Cryptography and carbon: How nanotubes could improve security
Could carbon nanotubes provide intensely secure on-chip encryption for hardware?

Computer scientists at MIT and Harvard University say their Sieve app enables web users to decide which applications access which aspects of their data.
Researchers are using a genetically modified version of the M13 virus, which infects bacteria, to control the arrangement of nanotubes on the surface of solar cells -- improving their efficiency.
Asthma is a common illness which affects at least 300 million people worldwide and which is responsible for about 200,000 deaths every year. But asthma attacks could be detected up to 3 weeks before they happen by testing regularly the breath of asthmatics. If the levels of nitric oxide increase, an attack might happen soon. Now, researchers at the University of Pittsburgh have created a nanosensor to warn about oncoming attacks. It can be encased into a handheld device that people blow into to determine the nitric oxide content of their breath. These sensors have only been tested in the lab, but human clinical trials are on the way, meaning that they might appear on the market in a few years -- and save lots of lives.
Dutch researchers have made what they call the world's smallest piano wire. In fact, these wires are made of carbon nanotubes measuring approximately 1 micrometer long and approximately 2 nanometers in diameter. After applying alternating current of various frequencies to these nanotubes, they started to vibrate like real piano wires.
