Hugh Pickens writes "New Scientist reports that, faced with global warming and potential oil shortages, the US Navy is experimenting with making jet fuel from seawater by processing seawater into unsaturated short-chain hydrocarbons that with further refining could be made into kerosene-based jet fuel. The process involves extracting carbon dioxide dissolved in the water and combining it with hydrogen — obtained by splitting water molecules using electricity — to make a hydrocarbon fuel, a variant of a chemical reaction called the Fischer-Tropsch process, which is used commercially to produce a gasoline-like hydrocarbon fuel from syngas, a mixture of carbon monoxide and hydrogen often derived from coal. The Navy team have been experimenting to find out how to steer the CO2-producing process away from producing unwanted methane by finding a different catalyst than the usual one based on cobalt. 'The idea of using CO2 as a carbon source is appealing,' says Philip Jessop, a chemist at Queen's University adding that to make a jet fuel that is properly 'green,' the energy-intensive electrolysis that produces the hydrogen will need to use a carbon-neutral energy source; and the complex multi-step process will always consume significantly more energy than the fuel it produces could yield. 'It's a lot more complicated than it at first looks.'"

chrb writes "BBC News is reporting on how the Alive in Afghanistan project is helping to oversee the Afghan elections using open-source technologies. The site was set up by Brian Conley, who is also responsible for 'Alive in Baghdad', 'Alive in Mexico', and who was arrested for filming protests in China last year. The Afghan site uses FrontlineSMS and Ushahidi to process and visualize SMS texts from Afghani citizens, allowing reports from all over the country to be rapidly collated and re-distributed globally."

Joshua writes "Researchers from Japan have calculated Pi to over 2.5 trillion decimals using the T2K Open Supercomputer (which is currently ranked 47th in the world according to a June, 2009 report from Top500.org). This new number more than doubles the previous record of about 1.2 trillion decimals set in 2002 by another Japanese research team. Unfortunately, there still seems to be no pattern."

coondoggie writes "The US Marine Corps has a request — build and rapidly deploy more 10lb-or-under robots its personnel can throw into dangerous situations that can quickly gather information without endangering Marines. The throwable robot is part of a family of robots that would range from the 10lb version to one that would act as a central controlling device and weigh close to 300lbs. Marine commanders are demanding ever lighter robots so that troops don't have to offload critical equipment from their rucksacks to accommodate them."

Several sites are reporting on the addition of extra fees to PayPal that are just starting to become common knowledge. While PayPal has certainly had their fair share of controversy, the new "transaction fees" that promise to affect the entire customer base are already well on their way to becoming another. "For example, a personal account sending another personal account money for a one-time payment for, say, mowing your lawn was not previously charged any fees on either side, but is now charged the usual transaction fee (the sender gets to decide who pays). The only way to avoid this is by selecting 'gift' when making the transfer — something you can't do if you're following through on a purchase or invoice from someone. And, if you fall into this category (which many people do), it's likely that you had no idea about the changes until just now."

pdragon04 writes "Researchers at the Ecole Polytechnique Fédérale de Lausanne in Switzerland have found that robots equipped with artificial neural networks and programmed to find 'food' eventually learned to conceal their visual signals from other robots to keep the food for themselves. The results are detailed in a PNAS study published today."

An anonymous reader writes "An interesting article yesterday about the unmasking of the recent creator of the controversial and iconic Obama/Joker image that has been popping up around Los Angeles with the word Socialism under it. The Los Angeles Times has identified the images' creator as Firas Alkhateeb. Even more interesting though is the fact that after getting over 20,000 hits on the image at Flickr, Flickr removed the image from Alkateeb's photostream, citing 'copyright' concerns. The image in question is clearly both an independent derivative work and unquestionably a parody of the President and Time Magazine which would be covered under fair use. It has appeared on many other sites without issue on the Internet." According to the same reader, "Flickr also recently nuked a user's entire photostream over negative comments on President Obama's official photostream."

Flea of Pain writes "Fable III is finally in the works! 'Peter Molyneux revealed that his team is working on Fable III, which will arrive in late 2010, two years after the release of Fable II. The game will give you the primary task of becoming Albion's king and leading the people to happiness and the kingdom to glory. Fable III will be something bold and different, Molyneux promises, stating that story and drama will play a major part in it. New things will be done with the dog and the bread-crumb-trails mechanic, which were present in the second game, and you will be offered complete control of your actions and your people's actions, as you will be the king of Albion. ... [Y]ou will need to balance many things, including poverty and greed, tyranny and compassion or progress and tradition, all in order to keep your subjects happy. Furthermore, you will be able to set taxes and decide how you will rule your subjects. Your spouse, be it a king or a queen, will also point you into various directions over the course of the game. It seems that you will start as a son or daughter of the hero from Fable II and then progress until the halfway point of the game when you will be named king or queen of Albion. This means that you need to keep your save data from Fable II in order for a higher degree of customization.'"

