Smart Rendering For Virtual Reality

Slashdot - Fri, 20/02/2015 - 4:41pm
An anonymous reader writes: Researchers from Intel have been working on new methods for improving the rendering speed for modern wide-angle head-mounted displays like the Oculus Rift and Google Cardboard. Their approach makes use of the fact that because of the relatively cheap and lightweight lenses the distortion astigmatism happens: only the center area can be perceived very sharp, while with increasing distance from it, the perception gets more and more blurred. So what happens if you don't spend the same amount of calculations and quality for all pixels? The blog entry gives hints to future rendering architectures and shows performance numbers.

Independent home living or healthcare facility? Web tool to speed data collection

Science Daily - Fri, 20/02/2015 - 4:08pm
By 2030, one in five Americans will be age 65 or older. To understand the role neighborhoods play in seniors' ability to 'age in place' -- living safely and independently in one's home of choice rather than in a healthcare facility -- researchers created a web application that speeds up researchers' data collection.

Safety, life-saving efficacy of statins have been exaggerated, says scientist

Science Daily - Fri, 20/02/2015 - 4:08pm
Statins, the cholesterol-lowering drugs prescribed to prevent heart attacks, are not as effective nor as safe as we have been led to believe, researchers say. Statins produce a dramatic reduction in cholesterol levels, but have failed to substantially improve cardiovascular outcomes, they add, stating that 'statistical deception' has been used to inflate claims about their effectiveness.

Lenovo To Wipe Superfish Off PCs

Slashdot - Fri, 20/02/2015 - 3:57pm
An anonymous reader send news from the Wall Street Journal, where Lenovo CTO Peter Hortensius said in an interview that the company will roll out a software update to remove the Superfish adware from its laptops. "As soon as the programmer is finished, we will provide a tool that removes all traces of the app from people’s laptops; this goes further than simply uninstalling the app. Once the app-wiping software is finished tonight or tomorrow, we’ll issue a press release with information on how to get it." When asked whether his company vets the software they pre-install on their machines, he said, "Yes, we do. Obviously in this case we didn't do enough. The intent of loading this tool was to help enhance our users’ shopping experience. The feedback from users was that it wasn’t useful, and that’s why we turned it off. Our reputation is everything and our products are ultimately how we have our reputation."

How to Build a Ski Mountain from Scratch… in 80-Degree Weather

Wired News - Fri, 20/02/2015 - 3:25pm

The Arroyo Seco in Pasadena, California is a dusty depression, where shrubs and cacti hold hillsides together and highway bridges cross overhead. Like elsewhere in Los Angeles, the water that does flow down the streambed is confined to a concrete ditch; most of the year, only a thin, slimy ribbon trickles down its center. As […]

Immune cells: Learning from experience

Science Daily - Fri, 20/02/2015 - 3:15pm
Immunologists have shown that our immune cells can learn on the job. Even better, some cells remember what they have learned, and can apply it in response to future challenges. The research focused on T-helper cells, a type of T cell that helps other immune cells by releasing messenger substances or cytokines.

Reducing energy efficiency boosts calorie burning in muscle

Science Daily - Fri, 20/02/2015 - 3:15pm
A targeted approach that overrides muscles' intrinsic energy efficiency and allows muscle to burn more energy, even during low to moderate exercise, has been developed by scientists. The new findings might provide the basis of a therapy that could help people get a head start on losing weight by helping to overcome the body's natural resistance to weight loss.

NVIDIA To Re-Enable GeForce 900M Overclocking

Slashdot - Fri, 20/02/2015 - 3:15pm
jones_supa writes: One week after NVIDIA disabled overclocking on their GeForce 900M mobility lineup, a representative of the company has reported that NVIDIA will be bringing back the disabled feature for their overclocking enthusiasts on the mobility front. On the GeForce Forums, he writes, "We heard from many of you that you would like this feature enabled again. So, we will again be enabling overclocking in our upcoming driver release next month for those affected notebooks. If you are eager to regain this capability right away, you can also revert back to 344.75."
