Microsoft Releases Out-of-Band Security Patch For Windows

mrspoonsi writes Microsoft has announced today that they will be pushing an out-of-band security patch today. The patch, which affects nearly all of the company’s major platforms, is rated ‘critical’ and it is recommended that you install the patch immediately. The patch is rated ‘critical’ because it allows for elevation of privileges and will require a restart. The platforms that are affected include: Windows Server 2003, Windows Vista, Windows Server 2008, Windows 7, Windows 8 and 8.1, Windows Server 2012 and Windows Server 2012 R2, Windows RT and Windows RT 8.1 and Windows 10 Technical Preview customers are affected, too.

Major Brain Pathway Rediscovered After Century-old Confusion, Controversy

vinces99 writes A couple of years ago a scientist looking at dozens of MRI scans of human brains noticed something surprising: A large fiber pathway that seemed to be part of the network of connections that process visual information that wasn’t mentioned in any modern-day anatomy textbooks. “It was this massive bundle of fibers, visible in every brain I examined, ” said Jason Yeatman, a research scientist at the University of Washington’s Institute for Learning & Brain Sciences. “… As far as I could tell, it was absent from the literature and from all major neuroanatomy textbooks.'”With colleagues at Stanford University, Yeatman started some detective work to figure out the identity of that mysterious fiber bundle. The researchers found an early 20th century atlas that depicted the structure, now known as the vertical occipital fasciculus. But the last time that atlas had been checked out was 1912, meaning the researchers were the first to view the images in the last century. They describes the history and controversy of the elusive pathway in a paper published Nov. 17 in the Proceedings of the National Academy of Sciences. You’d think that we’d have found all the parts of the human body by now, but not necessarily. Read more of this story at Slashdot.

Apple Disables Trim Support On 3rd Party SSDs In OS X

MojoKid (1002251) writes One of the disadvantages to buying an Apple system is that it generally means less upgrade flexibility than a system from a traditional PC OEM. Over the last few years, Apple has introduced features and adopted standards that made using third-party hardware progressively more difficult. Now, with OS X 10.10 Yosemite, the company has taken another step down the path towards total vendor lock-in and effectively disabled support for third-party SSDs. We say “effectively” because while third-party SSDs will still work, they’ll no longer perform the TRIM garbage collection command. Being able to perform TRIM and clean the SSD when its sitting idle is vital to keeping the drive at maximum performance. Without it, an SSD’s real world performance will steadily degrade over time. What Apple did with OS X 10.10 is introduce KEXT (Kernel EXTension) driver signing. KEXT signing means that at boot, the OS checks to ensure that all drivers are approved and enabled by Apple. It’s conceptually similar to the device driver checks that Windows performs at boot. However, with OS X, if a third-party SSD is detected, the OS will detect that a non-approved SSD is in use, and Yosemite will refuse to load the appropriate TRIM-enabled driver.

81% of Tor Users Can Be De-anonymized By Analysing Router Information

An anonymous reader writes A former researcher at Columbia University’s Network Security Lab has conducted research since 2008 indicating that traffic flow software included in network routers, notably Cisco’s ‘Netflow’ package, can be exploited to deanonymize 81.4% of Tor clients. Professor Sambuddho Chakravarty, currently researching Network Anonymity and Privacy at the Indraprastha Institute of Information Technology, uses a technique which injects a repeating traffic pattern into the TCP connection associated with an exit node, and then compares subsequent aberrations in network timing with the traffic flow records generated by Netflow (or equivalent packages from other router manufacturers) to individuate the ‘victim’ client. In laboratory conditions the success rate of this traffic analysis attack is 100%, with network noise and variations reducing efficiency to 81% in a live Tor environment. Chakravarty says: ‘it is not even essential to be a global adversary to launch such traffic analysis attacks. A powerful, yet non- global adversary could use traffic analysis methods [] to determine the various relays participating in a Tor circuit and directly monitor the traffic entering the entry node of the victim connection.’ Read more of this story at Slashdot.

