Dr Who's sonic screwdriver 'invented' at Dundee University

The Dundee University researchers have created a machine which uses ultrasound to lift and rotate a rubber disc floating in a cylinder of water.

It is said to be the first time ultrasound waves have been used to turn objects rather than simply push them.

The study could help make surgery using ultrasound techniques more precise, the physicists said.

Surgeons use ultrasound to treat a range of conditions without having to cut open a patient.
