mcgrew (sm62704) writes "New Scientist is reporting that John Carmack's 'Armadillo Aerospace' has suffered a large setback in the Northrop Grumman Lunar Lander Challenge after one of its two main rockets crashed and burned. 'During the test, Texel lifted off and hovered without incident, then descended again and touched the ground. But it then rose again unexpectedly and began accelerating upward. "Crap, it's going to fly into the crane, I need to kill it," Carmack recalls thinking. He hit the manual shutdown switch, turning off the vehicle's engine in mid-flight. Texel was about 6 metres above the ground and fell like a stone. One of its fuel tanks broke open when it hit the ground, spewing fuel that ignited and engulfed the vehicle in flames. "It made a fireball that would make any Hollywood movie proud," Carmack says.' No one was hurt in the crash, but the vehicle was destroyed."

KentuckyFC writes to tell us that scientists in Italy and the US have designed a new method of retrieving information from quantum memory that could allow them to create "Quantum RAM". "Giovannetti's idea is to send the address down the branching tree of connections in such a way that it only affects one switch at a time. The first address qubit sets a switch at the first branching point to go one way or the other; the second qubit is sent that way and sets the switch at the next branching point, and so on. The total number of entangled quantum systems is smaller, and they are not so susceptible to interference, allowing information to be retrieved from memory intact."

ChainedFei writes "Wired News notes that the Spectrum auction is moving forward, with the FCC placing a minimum bid for the C-block spectrum being offered at $4.6 billion. That, coincidentally, was the amount that Google fronted as a minimum bid to endorse certain open standards for the spectrum being sold. This is essentially a move to shut out smaller possible competitors while also maximizing the money the auction will generate for the grade-A areas of the spectrum. In addition, any single bidder wishing to purchase the entirety of the spectrum must front a minimum of $10 billion. 'According to the FCC, nearly all of that C block aggregate reserve price will go toward a package of U.S. national licenses. This portion of the spectrum also happens to be the one with two open access conditions attached to its sale mandating that all devices be allowed to access the band and that all applications can be able to run across the network. If the reserve price isn't met, the auction will be rerun without these two conditions in place, according to the FCC.'"

modapi writes "According to the EPA, data centers — not including Google et al. — are on track to double power consumption in the next five years, to 3% of the US energy budget. That is a lot of expensive power. Can we cut the power requirement? We could, if we had a reliable way to benchmark power consumption across architectures. Which is what JouleSort: A Balanced Energy-Efficiency Benchmark (PDF), by a team from HP and Stanford, tries to do. StorageMojo summarizes the key findings of the paper and contrasts it with the recent Google paper, Power Provisioning for a Warehouse-sized Computer (PDF). The HP/Stanford authors use the benchmark to design a power-efficient server — with a mobile processor and lots of I/O — and to consider the role of software, RAM, and power supplies in power consumption."

MojoKid writes "Rumors of a new high-end AMD Athlon 64 X2 chip circulated in July, but availability and specifics of the chip were unconfirmed at the time. Now AMD has officially taken the wraps off their new Athlon 64 X2 6400+, a 3.2GHz dual-core chipset to compete with Intel's Core 2 E6750 and E6850 series. HotHardware notes that the new 6400+ is still built on AMD's 90nm fab process and has a single 2-GHz HyperTransport link and 2 MB of on-chip L2 cache (1 MB per core), just like its predecessor the 6000+. The new processor is said to be a 'channel only' offering and will retail at $239 or so, in a black retail box (picture here) without a heatsink."

amigoro writes "A rocket-powered bionic arm has been successfully developed and tested by a team of mechanical engineers at Vanderbilt University as part of a $30 million military program to develop advanced prosthetic devices for next generation of super-soldiers."

DKC writes "Tech ARP's anonymous source claims that Intel is merely waiting for AMD to release their Barcelona processors before they clobber them with their 45nm die-shrinked processors. In fact, Intel is already producing these 45nm processors at one of their fabs in Arizona. AMD and Intel are in for a long and tough battle ahead. Should be an interesting one though."

News.com has an interesting stroll down memory lane with a look at the "DigiBarn", a collection of technology from early mechanical calculators to modern web appliances. NASA contractor Bruce Damer and partner Alan Lundell run this "museum in transition" from a 19th-century farmhouse deep in the Santa Cruz mountains. In addition to notable success milestones, the company also includes some of the industry failures, like an Apple III Damer acquired from Apple's legal department.

charliezcc writes "My grandmother recently fell and broke two vertebrae (among other things) and is in the hospital while she recovers. Thankfully, she was not paralyzed and retains the use of her limbs. However, they have placed her on a respirator and she is virtually unable to communicate with us, so while we try to keep her company during her recovery, our company is reduced to mainly one-sided conversations. Asking her questions, even yes/no questions, is hard because of the neck brace — it turns into a guessing game and very quickly becomes frustrating for both parties. I'm a firm believer in the power of positive mental attitudes and to make her recovery a little better and I'd like to be able to facilitate two-sided conversations with her so she can keep positive. Keeping in mind that she does not have much technology experience, what would you suggest I utilize to ease the communication barrier? I remember seeing devices with a number of buttons that say whatever you program it to say, but I can't find these anymore. What other kind of devices are available?"