An Applied Investigation Into Graphics Card Coil Whine

jones_supa writes We all are aware of various chirping and whining sounds that electronics can produce. Modern graphics cards often suffer from these kind of problems in form of coil whine. But how widespread is it really? Hardware Canucks put 50 new graphics cards side-by-side to compare them solely from the perspective of subjective acoustic disturbance. NVIDIA’s reference platforms tended to be quite well behaved, just like their board partners’ custom designs. The same can’t be said about AMD since their reference R9 290X and R9 290 should be avoided if you’re at all concerned about squealing or any other odd noise a GPU can make. However the custom Radeon-branded SKUs should usually be a safe choice. While the amount and intensity of coil whine largely seems to boil down to luck of the draw, at least most board partners are quite friendly regarding their return policies concerning it.

Researchers Forecast the Spread of Diseases Using Wikipedia

An anonymous reader writes Scientists from Los Alamos National Laboratory have used Wikipedia logs as a data source for forecasting disease spread. The team was able to successfully monitor influenza in the United States, Poland, Japan, and Thailand, dengue fever in Brazil and Thailand, and tuberculosis in China and Thailand. The team was also able to forecast all but one of these, tuberculosis in China, at least 28 days in advance. Read more of this story at Slashdot.

Researchers Demonstrate Electrically Activated Micro-Muscles

mpicpp sends news of research at the University of Michigan in which a self-assembling chain of particles can be used as tiny, electrically-activated muscles. The team started with particles similar to those found in paint, with diameters of about a hundredth the width of a strand of hair. They stretched these particles into football shapes and coated one side of each football with gold. The gilded halves attracted one another in slightly salty water—ideally about half the salt concentration in the sports drink Powerade. The more salt in the water, the stronger the attraction. Left to their own devices, the particles formed short chains of overlapping pairs, averaging around 50 or 60 particles to a chain. When exposed to an alternating electric field, the chains seemed to add new particles indefinitely. But the real excitement was in the way that the chains stretched. … While the force generated by the fibers is about 1, 000 times weaker than human muscle tissue per unit area, it may be enough for microbots.

Multi-Process Comes To Firefox Nightly, 64-bit Firefox For Windows ‘Soon’

An anonymous reader writes with word that the Mozilla project has made two announcements that should make hardcore Firefox users very happy. The first is that multi-process support is landing in Firefox Nightly, and the second is that 64-bit Firefox is finally coming to Windows. The features are a big deal on their own, but together they show Mozilla’s commitment to the desktop version of Firefox as they both improve performance and security. The news is part of a slew of unveilings from the company on the browser’s 10th anniversary — including new Firefox features and the debut of Firefox Developer Edition.

Apple Releases iMessage Deregistration Utility

tlhIngan writes When moving from an iPhone to something else, if you were an avid user of iMessage, you may find your messages missing, especially from iOS-using friends. Indeed, it has been such a problem that there are even lawsuits about it. While Apple has maintained that users can always switch off iMessage, that only works if you still have your iOS device. Unless one also has other iOS devices or a Mac, they may not even realize their friends have been sending messages that are queued up on Apple’s services via iMessage. Well, that problem has been resolved with Apple creating a deregistration utility to remove your phone number from the iMessage servers so friends will no longer send you texts via iMessage that you can no longer receive. It’s a two-step process involving proof of number ownership (via regular SMS) before deregistration takes place. Read more of this story at Slashdot.

Satellites Spot Hidden Villages In Amazon

sciencehabit writes The Amazon is home to perhaps dozens of isolated tribes who make their living far off the grid from the wider society, growing crops and hunting and gathering in the forest. These reclusive peoples are threatened by drug running, illegal logging, and highway construction, even if they dwell in ‘protected’ reserves in Peru or Brazil; one group, apparently pushed out of its lands, made contact this summer. Now, researchers have a new way of examining their fate without disruptive and frightening flyovers by aircraft. Researchers use high-resolution WorldView or GeoEye satellite images to monitor demographic changes in isolated Amazon tribes. The scientists got location and population estimates for five isolated villages along the Brazil-Peru border from Brazilian government reports and other sources. Then they examined 50-centimeter resolution satellite images taken in 2006, 2012, and 2013 and could spot the peoples’ horticultural fields and characteristic pattern of either longhouses or clusters of small houses; these villages could be clearly differentiated from the transient camps of illegal loggers or drug runners.
