MRI Software Bugs Could Upend Years Of Research

Tue, 05/07/2016 - 3:20pm
An anonymous reader shares a report on The Register: A whole pile of "this is how your brain looks like" MRI-based science has been invalidated because someone finally got around to checking the data. The problem is simple: to get from a high-resolution magnetic resonance imaging scan of the brain to a scientific conclusion, the brain is divided into tiny "voxels". Software, rather than humans, then scans the voxels looking for clusters. When you see a claim that "scientists know when you're about to move an arm: these images prove it", they're interpreting what they're told by the statistical software. Now, boffins from Sweden and the UK have cast doubt on the quality of the science, because of problems with the statistical software: it produces way too many false positives. In this paper at PNAS, they write: "the most common software packages for fMRI analysis (SPM, FSL, AFNI) can result in false-positive rates of up to 70%. These results question the validity of some 40,000 fMRI studies and may have a large impact on the interpretation of neuroimaging results."

TP-LINK Loses Control of Two Device Configuration Domains

Tue, 05/07/2016 - 2:40pm
Reader Orome1 writes: Security researcher Amitay Dan warns that, a domain through which TP-LINK router owners can configure their devices, is no longer owned by the company, and that this fact could be misused by malware peddlers. TP-LINK has confirmed that they no longer own the domain in question, and will not be trying to buy it from the unknown seller for now. Instead, they intend to change the domain in the manuals to a newer one that's already in use.ComputerWorld has more details.

Verizon To Hike Prices On Plans But Offer More Data

Tue, 05/07/2016 - 2:00pm
Roger Cheng, reporting for CNET: Big changes are afoot at Verizon. The nation's largest wireless carrier is set to unveil changes to its plans that will make them more expensive, but will also include more data, according to someone familiar with the changes. The low-end "S" plan will go up by $5 to $35 a month, but will include 2 gigabytes of data, twice as much as before. The "M" plan will go up by $5 to $50 a month, while its data will rise from 3GB to 4GB. The "L" plan will go up by $10 to $70 a month, while data increases from 6GB to 8GB. The "XL" plan will go up by $10 to $90 a month, but you'll get 16GB, up from 12GB before. Lastly, the "XXL" plan will cost $10 more at $110 a month, but you will get 24GB instead of 18GB. The changes are part of a broader overhaul of its plans, which will also include a rollover data program called "Carryover Data," a new way to avoid overage fees, and better access to Canada and Mexico. The move reflects a heightened competitive environment, one in which smaller rivals T-Mobile and Sprint have begun winning away customers through aggressive offers. Many of these changes mimic offers already available at the other carriers.

Historic Route 66 To Feature Solar Road Technology

Tue, 05/07/2016 - 1:00pm
An anonymous reader writes: The Missouri Department of Transportation (MoDOT) has announced plans to upgrade a small stretch of the historic Route 66 roadway with solar-powered panels. The panels, which are created by Solar Roadways, can support the weight of cars, feature built-in LEDs to create light-up road markings, and can be used to generate electricity to donate back to the grid. The company has won a number of contracts with the U.S. Department of Transportation, though it's unlikely we'll see solar-powered roadways throughout the country anytime soon. MoDOT said it hopes to lay the first panels starting with the Historic Route 66 Welcome Center by the end of the year, The Kansas City Star reports. SolarCity released a new report recently that says their solar power systems have a usable lifetime of at least 35 years, which is 40% longer than what the market expects.

NASA's Juno Space Probe Enters Orbit Around Jupiter

Tue, 05/07/2016 - 10:00am
An anonymous reader quotes a report from CNN: NASA says it has received a signal from 540 million miles across the solar system, confirming its Juno spacecraft has successfully started orbiting Jupiter, the largest planet in our solar system. "Welcome to Jupiter!" flashed on screens at mission control at NASA's Jet Propulsion Lab in Pasadena, California. The probe had to conduct a tricky maneuver to slow down enough to allow it to be pulled into orbit: It fired its main engine for 35 minutes, effectively hitting the brakes to slow the spacecraft by about 1,212 miles per hour (542 meters per second). Juno was launched nearly five years ago on a mission to study Jupiter's composition and evolution. It's the first spacecraft to orbit Jupiter since Galileo. The largest planet in our solar system, Jupiter is a huge ball of gas 11 times wider than Earth and 300 times more massive than our planet. Researchers think it was the first planet to form and that it holds clues to how the solar system evolved. Juno is a spinning, robotic probe as wide as a basketball court. It will circle Jupiter 37 times for 20 months, diving down to about 2,600 miles (4,100 kilometers) above the planet's dense clouds. The seven science instruments on board will study Jupiter's auroras and help scientists better understand the planet's origins, structure, atmosphere and magnetosphere. An onboard color camera called JunoCam will take "spectacular close-up, color images" of Jupiter, according to NASA. Juno launched from Cape Canaveral on August 5, 2011, which is some 445 million miles (716 million kilometers) away from Jupiter. Juno has however traveled a total distance of 1,740 million miles (2,800 million kilometers) to reach Jupiter as it had to make a flyby of Earth to help pick up speed. "After a 1.7 billion mile journey, we hit our burn targets within one second, on a target that was just tens of kilometers large," said Nybakken, Juno Project Manger. "That's how well the Juno spacecraft performed tonight."

Microsoft Xbox Project Scorpio Puts Out 6 TFLOPs On Par With Current Gaming PCs

Tue, 05/07/2016 - 7:00am
MojoKid quotes a report form HotHardware: Microsoft is hoping to usher in a new era in console gaming just over a year from now. While the company is just a month away from launching the Xbox One S refresh in the U.S., Project Scorpio is the console that really has gamers talking. During E3, Microsoft provided scant details on the console, only cluing us in to the fact that it would support virtual reality, 4K gaming, and push 6 TFLOPs of computing power. Mateusz Tomaszkiewicz, CD Projekt Red's Principal Narrative Designer, had a few things to say about that last bullet point regarding compute performance. If you recall, AMD's newly introduced Radeon RX 480 offers peak performance of 5.8 TFLOPs, which puts it in close proximity of Microsoft's Project Scorpio. But of course, trying to compare consoles to PCs using this stat alone isn't exactly apples to oranges, though Tomaszkiewicz explains, "For sure [Scorpio] will have better looking games," Tomaszkiewicz said. "If this was available when we were working on Wild Hunt, I would expect similar quality that we have on PC right now or even better maybe." HotHardware's report goes on to mention that once new console hardware is introduced, it's frozen for years at a time without any updates. Therefore, it would only be a short while before PCs would completely outcompete it in terms of performance. Also, given the fact that Project Scorpio is not arriving until late 2017 at the earliest, the 6 TFLOPs of power won't seem like much when compared to the new cycle of high-end GPUs with far superior performance. Tomaszkiewicz agrees, adding, "New graphic cards are being released very often and more often than the new consoles being released. So I think it will put Scorpio on par with the PC is that we have at that point. But I think PC is growing so fast that it'll outpace [Scorpio]."