0xdeadbeef writes "BlackBerryCool got a tip that not only was AT&T removing GPS functionality from their version of the BlackBerry 8820, they're doing it so it won't show up the iPhone. While carriers crippling phones to stop them from competing with pay-per-use services is nothing new, this might be the first time they've done it to make their other products seem less diminished."

Gary writes to mention that the U.S. Army recently unveiled a new hybrid-electric propulsion system for use in a new line of manned ground vehicles (MGVs). The new line will have eight different variants, all using the same chassis. The unique feature of the new MGVs is that the traditional engine has been decoupled from the drive train and is used only to recharge the battery and power other systems within the vehicle.

mdsolar writes "In a first for the US, one of three nuclear reactors at the Browns Ferry nuclear plant in Alabama has been shut down because the Tennessee River is too hot to provide adequate cooling for the waste heat produced by the reactor. This is happening as the TVA faces its highest demand for power ever, reports the Houston Chronicle. This effect has been seen in Europe in the past, forcing reduced generation, but the US has until now been immune to the problem. The TVA will buy power elsewhere and impose higher rates, blaming reduced river flow as a result of drought."

eldavojohn writes "MIT's Microsystems Technology Laboratories is focusing on the manufacturing of chips as the variables that affect chip quality become more and more influential. From one of the researchers, "The extremely high speeds of these circuits make them very sensitive to both device and interconnect parameters. The circuit may still work, but with the nanometer-scale deviations in geometry, capacitance or other material properties of the interconnect, these carefully tuned circuits don't operate together at the speed they're supposed to achieve.""

An anonymous reader writes "It has been all over the news today: AMD announced the first of its Extensions for Software Parallelism, a series of x86 extensions to make parallel programming easier. The first are the so-called 'lightweight profiling extensions.' They would give software access to information about cache misses and retired instructions so data structures can be optimized for better performance. The specification is here (PDF). These extensions have a much wider applicability than just parallel programming — they could be used to accelerate Java, .Net, and dynamic optimizers." AMD gave no timeframe for when these proposed extensions would show up in silicon.

An anonymous reader clues us to research at Japan's National Institute of Advanced Industrial Science and Technology that has produced the ability to make animations by creating small plasma balls in mid-air. The technology doesn't use vapor or strange gases, just lasers to heat up oxygen and nitrogen molecules above the device: up to 1,000 brilliant dots per second, which makes smooth motion possible. When the tech improves it could be used for street signs or advertising.

mysqlbytes writes "According to a recent post on the BBC's website, Nokia has admitted to a problem in the BL-5C batteries made by Matsushita between December 2005 and November 2006. For some of us, it means longer battery life with a new lease of life and for some of us, no more burnt legs. You can check out the product advisory here."

BillOfThePecosKind writes "Researchers have demonstrated a new technology using tiny "ionic wind engines" that might dramatically improve computer chip cooling, possibly addressing a looming threat to future advances in computers and electronics. Purdue researchers funded by Intel have improved the "heat-transfer coefficient" by some 250%. I never liked water cooled systems, and this sounds promising. However I wonder how much ozone one of these things produces."

An anonymous reader writes "ECN magazine has posted a long interview with the Woz on his new passion: energy-efficient housing. 'ECN: In PC World, you said, "It's like the way I used to make computers" -- how so? Woz: Simple design. Think about the right way to build something and take a lot of time to get it the best that can be done with the fewest resources used. No waste. Build it right and with few parts it does a lot. Don't cover things with more and more and more technology for features. Design them in from the start. It starts with the architect, of a home or a computer, working from a knowledge of the building materials and a desire to choose wisely.'"

narramissic writes "Late last month a wireless prototype submitted by Microsoft and other members of the White Spaces Coalition was rejected by the FCC because it interfered with cable channels. Microsoft, though, claims that the device was malfunctioning when the FCC tested it. From the article: 'In a letter to the FCC Monday, Microsoft said the scanner in one of two prototypes was damaged and "operated at a severely degraded level. The damaged scanner accounted for the entire discrepancy between the Microsoft and the FCC bench test data," said Ed Thomas, a consultant for the White Spaces Coalition and a former chief of the FCC's Office of Engineering and Technology.'"

Flask_Man writes "Technology Review has an article about a small biotech company in the Silicon Valley that has successfully produced renewable gasoline from genetically modified bacteria, including the nefarious E.Coli bacteria. A pilot plant is slated to be constructed in California in 2008, and it is claimed that hundreds of different hydrocarbon molecules are capable of being produced. The modified bacteria make and excrete hydrocarbon molecules that are the length and molecular structure the company desires. From the article: 'To do this, the company is employing tools from the field of synthetic biology to modify the genetic pathways that bacteria, plants, and animals use to make fatty acids, one of the main ways that organisms store energy. Fatty acids are chains of carbon and hydrogen atoms strung together in a particular arrangement, with a carboxylic acid group made of carbon, hydrogen, and oxygen attached at one end. Take away the acid, and you're left with a hydrocarbon that can be made into fuel.'" We discussed something similar to this earlier this year.
