robots
These robots are just the size of a hair, but up to five of them can be independently, wirelessly controlled to work (and dance) in harmony. The robots are able to move by inch-worming 10-20 billionths of a meter at once somewhere around 20,000 times a second. The result is small robots that can make their way around with relative alacrity, but still home in on precise movements. And the example video is pretty remarkable:

MIT Nanomesh Paper Towel is the Last Quicker Picker Upper You'll Ever Need
Sorry, Brawny man. Your paper towels were always handy in a pinch for the occasional Coke-on-keyboard spill, but they fall apart when held up against this incredible nanomesh towel from the folks at MIT. Designed with the environmentally unfriendly act of oil spills in mind, this recyclable towel's potassium manganese oxide fibers absorb up to 20 times their weight in oil (which can then be recovered, for future oil spills).

Study Kicks Nanotech Right in the Buckyballs
Just last week, we heard that carbon nanotubes could be as dangerous as asbestos. Now a new study takes another damning shot at nanotechnology, this time at the sector's golden child, buckyballs. Hollow balls of carbon that are promising for everything from fighting cancer to coating paint, a recent study found that buckyball clusters can easily penetrate cell membranes and hang out inside, their molecular structures fully intact.

Group Sues EPA For Not Regulating Nano-Silver Pollution
Those nano-silver socks you've been using to soak up the rank of your athlete's foot—not only are they leaching poisons into fish habitats every time you wash them, their effects on your own blood stream could be just as bad; but the EPA's not doing anything about it. Fed up by government inaction, a consumer safety group is now suing the EPA for failing to regulate nanomaterials. More »

A Round of Applause for the Gonorrhea-Based Molecular Machine
Gonorrhea isn't just an STD known for causing burning sensations when you pee; it's the strongest organism known to man. Able to pull 100,000 times its body weight, the clap may soon serve a purpose greater than painfully reminding you of nights spent cruising the Red Light District. Scientists hope to use gonorrhea bacteria in nanotech devices because of the strong forces they can exert on nearby objects. In the clip above, gonorrhea is using pili filaments it produces, which are 10 times longer than the bacterium itself, to pull tiny columns. More »

A nanotech invention by a US research team offers an intriguing glimpse of the future: slip on some nanowire-embedded clothes, plug your MP3 player or cellphone into them, and as you dance or walk around, your outfit generates enough power to run the gadget. More details on how the fabric works, and some nano-imagery after the jump.

Nanotech Coating Uses Sunlight to Banish Smelly Socks Forever
Scientists in China and Australia have developed a method of cleaning fabric using nanotechnology that avoids dunking clothes in soapy water, before scrubbing and rinsing. The titanium dioxide-based coating bonds to silk and wool and uses sunlight to automagically decompose dirt, stains and microorganisms, meaning smelly socks could be a thing of the past—something that teenage boys' moms will applaud the world over.

A team of researchers at UC Berkeley have invented a radio made of a single carbon nanotube. The device is just a few billionths of a meter in size - so small that it could fit inside a living cell, or float along in your bloodstream. According to physicist and project lead Alex Zettl, who helped researcher Kenneth Jensen come up with the idea for the radio:

A Fully-Functioning Nanotube Radio
A team of researchers at UC Berkeley have invented a radio made of a single carbon nanotube. The device is just a few billionths of a meter in size - so small that it could fit inside a living cell, or float along in your bloodstream. According to physicist and project lead Alex Zettl, who helped researcher Kenneth Jensen come up with the idea for the radio:A single carbon nanotube molecule serves simultaneously as all essential components of a radio — antenna, tunable band-pass filter, amplifier, and demodulator. Using carrier waves in the commercially relevant 40-400 MHz range and both frequency and amplitude modulation (FM and AM), we were able to demonstrate successful music and voice reception.

Swarms of Magic Smart Dust to Explore Other Planets
Nanotech scientists at the University of Glasgow are figuring out how to use smart dust to explore planets. Each piece of dust would be about a millimeter wide, and would have a processor, sensors, a generator and digital communications gear on board. It would be covered with a shape-shifting plastic sheath that would allow it to be steered, gliding with planetary winds and returning data to its mother ship. More »

Nanogenerator Magically Cranks Out Watts From the Environment
We're thinking this nanotechnology thing is catching on big-time. First someone figured out how to use the technology to keep panties fresh and odor-free, and now brilliant scientists have been developing small generators that might just be able to someday do away with batteries. They're first trying to develop a way to power those devices that are so minuscule you could fit thousands of them on the head of a pin. More »

Strom Fishing Lures Use Nanotach to Catch Four Times More Fish
Nanotech is creeping into our lives, and now it surfaces in fishing lures, where vacuum equipment manufacturer Ulvac has created Strom, an especially shiny fishing lure with an optical coating that uses nanotechnology. The trick here is its holographic color that keeps its shininess regardless of the viewing angle. That will theoretically attract the attention of veritable universities of fish. More »
