Scientists have used carbon nanotubes to engineer the most powerful…

Will the wonders of carbon nanotubes never cease? Engineers have now used everyone's favorite cylindrical übermolecules to create artificial muscles that can contract and twist, in a manner not unlike like the muscles found in elephant trunks and squid tentacles. The upshot? Researchers say these tiny little motors… » 10/14/11 1:20pm 10/14/11 1:20pm

Nanotechnology: what is reality and what is magic?

Arthur C. Clarke famously said that "Any sufficiently advanced technology is indistinguishable from magic." I always keep this quote in my mind when reading science fiction and try to spot where things become indistinguishable from magic. They always do. One of the most popular ways in modern sci-fi to get away with… » 2/13/11 6:00pm 2/13/11 6:00pm

Nanotech Precisely Measures Spiciness So Your Tongue Doesn't Have To

The Scoville Units you see on the side of chili sauce bottles are measured subjectively by taste testers, who determine how hot a given hot sauce really is. But now a new nanotechnology will allow food scientists to quickly and cheaply measure the exact amount of capsaicinoids — the active component in chili peppers… » 5/09/08 8:00am 5/09/08 8:00am

Today A Nano-Radio, Tomorrow A Micro-Semiconductor

A radio made out of carbon nano-tubes could get better reception, than the current bulky silicon-based models. Researchers led by John Rogers at University of Illinois solved the amplification problems that had stymied previous nano-radios by making their radio on a quartz wafer the size of a grain of sand. The other… » 1/30/08 6:30am 1/30/08 6:30am
