Hurray for science!

Nanotubes Under Stress

Pressing on a carbon nanotube can change its electrical properties,
according to research published in the 18 April PRL. The researchers
experimentally confirmed what some theorists have predicted:
Stretching a nanotube can either increase or decrease its
conductivity--depending on the type of nanotube--by changing the
structure of quantum states available to electrons. The results could
someday allow physicists to build nanotube-based transducers sensitive
to tiny forces.

....and so on.
