epic and Square Enix, remain incredibly protective of their Intellectual Property, threatening those that use their creations, even for non-profit, cultural reasons, with legal suits. Other companies, like Valve, seem to, if not embrace, at least tolerate, and perhaps even tacitly encourage this kind of fan engagement with their work. Lessig suggests, 'The opportunity to create and transform becomes weakened in a world in which creation requires permission and creativity must check with a lawyer.' Indeed, the more developers and publishers that take up Valve's position, the more creativity and innovation will emerge out of video game fan communities, already known for their intense fandom and desire to add to, alter, and re-imagine their favorite gaming universes."

Jetman Attempts Intercontinental Flight 140

Last year we ran the story of Yves Rossy and his DIY jetwings. Yves spent $190,000 and countless hours building a set of jet-powered wings which he used to cross the English Channel. Rossy's next goal is to cross the Strait of Gibraltar, from Tangier in Morocco and Tarifa on the southwestern tip of Spain. From the article: "Using a four-cylinder jet pack and carbon fibre wings spanning over 8ft, he will jump out of a plane at 6,500 ft and cruise at 130 mph until he reaches the Spanish coast, when he will parachute to earth." Update 18:57 GMT: mytrip writes: "Yves Rossy took off from Tangiers but five minutes into an expected 15-minute flight he was obliged to ditch into the wind-swept waters."

First Images of Memories Being Made 71

TheSync writes Eurekalert reports that researchers at the Montreal Neurological Institute and Hospital, McGill and UCLA have captured the first image of protein translation that underlies long-term memory formation. A fluorescent protein showed the increased local protein synthesis during memory formation, which requires cooperation between the pre and post-synaptic compartments of the two neurons that meet at the synapse."
