Looking for another way to add some WiDi to your TV? Then you can now also add Belkin's ScreenCast TV adapter to the list of options that are available or imminent. It recently turned up on Belkin's own website with a "coming soon" message, and it's now just hit the FCC, which could mean that "soon" is actually really soon. As for the device itself, it's about as straightforward as you'd expect, with just an HDMI port and some RCA inputs 'round back, plus support for full 1080p video and Dolby Digital 5.1 sound streamed from a WiDi-capable Windows 7 laptop. Look for this one to set you back $129 when it lands at retail.
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
