Here's yet another juicy leak from China to go with your breakfast. Delivered by the same folks who brought us the sixth-gen iPod nano display module leak, this time we have what appears to be a chassis for the next touchscreen nano. According to Apple.pro, the circular hole at the top right is likely to house a little camera, which would bring back the good old days with the camera-donning fifth-gen nano. Obviously, to make space for such an imager here, the spring-loaded clip on the back would have to be downsized and shifted, which would explain why the four screws are off-centered here, unlike those on the current-gen nano (as seen in iFixit's teardown shot after the break). That said, let's not forget that this rumor is coming straight out of KIRFdom, so we'll remain skeptical until this baby pops out around September time, as has been the case with most nano launches in the past.
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
