A neuroscientist whose revealed analysis has been embroiled in accusations of symbol manipulation and duplication has introduced his resignation from the College of Minnesota, efficient March 1.Sylvain Lesné had endured his analysis on the U in recent times, whilst issues emerged and forced a retraction final 12 months of one in all his landmark papers that had pointed to new instructions in treating Alzheimer’s illness.A college spokesperson showed the resignation in a written commentary Monday — with out rationalization as to why — however famous the college has lately alerted clinical journals to “information integrity issues” with 4 further publications Lesné co-authored.“The College … has been involved with the ones journals to counsel retraction of the publications, the place suitable,” the spokesperson stated.Lesné didn’t reply to a request for remark Tuesday.
