An anonymous reader sends along Chris Soghoian's blog entry revealing that Sprint Nextel provided law enforcement agencies with its customers' GPS location information over 8 million times between September 2008 and October 2009. The data point comes from a closed industry conference that Soghoian attended, at which Paul Taylor, Electronic Surveillance Manager at Sprint Nextel, said: "[M]y major concern is the volume of requests. We have a lot of things that are automated but that's just scratching the surface. One of the things, like with our GPS tool. We turned it on the web interface for law enforcement about one year ago last month, and we just passed 8 million requests. So there is no way on earth my team could have handled 8 million requests from law enforcement, just for GPS alone. So the tool has just really caught on fire with law enforcement. They also love that it is extremely inexpensive to operate and easy, so, just the sheer volume of requests they anticipate us automating other features, and I just don't know how we'll handle the millions and millions of requests that are going to come in." Soghoian's post details the laws around disclosure of wiretap and other interception data — one of which the Department of Justice has been violating since 2004 — and calls for more disclosure of the levels of all forms of surveillance.

itwbennett writes "A new data center being built in Helsinki, scheduled to go live at the end of January, will generate energy and deliver hot water for the city. The data center is located in an old bomb shelter and is connected to the Helsinki public energy company's district heating system, which works by pumping boiling water through a system of pipes to households in Helsinki. The recycled heat from the data center could add about 1 percent to the total energy generated by the energy company's system in the summer." The article doesn't say what the overall efficiency of the heat recovery is. Researchers at MIT are working on a new energy-conversion technology based on quantum dots that they say has already demonstrated 40% of the Carnot efficiency limit — 4 times what is achieved by current commercial thermoelectric devices. The researchers believe they can reach 90% of the Carnot limit.

necro81 writes "The NY Times is reporting on a new study from Osram, a German lighting manufacturer, which has calculated the total lifecycle energy costs of three lightbulb technologies and found that both LEDs and CFLs use approximately 20% of the energy of incandescents over their lifetimes. While it is well known that the newer lighting technologies use a fraction of the energy of incandescents to produce the same amount of light, it has not been proven whether higher manufacturing energy costs kept the new lighting from offering a net gain. The study found that the manufacturing and distribution energy costs of all lightbulb technologies are only about 2% of their total lifetime energy cost — a tiny fraction of the energy used to produce light." The study uses the assumption that LEDs last 2.5 times longer than CFLs, and 25 times longer than incandescents.

Hugh Pickens writes "The Telegraph reports that scientists have created the first artificial meat by extracting cells from the muscle of a live pig and putting them in a broth of other animal products where the cells then multiplied to create muscle tissue. Described as soggy pork, researchers believe that it can be turned into something like steak if they can find a way to 'exercise' the muscle and while no one has yet tasted the artificial meat, researchers believe the breakthrough could lead to sausages and other processed products being made from laboratory meat in as little as five years' time. '"What we have at the moment is rather like wasted muscle tissue. We need to find ways of improving it by training it and stretching it, but we will get there," says Mark Post, professor of physiology at Eindhoven University. "You could take the meat from one animal and create the volume of meat previously provided by a million animals." Animal rights group Peta has welcomed the laboratory-grown meat, announcing that "as far as we're concerned, if meat is no longer a piece of a dead animal there's no ethical objection while the Vegetarian Society remained skeptical. "The big question is how could you guarantee you were eating artificial flesh rather than flesh from an animal that had been slaughtered. It would be very difficult to label and identify in a way that people would trust.""

Several readers noted the latest fallout from the Climate Research Unit's Climategate: the admission by the University of East Anglia that the raw data behind important climate research was discarded in the 1980s, "a time when climate change was seen as a less pressing issue" according to the Times (UK) article. The Telegraph quotes Phil Jones, beleagured head of the CRU: "Our global temperature series tallies with those of other, completely independent, groups of scientists working for NASA and the National Climate Data Centre in the United States, among others. Even if you were to ignore our findings, theirs show the same results. The facts speak for themselves; there is no need for anyone to manipulate them." Some of the data behind these other results can likely be found in a new resource that jamie located up at the Real Climate site: a compilation of links to a wide variety of raw data about climate. From the former link: "In the aftermath of the CRU email hack, many people have come to believe that scientists are unfairly restricting access to the raw data relating to the global rise in temperature. ... We have set up a page of data links to sources of temperature and other climate data, codes to process it, model outputs, model codes, reconstructions, paleo-records, the codes involved in reconstructions etc."

NASA officials will speak before members of Congress this week in an effort to gain support for more stringent launch safety considerations for the space shuttle's successor. Crew safety remains a major concern for lawmakers while they debate NASA's future and the potential integration of private companies into US space flight plans. "The demonstrated probability of a shuttle launch disaster is 1 in 129. NASA's 83 astronauts think those odds can be improved to 1 in 1,000. Independent safety experts agree. 'None of us want to repeat the accident history of the shuttle,' said retired Navy Vice Adm. Joseph Dyer, chairman of the Aerospace Safety Advisory Panel, a group organized to oversee NASA programs after three astronauts died in the 1967 Apollo 1 launch pad fire. ... NASA's Astronaut Office began a re-evaluation of next-generation launch vehicle safety after the loss of Columbia's crew. The guiding principles laid out in a May 2004 report remain current, astronauts said. Launching astronauts into low Earth orbit is dangerous. But an order-of-magnitude reduction of risk is achievable 'and should therefore represent a minimum safety benchmark for future systems,' the report says."

