A Dundee University project to produce the first working acoustic tractor beam has been named one of the breakthroughs of the year.
The list of scientific accomplishments by Physics World sees the local project side by side with the landing of the Philae probe on to a comet.
The Dundee researchers, working with colleagues at Illinois Wesleyan University in the US, turned science fiction into science fact with their project, creating the first acoustic “tractor beam” that can pull an object by firing sound waves at it.
Dr Mike MacDonald, one of the Dundee team, said: “It is a pleasant surprise to hear that our acoustic tractor beam work is listed in the top 10 breakthroughs of 2014, especially alongside such great physics breakthroughs from around the world.
“It’s particularly pleasing to get such recognition for what is a truly interdisciplinary effort between physics and medicine at Dundee University.”
Dr Hamish Johnston, editor of physicsworld.com, said: “The acoustic tractor beam is a fantastic example of how a simple physics experiment can defy common sense.
“By creating such a tractor beam in the laboratory, the research team will inspire scientists to think differently about ultrasound, which could lead to the development of new and innovative medical applications.”
The research team used energy from an ultrasound array to exert force behind an object and pull it towards the energy source.
It was the first time anyone has demonstrated a working acoustic tractor beam and the first time such a beam has been used to move anything bigger than microscopic targets.
The Philae comet landing was selected as the overall winner for 2014.
