We're not professional musicians by a long shot, but when we do get a chance to break away from the relentless torrent of cellphones and tablets, nothing quite hits the spot like a little music appreciation. Of course, when done Engadget-style this usually means a gadget of some sort -- and we'd be lying if we didn't say that Novation's newest didn't whet our appetites for some after-hours beatmatching. Twitch is essentially a full-figured DJ controller, but instead of some sort of round jog wheel (which the current reviewer has always found to be extremely counter-intuitive) the company added a touch strip, which can be used for everything from finding the beat to zooming in and out of the waveform display (after watching the video, it's hard to believe we've been beatmatching without pinch-to-zoom for this long). This bad boy also boasts a full compliment of controls for Serato, Traktor NI, and Ableton Live. You're probably interested in seeing how it performs in the real world, but unless you're in Frankfurt for Musik Messe, you're going to have to settle for the video after the break. Look for it in July for a street price in the $500 range.
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
