kpearson writes "Distributed.net's 8-year-old OGR-25 distributed computing project has just proven conclusively that the predicted shortest 25-mark Golomb ruler is optimal. 'The total length of the ruler is 480, with marks at positions: 0 12 29 39 72 91 146 157 160 161 166 191 207 214 258 290 316 354 372 394 396 431 459 467 480. (This ruler may alternatively be expressed in terms of the distance between those positions, which is how dnetc displays them: 12-17-10-33-19-...).' 124,387 people participated in the project and two people found the shortest ruler, one on October 10, 2007 and the other on March 24, 2008."

Wired reports on the Enriched Xenon Observatory 200, a particle detector scientists hope will answer the question of why there is significantly more matter than antimatter in the universe. Quoting: "The new detector will try to fill in the picture, determining basic features of [neutrinos], like their mass and whether or not they, unlike almost all other particles, are their own antiparticles. That quirk is why some scientists believe neutrinos could be the mechanism for the creation of our matter-filled universe. Almost all other particles have an antiparticle twin that, if it comes into contact with the particle, immediately annihilates it. But if neutrinos are their own antiparticles they could conceivably be knocked onto matter's 'team,' thereby causing the cascading win for matter over antimatter that we know occurred. As the Indian theoretical physicist G. Rajasekaran put it in a speech [PDF] earlier this year, neutrinos that are their own antiparticles would explain 'how, after [the] annihilation of most of the particles with antiparticles, a finite but small residue of particles was left to make up the present Universe.'"

ElementC writes "Sometime yesterday Nintendo uploaded the latest Wii system update. This update quietly patches a few bugs that allowed the installation of both homebrew and warez apps. Currently installed apps such as the Homebrew Channel and the video DVD library, DVDX, are reportedly not affected. Those not installing this update are blocked out of the Wii Shop channel and in the future may be blocked out of certain games. Team Twiizers cracked the last update within about eight hours. They're already on the case. Readers familiar with the architecture of the Wii will find the list of currently discovered changes interesting."

An anonymous reader writes "Researchers at the University of Washington have found that RFID tags used in two new types of border-crossing documents in the US are vulnerable to snooping and copying. The information in these tags could be copied on to another, off-the-shelf tag, which might be used to impersonate the legitimate holder of the card." You can also read the summary of the researchers' report.

An anonymous reader writes "NerdKits has an example of their latest project, an iPhone-controlled R/C car running around Boston and MIT. Technical details, build-it-yourself instructions, and a video of the car in action are all included."

r2k writes "While the Apple rumours posted yesterday highlight some of the most commonly talked-about opinions, a writer for CNet UK sat down with Mahalo's Jason Calacanis, who told CNet he knew for a fact that Apple is developing fully networked LCD TV sets. As the writer points out, Apple dropped 'Computer' from its company name for a very good reason."

Adam Williamson writes "Mandriva has today released Mandriva Linux 2009, the new major release of the popular distribution. 2009 is a bold release which brings the new KDE 4 as the default desktop, along with a re-designed installer and Mandriva Control Center and many other new features. Other significant updates include GNOME 2.24, OpenOffice.org 3, Mozilla Firefox 3, and kernel 2.6.27. Key features include new graphical in-line upgrade capability, netbook compatibility, class-leading hardware support, and further improved support for working with mobile devices. For more details, see the Release Tour and the Release Notes. Get it at the download page, or go straight to the torrent list."

An anonymous reader writes with this snippet from Gizmodo: "NASA's Messenger (MErcury Surface, Space ENvironment, GEochemistry and Ranging spacecraft) has flown by just 125 miles over the surface of Mercury, the closest planet to the Sun and the smallest in the Solar System. This is the first time in history that the whole planet is going to be photographed in its entirety by an Earthling probe, with amazing resolution and ultra-crisp detail." The picture at the top of the linked story is fantastic, too.

musther writes "An Australian airline Qantas Airbus A330-300, suffered 'a sudden change of altitude' on Tuesday. "The mid-air incident resulted in injuries to 74 people, with 51 of them treated by three hospitals in Perth for fractures, lacerations and suspected spinal injuries when the flight bound from Singapore to Perth had a dramatic drop in altitude that hurled passengers around the cabin." Now it seems Qantas is seeking to blame interference from passenger electronics, and it's not the first time; 'In July, a passenger clicking on a wireless mouse mid-flight was blamed for causing a Qantas jet to be thrown off course.' Is there any precedent for wireless electronics interfering with aircraft systems? Interfering with navigation instruments is one thing, but causing changes in the 'elevator control system' — I would be quite worried if I thought the aircraft could be flown with a bluetooth mouse."

An anonymous reader writes "A team of US researchers has asked the following question in the new field of systems biology: 'Do we understand how a cell produces electricity well enough to design one, and to optimize that design?' They believe it should be possible to build artificial cells replicating the electrical behavior of electric eel cells. In fact, such artificial cells could deliver better performance — as much as 40% more energy than real eel cells, a computer model suggests. They could be used to power medical implants and other small devices."

Many readers reminded us of what no-one can have failed to hear: that the Congress passed and the President signed a $700B bailout bill in an attempt to avert the meltdown of the US economy. The bill allocates $700 billion to the Treasury Department for the purchase of so-called "toxic assets" that have been weighing down Wall Street balance sheets. This isn't particularly a tech story, though tech will be affected as will virtually all parts of the economy, and not just in the US. Among the $110B in so-called pork added to the bill to sway reluctant legislators are extensions of popular tax benefits for business R&D and alternative energy, relief for the growing pool of people subject to the alternative minimum tax, and a provision raising the FDIC's ceiling of guaranteed deposits to $250,000. Some limits were also imposed on executive compensation, though it's unclear whether they will be effective.

An anonymous reader writes with news that ArtistDirect, the company who acquired MediaDefender, has launched another company called PiCast for the purpose of P2P video distribution. The reader says: "This is a strange twist for a company which last year set up a video-sharing site called Miivi in an attempt to entrap users uploading copyrighted content, and was caught launching a DoS attack against Revision3, which we discussed earlier this year."

An Anonymous reader writes "CNN is reporting 'A weathered sweat shirt, cash and a pilot license with Fossett's name were found Tuesday near Mammoth Lakes, police Chief Randy Schienle said.' The license did not have a photo. '"We're not certain that it belongs to Steve Fossett, but it certainly has his name on the ID," Schienle said.'"

Eurogamer reports on some good news for fans of the Final Fantasy series: a new game is in development for the Nintendo Wii and DS systems. "It's said to be titled Final Fantasy Crystal Chronicles: Echoes of Time. ... the game will apparently be playable on both machines at once, thanks to the spiffing new Pollux engine. So, while whoever is the best negotiator/fighter/Wii owner is playing on the big screen, another lucky adventurer can wade in on the DS, presumably following around and summoning Ifrit on their elder siblings. This harks back to the series' origins on DS, with the first CC game enjoying the relative splendour of Gamecube/GBA link-up play."

Valve made a brief announcement on Friday that they will be allowing the download of user-created game mods directly from Steam. "Once installed, these MODs will appear in your 'My Games' list and will receive automatic updates just like other games on Steam. Also, these MODs now take advantage of Steamworks, which provides stat tracking and tighter integration with the Steam community." Mods will be available for five different games to start, and more in the future.
