More Retractions from Nobel Laureate Linda Buck

After retracting an influential paper from Nature a year and half ago, Nobel laureate Linda Buck is now retracting two more papers from Science and PNAS, respectively, as they have failed to reproduce the findings in these papers. All three papers were first-authored by Zou Zhihua (邹志华), a Chinese researcher who worked as a postdoc for Buck from 1997 to 2005.

In 2008, Zou wrote in a statement provided by UTMB [University of Texas Medical Branch] that he was "disappointed" by the Nature retraction, he "declined to sign" the Science retraction, as reported online today in Science. But "we have no information to suspect misconduct," Natasha Pinol, senior communications officer at the AAAS/Science Office of Public Programs, told The Scientist in an email.

In addition to the irreproducible results, the PNAS paper also contained "figures inconsistent with original data," according to the FHCRC statement. While the PNAS retraction is "not embargoed," according to Managing Editor Daniel Salsbury, the journal refused to share any information with The Scientist.

Zou Zhihua is reported to be currently in China and unavailable to comment.
