crookedvulture writes “Seagate has begun shipping hard drives based on a new technology dubbed Shingled Magnetic Recording. SMR, as it’s called, preserves the perpendicular bit orientation of current HDDs but changes the way that tracks are organized. Instead of laying out the tracks individually, SMR stacks them on top of each other in a staggered fashion that resembles the shingles on a roof. Although this overlap enables higher bit densities, it comes with a penalty. Rewrites compromise the data on the following track, which must be read and rewritten, which in turn compromises the data on the following track, and so on. SMR distributes the layered tracks in narrow bands to mitigate the performance penalty associated with rewrites. The makeup of those bands will vary based on the drive’s intended application. We should see the first examples of SMR next year, when Seagate intends to introduce a 5TB drive with 1.25TB per platter. Traditional hard drives top out at 4TB and 1TB per platter right now.” Read more of this story at Slashdot.

Now, researchers have come up with an alternative, faster strategy for when a pandemic influenza virus surfaces: Just squirt genes for the protective antibodies into people’s noses. The method—which borrows ideas from both gene therapy and vaccination, but is neither—protects mice against a wide range of flu viruses in a new study.” Read more of this story at Slashdot.

However, claims of a 300Gbps attack on Spamhaus are almost certainly false.” Read more of this story at Slashdot. 
pigrabbitbear writes “Complex, socially-tiered societies require complex communication. So perhaps it’s unsurprising that eusocial animals like ants are also incredibly communicative — more so than we previously understood, according to a new study in Current Biology. Many ants begin communicating acoustically from a very young age, in fact, in such a way that scientists suggest may be very important to their survival. As explained in an article by Carrie Arnold at ScienceNow, scientists believed until only recently that ants communicated only through pheromones, leaving, for example, scent trails behind them for other ants to follow — hence the phenomenon of single-file marching ants. (They can also, newer research suggests, use magnetic and vibrational landmarks to guide themselves around.)” Read more of this story at Slashdot.

Together with a current version of libdrm and the Nouveau 3D driver in Mesa 3D 9.0, this allows Linux applications to use 3D acceleration even with the most recent GeForce graphics cards.” Read more of this story at Slashdot. 
MrSeb writes with news on the happenings with next generation fabrication processes. From the article: “… Intel’s 22nm SoC unveil is important for a host of reasons. As process nodes shrink and more components move on-die, the characteristics of each new node have become particularly important. 22nm isn’t a new node for Intel; it debuted the technology last year with Ivy Bridge, but SoCs are more complex than CPU designs and create their own set of challenges. Like its 22nm Ivy Bridge CPUs, the upcoming 22nm SoCs rely on Intel’s Tri-Gate implementation of FinFET technology. According to Intel engineer Mark Bohr, the 3D transistor structure is the principle reason why the company’s 22nm technology is as strong as it is. Earlier this year, we brought you news that Nvidia was deeply concerned about manufacturing economics and the relative strength of TSMC’s sub-28nm planar roadmap. Morris Chang, TSMC’s CEO, has since admitted that such concerns are valid, given that performance and power are only expected to increase by 20-25% as compared to 28nm. The challenge for both TSMC and GlobalFoundries is going to be how to match the performance of Intel’s 22nm technology with their own 28nm products. 20nm looks like it won’t be able to do so, which is why both companies are emphasizing their plans to move to 16nm/14nm ahead of schedule. There’s some variation on which node comes next; both GlobalFoundries and Intel are talking up 14nm; TSMC is implying a quick jump to 16nm. Will it work? Unknown. TSMC and GlobalFoundries both have excellent engineers, but FinFET is a difficult technology to deploy. Ramping it up more quickly than expected while simultaneously bringing up a new process may be more difficult than either company anticipates.” Read more of this story at Slashdot.
