Graphene Could Make Magnetic Memory 1000x Denser 123

KentuckyFC writes "The density of magnetic memory depends on the size of the magnetic domains used to store bits. The current state-of-the-art uses cobalt-based grains some 8nm across, each containing about 50,000 atoms. Materials scientists think they can shrink the grains to 15,000 atoms but any smaller than that and the crystal structure of the grains is lost. That's a problem because the cobalt has to be arranged in a hexagonal close packing structure to ensure the stability of its magnetic field. Otherwise the field can spontaneously reverse and the data is lost. Now a group of German physicists say they can trick a pair of cobalt atoms into thinking they are in a hexagonal close packing structure by bonding them to a hexagonal carbon ring such as graphene or benzene. That's handy because the magnetic field associated with cobalt dimers is calculated to be far more stable than the field in a cobalt grain. And graphene and benzene rings are only 0.5 nm across, a size that could allow an increase in memory density of three orders of magnitude."

First Electronic Quantum Processor Created 205

ScienceDaily is reporting that the first rudimentary solid-state quantum processor has been created by a team led by Yale University researchers. "Working with a group of theoretical physicists led by Steven Girvin, the Eugene Higgins Professor of Physics & Applied Physics, the team manufactured two artificial atoms, or qubits ('quantum bits'). While each qubit is actually made up of a billion aluminum atoms, it acts like a single atom that can occupy two different energy states. These states are akin to the '1' and '0' or 'on' and 'off' states of regular bits employed by conventional computers. Because of the counterintuitive laws of quantum mechanics, however, scientists can effectively place qubits in a 'superposition' of multiple states at the same time, allowing for greater information storage and processing power."

Lenovo Tinkers With Larger Delete and Escape Keys 586

Slatterz writes "After a year's research, Lenovo boffins have decided the time is right to install larger Delete and Escape keys on their updated ThinkPad laptop T400s range. While it is a small change, it is fairly radical to tinker with an area of hardware which has been largely unchanged since the 19th century. What convinced them to make the size-change was doing some tests on users to see which keys they use the most. They found that on average, people used the Escape and Delete keys 700 times per week, yet those were the only non-letter keys that Lenovo hasn't made any bigger." The article says Caps Lock may be next on the agenda; death is too good for Caps Lock.

Desktop As a Cellphone Extension? 199

spaceman375 writes "Like many slashdotters, I've given up on landlines and have only a cell account. The problem: when I am home I don't want to carry my phone on my person, AND I don't want to have to run (possibly up or down stairs) to answer a call. Landlines solved this with extensions. I could go buy an xlink or other Bluetooth-to-POTS solution, but that takes money for equipment. My desktop has Bluetooth, as do my laptop and cell. All I want is a program that can use my cell's Bluetooth to make and receive calls from my Linux PC. I can do this with asterisk or related programs, but that is like buying UPS when I just need a taxi ride. Yet all I can find are programs that either use 'presence' to shift other-sourced calls to my cell, or ways to use a Bluetooth headset when receiving a call on a PC. Has anyone found a way to use their desktop to make and receive calls through their cell via Bluetooth?"

I'm not quite dumb enough to drive off a cliff, but something that doesn't even try and lead me to watery doom is preferable. The only thing I absolutely must have is the ability to hack it. It would be preferable if it ran GNU/Linux, but given a convincing argument, I would be swayed to another OS. Without wanting the Moon on a stick, what is the best device that would offer a decent modding community and a good feature set?"

DARPA Wants a 19" Super-Efficient Supercomputer 200

coondoggie writes "If you can squish all the processing power of, say, an IBM Roadrunner supercomputer inside a 19-inch box and make it run on about 60 kilowatts of electricity, the government wants to talk to you. The extreme scientists at the Defense Advanced Research Projects Agency this week issued a call for research that might develop a super-small, super-efficient super beast of a computer. Specifically, DARPA's desires for Ubiquitous High Performance Computing (UHPC) will require a new system-wide technology approach including hardware and software co-design to minimize energy dissipation per operation and maximize energy efficiency, with a 50GFLOPS per watt goal."

Microsoft To Offer Windows 7 On USB Thumb Drives? 259

Barence writes "Microsoft is reportedly considering offering Windows 7 on USB thumb drives to allow netbook owners to upgrade their machines. Windows has, until now, only been distributed on DVDs or via download. However, netbooks don't have optical drives and the Windows 7 ISO weighs in at 2.3GB, which would take several hours to download on an average broadband connection and potentially do serious damage to a customer's broadband data cap."

Smartphones Get "Reality Overlay" App 110

Michael_Curator writes to tell us that mobile phones now have a "reality overlay" app that combines a smartphone's camera, GPS, and compass to augment a user's view of a particular location with metadata. "It works as follows: Starting up the Layar application automatically activates the camera. The embedded GPS automatically knows the location of the phone and the compass determines in which direction the phone is facing. Each [commercial] partner provides a set of location coordinates with relevant information which forms a digital layer. By tapping the side of the screen the user easily switches between layers."

New Lithium-Air Battery Delivers 10 Times the Energy Density 281

Al writes "A company called PolyPlus has developed lithium metal-air batteries that have 10 times the energy density of regular lithium-ion batteries. The anode is made up entirely of lithium metal, and the surrounding air acts as the cathode, making the batteries incredibly energy dense. Previous efforts to make lithium metal batteries have been stymied by the sensitivity of lithium to water in the air. The new batteries use a sophisticated membrane to protect the lithium anode and PolyPlus has even created a version that works underwater, by drawing oxygen through the membrane. Lithium metal-air batteries could be light-weight power sources for demand for plug-in hybrid vehicles and consumer electronics; IBM also recently announced that it would develop lithium metal-air batteries for the energy grid and for transportation."

US House May Pass "Cap & Trade" Bill 874

jamie found this roundup on the status of the Waxman-Markey climate change bill, which is about to be voted on by the US House of Representatives. (The article notes that if the majority Democrats can't see the 218 votes needed for passage, they will probably put off the vote.) The AP has put together a FAQ that says, "[The bill, if passed,] fundamentally will change how we use, produce and consume energy, ending the country's love affair with big gas-guzzling cars and its insatiable appetite for cheap electricity. This bill will put smaller, more efficient cars on the road, swap smokestacks for windmills and solar panels, and transform the appliances you can buy for your home." The odds-makers are giving the bill a marginal chance of passing in the House, with tougher going expected in the Senate.

Facebook VP Slams Intel's, AMD's Chip Performance Claims 370

narramissic writes "In an interview on stage at GigaOm's Structure conference in San Francisco on Thursday, Jonathan Heiliger, Facebook's VP of technical operations, told Om Malik that the latest generations of server processors from Intel and AMD don't deliver the performance gains that 'they're touting in the press.' 'And we're, literally in real time right now, trying to figure out why that is,' Heiliger said. He also had some harsh words for server makers: 'You guys don't get it,' Heiliger said. 'To build servers for companies like Facebook, and Amazon, and other people who are operating fairly homogeneous applications, the servers have to be cheap, and they have to be super power-efficient.' Heiliger added that Google has done a great job designing and building its own servers for this kind of use."

Google Funding the Next Big One? 295

Apparently the company, AltaRock, omitted to disclose that the same deep drilling caused a major quake in Basel, Switzerland when it was last used. Given the notorious geological instability of the Northern Californian coast, this strikes me as kind of dumb — and given the known likelihood of this technique producing earthquakes, somewhat EVIL."

Panasonic Begins To Lock Out 3d-Party Camera Batteries 450

OhMyBattery writes "The latest firmware updated for Panasonic digital cameras contains one single improvement: it locks out the ability to use 'non-genuine Panasonic' batteries. It does so for safety reasons, it says. It seems to indicate that this is going to be the norm for all new Panasonic digital cameras. From the release: 'Panasonic Digital Still Cameras now include a technology that can identify a genuine Panasonic battery. For the protection of our customers Panasonic developed this technology after it was discovered that some aftermarket 3rd party batteries do not meet the rigid safety standards Panasonic uses.' The firmware warning is quite clear as to what it does: 'After this firmware update your Panasonic Digital Camera cannot be operated by 3rd party batteries (non genuine Panasonic batteries).'"
