Research Fodder April 16, 2014

Until late November 2005, Hwang was criticized only for unpublicized ethical violations. Colleagues and media outlets asserted that he had paid female donors for egg donations and that he had received donations from two junior researchers, both of which were violations. Later controversies would center around scientific misconduct. His team, which cloned the first human embryo to use for research, said they had used the same technology to create batches of embryonic stem cells from nine patients.
