Multiple news agencies are reporting that the Pentagon has demanded the return of WikiLeaks' collection of secret documents relating to the war in Afghanistan. Defense Department spokesman Geoff Morrell said, "The only acceptable course is for WikiLeaks to take steps immediately to return all versions of all of these documents to the US government and permanently delete them from its website, computers and records." According to the BBC, Morrell also "acknowledged the already-leaked documents' viral spread across the internet made it unlikely they could ever be quashed," but hopes to prevent the dissemination of a further 15,000 documents WikiLeaks is reportedly in the process of redacting. "We're looking to have a conversation about how to get these perilous documents off the website as soon as possible, return them to their rightful owners and expunge them from their records." WikiLeaks, predictably, shows no sign of cooperating.

FleaPlus writes "At the recent Joint Propulsion Conference, SpaceX's rocket development facility director Tom Markusic unveiled conceptual plans for how its current Falcon 1 and Falcon 9 commercial rockets can be evolved into heavy-lift rockets, ranging from a Falcon X capable of lifting 38,000kg to orbit, up to a 140,000kg Falcon XX (more than either the Saturn V or the 75,000kg shuttle-derived rocket Congress currently plans on having NASA spend >$13B building). SpaceX presentations also discuss a new Merlin 2 heavy-lift engine, solar-electric cargo tugs, adapting their current engines for descent/ascent vehicles fueled by Mars-derived methane, and a desire for the government to take the lead on in-space nuclear thermal propulsion while commercial focuses on launchers. In a recent interview, SpaceX CEO/CTO Elon Musk expressed his goal of lowering the price of Mars transportation enough to enable early colonization in 20 years, and his own plans for retiring to Mars."

The FBI said this arrest and the arrests of three alleged operators in February were the result of a two-year joint investigation into the Mariposa Botnet, which may have infected as many as eight million to 12 million computers around the world."

bonhomme_de_neige writes "China renewed Google's internet license after it pledged to obey censorship laws and stop automatically switching mainland users to its unfiltered Hong Kong site, an official said. Google promised to 'obey Chinese law' and avoid linking to material deemed a threat to national security or social stability, said Zhang Feng, director of the Ministry of Industry and Information Technology's Telecoms Development Department, at a news conference." Update: 07/21 21:56 GMT by S : Changed headline to reflect that this is mainly just China trying to paint a better picture of the outcome. In a comment on the linked article, a Google representative said, "This piece suggests that Google has 'bowed' to censorship. That is not correct. We have been very clear about our committment [sic] to not censor our products for users in China. The products we have kept on Google.cn (Music, Translate, Product Search) do not require any censorship by Google. Other products, like web search, we are offering from Google.com.hk, and without censorship." If you go to google.cn, you can see the prominent link to the Hong Kong version of the site.

An anonymous reader writes "To study how aggression, fighting, and winning change the brain, scientists set up a tournament of mice fights. They watched as the lab rodents took a break from their hum-drum existence and battled it out (however, the researchers broke the first rule of Fight Club by publishing a paper about their findings [abstract]). They found clear evidence of the 'winner effect,' in which a mouse that has just won a fight maintains elevated levels of testosterone and aggression, and is therefore more likely to win the next bout. Interestingly, the winner effect was strongest in mice that were fighting in their own cages — i.e., those that had home-field advantage."

mattaw writes "In my blog post I describe a system designed to test a route to the potential future of computing. What do we do when we have computers with 1 million cores? What about a billion? How about 100 billion? None of our current programming models or computer architecture models apply to machines of this complexity (and with their corresponding component failure rate and other scaling issues). The current model of coherent memory/identical time/everything can route to everywhere; it just can't scale to machines of this size. So the scientists at the University of Manchester (including Steve Furber, one of the ARM founders) and the University of Southampton turned to the brain for a new model. Our brains just don't work like any computers we currently make. Our brains have a lot more than 1 million processing elements (more like the 100 billion), all of which don't have any precise idea of time (vague ordering of events maybe) nor a shared memory; and not everything routes to everything else. But anyone who argues the brain isn't a pretty spiffy processing system ends up looking pretty silly. In effect, modern computing bears as much relation to biological computing as the ordered world of sudoku does to the statistical chaos of quantum mechanics.

coondoggie writes "Not known for taking the demure route, researchers at DARPA this week announced a program aimed at building computers that exceed current peta-scale computers to achieve the mind-altering speed of one quintillion (1,000,000,000,000,000,000) calculations per second. Dubbed extreme scale computing, such machines are needed, DARPA says, to 'meet the relentlessly increasing demands for greater performance, higher energy efficiency, ease of programmability, system dependability, and security.'"

snydeq writes "US regulators are planning to investigate whether Apple is shutting out third parties such as Google and Microsoft in advertising on the iPhone and iPad under revised terms to its iAd mobile ad platform. Apple's revised developer terms prohibit ad analytics collection unless it is provided to an independent ad service provider whose primary business is serving mobile ads. If enforced, the proposed terms would prohibit developers from using Google's AdMob service on the iPhone, according to AdMob founder Omar Hamoui. Developers using AdMob to deliver ads on cross-platform mobile apps would have to go through an alternative service for the version of the app running on an Apple platform, according to the terms. It's an impractical solution that some are calling restrictive."

grrlscientist writes "A recently published study, intended to provide data to commercial fisheries in the Gulf of Mexico so they maximize their catch of Yellowfin Tuna, Thunnus albacares, whilst avoiding bycatch of critically endangered Atlantic (Northern) Bluefin Tuna, Thunnus thynnus, suggests that the Deepwater Horizon oil leak may devastate the endangered Atlantic bluefin population, causing it to completely collapse or possibly go extinct."

A team of scientists at the University of California San Diego, led by nano-engineering professor Joseph Wang, has designed some high-tech underwear that may save lives. Sensors in the waistband can monitor a person's blood pressure, heart rate, and other vital signs. The designers also hope that one day the underwear can release drugs to relieve pain and treat wounds. From the article: "But the technology's range of application goes beyond the military. 'We envision all the trend of personalized medicine for remote monitoring of the elderly at home, monitoring a wide range of biomedical markers, like cardiac markers, alerting for any potential stroke, diabetic changes, and other changes related to other biomedical scenario,' said Wang. Wearable biosensors can also provide valuable information to athletes or even measure blood alcohol levels."
