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

Scientists fabricate a paint that destroys deadly MRSA bacteria

MRSA bacteria is a virulent bacteria that breeds in hospitals, killing patients who are recovering from surgery or other ailments. But now we can create MRSA-free hospitals, by painting them with a special substance that kills MRSA without antibiotics. » 8/16/10 3:27pm 8/16/10 3:27pm

Nanotech And Lasers Team Up To Cure Cancer

When nanotech and lasers team up, is there anything they can't do? Apparently not. New research shows a combined nanotube/laser treatment zaps kidney tumors in 80 percent of mice. Nanotech is teaming up with viruses to kill ovarian tumors, too. » 8/31/09 1:20pm 8/31/09 1:20pm

Carbon Nanotubes Cook Cancer

The world needs new ways of murdering cancer cells, and scientists at the University of Texas Southwestern Medical Center have delivered. Their weapon? The much-hyped carbon nanotube, which apart from being electrically conductive, able to be woven into stronger-than-steel fabrics, and just all-around awesome, also… » 6/17/08 7:00am 6/17/08 7:00am

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

NASA Wants To Slice Your Brain With Nanoknife

Carbon nano-tubes aren't just gorgeous, they might also save your brain one day. NASA's Jet Propulsion Laboratory is teaming up with a cancer center, City Of Hope, to develop a new minimally invasive type of brain surgery using carbon nanotubes. Researchers hope that these sharp-tipped tubes, 50,000 times narrower… » 1/24/08 2:30pm 1/24/08 2:30pm

A Nanotech Twist on Silkworms

Microchip construction has gone biological. UC Riverside announced last week that some of its researchers had discovered that the metal-corroding bacteria Shewanella extrude semi-conducting nanotubes that can be used for microchips or other tiny electronics devices. Here you can see a nest of Shewanella and tubes.… » 12/13/07 11:00am 12/13/07 11:00am
