Claims that a team of US researchers have achieved nuclear fusion in a small tabletop experiment have split nuclear physicists - with some expressing enthusiasm and others grave concern.

The research, to be published in Friday's issue of the journal Science but widely leaked, was undertaken by scientists at Oak Ridge National Laboratory in Tennessee, and at the Rensselaer Polytechnic Institute in New York.

They are reported to have fired ultrasound at liquid acetone causing minute bubbles to collapse at temperatures of millions of degrees.
