WEST LAFAYETTE, Ind. (AP) — Purdue University on Wednesday reprimanded a scientist who has been accused of falsifying claims he produced nuclear fusion in tabletop experiments.

Rusi Taleyarkhan made headlines in 2002 when he published a paper in the journal Science claiming that he had produced nuclear fusion, long sought as an energy source by scientists, by making tiny bubbles collapse in a liquid.

A university panel did not investigate the Science paper, which was published when Taleyarkhan was a researcher at Oak Ridge National Laboratory in Tennessee, but said he misled the scientific community by claiming his "bubble fusion" findings had been independently replicated.
