Breast cancer stem cells, the slow-growing, hard-to-kill malignant cells that are thought to be responsible for the growth and spread of breast cancer, have proven remarkably resistant to traditional chemotherapy and radiation therapy. Now, researchers at Wake Forest Baptist Medical Center have shown that multi-walled carbon nanotubes (MWCNTs) injected into breast tumors and irradiated with a quick, 30-second laser beam, are effective at killing breast cancer stem cells.

A sponge made of pure carbon nanotubes with a dash of boron shows remarkable ability to absorb oil spills from the surface of water, according to researchers at Rice University and Penn State University. The oil can be stored in the sponge for later retrieval or burned off so the sponge can be reused.

Scientists and engineers at the University of Wisconsin-Milwaukee (UWM) have discovered an entirely new carbon-based material that is synthesized from the “wonder kid” of the carbon family, graphene. The discovery, which the researchers are calling “graphene monoxide (GMO),” pushes carbon materials closer to ushering in next-generation electronics.

MIT engineers are using carbon nanotubes only billionths of a meter thick to stitch together aerospace materials in work that could make airplane skins and other products some 10 times stronger at a nominal increase in cost.

New research by MIT scientists suggests that carbon nanotubes -- tube-shaped molecules of pure carbon -- could be formed into tiny springs capable of storing as much energy, pound for pound, as state-of-the-art lithium-ion batteries, and potentially more durably and reliably.

Carbon nanotubes have been accidentally created by the forgers of Damascus steel, a process that no longer exists today.
It appears to be the nanotubes and cementite nanowires that give it it's legendary strength along with it's intricate patterning.

Companion story for the swords. More on the chemistry.

I think the process of Damascus and Samurai steel making are somewhat similar? Folding harder and softer steels together? I can't find where they have looked for nano-tubes in a samurai sword, yet.
Here are more usages: http://www.understandingnano.com/nanotubes-carbon.html
Some are un-expected, to say the least.

I seem to recall the bone healing didn't pan out.? Can you post an article, I would be interested in reading about it. TY

MIT chemists designed a new type of pencil lead consisting of carbon nanotubes, allowing them to draw carbon nanotube sensors onto sheets of paper.
"A new fabrication method created by MIT chemists as simple as drawing a line on a sheet of paper may overcome that obstacle. MIT postdoc Katherine Mirica has designed a new type of pencil lead in which graphite is replaced with a compressed powder of carbon nanotubes. The lead, which can be used with a regular mechanical pencil, can inscribe sensors on any paper surface."

modern "damascus steel" is pattern welded for exotic patterns.
and even colours! soo swanky! do want!
older "damascus steel" was also pattern welded but the process resulted in a superior steel before modern industrial smelting and factory controls allowed for a superior homogenous steel product. old damascus shotguns (still common) burst if you use modern shells in them. the pattern welds degrade over time resulting in de-lamination of the many layers.
the legendary True Damascus steel is to my knowledge lost forever, and i have yet to hear of an original True Damascus example being studied anywhere, only medieval pattern welded blades, and examples of wootz steel.
the japanese technique was quite different from western pattern welding.
