In the 16 September 2011 issue, Science published the Report “Unclicking the click: Mechanically facilitated 1,3-dipolar cycloreversions” by J. N. Brantley et al. (1).

After concerns were raised in an e-mail to the editors from a reader, the corresponding author supervised a comprehensive evaluation of all data presented in the original manuscript by tracing all figures back to their raw data files. In over 50% of the figure parts, the authors deemed the data unreliable due to uncertainty regarding the origin of data or the manner in which the data were processed. A confidential investigation that is relevant to these concerns is currently being conducted by the University of Texas at Austin.

Pending the conclusion of the investigation, Science is publishing this Editorial Expression of Concern to alert our readers to the fact that serious questions have been raised about the validity of findings in the Brantley et al. paper.
