Hasta La Gadget!

Here’s some exciting news for all you data storage enthusiasts and academics out there: researchers in France have found a way to double the storage capacity of magnetic disk drives by constructing “3D towers” of information. The team from SPINTEC created these pillars out of bit-patterned media — separated magnetic nanodots, each of which carries one bit of data. By layering the dots in specific formations, the team created a “multilevel magnetic recording device” with an areal density of two bits per dot — twice what it started with. According to researcher Jerome Moritz, these findings could provide IT companies with a new way to circumvent physical limitations to their data storage capacities, allowing them to build up and over the vaunted one Tbit per square inch barrier. The team’s full findings were recently published in the American Institute of Physics’ Journal of Applied Physics.

Well, this might be a good reason for The Powers That Be to know your exact whereabouts. According to a team of MIT researchers, speeding up data rates on mobile devices could be as easy as tapping the various motion sensors found in run-of-the-mill smartphones. The scientists believe our wireless infrastructure is at the root of bottlenecks, with a handful of weak transmitters clumsily “handing off” data to one another as you move out of range. The solution: use GPS radios, accelerometers, and even gyroscopes to infer where you’re headed, and then choose an access point near where you’re likely to end up. The difference, they report, is dramatic: a 50 percent boost in throughput, along with improved success in choosing the best bit rate. To boot, if a base station is armed with location-based info, it can better predict when the devices connected to it are on the verge of losing contact. That’s all good news, but sadly we doubt any amount of promising science is enough to make the pink lady go away.

As trippy as mind-control still seems to us, we’ve already seen it implemented in everything from wheelchairs to pricey gaming (and car driving!) headsets. But the problem is that they measure brain activity outside the skull — you know, the thing we’ve evolved to shield the murky goings-on in our minds from prying EEG sensors.

Now, though, a team of Washington University researchers appears to have happened upon a more effective — albeit, invasive — approach. The researchers got some brave specimens to move a mouse cursor by implanting plastic pads containing electrodes underneath their skulls, with the sensors sitting on the surface of the brain. That, they say, gives them access to more telling, high-frequency waves that say a lot more about cognitive intentions. In the end, the subjects moved the cursors by thinking one of these sounds: “ee,” “ah,” “oo,” and “eh.” Brain-computer interfaces ain’t new, of course, but the scientists say the subjects with electrode implants had more success than people wearing electrode-studded EEG caps, which could translate to less frustration for people with severe disabilities.

NASA’s already given us a glimpse at its Mars rover, courtesy of a USTREAM broadcast a few months back, but the crew over at BoingBoing has taken one small step for mankind by going even further in-depth with Curiosity before it launches in November. One lucky photographer was granted permission into the Jet Propulsion Laboratory in Pasadena, and the fruits of his bunny-suited labor showcase the nooks and crannies of NASA’s latest and greatest. We’re still kind of bummed that the rover won’t be equipped with a zoom 3D camera as originally planned, but we’ve got a hunch James Cameron’s taking it even harder. Be sure to hit the source link for a whole smattering of more angles, if intergalactic spacecrafts are your thing.

The internet is a mighty big place that’s only growing larger each day. That makes it a perfectly unwieldy thing to measure, but the traffic it generates has nonetheless been subjected to a rigorous estimation project by a group of UC San Diego academics. Their findings, published online this month, reveal that in 2008 some 9.57 zettabytes made their way in and out of servers across the globe. Some data bits, such as an email passing through multiple servers, might be counted more than once in their accounting, but the overall result is still considered an under-estimation because it doesn’t address privately built servers, such as those Google, Microsoft and others run in their backyards. On a per-worker basis (using a 3.18 billion human workforce number), all this data consumption amounts to 12GB daily or around 3TB per year. So it seems that while we might not have yet reached the bliss of the paperless office, we’re guzzling down data as if we were. Check out the report below for fuller details on the study and its methodology.
