Star Trek-style 'tractor beam' created at university
Scientists at Dundee University have created a working "tractor beam".
Normally the stuff of science fiction in Star Trek or Star Wars, physicists at the university used an ultrasound array to exert force on an object and pull it towards the energy source.
They say it is the first time such a beam has been used to move anything bigger than microscopic targets.
The technology could be put to use in medicine, helping to develop ultrasound-based clinical techniques.
Dundee researchers worked alongside colleagues in Southampton and Illinois on the project, the results of which have been published in the scientific journal Physical Review Letters.
"We were able to show that you could exert sufficient force on an object around one centimetre in size to hold or move it, by directing twin beams of energy from the ultrasound array towards the back of the object."
Now is that cool or what :17:
