John Hart, a professor at the University of Michigan, has created a super-small tribute to President-elect Obama using 150 million nanotubes. (Each one is less than a millimeter in diameter and can only be seen through a microscope.)

A carbon nanotube composite material called buckypaper promises to be10 times lighter than steel but up to 500 times stronger. Florida Advanced Center for Composite Technologies (FAC2T) under the direction of Ben Wang, is working to develop real-world applications for this super material.
"The U.S. military has shown a keen interest in the military applications of Wang's research; in fact, the Army Research Lab recently awarded FAC2T a $2.5-million grant, while the Air Force Office of Scientific Research awarded $1.2 million." BuckyPaper.com
Buckypaper is a true wonder material
Buckypaper will most likely first be used in military aircraft and cruise missiles. Its electrical conductivity would provide protection from lightning and electromagnetic interference. When the cost of producing buckypaper comes down its strength to weight ratio will help make everything lighter and stronger. Its ability to dissipate heat will also be useful in computer circuits.

Hey, wait a second...: How could you ever balance one of those on a pencil? Bad science!

I knew you were. You’re Buzzketeers, the best of the best, the biggest of the brains, the coolest of the cids.
There’s no need to explain graphene to this team (the Lil’ Professors), so it would be totally unnecessary for me to point out that graphene is a fancy material made of a single layer of carbon atoms attached to each other in a honeycomb pattern. It’s about as flat as can be, and when you roll it up you get those little things Science Buzz is so crazy about: carbon nanotubes.
Nanotubes are awesome, and if you click on the link above you can learn about all the awesome things they can do. But graphene…graphene itself may be pretty awesome too. The problem with testing just how awesome graphene is is that it has been exceptionally difficult to a) make a piece of graphene so small that it hasn’t got any of the imperfections that naturally come in large chunks of things, and b) make a device to actually hold the itty bitty graphene well enough to really test the stuff out.
But science has now done those things! Using a tiny sheet of perfect graphene (about 1/100s the width of a human hair) and a really tiny diamond…poker-thing (about 10 billionths of a meter wide), scientists have finally been able to find out exactly how strong graphene is.
So, how strong is it? It’s the strongest! That is to say, the strongest material measured so far. It’s about 200 times the strength of structural steel, or, says Columbia Professor James Hone, “It would take an elephant, balanced on a pencil, to break through a sheet of graphene the thickness of Saran Wrap.”
This statement, of course, wins professor Hone July’s “Awesome explanation, Scientist” award. That’s a good mental image, and it shows a non-scientist like me how strong graphene is.
So…awesome explanation, Scientist! More of that, please!
Carbon nanotubes
Courtesy St StevA new study published in the scientific journal Nature Nanotechnology shows that longer fibers of carbon nanotubes seem to mimic asbestos when injected into the abdomens of mice. This raises new safety concerns for the up-and-coming technology.
When the mice were injected with asbestos and with various sizes of carbon nanotube samples, the researchers discovered that the longer nanotubes acted in the same way as the asbestos, causing inflammation and lesions. Exposure to asbestos is considered the main cause of a cancer known as mesothelioma.
Just like nanotechnology today, asbestos was once considered a wonder material until its cancer-causing effects on the protective covering (mesothelium) of the body’s organs were realized.
