Senior Associate and IMM researcher Josh Hall writes "An article in the current Science, Low-Friction Nanoscale Linear Bearing Realized from Multiwall Carbon Nanotubes, by John Cumings and A. Zettl, describes recent work that will be very important in terms of building nanomachines with sliding parts. If you have an online subscription, read it here.

There is a "perspective" entitled "NANOTECHNOLOGY: Beyond Gedanken Experiments" by Laszlo Forró, which mentions that the technique was foreseen by Drexler and references Nanosystems. It's here.
It's good to see this on the heels of stories such as this cover story in Science News about "stiction", the bane of MEMS microdevices."
