From yesterday's New Zealand Herald newspaper (31 October, 2015) ...

Fiction to fact: Star Wars tractor beam
---------------------------------------
Remember the tractor beam from 'Star Wars' that pulled the
Millennium Falcon into the Death Star? It might become the
latest piece of science fiction to turn science reality,
with Spanish and UK researchers finding that sound waves
could be used to lift up tiny things and move them. By
co-ordinating the timing of the waves, the researchers
were able to make objects smaller then 1mm levitate, move,
and spin. They also studied the possibility of acoustic
structures such as tweezers, twisters, and bottles, which
can be used as "tractor beams" for container-less
transport.


Wow! A whopping whole "smaller than 1mm" .. that's going to be
extremely useful for transporting, ...err, nanobots around. ;-)
