HP Labs builds a glasses-free, portable 3D display with wide viewing angles (video)
Typical attempts at a glasses-free 3D display have trouble with viewing angles; we're all too familiar with having to sit in a sweet spot to get the effect. HP Labs might have just solved this last problem with a prototype 3D LCD that would better accommodate the real world. The display's backlight has nanopatterned grooves that send blue, green and red in multiple directions, letting the LCD show only the light that would be seen from a given viewpoint. Those positions are set in stone, but they're both abundant (200 for photos, 64 for video) and can spread across a wide 180-degree viewing arc. At a thickness of as little as half a millimeter, a production LCD could easily be thin enough for a mobile device, too. The catch isn't so much the screen as the content. Producers need an image for every possible viewpoint, which could create a fair share of logistical problems: even though footage wouldn't necessarily require 200 cameras, it could limit fully immersive 3D to computer-generated visuals or else consume a massive amount of bandwidth. If those are the biggest barriers, though, we're still that much closer to the holographic smartphone we've always wanted.
Salt enables six times the storage capacity for snail-unfriendly hard drives
Salt: sure, you might use it to cure meats for your latest solar-powered circumnavigation. But hold onto your kippers, Magellan, because Singaporean scientists have found that sodium chloride -- ordinary table salt! -- can also dramatically increase storage capacity. You see, typical hard drives have randomly-arranged magnetic grains, which allow data density of about 0.5 terabit per square inch. But a high-resolution e-beam lithography process, aided by our good friend NaCl, arranges the grains in a tighter, more orderly fashion, upping the density to 3.3 terabits per square inch. Called nanopatterning, this technique enables a 1TB drive to hold 6TB without additional platters; it also works with current manufacturing technology, meaning no expensive upgrades. If that's got you dreaming of a higher-capacity future, hit the source link for more glorious technical details. We'll warn you, though: the pictures of luscious, bee-stung lips stop here.
