Shane Mayack, a former post-doc in Harvard lab of Amy Wagers, a rising star in the stem cell field, has been sanctioned by the Office of Research Integrity for misconduct. Mayack, who has defended her actions on this blog as honest error — albeit sloppiness — and has not admitted to wrongdoing, must undergo supervision … Continue reading ORI finds Harvard stem cell lab post-doc Mayack manipulated images
Last October, Retraction Watch readers will recall, up-and-coming stem cell researcher Amy Wagers retracted a study in Nature describing how her team rejuvenated blood-forming stem cells in older mice. Shane Mayack, a postdoc in Wagers’ lab who had been dismissed after an inquiry into what happened, did not sign that retraction. Since then, Mayack … Continue reading In a retraction’s wake: Postdoc Shane Mayack, dismissed from Amy Wagers’ stem cell lab, speaks out
Yesterday, we noted that Amy Wagers and Shane Mayack have published five papers together. One of those, published earlier this year in Nature, was retracted Wednesday, and another is now the subject of a “notice of concern” from Blood. We wanted to find out about some of the other papers published by Wagers and Mayack, … Continue reading Editor of another journal where Wagers and Mayack published an abstract is monitoring the situation
A day after an up and coming Harvard stem cell scientist retracted a Nature paper, Blood has issued a notice of concern about another paper by the same group, published in August 2008, the Boston Globe reports. Such notices often, but not always, precede retractions. According to the notice for “Osteolineage niche cells initiate hematopoietic … Continue reading Blood posts “notice of concern” over second Wagers-Mayack paper
More than 14 months after Blood issued a notice of concern about a paper by a Harvard stem cell scientist and her former post-doc, the journal has retracted the article. Here’s the notice for the paper, “Osteolineage niche cells initiate hematopoietic stem cell mobilization,” by Shane Mayack and Amy Wagers:
Amy Wagers, a Harvard stem cell researcher, retracted a Nature study last week and has another published paper under scrutiny at Blood. Retraction Watch has now learned that a 2008 Cell paper she co-authored drew significant criticism from a stem cell researcher at Children’s National Medical Center. In the paper, Wagers and her team said … Continue reading Scientist raised serious questions about 2008 Cell study by Amy Wagers
Last week’s big Retraction Watch news — which got us quoted in the New York Times — was a Nature paper by Amy Wagers and Shane Mayack. The now-retracted paper suggested that the aging of stem cells could be reversed, and Blood has issued a notice of concern about a second paper. Now comes news … Continue reading Another stem cell paper retracted, for “breach of established ethical guidelines”
Amy Wagers, an up and coming stem cell researcher at Harvard who made a name for herself as a postdoc early by questioning the work of others, has retracted a January 2010 paper she co-authored in Nature. According to the retraction: Three of the authors (J.L.S., F.S.K. and A.J.W.) wish to retract this Article after … Continue reading Highly cited Harvard stem cell scientist retracts Nature paper
“Because of its growing reach and influence, Retraction Watch’s investigations and revelations have helped to address the issue of ‘unhelpful retraction notices’.” In 2020, NewsGuard said we were “unsung heroes,” one of ten sites they pointed to as “models in producing content that is truthful, compelling, credible, and transparent.” “The seamier side of academia, lying, … Continue reading What people are saying about Retraction Watch
