Robotic Audi To Brave Pikes Peak Without a Driver 197

Scifi83 writes "A team of researchers at the Center for Automotive Research at Stanford (CARS) has filled the trunk of an Audi TTS with computers and GPS receivers, transforming it into a vehicle that drives itself. The car will attempt Pikes Peak without a driver at race speeds, something that's never been done."

New Brain Scans Can Spot PTSD 107

Neuroscientists think they may have found a scientific method to identify post-traumatic stress disorder (PTSD) using a brain imaging method called magnetoencephalography (MEG). In the test study, the scientists studied 74 vets with PTSD and 250 civilians without and were able to spot the PTSD sufferers with 90% accuracy. "MEG machines are a fast, sensitive and accurate way to measure electric activity in the brain. Whereas CT scans and MRIs record brain signals every few seconds, MEGs can do it by the millisecond, catching biomarkers and brain activity that the other tests inevitably miss. The study could be a breakthrough for the military, who've been scrambling to address a surge in post-traumatic symptoms among newly returning vets. Right now, troops are evaluated by mental health experts, but diagnosis is a crap-shoot: symptoms can take years to show up, and vary from person to person, even among those exposed to the same traumas. The Pentagon's already been pushing for more objective, systematized diagnosis tools, like portable at-home sleep monitors and genetic testing to detect PTSD vulnerability. They've even launched a program to create stress-mitigating pharmaceuticals."

Flickr Yanks Image of Obama As Joker 869

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."

Wikipedia Approaches Its Limits 564

Reservoir Hill writes "The Guardian reports that a study by Ed H Chi demonstrates that the character of Wikipedia has changed significantly since Wikipedia's first burst of activity between 2004 and 2007. While the encyclopedia is still growing overall, the number of articles being added has reduced from an average of 2,200 a day in July 2007 to around 1,300 today while at the same time, the base of highly active editors has remained more or less static. Chi's team discovered that the way the site operates had changed significantly from the early days, when it ran an open-door policy that allowed in anyone with the time and energy to dedicate to the project. Today, they discovered, a stable group of high-level editors has become increasingly responsible for controlling the encyclopedia, while casual contributors and editors are falling away. 'We found that if you were an elite editor, the chance of your edit being reverted was something in the order of 1% — and that's been very consistent over time from around 2003 or 2004,' says Chi. 'For editors that make between two and nine edits a month, the percentage of their edits being reverted had gone from 5% in 2004 all the way up to about 15% by October 2008. And the 'onesies' — people who only make one edit a month — their edits are now being reverted at a 25% rate.' While Chi points out that this does not necessarily imply causation, he suggests it is concrete evidence to back up what many people have been saying: that it is increasingly difficult to enjoy contributing to Wikipedia unless you are part of the site's inner core of editors. Wikipedia's growth pattern suggests that it is becoming like a community where resources have started to run out. 'As you run out of food, people start competing for that food, and that results in a slowdown in population growth and means that the stronger, more well-adapted part of the population starts to have more power.'"

F-22 Raptor Cancelled 829

BayaWeaver writes "Slate reports that the F-22 Raptor has been cancelled by the Senate. At an estimated price tag of $339 million per aircraft, even the powerful military-industrial-congressional complex couldn't keep this Cold War program alive in these hard times. They look very cool though and have appeared in movies like Hulk and Transformers. But not to worry too much about the future of the military-industrial-congressional complex: the F-35 Lightning II begins production next year! As a side note, in 2007 a squadron of Raptors became deaf, dumb and blind when they flew over the International Date Line."

NASA's Skylab $400 Littering Fine Paid By DJ 111

astroengine writes "Space Disco speaks with a Californian radio DJ about his role in raising, and paying, NASA's 30-year old littering fine levied by a Western Australian town. Skylab parts fell on Esperance in 1979, but the space agency's refusal to pay $400 has resulted in an entertaining annual grudge. Now the Barstow radio DJ is guest of honor at this weekend's 30th anniversary celebrations in Oz and the two small towns at opposite ends of the Pacific will be twinned... all because Skylab had a messy re-entry..."

