Authors of controversial STAP stem cell study author correct 2011 paper

tissue engineering aThere have been a number of developments in the unraveling of two Nature studies out of the RIKEN Institute in Japan and Harvard purporting to show an easy way to create stem cells. There was an interim report of RIKEN’s investigation last Friday, and more details emerged this week.

And today, the Japan Times reported that last week, a correction of a 2011 paper by many of the same authors appeared in Tissue Engineering Part A. Here’s the correction notice, dated March 13: Continue reading Authors of controversial STAP stem cell study author correct 2011 paper

Hip disjoint: Dysplasia paper lacks proper attribution, earns retraction

ajhbcoverA suggestion: When you title your paper “Joined at the hip?”, better make sure it’s not too close for comfort to someone else’s work.

Alas, an Idaho anthropologist failed to heed that lesson when she published “Joined at the hip? A paleoepidemiological study of developmental dysplasia of the hip and its relation to swaddling practices among indigenous peoples of North America,” in the American Journal of Human Biology last October.

The article, by Samantha Blatt, of Boise State University, found that: Continue reading Hip disjoint: Dysplasia paper lacks proper attribution, earns retraction

Nature paper retracted following multiple failures to reproduce results

nature 2-27-14An international team of researchers from the NIH, Harvard, the University of Michigan, and two Chinese universities — Fourth Military Medical University and China Medical University — has retracted their 2012 paper in Nature after they — and a number of other groups — were unable to reproduce the key results.

The original abstract for “The NAD-dependent deacetylase SIRT2 is required for programmed necrosis” said that the findings

implicate SIRT2 as an important regulator of programmed necrosis and indicate that inhibitors of this deacetylase may constitute a novel approach to protect against necrotic injuries, including ischaemic stroke and myocardial infarction.

But here’s the notice, by corresponding author Toren Finkel and colleagues: Continue reading Nature paper retracted following multiple failures to reproduce results
