We just heard talk of a new 15.6-inch Dell laptop yesterday that was said to be thin and streamlined, andMobile Review has now scored some pictures of what may be that very same laptop. While there's unfortunately not much in the way of details, the laptop is apparently dubbed the XPS 15z, and it's said to pack support for Sandy Bridge Core i5 and Core i7 processors. As previously hinted at, this particular laptop is also said to be just part of a series, with both 14-inch and 17-inch models also on the way. Hit up the link below for few additional shots.
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
