NEC Develops Zero Standby Power Semiconductor Tech

NEC and a researcher from Japan’s Tohoku University, Professor Hideo Ohno, are working on a power chip that solves a pretty big problem: completely eliminating electricity consumption of electronic devices that are in standby mode. The key piece of technology here is CAM, the world’s first content addressable memory.

This non-volatile memory will be built into the control circuits of TVs, computers and other devices and stores data even when the power is turned off. In other words, constant standby power to maintain data will not be needed anymore (the English press release goes into more technical detail). The picture above shows a prototype power chip.

NEC plans to showcase the tech at a symposium in Kyoto this Friday. The company said it expects it will take up to five years until we can see the technology put to practical use.

PhoneIt-iPad available via Cydia now, claims it’ll turn your iPad 3G into a phone (video)

They hacked Facetime onto the iPhone 3GS, and now they’ve done it again — the iPhoneIslam team’s bringing cellular calling and texting to your jailbroken iPad 3G. We haven’t been able to test it for ourselves quite yet, but the new PhoneIt-iPad app should be available through the team’s Cydia repository right now, and it’ll cost $20 to bring out the full potential of your slate. And with that, it’s only a matter of time before iPad sidetalking becomes a meme.

Underwater Spider Spins Itself an Aqualung

sciencehabit writes “In the ponds of northern Europe lives a tiny brown spider with a bubble on its back. The 10-millimeter-long Argyroneta aquatica is the only spider in the world that spends its entire life underwater. But just like land spiders, it needs oxygen to breathe. So every so often, it leaves its underwater web home to visit the surface and brings back a bubble of air that sticks to its hairy abdomen. It deposits the bubble into a little silk air tank spun for the purpose. This ‘diving bell,’ researchers have now found, is not just a repository. It’s actually a gill that sucks oxygen from the water, allowing the spider to stay under for up to 24 hours.”

Tom's Hardware Dissects Ubuntu 11.4's Interface and Performance

An anonymous reader links to an exhaustive look at the latest Ubuntu, running at Tom’s Hardware. “The new Unity interface is broken down into its individual elements and explained ad nauseam. Overall the article is objectively balanced, the author does a good job of pointing out specific design flaws and shortcomings instead of complaining about how Unity doesn’t work for him specifically. The walkthrough of the uTouch gesture language is exciting (wish I had multi-touch), though a full listing of keyboard and mouse shortcuts come in handy, too. Towards the end of the article there are benchmarks between Lucid, Natty with Unity, and Natty with the Classic interface. The performance of the Unity interface isn’t bad at all, but that kernel power issue does rear its ugly head.”

Los Angeles To Turn Off Traffic-Light Cameras

Hugh Pickens writes “The LA Times reports that the Los Angeles Police Commission has voted to kill the city’s controversial red-light camera program, rejecting claims that the system makes streets safer while costing the city nothing. The police department says the cameras help reduce accidents, largely by deterring drivers looking to run red lights or make illegal turns while critics of the technology question officials’ accident data, saying the cameras instead cause rear-end collisions as drivers slam on their brakes and liken the cameras to Big Brother tactics designed to generate revenues. More than 180,000 motorists have received camera-issued tickets since the program started in 2004 but the commission estimates that the program costs between $4 million and $5 million each year while bringing in only about $3.5 million annually. Members of the public who attended the meeting urged the commission to do away with the cameras, which trigger seemingly boundless frustration and anger among drivers in traffic-obsessed LA. ‘It’s something that angers me every time I get in my car,’ says Hollywood resident Christina Heller. ‘These cameras remove our fundamental right in this country to confront our accuser. And they do not do anything to improve safety.'”

NASA's Aquarius Launched To Help Map the Oceans' Salt

oxide7 writes “NASA launched a satellite featuring an brand-new instrument which will be able to measure the saltiness of Earth’s oceans. Data from the Aquarius/SAC-D spacecraft will help scientists understand better the processes that drive ocean circulation and the movement of freshwater around the planet.”
