As corresponding author of the above paper, Dr K. Siegers has informed the journal that Figures 2A, 3A,B and 5A of this publication contain inappropriately processed or fabricated data. Although an investigation of this case by the Max Planck Society has indicated that the main conclusions of the study appear not to be affected by these manipulations, both Dr Siegers and her co-authors agree to retract this paper. In view of this misrepresentation of data, authors S.G., J.P.S., U.M.K.B., A.B. and F.U.H. have informed the journal that they wish to retract their names from the original publication.
