A team of research physicists at the University of Dundee in Scotland used energy from an ultrasound array to form a beam that can both carry momentum
to push away an object in its path and, by using a beam shaped like a helix or vortex, cause the object to rotate. The Dundee researchers were able to
lift and spin a free-floating 10 cm diameter rubber disk with the ultrasound beam.
To be honest, I'm not sure. I would just like to point out that "Sonic Screwdriver" is a device used by "The Doctor" in the BBC program Doctor
Who. I believe that the purpose for this will be for surgeries.
As if they have retreived an alien tool and have succeeded to duplicate the science behind it. That is what my first thoughts were. It is kind of
strange coincedence when devices shown in sci-fi movies become reality. Thinking about Capt. Kirk and his communicator and Dr. Spock his poratable
handheld analizer....not to mention transparant flatscreens....stil waiting for transparent alluminium to surface.

Very interesting you say that because if you recall, in Star Trek: The Next Generation, they had an "Internet" of sorts where they had wireless
(wifi) devices that were flat and touch-screen. At the time, it was something that the average viewer thought was just part of the science fiction
genre, but we have things like iPad now.
I wonder if we will have transporters as depicted in Star Trek: TNG.