Death Metal writes "The phone network is thus not just a technical infrastructure, but a socioeconomic one. The more Americans abandon it to go mobile-only or make phone calls over the Internet, the more fragile it becomes: its high fixed costs have to be spread over ever fewer subscribers. If the telephone network in New York State were a stand-alone business, it would already be in bankruptcy. In recent years it has lost 40% of its landlines and revenues have dropped by more than 30%."

NSN A392-99-964-5927 writes "My handwriting abilities have deteriorated over the years. Putting a real pen to paper, I get frustrated over how to spell correctly, as I am so accustomed to using a keyboard and knowing where the letters are. Having spoken to a few friends, I've found that this has become apparent to them, too. I've noticed that my grammar is also affected; maybe this is because I spent too much time on IRC and lowered my standards. Hand-written words are now becoming obsolete. There is often no need to think about writing anymore, or about how something is spelled. Are other Slashdotters having the same problem? (I'm used to Telex machines, which should give you an indication of how old I am.)"

Hork_Monkey writes "CCP Games, developer of the popular MMO EVE Online, has announced a new game called Dust 514. Building on the EVE universe, this game will provide planetary combat from an RTS and FPS perspective, with significant impact into the space combat aspects of EVE Online. Love or hate EVE Online, this appears to be an innovative way to expand the overall universe by catering to a different gamer audience. A video with a trailer and further explanation was posted from GDC Europe."

Death Metal sends along this excerpt from Torrentfreak about how Global Gaming Factory, the company who is buying The Pirate Bay, plans to change the site in order to avoid the wrath of the entertainment industry: "In a letter addressed to [shareholders], the company confirms that the new Pirate Bay will become a pay site, while revealing some additional details on how GGF plans to legalize it. To please the entertainment industry, GGF will install a system that will allow the copyright holders to either authorize the 'illegal' torrent or have it removed from the site. If the copyright holder chooses the first option, they will be compensated every time the file is downloaded. In addition, the board says that it will pay penalties if it has to. 'The holder will be able to leave the file and obtain compensation or ask for removal of the file. GGF will also pay any penalties that may arise,' the GGF board announced."

KentuckyFC writes "Last year, physicists calculated that a solar sail about a kilometer across with a mass of 300 kg (including 150 kg of payload) would have a peak acceleration of roughly 0.6g if released about 0.1AU from the Sun, where the radiation pressure is highest. That kind of acceleration could take it to the heliopause — the boundary between the Solar System and interstellar space — in only 2.5 years; a distance of 200 AU. In 30 years, it could travel 2500AU, far enough to explore the Oort Cloud. But the team has discovered a problem. Ordinary Newtonian physics just doesn't cut it for the kind of navigational calculations needed for this journey. Because the sail has to be released so close to the Sun, it becomes subject to the effects of general relativity. And although the errors these introduce are small, they become magnified over the course of a long journey, sending the sail roughly 1 million kilometers off course by the time it reaches the Oort Cloud. What these guys are saying is that if ever such a sail is launched (and the earliest estimate is 2040), the navigators will have to be proficient in a new discipline of relativistic navigation."

kamapuaa writes "According to a study published in the upcoming October issue of the American Journal of Preventive Medicine, the average US video game player is 35 years old, overweight, and tends toward depression. Specifically, female video game players tended towards depression, while males tended towards large BMIs. While the study itself points to several conclusions, one researcher noted: '... habitual use of video games as a coping response may provide a genesis for obsessive-compulsive video-game playing, if not video-game addiction.'" On the flip side, the Washington Post is running a story about the mental health benefits of playing video games.

Several readers have written to tell us of a ruling in the New York Supreme Court which will allow model Liskula Cohen to find out the identity of an anonymous blogger who posted some of her photos with captions including the words "psychotic," "skank," and "ho." The site was part of Blogger.com, and Google has already complied with a request for the author's IP address and email. "[Cohen's attorney] said that once his legal team tracks the e-mail address to a name, the next step will be to sue Cohen's detractor for defamation. He said he suspected the creator of the blog is an acquaintance of Cohen. The blog has not been operational for months. The unidentified creator of the blog was represented in court by an attorney, Anne Salisbury, who said her client voluntarily took the blog down when Cohen initiated legal action against it. ... the judge quoted a Virginia court that ruled in a similar case that nameless online taunters should be held accountable when their derision crosses a line. 'The protection of the right to communicate anonymously must be balanced against the need to assure that those persons who choose to abuse the opportunities presented by this medium can be made to answer for such transgressions.'"
