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
Gigabyte's no stranger in the field of dockable computing devices, and its M2432 laptop shown off atComputex is yet another example proving just this. Let's focus on the actual machine first: here we have a Core i5-2410M (2.3GHz to 2.9GHz) rig packing a 14-inch 1,366 x 768 LCD, Intel HD Graphics 3000, 4GB of DDR3 RAM, 500GB 7200rpm hard drive, and a DVD burner that can be swapped with a secondary battery. You'll also find 802.11 b/g/n WiFi, Bluetooth 3.0, HDMI-out, VGA-out, 1.3 megapixel webcam, an eSATA/USB 2.0 combo port, and two USB 3.0 ports on this Windows 7 Home Premium laptop. All of this weigh 1.8kg (3.97lbs). There's a bit of a surprise inside the expansion dock: by laying the M2432 on top of it, not only are you adding six extra USB 2.0 ports plus DVI-out and another HDMI-out, but you're also kicking up its graphics power with the built-in desktop-class NVIDIA GeForce GT 440 with 1GB video RAM. So essentially, the dock doubles as an external graphics ca
