Harvard professor found guilty of scientific misconduct

Harvard professor found guilty of scientific misconduct: "Since the investigation began in 2007, several papers coauthored by Hauser have been called into question. The first was a study published in the journal Cognition in 2002 that asserted that cotton-top tamarins can identify changes in syllable patterns; this paper was retracted when the investigation found that 'the data do not support the reported findings.' A 1995 PNAS paper reported that cotton-top tamarins can recognize themselves in a mirror, a result that is surprising because this new world monkey species is not known to have advanced cognitive abilities. When questions were raised about the findings, Hauser repeated the experiment and found that the results held: the monkeys again aced the mirror test, indicating self-recognition."
