NHK demos Hybridcast streaming, teams up internet and cable TV for superior 3D delivery

With all the hubbub surrounding competing 3DTV technology, it's easy to forget the all importantdelivery process: how is your TV getting its content, and what does it mean for the viewer? It may seem trivial, but the answer is all-too important to the folks at NHK, who are hoping to facilitate Full HD delivery for 3D content using a new hybrid broadcast system. Think you already have Full HD 3D? Think again: most broadcast 3D content is delivered via side by side transmission, forcing two images (one for each eye) into a single 1080p frame. This allows 3D content to pipe through existing HD channels, but when the separate images are reconstituted and upscaled, resolution and picture quality suffer. NHK hopes to resolve this by fusing broadcast transmission with broadband streaming, what it calls Hybridcast. In a recent dual-stream demo, NHK sent the image for one eye over standard HD TV broadcast pipes, and the other through those wondrous internet tubes, eventually reassembling the two streams into a single, Full HD image, ready for your hungry eyeballs. This prototype delivery system is little more than a demo right now, but with any luck, it'll be giving us a whole new reason to freak out about broadband bandwidth caps in the near future.

Manual for Alienware M11x with Sandy Bridge confirms NVIDIA GT540M graphics

If the previous Alienware M11x R3 spec leak got you all giddy, then we have some good news for you: according to a manual dug up by one of our eagle-eyed readers, it appears that this year's M11x refresh will indeed be coming with second-gen Core i5 ULV and Core i7 ULV options, along with a faster DDR3 bus (1333MHz instead of 800MHz), a higher-res webcam (2MP instead of 1.3MP), an HD TrueLife LCD, and optional 3G / 4G mobile broadband. But of course, the real meat on this laptop is its graphics card, which turns out to be an NVIDIA GeForce GT540M with either 1Gb or 2GB of dedicated memory -- not bad for a laptop of this size. Unsurprisingly, no dates or prices are mentioned here, but given the early start of inventory clearance, it shouldn't be long before Round Rock reveals all. Dell (ZIP)

Scientist cooks up adjustable strength metals

As you may know, crafting a katana is a delicate process that involves carefully constructing a razor-sharp high-carbon edge around a soft shock-absorbent core. One day though, smiths and forging fires could be replaced by electrode-wielding mad-scientists, with the technology to selectively harden and soften metal at will. At least that's what we envisioned when we read about Jörg Weißmüller's breakthrough research in the field of nanomaterials. The German scientist discovered that by placing precious metals in acid he could create tiny ducts through corrosion. Once those channels are flooded with a conductive liquid, electrical currents can be used to harden the material and, if you change your mind about the brittle results, the effect can easily be reversed to make it soft again. The tech could eventually lead to self-healing vehicle armor or scratch-resistant cellphones -- but, really, we just want to zap our way to a high-quality samurai sword. Physorg

Test subjects with electrode implants use mind control to move a cursor

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, b...
