What's better than billions of transistors? Billions of miniature two-nanometer ones, leaving room for billions more. A team of researchers accomplished just that, using the quantum effect to shrink these semiconductors -- and set a new size record in the process -- while also managing to keep them operating at room temperature (note: that photo above is from a different team's study). The team of South Korean, Japanese, and British researchers at Chungbuk National University expect them to "enhance the capabilities of mobile electronic devices" -- a mighty vague claim if ever there was one. Not one for modesty, lead researcher Choi Jung-bum proclaims that it "effectively changes the paradigm of such devices." With no word on mass production, though, we'll just have to wait and see for ourselves how big of an impact these lilliputian circuits will have.
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
