It was just two short months ago that Sony had us drooling over its latest OLED monitors. But, at the double-take-inspiring price of $16,000, its safe to assume the company isn't moving too many of these professional-level displays. For film and TV production companies turned off by the high-priced BVMline, Sony has announced the PVM-2541 and PVM-1741, which arrive at less than a third of the cost. The 25-inch and 17-inch screens (we're sure you can guess which is which) will retail for $7,400 and $4,900, respectively, while boasting the same 1080p, "Super Top Emission" panels (explained in the lengthy video after the break) and 10-bit drivers of their more expensive cousins. The one trade off is the significantly smaller, 89-degree viewing angle. Good thing movie editors are used to huddling uncomfortably close together.
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
