Scientist cooks up adjustable strength metals

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 M2432 laptop with GeForce GT 440 graphics card dock hands-on

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

Leadtek AMOR 8218 DECT phone with Tegra 2 Android tablet hands-on

While combing through the show floor at Computex, our fortunate selves stumbled upon a new phone-tablet duo at Leadtek's booth. Oh, don't worry, this isn't yet another phone-in-pad design; but actually a VoIP / home phone docked next to an Android tablet. Dubbed AMOR Multimedia Phone 8218, the idea here is that the docking station acts as both a DECT base and a WiFi router, but also packs ZigBee radio to relay data from compatible devices (for healthcare, home surveillance, home automation, etc.) to the web. Alas, there's no direct interaction between the phone and the tablet, but we were still intrigued by the latter's specs: Android 2.3 (although this demo unit had 2.2), Tegra 2, 7-inch 1,280 x 720 LCD, HDMI-out, and a front-facing camera for video calls. For a home device, this is actually a pretty powerful package and certainly a significant upgrade from the AMOR 8210 announced earlier this year. No word on US availability, but Taiwanese buyers will be able t

Compal's 'Ultra Mobile' Ultrabook eyes-on

Intel's already teased Compal's "Ultra Mobile" Ultrabook from afar, but when this Ivy Bridge laptop popped up on the show floor after the Computex keynote, we decided to give it a closer look. While this prototype isn't quite in the same league as ASUS' gorgeous UX21, do bear in mind that we're still looking at a relatively slim package for a 14- to 15-inch Core i7 rig. Also visible around the machine are a couple of USB 3.0 ports, an HDMI-out port, a LAN socket, and an SD card reader. Until we hear more about this Ultra Mobile, enjoy our eyes-on photos below.

YouTube embraces Creative Commons licensing, turns your cutesy kitty into mashup fodder

Sourcing material from the mecca of viral video has always been a bit iffy -- who knows which rabid Beyonce fan will bite back when you slice and dice their  Single Ladies  tribute video. However, YouTube's recent addition of the Creative Commons licensing option just made it a whole lot easier to make mashups without stepping on anyone's stiletto-sporting toes. Users are now given the option to choose between YouTube's standard license or the Creative Commons Attribution (CC BY) license, which, when selected, automatically adds the video to a library of similarly appointed videos, now available for your cutting and captioning pleasure. An attribution is placed beneath any video sourcing material from the Creative Commons library. Among the more professional outfits adding their videos to the CC pool are  Al Jazeera  and  C-SPAN  -- who's ready to see Mittens the Kitten and Sarah Palin battle it out over tax cuts? You can now access the Creative Commons library through

PhotoFast i-FlashDrive does USB on one end, 30-pin dock connector on the other

Apple's iOS devices may lack native memory expansion, but PhotoFast has now come up with solution that just about bests the official camera connection kit. What you're looking at here is the i-FlashDrive, a memory dongle that sports both a USB plug and an Apple 30-pin dock connector, and it comes in three flavors starting from 8GB at $95 up to 32GB at $180. What's more, the drive also works with a free Cupertino-approved app that provides both external  and  internal file management (for music, photos, movies, and more), contact backup, and native MP3 playback. Want one? Then head over to Taiwan for a mid or late June launch, or watch out for its US debut shortly afterwards. Demo video after the break.
