An anonymous reader writes "Researchers have discovered a promising method to regrow damaged nerves in adults. Brain and spinal-cord injuries typically leave people with permanent impairment because the injured nerve fibers (axons) cannot regrow. A study from Harvard and Carleton University, published in the December 10 issue of the journal Neuron, shows that axons can regenerate vigorously in a mouse model when a gene that suppresses natural growth factors is deleted. Here is the journal article (subscription required to view more than the abstract)."

dnaumov writes "FreeNAS, a popular, free NAS solution, is moving away from using FreeBSD as its underlying core OS and switching to Debian Linux. Version 0.8 of FreeNAS as well as all further releases are going to be based on Linux, while the FreeBSD-based 0.7 branch of FreeNAS is going into maintenance-only mode, according to main developer Volker Theile. A discussion about the switch, including comments from the developers, can be found on the FreeNAS SourceForge discussion forum. Some users applaud the change, which promises improved hardware compatibility, while others voice concerns regarding the future of their existing setups and lack of ZFS support in Linux."

protosage writes to tell us that Microsoft Interoperability is working towards opening up Outlook's .pst format under their Open Specification Promise. This should "allow anyone to implement the .pst file format on any platform and in any tool, without concerns about patents, and without the need to contact Microsoft in any way." "In order to facilitate interoperability and enable customers and vendors to access the data in .pst files on a variety of platforms, we will be releasing documentation for the .pst file format. This will allow developers to read, create, and interoperate with the data in .pst files in server and client scenarios using the programming language and platform of their choice. The technical documentation will detail how the data is stored, along with guidance for accessing that data from other software applications. It also will highlight the structure of the .pst file, provide details like how to navigate the folder hierarchy, and explain how to access the individual data objects and properties."

Foot-in-Mouth writes "Physorg has an article about a researcher, Dr. Simon Scarle at the University of Warwick's WMG Digital Laboratory, who needed to model some cardiological processes. Conventionally, he would requisition time on a university parallel-processing computer or use a network of PCs. However, Dr. Scarle's work history included gaming industry experience as a software engineer at a company associated with Microsoft Games Studio. His idea was that researchers could use Xbox 360s as an inexpensive parallel computing platform due to the console's hefty parallel processing-enabled GPU. He said, 'Although major reworking of any previous code framework is required, the Xbox 360 is a very easy platform to develop for and this cost can easily be outweighed by the benefits in gained computational power and speed, as well as the relative ease of visualization of the system.'"

A Blizzard representative today announced that they're working on a service for players to switch factions in World of Warcraft, going from Horde to Alliance or vice versa. "There's still much work to do and many details to iron out, but the basic idea is that players will be able to use the service to transform an existing character into a roughly equivalent character of the opposing faction on the same realm. Players who ended up creating and leveling up characters on the opposite factions from their friends have been asking for this type of functionality for some time, and we're pleased to be getting closer to being able to deliver it." They also said there would be "some rules involved with when and how the service can be used."

Hugh Pickens writes "New Scientist reports that instead of identifying chemicals that could point to life, NASA's robot explorers may have been toasting them by mistake. Even if Mars never had life, comets and asteroids that have struck the planet should have scattered at least some organic molecules over its surface but landers have failed to detect even minute quantities of organic compounds. Now scientists say they may have stumbled on something in the Martian soil that may have, in effect, been hiding the organics: a class of chemicals called perchlorates. At low temperatures, perchlorates are relatively harmless but when heated to hundreds of degrees Celsius perchlorates release a lot of oxygen, which tends to cause any nearby combustible material to burn. The Phoenix and Viking landers looked for organic molecules by heating soil samples to similarly high temperatures to evaporate them and analyse them in gas form. When Douglas Ming of NASA's Johnson Space Center in Houston, Texas, and colleagues tried heating organics and perchlorates like this on Earth, the resulting combustion left no trace of organics behind. "We haven't looked the right way," says Chris McKay of NASA's Ames Research Center. Jeffrey Bada of the University of California, San Diego, agrees that a new approach is needed. He is leading work on a new instrument called Urey which will be able to detect organic material at concentrations as low as a few parts per trillion. The good news is that, although Urey heats its samples, it does so in water, so the organics cannot burn up."

Nerdposeur points out that Cory Doctorow has a compelling piece in The Guardian today, arguing that network neutrality is not only crucial for the future of the Internet, but is what the ISPs owe to the public. He asks, "Does anybody else feel like waving a flag after reading this?" "If the phone companies had to negotiate for every pole, every sewer, every punch-down, every junction box, every road they get to tear up, they'd go broke. All the money in the world couldn't pay for the access they get for free every day... If they don't like it, let them get into another line of work — give them 60 days to get their wires out of our dirt and then sell the franchise to provide network services to a competitor who will promise to give us a solid digital future in exchange for our generosity."
