First Proven Diagnostic Test For Alzheimer's 66

Posted by kdawson from the peace-of-mind-or-otherwise dept.
An anonymous reader writes "A test that can confirm or rule out Alzheimer's disease at an early stage has been shown effective by US pathologists. 'With this test, we can reliably detect and track the progression of Alzheimer's disease,' said lead researcher Leslie Shaw with the University of Pennsylvania's Alzheimer's Disease Neuroimaging Initiative in Philadelphia. ... The new test is detailed in the journal Annals of Neurology. It measures the cerebral-spinal fluid concentration of two biochemicals associated with the disease — amyloid beta42 peptide and tau protein."

Submission + - 'Baffling' Link between Autism and Vinyl Flooring (sciam.com)

Submitted by SpuriousLogic
SpuriousLogic writes: Swedish children who live in homes with vinyl floors are more likely to have autism, according to a new study, but what's behind the link is unclear.
Children who live in homes with vinyl floors, which can emit chemicals called phthalates, are more likely to have autism, according to research by Swedish and U.S. scientists published Monday.
The study of Swedish children is among the first to find an apparent connection between an environmental chemical and autism.

Locating the Real MySQL 335

Posted by kdawson from the place-your-bets dept.
An anonymous reader writes "In a blog post, Patrick Galbraith, an ex-core engineer on the MySQL Server team, raises the question: "What is the official branch of MySQL?" With Monty Widenius having left Sun and forked off MySQL for MariaDB, and Brian Aker running the Drizzle fork inside of Sun, where is the official MySQL tree? Sun may own the trademark, but it looks like there is doubt as to whether they are still the maintainers of the actual codebase after their $1B acquisition of the code a year ago. Smugmug's Don MacAskhill, who is the keynote at the upcoming MySQL Conference, has commented that he is now using the Percona version of MySQL, and is no longer relying on Sun's."

IBM Tries To Patent Offshoring 242

Posted by ScuttleMonkey from the riaa-business-method dept.
Ian Lamont writes "IBM has filed a patent application that covers offshoring employees. Application 20090083107, dated March 26, 2009, is a 'method and system for strategic global resource sourcing.' Figure 2 gives a pretty good idea of what's involved — it shows boxes labelled 'Engineer,' 'HR,' and 'Programmer' with crossing arrows pointing to cylinders labelled 'India,' 'China,' and 'Hungary.' The article speculates that IBM may apply the methodology to its own staff — it reportedly plans to lay off thousands of employees and has even started a program to have IBM workers transfer to other countries at local wages."

UK Libel Law Is a Global Threat To Web Free Speech 363

Posted by Soulskill from the careful-what-you-tweet dept.
uctpjac writes "London media lawyer Emily MacManus argues that UK libel law has three features which make it the 'defamation tourism' capital of the world and a serious threat to Web free speech. First, there is no free speech presumption in the UK as there is, for example, in the US. Second, every access of a Web page is considered to be a separate act of publication in the UK (unlike the US, where 'original publication' holds). Third, 'no-win-no-fee' libel litigation is now allowed in the UK. If any blog, anywhere, publishes something you'd like taken down, threaten libel action in the UK: no one except the super-rich can afford to even take these cases to court, so media lawyers advise publishers to 'take it down, take it down quickly, take it down again.' There's not much chance that the judges will move the law any time soon because they just aren't seeing the cases that could cause them to set new precedent."

Why Toddlers Don't Do What They're Told 412

Posted by kdawson from the mine-mine-mine dept.
Hugh Pickens writes "New cognitive research shows that 3-year-olds neither plan for the future nor live completely in the present, but instead call up the past as they need it. 'There is a lot of work in the field of cognitive development that focuses on how kids are basically little versions of adults trying to do the same things adults do, but they're just not as good at it yet. What we show here is they are doing something completely different,' says professor Yuko Munakata at the University of Colorado at Boulder. Munakata's team used a computer game and a setup that measures the diameter of the pupil of the eye to determine mental effort to study the cognitive abilities of 3-and-a-half-year-olds and 8-year-olds. The research concluded that while everything you tell toddlers seems to go in one ear and out the other, the study found that toddlers listen, but then store the information for later use. 'For example, let's say it's cold outside and you tell your 3-year-old to go get his jacket out of his bedroom and get ready to go outside,' says doctoral student Christopher Chatham. 'You might expect the child to plan for the future, think "OK it's cold outside so the jacket will keep me warm." But what we suggest is that this isn't what goes on in a 3-year-old's brain. Rather, they run outside, discover that it is cold, and then retrieve the memory of where their jacket is, and then they go get it.'"

Red Hat — Stand Alone Or Get Bought? 199

Posted by Soulskill from the all-about-the-benjamins dept.
head_dunce writes "It seems that this economy has inspired a lot of businesses to move to Linux, with Red Hat posting profits that beat everyone's expectations. There's a dark side to being a highly profitable company in a down economy, though — now there are talks of Citigroup and Oracle wanting to buy Red Hat. For a while now, we've been watching Yahoo fend off Carl Icahn and Steve Ballmer so that they could stay independent, but the fight seems to be a huge distraction for Yahoo, with lots of energy (and money) invested. Will Red Hat stay independent? What potential buyer would make for a good parent company?"

