Special Online Collection: Hwang et al. Controversy --
Committee Report, Response, and Background

On December 1, 2006, Science published, on this Web site, the report of a committee commissioned by the journal to review its practices in the period leading up to the publication of the 2004 and 2005 stem cell papers by Hwang et al., which were subsequently retracted. On this page, we are making available direct links to the report, Science's response, and an accompanying editorial.

To provide additional context on the history of the controversy, we also provide on this page links to Science's editorial retraction of the papers and other official statements on the situation, the original Science papers, associated news coverage on the controversy, letters and a Policy Forum on the controversy, and another Policy Forum on stem cell ethics published earlier in 2005.

Committee Report and Science Response

In its 1 December issue, Science published an editorial, authored by Editor-in-Chief Don Kennedy, discussing the journal's internal review process in the wake of the Hwang scandal, as well as the review conducted by a committee including members of the journal's Senior Editorial Board, the U.S. executive editor of another major scientific journal, and two distinguished members of the stem cell research community. Links to the editorial and associated report appear below.
