If you're a Sprint Premier customer and are planning to purchase the company's eccentric dual-screen Android smartphone, listen up. Yes, it's due to launch in just three days, but the wireless company is now offering its loyal customers a chance to order the Echo right now. If you decide to jump the gun, you'll be happy to know that Sprint is waiving upgrade fees and will ship you the device for zero bucks. So, if this offer sounds tempting -- and you qualify -- hit the source link to get a 72-hour advantage on everyone else.
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
