Do-Over on a Questionable Experiment

Marc Hauser, the Harvard researcher found to be responsible for eight counts of misconduct in his lab, has redone one of his experiments in an attempt to show that his original data was correct, says The Boston Globe's Carolyn Johnson. The paper — published in Science in 2007 — was one of three papers published by Hauser in Science to be called into question, but the journal has said that the new data collected by Hauser and a colleague confirm the original findings, Johnson says. However, Science stresses that the new data bears only on the 2007 experiment and subsequent paper, not on any other of Hauser's work that may also have been questioned.
