Scientists propose a 'journey to the mantle of the Earth'

This particular "journey" may not involve any humans descending into the Earth, but that doesn't mean it isn't still plenty ambitious -- a pair of scientists are now proposing to drill to the Earth's mantle and bring back some samples, effectively picking up where the first attempt to do so left off some fifty years ago. Of course, the key word here is "proposing," but the scientists, Damon Teagle and Benoît Ildefonse, say that we now have the technology and knowledge necessary to do so, and that drilling could begin by 2020 if everything goes as planned. They're looking to get things underway well before that, however, and are already planning an expedition in the Pacific as soon as next month where they say they will "bore further into the oceanic crust than ever before."

Samsung confirms WiFi-only Galaxy Tab availability: April 10th, $350

We've already seen it turn up on a few retail sites, but Samsung has now finally officially confirmed the launch details for its WiFi-only Galaxy Tab. It will be available online and at retail stores across the US on April 10th for $349.99. Specs otherwise remain the same as the 3G version, including a 7-inch 1024 x 600 display, 32GB 16GB of internal storage (with a microSD card slot for up to an additional 32GB), rear and front-facing cameras, and Android 2.2 with support for Flash 10.1 -- from the looks of things, it's also only available with a white back.

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

Commodore USA puts the new C64 up for pre-sales, unveils far-less-retrotastic VIC-Slim

Desktops Commodore USA puts the new C64 up for pre-sales, unveils far-less-retrotastic VIC-Slim By Sean Hollister posted Apr 6th 2011 8:43PM Now that Commodore USA has sufficiently piqued your curiosity with a revamped Commodore 64 prototype, it's ready to capitalize on the idea. Quite literally, we might add. $595 buys you the basic basic model with an 1.8GHz dual-core Intel Atom D525 chip, NVIDIA ION 2 graphics, 2GB of RAM and a 160GB hard drive -- which it promises to deliver by "early June" -- with hundred-dollar increments adding premium features like an additional 2GB of memory, a Blu-Ray drive, up to 1TB of storage, 802.11 b/g/n WiFi and Bluetooth. However, if you're simply looking for a compact keyboard computer (rather than reliving 80's nostalgia) there's another option on tap -- a likely rebadged thin wedge of a machine that Commodore's...
