Another Samsung WiFi Galaxy Tab 10.1 hits the FCC, this time dubbed GT-P7310

This week brought news that Samsung's Galaxy Tab 10.1 would be released into the wild in just a few days. Today, a WiFi tablet from the Korean company made its way through the FCC bearing model number GT-P7310. Which, you see, is slightly different from the GT-P7510 moniker we saw in anotherFCC filing earlier this month, and this ended up being the limited edition 10.1 passed out at Google I/O. While some may think that this could well be the 8.9-inch version of Sammy's Android tablet, the above drawing is actually identical to the previous one bar the extra text at the bottom, so our money's on 10.1 again -- maybe this variant is destined for other countries? We shall see.

Update: A bit more digging found a pair of 10.1-inchers demonstrated in Monaco with models listed as the GT-P7300 (a WiFi plus 3G Galaxy Tab 10.1) and GT-P7310, which, you guessed it, is a WiFi-only version.

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

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.

TDK starts mass production of transparent OLEDs, makes texting and walking safer

TDK is taking those transparent OLED screens we saw back in October and putting them into mass production. The 2.4-inch, QVGA (240 x 320) UEL476 display has a transmittance of 40 percent, but obscures light passing through the front so others won't be able to read your text messages from behind. Obviously, these aren't going to find their way into high-end Android handsets, but they may have a home in fashion phones like Lenovo's S800. And, you know, they seem perfect for SMS addicts who can't stop their thumbs from flying even while walking.