An anonymous reader sends in this link to a video of 12-1/2 minutes of Space Shuttle pr0n. The people at the Johnson Space Center put together this video of the ascent of STS-129 using multiple imagery assets — ground, air, booster, and the shuttle itself. The booster's-eye view of splashdown and immersion is something you don't see every day. As a bonus, another anonymous reader shared a beautiful photo of the shuttle flying over rugged terrain after it separated from the ISS last week.

University of Utah physicist Tim Garrett has published a study that approaches the economy and its relation to global warming as a physics problem — and comes to some controversial conclusions: that rising carbon dioxide emissions cannot be stabilized unless the world's economy collapses or society builds the equivalent of one new nuclear power plant each day. The study was panned by economists and was rejected by several journals before its acceptance in the journal Climatic Change. "[Garrett discovered that] Throughout history, a simple physical constant... links global energy use to the world's accumulated economic productivity, adjusted for inflation. So it isn't necessary to consider population growth and standard of living in predicting society's future energy consumption and resulting carbon dioxide emissions. ... 'I'm not an economist, and I am approaching the economy as a physics problem,' Garrett says. 'I end up with a global economic growth model different than they have.' Garrett treats civilization like a 'heat engine' that 'consumes energy and does "work" in the form of economic production, which then spurs it to consume more energy,' he says. That constant is 9.7 (plus or minus 0.3) milliwatts per inflation-adjusted 1990 dollar. So if you look at economic and energy production at any specific time in history, 'each inflation-adjusted 1990 dollar would be supported by 9.7 milliwatts of primary energy consumption,' Garrett says. ... Perhaps the most provocative implication of Garrett's theory is that conserving energy doesn't reduce energy use, but spurs economic growth and more energy use."

siddesu writes in with "compelling" new data that chemical and fossil evidence of ancient microbial life on Mars was carried to Earth in a Martian meteorite. The finding is being highlighted by the same NASA team who made the initial discovery 13 years ago. Spaceflight Now has more details of the analysis.

In the wake of the CRU "climategate" leak, reader Geoffrey.landis sends along a New York Times blog profile of Judith Curry, a climate scientist at Georgia Tech. "Curry — unlike many climate scientists — does not simply dismiss the arguments of 'climate skeptics,' but attempts to engage them in dialogue. She can, as well, be rather pointed in criticizing her colleagues, as in a post on the skeptic site climateaudit where she argues for greater transparency for climate data and calculations (mirrored here). In this post she makes a point that tribalism in science is the main culprit here —- that when scientists 'circle the wagons' to defend against what they perceive to be unfair (and unscientific) attacks, the result can be damaging to the actual science being defended. Is it still possible to conduct a dialogue, or is there no possible common ground?"

mdsolar writes "In the Dec. 7 edition of The Nation, Christian Parenti details what he considers to be the real problem with nuclear power as a solution to carbon emissions in the US: Not the high cost of new nuclear power, but rather the irresponsible relicensing of existing nuclear power plants by the Nuclear Regulatory Commission. The claim is that the relicensed plants — amounting to more than half ot the 104 original 1970s-era nukes in the US — operate like zombies beyond their design lifetimes only because of lax regulation spurred by concern over carbon dioxide emissions. But these plants are actually failing, as demonstrated by a rash of accidents. And some of the ancient plants are now being allowed to operate at 120% of their designed capacity. There is a video interview with Parenti up at Democracy Now."

ElectricSteve writes "Her Royal Highness Crown Princess Mette-Marit of Norway officially opened the world's first osmotic power plant prototype on November 24. The prototype has a limited production capacity and will be used primarily for testing and data validation, leading to the construction of a commercial power plant in a few years time. Statkraft claims that the technology has the global potential to generate clean, renewable energy equivalent to China's total electricity consumption in 2002 or half of the EU's total power production" What's osmotic power? Wikipedia to the rescue!

Last year we ran the story of Yves Rossy and his DIY jetwings. Yves spent $190,000 and countless hours building a set of jet-powered wings which he used to cross the English Channel. Rossy's next goal is to cross the Strait of Gibraltar, from Tangier in Morocco and Tarifa on the southwestern tip of Spain. From the article: "Using a four-cylinder jet pack and carbon fibre wings spanning over 8ft, he will jump out of a plane at 6,500 ft and cruise at 130 mph until he reaches the Spanish coast, when he will parachute to earth." Update 18:57 GMT: mytrip writes: "Yves Rossy took off from Tangiers but five minutes into an expected 15-minute flight he was obliged to ditch into the wind-swept waters."

westtxfun writes "The STEREO satellites recently confirmed the existence of solar mega-tsunamis when they captured height data after a sunspot recently erupted. The scale of this tsunami literally dwarfs the Earth's diameter — it was 62,000 miles high and raced across the surface at 560,000 mph! STEREO A and B orbit 90 degrees apart and luckily, one was overhead while the other saw the eruption on the limb. This gave NASA scientists enough data to confirm the tsunami wasn't a shadow, solving a modern solar mystery. The images are simply stunning, to boot."

