Lanxon writes "A team of researchers at the Royal Veterinary College in London has built a 'cyber-cockroach' (a cockroach wearing an accelerometer in a tiny backpack) to try and better understand the movements of many-legged animals. They found that unlike bipedal creatures, animals with more than two legs don't adjust their movements when walking over a softer surface." The academic paper is available from the Journal of Experimental Biology. This research will be helpful in finding better ways for multi-legged robots to navigate difficult terrain.

An anonymous reader writes "The EXT family of file systems (ext2, ext3, ext4) have ruled many Linux distributions for a long time, and Ubuntu has been no exception. But things may no longer be the same for Ubuntu 10.10 Maverick Meerkat. Canonical's Scott James Remnant said in a blog post that plans are on for doing work to have btrfs as an installation option, and that the possibility of making it the default file system in Ubuntu 10.10 has not been ruled out."

GMGruman writes "Nokia, Apple, and HTC are all suing each other over mobile patents. Google and Microsoft are also in the game. InfoWorld's Paul Krill explains what the fight is all about: control over multitouch, the technology that enables gesture interfaces on iPads, iPhones, and other smartphones. And he explains the chances that the companies will settle their dispute as they jockey for advantage, why Apple has been playing hardball, and why competitors are fighting back just as hard."

Plocmstart writes "Here's what EETimes.com is claiming to be the first teardown of the A4 processor. 'Apple's iPad chip is a single-core ARM A8 made by Samsung. Through various benchmarking testing, UBM TechInsights was able to find out the details of the A4 processor.'"

An anonymous reader writes "Here's a listing of several scientific and economic guides for estimating the volume of flow of the leak in the Gulf of Mexico erupting at a rate of somewhere around 1 million barrels per day. A new video released shows the largest hole spewing oil and natural gas from an aperture 5 feet in diameter at a rate of approximately 4 barrels per second. The oil coming up through 5,000 feet of pressurized salt water acts like a fractionating column. What you see on the surface is just around 20% of what is actually underneath the approximate 9,000 square miles of slick on the surface. The natural gas doesn't bubble to the top but gets suspended in the water, depleting the oxygen from the water. BP would not have been celebrating with execs on the rig just prior to the explosion if it had not been capable producing at least 500,000 barrels per day — under control. If the rock gave way due to the out-of-control gushing (or due to a nuke being detonated to contain the leak), it could become a Yellowstone Caldera type event, except from below a mile of sea, with a 1/4-mile opening, with up to 150,000 psi of oil and natural gas behind it, from a reserve nearly as large as the Gulf of Mexico containing trillions of barrels of oil. That would be an Earth extinction event."

kkleiner writes "Stanford's Junior, the robot car that took second place at DARPA's Grand Challenge in 2007, has learned how to perform a tire-squealing 180-degree spin into a skin-tight parking space. Similar to a James Bond action scene, the maneuver is impressive and would be extremely difficult for a human to pull off. We won't be handing the keys over to robot cars anytime soon, but Stanford shows us that at least for some driving tasks robot cars can already meet or even exceed human ability."

separsons writes "Researchers at Duke University recently used DNA to craft tiny chips used in computers and electronic circuits. By mixing DNA snippets with other molecules and exposing them to light, researchers created self-assembling, DNA-based logic circuits. Once perfected the tech could serve as an endlessly abundant, cheap alternative to silicon semiconductors. Chris Dwyer, lead researcher on the project, says that one grad student using DNA to make self-assembling circuits could produce more logic circuits in one day than the global silicon chip industry can create in an entire month!"

aftertaf writes "North Korea claims to have achieved nuclear fusion by building what it describes as a 'unique thermo-nuclear reaction device.' This announcement was met by skepticism on just about every news website this side of Saturn. Pyongyang claims its latest scientific breakthrough coincides with the birthday of the country's founder and eternal president Kim Il-sung. This is not the first time it seems that the laws of nature have been bent in his honor. According to official biographies, when his son, Kim Jong-il, was born, a new star appeared in the sky." No doubt the Dear Leader combined the atomic nuclei by hand.

destinyland writes "MIT researchers have developed a method of splitting a water molecule by emulating the way blue-green algae separates oxygen from hydrogen. One chemistry professor called it 'an extremely clever piece of work' that addresses 'the nanoscale organization of the components.' Using sunlight rather than electricity to make hydrogen from water could greatly improve the efficiency of the process. The hydrogen can be stored for generating electricity or burned as fuel for cars. The project is being led by the winner of a 2004 MacArthur Foundation genius grant, who uses genetically engineered viruses as templates for nanoscale electronic components. 'Suddenly, I wondered, what if we could assemble materials like the abalone does — but not be limited to one element?'" Here is the press release from MIT; the research paper is available only to subscribers of Nature Nanotechnology (or those willing to part with $18).

