Is bubble fusion back?

Physicists at Purdue University in Indiana claim to have found new evidence for nuclear fusion in a tabletop device. Yiban Xu and Adam Butt say that firing sound waves into a beaker of deuterated acetone that has been "seeded" with neutrons produces tritium and further neutrons through the process of fusion. Known as "bubble fusion", the phenomenon met with widespread scepticism when it was first reported in 2002. The new results are likely to be just as controversial.