Glyn Moody writes "The response to Google's Chromium OS has been rather lukewarm. But suppose it's just part of something much bigger: a netbook computer from Google that would cost absolutely nothing. Because all the apps and data are stored in the cloud, storage requirements would be minimal; screens are getting cheaper, and the emphasis on lean code means that a low-cost processor could be used. Those relatively small hardware costs could then be covered by advertising in the apps — after all, they are just Web pages. Interestingly, Google has not only rolled out advertising to more of its services recently, it has also started running AdSense ads in the desktop application Google Earth. Would you accept a free Google netbook — or is the price you would pay in terms of the company knowing even more about what you do on an hour-by-hour basis just too high?"

Audrey23 writes "I am traveling to London from Washington state for two weeks in December for pleasure (use-it-or-lose-it vacation scenario) and was wondering if I should bother bringing my laptop. I know that I would have to change the region code on my wireless amongst other things and the power cord would have to be changed for a UK outlet. Would I be better off not bringing my laptop and just using Internet kiosks (do they exist in London?) or would having my laptop be a better choice to keep in touch, off-load my digital images etc? I plan on hitting the British Museum but was wondering what geeky things to do that are in London that might be worth going to and any tips hints on overseas travel for geeks? I travel quite a bit in the states but this will be my first trip overseas and want to make the best of my stay in merry old England. What words of advice do you travel seasoned geeks have for me?"

pdclarry writes "A recent study by scientists at the American Museum of Natural History and Columbia University found that a piece of tuna sushi may not be tuna at all: 'A piece of tuna sushi has the potential to be an endangered species, a fraud or a health hazard,' wrote the authors. 'All three of these cases were uncovered in this study.' The study, published in PLoS ONE examined 68 samples of tuna sushi purchased from 31 restaurants in Manhattan (New York City) and Denver, Colorado. Some of these were from endangered species, others were not as labeled, and some were not tuna at all. Of these last, five samples labeled as 'white tuna' were from a toxic fish, Escolar, which is a gempylid species banned for sale in Italy and Japan due to health concerns. 'It can cause gastrointestinal symptoms ranging from mild and rapid passage of oily yellow or orange droplets, to severe diarrhea with nausea and vomiting. The milder symptoms have been referred to as keriorrhea [i.e. flow of wax in Greek].' Fraud in sushi is not new; Slashdot also reported study on mislabeling in 2008. This new study shows that some sushi can actually make you sick. The study was also covered by Wired."

jamie writes with this snippet from the UK's Independent: "The world is now firmly on course for the worst-case scenario in terms of climate change, with average global temperatures rising by up to 6C by the end of the century, leading scientists said yesterday. ... [The study] found that there has been a 29 per cent increase in global CO2 emissions from fossil fuel between 2000 and 2008, the last year for which figures are available. On average, the researchers found, there was an annual increase in emissions of just over 3 per cent during the period, compared with an annual increase of 1 per cent between 1990 and 2000. Almost all of the increase this decade occurred after 2000 and resulted from the boom in the Chinese economy. The researchers predict a small decrease this year due to the recession, but further increases from 2010."

We've mentioned the tantalizing possibilities of augmented reality here several times, including Microsoft's stab (using scene recognition) as an information overlay for cell phones, and some display technologies that could make a Terminator-style information overlay on the real world possible without even looking down at a screen, including both glasses with microdisplays and contact lenses. An anonymous reader points to this two-part review of several cell phone apps, in which the writer has "tested several mobile augmented reality browsers and their ability to find places to eat and function as a tourist guide by identifying tourist attractions in London," writing, "This is the first review I have seen where all the browsers have been compared together; what's interesting is all the browsers use different data sources, and so either miss popular locations or give the wrong location."

An anonymous reader writes "It's great that unelected bureaucrats in California are clamoring to save energy, but when they target your big-screen TVs for elimination, consumers and manufacturers are apt to declare war. CEDIA and the CEA are up in arms over this. Audioholics has an interesting response that involves setting the TVs in 'SCAM' mode to meet the energy criteria technically without having to add additional cost or increase costs to consumers. 'In this mode, the display brightness/contrast settings would be set a few clicks to the right of zero, audio would be disabled and backlighting would be set to minimum. The power consumption should be measured in this mode much like an A/V receiver power consumption is measured with one channel driven at full rated power and the other channels at 1/8th power.' This is an example of an impending train wreck of unintended consequences, and many are grabbing the popcorn and pulling up chairs to watch."
