In June 2020, Professor ChristianBehl of Mainz University in Germany took over as editor-in-chief of JCB. In the lecture, Professor Behl, Executive Editor of JCB, and Professor Cao Zhiwei, School of Life Sciences, Tongji University, respectively gave wonderful reports on the development of JCB journals and the demand for submission, and actively interacted with online audiences. According to Professor Behl, in recent years, JCB has been deeply troubled by the "paper factory". For the papers accused by the third party, the JCB journal team is conducting detailed investigation and handling according to the operational guidelines of CommitteeonPublicationEthics. In 2020, 23 related papers have been withdrawn. Professor Behl emphasized that withdrawing manuscripts is a means for journals and publishers to correct problems after publishing papers, which can effectively safeguard readers' trust in scientific publications and reflect strict publishing standards.