Passenger Avoids Delay By Fixing Plane Himself 178

It would be a shame if an engineer on a recent Thomas Cook Airlines flight doesn't get a complimentary first class upgrade every time he flies. The engineer was on flight TCX9641 when it was announced that the trip would be delayed eight hours, while a mechanic was flown in to fix a problem. Luckily for the other passengers, the engineer happened to work for Thomsonfly Airlines, which has a reciprocal maintenance agreement with Thomas Cook. After about 35 minutes the man fixed the problem and the flight was on its way. A spokeswoman for Thomas Cook said, "When they announced there was a technical problem he came forward and said who he was. We checked his licence and verified he was who he said he was, and he was able to fix the problem to avoid the delay. We are very grateful that he was on the flight that day."

Your Browser History Is Showing 174

tiffanydanica writes "For a lot of us our browser history is something we consider private, or at least not something we want to expose to every website we visit. Web2.0collage is showing just how easy it is (with code!) for sites to determine what sites you visit. When you visit the site it sniffs your browser history, and creates a collage of the (safe for work) sites that you visit. It is an interesting application of potentially scary technology (imagine a job application site using this to screen candidates). You can jump right into having your history sniffed if you so desire. While the collages are cool on their own merit, they also serve as an illustration of the privacy implications of browser history sniffing."

Camara Goes On Offense Against the RIAA 316

whisper_jeff writes "Ars has an excellent write up outlining how Kiwi Camara (Jammie Thomas-Rasset's new lawyer) is following the 'Best Defense is a Good Offense' philosophy and going on the attack against the RIAA. Not content to just defend his client, he is laying siege against the RIAA's entire campaign and beginning the work of dismantling it from the bottom up, starting with the question of whether they actually do own the copyrights that were allegedly infringed. And, if you're thinking this is good for everyone who's been harassed by the RIAA, you'd be right — Camara, along with Harvard Law professor Charles Nesson, plans to file a class-action suit seeking to force the RIAA to return all the (ill-gotten) money they've earned from their litigation campaign." We first discussed the efforts of Nesson and Camara to thwart the RIAA last month.

Computers Key To Air France Crash 911

Michael_Curator writes "It's no secret that commercial airplanes are heavily computerized, but as the mystery of Air France Flight 447 unfolds, we need to come to grips with the fact that in many cases, airline pilots' hands are tied when it comes to responding effectively to an emergency situation. Boeing planes allow pilots to take over from computers during emergency situations, Airbus planes do not. It's not a design flaw — it's a philosophical divide. It's essentially a question of what do you trust most: a human being's ingenuity or a computer's infinitely faster access and reaction to information. It's not surprising that an American company errs on the side of individual freedom while a European company is more inclined to favor an approach that relies on systems. As passengers, we should have the right to ask whether we're putting our lives in the hands of a computer rather than the battle-tested pilot sitting up front, and we should have right to deplane if we don't like the answer."

Space Station Crew Drinks Recycled Urine 349

An anonymous reader writes "After the astronauts on the International Space Station finished up their communications with Space Shuttle Atlantis yesterday, the crew on the Space Station did something that no other astronaut has ever done before — drank recycled urine and sweat. The previous shuttle crew that recently returned to Earth brought back samples of the recycled water to make sure it was safe to drink, and all tests came back fine. So on Wednesday, the crew took their recycled urine and said 'cheers' together and toasted the researches and scientists that made the Urine Recycler possible. After drinking the water, they said the taste was great! They also said the water came with labels on it that said 'drink this when real water is over 200 miles away.'"

Cola Consumption Can Lead To Muscle Problems 420

wjousts writes "As I'm sure many Slashdot readers live almost exclusively on cola drinks, a new warning from doctors: 'Doctors have issued a warning about excessive cola consumption after noticing an increase in the number of patients suffering from muscle problems, according to the June issue of IJCP, the International Journal of Clinical Practice. ... 'Evidence is increasing to suggest that excessive cola consumption can also lead to hypokalaemia, in which the blood potassium levels fall, causing an adverse effect on vital muscle functions.' And sorry, diet colas aren't any better."

Special Effects Lessons From JJ Abrams' Star Trek 461

brumgrunt writes "JJ Abram's hugely successful — on many levels — reboot of Star Trek has, for Den Of Geek, brought to the fore a lesson about special effects that many movie makers have been missing. Surely it's time now that special effects were actually used properly?" (The new film is not without some goofs, though only a few of the ones listed by Movie Mistakes' nitpickers are sciency.)