An anonymous reader writes "The oil leak in the Gulf of Mexico could be stopped with an underground nuclear blast, a Russian newspaper reports. Komsomoloskaya Pravda, the best-selling Russian daily, reports that in Soviet times such leaks were plugged with controlled nuclear blasts underground. The idea is simple, KP writes: 'The underground explosion moves the rock, presses on it, and, in essence, squeezes the well's channel.' It's so simple, in fact, that the Soviet Union used this method five times to deal with petrocalamities, and it only didn't work once."

ElectricSteve writes "Metamaterials are man-made substances designed to do some very weird things that natural materials don't. The path of a beam of light through a natural material like glass is predictable, but scientists from the California Institute of Technology have engineered an optical material that bends light in the wrong direction. This new negative-index metamaterial (NIM) could have several valuable uses including invisibility cloaking, superlensing (imaging nano-scale objects using visible light), and improved light collection in solar cells."

kkleiner writes "Selling products whose design anyone can access, edit, or use on their own is pretty crazy. It's also good business. At the annual hacker conference Foo Camp East this year, Phillip Torrone and Limor Fried from Adafruit Industries gave a rapid fire five-minute presentation on thirteen companies with million+ dollar revenues from open source hardware. The thirteen add up to $50 million this year. While this business model is counter-intuitive for those accustomed to our current patent- and copyright-encrusted system, Torrone and Fried estimate that the industry will reach a billion dollars by 2015."

An anonymous reader writes "India, the world's largest democracy, votes entirely on government-made electronic voting machines that authorities claim are 'tamperproof,' 'infallible,' and 'perfect,' but last week security researchers proved that they can be manipulated to steal elections. A team led by Hari Prasad, Professor J. Alex Halderman, and Rop Gonggrijp released an awesome video that shows off hardware hacks they built. These machines are much simpler than e-voting designs used in the US, but as the research paper explains, this makes attacking the hardware even easier. Halderman's students at the University of Michigan took only about a week to build a replacement display board that lies about the vote totals, and the team also built a pocket-sized device that clips onto the memory chips, with the machine powered on, and rewrites the votes. Clippy says, 'It looks like you're trying to rig an election ...'"

1sockchuck writes "In the past year we've seen several new cooling systems that submerge rack-mount servers. Now liquid immersion cooling is coming to blade servers. Liquid-cooled PC specialist Hardcore Computer has entered the data center market with Liquid Blade, which features two Intel 5600 Xeon processors with an S5500HV server board in a chassis filled with dielectric fluid. Hardcore, which is marketing the product for render farms, says it eliminates the need for rack-level fans and room-level air conditioning. In recent months Iceotope and Green Revolution Cooling have each introduced liquid cooling for rack-mount servers."

alexhiggins732 writes with this tantalizing PopSci snippet: "A demo of a quantum calculation carried out by Japanese researchers has yielded some pretty mind-blowing results: a single molecule can perform a complex calculation thousands of times faster than a conventional computer. A proof-of-principle test run of a discrete Fourier transform — a common calculation using spectral analysis and data compression, among other things — performed with a single iodine molecule transpired very well, putting all the molecules in your PC to shame."

Nom du Keyboard writes "Sharp Aquos brand televisions are making a big deal about their Quattron technology of adding a 4th yellow pixel to their RGB sets. While you can read a glowing review of it here, the engineer in me is skeptical because of how all the source material for this set is produced in 3-color RGB. I also know how just making a picture brighter and saturating the colors a bit can make it more appealing to many viewers over a more accurate rendition – so much for side-by-side comparisons. And I laugh at how you are supposed to see the advantages of 4-color technology in ads on your 3-color sets at home as you watch their commercials. It sounds more like hype to extract a higher profit margin than the next great advance in home television. So is it real?"

An anonymous reader writes "Ever wonder what happened to PXE? Intel's popular standard for diskless booting hasn't been updated since 1999, and has missed out on such revolutions as wireless Ethernet, cloud computing, and iSCSI. An open source project called Etherboot has been trying to drag PXE into the 21st century. One of their programmers explains how to set up diskless booting for your cloud, using copy-on-write to save space."

bth writes with this excerpt of an AP story as carried by Yahoo: "Federal regulators are endorsing Hollywood's efforts to let cable and satellite TV companies turn off output connections on the back of set-top boxes to prevent illegal copying of movies. ... In its decision Friday, the agency stressed that its waiver includes several important conditions, including limits on how long studios can use the blocking technology. The FCC said the technology cannot be used on a particular movie once it is out on DVD or Blu-ray, or after 90 days from the time it is first used on that movie, whichever comes first."

An anonymous reader writes "Is vibration killing disk performance? ZDnet reports on research that a carbon fiber anti-vibration rack increased random read performance by 56% to 246% and random write [performance] by 34% to 88%. Vibration is a known disk problem, but this is one of the few attempts to quantify its impact — which looks to be much greater than suspected."
