BOSTON (AP) Researchers who found surgeons can be trained the same way as animals, scientists who examined the bacterial grossness of bank notes and a team that touts the health benefits of pizza were among the winners of this year’s Ig Nobel prizes.

The annual spoof prizes for weird and sometimes head-scratching scientific achievements were handed out Thursday at a ceremony at Harvard University.

Awards were handed out by real Nobel laureates and winners received $10 trillion virtually useless Zimbabwean dollars.

The event was produced by the science humor magazine Annals of Improbable Research and co-sponsored by the Harvard-Radcliffe Science Fiction Association and the Harvard-Radcliffe Society of Physics Students.
