We already had a pretty strong inkling that HTC's poorly hidden Droid Incredible 2 would be a world phone, and now we're even more certain (if that's even possible), thanks to this sign / billboard / flyer sent in by an anonymous tipster. What's interesting is how the handset's dual CDMA and GSM connectivity appears to be Verizon's biggest selling point, taking top billing over the front-facing camera and larger screen, which doesn't even get a nod. No word on when this open secret will launch on Big Red, but we say it's about time.
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