Euro Parliament Warns Against Overzealous IP Enforcement 73

Posted by timothy from the death-to-whistlers-of-beatles-tunes dept.
An anonymous reader writes "Days after New Zealand dropped its support for the 'three strikes and you're out' approach for terminating Internet subscribers, the European Parliament has now similarly rejected the proposed approach. Today the EP adopted a new report on security and fundamental freedoms on the Internet that expressly rejects disproportionate measures for IP enforcement and the use of excessive access restrictions placed by IP rights holders."

With a Computer Science Degree, an Old Man At 35? 918

Posted by timothy from the logan's-run-time dept.
GrApHiX42 writes "I pissed away my 20s and now I want to go to school and get a bachelor's degree in computer science. The thing is, I'll be 35 when I get out of school, and I've read on numerous sites that there seems to be some ageism going on in the IT industry when it comes to older geeks. What have some of the 'older' Slashdot readers experienced as far as being replaced or just plain not getting hired because IT is a 'young man's game'?"

Huge Supernova Baffles Scientists 358

Posted by timothy from the like-laser-pointers-to-cats dept.
Iddo Genuth writes "Scientists from the Weizmann Institute of Science in Israel and San Diego State University have observed an explosion of a star 50 times larger than the sun. In what they call a 'first observation of its kind' the scientists were able to notice that most of the star's mass collapsed in on itself, resulting in a creation of a large black hole. While exploding stars, or 'supernovae,' aren't unprecedented, this star, which lay about 200 million light years away from earth and was million times brighter than the Sun, has exploded as a supernova at a much earlier date than the one predicted by astronomers."

Researchers Can ID Anonymous Twitterers 108

Posted by timothy from the 140-shady-characters dept.
narramissic writes "In a paper set to be delivered at an upcoming security conference, University of Texas at Austin researchers showed how they were able to identify people who were on public social networks such as Twitter and Flickr by mapping out the connections surrounding their network of friends. From the ITworld article: 'Web site operators often share data about users with partners and advertisers after stripping it of any personally identifiable information such as names, addresses or birth dates. Arvind Narayanan and fellow researcher Vitaly Shmatikov found that by analyzing these 'anonymized' data sets, they could identify Flickr users who were also on Twitter about two-thirds of the time, depending on how much information they have to work with.'"

Technology Scans Giant Fish Schools 31

Posted by timothy from the for-great-harvests dept.
rhettb writes "Employing a new technology, MIT engineers have studied the origins of a mass gathering of hundreds of millions of fish and their subsequent migration. This is the first time a mass migration of animals has been studied from beginning to end, according to their paper published in Science. Until now biologists have depended on theory rather than data from the field, employing computer simulations and experiments in the lab. The MIT engineers employed a new technology, Ocean Acoustic Waveguide Remote Sensing (OAWRS), to record the mass migrations in detail. Developed by Makris and his team in 2006, the OAWRS is able to take images of an area 62 miles (100 kilometers) in diameter every 75 seconds. The system relies on sending sound waves that locate objects by bouncing off of them."

Old-School Keyboard Makes Comeback of Sorts 519

Posted by timothy from the thrift-store-treasure dept.
CharlotteShma writes "Some old writer once said that in order to keep going, he needed to hear the scratch of the pen on the page. Some self-proclaimed keyboard aficionados would make the same argument for computer keyboards. Is it possible that the old 'clicky' keyboards are making a comeback? Now that we've replaced the old buckling springs with rubber domes, our keyboards are only getting quieter and quieter. According to the people at Unicomp Inc., all keyboards made since the early 1990s are, frankly, no good. They still use and produce vintage IBM Model M keyboards in their small factory in Lexington, Kentucky. The IBM Model M keyboards are ugly, built like tanks, and, most importantly, have a spring under each key which clicks when you press it." Not sure what's ugly about them — most other keyboards are ugly, when you shut your eyes.

Laser Sniffing Captures Typed Keystrokes From 50-100 Feet 146

Posted by timothy from the shoot-back dept.
Death Metal writes "Chief Security Engineer Andrea Barisani and hardware hacker Daniele Bianco used handmade laser microphone device and a photo diode to measure the vibrations, software for analyzing the spectrograms of frequencies from different keystrokes, as well as technology to apply the data to a dictionary to try to guess the words. They used a technique called dynamic time warping that's typically used for speech recognition applications, to measure the similarity of signals. Line-of-sight on the laptop is needed, but it works through a glass window, they said. Using an infrared laser would prevent a victim from knowing they were being spied on." (This is the same team that was able to pick up the electromagnetic signals emitted by PS/2 keyboards.)

Microsoft Shoots Own Foot In Iceland 476

Posted by kdawson from the blood-from-a-stone-middleman dept.
David Gerard writes "The Microsoft Certified Partner model is: an MCP buys contracts from Microsoft and sells them to businesses as a three-year timed contract, payable in annual installments. Iceland's economy has collapsed, so 1500 businesses have gone bankrupt and aren't paying the fees any more. But Microsoft has told the MCPs: 'Our deal was with you, not them. Pay up.' The MCPs that don't go bankrupt in turn are moving headlong to Free Software, taking most of the country with them. (Warning: link contains strong language and vivid imagery.)"
